Yilin didn't know why the non-existent area in front of him should be named with the letter "s".

But thinking about it is nothing more than catering to the taste of the apostles.

In the eyes of the apostles, "s" always means cow.

Or "secret"

“Super?”

But anyway, there must be a big secret in it.

Otherwise, Yu Meng and Zhao Yulong will not appear here at the same time after being warned by "GM".

"Didi didi -"

Face, fingerprint, password and iris, Yu Meng opened the door with quadruple verification.

"Wheezing -"

On the verification panel of the heavy metal door, the electronic light flickered and the air pressure gushed, and then moved slowly to both sides.

Zhao Yulong suddenly sighed and stopped.

"I... won't go in."

As he spoke, Zhao Yulong subconsciously groped on his body. After groping for a few seconds, I finally found a wrinkled cigarette from my trouser pocket.

Yu Meng's expression was indifferent and looked at Zhao Yulong.

"Didn't you say you quit smoking?"

"Hey, hey, I'm addicted to smoking. Just one, the last one." With a dry smile, Zhao Yulong skillfully lit the cigarette, holding the cigarette's index finger and middle finger, trembling slightly.

Yu Meng didn't say much, so he turned and stepped into the door.

Behind Yu Meng, in the corridor with no end in sight, only Zhao Yulong with a bleak expression and the flickering fire at his fingertips were left.

Yilin followed Yu Meng carefully.

Don't be careless.

Behind the metal door marked "zone s", there is another channel.

On both sides of the channel, after Yu Meng entered, a large amount of gas burst out suddenly.

At first, Yilin's expression was silent, and he subconsciously held his breath in the shadow, but he also reacted a moment later.

——Is this disinfection?

Yu Meng walked through the disinfection channel without expression.

But at the end of the passage, Yu Meng stopped, closed his eyes and said in a cold voice:

"Come out."

“!”

In an instant, a "fault" appeared between Yu Meng's body surface and the "disinfection gas".

"No!"

Yilin suddenly felt that there was a whirling world in front of her eyes.

This is not a pure disinfectant gas!

It's mixed with ether!

Sure enough, there is fraud!

As soon as Yilin bit his tongue, the painful stimulation made Yilin awake for a few minutes in a short time. Fortunately, Yilin knows that Yu Meng is not so easy to deal with. Even if he maintains the two anti sky skills of [shadow killing] and [shadow following], he doesn't dare to relax his vigilance and maintain a state of high concentration.

When the disinfection gas was ejected, although Yilin inhaled a little, the amount was not too much, and the breath was shut in time.

Yu Meng isolated the gas and smiled: "this is a high concentration of ether gas. Anyone who takes a full breath will completely faint. Even the high-level power side apostles."

While talking, Yu Meng quickly pasted it to the wall, leaned against the wall, and swept his cold eyes into the only disinfection channel in front of him.

Yu Meng waited for three minutes.

After the initial dizziness, the discomfort in Yilin's body soon disappeared after a few seconds.

Yu Meng is right.

As long as it's a person, taking a sip may lead to a coma.

Unless it's not human.

Yilin, who lurked silently in the dark, couldn't help but praise his "mixed blood".

In his mixed lineage, he retained most of the characteristics of "Dionysian factor" and had a certain resistance to that mouthful of ether.

After waiting for five minutes, the imaginary "Lurk" did not appear. Yu Meng quietly breathed a sigh of relief and reopened the closed disinfection channel door.

What a sinister woman!

Yilin sighed secretly.

He's figured it out now.

When entering the password at the entrance, there must be two different versions of the password.

Although both versions of passwords can open the access door.

But one of them is the normal opening mode, and the other, like the current situation, is mixed with high concentration of ether in the disinfection gas. If another Apostle who is not vigilant enough and is also good at sneaking comes, it is estimated that he will also be careless and win the Yin move of Yu Meng.

After this brief episode, Yu Meng seemed to be convinced that the intruder in the "GM" warning did not follow her.

"No exceptions."

Yu Meng whispered to the air.

It seems to be Zhao Yulong who is smoking outside the door.

Yu Meng quickly walked into the women's dressing room.

Yilin hesitated for several seconds. In order to avoid losing him, he had to sneak in.

But fortunately.

The embarrassing scene did not appear bloody.

Yu Meng directly put a isolation suit on his body, left the dressing room and walked into the bright and magnificent laboratory.

Seeing that Yu Meng was so cautious, Yilin subconsciously doubted whether there was some terrible virus test in the s area. Once it was leaked, everyone would be finished.

"The transmission mode of the virus is mostly contact transmission, which is transmitted with the respiratory tract. As long as you hold your breath and keep the shadow state, the problem should not be big."

They have all come here. It would be a pity to give up and retreat now.

Yilin believes that there must be something hidden here.

