The Strongest Uchiha: Rinnegan Development Plan!

He transmigrates into the Uchiha clan and awakens a Family Prosperity System. To change the clan’s fate of being wiped out by Itachi, Hao begins reforming the Uchiha. He unites the clan, turns their weapons outward, and strengthens its members. Truth lies only at the tip of the sword. Third Hokage: “Why has the Uchiha clan been so quiet lately?” Anbu: “Lord Third, they’ve founded a country!” Third Hokage: “???” Uchiha Madara: “Where’s that brat Nagato? I’m taking back my Rinnegan.” Uchiha Hao: “The Rinnegan? I’ve got a whole pile of them. What style do you want?” Uchiha Madara: “???” The Otsutsuki Clan: “Hand over the Divine Tree fruit and we’ll make your deaths quick.” Uchiha Hao: “Times have changed, old man. Za Warudo!” No female lead for now. The protagonist isn’t mindless or saintly. P.S. Danzo the pot-shadow and the hypocritical Third can both go to hell.
