During the Qingli period of the Northern Song Dynasty, the troubles on the northwest frontier were still lingering. The imperial court made peace talks on the surface, but in fact, the military rations were empty and the frontier generals were constrained. What really determined the outcome was not the tactics of war on paper, but who could give the soldiers on the front line a safe and hot meal. Yue Xingzhou, a young general from a poor military family, broke into the transportation department's shady scheme of using old grain as new grain while escorting military rations, and was forced to join forces with Pei Zhiji, the eldest daughter of the Pei family. The Pei family belongs to an old tribe in Chang'an and claims to be from the Tang Dynasty. There is a "Shaowei Food List" in their family, which records not only the banquets of the Tang Dynasty, but also practical techniques such as marching, pickling, making cakes, and brewing sauces. While using "Tang Taste" to pry open the doors of the powerful in Bianjing, the two used delicious food and military ration reform to infiltrate the northwest frontier army, and finally turned a grain case into an overall situation that affected the court and border defense.
