Gunshots rang out.

Duan Chen was right before, none of these security guards were good birds, and each of them had several lives implicated in their hands!

The experimental mice that were sent in by various methods would want to run as long as they were awake, but they were suppressed by these security guards, and then re-injected with anesthetics and test drugs.

Some of those with slightly better resistance, or those with more clever minds, will escape from here, but when they get to the heavily guarded outside, they will still be caught by the security guards, and some will be beaten to death!

For killing, these security guards are no strangers to killing, so they will not be soft, now the four guns are aimed at Duan Chen's head, and they shoot at the same time, if they are replaced by others, the whole head will be blown up, but now, they suddenly found that there was no longer that guy in front of them!

Immediately afterwards, Chang Liang felt a cold wind suddenly appear beside him, and before he could react, the arm holding the gun had been grabbed, and then the muzzle of the gun turned and aimed at the companion next to him, just when he was about to warn him, his fingers trembled, and he had already shot a shot!

The companion on the right side tilted his body and fell directly to the ground, and a bloody hole appeared in his head. Chang Liang's arm didn't put down, the muzzle of the gun turned, his body rotated, and he aimed at another companion, but he heard the other party shouting: "Chang Liang, quickly throw away the gun!"

"It's not ......me," Changliang shouted anxiously, wanting to throw away the pistol, but his fingers kept commanding, and instead he grabbed the pistol tighter, and when the muzzle of the gun was about to be aimed at the head of the companion, the opponent's gun went off first.

"Bang, bang!" Two gunshots rang out at the same time, and Chang Liang and his companions jumped back two steps at the same time, and then shouted and shot at the other party again!

After a burst of gunshots, both of them had already fallen to the ground, their chests already red with blood, and the two of them lost their minds and looked at the sky, their chests rising and falling rapidly, and then gradually slowing down, and finally they were motionless.

"I surrender! I admit defeat!" The security squad leader directly threw away the pistol, knelt on the ground, and cried and said to Duan Chen: "Don't kill me! You can do whatever you want, I will never stop you! Please let me go, those things were forced by those foreigners, I am just a small security guard, insignificant, there is no benefit in killing me, spare me!"

In the blink of an eye, his companion turned into a corpse, and the security squad leader was not stupid, and immediately realized that he had met a powerful person this time, so he immediately made a decision and knelt down to beg for mercy.

Anyway, as long as he can live, he can do anything. This man can do whatever he wants, and he has done his best, and he can't stop it. Naturally, someone will stop him, and he doesn't need to take another life!

Duan Chen just looked at him and smiled slightly, when the security squad leader felt bad and grabbed the pistol again and wanted to fight to the death, he suddenly appeared in front of the security squad leader and slapped the other party's head, and the security squad leader's neck made a crisp click, and the whole head almost retracted into his chest, and the person was also angry on the spot!

Ignoring the corpse at his feet, Duan Chen opened the door of the cleaning room, the driver was standing outside with a card and a set of protective clothing, looking inside from Duan Chen's shoulder, the driver was stupid.

In less than five minutes, eight guards died safely? This person in front of him is really a god-killing person! It's really terrifying!

Now although I don't know if I have made the right bet in this game, but seeing this scene, at least the odds of winning are a little bigger, the driver tried to calm himself down, and said to Duan Chen: "This card can pass through the doors of most of the underground laboratories, this is protective clothing, some rooms need to wear this, the province is eroded by drugs or light radiation!"

Duan Chen thought about it, then took it, put on his clothes on the spot, and said to the driver, "What's your name?"

"Cheng Palace! He Cheng Cheng, the palace of the palace. The driver replied to Duan Chen honestly, pointed to his protective clothing and said, "The map is in the pocket, the road below, I won't accompany you, and the province will drag you down!"

Duan Chen nodded, looked at Cheng Gong and said, "Good name, also a smart person, you are here at the door, I will take you out." But you're going to live until I come out, because I'm not going to take a corpse with me!"

"Okay! I'll work hard!" Cheng Gong knew that this was his only chance to get out of here, so he was also very cautious.

Duan Chen nodded, took out the map and looked at it, buttoned the hat off the protective suit, and walked out of the washing room unhurriedly, going deeper along the corridor.

This laboratory is large and cleverly designed, consisting of multiple independent room modules, in the event of an accident or danger, the originally connected rooms will be quickly separated under human control, forming a separate enclosed room!

I don't think that such a design has an excellent containment effect on the leakage of some toxic gases or drugs, and the greater advantage is that once this place is invaded or discovered, it is completely closed and hidden, even if the police come to search, they can't find anything useful!

Swiping open a door with an access card, Duan Chen walked straight in, and all the staff inside were wearing protective clothing like him, so no one noticed him.

This is a drug laboratory, many people have a variety of glass tubes in front of them, for drug comparison and debugging, Duan Chen noticed that although everyone's protective clothing looks the same, but there are differences, there is a label on the left arm, it is a plastic sticker with a color, his is a yellow bar, there are two people around him, the highest is three, in addition to the yellow bar, or green bar and red bar, each color, is divided into one to three quantities.

