[Naruto: I, Uchiha Ritian, Start Off Showing Off

Transported into the world of Naruto, he becomes a five-year-old kid in the Uchiha Clan.

Other transmigrators endure bitter grudges and swallow humiliation. Ritian immediately binds himself to a god-tier choice system-show off to earn rewards, put people in their place to grow stronger.

Starting out selling ice cream, he takes the Shinobi World by storm with little chakra-powered inventions, building a business empire across the Five Great Nations. He crushes all competition at the Ninja Academy and becomes the youngest jonin in Uchiha history.

Danzo comes after him? He retaliates with economic sanctions, slashing Root's funding by a third. Orochimaru invades? His advance preparations leave Orochimaru so frustrated he questions his life choices. Obito unleashes the Nine-Tails? Minato and his family emerge unscathed, while Obito gets beaten so badly he wonders whether he activated the wrong Sharingan.

The Uchiha Clan Massacre? Not happening. A single "Uchiha Special Administrative Zone" proposal turns the impending massacre into a political chess match. The Uchiha gain autonomy while remaining loyal, and Danzo snaps his cane in fury.

Shisui doesn't have to die. Itachi doesn't have to defect. Sasuke doesn't have to turn to darkness. All by himself, Ritian rewrites the fate of the entire Uchiha Clan.

But the storm is far from over. Akatsuki rises, the Otsutsuki descend, and catastrophe looms over the Shinobi World.

Isshiki? Fight him. Momoshiki? Fight him. The Otsutsuki God? Fight him just the same.

From the tiny pond of the Ninja Academy, he battles his way into the sea of stars surrounding the Otsutsuki homeworld. In the final battle, he uses his own body as a shield against the God Tree's self-destruction, saving the Shinobi World.

Eight years later, he returns to a thriving Konoha, a revitalized Uchiha Clan, and Naruto serving as Hokage.

The system's final choice:

Stay, or go back?

Ritian watches his wife and children laughing and playing beneath the eaves, looks at Itachi and Sasuke training by the village gates, then gazes toward Hokage Rock-

"What a stupid question. Of course I'm staying."

My fate is mine to decide, not Heaven's. Besides, I'm only here to screw Heaven.
