Su Wan, a top student in modern history, died suddenly while staying up late to review, and his soul traveled to the body of a female scholar in Su Mansion, Jiangzhou, ancient Qing Dynasty, who was set up by her stepmother to break off her engagement. The original owner's mother died young, her father Su Zhengqing was cowardly, and her stepmother Wang and her stepsister Su Qing made things difficult for her, even forcing her to break off the engagement in the name of "Kefu". Su Wan relied on modern learning methods (mind mapping, time management, logical reasoning) to quickly sort out the contents of the imperial examination. On the day of breaking off the engagement, she took out the imperial examination report list and slapped her father and stepmother in the face, and then went to Beijing to prepare for the examination. On the way, she met Gu Zhao, the eldest son of Prince Jing (actually a little boy who was saved by his original owner when he was a child). Gu Zhao looked cold on the surface, but in fact he secretly helped her solve her troubles (preventing her stepmother from sabotaging her registration and finding review materials). Su Wan passed the county examination, the government examination, and the academy examination and became Jieyuan. In the examination, he used modern historical knowledge to defeat the others. In the imperial examination, he won the emperor's appreciation for his "equal land system" policy and was appointed editor of the Hanlin Academy. During this period, the stepmother tried to sabotage the imperial examination, but Su Wan counterattacked with evidence; the stepsister was framed by jealousy, but her own tricks backfired. Gu Zhao gradually revealed his feelings while preparing for the exam, and the two went from testing each other to falling in love sweetly. In the end, Su Wan became an important minister of the court, Gu Zhao succeeded to the throne, and the couple worked together to implement the land equalization system, slapping everyone who had looked down on them in the face, and achieving a counterattack in life.
