Naruto: I Have Lived Forever Since the Warring States Period!

Uchiha's soul traveled through the ninja world and became Uchiha Madara's biological brother. He is familiar with the plot of Naruto, but he chooses to respect the direction of the original work and only protects his family and Konoha at critical moments. The binding system gives him the power of all realms: Thunder Fruit, Zanpakutō, Pokémon, as well as the Eternal Kaleidoscope and the Immortal Body. His strength has reached the sixth level, but he hides it secretly. Together with Madara and Hashirama, he ended the warring states and founded Konoha. When Madara broke with Hashirama's ideals, he was disheartened and went into seclusion; when the night of genocide came, he came out with a thunderbolt, tried the culprits in public, and allowed the Fourth Generation Eye to regain real power. From adopting Uzumaki Kushina, taking care of Tsunade, to serving as the teacher of Class 7, he gradually led the ninja world to unify. When the Fourth War broke out, he exposed the Black Zetsu conspiracy, suppressed Kaguya, and finally traveled around the world with his harem group to see everything in the ninja world compete and live and work in peace and contentment.
