Cheng Yu has deep sympathy for these test subjects.

Although they themselves are poor and can only live by begging, they can live freely in this world.

But Lawrence changed their fate.

It can be said that when they were brought to this island by Lawrence, they had lost control of their lives, and even worse than death.

In the face of such a person, Cheng Yu will of course be very sympathetic, but it is only sympathetic.

"Don't speak, I have no ill will towards you, it's a mess out there right now, maybe, you can consider escaping by yourself. ”

Cheng Yu is still a little wary of this experimental subject, after all, after Lawrence called his experimental subject, the brains of these people were wantonly destroyed, and Cheng Yu also learned part of the truth before, these people, before installing prosthetics, the first thing to do is to erase their self-will.

Therefore, when Cheng Yu said this, he was holding a gun.

Subject was stunned, but the only thing that appeared in his pupils was a blank look.

He seemed to hesitate for a moment, and then rushed at Cheng Yu regardless of it.

Cheng Yu sighed secretly, raised the AK47 in his hand, and slammed it into the man's head.

With a thud, the man fell to the ground.

Cheng Yu didn't bother to care about him so much, these test subjects certainly deserve sympathy, but Cheng Yu is not the kind of good old man, and he doesn't think about saving these people.

To put it mildly, even if they are rescued, with the current level of brain damage, I am afraid that they will die in a few days.

Cheng Yu turned around and used the ability of the wall-piercing technique again to pass through the room where the test subject was being held.

There was no one in the basement, and Cheng Yu ran in the direction of the gunhouse without hesitation.

Pushing open the door of the gun hangar, Cheng Yu shouted softly inside: "Li Gong......"

Li Dali hid in the innermost part of the gun hangar, where the mortars were covered with tarpaulins, and Li Dali hid between them.

Hearing Cheng Yu's voice, Li Dali walked out of it, holding a pistol trembling in his hand.

finally saw that the person who came was indeed Cheng Yu, and Li Dali lowered the muzzle of the gun in his hand.

Cheng Yu didn't have time to talk to Li Dali more, he directly ordered: "Li Gong, don't hold that pistol, that thing is useless." Come here, these automatic rifles, you can take one and get more bullets......"

As he spoke, Cheng Yu threw Li Dali a backpack and motioned for him to bring more bullets.

Although Li Dali was a little panicked, he still followed Cheng Yu's words and kept stuffing bullets into his bag.

"Mr. Cheng, I don't know how to ...... with a gun"

"There's a safety on the gun, you open it, you put the magazine in, and you see someone, whoever it is, if that person tries to get in the way, you just shoot. Even if you can't hit the opponent, you can form a fire suppression. Don't worry about the rest, just follow me out later. ”

It's not that Cheng Yu is reluctant to exchange a few points for the wall piercing technique, but the wall piercing technique can only carry two things other than body clothes. Cheng Yu is obviously going to carry a gun, so bringing another Li Dali will be the end, whether it is Li Dali or the guns and bullets in his hand, they will be left here.

So, to rush out, you must also walk through the gate.

Cheng Yu also took a lot of magazines himself, put them in his bag, and the AK47 in his hand was hung around his neck, he took two more pistols, brought a few magazines, stuck one of the pistols in his waist, and found a silencer and equipped it on the other pistol.

"Follow me......" Cheng Yu saw that Li Dali was also about to stop, and by the way glanced at the automatic rifle in his hand, which was not bad, Li Dali found the location of the insurance and opened it.

At this time, of course, Cheng Yu will not be in a hurry to exchange Li Dali's firearms skills, ten points a minute, and these points have to be used on the blade.

Although Li Dali was very scared, he knew that this was probably the only chance he could escape, so he still stood firmly behind Cheng Yu.

"Mr. Cheng, I heard a lot of gunshots, were you fighting with them just now? Do you have any other helpers?"

Li Dali heard the gunshots above his head, and he thought that Cheng Yu still had helpers, so he was slightly settled.

Cheng Yu wanted to tell him the truth, but after thinking about it, let him misunderstand, if there is a helper who can make him feel at ease and calm, maybe it is also a good thing.

