The modern girl Bei Jing first traveled through time and became a sadistic little princess. She learned that she would be exchanged for a prince by a civet cat and sold into a brothel. Her voice happened to be heard by her father, Bei Heng. The father and daughter worked together to break the situation and eradicated the usurping forces such as Concubine Ying and Concubine Li as well as the powerful officials who colluded with King Lu. They also reused the talents in agriculture, medicine, chemistry and other fields recommended by Bei Jingchu. They used gunpowder and new weapons to defeat Tuning's foreign enemies. They also promoted the reduction of feudal vassals through favor orders and abolished the ancestral system that prohibited women from serving as officials. In the end, the country of Yue became stronger and stronger, and the grown-up Bei Jingchu was made the crown princess and the future heir of the country of Yue.
