You suppressed your own Strength while sparring with Kakashi, guiding him to integrate his sword techniques into Chidori.

You noticed that as Kakashi gradually adapted, his strikes grew noticeably sharper. With his palm acting as the blade, his movements became smooth and fluid—so fast and precise in close combat that they were nearly impossible to defend against.

Moreover, when he employed his sword techniques, the glow from within his body suddenly surged. While it didn't match the enhancement seen in Maruboshi Kosuke, it far surpassed that of most ordinary shinobi.

It seemed he could now unleash about 50-60% of his true Strength.

Afterward, you sparred with Might Guy.

Although from the outside, Guy's techniques seemed crude and far less refined than those of shinobi specialized in taijutsu, filled with wild, forceful, heavy-handed moves...

Some of them even looked like techniques you'd find in free pamphlets handed out at tool shops.

Yet within those seemingly simple moves lay a depth far beyond any flashy taijutsu styles. Each movement carried profound understanding and relentless dedication.

Taijutsu had completely permeated the body—and even the soul—of this green beast of Konoha!

Even without activating the Eight Gates, you could see it clearly in the glow his body emitted when he focused solely on taijutsu.

Almost every strike unleashed more than 90% of its full potential. A few of them even hit the full 100% mark—something that astonished even you!

Once he opened the initial Gates of the Eight Gates, he went beyond the 100% limit!

...

〖Day 16〗

You decided to take a break and sort through the insights you'd gained.

You realized that no matter how many techniques you practiced or how perfectly you mastered them, unless they truly blended together into something personal, you'd never forge your own path in taijutsu.

Reflecting on how Might Guy used simple techniques filled with boundless meaning, you came to understand: to pioneer a path in taijutsu, you must first simplify.

Only by removing unnecessary movements and compressing all your understanding of taijutsu into the most commonly used techniques—

—and then training them relentlessly—

Can you finally grasp a personal sense of style and essence!

...

〖Day 17〗

You cast your own Tsukuyomi on yourself, using it to repeatedly train within the illusion, attempting to transfer that training into reality.

But to your disappointment, ocular genjutsu like the Sharingan's abilities offered no shortcuts in this area.

Similarly, Shadow Clones and Wood Clones proved ineffective. A clone is still just a clone—unless you used cell division to truly split your being, which offered some effect... but wasn't significantly better than training with your real body.

Even though you could copy others' techniques and execute them perfectly—

It was all formulaic, a mechanical repetition utterly at odds with the "essence" you were pursuing.

You began to reflect: what truly sets apart those who fully unleash their physical power? Kakashi, Might Guy, Maruboshi Kosuke... and even other exceptional shinobi in Konoha?

It became clear—the key difference lies in devoting themselves entirely to a single form or technique, integrating it fully into their being.

A state often described as "becoming one with the sword."

...

〖Day 18〗

You visited Might Guy and Kakashi.

Not only were you warmly welcomed, but they also allowed you to observe their taijutsu training.

From Kakashi's father's notes and Guy's family records on the Eight Gates, you found a recurring theme: Will.

To refine taijutsu or kenjutsu to its pinnacle—so that those alone could make someone a formidable shinobi—what mattered most was discovering the "Will" one pursued.

Might Guy's was Youth.

For Kakashi, it was once a cold-hearted focus on completing missions at any cost, even if it meant sacrificing teammates. But the present Kakashi had long abandoned both swordsmanship and that mindset.

Then there was Maruboshi Kosuke, who refused to accept promotion to Jōnin and continued taking on missions while others retired to enjoy family or elder positions in the village.

Will—perhaps more accurately described as obsession.

Yet you understood this was only the key to unlocking physical potential.

The true reason these individuals could express their strength so fully, with such presence and flair in every movement—

Was something else.

A vague, almost mystical concept you decided to call: "Realm of Intent."

Whether with sword or fists, this intangible force arises through years of repetition, as the body and soul continuously synchronize—

Eventually creating a resonance that releases the full potential hidden within the flesh. That's what you call Realm of Intent.

...

〖Day 19〗

Using the Void Rule, you rendered yourself completely invisible and casually strolled into the Hyuga Clan's main house archives, past a sea of Byakugan users.

There, you memorized and practiced all the materials related to Gentle Fist.

You discovered that true Gentle Fist actually contains methods for cultivating the Realm of Intent—and they were surprisingly detailed.

Those who attained this were even granted a special title: "Heavenly Shinobi."

Main family or branch family—it didn't matter. If one became a Heavenly Shinobi, they were no longer bound by clan laws and enjoyed the same status as the clan head.

However, for reasons unknown, the era of Heavenly Shinobi in the Hyuga Clan was lost to time. The means to cultivate the Realm of Intent within Gentle Fist had become a lost art, with only fragmented phrases remaining in the clan's inherited texts.

Today, branch family members can't access the full teachings, and the main family lacks the dedication to pursue it.

Currently, only Hyuga Neji possesses the obsession and clarity of mind required to comprehend the Realm of Intent.

The essence of Gentle Fist has truly faded into history.

...

〖Day 20〗

Based on the information you gathered, you boldly set your personal obsession as: "Invincibility."

It would serve as the ladder to unlock the Realm of Intent and realize your full potential. A clumsy method perhaps—but one that works.

Just like Might Guy.

You compiled all the sword and taijutsu knowledge you'd collected in Konoha into a manual, categorizing it into three main styles: Iron Fist Style, Gentle Fist Style, and Swordsmanship Essentials.

You then set off for the Land of Iron.

You knew that among the samurai there, some still refused to use chakra—yet through sheer understanding and training in kenjutsu, they possessed power rivaling elite jōnin.

From them, you might catch a glimpse of what true Realm of Intent really looks like.

...

〖Day 21〗

Your Mantis returned, laden with materials collected from the Land of Water.

Among them were over a thousand unique bloodlines, alongside highly condensed and refined bloodline essences.

Even you were slightly surprised that so many special bloodlines could be gathered in under a month.

But then again, the Land of Water is the richest region in the shinobi world when it comes to Kekkei Genkai.

And truthfully, less than 1% of the population are actual shinobi. The vast majority of people—though they may carry unique bloodlines—live ordinary lives, never extracting chakra in their entire lifetime.

Thanks to the specialized enhancements of your Mantis clone, it had an extreme sensitivity to bloodlines, enabling it to instinctively sense these individuals' uniqueness...
