Naruto, the Savior, Has Fallen. I Go Back in Time to Rewrite History

After transmigrating into the world of Naruto, he becomes a member of the Uchiha clan, with just one year left until the night of the clan’s extermination! Fortunately, Uchiha Cheng awakens the [Parallel Future System]. As long as he connects with versions of himself who “failed and died” in parallel worlds, he can inherit everything they left behind! “Connecting to Future No. 12: Inheriting ‘Anbu Cheng’s’ master-level Fire Release proficiency!” “Connecting to Future No. 33: Acquiring the Lightning Release chakra mode, with speed that outstrips the Raikage!” “Connecting to Future No. 666: Inheriting the ‘King of Rogue Ninja’s’ madness and forbidden techniques. Art is an explosion!” … While Shisui was still agonizing over how to save his clan with Kotoamatsukami, and Itachi was still torn between the village and his people, Uchiha Cheng had already climbed to the pinnacle of the ninja world over countless corpses of himself. Facing Danzo, whose arm was covered in Sharingan, Cheng coolly drew his sword: “Your Sharingan are impressive, but in a moment, they’ll be mine.” In this life, I don’t believe in the Will of Fire. I believe only in the sword in my hand!
