In the ten years of the Republic of China, Beiping was in turmoil, warlords were divided, and old and new forces were intertwined. Lin Wei, a graduate student in the history department, accidentally traveled through time and became Gege Zhaohua, the direct descendant of Prince Qing's palace. When he woke up, he found himself in a desperate situation - he was "fallen into water" by the Liu Jia family of Fujin because he refused to marry a cruel warlord as a concubine.
Armed with the knowledge of modern history and psychology, Zhaohua lost his cowardice, worked step by step in the inner house, regained the authority to manage the courtyard, and uncovered Liu Jia's gang members. He secretly laid out a chess game in the military and political circles, using the palace's hidden assets as bargaining chips, and reached a cooperation with the ambitious but peaceful marshal Lu Zhengnian, to jointly fight against Lu Hongkui, who coveted military power, and the undercover southern forces.
From allies who test each other to partners who share life and death, the two work side by side to break through the intrigues of the house and the melee of warlords. Zhaohua not only protected the Wangfu clan, but also used modern ideas to reconcile old and new concepts and promote the development of industry and education. When the truth about time travel and the secret treasure from the previous dynasty surfaced, she put aside her obsession with returning and joined hands with Lu Zhengnian to protect Peiping, writing a legend that combines the love between her children and the responsibility for her family and country in troubled times.
