Chapter 1877

Abandoned steel factory.

After discussing for a while, everyone finally decided to bring the deceased back to the Technical Section of the Municipal Bureau for further body examination.

But at the same time that Gao Chuanfeng ordered two trainee forensic assistants to lift the corpse and put it into a decorative bag, Gu Chen suddenly discovered that there seemed to be a wound on the back waist of the deceased.

Seeing this situation, Gu Chen hurriedly interrupted: "Wait a minute first."

"What's the matter, Gu Chen?" Gao Chuanfeng was taken aback, and asked Gu Chen too.

"Put it down first, put down the corpse first." Gu Chen pressed his hands and said.

The two forensic assistants carrying the corpse couldn't help but look at each other, and then looked at Gao Chuanfeng.

Gao Chuanfeng also signaled and said, "Let it go first."

The corpse was placed on the ground again. At this time, Gu Chen hurriedly swept up the top of the corpse to check the abnormality he found just now.

At this moment, everyone discovered that the place Gu Chen wanted to check was a long scratch on the lower back of the deceased.

Since it was an old wound, it seemed that the wound had already solidified, but the scratch marks were still very obvious.

Lu Weiwei didn't know what was going on, so she hurriedly asked Gu Chen: "Junior Brother Gu, is this what you want to check?"

"Yes." Gu Chen didn't evade, but said bluntly: "There seems to be something wrong with the wound on his back."

"Wound?" Gao Chuanfeng confirmed it again, and said casually, "An ordinary scratch, is there a problem?"

"Then do you know how he got scratched?" Gu Chen said.

Everyone was stunned and looked at each other, feeling that Gu Chen's question was a bit strange.

Officer Wang also asked him curiously: "Gu Chen, we don't know the deceased from the logistics support department, how do we know how he got scratched? Do you know?"

"I know." Gu Chen didn't shy away from it, and swept up the top of the wound again, and then explained to everyone:

"If I'm not mistaken, the scratch wound on the lower back of the deceased was scratched on the roof of the hotel where we stayed."

"Rooftop?" Upon hearing Gu Chen's words, Lu Weiwei was stunned on the spot, and hurriedly asked Gu Chen:

"Junior Brother Gu, how can you be sure that the scratches on the back of the deceased were left on the roof of the hotel? Have you seen it with your own eyes?"

"No." Gu Chen shook his head.

"Then how did you judge?" Gao Chuanfeng was also curious.

Gu Chen didn't rush to answer, but called Liu Jingru over, and hurriedly asked: "Liu Jingru, do you still remember the first time I drove you back to work?"

"Remember, what's wrong?" Liu Jingru was puzzled.

Gu Chen said again: "At that time, you happened to meet a member of the Pengcheng Club, so you were busy with the matchmaking. When you returned, I was nowhere to be seen. Do you remember?"

According to Gu Chen's reminder, Liu Jingru tried to think back for a few seconds, and then said: "I remembered, you said you saw someone fighting on the rooftop, so you ran over to deal with it."

"At that time, I was waiting for you by your car after I finished handling the registration of these club pilots. At that time, you also came down from the roof and explained to me, that's it."

"It seems that you remember it very clearly." Seeing that Liu Jingru still remembered these things, Gu Chen simply explained to everyone:

"It happened like this at the time. Originally, I was going to send Liu Jingru back to the TV station, but on the way she met some club pilots who came to register, so she went to help, and I waited for her in the hotel's open-air parking lot."

"But then I found out that there seemed to be two black shadows pushing and shoving at the edge of the hotel roof."

"And one of the black shadows was directly strangled by another person, and his whole body was completely suppressed by the railing of the hotel's rooftop guardrail."

"It seems that the other party will be pushed off the roof at any time. At that time, I yelled loudly and warned the other party with a bright flashlight, which made the other party give up the fight."

"What else?" Since Gu Chen didn't talk about it in detail with himself, Gao Chuanfeng was also dumbfounded at the moment, and asked Gu Chen again:

"But what does that have to do with the dead?"

"Of course it's related." Gu Chen swept up the deceased's shirt again, pointed at the deceased's back and said:

"The scratches on the back of the deceased were actually left on the roof, and if I guessed correctly, he should be the black shadow that was suppressed on the guardrail."

