As soon as she traveled through time, she faced difficulties from her aunt and sister's schemes, and Su Yao dealt with them cleverly by relying on what she had learned in modern times. At the flower viewing banquet at the palace, she stood out with her own poems, attracting the attention of Prince Xiao Yichen. However, the family fell into factional strife in the court, his father was imprisoned, and the Shangshu Mansion was in danger. Determined to save her father, Su Yao conducted an in-depth investigation and found evidence that the traitor had colluded with the enemy. With the help of Xiao Yichen, she presented the evidence to the emperor, so that the traitor was punished and the family's grievances were cleared.
After that, the relationship between Su Yao and Xiao Yichen warmed up, but their love faced many tests. Not only did there be a royal power struggle, but Xiao Yichen's life experience as an orphan from the previous dynasty also surfaced, which aroused the emperor's fear. In order to protect Su Yao and her relatives, Xiao Yichen was forced to get involved in the battle for the legitimate heir. Su Yao persisted, using modern knowledge to assist Xiao Yichen, dealing with various forces, developing the economy, reforming the military system, and winning the support of the people and the court. In the end, Xiao Yichen successfully ascended the throne and Su Yao was named queen. The two worked together to create a prosperous era of Daqing Dynasty and created a legendary story.
