Konoha: This Uchiha is extremely sneaky

Chapter 20 Clarification

"Yes! If everything goes as smoothly as Toshiro said, that would be wonderful!" She had put so much effort into this new drug. It would be such a waste if it could only be used within the family.

"Don't worry, Mika-nee! Both the village and the clan will benefit from this. I believe neither the Third Generation nor Chief Shigeyama will refuse such a good thing!"

For any undertaking to succeed, multiple stakeholders are involved. If a result that satisfies everyone cannot be achieved, it often ends in failure.

The current head of the Uchiha Shigeyama clan, and one of the graduates of the Ninja Academy. He succeeded to the position of clan head after the untimely death of the Second Hokage's disciple, Uchiha Kagami.

Over the years, they have been working hard to maintain the relationship between the village and their clan. At the same time, they have been trying to reduce the negative impact caused by their clan's "rogue ninja" ancestor, hoping to return to the center of power in Konoha.

Speaking of my clan's "Dancing King" ancestor, he's really a handful. Not only did he defect after Konoha was founded, but a few years later he even commanded the Nine-Tails in a legendary battle against the First Hokage—a battle known throughout the ninja world—and ultimately lost…

The impact on the family was extremely negative. Under the deliberate manipulation of certain individuals, the three Mangekyou Sharingan users within the family engaged in an unprecedented civil war.

The clan's power plummeted, and the Second Hokage seized this opportunity. Using the actions of some ancestor as a pretext, he kicked the clan out of the center of power in Konoha.

Uchiha Toshiro had every reason to believe that if Konoha hadn't been less than ten years old at the time, and the major ninja clans hadn't truly pledged their allegiance, the Uchiha clan's fate wouldn't have been as simple as just being removed from the center of power! Even so, the clan would have been carrying a 'time bomb'.

After dinner, Uchiha Mika was heading to her study to work on her newly developed drug when she was stopped by Uchiha Toshiro, who was sitting on the sofa.

"Wait a minute, Mika-nee, I have something I'd like to ask you!"

"Hey! Since a year ago, Toshiro has hardly taught me anything! Is there something he doesn't understand?"

With the knowledge he gained from his previous life, aside from the initial six months after his transmigration, and after gradually poring over his family's books and Uchiha Mika's old ninja academy textbooks, his understanding of chakra, this supernatural power, had surpassed that of an ordinary ninja.

"It's about physical activation. As a special medical jonin, I believe Mika-nee can give me excellent advice on this!"

"Physical activation? But at Toshiro's age, it's too early to think about that..."

"I'm just doing some thorough research in advance to prepare for the actual activation of my body in the future."

Hearing this, Uchiha Mika was not surprised. This child was always so thoughtful and deliberate in her actions.

"I see! Then, Toshiro, what questions do you have that you can ask your older sister?" She slowly sat down on the sofa, pulled Toshiro Uchiha into her arms, and rubbed against him affectionately.

Inhaling the intoxicating fragrance, Uchiha Toshiro felt a sense of helplessness. While he enjoyed it immensely, where was his dignity as a man?

She had no ulterior motives. As the youngest sister in the family, Uchiha Mika originally lived with her uncle, Uchiha Toshiro, after the deaths of her parents. However, after her brother's marriage, feeling like a third wheel, Uchiha Mika moved in with him. The two of them lived together, somewhat dependent on each other. Uchiha Toshiro gradually came to regard her as true family.

Unlike other time travelers, they did not have to live alone.

Fear of having their secrets discovered.

Having lived two lives, he knew all too well the loneliness and solitude of living alone. Humans are social animals; both men and women need the companionship of family, friends, and lovers.

"Actually, Toshiro's daily chakra refinement and condensation is the simplest form of physical activation!"

With Mika Uchiha's explanation, Toshiro Uchiha gained a deeper understanding of the profound application of chakra, such as physical activation.

The so-called physical activation is a sophisticated application of using chakra, a supernatural power, to nourish and stimulate the body or body tissues to achieve a similar strengthening effect.

The Inuzuka clan in the original work is a good example.

Their clan members cultivate their olfactory system using chakra, granting them exceptional olfactory abilities. Furthermore, they can use chakra to further stimulate their olfactory system when needed, multiplying their abilities.

However, chakra, as an energy, does not come from nothing. Just as a person cannot lift themselves up by their own hair, a ninja cannot extensively utilize chakra, which is composed of their own physical and spiritual energy, to cultivate and nurture themselves on a large scale.

The only way to strengthen a certain part or system of the body is through the two most primitive methods: eating and hibernation.

Premature exposure to physical activation can easily lead to irreversible mistakes due to limitations in experience and control.

Pushing one's body too hard in childhood can have irreversible consequences for future growth and development, with a huge impact on adulthood. That's why major ninja clans don't pass on this skill to their children too early.

People usually start trying these things gradually after they turn ten...

This is the typical path to becoming stronger for a ninja. After the age of ten, they gradually accumulate chakra, slowly nurturing and stimulating their bodies to allow their strength to grow in tandem.

In contrast, there is the special existence of "Jinchūriki". They use the chakra leaked from the "Tailed Beasts" sealed within their bodies as nourishment, naturally activating their physical bodies and comprehensively enhancing their overall physical abilities.

The same principle applies to refining chakra and allowing it to naturally dissipate throughout the body, except that the amount of chakra dissipated is much smaller.

One method uses self-refined chakra as energy, carefully controlling it step by step. The other uses the chakra leaking from the 'Tailed Beast' within the body as energy, allowing it to naturally dissipate throughout the body.

These are the two main ways to revitalize the body. One is slow, meticulous, but highly targeted. The other is rough, permissive, but comprehensive.

Thinking back to the original work, it seems that this is indeed the case.

The special powers used by the Jinchuriki of each village. Such as Lava Release, Boil Release, and Sand Release are all derived from the activation and modification of the Jinchuriki's body by the chakra leaked from the Tailed Beasts.

"So, Toshiro, there's no need to rush. Wait a few more years, until you're a bit bigger, and then slowly begin this long-term ninja training..."
