In the Northern Song Dynasty, Bianjing was prosperous and the takeout industry was on the rise. {Zhao Xiaoqi} relied on his family's Qinggong to become the fastest delivery man in Bianjing. On the surface, he shuttles through the streets delivering delicious food, but secretly delivers a secret message to the Yue family army - the general's love is hidden in the stuffing of steamed buns and sealed in wine jars. Once while delivering food to Qin Hui's house, he accidentally eavesdropped on Qin Hui's secret conversation with the Jinren and learned of the conspiracy to frame Yue Fei. Zhao Xiaoqi took the risk to deliver the message, but was targeted by Qin Hui's forces and was forced to flee. He used his familiarity with the streets of Bianjing to deal with the pursuers, and joined other deliverymen and salesmen to form a "market intelligence network". He went through hardships and dangers to collect evidence of the crime, and finally handed over the evidence of Qin Hui's crime to an upright official outside the Dali Temple, providing a key force for Yue Fei to clear his grievances.
