All of humanity is thrown into a doomsday survival world, with people randomly spawning in vastly different deadly environments. Pei Xuan lands on an extremely cold glacier and awakens a unique trading profession. Using extreme-cold ice crystals, he trades supplies with survivors in lava and desert regions, overcoming the initial crisis. He gathers companions, ventures deep into dangerous ruins to collect rare materials, builds a cross-region trading network, constructs floating strongholds, and establishes cooperation with other races. When a global catastrophe sweeps across the land, Pei Xuan faces the world-destroying disaster with the vast resource-trading system he has built from scratch.
