Indebted youth Chen Mo takes over a desolate shop in the desert. While live-streaming his grievances, he accidentally discovers that the shop can connect ancient and modern times. Ancient people from Tang, Song, and martial arts worlds flock in, and he trades modern food and groceries for gold, silver, and rare treasures. Facing the film city's land requisition and forced relocation, Chen Mo uses his earnings from ancient-modern trade to secure the plot and buy shares in the project. The construction site faces constant trouble, with ancient warrior monks, generals, and imperial guards frequently appearing to help resolve crises. He carefully conceals the cross-time secret, seizes a major borderland order to build a massive business, possesses immense wealth, and guards this unique ancient-modern desert small shop.
