"Here and here, and here and here." Tang Yuhang pointed out to Sun Xiaofei one by one the places that needed to be connected to the nerves.

After all, Sun Xiaofei was the first time to perform prosthetic surgery on animals, and she didn't want to fail the experiment because of her own reasons, so she was very focused, and it didn't take long for dense beads of sweat to appear on her forehead.

Tang Yuhang saw it and carefully helped her wipe the beads of sweat off her forehead little by little. Sun Xiaofei was so focused that she didn't say thank you, but a smile unconsciously appeared on her face.

Carefully pick up one biofiber with tweezers and carefully attach it to the other nerve. Only large nerves can be seen with the naked eye, and small nerves cannot be seen with the naked eye. However, Tang Yuhang was not worried about this at all, as if there was a solution.

Five hours after "......", Sun Xiaofei carefully connected the last biological fiber with the nerve, and breathed a long sigh of relief.

"Sister Xiaofei, I'm sorry for you." Tang Yuhang said with a smile.

"What's the trouble...... Sun Xiaofei smiled and wiped the sweat from her forehead, "If this experiment is really successful, but I still have a share of the credit." ”

After chatting for a few words, Sun Xiaofei continued to do the final work of stitching up the wound, although this was the last thing, but Sun Xiaofei did not relax her attention at all, and did not completely relax until the last wound was stitched up.

"Sister Xiaofei," Tang Yuhang took out a needle, which contained half of a green liquid, "please put this into this cat's veins." ”

"What is this?" Although he knew that this could not be any poison, Sun Xiaofei still habitually asked.

"It's a kind of body enhancement liquid," Tang Yuhang smiled, "It's just a degraded version, which can strengthen physical fitness and speed up wound healing." With the size of this cat, you can come over and have the stitches removed after four days. ”

Sun Xiaofei was dumbfounded when she heard this, and the three people who had been standing outside for five hours were also dumbfounded, although they did see Tang Yuhang fiddling with a bunch of chemicals in the past few days, but they didn't expect to make this thing quietly.

Sun Xiaofei, who was stunned for a while, took the needle from Tang Yuhang's hand and injected the green liquid into the kitten's veins.

After the two people walked out of the laboratory, the three people outside immediately surrounded the two of them with a "whoosh".

Grandma Gong, as a biologist, was particularly excited, "Xiaohang, can that liquid really strengthen the body?" Liang Yuting and Tang Jianjun also stared at Tang Yuhang with a look of surprise.

Tang Yuhang's face showed a very unbeaten smile, "Can it or can't it ......" turned his head to look at the kitten in the laboratory who had not yet woken up, at this time the smile on his face was even more unbeaten, the corners of his mouth were slightly upturned, and his eyes were also looking to the side, like the smiling face of D'Angelo in the online emoji, "Won't you know in a few days?" ”

Sun Xiaofei felt a little tired after five hours of surgery today, and after agreeing to come over and remove the stitches in four days, she said goodbye and left.

The remaining three people still wanted to pull Tang Yuhang and ask something, but Tang Yuhang just didn't say anything with a bad face, and said that he would wait for the results of the experiment to come out. The three of them couldn't help it, so they left Future Technology together.

According to Sun Xiaofei's explanation, Wang Qianyu did not let go of the bandage that tied the kitten, for fear that the movement in the past few days would affect the wound healing. Sun Xiaofei also explained that she couldn't eat in the past few days, just feed some milk.

In the next few days, Tang Yuhang came to the company early every day to check the progress of the experiment, although the kitten could not move, but it did not affect Tang Yuhang's observation with various instruments.

Four days later, Sun Xiaofei came to Tang Yuhang's laboratory again, Liang Yuting and the three of them also came, and Li Yanxin, who received the news, also came over to see the excitement.

A group of people were in Tang Yuhang's laboratory, watching the kitten who was being removed by Sun Xiaofei.

After the kitten finished dismantling the thread, Sun Xiaofei put it on the ground, Tang Yuhang asked Li Yanxin to help get a camera, and Wang Qianyu also helped to get one.

Tang Yuhang squatted down next to him, holding a small piece of dried fish in his hand, "Xiao Huang, come here, ......" said, shaking the small dried fish in his hand from time to time.

Hearing Tang Yuhang's name, the person next to him felt helpless, but now is obviously not the time to pay attention to this, everyone's eyes are firmly fixed on the kitten who is still lying on the ground.

The kitten was attracted by the smell of the dried fish, and slowly stood up and walked towards the dried fish, but just after taking a step, he fell down because he was not used to it.

At this time, the kitten realized that there was something more on his broken leg, and tried to press it with the other leg to remove it, but it soon became clear that it was in vain.

