Modern elite brother and sister Gu Mingyue and Gu Mingli accidentally traveled to the Yong Dynasty and became the daughters and Hanlin editors of the Right Prime Minister's Mansion. The two are each bound to a special system - Gu Mingyue needs to revitalize the family's huge stock of assets, and Gu Mingli needs to win the emperor's appreciation and reuse. Facing the impending family crisis, the brother and sister teamed up to solve the problem - Gu Mingyue set up industry, resettled the refugees, prepared a hospital to prevent and control the epidemic, and transformed family assets into an industry that benefited the people; Gu Mingli relied on his modern engineering knowledge to control water and build roads, and gradually became a capable minister relied on by the emperor. In the end, the crisis was resolved, and the two also made a career in ancient times.
