After transmigrating to Rocky Mountain in Journey to the West, Chen Xuan awakens the Myriad Realms Shop System. He sets up a stall selling talismans and magical treasures, earning spirit stones to exchange for divine abilities, and hopes to live a carefree life. But every deal changes people's fates and stirs up cause and effect across the Three Realms. He rescues Wukong and foils Red Boy's tribulation, drawing the Tathagata's attention to his little shop. The destined Journey to the West and the grand Investiture of the Gods plot are thrown into chaos by this "businessman." As his shop levels up, the Church of Tongtian forms an alliance, Buddhism strikes back, and demons and monsters covet his wares. He defies heaven through the way of commerce, changing the course of events with every transaction, until he becomes the master of trade across the Three Realms.