Maybe it was because he had only drunk some milk in the past few days, and he felt hungry, so he slowly stood up and walked towards Tang Yuhang. Because I have broken my leg for a long time, I have adapted to walking on three legs, and now I suddenly have an extra leg, and I always feel uncomfortable and stumble when I walk.

The kitten swayed towards Tang Yuhang, Tang Yuhang bent over and slowly retreated with a small dried fish. The kitten stumbled from the beginning, and slowly became able to walk like a normal cat, and this process took less than twenty seconds.

Everyone's eyes widened and they watched incredulously as the kitten walked towards Tang Yuhang at a pace that was no different from other normal cats.

Tang Yuhang retreated to a table and placed his hand holding the small dried fish on the edge of the table.

The kitten walked under the table and looked up at the small dried fish in Tang Yuhang's hand, and after stopping for a few seconds, he slowly lowered his head, and his two front legs slammed into the table nearly one meter high.

Sun Xiaofei looked at the kitten on the table with a shocked face, at that height, a normal cat can jump on it, but this cat has broken its leg for so long, I didn't expect it to adapt to this prosthesis so quickly.

And the pace is steady, and now there is no feeling of swaying at all, as if that leg was originally his own.

Tang Yuhang first put the small dried fish aside, reached out and picked it up under the kitten's armpit, and checked the place where it was connected to the mechanical legs. But a small detail is not clear to Sun Xiaofei.

Generally speaking, a cat's nails can be contracted and are not usually visible, but when a cat is picked up from under the armpit, it will subconsciously stretch out its paws.

Just when Tang Yuhang picked up the kitten, Sun Xiaofei was surprised to find that there were also claws with cold light stretched out of the mechanical leg.

After looking at it for a while, Tang Yuhang put the kitten on the table again and threw the small dried fish on the ground under the table.

The kitten looked down, and the two front legs slowly hung down first, jumped slightly, and landed firmly on the ground without making a sound. He lowered his head and sniffed the dried fish, and took a bite into his mouth.

Tang Yuhang showed a confident smile on his face, "It's successful." He turned his head to Liang Yuting and the others, who were still a little stunned, "Thank you for your help, the experiment was very successful." ”

Liang Yuting was still staring at the kitten eating dried fish, "I can't believe it now, this thing is really made?" ”

"That's right." Tang Yuhang said with a smile, "And this is indispensable to you, senior sister." Senior sister, your ability is very good, after graduation, if you don't mind, come to Future Technology. ”

As soon as these words came out, Grandma Gong smiled, which shows that Tang Yuhang also truly recognizes the ability of this senior sister, and indirectly shows that the students she teaches are very good.

"Xiaohang," Tang Jianjun asked, "Can this technology be popularized?" There was a look of hope in his eyes, as an old scientist, in fact, his biggest dream is to benefit mankind.

"It's not possible yet," Tang Yuhang shook his head, "You also know that the cost of this cat's mechanical legs has exceeded five million, how big is this?" Next, we are going to make a robotic arm for human use, and the conservative estimate is that the cost is more than 15 million. This is still a situation where there is already a lot of data as well as materials. I am not afraid that no one will want to ......sell this new metal for 100 million yuan for a kilogram alone."

"Alas......" Tang Jianjun sighed, his voice mixed with helplessness. This technology can help many people with disabilities to regain their ability to take care of themselves, but the price is not affordable for ordinary people.

However, Tang Jianjun immediately returned to normal, as a scientist, he knows very well that maybe the new technology has not been used by ordinary people when it first came out, but one day it will drop to the point where most people can get their hands on it.

Tang Yuhang took Li Yanxin's arm and walked to the side, "In a while, you can copy a copy of this experiment record and video and bring it back to your father to see." ”

"What are you going to do?" Li Yanxin turned her head and asked, "It won't be ......"

"Hmm!" Tang Yuhang nodded, "You also know, this time I am doing a robotic arm for a person with a very good background, and I want Uncle Li to do this operation." ”

"Okay...... Li Yanxin smiled a little helplessly, "but I guess he may not dare to take this job." ”

"You must persuade him to go next!" Tang Yuhang said with a smile, "As long as Uncle Li's fame is played out this time, business will be better in the future." Moreover, some of the things I am researching can be used in medical treatment, and in the future, the two of us can cooperate so that the fertilizer and water will not flow into the fields of outsiders. ”

"Okay." Li Yanxin nodded, "I'll go back and talk to him" and then asked, "When will your game helmet be completed?" ”

"Early, wait." Tang Yuhang waved his hand, "I've been very busy lately, this one has to be left behind and slowly improved, and even if it is perfected, it will take more than a year to cooperate with a game company to make a game, so wait slowly." ”

"I'll go!" Li Yan said in her heart, "Originally, my mother thought that she would soon be able to play a game with a sense of more than 100% realism......

Li Yanxin is actually a gamer, and when she spends her days playing with her mobile phone, she has been playing the king pesticide for a long time.
