I Run the Underworld System

Evan accidentally unlocks the Underworld management system and becomes its new administrator. With the special abilities granted by the system, he recruits assistants including the Hungry Ghost and Stark's soul, helps the wronged soul Zoe get justice through livestreams, and gradually fights against dark forces represented by Hudson. While protecting his friends, Evan grows continuously, resolves countless crises, and transforms from a frustrated young man into a responsible leader.