"Come here, you idiot, do you know that you are stunned, hurry up and clean this place!" a man with two green bars on his left arm pointed to a medicine stain under his feet and shouted at Duan Chen. There seemed to be a broken medicine bottle, and there were quite a few glass shards next to it.

Duan Chen looked around, made sure that the other party was calling him, and walked over, just about to squat down and pick up the label of the broken bottle to see what kind of medicine it was, the guy with two green bars kicked over, and scolded in his mouth: "You want to die, don't you? Don't you know who wears gloves? How can there be such a stupid guy? Who is he the apprentice?"

A man with three green bars next to him laughed and said: "Old Sun, since he wants to be unlucky, don't stop him, these fools, if they are not taught a lesson, they will not use their brains! Anyway, we also lack guinea pigs here, the more such fools, the better!"

"That's right!" the guy named Lao Sun nodded, and laughed with the three green bars.

Someone has already brought cleaning tools, and it is a person who has only one bar like Duan Chen, but he is a green bar.

The man handed Duan Chen something similar to a small vacuum cleaner, and said in a low voice: "This is the poison of the red-spotted cantharid, with the dose that is now sprinkled on the ground, even the protective clothing can be corroded and penetrated, and your hands will rot at that time! ”

Duan Chen looked at the man's hands, which were a little weird, as if they were much thicker than ordinary people, and was about to ask him, but the man himself said: "I encountered something that I shouldn't have touched last year, so both hands were sawed off and a manipulator was installed, and now I am used to it." You're just here, aren't you? Which master are you from? Forget it, you don't have to answer me, it's not allowed to ask here! I'm just ...... It's just that I'm so bored that I want to talk to others. My name is Cui Hao, what's your name? It doesn't matter if you don't tell me, you must be clever when doing things here, otherwise you may never be able to get out......"

"Bang!" Cui Hao's head was hit hard by a pole, and Lao Sun scolded him: "What are you rambling about here? Do you want to die? Who allowed you to chat here before you finished your work? Do you think we have nothing to do? Waiting for you to clean up these wastes?"

Every time he said a word, the thin metal rod in his hand knocked on Cui Hao's head, and Duan Chen, who was standing next to him, could hear the sound of the metal rod hitting the skull, Cui Hao, who was in pain, trembled all over, hugged his head and begged him for mercy, blood had already flowed out from under the brim of his hat, staining the protective suit red.

"Master, I was wrong, I'll finish the work now, I don't dare!" Cui Hao kept begging for mercy with a crying voice, but he attracted Lao Sun to beat him even harder!

"Why do you dare to hide? Why do you dare to block it? I'll let you block! I'll let you hide! You shit! Fool! If you don't clean up for a day, you're not honest, you can't control your mouth, right? Take off your hat for me!"

"Master......"

"Don't pick it? dare to disobey Lao Tzu's orders? Believe it or not, Lao Tzu will directly whip you to death now?"

With the sound of crying, Cui Hao still took off the hat on his head and protective glasses, revealing his original appearance.

It looks like just a young man in his twenties, but his face is crisscrossed and covered with ugly bumps, but on his head is one wound after another, some of the wounds are bleeding, some of the wounds are bleeding!

Lao Sun grabbed a glass bottle and directly poured the liquid inside on Cui Hao's head, accompanied by a fishy yellow smoke, Cui Hao let out a terrible scream and hugged his head with both hands.

"Don't you like to talk a lot, don't you like to go up there and say bad things about me?

"I don't know what you think you've done?

"Do you know what's the least worth here?

"Do you believe that even if I beat you to death now, no one will hold me accountable?"

"Do you know why? Because I'm an elite and you're just a piece of shit, and I'm a contribution to Tyrone, and you're just a shit! That's the difference between us, you know?"

No one around came out to stop it, as if he was used to the scene in front of him, and even interjected from time to time as if he was watching a lively scene, which was more like teasing, making Lao Sun's torture of Cui Hao even worse.

"Smack!" Just when Lao Sun picked up a bottle of potion and was about to pour it on Cui Hao's head, his wrist was grabbed by a person, and the potion in his hand was snatched away.

"Are you crazy, do you want to die?" Seeing Duan Chen pick up the potion in his hand, looking at the label on it, Lao Sun's eyes hidden under the goggles were full of disbelief. "How dare you, the lowest-ranking handyman, do you want to die?"

It turned out that the protective clothing on his body was worn by the lowest level of people. Duan Chen didn't want to blame Cheng Gong, after all, with his identity, it was impossible to get high-level protective clothing.

Duan Chen didn't really take this level seriously, he just turned his head to look at Lao Sun, and said coldly: "When you put on a piece of clothing, you feel that you are superior to others? Who gave you confidence? He was beaten by you after just saying a few words, who gave you the power?"

"Whose apprentice are you?" The man with the three green bars pointed at Duan Chen with his hand and said, "How long have you been here? Don't you know the rules here? Didn't your master tell you this? What a bold man! Do you know what the consequences will be if you do this?"

Cui Hao was already sitting on the ground with his legs weak, but at this moment he still stretched out his hand and pulled Duan Chen's trouser legs, shook his head and said to him: "Don't, don't offend them like this, they will die, they will die! Thank you, don't worry about me!"

Duan Chen turned his head to look at him and said, "Don't be afraid, I'm here, no one dares to touch you!"
