Shen Chen didn't know the danger of all this, and they eliminated a few wandering zombies on the way through the laboratory.

The three of them had a bad feeling when they looked at the large hole in front of the corridor, because according to the map indicated, behind the wall was the place where the monitoring room was located.

Walking into the monitoring room, as they expected, this place has been destroyed.

Fragments of monitors were strewn all over the floor, and the monitors on the walls occasionally erupted with sparks caused by short circuits, and even the overhead lights flashed.

Li Bing looked at a corpse on the ground that had been gnawed into white bones, the bones of the rest of the corpse looked quite intact, but his sternum showed a comminuted fracture.

Although it was the impact of great power.

"It seems that there are evolved zombies here, and the level is not low, and the broken bones of this person have at least reached the level of T2." Li Bing said to the two.

Hearing Li Bing's analysis, Shen Chen and Xue Yang were not too surprised. After they saw the wall destroyed, they had already guessed the outcome.

"Now that this place has been destroyed like this, there shouldn't be anything to be found, and it seems that we can only risk going to the map to mark it..."

Before Shen Chen could finish speaking, a landline in the monitoring room rang.

"Jingle Bell ~~Jingle Bell ~~ Jingle Bell ~~!"

A pleasant ringing bell echoed in the small monitoring room, but Shen Chen felt that it was their life-saving bell.

"Fuck!" Shen Chen scolded secretly.

Quickly ran over and picked up the phone,

"Hey! You belong to that unit, and by whose orders did you come to the rescue? ”

Before Shen Chen could speak, an inquiry with a commanding tone came from the other end of the phone.

Hearing the voice on the phone, Shen Chen was not happy, this proved that there were still living people in this research base, and it was possible that the actions of himself and others had already been discovered by them.

This can be proved by Shen Chen's phone ringing as soon as they arrived in the monitoring room.

"Who are you?" Shen Chen asked coldly.

He didn't pay attention to the other party's inquiry, and the person on the other side knew that the institute was full of zombies, and the ringing of the phone would attract the attention of a large number of zombies, so he still chose to call.

This didn't consider Shen Chen's safety at all, which made Shen Chen very uncomfortable.

"Soldiers! Watch your words! There was a reprimand from the other side.

"I'll fuck you! If there is a fart, let it go. I don't have the time to play official with you. Shen Chen could already hear the messy footsteps of zombies outside, so he didn't have the time to waste time with the person opposite.

"Young man, I'm the head of this lab, and the zombies around you are gathering around you fast. You rush first, we're in the high-risk lab now. The phone was replaced by an old man's voice.

"Good!" Shen Chen replied decisively.

"After you get out of the monitoring room, break through to the passage on the right, there are relatively few zombies here." The other side reminded.

"Thanks!"

Shen Chen didn't have time to say anything, because he had already seen the voice of the zombie and threw the phone away.

"Let's go! Rush out and go to the right! ”

Shen Chen shouted at the two of them.

A few people are also not saving ammunition, and the rifle is fired in bursts into kills, and then after killing a few zombies rushing in through the gap.

Shen Chen opened the door of the monitoring room and rushed out first, and there was a series of strafing shots at the oncoming zombies.

"Quick! Intersection on the right! ”

Seeing that the zombies were about to come up, Shen Chen shouted loudly to the two people inside.

Xue Yang heard his words and shouted at Li Bing: "After the break!" ”

Li Bing nodded, holding a rifle to accurately kill the zombies rushing behind.

Xue Yang rushed out of the monitoring room, took a look at the situation outside, picked up his gun and pointed at the intersection on the right, shooting a few zombies that pounced, and quickly ran to the right with the gun.

"Quick! Come out! Shen Chen shouted behind him.

At this time, there were more and more zombies surrounding him, and he was almost unable to resist it.

Hearing this, Li Bing put away his gun, ran out of the monitoring room quickly, and patted Shen Chen on the shoulder when he passed by.

Seeing Li Bing coming out, Shen Chen didn't resist hard, and retreated back without shooting.

In this kind of passage of less than two meters, the zombies crowded together and kept rushing towards Shen Chen and the others, although the power of the rifle was very large, but the relative accuracy dropped a lot.

And the zombies will only lose their ability to move after hitting the head, and the zombies in front will make up for the zombies behind as soon as they fall, which is very unfavorable to Shen Chen and them.

As the person on the phone said, there are not many zombies on the right side of the passage, but they are only relative.

Even if Li Bing and Xue Yang worked together to kill, the speed at which several people advanced was not very fast.

"! There are so many zombies that they're almost blocked. Xue Yang changed the magazine and roared.

As soon as he changed the magazine, the zombie that pounced on him got a little closer.

The situation on their side is like this, not to mention Shen Chen after the break.

Now he can only shoot back while running, and he doesn't dare to stop at all.

As long as he stayed where he was for a few seconds, he would definitely have to be chased by zombies.

In less than a moment, he had already caught up with Xue Yang and the two in front, and he joined the ranks of the two shooting.

"Quick! The zombies behind are about to catch up. ”

With the addition of him, the speed of several people advancing has accelerated a lot, but it is still a lot slower than the zombies chasing behind.

"Fight!"

Shen Chen gritted his teeth, picked up a grenade from his body, pulled out the safety bolt and threw it into the zombie group in front of him.

"Grenade!"

Shen Chen shouted.

"Holy! You're crazy. Xue Yang looked at the grenade that swept over his head, and reflexively crawled to the ground.

On the other side, Li Bing was already lying on the ground, using the corpse of a zombie as a cover.

After Shen Chen threw out the grenade, he directly flew on the ground and lay on the ground.

"Boom!"

At the moment when several people were lying on the ground, there was an explosion in front of them.

Then there was a sound of breaking the air coming from the ears of several people, and Shen Chen threw out a fragmentation grenade.

Hundreds of steel balls scurried around in this small walk, and the zombies near the center of the explosion were blown into a large area, and the other zombies were also knocked out by the explosion in several waves.

Even the zombies that caught up behind them had a few unlucky ones who were hit on the head by the steel balls in the grenades and lay on the ground.

"Bang!"

Xue Yang shot the zombie lying in front of him, and got up from the ground, only to feel his ears buzzing.

I patted my helmet, and it was better.

looked at Shen Chen on the side and scolded: "You kid doesn't want to live, don't pull me and Li Bing!" ”

Shen Chen now also realized how dangerous his actions were just now, just now a steel ball hit the wall in front of him, and the splashed stones directly cut a big hole on the back of his hand, and blood suddenly gushed out, making him break out in a cold sweat on his head.
