During a late-night delivery, food deliveryman Qin Xiao unexpectedly awakens the "Myriad Worlds Inventory," which connects him to a vast fantasy world. He discovers that he can not only store the fantasy world's elixirs, imperial scriptures, and divine weapons in the space and bring them back to reality, but can even upgrade its items by spending "bad review/good review points." In a modern city where spiritual energy has yet to return, Qin Xiao uses resources from beyond this dimension to transform himself from an ordinary mortal into the only true immortal in the city.
