Most of Tang Yuhang's attention was on Zhao Jianning, who was lying on the operating table, but the corner of his eye occasionally swept to Li Qing and Liu Zhiyun, who always turned their heads to look at the holographic projector next to them from time to time.

In fact, the demonstration just now is a necessary process, and second, it is actually deliberate by Tang Yuhang.

After all, Tang Yuhang wants to make some big moves after Zhao Jianning's matter is over now, so he naturally needs to show his strength.

Now my company has no better products other than a hoverboard, although there is another technology to cooperate with Zhang Kaile and Apple, but after it comes out, it will be a year later.

As expected, Li Qing and Liu Zhiyun were both attracted by this holographic projector. Although Tang Yuhang usually doesn't care about the company's affairs, it doesn't mean that he doesn't understand anything, he knows that sometimes it is necessary to show his strength, after all, his goal is too big, if he wants to reach his sight in a short time as much as possible, he must learn to take shortcuts.

Thinking of this, Tang Yuhang did not observe things outside the operating room, and focused all his attention on Zhao Jianning on the operating table.

Although opening his arm in front to expose the bones was not at all challenging for Li Jianguo, an old doctor who had been operating for many years, due to the environment and the particularity of the patient, his attention was unprecedentedly concentrated, and dense beads of sweat appeared on his forehead.

A female assistant next to him carefully sandwiched the gauze with tweezers to gently help him wipe the beads of sweat off his forehead.

"Zi ......" Li Jianguo held a small chainsaw specially made by Tang Yuhang for this operation, and cut out the required shape on the bone according to the drawn route.

After all the preparations for the current period were completed, Li Jianguo stood up and slowly breathed a sigh of relief, turned his head to look at Tang Yuhang, and nodded lightly.

Tang Yuhang also nodded, walked to Zhao Jianning with the robotic arm, and slowly aimed the protruding points cut out of Zhao Jianning's bones at the inside of the robotic arm, stuck like a clip.

Li Jianguo took out the bone calcium probiotic liquid that Tang Yuhang handed over to him in advance and applied it to the interface between the bone and the robotic arm, and in the future, the bones here will slowly become larger, and they will grow together with the robotic arm completely, as if they have taken root.

"Here, and here!" Tang Yuhang pointed out to Li Jianguo one by one the nerve points to be connected with biological fibers, and Li Jianguo worked with 200% of his spirit to carefully connect every place designated by Tang Yuhang.

Human nerves are a very complex thing, and the slightest carelessness may cause a catastrophe, whether it is Tang Yuhang or Li Jianguo, they dare not make even a little mistake at this time.

Outside, Wang Qianyu's attention was not attracted by the scene in the operating room, and she was very dutifully doing her job - adding water to everyone's cups.

Seeing that it was almost noon, Wang Qianyu didn't ask these people what they wanted to eat, because she could see that they didn't want to eat anything now.

However, whether people eat or not is their business, Wang Qianyu made his own decisions and ordered some simple fast food.

A few people in the operating room were too busy to eat, but they could occasionally take a moment to drink a little water to moisten their throats when they came out of the operating room, and then immediately re-entered the operating room.

Today, I came here with Li Jianguo, an old assistant who has been with Li Jianguo for many years, and the cooperation is very tacit, but even so, the difficulty of this operation is still beyond Li Jianguo's imagination.

According to Tang Yuhang's command, Li Jianguo carefully made a particularly small knot of the specified nerves and biological fibers, then sutured them with soluble sutures, and finally coated them with the potion invented by Tang Yuhang.

This potion can quickly decompose and reassemble the knotted parts to varying degrees, so that the two different things of nerves and biofibers can completely grow into one nerve, and at the same time, it can dissolve the protrusions caused by knots and accelerate the degradation rate of soluble sutures.

Although these biological fibers are not cultivated with Zhao Jianning's own cells, they are still different from nerves in nature, and it is not easy to make two different things grow together completely and become one.

In fact, there are some shortcomings of medical soluble sutures, which can easily cause different degrees of swelling at the implant site and the phenomenon of "aseptic effusion". However, the potion invented by Tang Yuhang prevented this kind of thing from happening.

The people outside the operating room have also been paying attention to the situation inside the operation, and most of the fast food delivered at noon is only a few bites and put aside, focusing all their attention on the operation.

General Zhao himself sat motionless in the chair, the expression on his face could not show his mood, and he looked at the situation in the operating room calmly. However, the fingers that clutched his knees slightly showed his concern.

General Zhao, Zhou Yufang and others were genuinely worried about whether Zhao Jianning's operation would be successful, while Li Qing and Liu Zhiyun were more focused on other aspects of the operation. Success or not, this is already the beginning of a new era.

