A modern history enthusiast transmigrates into the Rongguo Mansion as Jia Hu, the legitimate grandson who died young. He knows the entire plot of Dream of the Red Chamber by heart, has a photographic memory, and possesses extraordinary literary talent. From the start, he is weak and near death, the family's decline is beginning to show, and the threat of confiscation looms in the shadows. He proceeds cautiously, revitalizing the family estates, putting its affairs in order, and steering clear of the ruinous extravagance that doomed the family. He makes a name for himself in the imperial examinations, enters government, and uses strategy to change the course of fate. He tenderly protects Lin Daiyu and Xue Baochai, resolving the conflict between the Wood-and-Stone and Gold-and-Jade destinies; saves Yuanchun from the depths of the palace; and shields Tanchun, Yingchun, and Xichun from danger. He takes in Qin Keqing, Wang Xifeng, Shi Xiangyun, and the maids, giving everyone in Dream of the Red Chamber a happier ending. The women fall for him, the harem lives in harmony, and there are no tragedies. In the end, he holds power over the court, restores the Jia family to prosperity, and retires to the countryside with the women he loves, spending his days in poetry and wine and enjoying a life fulfilled.
