Naruto: I Adopted Orphan Naruto at the Start with Immortality

(Multiple Heroines) (Overpowered from the Start) (Behind-the-Scenes Mastermind)

An accident sends Shixiu into the world of Naruto-but the timing seems a little off. The bowl-cut kid standing before him says his name is Hashirama Senju, while the kid with the wild punk hairstyle says he's Madara Uchiha.

Just as Shixiu begins questioning his entire existence, he receives the Longevity System. Not only does it grant him an endless lifespan, but it also lets him copy ninjutsu without limit. Any ninjutsu, any kekkei genkai-he can copy them all.

From that day on, Shixiu goes on a ninjutsu-learning frenzy. The Thousand-Armed Buddha? I'll take that. Susanoo? Let's grab it and have some fun.
