Lin Wan, a modern Michelin-starred chef, was accidentally reborn into the fictional ancient Yin Dynasty and possessed Shen Qinghe, a down-and-out cook. With her modern cooking wisdom and survival skills, she counterattacked in the strict hierarchical catering world, and at the same time she was involved in court intrigues and rivers and lakes disputes. The story uses food as a guide to connect the love-hate entanglements and intertwined fates between the three protagonists - Lin Wan (Shen Qinghe), the cold-faced secret guard Jiang Yan, and the sick and frail prince Pei Zhao.
