Nine Heavens Demon King: Return to Earth

Wu Jin fell into the Nine Heavens Furnace for ten thousand years, devouring countless demons to rise from the weakest human and become the Demon King who commands all demons. Yet power, slaughter, and immortality cannot compare to his longing for earthly life. To return to Earth, he forcibly tore the space-time continuum, only to encounter anomalies on his way back, sealing his transcendent magic and dropping his rank to level 1. Even more absurdly, the familiar Earth has already been transformed with secret realms, monsters, and awakened individuals. Thus, the Demon King who once loomed over the nine heavens must start anew from an E-level secret realm, gradually reclaiming his power through leveling up, hunting, and rediscovering life on Earth.
