Wang Muxue is the only legitimate daughter of Beiling's young master, Wang Shao'an. When she was born, she was known as a master, and whoever got her could conquer the world. Her father tried his best to hide it, but he never thought that the whole city would know about it. Although she comes from a scholarly family, she has a soft whip. Xiao Yanxiu is the prince of Nanzhao. Due to the decline of his mother's family, he was sent to Beiling as a hostage. In order to return to Nanzhao one day, he has been helping Beiling's prince Zhao Anchuan fight for the throne.
However, Wang Muxue had a soft spot for Xiao Yanxiu. After her proposal was rejected, she followed her father's arrangement to marry Zheng Qiu. However, Zheng Qiu died tragically for no reason. The noble girl in the capital became a slave overnight. In order to quell the rumors, Xiao Yanxiu stepped forward and asked the King of Beiling for a marriage. The two got married as they wished. Wang Muxue spared no effort to help him, but Wang Muxue has not been pregnant for many years. One day, Wang Muxue suddenly found out that she was pregnant. When she was about to tell him the news, she found that Xiao Yanxiu had killed her father and wanted to kill her. Wang Muxue escaped by chance and started on the road to revenge.
