Shen Zhiwei was kicked out of the house by her stepmother Shen Mingzhu on a rainy night, leaving only a yellowed recipe in her hand. She accidentally entered the kitchen of the state banquet and used a "green bamboo shoots after rain" to gain a foothold under Lu Jingyao's cold eyes. In order to find out the cause of her father's death, she studied palace cuisine while relying on Zhou Guifang's secret guidance. She discovered that there was an additional clause in the Shen family's "ancestral precepts" hidden in the middle of the recipe - as long as she cooked three lost dishes at the state banquet, she could take home the family property. Shen Yulang delivered key evidence out of guilt, Master Chen finally turned his back, and Shen Zhiwei finally found the truth between the chef and his family.
