"Uh......" Sun Xiaojie didn't expect Tang Yuhang to suddenly come like this, and he was almost out of breath when he was strangled directly......

"It's been a long time," Tang Yuhang let go of Sun Xiaojie with a smile, "I heard that you went to medical school, and you will become a big doctor in the future." ”

"What a big doctor, the hard life of a medical student is just about to begin," Sun Xiaojie smiled, "Let me introduce, this is my sister, Sun Xiaofei." ”

"Hello Sister Xiaofei," Tang Yuhang shook Sun Xiaofei's hand, "I'm Tang Yuhang, Sun Xiaojie's high school classmate." ”

"Hello," Sun Xiaofei responded, "As soon as you were on the news, he told me about your high school every day, and I already know a lot about your black history." As he spoke, he laughed unconsciously.

Sun Xiaofei smiled with delicate makeup and big red lips, extremely sexy, a small black coat on the outside, and a red shirt with a large collar on the inside, and a deep groove could be seen on the chest......

Tang Yuhang is an out-and-out royal sister, and her immunity to this sexy body is almost zero.

"You actually betrayed me!" Tang Yuhang shouted at Sun Xiaojie, but everyone knew that he was joking with the expression on his face.

The three of them ate and chatted, and half an hour passed quickly.

"I heard that Boss Tang, you came to me to ask me to help you do your new experiment, I don't know what kind of experiment it is?" Sun Xiaofei asked first.

"That's right......," Tang Yuhang replied, "I made a prosthetic limb that can be connected to the nerves of the brain, and it is now in the experimental stage." I found a cat with a broken leg, and first tried to see if I could do it with full self-control. I invented a 'neural connection technology' that links nerves and biofibers together in order to ensure the propagation of brain waves. But this requires a skilled veterinarian to do it. ”

After listening to Tang Yuhang's introduction, Sun Xiaofei asked in disbelief: "You mean...... A prosthetic limb that lets the brain take control? The kind that can be controlled? ”

"Yes!" Tang Yuhang nodded, "It's completely controlled by the brainwaves of biological instinct, because I don't want to implant a brainwave amplifier in my brain, so I directly link nerves and biological fibers together." ”

Even Sun Xiaojie, who was sitting next to him, looked at Tang Yuhang with an incredulous expression, although he was not engaged in scientific research, but can this technology really be done now? This is already a cross-generational technology, right?

After listening to Tang Yuhang's explanation, Sun Xiaofei thought about it, nodded and said, "Okay, I'll help you do this experiment." ”

"Then thank you, Sister Xiaofei." Tang Yuhang instantly relaxed a lot.

"You're welcome." Sun Xiaofei showed a charming smile, which made Tang Yuhang throb.

Sun Xiaojie, who was next to him, saw the smile of the old lady and lowered his head helplessly...... It's over, the old lady is going to do something again.

Sun Xiaojie's home is also doing well in Yushan, and Sun Xiaojie can barely be regarded as a rich second generation. Sun Xiaofei is skilled, and she relies on her own ability to buy a car and a house. There is no financial pressure, and Sun Xiaofei is quite unrestrained when she talks about love.

Sun Xiaofei herself is extremely sexy and attractive, and her boyfriends have changed one after another, but it is precisely because she has no financial pressure that every boyfriend Sun Xiaofei talks about is at least attractive in her own eyes.

Sun Xiaojie also noticed that every boyfriend of his sister is basically a high-quality and tasteful high-quality man with no financial pressure. Basically, every one of his sister's ex-boyfriends who became his brother-in-law would feel good. It's a pity that Sun Xiaofei didn't plan to get married too early, so every boyfriend didn't go to the end.

Now that Sun Xiaojie saw Sun Xiaofei's familiar smile, he knew that his sister was probably interested in Tang Yuhang. Although the Sun family has always been very open-minded, and his parents have never urged him, he always feels a little awkward when he thinks that Tang Yuhang is his high school classmate, in case the two of them really have something.

After eating, Sun Xiaofei and Tang Yuhang agreed on a time to do the experiment, and then went home. The sisters and brothers watched Tang Yuhang roar away in an Audi R8, and Sun Xiaojie said in his heart, when can I also drive such a car.

Sun Xiaofei watched Tang Yuhang leave, and her sexy red lips kept a charming smile, which made the doorman at the door of the hotel feel a little stunned...... Later, the siblings took a taxi home.

A few days later, Wang Qianyu informed Tang Yuhang that a thousand miniature sensors had been delivered. Tang Yuhang immediately began the experiment. Originally, Tang Yuhang's plan was to install 600 miniature sensors in the entire mechanical leg, but after experiments, it was found that this seemed to be a bit redundant in the cat's brain, so it was reduced to 400.

These 400 miniature sensors, about half the size of the fingernail of the little finger, are densely installed inside the entire mechanical leg. The production process can be described as extremely complex, and the material of the mechanical leg is a new type of metal synthesized and made by Tang Yuhang himself, and the cost of this kitten's mechanical leg alone exceeds five million soft girl coins.