"Yes, there are still our men up there, mercenaries I hired locally. You don't care so much for a while, you just need to follow me and leave, and you don't have to worry about the others. ”

Li Dali nodded, shook the steel gun in his hand very nervously, and Cheng Yu took him out of the gun hangar.

As soon as the door opened, Cheng Yu heard the sound of chaotic footsteps coming from the corridor outside, and there were at least three or four people, so he immediately exchanged a firearm and rushed out first.

Outside was Andrei's people, and when they saw Cheng Yu, they were also stunned, especially when they saw Cheng Yu being fully armed.

They just raised their hands and wanted to say hello to Cheng Yu, but the pistol in Cheng Yu's hand suddenly erupted with tongues of fire.

With the help of the silencer, the gunfire was very small, just four slight pops, and the four mercenaries in the opposite corridor were stunned by four shots in the head.

In Cheng Yu's mind, four golden numbers of +100 appeared in a row.

Until they were dying, they still hadn't been able to understand why Cheng Yu suddenly shot at them.

Moreover, Andre said that Cheng Yu was locked in his office, why Cheng Yu appeared in the basement again, the answer to this question, they will never have a chance to figure out.

Although it was not the first time that Cheng Yu had killed someone, four shots in a row had exploded the heads of four people, which still made Cheng Yu feel a little disgusted.

The air was filled with the smell of blood, which also made Cheng Yu slightly nauseated.

Cheng Yu quickly overcame this sensory discomfort, turned back to Li Dali and said in a low voice: "Li Gong, follow me." ”

Li Dali was also dumbfounded, as soon as they met, Cheng Yu killed four people in a row, even if he didn't have any understanding of marksmanship, he also knew how difficult it was to shoot his head with one shot, not to mention that in such a short period of time, four shots in a row exploded the heads of four people.

This kind of marksmanship is much more awesome than the Olympic champion, right?

Looking at the dead people on the ground, although they were also a little uncomfortable, but these people were not killed by Li Dali, and Li Dali was not as uncomfortable as Cheng Yu.

Gritting his teeth, Li Dali followed behind Cheng Yu and ran to the stairs with him.

As soon as he stepped up the stairs, Cheng Yu heard the sound of someone opening the secret door above, and without hesitation, he raised the muzzle of the pistol equipped with a silencer in his hand and aimed it at the top.

A dark-skinned guy rushed in, Cheng Yu didn't shoot in a hurry, but shouted softly: "What person?"

The man above was stunned, looked at Cheng Yu with a suspicious face, and said, "Mr. Cheng?"

Cheng Yu snorted and said, "It's me." ”

"Mr. Bill asked me to come to you, he regrets it now, he shouldn't have left you here alone, he didn't expect that those miscellaneous mercenaries would have already had the intention of killing him. Mr. Cheng, hurry up and come with me. ”

Cheng Yu blinked, and said in his heart that this is actually Lawrence's person, this guy can, he can actually break through the defense line of Andre's gang and kill into the experimental building.

Seeing that Cheng Yu seemed to be a little hesitant, the man said anxiously: "Mr. Cheng, quick, we just paid six lives to send me in, just to save you." Don't hesitate any longer, come with me......"

Cheng Yu nodded and said, "Okay." Then he stepped forward, raised his pistol, and, with a pop, fired a shot.

The man was stunned, but he didn't feel the pain of a bullet penetrating into his body, he suddenly looked back, only to see a guy next to him, clutching his throat and falling.

"Uh...... Thank you......" The man was a little ashamed, saying that he was here to save Cheng Yu, but he almost died here, but it was Cheng Yu who saved his life.

"I just found another person here, it seems to be the engineer from China that Mr. Bill said, and I thought about taking him out with me, and I heard Mr. Bill say that this person is very important to him. ”

Cheng Yu stepped forward and said to the person above, which can be regarded as explaining the reason for Li Dali's appearance.

The man was slightly stunned, didn't think much about it, and then pointed at Li Dali and asked, "Are you Li?"

Li Dali looked at Cheng Yu, nodded and said, "It's me." ”

"Great, I was going to look for you, Mr. Bill said, it would be best if I could get you out with me. Hurry up, you two come with me......"