"Since I have been to the rooftop scene, I can probably also visually determine the height of the rooftop guardrail and the height of the deceased."

"It can be said that at that time, the deceased was suppressed on the roof, and his lower back was also rubbed against the rusty steel guardrail, which cut the skin of his lower back."

"So that's the case?" Hearing what Gu Chen said, Lu Weiwei suddenly realized, and hurriedly asked Gu Chen:

"Then Junior Brother Gu went to the rooftop upstairs of the hotel at that time, did you find any fighters?"

Originally, I wanted to ask something about the rooftop of the hotel that night, but Gu Chen shook his head and directly denied:

"The situation was urgent at the time, and I was also afraid that the two of them would play for real on the rooftop. After all, in that situation, as long as the other party exerted a little force."

"I dare say that the deceased now was very likely to be pushed off the roof and fell to his death."

"But when I ran all the way and rushed to the roof, I found that the roof was empty, and there was no one."

After a pause, Gu Chen also said helplessly: "So I was very curious at the time, where did these two go? I even searched the scene, but I didn't find anything in the end."

"Wait." As soon as Gu Chen finished speaking, Police Officer Wang interrupted:

"Gu Chen, you mean, you were in the hotel's open-air parking lot and stopped a brawl on the rooftop?"

"Then when you went to check the situation, the other party disappeared, right?"

"Yes." Gu Chen nodded in agreement.

"Could it be that the murderer was the black shadow who wanted to push the deceased down the stairs at that time?" Officer Wang asked again.

Gu Chen nodded: "I thought so too, so if I didn't stop it at that time, I guess there would be an accident."

"Because the black shadow who was suppressed at that time was already lying on his back on the roof railing."

"The roof guardrail is not high, and there is a drainage ditch at the corner, so by calculation, the rusty steel guardrail should be on the lower back of the deceased."

"So, the scratch wound on the lower back of the deceased was scratched on the roof that day?" According to Gu Chen's reminder, Lu Weiwei seemed to know the ins and outs of the matter.

But Gu Chen didn't say it to death, and said slowly: "Although I haven't verified it yet, there are nine out of ten that I can't be wrong."

"Because I had rushed to the rooftop at the fastest speed at that time, logically speaking, the opponent's evacuation time was not fast."

"But no matter how I search, I can't find any trace of the other party. It is conceivable that the other party knows the structure of the hotel very well."

"So at that time, I felt that these two people might be staying in the hotel, but because of the busy work at the time, I couldn't find the person involved, so I didn't pay much attention to this matter."

Looking down at the brain-cracked corpse, Gu Chen also shook his head helplessly: "But I never thought that the accident that didn't happen last time happened here unexpectedly."

"I see." Hearing what Gu Chen said, Liu Jingru who was on the side also trembled and said:

"The person who tried to push him upstairs that night may be the real murderer."

"However, at the scene here, so many of our eyes are here. If he was really designed to be killed by the murderer, how did the murderer escape? Could the murderer be able to fly over the wall?"

Liu Jingru's question made everyone ponder once again.

Indeed, Gu Chen's reasonable reasoning has already classified the death from accidental death to homicide.

Moreover, judging from the situation at the scene, all the conditions were met to commit suicide.

But how did the murderer leave the scene after committing the crime? At this point, it seems to have gone beyond physical cognition.

Seeing that everyone has no idea yet, Gao Chuanfeng quickly suggested: "How about I take the corpse back first?"

"Yes." Gu Chen nodded acquiescingly, and repeatedly urged: "Be sure to check carefully."

"No problem. In addition, after you confirm the identity information of the deceased, send it to me as soon as possible." Gao Chuanfeng said.

"Understood." Gu Chen nodded in agreement.

After carrying the corpse into the body bag, two forensic assistants began to transport the corpse to the vehicle. Gao Chuanfeng also pedaled away after exchanging a few words with Gu Chen at the scene.

After that, Gu Chen asked Liu Jingru to gather all the staff and professional pilots who were staying at the scene in an open space in the abandoned steel factory.

Gu Chen stood on a high ground, turned on the law enforcement recorder, and asked everyone: "Who is the colleague of the deceased?"

The voice fell, and the scene suddenly became quiet.

A few men in work vests standing in the corner looked at each other before taking the initiative to step forward together.

