At the end of the Eastern Han Dynasty, Jiang Hua, the daughter of a grain merchant in Jincheng County, was punished by a fire from heaven and accidentally got involved in a time and space rift. She used "Nine Chapters of Arithmetic" to deduce troubled times, used modern technology to improve highland barley cultivation, and established a "neutral granary" at the junction of Qiang and Han that made the princes fearful. When Li Jue's prophetic dream intersects with her historical flashbacks, and when Yuan Shao's olive branch collides with Dong Zhuo's plan to move the capital, this woman whose name has been erased from history books is using food as a blade to write her own legend of the empress in the troubled times of the Three Kingdoms - and all this stems from the yellowed "Jincheng County Chronicles 2023" she brought out from the rift in time and space.
