A wasteland world descends, void rifts wreak havoc, and humanity retreats behind high walls. Xu An unexpectedly binds to the “Interdimensional Civilization Community Management System”, treating demon beasts and evil gods as rule‑breaking property owners. Using property enforcement authority, he suppresses powerful enemies and collects property fees. He restores order, demolishes illegal constructions, tames ferocious beasts, and transforms the apocalyptic wasteland into a safe home. Along the way, he confronts demon gods, repels alien races, pacifies chaos, and single‑handedly upgrades Blue Star into a demonstration zone of universal civilization, protecting the safety of humanity and all creatures, playing out a hilarious yet fiery legend of property management in the apocalypse.
