Naruto: Awakening Eternal Power with My Eye Techniques

Shortly afterward, Shiyu Uchiha took his leave from General Mifune. With permission granted, he quietly and alone departed from the capital of the Land of Iron, heading toward the Land of Hot Water.

As for Tsubasa Uragawa, Shiyu had already left a letter behind for him. Recently spurred on by Shiyu, Tsubasa had begun secluded training and wouldn't be seen for quite some time.

General Mifune glanced at Shiyu's retreating figure, sensing there was something left unsaid. However, long past the age of curiosity, he chose not to press further. His earlier words were merely an instinctive concern from one warrior for another who possessed an impressive sword technique.

As for the outbreak of the Third Great Ninja War, it would have little effect on the Land of Iron. After all, in the eyes of the Five Great Nations, the Land of Iron's resources were nothing more than a piece of meat not worth fighting over. Moreover, the Land of Iron was neither weak nor strategically important. Therefore, all that was needed was vigilance along the borders to prevent rogue ninja from crossing over; preparations could even wait until after the war actually began.

Of course, this assumed strict neutrality remained intact. Otherwise, the Land of Whirlpool served as a grim example of what could happen.

What General Mifune didn't know was that in Shiyu Uchiha's previous life, the term *Seven Killings* did not merely refer to generals who dominated the world and expanded territory—it also symbolized revolution. In the eyes of those in power, it represented the ultimate rebel archetype.

Shiyu Uchiha felt that since he had come to this world, if the day ever came when his strength proved sufficient, he hoped to reshape the Uchiha clan, Konoha, and the entire Ninja World, putting an end to the never-ending cycle of tragedy and leaving behind something truly his own.

He wished to embody the ancient Confucian maxim: "Cultivate yourself in obscurity; uplift the world when you rise." He truly loved this phrase and made it his guiding principle in this life. Since then, he had felt a newfound clarity in his will.

Another gain Shiyu received during his time with General Mifune of the Land of Iron was access to certain historical records about the Ninja World. Although they weren't original documents but rather scattered fragments, they proved invaluable, offering answers to questions he'd long been seeking.

After departing from the Land of Iron, and since the appointed time with Uchiha Shizhi was still far away—in fact, even Hatake Sumao's (the infamous Copy Ninja) suicide lay well into the future—

he had no rush to return and chose to visit the Star Ninja Village in the Land of Kuma. He was genuinely intrigued by [Kujaku]—after all, it was a flight-enabling secret jutsu, potentially lifesaving in dire situations—though he remained cautious about its side effects. Still, he decided to check it out first before making any decisions.

Currently, his sword techniques had reached a bottleneck; he was just half a step away from breaking through to Kage-level mastery. Fortunately, the most difficult aspect—"Man and Blade Unity"—had already been overcome. The rest would only require patient cultivation to eventually break through.

Therefore, his focus began shifting elsewhere. He pulled out a scroll gifted to him by Uchiha Shizhi when he left the village. It bore a dojutsu seal which could only be unlocked once Shiyu attained a certain level of proficiency in dōkuriki.

Shiyu Uchiha had already reached this stage long ago, back when he combined seated meditation with traditional meditation techniques to push his cultivation further. At that time, however, he focused all his energy on sword techniques and didn't examine it closely. Now was the perfect moment to bring it out.

As his Dōkuriki flowed, the seal left behind by Uchiha Shizhi was easily broken. It was clear his current abilities surpassed the standards set by Shizhi.

Shiyu Uchiha carefully studied the technique and discovered it was a secret jutsu developed based on the Sharingan.

By combining one's own Dōkuriki with chakra, once successfully cultivated, during their fusion not only could chakra control be greatly improved, but the power of one's chakra would see a significant increase.

This was the most common method used by members of the Uchiha Clan in the Warring States Era to break through into Kage-level strength. It did not conflict with traditionally mastering an Ultimate Art and using Five Natures Ninjutsu to reach Kage-level; rather, the two paths complemented each other. Once combined, one could immediately become a powerful figure among Kage-level warriors. It was a shortcut unique to the Uchiha Clan.

There were two prerequisites for cultivation. The first requirement was to reach peak mastery over one chakra nature transformation, approaching the level of a Kage. Naturally, if one had already learned an Ultimate Art, that was even better.

Since this was an exclusive secret jutsu belonging only to the Uchiha Clan, the second condition was naturally having evolved one's Sharingan to at least the third tomoe stage and stabilized the Dōkuriki.

The method involved using chakra nature transformation to resonate with one's own Dōkuriki. By then infusing that Dōkuriki into the chakra, one completed a temporary upgrade of their chakra.

However, like fingerprints, no two people's chakra and Dōkuriki were exactly the same. Therefore, one must determine how far their chakra nature transformation needs to go before resonating with their Dōkuriki. This required constant attempts until personal chakra and Dōkuriki harmonized completely. Without Jonin-level chakra control capabilities, one couldn't even attempt such an operation.

Once chakra and Dōkuriki reached resonance, one could then infuse the Dōkuriki into their chakra up to their physical limit, temporarily enhancing chakra quality.

This state offered benefits including increasing ninjutsu potency while decreasing chakra consumption, and even basic speed and strength would see some improvement. As long as one continued practicing until they could instantly activate this mode, achieving that marked the perfection of the technique.

The downside was that once entering this mode, one could only use that single chakra nature transformation. Although overall power increased significantly, techniques became narrower in scope. Therefore, taijutsu and genjutsu served as excellent complements.

After studying the technique, Shiyu Uchiha realized he was a perfect match for this secret jutsu. Because of his meditation training, his control over both Dōkuriki and chakra was extremely high. Especially regarding mastery of Dōkuriki—his mental state was extremely stable, surpassing ordinary Uchiha clan members by a large margin, making it easier for him to grasp the right timing during cultivation.

Naturally, his stable mental state also drastically reduced the possibility of awakening the Mangekyo Sharingan.

The one unfortunate thing was that the most valuable part of this secret art — the experience records left by predecessors who successfully cultivated it — had been lost. Only scattered fragments remained. Reportedly, Madara Uchiha took away all this valuable knowledge when he left the village.

The Naraka Yomi War wiped out even the walking encyclopedias within the clan, resulting in the total loss of its millennium-old heritage. Only some theoretical knowledge survived, as it had been widely shared and didn't contain any sensitive secrets.

Once he left the Land of Iron, Shiyu Uchiha set his course westward. As he journeyed west, he constantly honed his Fire Release Ninjutsu, deepening his understanding of its techniques. He often meditated deeply on his clan's secret jutsu.
