Yu Chu, once ranked among the top ten players, unexpectedly becomes a dungeon Boss in an infinite survival game after being resurrected. Armed with her SS-rank talent, she conquers the Shadow Tag and Forest Hunt dungeons in succession, earning impressive scores. While managing her own dungeons and selling dungeon rules for points, she befriends other Bosses, including Jue Xia and Ai Mili. She also resurrects the exceptionally powerful Mo You, recruiting him as a crew member. Along the way, she faces harassment and revenge from a miserly troublemaker, purchases a ship spirit, and sets sail for Aon City, embarking on a brand-new journey of dungeon battles and adventures.
