Xie Guanyue, a modern social animal, traveled through time and became Princess Jing of the Great Zhou Dynasty. She only wanted to live in peace and divorce, but was rejected by the cold-faced prince Xiao Jingxuan and was forced to start a career as a princess. With her modern wisdom, she established her authority in the palace, solved the palace conspiracy, uncovered the truth about her father's injustice, and changed her marriage with Xiao Jingxuan from a marriage of interest to a life-and-death dependence. Faced with power struggles in the court, cults in southern Xinjiang, and border wars, she used modern knowledge to improve ordnance, implement the New Deal, form a navy, and help Xiao Jingxuan ascend the throne to quell the chaos. The two worked together to eradicate the long-standing abuses, conquer the Japanese and open up the sea, and promoted a woman who just wanted to "live a salty life" to the position of a powerful empress who ruled the prosperous age.