"Comrade policeman, we are his colleagues." A tall and thin man standing in the front row said.

Gu Chen stared at him, and continued to ask: "Then what's his name?"

"Liao Jun." The tall and thin man replied.

"Liao Jun and you have always been colleagues in the logistics department, right?" Gu Chen asked again.

But the tall and thin man shook his head and explained: "Although Liao Jun and we both belong to the logistics support department now, he is a local, and we are all from other places."

"I was invited by the organizing committee, so I came to Jiangnan City temporarily to form the logistics support department."

"But Liao Jun is a local, and many things can be coordinated, so he was also temporarily incorporated into our logistics support department."

"That is to say, you were not familiar with this Liao Jun before?" Lu Weiwei also asked rhetorically based on the tall and thin man's words.

The tall and thin man didn't deny it, just nodded and said, "That's right, I don't know him very well. We only started working with him after we came here."

"Then, does anyone know if this man named Liao Jun has offended anyone recently?" Officer Wang also asked.

But after everyone looked at each other, they seemed to fall into silence.

Officer Wang was very embarrassed, and reminded him again: "Doesn't anyone know?"

"Comrade policeman." Just as Officer Wang finished speaking, a fat staff member stood up from the crowd and said:

"This Liao Jun usually doesn't talk to us very much, and we are very familiar with each other."

"Because we were all members of the technical support department in many of the previous sub-stations, so everyone met more and knew each other better."

With a faint sigh, the fat man said again: "But Liao Jun was temporarily added by the organizer, and we don't know much about him..."

"Organiser, why did you invite Liao Jun in?" Gu Chen hurriedly asked again before the fat man finished speaking.

The fat man hesitated, but he said sincerely, "Maybe it's for the convenience of our work in Jiangnan City?"

"After all, this Liao Jun is also very familiar with FPV traversal machines, and also understands the technology in this area."

"I heard from him before that he was one of the first batch of FPV racing players, but due to some other reasons, he didn't stay in this circle in the end, but became a technician."

"Is he also an FPV racer?" Hearing such an answer, Lu Weiwei was also stunned, and quickly turned to glance at Gu Chen.

Gu Chen also continued to ask without hesitation: "So, Liao Jun was arranged to enter the technical support department of this Jiangnan sub-station. In fact, it was the intention of the organizing committee, right?"

"You can put it that way." The fat man nodded in agreement.

"Then what happened to his leg? Is it a congenital disability? Or some other reason?" Gu Chen asked again.

The fat man looked at the companion beside him, and then slowly said: "From what he said, it seems that he was injured by someone."

"Injured by someone?" Lu Weiwei immediately felt that there must be something tricky in it when she heard it, so she hurriedly asked, "Who was injured by him?"

"I... don't know about this." The fat man shook his head and said truthfully:

"He, Liao Jun, never told us about it, and some of us asked him, but he didn't answer."

"But I feel like he was injured by his creditor. After all, he is really good at gambling. During the rest period of our technical support department, he will play cards with us from time to time. He always wants to bet something."

"Anyway, I guess so. This guy seems to be short of money now."

"That's weird." Hearing what the fat man said, Gu Chen suddenly muttered.

You know, if Liao Jun was injured in the leg by the creditor because of the debt, but the creditor didn't need it at all, and it would obviously take a lot of effort to carefully plan this murder.

Moreover, when Liao Jun died, it seemed that the creditor's money was in vain, and a fool would kill Liao Jun when he was in debt.

Therefore, Gu Chen felt that Liao Jun's death did not seem to be directly related to the creditor.

But if this is the case, then who killed Liao Jun?

Gu Chen is very confused now, or in other words, he doesn't know how to investigate at all.

The key is that important clues cannot be grasped.

The scene suddenly fell into anxiety.

Originally, the major clubs came to this place to train, but now someone died unexpectedly in this area, which added a bit of haze to the training atmosphere on site.

"Officer Gu, can we continue to train here?" Zhao Bo, a member of the Rongcheng Cobra Club who had been waiting for a long time, was also anxious at the moment.

Gu Chen shook his head: "At present, we still need to investigate this area further, so this afternoon's training may have to be temporarily cancelled."

"Cancelled? It's a pity, but can we go back?" Another professional pilot from another club asked curiously.

