Tong Nuonuo was a little excited by the affirmation of his master and the trust of his good friend. He felt like there was a nail under his butt and he couldn't sit still.

He twisted and turned, secretly peeked at his master's expression, and then looked at Chen Xiao eagerly.

Quezhai looked helplessly at the disciple whose emotions were written all over his face, and said, "Okay, take your friends to your room to talk."

Tong Nuonuo stood up with a delighted look on her face, took Chen Xiao's hand and dragged him towards the door behind the living room, "Come this way, my room is quite big."

Chen Xiao was dragged so hard that he couldn't stand steadily. Xi Yunting, who was beside him, quickly came over and supported his waist.

That position seems normal, but it is actually very abnormal. When most people see someone about to fall, their first reaction is to pull their arms, and few people will directly hold their waists because the posture is too intimate.

Quezhai looked at the four people who were slowly walking away with their backs to him. His eyes wandered between Chen Xiao and Xi Yunting, wondering if there was any special relationship between the two.

But then, he shook his head. These two people didn't look alike at all. One was a casual cultivator and the other was a high-level elite from a large sect. Moreover, there was such a huge difference in their cultivation. It was impossible to think about it.

Quezhai chuckled secretly and felt that he was being very suspicious.

He walked towards his room with his hands behind his back and began to plan to check on his apprentice later in the day to prevent him from getting too excited today and not being able to sleep at night, which would affect his performance tomorrow.

Tong Nuonuo and a few others had already entered the room, and without any polite words, they got straight to work.

He unbuttoned Chen Xiao's shirt, rolled up his right sleeve, and held Chen Xiao's arm to look left and right.

After a while, he nodded: "Li Yuzhou's medicine is very effective. This arm has been regenerated very neatly without any defects. It is quite perfect."

Chen Xiao said: "It's just that the strength is different from other parts of the body, and I'm afraid that there will be differentiation in the future because of this difference."

Tong Nuonuo said: "Although I don't know the specific reason, I think it's because of the special method you practice. But it doesn't matter, just let me make up for this shortcoming." He put down Chen Xiao's arm and turned to search in his mechanism box. "I will take some materials from your right hand and other places to make the original body later."

Jing Hui came close to him and asked curiously: "What do you want to use as the original body? The epidermis?"

Tong Nuonuo glanced at him and held a thin metal rod in his hand with a pointed cone-shaped object on the top.

"It doesn't have to be the epidermis. Any part under the skin will do." Tong Nuonuo stabbed Chen Xiao's arm with the spike, and Chen Xiao felt the pain as if he was bitten by a bug. "Anything inside the flesh, tendons, and bones will do."

Tong Nuonuo took the thing away, and a wound the size of a grain of rice appeared on Chen Xiao's arm.

Xi Yunting's frown finally relaxed a little.

Tong Nuonuo changed to a new spike and stabbed Chen Xiao's other arm again.

Jing Hui couldn't understand his behavior, but Chen Xiao vaguely understood that this was just like going to a hospital or a scientific research organization. Nothing could be more accurate than a blood test.

Tong Nuonuo carefully put the two small spikes into a device and said, "Let me compare the strength of the new body and the original body. Then I can make nourishing liquid based on Xiaoxiao's current body strength."

Chen Xiao was puzzled. "Nutrient fluid? Isn't it used to create tendons, bones, nerves, etc. for replacement?"

Tong Nuonuo patiently explained: "Replacement is also feasible, but the body tissues that are replaced are all based on you, so there is no need to go through an extra procedure, and you can suffer less. However, overall nourishment is more troublesome than manufacturing one by one, and it takes longer."

This even surprised Xi Yunting and Jing Hui.

Xi Yunting said: "I saw in the relevant jade slips that the mechanical alienation of the body must be replaced. Using mechanical puppets to replace the original part does not require this?"

Tong Nuonuo said: "The jade slip you read probably didn't cover too deep of a topic, did it? Xiaoxiao's situation doesn't belong to alienation. What counts as alienation? It's the part that the human body doesn't have. If you want to develop other functions, you have to replace it."

Tong Nuonuo gave an example, "Let's say a puppeteer wants a pair of wings to fly. People don't have wings, so he must make a pair of real, flesh-and-blood wings and connect them at the shoulder blades. The parts made by the puppet mechanism are completely real, and the wings can even connect to the blood vessels inside the body to transport nutrients. But after all, they are not original, so there will be some differences in the operation of the skills."

Xi Yunting relaxed his brows in relief, "I see."

Tong Nuonuo added: "But I heard that if one can successfully ascend to immortality, the body will be reshaped when passing through the thunder tribulation, and the alienated parts will truly become one."

Chen Xiao was amazed as he listened, and at the same time he was full of admiration for Tong Nuonuo.

If Tong Nuonuo's expertise was in the design and manufacture of mechanical weapons, then puppetry was a completely different field of biochemistry. A pair of flesh and blood wings, connected to the human body, without any rejection reaction, must have an extreme understanding of biochemistry to be able to create such a foreign organ.

After Tong Nuonuo's explanation, Chen Xiao immediately understood that the puppet was actually a human clone! The so-called replacement was nothing more than an organ transplant, and the transplanted organ was a cloned organ cultivated from one's own body cells.

Chen Xiao also understood why Quezhai Sanren would not agree with Tong Nuonuo getting in touch with mechanical puppets now, because it was too cross-border.

It is no wonder that the promotion to the Grand Master of Machinery is so difficult, which has stopped most of the Grand Masters of Machinery. It is too difficult for a master's student who originally studied mechanical design to suddenly take the doctoral exam in biological science.

Chen Xiao stroked his chin and watched Tong Nuonuo busying himself, thinking that the reason why Li and Zhou were helpless was because he was just a simple pharmacologist and lacked the analytical skills of Tong Nuonuo.

If Li and Zhou could also judge the strength of the new part and the original body with only two samples, perhaps he could also create a potion with the same effect.

Tong Nuonuo put out a large number of tools at her side, and soon there was no place to step in the room. Chen Xiao, Xi Yunting and Jing Hui had to step back step by step to make room for Tong Nuonuo.

In an instant, the tidy and empty room became messy. Chen Xiao had witnessed Tong Nuonuo's ability to create chaos when they shared a workshop together.

Tong Nuonuo still argued that this is called order in chaos.

Chen Xiao's thoughts drifted to the days when he was refining equipment in the workshop of Chongshan Villa, and he fell into deep thought.

Maybe... he could take this opportunity to do something.

The engineer thought of his body as something that could be transformed and changed, and this idea gave Chen Xiao inspiration.

If he used the puppet-making method to refine the tendons, bones, blood and flesh of his arms with vital energy, then would the circulation of vital energy not be so slow?
