Reborn in Konoha; I Think I’m Cultivating Immortality

The news of other villages entering the era of their Third Kage barely caused a ripple in Konoha. 

The villagers were preoccupied with adapting to the sweeping changes brought by new policies and had little interest in what was happening elsewhere.

Whether it was a Third Kage or a Fourth Kage taking power, it had nothing to do with Konoha.

Even Hui, upon hearing the news, merely smiled and dismissed it without much thought.

History continued its course. Those individuals rose to leadership in their respective villages, taking the mantle of Kage.

For Hui, this was the best outcome.

Why do you think he spared those people during the last war? It wasn't out of mercy—it was to plant seeds of fear in their hearts. 

Seeds that would grow, ensuring they would carry a lasting dread of him for years to come.

In Hui's eyes, the four great shinobi villages were no longer a threat. His sights were now set on larger ambitions: the Land of Fire and the entire shinobi world.

To Hui, the current system of "one country, one village" was absurd and deeply flawed. Why should powerful shinobi submit to the authority of a daimyo? It made no sense.

In Hui's vision, shinobi villages should be nations in their own right. This was the path forward.

Take the Uzumaki Clan's former homeland, the Land of Whirlpools, as an example. Although it was destroyed due to external enemies, its development as an independent entity had been exemplary.

Alternatively, villages could operate above and apart from nations, with the countries existing solely to support and serve the villages, like the empires and dynasties seen in cultivation fantasy.

In such a model, Konoha would directly appoint the daimyo of the Land of Fire, turning the entire nation into a mechanism that served Konoha's interests.

These two models were, in Hui's mind, the only acceptable paths forward.

Allowing the shinobi villages to be equal to or subordinate to their respective nations was laughable and utterly ridiculous.

Thus, Hui was determined to create a new era. Either the Land of Fire would become "Konoha," or it would be a mere subsidiary of Konoha.

The documents Sakumo Hatake delivered earlier were the starting move in this grand strategy.

Hui's plan was to first infiltrate and control the upper echelons of the Land of Fire's leadership. 

Gradually, shinobi would take over national affairs until the Land of Fire was entirely under Konoha's control.

Of course, Hui could have simply declared outright that Konoha would now rule the Land of Fire, establishing a new order. 

But such an abrupt and drastic approach would undoubtedly lead to bloodshed.

Subtle, gradual change—like water eroding rock—was the optimal path.

Hui had plenty of time fort this project. He could observe the effects of each change and adjust his approach as needed.

The recent scheme by Black Zetsu, however, had reignited a sense of urgency within Hui. 

He was quite eager to enhance his strength further, to at least match the level of Hashirama Senju and Madara Uchiha.

In this era before the arrival of Ōtsutsuki, that level of power would suffice.

The only obstacle preventing Hui from reaching that level was one of raw energy he currently had..

Fortunately, Hui had several methods to address this issue.

The first method was to grow naturally.

His body was constantly evolving, gradually advancing toward a higher lifeform. Given enough time, his internal energy reserves would naturally increase.

However, Hui lacked the luxury of time in that regard.

The second method was to become a jinchuruki.

If Hui were to become a jinchūriki, his chakra capacity issues would be resolved. Additionally, he would gain the ability to transform into a tailed beast. Hui didn't find that transformation interesting though.

As for which tailed beast to choose… Hui's worst-case option would be the Nine-Tails. His ideal choice, however, would be the Ten-Tails.

Capturing all nine-tailed beasts wasn't impossible, after all.

Becoming the Ten-Tails' jinchūriki, however, required the Gedo Statue—the physical vessel of the Ten-Tails.

The statue was currently on the moon. To summon it, Hui would need to manipulate Black Zetsu.

The process was far too troublesome, so Hui wasn't inclined to pursue this option.

The third method was further researching sealing techniques.

One fascinating technique from the original canon was the Yin Seal.

The Yin Seal worked by storing chakra in a diamond-shaped mark on the user's forehead. The stored chakra could then be released all at once using the "Yin Seal: Release" technique.

Hui found the concept interesting and thought of it in terms of water reservoirs:

Imagine the human body as a water tank. Extracting chakra is like adding water to the tank, while using jutsu is like drawing water out. 

The rate of water withdrawal far exceeds the rate of replenishment, causing the tank to quickly empty during battles.

The tank's capacity, however, remains fixed. Any excess water added beyond this capacity is wasted, and once the tank is emptied, it must be refilled from scratch.

The Yin Seal essentially created a secondary tank, increasing total capacity.

For Hui, the solution to his chakra problem was clear: he needed to build additional tanks—or perhaps even a network of such tanks.

However, the Yin Seal had a critical flaw—it couldn't be deactivated, leading to inefficiencies.

As someone skilled in developing new techniques, Hui's first instinct was to improve upon this design.

Perhaps he could create a "Yang Seal" based on the Yin Seal's principles.

With these thoughts in mind—and knowing that sealing techniques were crucial for dealing with Black Zetsu—Hui decided to visit the Uzumaki Clan.

Konoha, Uzumaki Clan Quarters

"Hui-kun, you're really amazing! This is one of our clan's most complex and powerful sealing techniques, and you've mastered it in such a short time!" Uzumaki Mina exclaimed, astonished by Hui's learning ability.

Since the Uzumaki Clan was fully integrated into Konoha, their most prized sealing techniques were gradually being shared with Hui.

Of course, these techniques were only accessible to Hui. No one else was permitted access access them.

"It's nothing, really. Thank you, Mina-nee, for sharing these techniques with me. They've given me a lot of inspiration," Hui replied sincerely.

"I'm glad they've been helpful. To be honest, without you, these techniques might have been lost forever. The younger generation of our clan is showing less and less interest in sealing techniques," Mina said with a sigh.

In the past, back in the Land of Whirlpools, sealing techniques had been the Uzumaki Clan's primary focus due to the scarcity of conventional ninjutsu. 

But after joining Konoha—especially with the advent of the merit-based system—many clan members began favouring ninjutsu over sealing techniques.

Compared to ninjutsu, sealing techniques were far more difficult to master.

To the average Uzumaki, the ancient, powerful sealing techniques Hui was studying seemed almost like arcane scriptures.

Even Mina, a prodigy of the Uzumaki Clan, often found these techniques mind-numbingly complex, and of slept on top of them when studying them.

Hui, upon learning the reason for this decline, was taken aback. After a moment, he could only offer an awkward smile.

This… might really be his fault.
