Chapter 566

All of a sudden, the scene was quiet. Everyone looked at each other and thought hard.

Indeed, Gu Chen's question made everyone feel that the fire and all kinds of doubts on the scene made this small secret room look extremely strange.

Gu Chen said that these questions, no one can give the exact answer, even the landlord driver master also can not give sufficient reasons.

Lu Weiwei carefully observed the driver's expression changes, and then asked him indifferently: "the layout of your room in this way makes people feel like knowing in advance that this is a flammable room."

"What's more, there's not enough cat food and goldfish for company. It's hard to think about it."

"Coupled with the unexplained fire, it makes me feel that the fire seems to have been premeditated."

"This You can't talk nonsense about it Driver Shifu's eyes were dazed, and quickly retorted: "anyway, I don't know what's going on with all this."

"That is to say, all this is the result of your wife's arrangement?" Gu Chen directly extended the past according to the driver's words.

Because according to Gu Chen's understanding of the scene, it seems that this room and the pet cat are more like a bureau.

Many suspicions confirm that the room seems to be preparing for the fire.

In particular, this hungry pet cat with only skin and bones makes Gu Chen's suspicion of this room lead to high tide.

At the moment, the driver couldn't retort, but after a few seconds of hesitation, he nodded and admitted.

Gu Chen then went to a burned sofa, looked at all kinds of burned wood and sponges, as well as the burnt spring. He wrapped a handful of powder with a paper towel and held it in his hand, and then handed it to the public.

"Look, what is this?"

"Burnt powder?" Xu Zhenggang froze for a moment.

"No, no, it's like lime powder." The fire leader seemed to recognize the substance.

But after Lu Weiwei and Yuan Shasha met face to face, they all turned their eyes to the driver.

The driver's master is not aware of Li, bow his head carefully after a period of careful observation, but suddenly can not understand the appearance of Gu Chen: "police comrade, you don't sell the point."

"I really don't know what this thing is. Now that you say so, I'm just confused."

"You don't have to be confused." Gu Chen held the paper wrapped with powder in front of his eyes and said calmly: "what the fireman said just now is right. This is lime powder, and it has chemical reaction with water."

"Quicklime?" Yuan Shasha was the first to ask.

Lu Weiwei was also dull for a moment, and immediately answered: "quicklime and water, these two things seem to be discussed together as long as they are mentioned."

Gu Chen nodded slightly and asked, "but have you ever thought about why this kind of lime powder is in the room? What does this have to do with fire? "

"Is it the quicklime that reacts with water to cause the fire?" The fireman leader's brow suddenly frowned, which seemed to be a little interesting.

If we say Gu Chen's guidance, we can't grasp the key point of the cause of the fire.

Now it seems that Gu Chen has given a material that is quite close to the truth.

Xu Zhenggang frowned, looked at Gu Chen and asked, "I said Gu Chen, there is lime powder in this room for no reason. Is it estimated that someone put it here?"

"Is that worth saying?" Gu Chen looked at the driver's master, then turned his eyes to the security guard and Lu Weiwei of Kaitian property, and said calmly:

"just now, my colleague Xiao Yuan has investigated and monitored with the property manager and confirmed that no stranger has sneaked into the villa these days.

Then there is only one possibility. The lime powder is put here by the driver's wife

"Why what? My wife did it? " The driver was suddenly stunned and didn't respond for half a day.

"Yes Gu Chen looks at the driver's master, and his expression is obviously not as confused as before.

If we can find this evidence, we can say that Gu Chen probably knows the answer in his mind.

"Brother Gu." Lu Weiwei thought of this place and felt that it seemed a little simple. She could not help saying, "according to your meaning, with this thing, the source of the fire can be found, that is, quicklime and water, right?"

"Quicklime and water? Is it so good? " Property security listen to Lu Weiwei's words, the whole person is also with doubts: "how do I feel that only a lot of heat will be released, but ignite objects, is there such a situation?

"Yes, of course." Gu Chen is also indifferent with a smile: "it mainly depends on whether the temperature it produces can reach the ignition point of the object. If it can, it can ignite the object."

