The Rise of the Empire Begins in Konoha

Gen Takashi accidentally traveled to the world of Naruto and discovered that there was a dark space of unknown meaning inside his body. I originally wanted to survive until the end, but in exchange I was assassinated. I don't pretend anymore, I have a dark space, and I have to move ahead in establishing an empire to conquer the ninja world. Established a training base to train an invincible ninja soldier, and participated in three battles. The Jounin of Konoha are all my people. Akatsuki is very powerful, so they shouldn't be angry if I poach their people, right? Uchiha Madara is going to be resurrected? Kaguya Otsutsuki is going to be resurrected? Let them live! Where is my ninjutsu nuke! This work is also known as "I originally wanted to be an emperor but I had to become an emperor" and "It's all the assassins who prevented me from becoming an emperor soon".
