Dying for My Sister, Reborn in Naruto

His last breath was in a blood-soaked underground fight, a desperate gamble for his dying sister's medical bills. But instead of oblivion, Ye Zi awoke, battered and starving, in a child's emaciated body, lost in a war-torn, rain-swept world where monstrous snakes and green healing hands defied all logic. Every painful moment screamed: This isn't home. Trapped in a foreign land ruled by terrifying shinobi, he had no chakra, no strength—only an unbreakable will and a mysterious, rapidly regenerating body that baffled even legendary medical ninjas like Tsunade. This dangerous anomaly, an outsider’s unparalleled vitality, immediately caught the predatory eye of the notorious Sannin, Orochimaru, marking Ye Zi as a target and a potential weapon. His sole obsession? To return to his original world, to save his beloved sister. To achieve this, Ye Zi will claw his way to power, manipulating the very shinobi who seek to control him, exploiting their secrets and strength. But what shocking, terrifying truth will he uncover about his own 'unyielding' body when Orochimaru starts to dissect his very being? Will his path home lead to salvation or transform him into something monstrous?
