I Opened a Pawnshop of All Realms in the Wasteland

Eighty years after the catastrophe, chaebols monopolized water purification, energy and anti-radiation drugs. Chen Yan, a low-level scavenger, owed usury, and his sister was forced into desperation due to radiation sickness. Until he picked up an old-era battery in a garbage dump and accidentally opened the Wanjie Pawn Shop. The junk that no one wants in the wasteland can be exchanged for spiritual liquid in the world of immortality; polluted crystal cores can be exchanged for healing potions in the magic world; old chips, mechanical debris, and glassware can all become bargaining chips in cross-border transactions. Chen Yan started from an abandoned maintenance station and used the resources of the world to save his sister, pay off debts, build a stronghold, and finally tear apart the order of water, medicine and energy monopolized by the chaebol. Others rely on money to become immortals and rely on chaebol to survive. He used rags to open a pawn shop in all realms.
