Uchiha's Journey to the Heavens

Thirty days countdown to genocide. Uchiha Shihao glanced at the calendar and then at himself in the mirror—— Twelve years old, three magatama, and Chidori Rasengan. The clan calls him a genius. Then he did some math. Opposite was Itachi Uchiha. Tsukuyomi. Amaterasu. Susanoo. His ability is enough to last for about thirty seconds. "Can you win?" When despair reached its peak, the system turned on. There is no mall, no lottery, and no sign-in. Just one function - traveling through the heavens. So he entered the first world. Taisho era, Momoyama. Ghosts eat people. He originally just wanted to do a breathing technique, but he accidentally slaughtered more than a hundred ghosts in the entire Vine Attack Mountain. I picked up a blond junior brother by chance. I was scared to death, but those ears could hear people's hearts. Feng Zhu is not convinced? Beat him until he is convinced. Water column facial paralysis? It's okay, he talks little but can fight. Is there a knife hidden in Chongzhu's smile? Let her see what a vegetative state is Itachi Uchiha looked at his clansman who had fallen from the sky. For the first time, his Mangekyō Sharingan could not understand a person. Starting from the death of ghosts, He has only one principle—— If you can push horizontally, don't make any detours; if you can do it, don't talk nonsense. This is a story of Uchiha packing up the world and crushing the night of genocide.
