Tired of the relentless overtime grind, Lu Mingzhe quits his job and inherits his grandfather’s old restaurant, Five Flavors House. On the night of a full moon, he accidentally activates the ancestral Strange Tales Cookbook and an ancient jade seal, turning the restaurant into a temporal hub connecting the modern city to the Great Sheng Dynasty. As its newly appointed “Gatekeeper,” he uses modern marketing to run the restaurant and make a profit by day, trading for supplies like vitamins, antibiotics, and high-purity salt and sugar.
Under the ironclad rule “No entry without an invitation. Equal exchange,” medicine worth just a few yuan is revered as an elixir. When the ancient jade he traded antibiotics for draws the attention of the modern antiques world, ancient enemies also gather outside the restaurant. The causes and consequences linking the two worlds have long been impossible to disentangle. Should Lu Mingzhe uphold the rules and keep the balance between worlds, or let the collision of civilizations rewrite fate? Between profit and redemption, loneliness and connection, he begins to forge his own path as a Gatekeeper.
