During this period, Uchiha Shinichi's doctor status seemed very popular. Although the patients treated were all his learning materials, his fame became much bigger.

However, Uchiha Shinyi was not very happy.

Although he still likes to learn these things, the increasing number of patients seriously affected his experimental progress.

Just as Uchiha Shin was thinking about how to solve these problems, Tsunade called Uchiha Shin to Naruto's office.

"I have studied the medicine you drink. It is a very ordinary nutrient solution, but the concentration is too high. This makes me puzzled. According to the physique of a normal person, it should be impossible to absorb so many nutrients. Even if you don't last to death, it will be wasted most of them." Tsunade's expression was a little solemn.

These days, she has been trying to help Uchiha Shinichi solve her physical problems, but the fact is that she has no good idea at all.

"The human body... will grow. Because of the Maneid Sharingan, my body is under great burden."

"So, in order not to be a blind man, I began to try to strengthen my system. The method of strengthening is very simple. Eat! After eating enough nutrients, the body will become stronger under the pressure of the Maneidoscope Sharingan."

"Gradually, my body changes a lot, but the demand for nutrients will increase."

Uchiha Shinichi explained to Tsunade calmly. He had brought all these things to Tsunade, but Tsunade obviously had forgotten them.

Tsunade couldn't help frowning when she heard this. Tsunade actually remembered what Uchiha said in a flash, but she wanted to confirm if there were any other reasons.

In fact, strictly speaking, Uchiha Shunyi's condition is not a disease. He just eats a little more...

"The Manelidian Sharingan is not the only pressure. Since you can open it at any age and have not died yet, it means your body can bear it. It just shouldn't be able to use it, right!"

"What really puts you in this desperate situation should be the chakra extraction that is happening in your body all the time. I'm a little curious. Where did you get so many chakras?"

Tsunade's face was full of incredible expressions.

You should know that the chakra in the ninja's body is not always there. Although some are present in the body, most chakra need to be extracted when used.

Extracting chakra is an instinctive existence for a ninja. When chakra cannot be extracted, which is what the ninja often says, the chakra is exhausted.

But in fact, as long as the ninja is not dead, chakra will not be exhausted. chakra is like a life force to ninjas.

The case that Uchiha Shinyi wants to extract chakra but still can bear has never appeared in the entire ninja world.

It's simply...infinite chakra!

"It's not that magical, it's just a cycle. Because chakra is not consumed, extracting chakra is an instinct for me. Because chakra can enhance my body, the chakra I extract is used to integrate into my body and then extract chakra." Uchiha explained as soon as he spoke.

What Uchiha Shunichi originally wanted to develop was a chakra version of internal strength.

However, this kind of thing is simply impossible, because chakra and internal strength are two completely different things.

So, after some hard work, Uchiha Shinichi successfully developed something that seemed useless, but solved his problem and greatly improved his chakra control.

This is a technique, not a ninjutsu at all.

"You shouldn't be able to stop now! Do you know that if you continue, you will eventually starve to death due to excessive consumption? Even this nutrient solution will not last long."

"You should have less than ten years of life left."

Tsunade's expression was a little solemn. Even she never expected that the situation would have been so bad.

When Uchiha Shin heard Tsunade's words, he was not afraid at all.

"It only takes a while to find a solution to the problem."

"Bang!" Tsunade slapped the table in front of him with a palm, and shouted loudly at Uchiha Shin, "Little kid, do you know, you're going to die!"

"Sigh your voice, of course I know. But now there is no choice, right?" Uchiha instantly rubbed his wrinkled ears and said calmly.

Uchiha's attitude made Tsunade, who was in anger, stunned. Then he seemed to be deflated and said, "Little kid, don't give up your life so easily!"

"Well, I never thought about death. Although I was a little naive at the beginning, I could solve this problem." Uchiha Shinichi was very calm.

Tsunade's eyes looked at Uchiha Shinichi, a little complicated. It seemed that she had recalled something, but it seemed that she was just an ordinary gaze.

"To be honest, I don't have a good solution. Your previous experiments should be trying to clone it! Did he teach you the way Orochimaru's body change method?" Tsunade suddenly asked, pretending to be a little indifferent.

"No, but I know a forbidden technique called the Spiritual Transformation Technique!" Uchiha Shin did not explain what he tried to clone, but just said this simply.

"The Art of Spiritualization... By the way, Mr. Sarutobi once asked you to read the Book of Seals." The moment he heard this ninjutsu, Tsunade was a little dazed, but he recovered in an instant.

"A very creative idea, an exact same body may really succeed. But the probability of this is too small, it is basically impossible to succeed, and cloning the human body?" Tsunade shook her head and said nothing.

Uchiha replied: "I know, but this is the best way I can think of."

Uchiha Shinichi's real purpose is naturally not like this. But this idea did arise, but he thought about using clones as battles instead of replacing the body.

Hearing Uchiha Shunyi's words, Tsunade was a little silent for a moment.

After a while, Tsunade spoke and said, "I have no choice in your body. But I do have a way of thinking, but this way of thinking is very difficult. Even if you show me your genius, it is hard for me to imagine that you can succeed."

"Teacher, do you really have a way?" Uchiha's eyes lit up instantly. Although he could control the state of life through backtracking, it would be better if the problem could be solved.

"You should have seen this thing too - Yin Seal! A secret ninjutsu, and it can only be practiced by women..."