But Gu Chen didn't agree, he just shook his head and denied, "All of you can't leave the scene now."

"Everyone?"

"Can't you leave the scene?"

"Why? We didn't commit a crime, why can't we leave the scene?"

...

Once the complaints started, they basically couldn't stop.

Everyone gathered together and yelled, feeling that it would be impossible to stay at the scene, and it would be impossible not to stay at the scene. It seemed that the police would not lead them into a dead end.

Seeing this, Lu Weiwei also opened her voice and shouted loudly: "Everyone, please be quiet, everyone, can you be quiet?"

As if being overwhelmed by Lu Weiwei's loud scolding, the originally noisy scene gradually became quiet again.

Seeing this situation, Gu Chen took a step forward and explained to everyone: "I understand everyone's mood at the moment, but why don't I hope you all can start training as soon as possible?"

"But the situation has changed now." Pointing to the location of Liao Jun's accident just now, Gu Chen said again: "Liao Jun of the Logistics Support Department died unexpectedly in this area just now."

"And we also inspected the scene and suspected that the deceased, Liao Jun, was killed by homicide."

"He...he killed?"

"No way? Wasn't he killed by a falling object? There's no one up there?

"Yeah, without the murderer's death, can this be called murder? At most, it's an accident, right?"

...

As soon as Gu Chen finished speaking, the scene became noisy.

Everyone has seen the scene where Liao Jun was hit in the forehead by a falling object just now, and then died, and even had his brain burst.

Many people still have lingering fears, and have not even recovered from the tense atmosphere just now.

But now, Gu Chen gave a reason for committing suicide, which inevitably caused everyone present to panic.

Seeing that everyone was still noisy, Gu Chen simply explained to everyone:

"Be quiet, everyone. I also went to the site to investigate the scene just now. I came to the conclusion that the long steel plate that fell from above was deliberately placed in the corner."

"The purpose is to create this murder accident."

As soon as Gu Chen finished speaking, the scene was full of noise again.

"It was put on it? That's what the murderer put on it."

"But where is the murderer? He flew away? Or is it among us?"

"That's right, when Liao Jun was crushed to death, we all rushed there immediately, and we didn't see anyone else at the scene."

"Yes, we all rushed over when we heard the screams. Where did the murderer come from? It's too late to escape, right? What's more, with so many eyes staring at the scene, how could the murderer escape?"

...

Everyone was chattering, and it seemed that they all had opinions on Gu Chen's statement.

But Gu Chen didn't care, and said truthfully: "Judging from the traces at the scene, there was indeed someone who deliberately designed this accident."

After the words fell, Gu Chen continued to remind: "We paid special attention to that long steel plate when we were inspecting it just now."

"The length of the long steel plate is about one meter, but at the upper position, we found many interesting situations."

Seeing that everyone is not making noise at the moment, just looking at Gu Chen quietly, wanting to get an answer, Gu Chen adjusted his breathing and continued to explain:

"Judging from the rubbing marks above, this long steel plate was once placed in the inner two-thirds position."

"That is to say, the long steel plate about one meter long is sixty to seventy centimeters long, and it is inside the corner."

"As for this long steel plate, you should have seen it just now, right? It's very heavy, very heavy."

"If the steel plate is based on its own weight, it is obvious that it does not have the conditions to fall."

"The only thing that can meet the falling requirements is to ensure that half of the long steel plate, or even more, is in the air."

Taking a deep breath, Gu Chen continued to explain: "Only in this way can the long steel plate fall from the sky due to the loss of balance at the support point."

"Officer Gu." After thinking for a while, a young pilot stood up and asked:

"According to what you said, there are indeed friction marks on it, and can it prove that what you said is true?"

"That's right." Gu Chen nodded and admitted.

"I also think it's a bit strange." The young professional Ai nodded silently, and also echoed:

"After all, who would be bored enough to put this long steel plate in a dangerous position on top?"

"If you want to say that it was welded to death before, it is reasonable, but this is an independent long steel plate, so it cannot be justified."

Looking up at Gu Chen, the young flying hand continued: "So, I also feel that this should be the murderer's intentional statement, but one thing is not clear."

"Tell me." Seeing the other party questioning, Gu Chen stretched out his hand and said.