If the mysterious "GM" had not sent a warning of "invaders" to Zhao Yulong and Yu Meng by chance, Yilin might not have found this place.

After all, his original purpose was to borrow a small document from the main computer in area A.

Compared with the secrets hidden in area s, it's not worth mentioning that girls see young women and scallops see lobsters.

Yilin is not usually a gossip person.

But the secret of area s was enough to arouse his curiosity.

Yilin slipped in quietly.

Follow Yu Meng.

Yu Meng is wearing a bloated isolation suit and walks into the room quickly.

Yilin lurked in the shadow and suddenly opened up in front of him.

Just for a moment, Yilin was stiff in place.

Hold your breath for a long time.

Yu Meng has walked to the researcher who is busy in the laboratory and is also wearing isolation clothes and whispered something.

Yilin is no longer in the mood to eavesdrop. What are Yu Meng and the researcher talking about.

Because,

The scene in front of him is enough to explain all the problems.

In the bright underground research institute, there are many transparent life support modules.

There are countless people floating in the green light of the life support cabin.

——A physically disabled person.

Some people have been replaced with metal prostheses.

Some people have changed their eyes into red metal artificial eyes.

Some people's skin festered and writhed painfully in the life support cabin, but they couldn't make any sound.

Some people have only half of their bodies left, and even their internal organs float in the nutrient solution, but the regular undulating chest can prove that they are still alive.

This scene, deja vu.

After two minutes of silence, Yilin also held his breath. After two minutes, Yilin took a deep breath.

"I see."

……

……

an hour later.

Yu Meng skillfully took off his isolation suit.

The contaminated isolation clothes, with an idea from Yu Meng, floated into the special waste box for medical pollution waste.

"How's it going?"

In front of the s area, Zhao Yulong was spraying men's Cologne on his body in a hurry, trying to hide the pungent smell of smoke.

Yu Meng frowned and looked at the flat cigarette butts on the ground without trace, but he didn't say much about it, just shook his head:

"There should be no 'intruder'. I can hardly imagine that someone can avoid our 'perception'. Moreover, I used class B emergency plan in the channel. The concentration of ether is enough to expose any lurk without precaution."

Zhao Yulong breathed a long sigh of relief at the speech.

Yu Meng's frown did not stretch out.

"But I still wonder why, without the so-called 'intruder', that hidden special adviser, who hasn't appeared for so long, he suddenly chose to warn us today. I never think he is really on our 'side'."

Zhao Yulong smiled: "maybe there was, but when we strengthened our guard in the open and in the dark, the other party noticed and cancelled the plan of invasion."

"It's possible." Yu Meng did not deny Zhao Yulong's speculation. From the current situation, Zhao Yulong's speculation is also the most reasonable.

"Let's go."

"However," Yu Meng's eyes twinkled and a cold thought flashed in his eyes: "it's not safe here. We must find a way to evacuate all personnel and 'experimental objects'."

Zhao Yulong smiled bitterly and didn't say much.

To be on the safe side, they searched each area again.

Under the perception of the two spiritual apostles, all the hidden ones will have nowhere to hide.

Although Zhao Yulong and Yu Meng didn't say much next.

In addition to Yu Meng, Zhao Yulong also felt that there was something strange about tonight.

I always think something's wrong.

But for a while and a half, he couldn't say it again.

If something happened in the end, they might not have this "strange" feeling.

But after some tossing, it was safe in the end. This feeling was like a shot with full strength stabbed into the wall, which was very painful.

It was late at night when Zhao Yulong walked out of the scientific research department.

Before leaving, he even checked all the surveillance videos and found nothing unusual.

"Is it really just a false alarm?"

Zhao Yulong wiped the sweating on his forehead in disbelief.

It was late at night.

After saying goodbye to Yu Meng, Zhao Yulong walked alone in the lonely street. He suddenly remembered something. He quickly opened the communication panel. After hesitating for a moment, he still sent a message.

"Yo! What are you doing? Have you experienced the big sword service with local characteristics in cangyang? If you need it, I can introduce it to you privately. Of course, it can't be reimbursed."

"Get out."

More than 2000 kilometers away, Yilin's voice sounded in Zhao Yulong's ear without any delay.

"I'm busy."

"What are you doing?"

"I'm at the last victim's house. What do you say I'm busy with?"

Yilin's voice sounded angry.

Angry?

Just be angry.

Zhao Yulong exchanged greetings again. It seemed that the more Yilin complained and the more unhappy his tone was, the more comfortable he felt. Zhao Yulong had no consciousness of "this psychological state is a little abnormal", and grinned happily.

Afterwards, Zhao Yulong confirmed it to Yuan Zhiye and Wang Bing respectively.

Yilin is indeed in cangyang City, no mistake.

