"I, I'm a member of the army."

Seeing that Wang Yi's face was gloomy and uncertain, Professor Cheng was afraid that Wang Yi would be unhappy and killed him directly.

"I don't doubt your words." Wang Yi glanced at him and asked casually.

"What kind of research bureau are you alone?"

"And... And, just a few of them died just after the Apocalypse broke out, and a few, just..."

Professor Cheng's face flashed a look of fear. Just now, the two soldiers suddenly went crazy, but they lost a lot of scientific research personnel.

"In that case, you should be just a branch and the headquarters should be in the capital. How do you contact the capital?" Wang Yi continued to ask.

"Yes, there is a military radio station, but now it has been taken away by Li Hengtai." Professor Cheng said truthfully.

"Well, Professor Cheng, do you want to continue to develop the extract of zombie blood?"

Wang Yi asked. It seems that Professor Cheng is a geek of science, and he can also develop the refined liquid under the condition of blocking information. Although it is not a finished product, it is also enough to prove the personal value of Professor Cheng. Wang Yi will not let it go.

"I, can I still study it?" Sure enough, on hearing Wang Yi's words, Professor Cheng even put green light in his eyes.

"Brother Yi, for what reason has this old thing killed so many people and turned two soldiers into monsters with no human body and no corpse? What's the use of keeping him?"

Li Hu couldn't help saying that although he knew he shouldn't have questioned Wang Yi's words, he couldn't help it.

"Zhang Fei also used the extract, and now he is very powerful." Wang Yi said lightly.

Zhang Fei is only a three-level evolutionist now, but his speed and strength are far more than those of other three-level evolutionists in the gathering place, and he is almost catching up with the four level evolutionists before Wang Yi.

Zhang Fei doesn't have any powers. It's all the effects of the extract, including Han Wan'er.

A little girl, when Wang Yi saved her at the beginning, she was even a second-class evolutionist, but she could kill the same level of power powers with her bare hands, which was very powerful.

What Wang Yi needs now is this kind of powerful staff. Even if it's just an opportunity and there is no result, Wang Yi will firmly grasp it. What's more, the refined liquid is feasible. Professor Zhang has developed it, but at that time, Wang Yi only brought back one and it has been used by Zhang Fei.

"Zhang Fei? Who is Zhang Fei? He's missing the extract! "

Professor Cheng's eyes were wide open and his face was unbelievable. The main reason was that he heard an unusual meaning from Wang Yi's words.

That Zhang Fei, it seems, has not become the so-called human corpse species.

"I am Zhang Fei." Zhang Fei walks up to Professor Cheng and looks down at him.

Zhang Fei is tall and tall, while Professor Cheng is a thin old man. He just feels a huge pressure on his face. Professor Cheng takes two steps back and almost sits on the ground.

"You, have you ever used extract?" Professor Cheng stammered.

"Why, can't you?"

Zhang Fei glanced at him and didn't like Professor Cheng very much.

"Zhang Fei used it twice. The first extract should be a semi-finished product, which almost made Zhang Fei a zombie. What really improved his physique was another extract." Wang Yi said.

"Where, do you have any more?" Professor Cheng is also not afraid, and quickly asked.

"No, there's only one left, but it was developed by a professor surnamed Zhang." Wang Yi said.

"Zhang?" Cheng Jiao hesitated a little and blurted out“ Zhang Jiancheng

"Do you know him?" Wang Yi asked subconsciously.

"He's one of us, too. Now... He should be in Jinling." Professor Cheng hesitated a little.

It seems that Professor Cheng and Professor Zhang are from the March 27 Research Bureau.

Wang Yi nodded to himself. In this way, he could explain why they could all come up with something like refined liquid.

But what makes Wang Yi more concerned is that Han Wan'er's extract was provided by a secret organization, and this secret organization is also in the capital. Could they be the people of the March 27 Research Bureau?

"Well, can you give me some blood?"

At this time, Professor Cheng hesitated to come to Zhang Fei.

"Go away." Zhang Fei only gave him one word.

Professor Cheng looked at Wang Yi in embarrassment.

"What do you want his blood for?" Wang Yi asked.

"He has been modified by refined liquid, and his constitution is totally different from that of the evolutor who uses basic meat. I think if he can be my research object, it should help me extract the refined liquid from the zombie blood more quickly."

Professor Cheng said with a full face.

It's not who he's cheating, but with Zhang Fei's blood, he can reverse research and complete the extraction in this way.
