Su Yi, a down-and-out young man, inherits a run-down grocery shop—only to discover a mysterious passage connecting countless worlds. Framed by his ex-girlfriend Zhou Wanqing and burdened with massive debt, he begins trading across realms: exchanging a few rations from a post-apocalyptic wasteland for crates of antiques, and trading snacks in the heavenly realm for miraculous elixirs.