The young pilot hesitated for a few seconds, then suddenly raised his head and said, "That is, how did the murderer accurately judge that Liao Jun will definitely go to that area?"

"Besides, just when Liao Jun passed through that passage, did the long steel plate just fall? This seems to be a matter of timing, right?"

"Yeah, why didn't the long steel plates fall sooner or later, and the pieces fell when Liao Jun passed by here? Could it be that the steel plates have eyes?"

Being casually mentioned by a staff member, Gu Chen's eyes suddenly lit up, as if he remembered something?

So after a short period of contemplation, Gu Chen also hurriedly replied: "You want to know why? I can tell you, because the murderer placed a gold-plated gold ingot at the scene."

"If you don't pay attention, you really think it's a piece of gold."

"So, it was because this gold-plated gold ingot was directly below the place where the incident happened, so when Liao Jun came here, he subconsciously stopped, picked up the gold ingot on the ground, and checked it out. .”

Taking a deep breath and trying to calm down, Gu Chen said again: "But it was because of this little time that the murderer accurately grasped the opportunity, so the long steel plate that had been prepared on top suddenly fell and was directly crushed to death. Liao Jun who was looking at the gold-plated gold ingots."

"what?"

"So this is ah?"

"Is it the fault of that gold ingot?"

...

Hearing what Gu Chen said, the scene became lively again.

Everyone seemed to be quite frightened by what happened one after another at the scene.

In particular, many people did see the police put a gold ingot into the evidence bag just now, which seems to verify the previous statement.

But Zhao Bo was still puzzled and asked: "Officer Gu, since this is the case, how did the murderer do it, and all his actions flow smoothly?"

"After all, there's no murderer up there, so it's impossible for the murderer to disappear, right? Could the murderer still be able to move around at will?"

"You're right." Hearing what Zhao Bo said, Gu Chen became more convinced immediately, it seemed that the murderer was hiding among these people.

But Gu Chen doesn't have enough evidence yet, so he can only say roughly: "You asked me just now, how did the murderer know that Liao Jun would appear at the scene, and he would appear there exactly, waiting to be killed by himself?"

"That's right, the murderer may have clairvoyance, and has seen all this for a long time. Although the technique is clever, I believe that the murderer will not escape from this area no matter what."

Looking around with sharp eyes, Gu Chen continued to speak slowly: "Because this abandoned steel factory is far from the main road."

"If the murderer wants to commit murder and hurt people in this area, he will definitely not go far, and maybe he will be among you people."

"Because there is no one else around except you."

Gu Chen's words immediately brought the tense atmosphere of the scene to its peak.

After hearing what Gu Chen said, everyone looked at each other again, as if the person standing beside them was the real murderer.

In an instant, everyone was no longer crowded together, but deliberately kept a distance from each other.

Liu Jingru looked anxious, and also asked Gu Chen: "Senior Gu Chen, what you said seems to make sense."

"If the murderer is hiding nearby, it is obvious that he should be among our group of people, but how did the murderer manage to escape the golden cicada's shell? How did the murderer hit Liao Jun accurately with the long steel plate placed on it? ?”

"Don't worry, please give us the police some time, I believe, there will be a result soon." Gu Chen comforted everyone for the time being, and then said:

"However, before that, all of you can't leave the scene, and you must stay here honestly."

"Wait for our police to collect the evidence, and then I will tell you who the murderer is?"

"Yes." Hearing what Gu Chen said, Liu Jingru, who was in charge of everyone's work, immediately turned around and appealed to everyone:

"Please trust the police, just be patient, stay where you are and don't wander around."

"In addition, everyone looks at each other and doesn't let each other out of their sight."

"If you want to go to the bathroom, it's best to go in groups of two or three, and try to keep the other person in your line of sight."

Taking a deep breath, Liu Jingru felt that her throat was about to burst, and she continued to exhort:

"At this critical time, please cooperate. The murderer may be hiding here. As long as the police can find the real murderer, then we all don't have to worry about it, okay?"

Since these days of training and various docking work are all handled by Liu Jingru, many club members are also very familiar with Liu Jingru.

Therefore, when Liu Jingru appealed here, although everyone was a little unhappy, they still reluctantly agreed.

