Ying Xuanjiao, a modern high school student, accidentally traveled through time and became Fusu's sister in the Qin Dynasty. When she first came to the complex palace, she went from panic to calm. After she recognized Fusu, she was determined to help him stabilize his position.
At that time, Zhao Gao and Hu Hai were secretly seeking positions. Ying Xuanjiao cleverly used modern knowledge to make suggestions and recruit talents for Fusu, and also recommended Han Xin to join the Fusu camp. Zhao Gao designed to frame Fusu, and she and Han Xin tried their best to rescue him. The crisis was resolved and their relationship warmed up.
Qin Shihuang was seriously ill, and the conspirators accelerated their efforts to usurp the throne. Ying Xuanjiao united everyone to plan closely and obtained key support from Qin Shihuang's old ministry.

After that, Fusu implemented benevolent government, Ying Xuanjiao and Han Xin cultivated their relationship, and traveled around the world hand in hand.
