Bai Susu stood in front of the tank, and the pale green liquid inside occasionally bubbled.

"What is this?" She leaned close to the tank, observing its contents, and exclaimed.

Lin Sen walked to an operating table next to him, and there were a lot of materials scattered on the ground.

"A1 test subject, obtained a booster potion, human genetic mutation?" Lin Sen looked at the materials on the ground, which recorded the experimental items.

After looking at it for a while, Lin Sen shook his head, these materials were ordinary records and had no value at all.

He picked up a document and dropped a photograph from it.

The photo is of a girl, smiling brightly, not knowing her ending at all, and on the photo, the girl's name is printed: Yu Ling.

There was a display on the console, he walked to the monitor, observed for a while, pressed the green button on it, the display lit up, and a person appeared on the display.

"Susu, come here." Lin Sen said, and Bai Susu returned to Lin Sen's side.

"Can you see it? I started recording. The man on the display straightened his clothes, pressed a button, and continued.

"I'm a first-level researcher of A1 Doomsday Experiment, Wu Jianguo, and we are now tasked with studying the mutants and humans in the Apocalypse."

"On the 12th, we found traces of mutation from a female survivor named Yu Ling." As he spoke, he took out a document from his side and continued.

"Through anesthesia and dissection, we found that the survivor was not infected, but she had a genetic mutation, which we tentatively call evolution."

"According to our research, the mutations in the survivors' genes have made her exceed the level of normal people in all aspects of her body, including speed, strength, IQ, perception, and healing ability, etc., we have tested them, and the following is a video of our experiment."

The person disappeared, the screen of the display screen switched, and a sixteen or seventeen-year-old girl, who looked like Yu Ling, was lying on a fixed frame with her limbs tied tightly.

The girl looked around in a panic, and she trembled and said, "You, what are you going to do?" I just want a little food, I don't want it, I don't want it. ”

In response to Rei's request, a researcher in a hazmat suit walked up to her, holding a needle in his hand.

"Anesthetic type C2, twelve CC, injection."

With that, the researcher pricked the needle into Yu Ling's arm and injected the anesthetic into her body.

After a while, Yu Ling lay motionless on the operating table, and the researcher brought a flashlight, peeled off her eyelids, and shone a flashlight into her eyes.

"The pupils are not dilated, the breathing is steady, and the heartbeat and pulse are normal."

The researcher spoke, and the AI program in the monitor behind him recorded what he said.

"Start the trauma experiment." A voice came, and the researcher nodded, stepped aside, took out a scalpel, and walked to Yu Ling's side.

He came to Yu Ling and slashed at Yu Ling's thigh with a scalpel, the sharp blade cut the skin, the flesh inside turned out, and the blood flowed out from the huge knife edge, but the next scene shocked Lin Sen and Bai Susu.

I saw that the incision was healing at a speed that was visible to the naked eye, and the muscles were slowly healing, and the original incision immediately scabbed over and fell off.

"What's going on? How did she do it......" Lin Sen looked at the screen with a solemn face, this kind of healing ability is as good as himself, but he is an experimental subject of the super soldier project, but this person named Yu Ling is an ordinary person.

He thought of what the researcher was talking about in human evolution, and whispered, "Maybe it's true." ”

Inside the display, the experiment was still ongoing, and the researcher put down the scalpel and said, "The trauma experiment is normal, the fourth-level evolution has been determined, and the experiment is over." ”

With that, the display switches back to the person at the beginning.

"We have conducted many experiments to determine that human beings have started the third evolution after the end of the world, and we have discussed it in meetings and divided the evolution into seven levels."

"Through our research, the strength of the evolved human is a cut short of the mutation level strength of the devourer, and the evolution of the second-level human can easily kill the first-level devourer."

"But the number of evolutionary humans is very rare, and we need further experiments for more accurate data." With that, the display was turned off.

Bai Susu watched from the sidelines, she now finally knew what was going on in her body, and why the gunshot wound healed so quickly.

"Brother Lin, did you find anything?" Bai Susu said.

Lin Sen thought for a while and said, "According to the experiment, Wei Ya and the others should also be evolved humans, I don't know if it's a good thing or a bad thing." ”

He walked to the tank and looked closely inside the tank, and could vaguely see a figure.

Boom!

There was a sound in the tank, and the green liquid inside began to churn and slowly disappear, and after a while, the green liquid disappeared, and a girl, standing in the center of the tank, with a tube inserted behind her, and an oxygen mask.

"She's Yu Ling?" Lin Sen compared the photos, because he was wearing an oxygen mask, so his facial features were not obvious.

Suddenly, there was a click in his ears, and he hurriedly turned his head to find that the tank was slowly cracking.

"Susu, get out of the way!" Lin Sen picked Bai Susu up, retreated to dodge, and with a click, the entire tank was completely shattered, and a foul smell filled the air.

"Brother Lin, are you okay?" Bai Susu came back to his senses and asked anxiously.

Lin Sen shook his head, he felt his ass punctured by the glass of the tank.

Hiss!

With a sound, the two turned their heads and looked at Yu Ling, the oxygen mask had fallen off, and after so many experiments, her body looked like it was patched together.

The tube behind her also fell off and fell directly to the ground.

Bai Susu wanted to go up and help her up, but was stopped by Lin Sen, who found that he was holding the so-called green liquid, which was all diluted devourer blood, which had been soaked and soaked, and he didn't know if Yu Ling had mutated.

After a while, Yu Ling stood up tremblingly, she stood up, her hands hung down, her head bowed, this person looked like a dead person.

She slowly looked up, looked around, scratched her head awkwardly, and didn't look very intelligent.

She walked step by step, her mouth made a whining sound, this person was green, it looked strange, she slowly walked towards Lin Sen and them, Lin Sen looked at her vigilantly, and at the same time drew the knife.

Yu Ling still moved forward a little, and when she was about to get in front of them, she fell directly to the ground with a straight face.
