During the period of the "Lightspeed Incident", Xu Shan soaked in the laboratory every day, conducting simulation experiments for the "Volunteer Experiment" again and again.

Since he was promoted to professor, his whole person has taken on a new look, and almost everyone in the biology school has treated him with respect, even the vice dean has gotten closer to him.

The most important thing is that he has just solved the problem of "biological regurgitation" and is preparing to report to Zhang Tianlin.

"Xu Shan, didn't you leave yesterday?"

A sentence broke the silence of the laboratory.

"Mentor, you're here, and I'm about to report good news to you!" Xu Shan said happily.

"Is it about 'volunteer experiments'?" Zhang Tianlin said with a smile.

"No," Xu Shan said, "it's the problem of 'gene regurgitation' solved!" ”

Zhang Tianlin was very happy to hear this, and hurriedly asked what was going on. Xu Shan rubbed his eyes, printed out the information he had organized, and respectfully handed it to Zhang Tianlin.

"That's great!" After reading the information, Zhang Tianlin couldn't help but praise, "Xu Shan, I'm really proud of you, you have overcome such problems, and your achievements will definitely surpass me in the future!" ”

Xu Shan was excited, naturally he didn't dare to forget the teacher's teaching, and hurriedly said humbly: "Mentor, you are too modest, there is still a big gap between me and you." Besides, the reason why I am where I am today is because of your teaching! ”

"You've worked hard these days, you haven't been home for a few days, have you?" Zhang Tianlin said with concern.

Xu Shan nodded.

"You go home and rest for two days, and then we're going to talk about the final plan for the 'volunteer experiment'. The tough battle is about to start......"

Although Xu Shan was exhausted, he left the biological institute excitedly.

Zhang Tianlin locked himself in the laboratory and began to test the solution of "gene regurgitation". He did several sets of experiments, and through several hours of observation, there were no problems with the experimental mice, and the experimental data were normal.

"It seems that this problem is solved." Zhang Tianlin was secretly happy, but when he thought that he was the real experimenter, he couldn't help but feel a little pessimistic.

However, in order to treat his eye disease, he had to take a risk.

Three hours passed, and with the sound of the cryogenic equipment slowly turning on, three biologics appeared in front of him. He named it Biologics B and waited for the next time Biologics A failed.

……

A week later, the "Volunteer Experiment" officially began.

Zhang Tianlin, Xu Shan and other personnel involved in the experiment made preparations early on, carried out the final inspection and debugging of the experimental equipment, and only waited for the arrival of volunteers.

Of course, for such an important matter, Lin Shengwei, president of the Institute of Biology, also attended, he sat on the left of Zhang Tianlin, and on the right sat Li Qingyi, vice president.

Lin Shengwei looked at his watch, at a quarter past ten, the car to pick up Ye Dongming set off at seven o'clock, and it had been more than three hours.

So, he asked Zhang Tianlin in a low voice: "Lao Zhang, is it time to arrive?" ”

Zhang Tianlin said in a low voice: "It's hard to say, Zhang Mei didn't agree at first, for fear that she would change her mind temporarily." ”

"Didn't Ye Dongming agree?" Lin Shengwei said.

"Well, Ye Dongming is determined, let's wait patiently."

As soon as the words fell, a business reception car slowly appeared, it was the car that picked up Ye Dongming, and everyone got up one after another when they saw this.

Zhang Tianlin and Lin Shengwei walked quickly to the car, and when the car door slowly opened, they saw Ye Dongming's face. He was the only one in the car, and Zhang Mei was not seen. Then, the medical staff helped Ye Dongming into a wheelchair.

Lin Shengwei hurriedly stepped forward, held his hand, and said gently, "Dongming, hello." I'm Lin Shengwei from the Institute of Biology, don't be nervous, I believe we can do it. ”

Ye Dongming knew that no matter how indifferent he was at home, he had to change it on this occasion. So he said lightly: "Dean Lin, thank you." ”

"You know me?" Lin Shengwei said with some surprise.

"Hehe, I've seen it on TV."

"Why didn't your mother come along?" Lin Shengwei thought about it for a while, but still asked this question.

At the mention of Zhang Mei, the expression on Ye Dongming's face became a little complicated.

He knew that the reason why she didn't come was because she was afraid of losing her son completely. But if you do this for the rest of your life, isn't it a loss?

"Maybe I can't bear it." Ye Dongming said lightly.

At this time, Zhang Tianlin said with a slight smile: "We can understand the feelings of being parents, but don't worry, we will definitely hand over a reborn you to your mother." Dongming, do you believe it? ”

Ye Dongming raised his head slowly, a glimmer of light flashed in his eyes, this light should be the hope of rebirth.

He nodded emphatically and said in a deep voice, "Then it's hard for everyone!" ”

As he spoke, Ye Dongming took out an envelope from his jacket pocket and handed it to Zhang Tianlin, which was the "volunteer experiment" to sign the agreement.

"My mother and I have already signed," Ye Dongming relaxed a little, "When will we start?" ”

Zhang Tianlin looked at Zhang Mei's signature, two simple words, but she wrote in different thicknesses, horizontally and vertically, and there was a little watermark in the middle of the envelope, which was clearly a teardrop.

He could imagine how much pressure Zhang Mei was under when she signed, and he could also understand her heavy mood at that time.

"Let's go to the lab first, and we'll explain the main points of the experiment to you one by one."

In the laboratory, only Zhang Tianlin, Lin Shengwei, Xu Shan, and a few assistants and medical staff were not allowed to enter.

Zhang Tianlin introduced Ye Dongming: "This is Professor Xu Shan, who is the person in charge of this experiment. ”

"Hello Professor Xu, I have worked hard, and the rest of my life will be in your hands." Ye Dongming jokingly said that he seemed to be surprised to be able to say such a thing.

Perhaps it is the indifference to life and death that can give birth to such a state of mind at this moment.

Xu Shan was stunned for a moment, but he was also surprised, so he smiled politely. Then, he said solemnly: "Don't worry, we will do our best!" ”

After getting Zhang Tianlin's signal, he continued: "What I want to say next is very important, I will try to be as popular as possible, if you don't understand, you can ask in time, and I will answer patiently." ”

……

The experiment was conducted in two phases, but was done in one go.

In the first stage, Ye Dongming's genes were "gene fused" with the genes of the experimental mice through comparison, and then the fused gene strand was reintegrated. In the process of integration, the gene strand that is not beneficial to humans is eliminated to avoid the phenomenon of "gene rejection".

This process takes about four hours.

If the first phase is successfully completed, the second phase can be carried out.

The purpose of the experiment is to regenerate Ye Dongming's legs, and the salamander gene with strong regenerative ability will be used. The regenerated cells in the salamander's body have a memory function and can regenerate new bones, muscles, and nerve tissues, which are the best tools for human amputation and regeneration.

Xu Shan will fuse the extracted salamander regeneration gene with Ye Dongming's gene again. Of course, "gene fusion" is only the first step, because the successful fusion alone is not enough to make him give birth to legs, but also to let the regenerative genes complete the "phagocytosis" process, and continue to achieve regeneration through "regurgitation".

This stage takes about six hours......
