〖Day 28〗

Just like using Truth-Seeking Orbs and Chakra Black Rods, you transformed a Chakra Bead into shackles, layering it with the Rule of Fire and binding it atop the Adamantine Sealing Chains—completely sealing Black Zetsu.

You attempted to interrogate Black Zetsu, but he refused to answer a single question, constantly struggling to escape your seal.

However, due to his unique form, you were unable to conduct either physical or mental torture.

So you decided to postpone the interrogation.

You turned another Chakra Bead into a shell, stuffed Black Zetsu inside, sealed the opening, and with his own strength alone, there was absolutely no way he could break free.

You placed the sealed orb deep in a remote wilderness, left a wood clone marked with the Flying Thunder God technique behind, and returned to the Land of Iron to continue honing your swordsmanship.

...

〖Day 29〗

You felt your understanding of swordsmanship improve.

The street swordsmen could no longer satisfy your need for refinement or the development of your own Realm of Intent.

You shifted your focus and began challenging the top disciples of the most prestigious sword dojos in the area.

In a single day, you defeated dojo after dojo, and with pure technique alone, you managed to battle several headmasters to a draw. Your fame in the region soared to its peak.

That night, you once again questioned Black Zetsu.

Still, he remained silent.

You used your Tenseigan to tear him in half, but all he did was scream before liquefying and reforming as usual.

With no useful results, you sealed him up once again.

...

〖Day 30〗

You were granted an audience with the most respected sword master in the region.

Using your technique to perceive human auras, you sensed his light—it was astoundingly bright.

Though not as dazzling as Might Guy's, he was still the second-brightest individual you had ever encountered.

By your estimation, he could bring out at least 80% of his latent potential!

You suppressed your strength to match his and challenged him to a spar.

As expected, you lost.

Even with the Sharingan's predictive capabilities, he was able to anticipate your moves dozens of steps ahead.

Ironically, your Sharingan's predictions ended up feeding directly into his own foresight…

From him, you learned the essence of what is called swordsmanship!

That night, you interrogated Black Zetsu again.

As expected… still nothing.

...

〖Second Month〗

You stayed with the sword master for over half a month.

Each day, you were defeated dozens of times in sparring—but it helped you become familiar with his style and improve rapidly.

Eventually, during one session, you spotted a tiny flaw in his movement.

You relentlessly pursued that opening, finally knocking the sword from his hand and claiming victory.

However, in the following bouts, he patched the flaw.

You realized it would be impossible to find another such opening in the short term.

And now that you were too familiar with his technique, your rate of improvement noticeably slowed again.

So, after he acknowledged your growth, you chose to leave.

You set out once more across the Land of Iron, seeking other sword masters to spar with, observe, and refine your own style.

Meanwhile, interrogating Black Zetsu had become your daily pastime.

It wasn't fruitless—every time you appeared, Black Zetsu would preemptively say something in Kaguya's defense.

But aside from that, he still refused to share any real intel…

...

〖Third Month〗

You began challenging dojo masters across the region.

At the same time, you took out Uchiha Madara's manuscript, looted during the battle with Obito, and began reading through it.

You transcribed the useful jutsu into a pocket notebook you carried.

You also studied techniques related to swordsmanship, war fans, and scythes. Though not all sword-related, they still involved weapon mastery and could be translated into your own style.

Not to mention, your weapon—the Scythe of Death—was a scythe, making these lessons particularly relevant.

While you spent most of your time cultivating your swordsmanship...

You didn't let up on interrogating Black Zetsu. But credit where it's due: the ancient bastard had a will of steel, still refusing to give you anything of value.

...

〖Fourth Month〗

Your understanding of swordsmanship saw major breakthroughs during sparring.

At this point, even if you suppressed your stats to that of an untrained civilian, your comprehension of swordsmanship alone allowed you to defeat most dojo heads.

Victory after victory sharpened your technique and deepened your insight.

You began forming your own interpretation of the sword.

This insight may seem simple, but without extraordinary talent and relentless effort to draw from many styles, it was impossible to achieve:

On the surface, it appeared you just needed to repeatedly master the basic forms and strike with speed and precision.

But in reality, true swordsmanship required guiding the wrist with Spirit, the blade with the wrist—entering a realm where the sword moved in perfect harmony with your will.

Eventually, the goal was to unify the sword and self.

Even without a blade in hand, your Spirit would contain the essence of a sword.

At that point, you would possess Sword Intent.

Meanwhile, through bits and pieces gathered from Black Zetsu's mutterings during interrogation, you uncovered a major misunderstanding behind his behavior.

Your sudden appearance—killing Obito effortlessly and paralyzing the White Zetsu intel network in Konoha—led Black Zetsu to believe you were a member of the main branch of the Ōtsutsuki clan, sent to investigate the whereabouts of the God Tree's fruit and punish Kaguya.

The speed and efficiency with which you wiped out White Zetsu, and your casual tracking of Black Zetsu, reinforced that theory.

And when you used the Tenseigan to capture him…

You learned from his fragmented words that such ocular power wasn't common among Ōtsutsuki—it was reserved for those who had executed numerous members of their own clan.

That only deepened Black Zetsu's conviction that you were a main-branch executioner tasked with purging defectors.

Naturally, as Kaguya's loyal zealot, he refused to give you a single word.

However, if you really were an Ōtsutsuki executioner, you'd surely know how to break him.

But unfortunately, you weren't.

And you had no idea how to fully utilize the Tenseigan to extract the memories buried in Black Zetsu's festering swamp of a mind.

The interrogation hit a deadlock.

...

〖Fifth Month〗

With no progress in the interrogation, you understood that no matter how much you pushed, you wouldn't be able to pry anything from his iron mouth in the short term.

So you decided to shelve it for now.

After all, the God Tree fruit was safely stored within the prototype Divine Tool of your Divine Domain. It could sit there for as long as you liked.

Instead, you focused on the sword.

Though the progress was slow, it was steady—and you could see the path forward.

Far more reliable than the elusive development of Tenseigan ocular power.

Maybe, just maybe, you'd find a way to break Black Zetsu's will through this path instead…