"It seems that it's really none of his business. Besides, he won't come here if he's okay."

Closed his eyes for a while.

Zhao Yulong was very impressed:

"It's really a good employee who works hard!"

……

……

After finishing the call with Zhao Yulong, Yilin looked indifferent and thought about what she had seen in the scientific research department an hour ago.

Unexpectedly, this kind of research is being done in the s area of the scientific research department.

No wonder after copying the Xiao family, there was no more text about the Evangelical Church.

Yu Meng.

Zhao Yulong.

Specific group.

No one is enemy.

Names flashed in Yilin's mind.

Nobody should know about it.

But why did Zhao Yulong hide it from Mo's enemies?

I'm afraid Zhao Yulong will be beaten to death in case Mo's enemy finds out?

The future that Yilin is about to experience seems to be moving towards a completely strange direction after Xiao Yang's death.

Everything has changed.

Not just everything around him.

And the world.

Irene suddenly remembered ulanos's words:

"Since you don't have any concept of the future, it's meaningless for you to ask this question."

Yeah,

meaningless.

wait.

Yilin suddenly moved in his heart.

It seems that in the vague dialogue between Yu Meng and Zhao Yulong, in addition to the secret hidden in area s, they also mentioned one thing.

——"Document d4516".

"It seems that there are more and more troublesome things."

In the dark, Yilin's eyes twinkled and whispered.

After leaving the capital, Yilin directly used reverse transmission and returned to cangyang city from Molly's laboratory without disturbing anyone.

Before leaving, Yilin quietly put the USB flash disk with the relevant data of "Star Steel" under Molly's pillow.

But after tonight, the ownership of Star Steel seems to be less important.

When talking to Zhao Yulong.

Yilin didn't deceive and told the truth.

He did come as fast as he could to the last dead man's house.

In any case, in order not to arouse Zhao Yulong's suspicion, we still have to find a way to solve the "leech Corps serial homicide" in cangyang city.

It can't be solved.

As for everything about the s area on the D4 floor of the scientific research department, Yilin can't sort out his thoughts at present, so he can only put it aside for the time being.

Yilin took a deep breath.

Yu Meng's strength at this time, as he initially guessed, had already broken through the first layer of spiritual lock and reached an extraordinary state.

The "mental power" freely displayed is proof.

Once the spiritual lock is unlocked, "spirit" is no longer invisible and colorless, but evolved into a substantive force.

In silence, Yilin waved his palm in the void, facing the camera at Gao Chengwen's door and slowly swinging to another angle.

After avoiding the line of sight of the camera, Yilin easily entered the deceased's home.

Originally, this time, as an "official", Yilin had full authority to go through normal procedures to enter the scene for investigation. But because he was in a hurry, Yilin didn't bother to let yuan Zhiye apply for relevant procedures. Come here first. Otherwise, Zhao Yulong's words are not right, and Zhao Yulong will inevitably doubt it.

At the moment of entering the house, AI welcome voice sounded, soft lights lit up successively, and classical music played melodiously.

Before ventilation, Yilin clearly smelled that there was a strange and unpleasant smell in the air.

Because in addition to the removal of the body, the scene still maintains the appearance of the deceased before his death and has not been cleaned up.

Twenty minutes later.

Yilin has searched the whole house and found many missing details in the report.

"Knock, knock, knock."

Suddenly.

There was a knock outside the door.

Yilin felt his tentacle sticking out. When he learned that the door was a stranger, he just smiled and opened the door without hesitation.

At the moment of opening the door.

A tall and thin man stood quietly in the dark.

The man was wearing a dark suit with a shirt inside and the top two buttons untied at will. The curly bangs covered the eyebrows and cast a dark shadow over the eyes. He even wore black thin gloves on his hands, which was obviously prepared.

"Yi Lin?"

"Gu Tianqing?"

Just a look in the eyes, they confirmed their identity with each other.

This is the first time that Yilin and Gu Tianqing met in reality after their trial practice in the Caribbean.

And that trial practice was in a special "role-playing" mode. Yilin has never seen Gu Tianqing himself, but the hypocritical smile on the man's face and the faint cold light in his eyes make Yilin quickly confirm Gu Tianqing's identity.

Same.

For Gu Tianqing, Yilin existed as "Elizabeth Lin" in that trial practice. But at first glance, Gu Tianqing also confirmed the identity of Yilin, even without introduction or more words.

At this moment, two men who had intrigued and almost made sparks in the trial practice rarely had the same idea.

——"This fake smile without any sense of disobedience is definitely him and can't be wrong.".

……

They looked at each other and smiled.

The smile is meaningful.

Gu Tianqing stood at the door and smiled gracefully: "don't mean to say 'please come in'?"

"You love to get in."

Yilin turned directly and gave Gu Tianqing a cold back of his head.