Liang Yuting and the other three looked at the mechanical leg placed in the middle of the test bench, which was black and flashed with a special luster under the illumination of the laboratory lights. The three of them shouted in their hearts, they really made this thing!

As the three people who participated in it personally, of course they knew what this meant, and among the several technologies used in this mechanical leg, each of them was a cross-era technology, and it was something that should not appear in this era from the inside out.

Tang Yuhang was doing the final test on the computer next to him, Wang Qianyu pushed open the door of the laboratory and walked in, "Boss, your guest is here." ”

"Oh, please let her in." Tang Yuhang replied without replying.

Wang Qianyu said yes and went out, and five minutes later, he walked in with a sexy figure who was not lower than Wang Qianyu in height, convex and backward.

"Sister Xiaofei, welcome." Tang Yuhang stepped forward to say hello.

"Hello Boss Tang." Sun Xiaofei was holding a small box and wearing a white coat with a hem up to her knees. Below is a pair of thicker cropped wide-leg pants, and you can see that there are thicker black leggings on the inside of the legs, and a pair of black high heels on the feet.

The classic combination of black and white all over the body, with the big red lips that are embellished, is still very sexy. The fluffy braid hangs from the right shoulder to the chest, adding a bit of intellectual beauty to the sexy.

After Tang Yuhang introduced several people to each other, he turned his head to Sun Xiaofei and said, "Sister Xiaofei, look at it, this is it." He pointed to the mechanical leg on the test bench.

The moment she saw the mechanical legs, Sun Xiaofei's eyes froze, and after a long time, she turned her head and asked, "Can I ...... Touch it? ”

"Of course!" Tang Yuhang made a gesture of "please", "Originally, I needed you to operate it for a while." ”

Sun Xiaofei gently picked up the mechanical leg on the test bench, looked at it carefully, pointed to the white thread-like thing that extended out and asked, "What is this?" ”

"The cell-grown biofibers extracted from that kitten," Tang explained, "are to connect the biofibers to nerves and tendons to transmit brainwave signals." ”

"But this ......," Sun Xiaofei said embarrassedly, "I haven't had this kind of surgery before, so I don't know where to connect with it." ”

"It's okay," Tang Yuhang said with a smile, "I'll tell you on the side, Sister Xiaofei, you're only responsible for the operation." ”

"Okay!" Sun Xiaofei nodded, it was the first time she had done this kind of surgery, although her skills were very good, she still needed Tang Yuhang to guide her.

"Then we ......," Tang Yuhang asked, "and this begins?" ”

"Okay!" Sun Xiaofei nodded and said she was ready.

Tang Yuhang took Sun Xiaofei to a sealed laboratory of less than 20 square meters that was simply built with tempered glass a few days ago. For Tang Yuhang's laboratory, which occupies almost an entire floor, it is too easy to build a small sealing room like this.

Liang Yuting and the three of them watched outside, and Tang Yuhang and Sun Xiaofei entered the ultraviolet sterilization room at the entrance of the laboratory. Sun Xiaofei opened the box she brought with her, and all kinds of surgical tools were neatly placed inside.

Then, he took off his coat, took out a white coat from the mezzanine of the box, put it on his body, turned his head and asked, "Can Boss Tang be my assistant?" ”

"Absolutely!" Tang Yuhang nodded and said, "As long as you don't think I'm in the way." ”

Entering the laboratory, Sun Xiaofei skillfully placed the kitten on the operating table, and then anesthetized the kitten......

The laboratory is fully transparent, and Liang Yuting and the three of them stood outside watching Sun Xiaofei's skillful operation.

After the kitten was anesthetized, Sun Xiaofei skillfully shaved off the hair on the severed part of the front legs, and then cut the front legs with a scalpel...... Tang Yuhang listened to Sun Xiaofei's command and helped with the equipment, but Tang Yuhang looked calm.

In fact, Tang Yuhang has been very accustomed to this kind of scene, because of the bad growth environment, he has been running around in various laboratories of the University of Technology since he was a child, and occasionally worked as an experimental assistant for some professors when he was in high school.

And during this period, I don't know how many mice and white rabbits were killed by Tang Yuhang's own hands, and they have long been very accustomed to this kind of scene.

After all, the three people outside can be regarded as scientists, and they are not personally involved, so they don't react.

When the kitten's leg was completely opened, Tang Yuhang asked Sun Xiaofei to cut out the designed shape with a small chainsaw on the kitten's leg bone. The cross-section of the whole bone is a little shorter, but it also stands out in a few places, like the kind of clips on Lego bricks.

The shape of the leg bone also matches the core of the mechanical leg, so that they can be stuck to each other like a socket. Tang Yuhang smeared the bone calcium probiotic liquid cultivated a few days ago on the leg bone, and slowly the bone will enlarge slightly, and the part that is combined with the mechanical leg will grow together completely.