Cheng Yu rushed forward in two steps, the pistol was pinned to the waistband of his trousers, and he picked up the AK47 hanging around his neck.

"Don't worry too much, their people are basically concentrated in the front doorway, and they are fighting Mr. Bill. There is no power in this building. You follow me and go straight upstairs, there is a rope behind the roof, you can go down. ”

"You just came down from the roof?" Cheng Yu cautiously pushed open the door, hid behind the door, and glanced out.

The man nodded and said, "Yes, in order to cover me running to the back of the small building, six of us died. ”

Cheng Yu also nodded and said, "You go out first, I'll cover." ”

The man glanced at Cheng Yu and remembered that he had just shot through that person's throat, and he had a little more trust.

Although Lawrence also told him before, Cheng Yu is an agent, and he is definitely that kind of super agent, whether it is marksmanship or individual attack ability, he is very powerful, he still doesn't believe it. Thinking that the person was shot through the throat by Cheng Yu just now, the man believed it.

Lowering his body, the man rushed out, looked at the corner of the stairs, and said, "It's okay, you follow me." ”

With that, the man rushed straight out.

Cheng Yu also rushed out, followed by Li Dali.

There was really no one in the experimental building, but there were constant gunshots outside the front gate, and there was the sound of grenade explosions from time to time, and the small building also trembled slightly with the explosion of the grenade.

It was only a few steps, and the three of them came to the stairs, and the man said, "Mr. Cheng, you go up first, and I will break last." ”

Cheng Yu nodded, the first to rush up the stairs, and glanced back at Li Dali, Li Dali followed very closely, which was a good reaction.

The man walked backwards, Cheng Yu walked cautiously upwards in front, and the three of them quickly arrived on the second floor.

As soon as he turned the corner from the staircase, Cheng Yu saw two figures, and he hurriedly retracted into it, covering his figure with a wall.

"Are there any of you upstairs?" asked Cheng Yu in a low voice.

The man was stunned for a moment, and hurriedly shook his head and said, "No." ”

Then, the man took the lead, poked his head around the corner, took one look, and said, "Not our people." As he spoke, he took a grenade from his waist and pressed the tension spring with his hand, trying to remove the latch with his teeth.

Cheng Yu hurriedly pressed his hand, although the power of the grenade is not too great, but who knows if it will cause any danger?

He said, "I'll come." ”

After that, Cheng Yu shouted into the corridor: "Who are you?"

The people in the corridor were stunned, looked at each other, pointed the muzzle of the gun in their hands at the corner of the stairs, and said, "Who are you?"

"I'm Cheng!" Cheng Yu didn't mind reporting his name, here, only he, the one neither side would want to kill.

When the two of them heard this, they immediately breathed a sigh of relief and said, "Mr. Cheng, it turned out to be you, we are Andre's people, aren't you in the boss's office?

Cheng Yu walked out of the corner of the stairs, his hands not on the gun, he said: "Someone rushed into that office, but fortunately I reacted quickly and killed him with one shot." I didn't think the office was safe enough, so I saw that there was no one in the hallway, so I went upstairs......"

When the two of them heard this, they immediately nodded and said, "The fire downstairs is quite intense...... Mr. Cheng, you just killed someone?"

"Yes, the man was in a gray military uniform......" he said, the dress of the Lawrence man behind him.

"Damn, I said where did this guy go, I didn't find it after looking for a long time, he actually went downstairs. One of them scolded and scolded, but Cheng Yu had already taken this opportunity to walk towards the two.

"Mr. Cheng, it's not safe upstairs, someone broke through our defense line just now and ran to the back of the laboratory building. I reckon they've already come in, and if you just killed someone, you're even more sure. You'd better go down there. ”

"It's not safer down there than here!" Cheng Yu seemed a little displeased.

The man thought for a moment and said, "Basement, basement is slightly safer......"

"If you want to go, I'm not going anyway. Get out of the way, I'll go over there and see if I can get out of the back of the test building. Cheng Yu strode forward, mainly because these two people had been holding guns all the time, and the muzzles of the guns had never relaxed their vigilance, although Cheng Yu had every shot, he was afraid that it would be too late to kill the two of them, causing one of them to fire regardless of it.

