Chakra magnitude is a problem. After all, he does not have an immortal body and there are no tailed beasts in his body.

However, after Uesugi Tetsu learned Yin Seal, as long as he continued to practice the seal and expand the storage volume, it would not be a big problem.

As for medical knowledge, let alone, when he first became a disciple, Uesugi Tsuna forced him to learn a lot of medical books. Although he was not as specialized as his senior sister Shizune, it was not bad.

If his palm magic was not really different from ordinary people, maybe he could really become an excellent medical ninja now, maybe.

"The essence of creating regeneration is actually to accelerate the division of cells and thus achieve the effect of 'life regeneration'. However, too much cell division and too fast will cause the passage of life, so this trick...you should use it with caution!"

Tsunade suddenly became serious and his tone was extremely serious.

Uesugi nodded. He was not unfamiliar with "creation and regeneration", and also knew that the essence of this ninjutsu was based on accelerating cell division to achieve rapid healing.

But he was thinking.

If you have an immortal body, will the accelerated division of this cell have any impact on your life span?

Before he could think about it, Tsunade spoke again.

"There are conditions for teaching you this ninjutsu. If you don't agree, I would rather not teach you."

"What conditions?" Uesugi Tsuki couldn't help but say in a daze.

"Before fifteen years old, you can't use it if you were not a life or death!" Tsunade's face became even more serious.

This is the first time Uesugi Tsuna has seen Tsunade so serious outside the gambling table.

But he was still worried.

I said, teacher, it's not a matter of life and death, who can use this thing if you have nothing to do...

By the way, I still have to try it after learning it. Maybe my immortal body can really ignore the reduction in life span caused by accelerated cell division?

In a person's life, cell division has fixed values. If division is accelerated, it will naturally accelerate aging and thus death.

If the immortal body cannot resist the irreversible damage caused by accelerated cell division, of course he will not use it at will.

"Teacher, I agree! I don't want to become an old man in advance, hehe."

Uesugi Tsuki smiled.

Tsunade reached out and bounced his forehead with a doting look, then smiled and said, "Well, let's start!"

Uesugi: "…"

It hurts a lot!

...

The half-year holiday passed in a flash, but Uesugi Tsuki was not idle for a moment.

After the assessment was over, he learned the psychic arts. After returning from the wet bone forest, he practiced Yin Seal, practiced chakra control, and finally learned the creation and regeneration that he had been thinking about.

However, it is actually only considered an entry-level entry.

As Tsunade said, creation and regeneration are very complicated and cannot be mastered in just one month.

When Uesugi Tsubasa thought of Haruno Sakura later, she followed Tsunade to practice for several years, but she still couldn't even find the threshold.

Although it is just an introduction, Uesugi Tsuki has mastered the skills of cell division and can regenerate and recover in a small way.

In this way, he has the ability to heal himself and can recover from normal even if he is blown into pieces.

It just took more time. After all, he still didn't know the technique of Baihao and could not achieve the effect of chakra explosion in a short period of time.

Speaking of which, Uesugi Tsuki has always had a doubt, the art of the genius...

Could it be the exclusive immortal mode of the Wet Bone Forest?

After all, the Baihao Technique is much similar to other immortal modes, and it is a ninjutsu that increases the strength of chakra and increases the power of ninjutsu.

But Tsunade didn't say it clearly, and he wasn't sure.

"Kimura, if the old man asks after he goes back, you should know what to say, right?"

On the day of returning to the village, Tsunade and Shizushi sent Uesugi Tetsu to the outside of the town together.

Tsunade made a special explanation.

Uesugi nodded: "Don't worry, teacher, I'm all proficient."

Tsunade nodded slightly: "That's good... Go back, don't carry your practice, I will have to take the exam in a while."

Uesugi Tsuki smiled and said, "I understand, teacher... Then I'll leave, goodbye to the teacher, goodbye to the senior sister."

Waving his hand, Uesugi Tetsu turned around and headed westward, heading towards Konoha.

Looking at Uesugi Tetsu's departure back, Silent sighed and whispered: "My junior brother has learned even the seal of Yin and the creation and regeneration, but I haven't even mastered the magic of palms..."

Tsunade patted Shizune's shoulder and said, "Well, starting today, I need to practice hard."

Jing Yin was stunned when she heard this, then nodded excitedly: "Yes! Master Tsunade!"

Tsunade nodded and said, "Yeah! Then start with the 'Haikawa Gambling Hall'!"

Mute: "…"

It turns out I am the clown.

...

After returning to Konoha, Uesugi Takashi discovered that Konoha had changed his world.

Due to the issue of war reparations, the third generation of Sarutobi Hirazo had lost his prestige among the senior management in the village.

Although the result was good, Iwaii did abide by the covenant and no longer took the initiative to attack Konoha, but refusing to pay compensation for war did cause Konoha to lose a large amount of development funds.

Moreover, some radicals of Iwaii still acted without regard to the agreement of the covenant and attacked Konoha without authorization.

Although the war ended, the fight never stopped.

Because of this, Sarutobi Hitomi had no choice but to pass the position of Naruto to Hatsuki Mizuno.

In the Third Ninja World War, the combat and command skills of Habuki Mizuno were very impressive.

When Sarutobi Hinaru recommended his successor to the fourth generation of Naruto, there were not many oppositions in the village.

The only variables are Danzo and Orochimaru.

These two people have their own ulterior motives, one covets power and the other covets freedom of experimentation, neither of them is easy.

They all knew very well that the reason why the third generation pushed the Bofeng Mizuno to the top was because Bofeng Mizuno was more obedient.

But Uesugi Tsuki is temporarily outside the vortex and is very unconscious of all this.

What he cares about was that he did not have time to return to the village and participate in the succession ceremony for the four generations.

It is worth mentioning that after Uesugi Tetsu returned to the village, he learned about Kushina's pregnancy.

Danger is gradually approaching.

"Really?" Uesugi Toru pretended to be surprised.

"Yes, not long ago... I didn't expect that one day, I would be a mother." Kushina's face was filled with the glory of happiness, and she secretly glanced at Minato beside her.

"Luckily, Tetsu came back in time. Although I didn't catch up with my succession ceremony, I could see the birth of the baby." Minato looked back at Kushina, and the two met with each other and smiled happily.

Uesugi: "…"

Hello, when can you two change your habit of showing off your dog food?

"By the way, when the child grows up, I want Toru to be his teacher." Minato smiled slightly and looked at Uesugi Tsuki.

"Hey?!" Uesugi Tsuki was stunned.

I'll go, isn't the Prince's instructor Kakashi?
