Warring States Uchiha: My System Is Short-Circuiting

Transported back to the Warring States era, Uchiha Yo finds himself as the older cousin of Uchiha Madara. The annihilation of the clan is not his problem—this brutal age of endless clan wars is the real hell. With Ashura and Indra locked in their eternal cycle of conflict and Black Zetsu pulling strings from the shadows for a millennium, surviving this Otsutsuki family feud seems nearly impossible. Just as Yo resigns himself to fighting tooth and nail for his life, his system activates—but something is clearly wrong. The system orders him to survive a battle against Edo Tensei Madara—except Madara is currently an eleven-year-old brat nearby. It marks a "Jonin-level rogue Konoha ninja" as a target, but the corpse at his feet is clearly a lowly genin. It instructs him to refine chakra by absorbing natural energy—which is just basic chakra extraction. And then it commands him to defeat Otsutsuki Toneri… in the middle of the Warring States period. The final straw: capture the Nine-Tails for a chakra reward. Yo stares at the ordinary one-tailed fox in his arms and falls completely silent. His system isn't just glitching—it's gone haywire.