The people on the outside have their own ideas, and the people on the inside are doing their best to complete the first operation in the history of mankind that perfectly combines man and machine.

At half past seven in the evening, Li Jianguo carefully connected the last nerve and biological fibers, stood up and exhaled a long breath.

Several assistants were also exhausted and breathed a long sigh of relief, and the operation was carried out here, indicating that it was almost completed.

Li Jianguo and several assistants did not rest for too long, and after about ten seconds, they continued to do the final suturing work of the external wound.

Regarding the interface of this arm, Tang Yuhang adopted a wrapping method, which is not a mechanical package of skin, but a skin package of machinery, connecting the interface of the robotic arm with the muscle tissue, and finally wrapping the skin on the robotic arm.

The metal invented by Tang Yuhang has a high fit with the human body, and in the end, the skin and the robotic arm can grow together completely, as if they were born to be one. Li Jianguo originally didn't agree to do this, after all, this kind of thing has exceeded Li Jianguo's understanding.

However, Tang Yuhang promised to give him a detailed explanation afterwards, and Li Jianguo finally chose to believe Tang Yuhang out of trust in General Zhao and Tang Yuhang. According to Tang Yuhang's command, the skin was wrapped in a dark green liquid on the mechanical arm.

After the final operation was completed, Li Jianguo and several assistants completely relaxed their bodies, and they could clearly see that the shoulders of several people had collapsed.

"Uncle Li, please wait a minute, there is one last thing to be done." Saying this, Tang Yuhang took the lead in walking out of the operating room.

The people who were watching outside found that after the operation was over, everyone also exhaled a long breath, and when they heard Tang Yuhang's words, they were suddenly a little puzzled, hasn't the operation been completed? What else is needed?

Tang Yuhang didn't do anything to explain, and after walking out of the operating room, he took out a sealed glass tube from under the test bench on the side. This glass tube is double-layered, with a hollow layer in the middle.

The length is about twenty-five centimeters, and the diameter is about five centimeters, but excluding the double hollow place, the diameter is only about four centimeters, and the two ends are sealed, and inside is a light green liquid that no one has ever seen.

Tang Yuhang put the glass tube on an instrument outside the operating room, placed it vertically, and pressed a button. There was a "snap" of a clip on the top and bottom, and the glass tube was stuck on this oddly shaped machine.

"Uncle Li, you have a needle at hand, please give Brother Ning an injection, just inject it intramuscularly." Tang Yuhang pointed to Li Jianguo's hand.

Although the operating room is soundproof, Tang Yuhang has installed a microphone, and the outside and inside can have conversations.

"What is this?" Li Jianguo held the needle in his hand, looked at the transparent liquid inside, and asked uncertainly.

"Catalyst." Tang Yuhang pointed to the glass tube containing the light green liquid that was placed in the machine next to him just now, "It can make this thing enter the bloodstream and react faster." ”

Li Jianguo also wanted to ask what the light green liquid was, but Tang Yuhang immediately spoke again, "Do as I say first, and then explain when you're done." ”

Hearing Tang Yuhang's words, Li Jianguo looked at General Zhao, and after seeing that the other party nodded slightly, Li Jianguo injected the transparent liquid into the deltoid muscle of his left arm that had just been connected.

"Alright, everybody come out." Seeing that Li Jianguo injected the catalyst into Zhao Jianning's body, Tang Yuhang clapped his hands and said, "Bring everything out, and you can't go in again after you come out." ”

Li Jianguo and a few assistants immediately packed up their things, and after quickly checking what was not missing, they walked out of the operating room.

After the headset reported to Tang Yuhang that the door had been completely locked, Tang Yuhang clicked a few times on the computer next to him, only to see that the liquid in the glass tube containing light green liquid that had just been placed in the strange-shaped machine next to him went down a little bit in an instant.

At the same time, something seemed to open the floor of the operating room, and rows of small holes appeared, and the next moment a light green mist was expelled from these small holes, and in a short time it took over the entire operating room.

The fog is not very thick, although it affects the vision a little, but people outside can still see Zhao Jianning lying in the operating room.

Li Jianguo took a few assistants out of the operating room and sat next to him to rest, while picking up a cup and drinking water.

"Xiaohang," Li Qing came to Tang Yuhang's side, "What is this?" As he spoke, he pointed to the light green liquid that had gone down a little beside him.

"Body Booster!" Tang Yuhang glanced at Li Qing and continued to stare at the mist in the operating room, "It can improve the density and physical fitness of muscles and bones, as well as improve cell activity and accelerate wound healing." ”
