Naruto: The Abyssal Eye Illuminates, Playing Chess from the Warring States Period

Transported into the war-torn Uchiha clan, he becomes the nephew of the madman Uchiha Madara—Uchiha Sou. Thinking that latching onto a powerful figure would ensure safety, he witnesses the death of Izuna, his uncle's descent into madness, and the rise and fall of Konoha built by idealists... Extreme loss gives birth to ultimate power: a Mangekyo Sharingan that can control causality and peer into the threads of fate!

His left eye, "Yomotsu Hirasaka," can sow the seeds of future events; his right eye, "Omohikane," can harvest the fruits of established outcomes.

From then on, he follows Madara into darkness, not to indulge in illusions, but to use the ninja world as a board and all living beings as pieces: at the Valley of the End, he watches coldly; through three great ninja wars, he secretly plants seeds of discord; Nagato, Obito... all are puppets on his chessboard!

Yet, when he attempts to reshape the world with causality, he discovers that Black Zetsu has been scheming in the shadows for a millennium, the Sage of Six Paths casts a scrutinizing gaze from the Pure Land, and the Ōtsutsuki beyond the stars are eyeing him hungrily...

Facing these layers of traps, Uchiha Sou chuckles lightly, the Rinnegan patterns in his eyes slowly rotating: "Black Zetsu? Merely a pawn. The Sage of Six Paths? An outdated guardian. The Ōtsutsuki? Just distant resources. What I want is to eradicate all the world's evils, to lead this cursed world... to break through the stars and reverse causality!"

This is a story of a time traveler who uses causality as a blade and all beings as chess pieces, journeying from the Warring States period to the stars, ultimately slaying gods and creating a world.
