My System Feeds on Uchiha

Trapped as Uchiha Jin, a cynical transmigrator in a doomed clan amidst Konoha’s treachery, he despises both sides. Survival in this brutal ninja world, especially for a civilian from a peaceful past, seems impossible. But then, a twisted miracle manifests: the 'Uchiha Filial Son System.' This perverse power grants Jin the complete abilities of any Uchiha who perishes, regardless of how. The more potent the Sharingan, the greater the prowess, the richer the harvest. From a despised \"clan elder\" to a terrifying \"lunatic instructor,\" Jin now ruthlessly pushes young Sasuke and the clan's future generation to their absolute limits. He's not cultivating them for the clan's strength, but for the inevitable day he might \"filial\" them himself. As Konoha tightens its noose and Uchiha's internal strife escalates, Jin prepares for the ultimate harvest. Will his grim ascent lead to the Uchiha's absolute annihilation, or will he become the monster they never saw coming?
