Lin Xiaoyou, a modern working woman, travels back to the Kangxi period of the Qing Dynasty after an accident and becomes Su Yunwan, a maid of the Ministry of Internal Affairs. With modern knowledge, workplace wisdom and her own "gourmet system", she was promoted from the bottom to the queen in the crisis-ridden harem, and started a ridiculous but affectionate love story with Kangxi. The main plot is a 6-point sweet-sadistic romance, supplemented by a 4-point sophisticated historical background of the Kangxi Dynasty, and the writing style focuses on lightness and humor.
