Zhen Yuning, a graduate student in the history department, stayed up late at night after finishing her thesis on Yongzheng's harem system. When she opened her eyes, she entered the world of "The Legend of Zhen Huan" and became Zhen Huan's helpless distant cousin - Cong Qipin, who was pushed to a dead end as soon as she entered the palace. Armed with the entire plot of the drama and knowledge of Qing history, he was able to avoid the murderous disaster at the beginning and make his way through the man-eating Forbidden City. She does not engage in internal strife between females and does not rely on the emperor's favor. She first forges a life-and-death pact with Zhen Huan and Shen Meizhuang, exposes the trap of fake pregnancy to compete for favors in advance, and saves Meizhuang who should have died tragically with hatred; she also accurately predicts the evil plans of the Queen and An Lingrong, resolves serial murders time and time again, and walks a tightrope between the two powers of Concubine Hua and the Queen.
From the dilapidated Leng Yuan next to the Leng Palace to the imperial concubine who co-managed the Sixth Palace, she used modern thinking to break through the ancient dilemma. She made precise arrangements in the turmoil of the previous dynasty's inheritance, reached a two-power alliance with Zhen Huan, and rewrote all the difficulties. In the end, in the deep palace where the imperial power was strife, she escaped from the fate of a chess piece and became the real person in charge of the Forbidden City, creating a legend of the Qing palace where the two palaces were equal.
