National Doomsday: I am the master of viruses, I evolve by eating poison

Su Yunfei recalled the scene when Karen disappeared just now.

He found that he seemed to have used a skill like teleportation, so he disappeared instantly.

This guy can also burrow into the ground.

He is really good at escaping.

Xiaolang looked around the biochemical factory and roughly figured out the basic layout.

But he still couldn't find Karen.

In this case, Su Yunfei had to go out in person.

Seeing that there was nothing for him to do, Xiaolang turned into a black shadow, covered the materials left by Karen, and devoured them happily.

Su Yunfei walked into the entrance of the factory.

With such a super god skill as forced extraction, he didn't worry about any tricks from the other side.

Tian Mengxue was stunned for a moment.

Then, she chose to follow him and enter as well.

Su Yunfei looked back at her, didn't say anything, and acquiesced.

The two of them, one in front and one behind, can also take care of each other.

Tian Mengxue vigilantly observed the back to guard against possible crises.

Although Karen disappeared, his breath was left in the place where he appeared before.

Su Yunfei took out the tracking powder.

This was obtained during the beast tide. As long as there is the smell of the target, it can be tracked.

Soon, a faint red mist appeared in the air, and Karen's breath was marked.

It would be much easier to follow the map.

Not long after, Su Yunfei and Tian Mengxue found Karen in another laboratory.

Karen, who was wearing a clown makeup, smiled like a clown when he saw them, and laughed a series of devilish laughter.

Then he flashed again and disappeared again.

Su Yunfei caught his afterimage and was about to launch a mental attack, but his head hurt a little, so he stayed put.

"Keep looking!"

Su Yunfei called the little wolf to surround this guy together.

He didn't believe that Karen could release the teleportation skill infinitely.

Tian Mengxue followed behind, frowned slightly, and observed the surrounding environment.

The inside of this biochemical factory is like a maze, and many places look the same.

Tian Mengxue frowned secretly, thinking of a better way.

Suddenly, a protective door at the end of the corridor closed quickly!

Followed by the sound of locking.

This protective door has nine layers in total and is very complicated.

And at the other end of the corridor is a dead end.

Outside, Karen's laughter rang out again.

He said in his own language:

"Su Yunfei, your winning streak will be ended by me! Hahahaha! I’m the King!"

Su Yunfei remained calm and unmoved.

In the long corridor, doors extended from the wall and fell down.

The space where Tian Mengxue and Su Yunfei were located was separated layer by layer, getting smaller and smaller, and finally there was only more than three meters of distance left.

In silence.

Tian Mengxue asked: "What should we do now?"

Su Yunfei said: "Break it and get out."

So Tian Mengxue tried it, raised her hand, and shot out a huge ice crystal arrow.

It hit the wall with a deafening sound, and the ice crystals shattered all over the ground.

However.

The wall was only slightly dented, and was not penetrated.

Tian Mengxue collected the ice crystals again and looked at Su Yunfei silently.

Su Yunfei stared and thought.

The impact force of the arrow just now must have exceeded a hundred tons.

The material of this wall is really good.

If it is difficult to crack it by force, it is faster to extract it by force.

Su Yunfei was about to use this skill silently.

But there was a sharp pain in his head.

It was as if a sharp knife stabbed into it!

"Hiss!"

Su Yunfei hissed in pain.

This was the first time he was injured.

And it was mental damage!
