Although dangerous, the effect is still significant.

In the passage ahead, most of the zombies were directly destroyed by the steel balls in the explosion.

As long as a few lucky ones were not shot in the head, but were also seriously injured by the balls, all of them lay on the ground for a short time and refused to form an effective attack.

"Let's go!" Shen Chen got up and shouted.

Rush into the pile of zombies in front of you first, and run directly on the corpses of zombies.

Xue Yang and Li Bing also reacted quickly, and followed behind Shen Chen in a similar way.

Stepping over the corpse of the last zombie, Shen Chen breathed a sigh of relief, there were only a few zombies scattered in front of him, and the exit was in front of him.

After killing a few zombies, Shen Chen quickly ran out of the passage, pointed around with a gun and did not find the zombies.

turned around and began to cover Xue Yang and Li Bing, who were retreating.

At this time, the zombies on the other side of the passage had already chased to the explosion point, and many zombies tripped over the zombie corpses on the ground and fell to the ground.

It is estimated that there will be people who will loudly remind someone that someone has fallen, but these people are zombies and don't care about the life or death of their companions at all.

The zombies that fell to the ground were directly trampled under the feet of the zombies that surged up from behind, and the zombies on the ground were trampled into rotten flesh in a moment's effort.

"Da Da Da!! Da Da!! ”

Shen Chen held a gun and shot at the zombies chasing behind the two.

Xue Yang, who was running, was frightened, and the cold sweat on his head came down, looking at Shen Chen's muzzle in front of him, he felt that being chased by zombies was not so terrible.

I was afraid that Shen Chen's hand would hit him with a trembling bullet.

After he stepped over Shen Chen's side, he actually had a feeling of the rest of his life.

"! Dare to chase me, let you see how good I am. ”

Xue Yang looked at the zombies that were still chasing behind him, a hideous smile appeared on the corner of his mouth, and he directly took out two high-explosive grenades from his body, pulled out the pull ring and threw them in.

"Lie down!"

He let out a loud shout, and a flying pounce knocked Shen Chen, who was still shooting, to the ground.

Li Bing also rolled to the other side of the passage and climbed to the ground.

"Boom!! Rumble!! ”

Two louder explosions rang out than before,

Then a cloud of sparks rushed out of the entrance of the passage, followed by various gravel dust, which also contained some parts from the zombies.

The few people lying on the ground only felt a violent vibration on the ground, which lasted for a few seconds.

"Ahem~~ Phew!"

Shen Chen got up from the ground, and the oncoming dust caused him to cough, and he fanned the dust in his mouth with his hand, which made him feel much better.

"How? Are you all right? Shen Chen asked.

The explosion seemed to have destroyed the power outside, and the surroundings became dim, except for some emergency lights.

"Ahem! It's okay! Phew, choke me. This is Xue Yang's voice.

"It's fine!" This is Li Bai's.

Hearing that the two of them were fine, Shen Chen breathed a sigh of relief.

Turning on the tactical flashlight on the rifle, Shen Chen walked to the entrance of the passage and shone inside.

At this point, the entire passage was covered with dust, and it was impossible to see inside.

"Roar!"

With a roar, there was a roll in the dust, and an inhuman-like zombie pounced towards Shen Chen.

Shen Chen didn't panic either, aiming at his head was a bullet.

The zombie fell to the ground in response, and then Shen Chen waited in place for a long time without finding the zombie.

As the dust slowly cleared, Shen Chen could also see the situation in the distance. The passage has been blown down by two grenades, and the collapsed stones have completely blocked the passage.

"I'll go! Is it so can't help but blow up? Xue Yang saw the situation in front of him and couldn't help but complain.

"Can it not collapse? You're using a high-explosive grenade. Li Bing looked at him and said.

Xue Yang scratched his head and didn't know what to say, so he could only smirk awkwardly in place.

"At least the zombies are blocked, which is a good thing!" Shen Chen said.

"That's right! Right! I guess there were at least a hundred zombies surrounding us. Does this underneath the lab have so many staff? Xue Yang hurriedly diverted the topic.

"I also noticed just now that most of these people are dressed as ordinary people, and only a few of them are dressed like researchers, and it is estimated that most of them are survivors from the small town above." Li Bing said.

"Hmmm! It should be safe in the research institute, and the people below have arranged the survivors above here. Shen Chen nodded.

Shen Chen turned around and glanced around with a flashlight, this seemed to be an archive room, surrounded by many filing cabinets.

"Li Bing! Take out the map and see where we are now. Shen Chen said to Li Bing.

Li Bing nodded, took out the map and found a clean ground to lay on.

Shining a flashlight on it for a long time, he pointed to the side of the map and said, "Look at the situation here, we should be here." ”

Shen Chen squatted down and looked in the direction Li Bing was pointing, and sure enough, the name marked on it showed that this was indeed an archive room.

"By the way, what happened on the phone just now." Xue Yang asked while guarding the surroundings.

"It's the survivors from the institute calling!" Shen Chen replied.

"It's really surviving, that's great, I'm worried about how to get out."

Glancing at Xue Yang, Shen Chen lowered his head and pondered, "I feel that things are not simple, I guess we were noticed by the other party as soon as we entered the research institute, otherwise that call would not have come in so coincidentally." ”

"Hmmm! It should be. Li Bing nodded.

"So what do they have?" Xue Yang asked again.

Shen Chen lowered his head and frowned, "At first, there was a person who spoke in a very angry tone, and I ignored him, but then an old man said let's go to the high-risk experimental area to find them." ”

"That's right with what we estimated earlier, where did the people from this lab retreat?" Li Bing said.

"Look at the map, we are still some distance away from the high-risk laboratory, it is estimated that this road is not easy to walk, and the people who chased us just now were some ordinary zombies, and there was not a single evolutionary zombie, which made us very puzzled." Shen Chen analyzed.

"Could it be that the high-level zombies here have been wiped out by the people in the research institute?" Xue Yang put forward his own ideas.

"Impossible! According to the previous situation in the monitoring room, there is at least one T2-level power-type mutant zombie in this base. Zombies of this level cannot be destroyed unless they use heavy firepower.

And do you think there will be a heavy firepower arrangement in a laboratory of this level? Li Bing stood up and said.

Xue Yang thought about it and shook his head, but he also felt that it was unlikely.

"That's it! I can't say more. Now that I know where the target is, I can only bite the bullet. You didn't find that there was such a big commotion just now, and there wasn't a single zombie appearing. Shen Chen interrupted the two of them thinking.

"It's a little wrong, it stands to reason that such a loud noise has to attract a few zombies to come." Xue Yang's hand holding the gun couldn't help but tighten a little.

As soon as his words fell, there was a sound of heavy footsteps not far away.
