Konoha: Start by Saving Uchiha

In the 48th year of Konoha, my soul has passed through the Uchiha, and there are only three years left before the annihilation of the clan! It started on hellish difficulty, but luckily I had a copy of "The Library of Cause and Effect" in my head! Omniscient and omnipotent, he knows all the ninjutsu and conspiracies of the future! The Third Hokage? Let me expose your hypocrisy to your face! Danzo? I have already memorized the 76 plots you secretly planned! Shisui, Itachi, stop struggling! Follow me, I will lead Uchiha to fight a bloody path to the sky! On the night of genocide, when Black Zetsu and Obito thought they had control of everything... Little do you know, I have laid a dragnet, and the entire ninja world will tremble for Uchiha! I, Kiyoshi Uchiha, am not here to rewrite the plot, but to correct this twisted cause and effect!
