A modern social beast who believed in "Lingpingxue" traveled through time and became Niu Hulu Qing, the daughter of a minister of the Kangxi Dynasty. She wanted to lose in the draft by relying on her incompetence, but because of her unexpected modern knowledge, she became rich and was recommended by Kangxi to marry the cold-faced fourth prince Yinzhen. After the marriage, her lost modern textbooks became a lever in the fourth master's hands, and the two began a trial and game about secrets, trust and love.