All of a sudden, the scene was quiet, and everyone turned their eyes to the lime residue beside the sofa.

Yuan Shasha and firefighters squatted down to check the amount of lime powder in the room.

"Elder martial brother Gu." Yuan Shasha looked back at Gu Chen and said, "in terms of the amount on the spot, can we really ignite objects?"Gu Chen nodded and said, "yes, because the main component of quicklime is calcium oxide. Its shape is white solid and fire resistant."

"But when it reacts with water, it releases a lot of heat or absorbs moisture from the moist air."

"What's more, after adding water to quicklime, you can see that the whole water boils immediately, and a lot of steam is emitted, which generates a lot of heat, and the temperature is also very high."

Seeing everyone's eyes converging on him, Gu Chen said again, "do you know? In fact, many people use the process of adding water to quicklime to generate a lot of heat. They put eggs in it and boil them with lime

"But usually, when the eggs are taken out, the whole eggs are already ripe."

"And this kind of phenomenon is very easy to see in building houses or construction sites in rural areas."

"This way of heating is a more environmentally friendly way, because in the whole process, except for heat release, no other harmful substances will be produced, and energy is not wasted."

The fire brigade leader nodded: "listen to you say that, but there is some truth. I have seen before, using the process of adding water into quicklime to generate a lot of heat, and putting eggs into it, the temperature is really high."

Listening to the fire brigade leader's words, Gu Chen suddenly squatted down, picked up a broken stick from the ground and walked to the wall.

Gu Chen wrote the chemical formula "Cao + H2O = Ca (OH) 2" for the reaction of quicklime and water on the wall.

Then he turned to the crowd and said, "in fact, there are two reactions. One is to pour water into quicklime powder, and the other is to put quicklime into water."

"Ha ha." The property manager could not help laughing, but also saw the people staring at him with strange eyes. He then said with a cool smile: "I said that the police comrade, this Isn't it all the reaction of water and quicklime? Isn't it all the same who joins? "

"You're wrong if you think it's the same." Gu Chen also looked at the formula on the wall and said faintly: "just like the first reaction phenomenon, the water slowly boils and evaporates to dryness, and in the middle of it, it will become gray and turbid. At this time, all the water fully reacts."

"Well What about the second phenomenon? " Xu Zhenggang, holding his chin in his arms, suddenly felt that he was a learning slag.

"The second kind..." Gu Chen looked at everyone and said, "the second phenomenon is that the lime dissolves gradually and generates heat, and then all the quicklime will fully react."

After picking up the black stick in his hand, Gu Chen drew a circle of "Ca (OH) 2". Then he said, "this is the chemical element after reaction, which is a strong electrolyte, but the solubility is not so good. It should be considered as slightly soluble, which will lead to the difference between the above phenomena."

"If the two are strictly equal and fully reacted at the same time, the phenomenon is close to the first case."

"And the reactants in my hands are more like pouring water into quicklime."

"To reach the ignition point of an object, it depends mainly on the temperature it produces. If it can, it can ignite the object."

"Wait a minute." The fire brigade leader suddenly interrupted Gu Chen's words. He looked at the blackened walls around him and said after looking around for a week, "so, this is the real cause of the fire, because the water is introduced into the quicklime, which produces a lot of temperature and releases heat."

"And when it reaches the ignition point of the object, it will ignite the surrounding flammable materials, and then cause the fire."

After integrating these things, the fireman leader looked at Gu Chen and said with a smile: "police brother, I didn't expect you can understand so much, but the problem is that if the quicklime is prepared by the owner's wife, he has already prepared it."

"But why did the fire break out today? You know, his wife and children have been away from home for a week, and it's impossible to do this. "

Gu Chen nodded slightly, then looked at the dead cat body and said, "the driver's family did leave for a week, but I didn't say that his family did this chemical reaction!"

"It wasn't his family, was it..." Lu Weiwei, who looked at the dead cat's body, doubted and said, "is it the cat that did it?"

"That's right." Gu Chen answered directly, then pointed to the dead cat's body and said, "this fire is really caused by this cat."

