Genius programmer Lin Jian discovered that she could accurately analyze and reproduce ancient recipes through code. In order to save his ancestral store that was on the verge of bankruptcy, he signed a harsh "private chef" contract with Lu Chenzhou, a technology tycoon who suffered from severe anorexia. He was forced to live in a cold penthouse apartment and cook for him under surveillance. He didn't know that behind this robbery in the name of appetite was Lu Chenzhou's pathological dependence on the "taste" in his hands; nor did he realize that the seemingly ordinary cats, dogs, chickens and ducks in his backyard were actually little monsters who became spirits after the founding of the People's Republic of China and guarded the Lin family's secret recipe for generations. When the code meets the stove fire, when the contract touches the heart, an urban legend about food, healing and protection quietly unfolds between the code and the demonic power.
