Naruto: the Night of Resurrection and Uchiha Genocide at the Beginning

An Uchiha orphan was reborn on the night of the genocide, and Lin Yin returned with the memory of his previous life as an emergency doctor. There is no system, no cheating, only cell-level chakra perception and forbidden technique medical database. When Itachi slaughters his clan with his sword, steals the Sharingan, and turns the whole village into a chess game, he is neither sad nor happy, nor angry nor hateful. Save water, protect springs, hide fire, and steal forbidden skills. Use the hands of a doctor to change your destiny against the will of heaven, and walk through hell with the power of two Magatama eyes. While others rely on hatred to open their eyes, he relies on saving lives and healing the wounded to evolve; While others sought combat power to break the situation, he used medical skills to overwhelm the ninja world. Danzo covets? Then cut off his claws. Konoha prejudice? Then establish new rules. Chaos in the ninja world? Then use medicine to enter Taoism and reshape the future of Uchiha!
