Nothing is achieved overnight, and the success you see is the result of the efforts of others in countless days and nights, and the accumulation of others for several years or even more than ten years.

After the failure of the first transformation of the progenitor virus, in the next few days, except for eating and necessary rest, Chu Hai hardly left the laboratory.

Virus modification is not an easy task, and even comes with great dangers, it can fail, but there must be no surprises.

This requires him to concentrate on the process of conducting the experiment, and the person can do one thing for several hours, but for several days and nights, the mental damage will be very great.

"Senior?" Xiaoxiao saw him rubbing his temples with a painful expression, and she couldn't help but feel a little worried.

"It's okay, I'll hold on a little longer, and I'll be almost fine." He waved his hand to tell her not to worry, but the pain on his face did not diminish in the slightest.

This is the thirteenth time he has undergone virus modification, and before that, the injected mice have either become furious or dying, but they also have something in common, that is, their bodies have been strengthened to varying degrees in a certain aspect.

The only flaw is that the mice cannot express their bodily feelings, and all observations are superficial. Chu Hai didn't dare to dissect their corpses, the risk was too great, even he didn't know what kind of weird compound substance the virus had turned into in their bodies after being modified by him, and he could only dispose of these corpses by special means.

As an assistant, Bai Xiaoxiao, the only thing she can help him in the past few days is to deal with some small and tedious things, her knowledge, and her cognitive ability of microorganisms, compared to it, there is too much difference, and joining in by herself will only slow down the progress.

What she has to do is to collect data and collect information, maybe Chu Hai can get some inspiration from it. Pain is to watch the person you like suffer and you can't do anything about it.

Two hours later, Chu Hai looked at the bright red liquid in the needle, stroked his forehead with one hand, propped his elbows on the table, and let out a helpless sigh.

He tried almost everything, and every time he failed, he would consider all possibilities to avoid the same mistake in the next experiment.

If he fails again this time, he can only rest for a while and wait for him to figure it out.

"Ancestral Virus Modification Program, the fourteenth experiment, fourth-level researcher Chu He, assistant Bai Xiaoxiao, test subject, guinea pig." Chu Hai took his glasses, took the needle in his hand, and walked to the experimental table, Xiaoxiao had already fixed the isolation box.

The injection process was smooth, and he didn't have any negative emotions because of the long-term failure.

After the injection is completed, the needle is withdrawn from the body and the isolation box is closed.

After a minute, the mouse's upper jaw and nose twitched, the lower canines gradually became larger, and rarely, its black eyes remained clear.

Chu Hai didn't show much excitement, and since the eighth experiment, almost all the white rats have been able to survive this stage.

It gradually became uneasy, running to the corner on four small short legs, its front teeth and claws constantly scratching the isolation box, making a sharp and piercing sound, and the changes in its body seemed to make it extremely uncomfortable.

The rat's body has basically stabilized after doubling in size, and the reason why the body expands is probably to better withstand the pressure of mutation.

Saliva dripped down its teeth to the ground, and the rat crawled, lowering its center of gravity, and the edges of its eyes began to redden, and its body was constantly shaking, indicating that it was trying its best to dominate itself, but it was on the verge of losing control.

Bang! Bang! It moves towards the same point, constantly striking with its skull. Seems to want to break out of the cage.

After a short while, the rat gradually calmed down, the frequency of impact became less and less, and the bloodshot on the edge of the eyeball began to slowly subside.

It began to run around in the isolation box, looking at the world around it with curious eyes, Chu Hai had an illusion that the intelligence of this white rat seemed to have improved significantly, at least the behavior of touching the isolation box and retreating back with extreme speed should never appear on it.

"Senior, you succeeded."

"No, we succeeded." Chu Hai chuckled and turned around and hugged her into his arms, both of them were wearing chemical protective suits, and they couldn't feel anything at all except each other's heavy clothes.

Bai Xiaoxiao was frightened by his sudden move, for so many years, this was the only time the two of them had been so intimate, and when he reacted, when he wanted to hug him, he had already withdrawn and left.

"Senior, aren't you happy?" Both of them understood what the success of this potion represented, and from now on, the human world could be changed by it, and they would have the strength of a beast, the sight of a frog, and the sense of smell of a mouse......

The evolutionary ability of living beings has infinite possibilities, and even the brain domains that humans have not been able to involve have opened a gap for them. But from his body, Xiaoxiao actually felt worried.

"Actually, we're only halfway there." He looked at the strangely behaved white rat in the quarantine box, and his eyes flashed with a complicated light.

The value of the existence of mice lies in the applicability of the drug, but it does not mean that the mice are harmless, and the drug will not produce adverse or excessive reactions when used in people.

She also became sad all of a sudden, they seemed to have succeeded, but this kind of drug, after all, is to be used on the human body, an unknown, may not be completely perfected experimental drug, who will accept the injection? Even they don't have any certainty, and they can't predict what will happen after the human injection, who would be so stupid?

"Isn't it okay to use prisoners?" Aren't there so many troublemakers in the Vault? Wouldn't it be enough to catch a person who is constantly doing evil?

"People are sanctimonious creatures, if I really make this request, they will not only refuse, but they will definitely think that I am engaged in some kind of human experiment, forget it, don't think about it, let's go out first! I'm tired these days. "When he proposed to Shi Changkong at the meeting to study the human body enhancer, he set the rules of the game, if he could not ensure the safety of the medicine, he would never use it.

Xiaoxiao followed behind him, looked back at the red potion lying on the table, and secretly moved her mind in her heart. All drug experiments are done in duplicate, and if the first time fails, they are destroyed directly, and if they are successful, in order to avoid chance, another mouse is injected a second time, so as to avoid chance.
