An otaku from the twenty-first world travels to the world of Naruto and becomes an ordinary mortal with no plug-ins, no system, and no blood inheritance limit. Relying on the Black Mao inheritance from his previous life, he refines zombies, ghosts, demons, and Gu in the world of Naruto. He rises from a mortal step by step. Do you open the Eight Gates of Dunjia? Try if you can hurt my Fubone, Tsukuyomi? See if you can resist the thousand-year-old ghost's attack on the wall and summon the beast? Let you feel the bloodline suppression of the mythical beast. If that's not enough, my Gu can control the whole world. Blood inheritance limit? It's just the material for my growth.