"That's fine." Zhao Bo was the first to stand up and said: "Since Liu Jingru has said so, then we all listen to her, stay here, and cooperate with the police in handling the case. Everyone should not leave at will, and the police must find her. until the murderer."

"Yes, everyone listens to the police." As soon as Zhao Bo's voice fell, Xu Yang, who was always not good at speaking, immediately joined the team of maintaining order.

Everyone said that they can compromise.

In an instant, the noisy crowd also began to cooperate with the police.

Yuan Shasha, who was standing at the outermost edge, was still sticking to the cordon, trying not to let anyone go out from here.

Seeing that the emotions of the people at the scene had been soothed, Gu Chen took Lu Weiwei and Police Officer Wang back to the scene again.

Police officer Wang followed behind Gu Chen, also absent-mindedly said: "Gu Chen, is your story reliable? The murderer is really at the scene?"

"That's right." Gu Chen said as he walked, "If Liao Jun can be accurately killed here, there is only one possibility. The murderer is hiding nearby, but we have not discovered it."

"But for now, I need some validation."

"Junior Brother Gu." Hearing what Gu Chen said, Lu Weiwei, who could understand Gu Chen's inner OS, asked him with a smile on her face, "Do you already know something?"

"That's right." Gu Chen walked to the place where the incident happened just now, and said slowly:

"Among these people just now, some people questioned why the murderer could be prepared to find out that Liao Jun came to this narrow passage as if he had a pair of eyes? And you look at the surrounding environment."

In the middle of speaking, Gu Chen suddenly reminded again, asking Lu Weiwei and Officer Wang to observe the surrounding environment.

Officer Wang nodded silently: "This place is indeed remote, and it is located in an abandoned steel factory."

"And this area is even more hidden. Both sides are covered with weeds, and even the concrete road in the middle is only one meter wide."

"If Liao Jun came here to survey the terrain, the murderer must have relevant guidance nearby."

"In other words, if Liao Jun walks here, he can also be within the sight of the murderer."

Seeing that Police Officer Wang said the truth, Lu Weiwei also asked him curiously: "But Old Wang, it's true to hear what you said, but how did the murderer get off the long steel plate on top?"

"After all, even if the murderer could see Liao Jun coming to the place where the incident happened, how did the murderer make the steel plate fall off?"

"Uh!" After Lu Weiwei said this, Police Officer Wang immediately fell into a dead end, and waved his hands and said, "I don't know about this for the time being."

"Senior Brother Wang, Senior Sister Lu." Seeing that the thinking of the two partners had fallen into a dead end, Gu Chen also reminded:

"You forgot? What is our game this time?"

"This match?" Officer Wang stared blankly.

"FPV traversing machine racing competition." Lu Weiwei also casually echoed Gu Chen's prompt.

But as soon as the words fell, Lu Weiwei suddenly thought of something? Then he said: "I see, the murderer is using the perspective of the camera of the traversing machine to observe Liao Jun's every move?"

"Senior Sister Lu, please continue." Seeing that Lu Weiwei seemed to be enlightened, Gu Chen continued to stretch out his hand and said.

Lu Weiwei pondered briefly for a few seconds, and then said: "The murderer not only used the FPV traversing machine to observe from the perspective, did the long steel plate on it also fall with the help of the traversing machine?"

As soon as Lu Weiwei finished speaking, Gu Chen snapped his fingers and said, "Senior Sister Lu, what you said is exactly what I need."

"My idea is that the murderer may be using the traversing machine. Not only can he remotely control the traversing machine to observe from a distance, but he can also use the traversing machine to activate related settings to make the steel plate fall accurately."

"The crossing machine made the long steel plate fall?" Listening to Gu Chen's words, Officer Wang became more and more confused, and said involuntarily:

"Gu Chen, why can't I understand? How does this work?"

"The reason is very simple." Gu Chen raised his head and looked at the protruding part that he was inspecting just now, and said indifferently:

"If you want this long steel plate to fall freely, several conditions must be met."

"The first thing should be to ensure that at least half of the long steel plate, or slightly less than half of it, is on the periphery of the corner."

"Because in this way, the long steel plate will inevitably be in a crumbling state."

"Secondly, a boost is needed, which is to increase the gravity on the outside of the long steel plate, causing the long steel plate to lose its support balance, so it tilts outward, and finally falls freely, hitting Liao Jun at the bottom."

