Naruto: On the Clan Massacre Night, the Konoha Village-Building System Arrives

On the night of the Uchiha Clan Massacre, I transmigrated into the body of a seven-year-old boy named Uchiha Kosuke. I thought I could save my life with a System. Instead, its missions are more absurd than the last [Friendship and Peace: Reduce the Uchiha’s hostility toward the Senju]! Then the whole clan gets wiped out, and the mission completes automatically! So “reducing hostility” just means reducing the population, huh?! [Unity and Sacrifice: Kill Hashirama Senju]! Me? Kill Hashirama Senju? The God of Shinobi? Turns out Hashirama is already dead, so the mission completes automatically! At least the rewards are useful: Explosive Tags, soldier pills, a tracking map... After finally escaping into a Uchiha hideout, I get caught red-handed by Obito. With an “Oscar-worthy crying performance,” I make Obito Uchiha break down on the spot. Not only do I survive, I even become one of Obito’s “insiders” in Konoha! Kamui marks, the truth behind the Eye of the Moon, Black Zetsu’s surveillance... Kosuke acts like an innocent child on the surface, while secretly plotting everything.
