The realm is at peace, and the Central Plains have been united. Leng Xingchen, the new leader of the Central Plains’ largest martial arts sect, takes Shen Zixin, the Northern Hall Master, as his bride against her will. Shen Zixin pretends to agree while secretly making plans. On their wedding night, she escapes and flees to the Western Regions. By chance, she saves a Turkic prince who is being hunted, and the two endure hardships together on their journey, gradually falling in love. After returning to the Turkic palace, they are caught up in a coup. To protect himself, the prince has no choice but to marry a princess from the Central Plains dynasty. Shen Zixin flees the royal city and saves Li Laosan, the assassin who had been hunting the prince. She persuades him to mend his ways and teaches him military strategy and the arts of divination and tactical formations. Five years later, the Turkic prince has ascended the khan’s throne. He finds Shen Zixin and brings her into the palace as a secondary consort. Shen Zixin follows the khan back for the sake of love, only to discover that he is no longer the kindhearted man he once was, and that he seems to be hiding a massive conspiracy.
