Research and Target

It was a long-overdue, peaceful dream.

It filled the final void deep within Naruto's heart.

Moreover, he had learned from his mother how to open the Eight Trigrams Sealing Style within his body without the need for a 'key.' The sealing techniques accumulated by the Uzumaki Clan over generations, along with arts like the Adamantine Sealing Chains—which were nearly akin to a Kekkei Genkai—could solve not only Naruto's own issues but also Karin's training difficulties.

Over the next few days.

Aside from necessary outings to communicate with his subordinates, particularly Utakata, to deepen their mutual understanding and awareness, Naruto spent the rest of his time in the cabin studying the sealing techniques passed down by his mother, Kushina. The most important part was the Eight Trigrams Sealing Style. As Kushina had previously mentioned, the only reason Naruto could forcibly contain the Three-Tails within his body using a special contract was his powerful physical constitution. Even so, these were two Tailed Beasts—the purest manifestations of chakra, each possessing different 'attributes.' Tailed Beast chakra was inherently corrosive, even when the beasts were deliberately restraining themselves. If not for Naruto's body gradually adapting and the Uzumaki Clan's vitality far exceeding that of an ordinary person, he would never have been able to withstand it. Yet, even with that, this 'crude' method of containment would eventually lead to problems if left unresolved, as the two beasts remained within him. Unless his physical strength improved significantly in the short term, complications were inevitable.

Now, however, having received the sealing techniques from his mother.

These were no longer major issues.

Combining this with his prior knowledge of sealing arts.

And the 'special notes' left behind by Kushina.

Naruto quickly absorbed a portion of the fundamentals, as well as the most important principles for applying sealing techniques.
