Xu Xiyu, who has lost three souls and seven souls, has been stupid since she was a child. Five years ago, she was coaxed by her eccentric parents into taking the blame for her sister and went to jail. Even though he was stupid, Xu Xiyu still studied under him in prison and learned martial arts. Five years later, she was released from prison, but her parents thought she was embarrassed and wanted to send her to a mental hospital. At this time, Li Yanning, the heir to the most wealthy family in Beijing who was engaged to the Xu family, actually found Xu Xiyu to directly obtain a marriage certificate.
