Cui Wanwan was originally the legitimate daughter of the Cui family and was loved by all. However, when she was eighteen years old, her family was ruined due to the arrival of the time-traveling female guard Qingyu with the "system". Wei Qingyu used the system to control Cui's father, Cui's mother, and Cui Heng, and killed Cui Wanwan. Cui Wanwan was reborn as a fifteen-year-old with hatred. After rebirth, Cui Wanwan was determined to take revenge. She left home for three years on the pretext of studying art and secretly investigated the truth about the system. During this period, he met Major General Shen Jingzhou, and the two teamed up to kill the Northern Liao spies at the inn, forming their first relationship.