"But it is not voluntary. After being manipulated, it becomes a ghost for no reason after it has been manipulated and the evidence that the operator is not at the scene, because all this is the layout of the driver's wife."

"I My wife The driver Shifu shook his head in fear, but also quickly retorted: "how can you say that? What does this have to do with my wife? "

"And how did you say that this cat was the one who caused the fire?"

"You want to know?" Asked Gu Chen.

The driver nodded hard: "I really want to know. At least we have to find out why my house suddenly lights up. At least how does the water and quicklime react suddenly?"

"It's because of cat food." Gu Chen pointed at the dead cat's body with Ji O and said, "because when your wife was preparing cat food, she didn't prepare the amount for about ten days. It was likely that it was only three or four days.""So the kitten is hungry after eating all the cat food, so it's targeting the goldfish."

"Yes." Lu Weiwei picked up the pieces of the fish tank on the ground, and then said with surprise: "this may have been filled with goldfish, but now the goldfish are gone, it is obviously eaten by the cat."

"But if there is no source of fire in the room, there is no sign of warm electricity, the gas switch is closed, and there is no time ignition device, the fire can only be done by this cat."

Looking at the bookshelf which had been burned down, Lu Weiwei said with a smile: "if I'm not wrong, the goldfish jar must have been on the top of the bookshelf before."

"When the kitten eats up the small amount of food given to it, it is so hungry that it will go to grab the fish tank on the shelf."

Lu Weiwei said here, Yuan Shasha also quickly answered the words: "so, the final result is that the fish tank fell down and poured on the quicklime."

"Quicklime reacts with water to ripen lime, and the heat released in this process ignites books on the shelves and the combustibles around them."

"That's right." Gu Chen snapped his fingers and said with a happy smile: "so the result is that although the kitten ate the goldfish in the fish tank, it can also pour the water in the fish tank on the quicklime, which caused the fire."

"And this house is just closed. After eating the goldfish, the kitten can't escape from the room even though it is full of food. Therefore, it suffocates and then burns its hair in the fire. That's what it is now."

Looking at the corpse of the dead cat at his feet, Gu Chen said again: "if I guess correctly, the goldfish eaten into the cat's stomach should not have been digested. If I want to confirm whether what I said is true or not, as long as I open the cat's stomach, you can know whether it is true or not."

One side of the fire brigade leader looked at Gu Chen, immediately from his own body, took out a multi-functional saber, and then squatted down to give birth to the cat's belly, with the edge of the knife.

Before long, the fireman leader found the remains of goldfish in the cat's stomach.

"Ha ha." The fireman leader turned to look at Gu Chen and said with a cool smile: "police brother, you're right. These goldfish have just been eaten into the cat's stomach and haven't been digested yet."

"My God." One side of Xu Zhenggang, also see Gu Chen according to the scene of a small amount of evidence, restore everything happened in the room, the whole person is also dull for a while.

Now his eyes on Gu Chen have changed, and the whole person can't help but say: "I said Gu Chen, you can use this thing to infer such accurate results. You What the hell is in your head? "

Gu Chen is also indifferent smile: "usually use more brain, when you stay in this suspicious environment for a long time, you will also have this keen observation, it is just a professional habit."

"Police brother." At this moment, the fire brigade leader who put away the multi-functional saber also couldn't help but give a thumbs up and said: "you've let me have a long experience today, so you can reason it out. I feel that everything here can't be concealed from your eyes. You are really a bit fierce."

"Ha ha." Listening to the fireman leader's praise of Gu Chen, Lu Weiwei was not only happy, but also angry:

"you said this is a bit interesting, and you don't ask. My younger brother Gu is in Furong Branch of Jiangnan City. Who doesn't say he's powerful? It's a big surprise. "

"Is that my ignorance?" The fire brigade leader is also smiling.

However, while everyone was silent and trying to solve the mystery of the fire, Gu Chen suddenly turned his eyes to the driver and asked him:

"the fact is very clear. If your wife left the villa last, your wife set the fire."

