The end of the world is coming, asteroids are impacting, organisms are mutating, and natural disasters are coming. In order to avoid natural disasters and mutated creatures, humans have built cities underground. Fifty years later, various human dungeons have been erected underground. They fight against the sky and beasts, struggling to survive. Ji Chen is a third-class citizen of Tenglong Dungeon. In order to dream of going to the surface, he chose mutant surgery. From then on, he was unable to reproduce. As a result, his love luck system was awakened, allowing him to pursue beautiful women. "System, you're too late. I won't be able to reproduce anymore. What use do I need from you?" [Apocalypse + system + multiple female protagonists]
