Zhang Leyang decisively agreed to accept the trial, and after he agreed, Huang Jingyao also began to discuss other matters, such as the cost of the test he was going to write on the contract, which was 100,000 yuan as a base, and if the test was successful and Zhang Leyang grew a new thumb intact and smoothly, Huang Jingyao would pay him 100,000 yuan.

If he grows a deformed thumb for the first time, he will have to be surgically removed and recuperate, and Huang Jingyao will pay him 500,000 yuan as remuneration, and other expenses incurred in surgery and recuperation will also be borne by Huang Jingyao.

After saying such conditions, Zhang Leyang was stunned again, even if Huang Jingyao had said before that he would not let him test the drug in vain and do this test in vain, but the salary of hundreds of thousands of dollars at a time still scared him.

"Don't think it's a lot, it's just an experiment, there is a lot of risk, I'm only fifty percent sure that it will succeed, so it's right to give you a reasonable remuneration, if this is a mature product after testing, then I'll charge you." Seeing the other party's stunned appearance, Huang Jingyao explained with a smile.

"Uncle Yao, you really don't need so much, even if this is an experiment, you give too much, if you can succeed at one time, I will take advantage of the sky, you must not ask you for money, if you fail to grow a deformed thumb, then even if the process will suffer, give me one or two hundred thousand is enough, how can I use as much as five hundred thousand, this is too scary." Zhang Leyang waved his hand again and again, he felt that if he could have such a terrible reward for every test, he would simply go to be tested by others full-time in the future. Of course, this is just a very absurd idea, and I know that it is impossible to get such a high price for ordinary experiments.

Otherwise, there are still so many people in the world who are running around on the poverty line and have such wealth to attract. You're just getting a healthy person to voluntarily cut off a finger to be your experiment. There are a lot of people who have come to apply.

Huang Jingyao was also a little crying and laughing. He didn't expect that the other party would be too much, well, he also knew that the price was a bit high, but after all, this was his nephew's good buddy, and the experiment also needed to endure a lot of pain, so it was appropriate to give more, but Zhang Leyang didn't accept it.

After a long stalemate, Huang Jingyao reluctantly re-set the price. That is, if the experiment is successful, he will pay the other party 50,000 yuan, and if it fails, he will pay 300,000 yuan to him.

After this contract is completed, the rest is much easier, and even this contract is very simple, there are not so many rules and regulations, Huang Jingyao drafted it himself.

After the official signing of the contract, Huang Jingyao started to act, but this action was not to directly operate on Zhang Leyang, but to take various tissue cells and other tests in the other party's body. I also did a lot of surgical tests, and I was busy until the next morning.

After getting the results of various laboratory tests. Huang Jingyao still has to remix the prescription.

After all, no matter how similar the genetic sequence of a mouse is to a human, it is just a guinea pig, not a real person, so the addition or subtraction of the dose of some medicinal materials is necessary.

The next night, in the dead of night, Huang Jingyao comforted Zhang Leyang again before starting to anesthetize him.

The severed finger of his right hand was a few years ago, and the broken flesh and bone there had already healed again, and if he wanted to rely on drugs to induce limb regeneration, he had to re-cut the intact flesh and blood there, which was not a small pain, anesthesia was a must, and it was also one of the biggest reasons why Huang Jingyao said that even if the experiment was successful, he would have to pay his salary one of the biggest reasons.

Surgery is not a trivial matter, anesthesia, postoperative recuperation, can not be solved in a day or two, and an operation is definitely more serious than a disease.

Huang Jingyao had never operated on the human body before, but his anesthesia and excision surgery ability had been honed a lot on nearly 100 mice, coupled with the influence of ultra-extreme talent, cutting the healing part of the thumb fracture was only a minor operation, and he only needed to remove a few millimeters of complete flesh and blood there, so he dared to do it himself.

However, looking at Zhang Leyang who had fallen asleep, Huang Jingyao couldn't help wiping a cold sweat before he quickly moved his hand in front of the operating table.

After more than ten minutes, a new incision had appeared on Zhang Leyang's right finger, and the flesh and blood were blurred, so Huang Jingyao hurriedly took out the potion that had been prepared in advance and let his right hand dip into it to absorb it.

The absorption process is also much slower than that of the mouse absorbing the drug, and after another half hour, when Zhang Leyang completely absorbs the regenerative induction drug, his incision also returns to peace, although it still looks a little amazing, and it is no longer oozing blood.

Huang Jingyao didn't say that it was okay at this time, but started to prepare other needs, and when Zhang Leyang woke up, he would also help him with infusions, blood transfusions, and even medical analgesic pumps to help him postoperatively analgesia.

It was another dozens of minutes, and when the effect of the anesthetic subsided and Zhang Leyang gradually regained consciousness, he hurriedly spoke, "How are you feeling now?" ”

Although it was only a minor operation, after Zhang Leyang became conscious, he was still sluggish, he didn't react to Huang Jingyao's words, and he opened his mouth and lay on his back and vomited, Huang Jingyao grabbed the prepared tissue to help the kid wipe it, many people are allergic to anesthetics, and they will basically vomit within 24 days after surgery.

This night, Huang Jingyao spent the night in endless busyness, mainly taking care of Zhang Leyang after the operation, and when taking care, he also closely observed the other party's thumb, the fracture that was re-incised by surgery began to grow back after only five or six hours, even if it was one or two millimeters in length, it still made Huang Jingyao happy.

This joy is due to the fact that the thickness and width of the thumb growth are about the same as that of a normal thumb, and it is not as short and short as those failed mice.

If his thumb could grow according to the thickness and width of his eyes all the time, wouldn't it be ......

"Uncle Yao, it seems to have grown, grown, and it hasn't become thinner? Will it succeed this time? Five or six hours later, Zhang Leyang's spirit was much better, mainly because the operation was too small, and he recovered quickly when he was still young and strong.

After recovering a little, he also felt something and became pleasantly surprised.

"It's starting to grow, but it's too early to say this, how do you feel now?" Huang Jingyao's heart was as excited as he was, he really hoped that he could succeed the first time, it was not hopeless, after all, he was fifty percent sure of this operation and medication, and there was half a chance of failure or success.

"It's numb, itchy, it hurts." Zhang Leyang also spoke quickly, "It hurts to drill my heart." ”

"It's impossible for bones to regrow in a short period of time without pain, you have to endure it now, and don't touch the wound easily." Huang Jingyao became solemn, when the severed limbs of mice grow, they basically grow in a state of anesthesia, but people can't, and the anesthetic is used a lot, which is very harmful to the human body, especially the brain.

He had to solemnly admonish Zhang Leyang.

"Don't worry, in order to have my fingers again, I can endure any hardship." Zhang Leyang nodded heavily, looking at the severed finger full of anticipation and longing. (To be continued.) )
