Yan siting squatted down in front of the low-level zombie, looked at the wound carefully, and then said, "this zombie was not killed by human beings, but by his own kind."

Listening to these words, the other four people were shocked.

"Professor Yan, do you mean zombies kill each other?"

"If I'm not wrong, zombies can advance by sucking the nuclei of their companions." Yan siting stood up, took the handkerchief from the assistant and wiped his hands.

"In that case, why do they eat people?"

"Cannibalism is their instinct, and they need to continue their race..."

Su Yao, who had been eavesdropping on their conversation, was completely shocked.

How can Professor Yan see that this low-level zombie was not killed by human beings?

And how did he infer that zombies could advance by sucking their companion's nuclei?

Does that mean he has found a way to make zombies human?

Su Yao resisted the desire to rush out and continued to listen.

"Professor Yan, what kind of zombie do you think killed this low-level zombie?"

"I don't know that." Yan siting said, "it could be a middle-level zombie, a high-level zombie, or a low-level zombie."

Listening to the words "high-level zombie", the assistant was already shaking with nervousness.

He looked around and said in a trembling voice, "Professor Yan, we'd better leave here as soon as possible. If a high-level zombie suddenly jumps out, we will all die here today."

Although the other three are all powers, they can't beat a high-level zombie.

If you don't leave soon, you will die here.

"I don't know if there is a high-level zombie, but I know there is a zombie hidden here." Yan siting said as he looked at Su Yao's hiding place, "this zombie is probably the one I just mentioned. If you arrest him, I will take it to do research."

Hearing this, Su Yao was shocked.

How did Professor Yan find him?

He didn't do anything to expose his position, did he?

No matter, it's important to escape. If they catch him, he will be reduced to a mouse for research.

He is not the protagonist with the aura of immortality, and he will surely die on the experimental platform.

However, he was surrounded by the three powers before he could escape.

And don't know what those three powers did, he suddenly couldn't move.

Day! Is it hard for him to fold here today?

"Professor Yan, we've got him."

Yan siting came over. He looked at Su Yao, who couldn't move. His voice said coldly, "it's a low-level zombie."

There is also a bit of disgust.

Su Yao recognized the dislike and immediately exploded.

If it had not been for his inability to speak now, he would have yelled.

What happened to the zombie?

Even if it's a low rank zombie, he's a different low rank zombie.

"Professor Yan, do you want to kill him or take him back?"

"Take it back. It happens that one of my recent experiments lacks an experimental body. Let's start with him first."

"Good."

Su Yao No, don't you ask my opinion?

"But before you take him away, give him an injection of that medicine to save me time..."

As for the following words, Su Yao couldn't hea
