Jiang Han, the legitimate daughter of Jiang Lie, the leader of the martial arts alliance, was originally in love with Wu Heng, the son of the general in the town. However, a shocking incident occurred on the day of their wedding. The Wu family was framed as a traitor to the enemy and the whole family was executed. Jiang Han was rescued by his loyal servant who risked his life, and lived in the market incognito. She didn't know that her father's confidant Sima Zhong had already plotted to kill Jiang Lie. He not only seized the position of leader of the martial arts alliance, but also ascended to the position of national advisor, holding the power of the government and the public.
The loyal servant who depended on each other was brutally killed, leaving only the word "Prince" clearly on his palm. Jiang Han mistakenly thought that the Prince was his enemy and vowed to assassinate and take revenge. In order to find out the truth, she changed her name to Su Xi, disguised herself as a palace maid and sneaked into the prince's palace, waiting for an opportunity to file a complaint. However, she was taken in by the ambitious second prince and became his pawn.
During the secret investigation, Jiang Han was shocked to realize that the massacre of the family was caused by the conspiracy between the second prince and Sima Zhong. General Wu was actually the brother of the Queen Mother and the prince's uncle. The prince was also a victim of the conspiracy. The loyal servant's message was originally to guide her to join forces with the prince. Jiang Han, whose heart was filled with despair, did not sink. He was appreciated by the emperor for his superb piano skills, and even met Zhu Chun, the Eight Wise King who could distinguish right from wrong.
Zhu Chun saw through her disguise and changed from testing and exploiting to silently guarding her, accompanying her to dismantle her conspiracy and tear apart her enemies. In the intrigues and intrigues in the court, Jiang Han rises up in the blood and tears. On one side, he is in love with Zhu Chun but does not dare to pull the sadistic heart, on the other side, he is on a determined journey to clean up the grievances between the two families. Finally, with his wisdom and tenacity, he makes his enemies subdue the law and rushes to a new life with his true love.
