"Then let's go to the monitoring room first, according to the map marked that this place is only one distance from our experimental area." Li Bing said, pointing to the map.

"Not bad! Looking at the surrounding situation, the power system of this underground laboratory can still operate normally, as long as you go to the monitoring room, you can easily find out the situation of the entire underground laboratory, and at the same time, you can quickly confirm whether there is any live mouth inside. Xue Yang agreed.

After listening to the analysis of the two, Shen Chen thought about it and nodded in agreement.

Now that the goal has been set, they are not wasting time either.

After all, the longer they were delayed at the bottom, the more anxious the people above became, and after a few people sorted out their equipment.

Shen Chen took a badge from the corpse on the ground, which showed the position of the director of the research institute, which should be able to open most of the laboratory's access control.

Shen Chen glanced back at Li Bing and Xue Yang, and the two nodded at him.

Place the card on the recognizer and swipe it, and with the "Drop!" The door to the waiting room opened.

As few people expected, the moment the door opened, several zombies pounced in.

Fortunately, they were already prepared, and they didn't want to be caught off guard like before, and after a few short gunshots, the zombies fell to the ground.

Seeing that there were no zombies coming in, Shen Chen gestured a few times at Xue Yang.

The latter nodded knowingly, cautiously praised the few corpses on the ground, stood outside the door and observed for a while, gesturing to Shen Chen to indicate safety.

Now that they don't know anything about this place, it's better to be careful.

When Shen Chen came out of the waiting room, he found that there was a long corridor outside, the original white walls were stained with splattered blood everywhere, and there were still a lot of torn clothes on the ground, and the corpses that had been pitted into white bones.

Stretched out his hand and patted Xue Yang on the back and motioned for him to move forward.

The outside space became larger, and Shen Chen and the others also replaced their pistols with rifles, forming a standard three-person combat team.

Xue Yang is responsible for opening the way, Shen Chen is in the middle of the strategy, and Li Bing is responsible for breaking the rear, which is Shen Chen's lack of combat experience, and arranging him to protect him in the middle relative to the change of direction.

Coming to the corner, Xue Yang held his right hand and waved it back to signal Shen Chen and them to stop, Shen Chen and Li Bing immediately squatted down and held guns on guard.

Xue Yang leaned against the wall and poked his head out to observe for a long time, then lowered his pace and walked back.

"Outside is an office area, there are five zombies in the hallway, and there are also in the office, but I don't know the exact number, if you shoot, it will definitely attract the attention of the zombies inside."

Xue Yang recounted the general situation.

Hearing his words, Shen Chen frowned slightly, now he doesn't know how many zombies there are in the office, in case the shooting attracts the attention of the zombies, in this environment, as long as there are more than two dozen zombies surrounded, they basically have to explain here.

And in order to facilitate their movements, they put all the long weapons of melee warfare on them, and now the only cold weapons that can be used are only a few daggers.

Shen Chen bit it! For my safety, he still chose to use cold weapons.

"We'll make some noise later, attract the five zombies outside into the aisle, and we'll solve it with a dagger." Shen Chen looked at Xue Yang and said.

Hearing his words, Xue Yang nodded without saying anything, turned around and walked to the corner, and gently tapped the ground with the butt of the gun.

The crisp impact sound was particularly clear in the quiet environment, and it was Xue Yang who controlled the force.

After hearing the noise, a few zombies outside slowly walked towards the corner, while the zombies in the office were still walking aimlessly.

"Whew!" Xue Yang breathed a sigh of relief.

"It's done!" Return to the two of them and make a gesture of success.

In order to ensure safety, after several zombies appeared around the corner, Shen Chen and the others deliberately took more than a dozen steps back to prevent the sound of the fight from attracting the attention of other zombies.

A few zombies walked around the corner, heard the movement in front of them, and began to speed up their pace to catch up.

"There are five in total, everyone be careful to come one by one, and keep a distance first." Shen Chen reminded.

"Understood!"

Several men drew daggers and loaded them on their rifles, holding the guns tightly with both hands.

"It's coming!"

The first zombie had already approached everyone, and Xue Yang stepped forward and kicked it on it, kicking it directly to the ground.

Shen Chen seized this opportunity and stepped forward and stabbed the zombie's head.

After solving the first zombie, the next two zombies pounced at the same time.

Shen Chen rolled on the ground to dodge the zombie's claws, and stood up after pulling away the distance.

The zombie on the left has been pierced in the back of the head by Xue Yang, and the one that pounced on Li Bing, I don't know if it is because the zombie lacks experience in melee combat, Li Bing's shot is only pierced in the shoulder of the zombie.

Seeing the zombie's big mouth gnawing towards his neck, Shen Chen let out a low shout: "Be careful! ”

At the same time, he kicked on the zombie, although he did not kick the zombie away, but it also made the zombie lose its balance, and the big mouth that bit Li Bing closed together in space, making a crisp sound of teeth bumping.

Although Li Bing is a sniper, his fighting skills are not bad, but this is the first time he has engaged in a white-knuckle battle with zombies, and it is inevitable that there will be some mistakes, but he quickly adjusted.

With Shen Chen's support, he pulled out the bayonet stabbed on the zombie's shoulder, flipped the gun and smashed the butt on the zombie's head, and directly lay the zombie's head to the ground.

"Thanks!"

"Yes, watch out for the other two!" Shen Chen reminded.

Three of the five zombies were removed, and the remaining two naturally posed no threat to Shen Chen and them.

With the tacit cooperation of the three of them, the two zombies quickly fell in front of them.

"I said Li Bing, you are too embarrassed, and I want Shen Chen to save you. When you go back, you have to strengthen your hand-to-hand combat training. Xue Yang came over and joked with Li Bing.

Li Bing glanced at him coldly, and said lightly: "Okay! How about you come and be my sparring partner? ”

Xue Yang's smile immediately froze.

"What the hell! Let's hurry! ”

found an excuse and Xue Yang slipped away.

Coming to the corner again, several people walked out with their waists bent, avoiding the glass in the office area so as not to be seen by all the zombies who had regained their sight.

Passing through the office area, several people came to the experimental area separated from the monitoring room, where there was obviously a fierce fight, and various test tubes and documents were scattered everywhere on the ground.

There was still dried blood on the ground, but the more a zombie didn't see it, which made Shen Chen and the others feel a little surprised.

But they didn't pay much attention to it, and the absence of zombies was a good thing for them.

But if the people in the laboratory see this scene, they will not hesitate to pick up the gas mask on the side and put it on, and will quickly exit the laboratory.

Because a visible crack had appeared in a box marked with a virus storage cabinet on the floor, and the test tubes inside were empty.
