On the night of the genocide, Sasuke fell in a pool of blood, and Obito was peeping in the dark. At this time, Uchiha Itachi's body has been replaced by a soul that knows the entire conspiracy of the ninja world! Suffering from a terminal illness and with less than ten years to live, facing a cruel world where everyone's IQ is online, he decided to play a huge game of chess: break the "one country, one village", abolish the daimyo, and use absolute force to establish a unified "super ninja village"! He lurked in the Akatsuki organization to intercept Hu resources, went crazy with matryoshka dolls, abandoned the drama of mindless revenge, and secretly taught Sasuke the tactics and imperial arts, training him to be the perfect heir to the empire. In the end, he transformed into the most terrifying dictatorial tyrant in the ninja world and single-handedly challenged the entire ninja coalition. "I will bear all the infamy and die with a smile on my face. And you, my dear brother, will step on the tyrant's bones and be crowned king, ushering in eternal peace!"
