Wizard, Starting from Invading Another World

Rogge, who traveled to the wizarding world, not only had a low status, but also had mediocre talent. Rogge originally thought that he could only survive in the wizarding world for the rest of his life, but unexpectedly he awakened the ability to double-travel and entered a new world. Travel back and forth between the wizard world and various other worlds, use the power of the wizard to conquer the other worlds, dominate one side, and then use the resources of the major indigenous worlds to feed yourself and grow rapidly. At some point, Rogge suddenly discovered that wizards were nothing more than that.