“……”

Gu Tianqing's smile froze.

I still went in.

It doesn't matter whether you invite or not.

Gu Tianqing just said it casually.

I didn't expect that Yilin really didn't give face.

"Well, you owe me a big favor."

Yilin emphasized seriously.

Gu Tianqing smiled without denying or admitting. She roundly changed the topic: "my divination is not wrong. The thing I'm looking for is still on my 'friend on the sea'."

"I can only say not."

After Gu Tianqing entered the house, he searched around as fast as he could.

Yilin's eyes flashed.

Gu Tianqing's search route is almost the same as him.

If it wasn't for her own eyes, Yilin even wondered whether Gu Tianqing had secretly seen the top secret information of the special group.

"You are very skilled."

Yilin smiled and broke the silence.

"Average."

Gu Tianqing just came out of the bathroom and answered Yi Lin's words, but she frowned and rubbed her right thumb and index finger. From the gloves he rubbed, some fine powder floated down.

After pondering for a moment, Gu Tianqing looked at Yi Lin's eyes and said with a smile, "you really don't intend to provide any information?"

"Oh, the deceased, male, Gao Chengwen, 35 years old, works in a canned food company, ordinary staff, single and living alone. This is also the eleventh deceased."

"Dead?"

Yilin flicked his finger, a photo developed in advance, whirled and swept towards the valley.

In the picture, it is the picture of the dead.

Top secret.

Gu Tianqing narrowed her eyes slightly, hid the light in her eyes, stared at the picture on her hand for a moment, and then slowly breathed out: "it's a little interesting."

"Isn't it worth it?"

"OK. What do you think of the murderer?"

"Not people."

"Just as I thought." Gu Tianqing blinked and smiled.

“……”

"At the beginning, after investigating the scene, I was not sure, but after seeing the photos of the dead with my own eyes, I was sure."

"Tell me."

Gu Tianqing went to the dead man's bedroom and pointed to the corner near the window.

"The location and posture of the death were outlined by the police. There's no problem. It should be there." Gu Tianqing stepped forward and said, "it can be seen that the deceased should be in a very strong fear before he died."

Yilin said: "well, the design of this kind of window is a safe structure to prevent falling off the building, so it can't jump down. There are traces of forced friction on the edge of the window. The traces are very fresh, which should have happened before death. There are light blood stains on the edge of the window, which should be left by accidentally pinching your fingers when shaking the window."

Gu Tianqing smiled: "when people are in extreme fear, they always subconsciously look for the place where they feel most secure. In this closed room, there are only two places where the dead feel most secure, one is here, the bedroom of the dead, and the other..."

"The only exit." Yilin quickly picked up.

After a moment of silence, Gu Tianqing continued to analyze: "but according to normal circumstances, when a person is facing a crisis, even in great panic, the first thing to think of should be the exit, rather than locking himself in the bedroom."

Yilin: "there is only one possibility. His position at that time and the position of the exit were blocked."

Gu Tianqing raised the photo of the dead in her hand and said with a smile, "let's talk about the cause of death of the dead. This kind of corpse like a 'dried corpse' can only be caused by the rapid loss of water in the body, including blood, in a very short time. It's hard to imagine that the dense wounds on the dead were done by 'humans', more like a creature."

"Leech." Yilin didn't sell off and directly said his speculation.

"Sure enough." Gu Tianqing's eyes flashed slightly and nodded without any surprise: "it's located in the south. The climate is warm and humid. Although it's not an agricultural area and it's not the breeding season for leeches, it makes sense if you consider the influence of 'unusual' factors."

"To sum up, when the dead were alone at home, there were a large number of leeches, an unimaginable number, which was large enough to make the dead's scalp numb. The leech Legion was blocked between the 'dead' and the 'exit', so the dead only had to lock themselves in their room and ask for help."

"But before the death of the deceased, the police did not receive any distress information." Gu Tianqing went to the bedroom door, closed the door, then leaned down to check the gap between the door and the ground without stopping, and continued: "If the deceased thought at the beginning that the bedroom door was enough to resist leeches, he failed in the end. It shows that the time interval between the dead closing the door and the leeches breaking through the door is very short, so short that the deceased has no time to ask for help."

"This also shows that these leeches are like being commanded by someone in the dark. If they are pure soft creatures, they can't have such discipline. They can even change their shape and quickly drill through the gap less than 0.5cm. The picture is a little disgusting."

One by one, they clearly reproduce the various experiences of the deceased before his death.

While saying this, Yilin and Gu Tianqing successively walked out of the dead man's bedroom.

Gu Tianqing said with a smile: "based on these simple clues, I think you should have known through what channels that group of leeches invaded here."

"Well, sewer."

Yilin pointed to the direction of the bathroom and said softly.

It's not difficult.