"It seems to make sense." Hearing what Gu Chen said, Lu Weiwei immediately felt terrified.

But Gu Chen interrupted and said: "Don't worry, this is only one aspect, let the long steel plate fall, increase the weight of the exposed parts, cause the suspended long steel plate to lose balance, and free fall can occur."

"But there is another way, which is to increase the warpage inside the corner, that is, except for the exposed part, the inner part has an obvious prying, which causes the support point to lose its balance. It can also make the long steel plate fall quickly."

"That's right." Hearing what Gu Chen said, Police Officer Wang immediately picked up a flat brick covered with moss and placed it on the concrete floor in the center.

Afterwards, Police Officer Wang broke off a plant next to him, repaired it into a flat wooden stick, put it on top of the brick, and stretched out his hand and said:

"As the process said, I now treat this wooden stick as a long steel plate that hurts people."

"So now I expose half of it to the outside, and you see, it's in a precarious state."

"That's right." Seeing Officer Wang start the experiment, Gu Chen also nodded slightly.

Then, Police Officer Wang lightly used a downward movement on the top of the wood in the suspended position:

"Look, the wooden stick is out of balance now, and it just fell down."

Returning the stick to the position just now, Police Officer Wang gently pinched the other end of the stick and lifted it up slightly, and the stick fell down again.

"This is the second situation that Gu Chen mentioned. There is an obvious upward movement, which may cause the wooden stick to become unbalanced and fall down."

"Yes." Seeing that Police Officer Wang had explained clearly, Gu Chen couldn't help but say, "This is the problem."

"The murderer can not only use the perspective of the FPV through the camera lens, but also be able to accurately capture the specific location of everyone present within a very long range."

"Thus, the murderer can fully understand the location of Liao Jun at that time through the FPV perspective."

"After discovering that Liao Jun had stepped into the trap designed by himself, and stopped to pick up the gold-plated plastic gold ingot on the ground, this gave the murderer a chance to locate."

After a pause, Gu Chen tried his best to calm down, and then said: "It can be said that this is also the only window for the murderer to kill, and this is the only chance."

"Therefore, the murderer used some simple principles, or used the traversing machine, to press down on the suspended long steel plate, causing the long steel plate to lose its balance and fall."

"Or, at the bottom of the long steel plate, use some small devices to lift it up, which is more secure."

"And once the bottom of the long steel plate is lifted up, it is obvious that the suspended part will show signs of tilting."

"In this way, the long steel plate will fall from a high altitude and hit the target directly as planned in advance."

"That's right, why didn't I think of it?" Hearing what Gu Chen said, Lu Weiwei also snapped her fingers excitedly, and continued to add:

"Besides, the murderer must have visited here before, and must have tried it, so..."

"In this way, the long steel plate must have fallen not once, but twice, or three times, or more times."

"Because only in this way can the accuracy of the falling of the long steel plate be guaranteed, which can fully meet the killing conditions." Gu Chen also added.

When Police Officer Wang heard what the two said, his eyes were startled, and he hurriedly said: "That is to say, the concrete floor in this area will definitely be smashed by long steel plates to make all kinds of potholes?"

"After all, falling from such a high place, the impact can be imagined."

"That's right." Seeing that Police Officer Wang also found a problem, Gu Chen simply pointed out with his feet: "Like here, and here, in this small area around, there are so many smashed cement debris."

"I didn't pay much attention at the time, but now I find that these smashed cement debris just show that the murderer came here beforehand."

"Moreover, after many experiments on it, it was determined that the long steel plate could fall freely, and Liao Jun could be eliminated without anyone noticing, so that all this looked like an accident."

After Gu Chen finished speaking, the scene became quiet again.

Lu Weiwei and Police Officer Wang looked at each other, suddenly feeling a sense of dread.

Lu Weiwei shrank her neck involuntarily, and said in a bad mood: "It seems that the murderer really has some tricks, so if you say that, if someone flew over the time-traveling machine at the scene, it must be the murderer."

"Yes." As soon as Lu Weiwei finished speaking, Gu Chen also agreed and said:

"I heard from Liu Jingru that they have just arrived here, and many of them are surveying the terrain."
