"How is the situation, do we have to stand a little further away? I don't want to be cannon fodder."

Xiao Yun saw the red light in those tunnels, and felt that Liu Feng was about to detonate the bomb again. He was already scarred, and he couldn't help but squeeze his body into the corner of the ventilation duct, wishing to climb back to the original place.

"Do you think I only have that trick? Come down, it's okay."

The three armor-piercing beasts were quickly under the control of the parasites. They emerged from the tunnel and lay neatly in front of Liu Feng, letting him assign them.

"You punch a hole in the wall in front of you and let the two of us pass."

Liu Feng issued an order, and the three armor-piercing beasts acted immediately. The wall of this warehouse was soft soil for these armor-piercing beasts.

After a while, the smell of the warehouse opposite came over. It was the smell of formalin that Liu Feng had smelled before.

"This is too unpleasant."

Xiao Yun covered his nose and Liu Feng walked in. The strong smell inside made them cough violently.

Liu Feng had to make the armor-piercing beast dig a hole in the outer wall, trying to let the outside air flow in.

The armor-piercing beasts acted immediately, but there was actually a fence outside this outer wall. Although there was wind that could penetrate in, there was no way for them to get out from here, and even the armor-piercing beasts were helpless.

"The structure here seems to have changed. It's not like warehouses arranged side by side as we imagined."

Liu Feng quickly discovered the problem. They strayed into the center of these warehouses, farther and farther from the entrance.

This time the self-explosive insects took a clear picture of the surrounding environment. There was a five-meter-wide and ten-meter-long pond in this warehouse, and the smell of formalin rushed to the heads of Liu Feng and Xiao Yun.

But those armor-piercing beasts are very familiar with this place, they actually crawled into the pool and took a leisurely bath in it.

"This genetic modification is really good. It's hard to say that all the formalin solution has turned into nutritional milk powder, which actually raises these armor-piercing animals to be fat and big."

Liu Feng leaned over to see if there were any other creatures in the pool. When he was holding his nose and approaching the pool, a zombie's hand suddenly climbed up the pool wall. He suddenly jumped up and said The stench all sprayed on Liu Feng's body.

"Uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu!" The zombie seemed to be a poisonous gas jet, causing Liu Feng to take a step back suddenly.

He released the moth all the time, letting it flap its wings desperately, trying to disperse the smell, but unfortunately the harvest was minimal. The ventilation system here is very strange and it is not regular.

"There are still zombies here! Is it the experimental product of the previous experiment!"

Xiao Yun glanced at the wound on his body, immediately gave up the close attack, and directly took the gun and shot the zombie's eyebrow.

The body of the zombie fell backwards and fell directly into the pool. Liu Feng immediately controlled the armor-piercing beasts and bit the zombie's neck.

"Woohoo!"

This battle has just begun. More and more hands are climbing up from the pool. Their fingers and skin have been soaked into dark gray. The rotten flesh looks more terrifying, and it is these that make people even more unbearable. Bad breath of zombies.

They had been soaking in the pool for too long, and the smell in their mouth was enough to kill a person, causing Liu Feng and the others to cough.

"How much is hidden in this pool, I can't finish it anyway."

Xiao Yun kept firing, but more and more zombies crawled out.

Liu Feng discovered that these people were wearing clothes from this military base. They should have been staff members here before, and they died very strangely.

The clothes on their bodies are so neat, as if they didn't panic before they died.

These zombies have no sense of direction. All the zombies will only move forward no matter where they come out. They will not start to fumble along the wall until they hit the wall and continue to find a way out.

These zombies turned the whole room into a formalin steamer, no matter where Xiao Yun and Liu Feng were standing, they could smell a lot of chemicals.

"These zombies seem to have been programmed by someone, and the way they walk is too rigid."

Xiao Yun felt that the way they walk was too regular. Even if they shot them, these people would get up and return to their original positions to continue walking.

He couldn't help but glanced at whether there were cameras around him, to see where the people behind them were.

"I can't manage that much. If you ruin this place, you can naturally go out!"

Liu Feng summoned the iron tooth insects, and kept biting at these zombies, but the formalin solution also had an effect on the iron tooth insects, greatly reducing their speed.

The corpses on the ground were always unclean and lined up in front of Liu Feng, even if they wanted to move a step, it was not easy.

And the reaction in the system was also very strange. This time it was not directly given experience, but a few percent.

【Ding! Congratulations on successfully killing a compound zombie and gaining (205000) experience points! 】

What does this mean, it's hard to kill all these zombies to get the final 5000 experience points.

Liu Feng remembered the zombies of the military commander who had been dead for hundreds of years. The overall capabilities of these zombies were comparable to him, which was not easy to deal with.

"I think there is a problem here. These zombies are definitely not that simple."

Liu Feng saw that there were some other creatures swimming in the pool, but the pool was very deep and could not see the situation below temporarily, but he was certain that they were not ordinary zombies.

"Let's go hurry up, if the two of us soak in it will definitely become specimens."

Xiao Yun found the door of this warehouse, and according to the serial number, after exiting from here, it was the C5 warehouse they were thinking of. As long as they took a look at the situation inside, they could go back with their weapons.

This door appeared too conspicuously, making Liu Feng feel that it must be a trap.

"Don't touch it!" Liu Feng yelled, but it was a little late. Xiao Yun's hand was burned by the formalin on the doorknob, and the bones inside were vaguely exposed.

Formalin liquid is not corrosive, but this solution seems to be a mixed solution in this place, specifically eroding human skin.

"Fucked, it turns out they meant this."

Xiao Yun looked at his hand and then looked at the surrounding space, only to find that the major event was not good. The zombies just crawled around and had already smeared the surrounding walls and floors with this corrosive solution. And it is specially used to fight against living people.

No matter where they touched, they had to burn their flesh before they could get out, but if so, they wouldn't be alive.
