Modern delivery driver Chu Chen accidentally time-travels to Mashan Village in the Great Xia Dynasty. In a desperate situation, he awakens a portable space, which turns out to be a complete modern supermarket! From then on, various resources flow in endlessly. Starting with glazed cups to make his first pot of gold, he transforms the poor mountain village into a renowned prosperous place. The Lord of Qingyun City befriends him, and the Eighth Prince forms a sworn brotherhood with him during his travels. Chu Chen uses modern supplies to help Great Xia rise. With Japanese pirates invading the sea borders externally and barbarian tribes attacking city walls internally, Chu Chen deploys vehicles, guns, and tactics, repeatedly achieving extraordinary military exploits. From a mere gambler to being immensely wealthy, from a single village to influencing the pattern of the entire world, Chu Chen uses a supermarket to shake an entire era.
