When the world collapses, power becomes a currency—and abilities can be stolen, swapped, or lost in a heartbeat. Amid the chaos of a ruined civilization, the protagonist discovers a rare loophole: a hidden spatial vault and a chance to exploit the global exchange of supernatural powers. While others fight, betray, and bleed for survival, he quietly scavenges, hoards resources, and grows stronger in the shadows. In a world where noise gets you killed, winning means staying unseen—and letting everyone else destroy each other first.
