After entering Beijing, Su Yao relied on her medical skills to save the injured prince. However, she was involved in the royal dispute and was made things difficult for the second prince Zhao Xuan. During this period, she had a secret affair with Qin Wang Zhao Yi. The Hou Mansion was wronged, and Su Yao used her wits to work with King Qin to find out the truth and clear the family's grievances.
The emperor chose a concubine for the prince, and Su Yao had no choice but to get involved. Su Yao was framed by Su Waner and the prince's concubine. Fortunately, with the help of Zhao Yi and her friend Zhao Ling'er, she saved the day time and time again. In the battle for the right to inherit the country, Zhao Xuan used all means to suppress Zhao Yi, and Su Yao helped Zhao Yi win support with her modern philosophy of governing the country.

After a life and death battle, Zhao Xuan rebelled and was sentenced to death.
Eventually, Zhao Yi ascended the throne and Su Yao became queen.
