Delivery boy Shen Lang's down-and-out gourmet live broadcast accidentally connected to the Qing Dynasty in parallel time and space. That "Longxi old gourmet" who was crazy about buying gifts and giving advice on his cooking skills was actually the ancestor of the imperial kitchen who was exiled in the family tree! As a result, the style of painting suddenly changed: Shen Lang had just been fined by the platform, and his ancestors there taught him how to make a comeback in a palace fight; a plague was rampant over his ancestors' side, and Shen Lang immediately dropped a modern medical guide. When he used a bag of high-yielding potato seeds to help the people in the exiled area survive the famine, the entire ancient court exploded through the "canopy" - are these descendants delivering takeaways, or... National destiny?