Looking up and down at the driver's master, Gu Chen doubted again: "is it You and your wife conspired to set it off? "

"Absolutely Absolutely not. " He was also frightened by Gu Chen's words. The driver's master was stunned and quickly explained to himself, "I don't know what my wife has done at home."

"You know, this is my home. Why should I burn down my own house? Am I sick? "

"Gu Chen." Xu Zhenggang looked at him and quietly reminded him, "what he said is right. Who is so wayward and has nothing to do with burning his own house to play?"

Gu Chen hesitated for a few seconds and quickly said to the driver: "in this way, you can call right now and ask your wife to go home quickly. After you come back, you can go directly to Furong Branch office."

"And now you have to go to Furong Branch office with us to clarify the situation here. We need to sort out the detailed investigation report."

"But I've got to run tonight." Said the driver.

Lu Weiwei also did not have a good airway: "I said you are really, the house has been burned, you still run didi? It's a serious thing, you know? "

"The good thing is that it only burned your family. If it endangers other residents, how many people will be killed?""It's a felony to deliberately set fire to endanger the safety of other people's lives and property."

Listening to Lu Weiwei's reprimand, the driver's master did not dare to speak. At the moment, he was dizzy and didn't know how to solve the current problem for a long time.

Gu Chen looked at the property manager beside him and said, "in this way, you are responsible for locking up the scene, and don't let anyone enter the room."

"Don't worry about it." The property manager also patted his chest and promised, "I'll go to get some things later and lock up the door."

"Good." Gu Chen nodded, then looked at the driver and said, "master, please drive didi again, and go to the branch office with us."

……

……

It's 10:30 p.m.

Furong Branch, interrogation room one.

After a night of combing, Gu Chen basically recorded the driver's situation completely.

The driver's former name was Xu Youcai, originally a rich name. But now it seems that not only his career has been frustrated, but also his only house has been destroyed by this merciless fire.

All night, Xu Youcai was honest and explained what he knew one by one.

Prove that I really don't know what is the situation of his wife and deliberately create the arson incident.

After being summoned by the police, Xu Youcai's wife, who is also a star night commuter, finally took a taxi to Furong Branch office at 4:00 a.m.

All the way to inquire, wearing a white down coat, slightly gaunt middle-aged woman, this just trotted all the way to the third criminal investigation group.

At the moment, there are only three folding beds open in the office.

Gu Chen, Lu Weiwei and Yuan Shasha are lying there, squinting slightly.

After hearing the knock, Gu opened his eyes slowly and looked up at the visitor.

"Are you?" Gu Chen got up and asked her.

"I'm Xu Youcai's lover. You asked him to call me." The middle-aged woman took the initiative to come forward and said.

"Oh, you sit first." Gu Chen sat up, and then clubbed Lu Weiwei and Yuan Shasha beside him. Only then did they stand up stubbornly.

Later, the middle-aged woman sat in officer Wang's chair, while Lu Weiwei and Yuan Shasha were standing on one side.

After debugging the camera, Gu Chen moved the stool in front of the woman. Then he opened the transcript and said, "let me introduce myself first. I'm Gu Chen from the third criminal investigation group of Furong sub Bureau. This is my colleague Lu Weiwei and this is yuan Shasha."

"Hello."

Lu Weiwei and Yuan Shasha also nodded slightly, which was a simple understanding of middle-aged women.

"Do you know why you were called back?" Gu Chen turned his pen with his right hand and asked.

The middle-aged woman nodded: "yes It's because my house was burned. "

Gu Chen suddenly stopped writing, looked up and said, "what's your name? The ID number is reported.

"Oh, oh, my name is Hao Tong, and the ID card number is..."

Hao Tong is also nervous at the moment. He quickly informs Gu Chen of his personal information.

After recording this, Gu Chen asked: "Ms. Hao, this is the specific situation. Your house suddenly caught fire tonight. After all kinds of fire fighting efforts and tonight's rainstorm, the main building is still preserved."

"But all the interior decorations have been burned, including your cat and the jar of goldfish."

It is also when Gu Chen mentions the cat and goldfish that Hao Tong's eyes are obviously dull for a while, and then he quickly calms down his mood.

