Eldritch Resurgence: I Became the Dark Lord of the Underworld

As eldritch horrors descend and hundreds of ghosts ravage the mortal world, corporate slave Ye Yu accidentally travels to another realm, binding the Underworld Summoning System to become the Dark Lord of the Underworld. He summons Yin deities like Black and White Impermanence and Ox-Head and Horse-Face to restore Underworld order, apprehend malevolent ghosts, and guide souls into reincarnation. While protecting ordinary citizens, he cautiously cooperates with human factions such as the Ghost-Commanders to jointly combat disaster-level eldritch threats, striving to bring peace back to the world.
