Infinite Supreme Wizard

A high-level Reincarnator is reborn into the dark world of Harry Potter. He discovers that this world is not simple, so he concentrates on researching dark magic, choosing the path of a Wizard to achieve the realm of a Dark God. In the early stages, he establishes a merchant guild, becomes a professor, molds the power trio, battles the Cthulhu Old Ones and the rulers. After taking over the HP world, he begins to conquer the infinite worlds. I take the heavens as my enemy, I decide my own destiny. I take the earth as my enemy, overcoming all obstacles and moving forward. I take people as my enemy, a hundred ships competing, raising the battle flag high. I take myself as my enemy, constantly striving, surpassing myself, and never stopping.
