Zhang Xiao had an unforgettable experience in ancient times. Even if she is as smart as she is, can she really not take a second look at a man who looks exactly like Fourth Master again? Those dark and sinister decades gave her precious things, but also became a burden that she could not let go of. If she could travel back again, would she choose to return to the palace to stay with Fourth Master?
The modern man who looks like Fourth Master is named Luo Si. More than 20 years ago, first my father disappeared, and then my mother disappeared. All the questions focus on the Mulan teacup cherished by Emperor Yongzheng. Legend has it that this teacup is related to a treasure. The key to solving the problem is those two lines of poetry: "Drinking in the morning makes the Mulan fall, and eating the autumn chrysanthemum in the evening." At this time, a picture of Kangxi playing chess and music with his elders in his later years appeared. In the painting, a magnolia hosta worn by a palace maid attracted people's attention. Luo Si happens to meet a strange girl who seems to be inextricably linked to all mysteries. . .
In order to explore the mystery of his parents' disappearance, Luo Si built a time shuttle. Can he go back twenty years ago and save his parents in distress? Can he return to the Qing Dynasty and solve the mystery of Mulan's tea cup? What happened between him and Zhang Xiao?
As for our Fourth Master, who stayed in the Qing Dynasty and suffered even more hardships, can we travel through time to modern times, meet Zhang Xiao again, get rid of the shackles of the hateful feudal society, and get together and fall in love?
Just as everything was unraveling, an evil web had already been laid out for them. . . .
