Wen Si was originally the legitimate daughter of the Duke of Zhenguo. She was favored by her three brothers, but she was misunderstood and killed because of the instigation of her adopted daughter. After her rebirth, she gained space, cut her hair, cut her crown, and broke away from her family. She used her mother's token to ask the emperor to allow her to become a monk, but she was canonized as a saint instead. Later, he met the regent Bei Chenyuan, who learned medicine and made poison. He repeatedly slapped his family members in the face, and the two gradually fell in love. The brothers finally discovered the true face of their adopted daughter and regretted it too much.