When the time comes, it will be bad to shoot the master indiscriminately and kill the master.

The two looked at each other and didn't know what to do, but Cheng Yu had already walked between the two of them, and with a light push, he passed through the two of them.

After a little hesitation, the two of them decided not to care about Cheng Yu, they wanted to continue the search to see if there were any other people in this building.

Cheng Yu heard the footsteps of the two people, turned his face and saw that the two people had already run towards the corner of the stairs.

Without saying a word, he turned around, pulled out the silencer-equipped pistol from his belt, and shot them at the two men.

The two of them fell to the ground, with a gun hole in the back of their heads, and a blood hole the size of a baby's fist on the front of their faces.

It was another two consecutive +100 golden light numbers, which rose in Cheng Yu's mind.

This point is a bit enjoyable, although the use of firearms has cost six points, and it lasted for more than three minutes, at least more than thirty points have to be subtracted, but in just a while, Cheng Yu has killed seven people, and seven hundred points have been obtained.

"Let's go!" Cheng Yu called softly, and Lawrence's people ran out with Li Dali.

"Where are the ropes you are talking about?" Cheng Yu asked anxiously.

The man ran briskly forward and said, "Follow me." ”

Cheng Yu glanced back at Li Dali, Li Dali's face was already full of horror, his eyes revealed infinite fear, and his legs seemed to be a little weak, but he still forced himself to follow.

The man in front of him, as he ran, said, "It's just ahead, there's a fire escape there, you can climb to the top of the building." ”

Cheng Yu nodded, and said in his heart Since I already know the location of the rope, you are useless.

He raised the muzzle of his pistol and aimed it at the back of the man's head.

After a pop, the man fell forward with a cry of exclamation, "Why?"

From his widening eyes, Cheng Yu saw doubts, until he died, he didn't know why Cheng Yu suddenly attacked him, he came to save Cheng Yu.

800 points!

"Don't be stunned, let's go!" Seeing that Li Dali's eyes were already bloodshot, and the person looked a little stunned, Cheng Yu scolded in a low voice.

Li vigorously shook his head, took two steps in a row, but lost his rhythm and fell to the ground with a pop.

Cheng Yu walked over, grabbed him, and said, "Don't mess up, these people are not good birds, and they deserve to die." Hurry up, our priority is to get out of the mountain. ”

Li Dali, with Cheng Yu's support, finally stood up and stumbled forward with him.

Soon, the two of them saw the fire escape, which was simply a hanging ladder, hanging down the wall from above, and more than half a meter above the ground.

Considering that there might be someone on top, Cheng Yu grabbed the suspension ladder first and climbed it with a slight jump.

"Follow me!" Cheng Yu commanded.

Li vigorously gritted his teeth, hung the automatic rifle around his neck, and then ran two steps, jumped up, and climbed the hanging ladder.

Cheng Yu grabbed the hanging ladder with one hand, but the pistol with the other, and after climbing to the hole above, he poked his head out a little, and saw that there was no one on the roof, so he hurriedly took two steps up and rushed to the rooftop.

turned around and was about to pull Li Dali up, but Li Dali said in horror: "Someone is chasing after you......"

Cheng Yu did not hesitate, exchanged a firearm technique from the system mall, and directly chose to use it, but it acted on Li Dali's body.

"Turn back, shoot ......"

Li Dali was also flustered, but he still firmly grasped the handrail of the suspension ladder with his left hand, reluctantly turned his body, picked up the automatic rifle in his right hand, and pulled the trigger downwards without hesitation.

From the cracks around his body, Cheng Yu saw someone coming up, but he was suppressed by Li Dali's gunfire.

Didn't he miss a hit? Didn't he have a hit rate of more than 90 percent? Li Dali's shuttle, to say the least, had seven or eight bullets, so how could he have missed all of them?

Cheng Yu didn't have time to think about it, grabbed Li Dali's arm and dragged him to the rooftop.

Then, Cheng Yu poked out the muzzle of the gun downward, and he didn't care about it.

Not......

No points!
