Chapter 1211 (2/2)

Mutant mice have good jumping ability. They are already the size of a wolf dog. Jumping on the vent is no problem at all.

Just as the first mutant mouse was about to jump up, a strong bomb rolled out of the vent and fell directly into the rat group.

”Boom!” With a loud noise, the strong bomb exploded in the room, bursting out extremely dazzling fire and surging air waves.

The powerful air wave and explosive force directly destroyed the whole room, and the mutant rats in the house were also fried into meat mud, without a lifetime

The vent is large. Although the entrance is only enough for one person to walk together, when you get to the main road, you can accommodate people to walk upright. This ventilation system connects the whole huge laboratory. Through this ventilation system, you can go almost anywhere.

”Are you familiar here?” Shen Feng asked them.

The two shook their heads at the same time, and duraf said, ”predecessors have come to cherno city before, but they are not as deep as us. I think we have made history.”

”And I have a map of the laboratory and no drawings of the ventilation system.” Kasha should also answer.

”Let's go. Let's go ahead first.” Shen Feng was helpless.

The ventilation system was like a maze. Duraf looked around and said, ”I really can't find anything here. I'd better go out first.”

”Good.” Several people just want to find a place to walk out of the ventilation duct, ”Dong!” With a loud noise, the ventilation duct seems to be damaged by something

I saw a big hole in the pipe 20 or 30 meters away from several people, and several large mutant rats rushed in.

It turned out that they had never given up chasing a few people and came here in hot pursuit from other places.

”They found us.” Duraf looked at the mutant mouse rushing into the ventilation duct with a startled look on his face.

With that, kasha picked up the pistol and pulled the trigger directly.

”Bang.” A mutant mouse was shot in the head and fell directly into a pool of blood. A mutant mouse fell down and more mutant mice rushed up.

”Withdraw!”

Shen Feng watched the mutant rats swarming up, turned his head and rushed to the nearest exit.

When he came to the exit, he looked down. There were all gray and black shadows below. Their feet were basically occupied by mutant mice and could not go down at all.

”Not here. Find another place!” Shen Feng continued to run forward.

Mutant mice were fast, even faster than those wolfdogs, and they rushed from all directions of the pipe and soon surrounded the people.

”There's a road over there!” Shen Feng ran in the direction of the only pipe without mutant mice.

Before rushing over, Shen Feng's heavenly demon ring flashed, and two high explosive grenades appeared in his hand.

”Boom! Boom! ” With two deafening noises, two high explosive grenades exploded among the rats. The high explosive grenades were very powerful. They killed the mutant rats and broke their ventilation pipes at the same time.

And breaking the ventilation pipe is his ultimate goal!

As the ventilation duct was blown off, the mutant rats on both sides were immediately isolated in the distance.

”Blow up the behind you!” Kasha said to Shen Feng.

”No, I just blew up the branch pipe, and our main pipe collapsed after the explosion.” Shen Feng said in a deep voice.

If it collapses here, there are rats below, which is equivalent to falling into the rats
