When mysterious dungeons overran the world, ordinary people awakened to supernatural classes, fighting desperately for survival. Chen Lin, a struggling delivery rider, thought he had a chance at a future, until his own fiancée and her powerful backers betrayed him during a dungeon raid, leaving him to die alone in a brutal beginner rift. But death was not his destiny. As his blood pooled in the dirt, Chen Lin awakened a class that defied the laws of the universe, becoming the Sovereign Host of a legendary traveling Inn that exists beyond normal space and time. This mystical sanctuary is a neutral haven that can appear anywhere, attracting exhausted adventurers, ancient cultivators, monstrous beings, and literal gods. By hosting these otherworldly guests, completing hidden system quests, and expanding his establishment, Chen Lin earns precious Golden Gachapon tickets. With each spin, he unlocks reality-bending skills, divine artifacts, loyal mythological companions, and legendary facilities to upgrade his inn. What starts as a humble roadside tent quickly evolves into a majestic, multidimensional sanctuary that influences entire realms. Operating entirely behind the scenes, Chen Lin forges alliances with terrifying cosmic existences and uncovers the dark secrets of the dungeons. While the world thinks he is a forgotten corpse, he is quietly building an unstoppable hidden empire. The stage is set, the guests are arriving, and those who betrayed him are about to find out that the enigmatic Sovereign running the universe's most dangerous inn does not forgive, and he definitely does not forget.