Xu tongshao's information is only provided to the driver's home.

In addition, the police summoned him. Therefore, Hao Tong is also a star night journey. He knows nothing about the situation here.

But Gu Chen's deliberate question just now startled her. It seemed that those little nines in her heart were suddenly known.

Listen to Gu Chen's words, Hao Tong also indifferent smile: "hard police comrades, really do not know how to thank you."

"If you really want to thank you, you shouldn't have set that fire." Standing by her side, Lu Weiwei also has no good airway.

Hao Tong was stunned. He did not know how to take a look at everyone. He did not have a good way: "I said police comrade. What do you mean by this? My house has been burned. "

"I know. Of course you don't have to remind me. You set the fire." Lu Weiwei also continued her speech.

"Ha ha." Hao Tong couldn't help laughing. Looking at Yuan Shasha and Gu Chen, he retorted: "police comrade, you Are you mistaken? You said I set the fire? I'm not in Jiangnan. "

"And I also heard my husband call to say that our house is on fire and the house is gone. Let me come back quickly, and I'll come here by night and night."

Looking at Gu Chen's indifferent eyes, Hao Tong said again, "as soon as I get back to Jiangnan City, I'll come to your Furong Branch office. I haven't stopped for a moment. My parents can testify."Gu Chen nodded slightly: "so?"

"So?" Hao Tong looked at Lu Weiwei, but she didn't have a good way: "so this female comrade, regardless of the nature, said that I set the fire. Am I sick? In the evening, I went to Jiangnan City from such a long distance to burn my house to play? "

"And then run back in the starry night, and come back with your fire? Am I sick? "

Just now Lu Weiwei's words made her angry. Hao Tong held her chest with her hands and her head tilted. She wanted to talk with Lu Weiwei.

Lu Weiwei also said with a smile, "so, what's the matter with the quicklime in your closed room?"

Hao Tong's ear says, the whole person expression is dull for a moment, secretly glanced at Lu Weiwei.

"And your cat has been hungry for days, right? You don't have enough cat food. Your cat is hungry, but you put a jar of goldfish on the bookshelf. This is the rhythm that cat food is not enough for goldfish to come together? "

Listening to Lu Weiwei's words, Hao Tong's face was stunned, and Dai Mei frowned: "you What are you talking about? What cat food and lime

"Don't pretend, Hao Tong." Yuan Shasha also looked at Gu Chen beside her and said to Hao Tong, "elder martial brother Gu, I have restored the fire scene according to the scene environment."

"You should know that this cat doesn't have enough cat food at all, so you deliberately put a fish tank with goldfish on the bookshelf. When the cat is hungry, it climbs up the bookshelf, overturns the fish tank, swallows the goldfish into its stomach to satisfy its hunger, which is also when the water in the fish tank is poured on quicklime."

And you don't know what happens to quicklime? It is also because of the release of a large amount of heat, leading to a certain ignition point, ignited this flammable room

"And we have checked that, in addition to a large number of flammable objects beside the bookshelf, the enclosed room is pasted with the same wallpaper, which is the reason why your home was burned down."

"Because from head to toe, it's all your own elaborate plot, right?"

"I..."

Hao Tong suddenly froze.

The way she looked at the three changed.

It was also when Yuan Shasha explained the situation to Hao Tong according to Gu Chen's investigation results, and Hao Tong was shaking with fear.

As if the stars and nights came here, is to convict themselves?

"I Where's my husband? " Hao Tong took out his mobile phone in a panic and shivered: "I I don't want to talk to you. I I'm looking for my husband. I'm going to call him. "

It's also the number Hao Tong has just dialed, but the phone rings from Gu Chen's desk.

Gu Chen also put down his writing pen. Then he took Xu Youcai's mobile phone in his hand and shook it. He said, "don't worry. Your husband Xu Youcai is also staying in Furong Branch office. After you explain clearly, we will arrange you to meet him."

"Why What? " Hao Tong was lying on the chair, and murmured, "you You caught him, too? "

"So Why did you set fire to it? " Gu Chen said.
