As a courtesan in Beijing, Fuxue thought that being redeemed by the mysterious "gongzi" with a huge sum of money was the beginning of her getting out of the mire and regaining her new life. Until the moment "he" took off his hat. "He" turned out to be Princess Zhenbei, who was disguised as a man, and Shen Jinghong, the wife of the most trusted King of Zhenbei today. The princess held her chin, and her eyes were filled with tempered flames: "I want you to learn my words and deeds, my handwriting tea skills, and my affection for the prince. From today on, you are me." Fu Xue had no choice. She became the shadow of the princess, trapped in a golden cage, wondering about another person's life day and night. Three months later, Gu Changyuan, the king of Zhenbei, returned in triumph. He has great military exploits and decisive killings. He is the living king of hell that everyone respects, but he only gives his full tenderness to the princess. But when Fu Xue was sent to his bed, in the darkness, the man's hot breath stopped by her ears, and his voice was cold and biting: "You have three kinds of fragrance, but there is no smell of her." "Tell me, where is my princess?" Fu Xue was so frightened that she thought her life was about to end. Unexpectedly, the next day, there was an emergency report from the border. Thirty thousand female soldiers were approaching the city. The general at the head was in silver armor and white robes. His eyebrows and eyebrows were just like those of Princess Zhenbei in her boudoir, but in those eyes, the world was burning. The whole capital was shocked: The gentle and virtuous Princess Zhenbei rebelled? ! Fu Xue, who was forced to be a substitute, trembled as she looked at Prince Crazy Pi who was reading the front line battle report and personally choosing today's jewelry for her. Help! This couple was quarreling, why did they use me, an innocent passerby, as cannon fodder?
