"This is a serum extracted from the mutant beast, which can help the guinea pig become stronger, and there is no mutation."

"We named the first generation of body-enhancing serum, and have passed the experiments of white mice, cats, rabbits, and domestic pigs."

After hearing the researcher's words, Xu Yi knew what they wanted to do.

For human experiments, they definitely want to conduct human experiments.

Only after human experiments can we know whether this agent has any effect on humans.

"Have you found similar serums in the body of the supernatural warrior?" Xu Yi stared at the researcher. After all, this kind of thing is related to the future of mankind, and Xu Yi felt that it needed to be cautious.

"There are similar serums, but the quantity is too small, and it is difficult to extract." The researcher seemed to have expected Xu Yi to raise this question, so he took out another serum.

"This serum was extracted from other supernatural warriors. It took more than twenty days to extract such a little bit. And from the third-level mutant beast, 20 milliliters can be extracted in one day."

The researcher showed that it was less than 1 ml.

Xu Yi twitched the corner of his mouth, then glanced at Ling Yue.

He believed that Ling Yue also knew what the researcher meant.

It's really only him and Ling Yue who can decide on this matter.

Others really can't take the blame.

"Let's use severe sentences to prisoners first. If they voluntarily participate in the experiment, they can reduce their sentences. For details, you can discuss them." Xu Yi gave a plan.

Ling Yue also nodded and said, "After the first batch of zero-bed experiments, you can open the project and recruit volunteers. Now, it can only be kept confidential."

If this thing really works, it will probably attract countless people, so Ling Yue thinks it is better to keep it confidential now.

The researcher excitedly beat his palm. As long as he entered the stage of human experiments, he would have the opportunity to successfully inject this serum into every human, helping humans improve their strength.

Everyone wants to give their own strength, and the same goes for these researchers.

When they saw the supernatural warriors struggling to resist the Zerg, they wanted to fight side by side with the warriors.

"Do it well, if you succeed, you will remember all human beings." Xu Yi encouraged a few words, and then visited their laboratory.

Rigorous, very rigorous.

After Xu Yi visited, he gave such an evaluation.

This makes Xu Yi feel even more at ease.

Xu Yi and Ling Yue left the research center, and Xu Yi was about to go to the Orc World.

"Xu Yi, how long will it take for you to come back this time?" Ling Yue hugged Xu Yi's waist and pressed her whole body against him.

Ling Yue is really worried that the Zerg will attack Iron City again, because the strength of Iron City has dropped a lot now, and it may not be possible to defend if it really attacks.

Although the underground fortress is still being built, there may not be enough underground fortresses to be used when the city is siege.

"Don't worry, it's enough in three to five days." Although Xu Yi still did not plan to take lightning to the Orc World this time, he had a flying backpack.

Using a flying backpack can also make you quick journey.

"So fast?" Ling Yue couldn't believe it. After all, Xu Yi had been there for forty or fifty days last time.
