A crossover between anime worlds, Infinite Flow, slow burn.
After transmigrating into One Piece, he travels around the East Blue with the Art of Sword Flight. Along the way, he meets the future Straw Hat crew in their younger days and follows the same path they once took. Later, he joins the Navy, his strength skyrockets, and he eats the Rumble-Rumble Fruit. When the future Summit War arrives, he dominates the battlefield. At the cry of “Sword, arise!” ten thousand swords take flight. At the cry of “Heavenly Sword!” even Blackbeard trembles.
Next, he enters Naruto, where the power scale is higher than in One Piece. Carrying all his strength from the One Piece world, he transmigrates into the Naruto world and begins traveling across the shinobi world. He befriends the legendary Sannin and joins Konoha at their invitation, beginning his life as a ninja. He gets along well with the Uchiha and is given a Sharingan. Later, while dealing with Danzo, he obtains First Hokage cells. The Sage's Eye and Sage's Body combine, and the Rinnegan appears. On the night of the Nine-Tails' attack, thunder roars across the sky as a colossal sword cleaves through the heavens and turns the Nine-Tails into a docile little fox. He is the only man who can dance before Uchiha Madara.
I almost died after being attacked by someone and then ran away. I can't say.
Same as AI composition

How is this strength calculated?
It is tasteless to eat and a pity to throw away.
