In the third year of Jinghe's reign during the Great Zhou Dynasty, the harem draft came to an end, and the inconspicuous daughter of the Shen family entered the palace as a talented person. She has a quiet temperament and does not like to compete for favor. She only studies and meditates in the peaceful Zhilanxuan every day. She seems to have no sense of existence, but in fact she is thoughtful and good at exploring the truth from clues.
There is no shortage of secrets in the palace, but a seemingly unexpected case of a palace maid falling into the water broke the surface tranquility. The official conclusion was that there was a mistake, but Shen Weiwan accidentally discovered strange pollen in the fingernails of the deceased, which was incompatible with the environment of the crime scene. After that, bizarre events followed one after another: a dancer died suddenly at a banquet, and the imperial doctor diagnosed it as a sudden illness, but she noticed a tiny pinprick behind the earlobe of the deceased; the steward of the library disappeared inexplicably, and the handwriting left behind was mysterious.
There are many factions in the harem, the queen is dignified but hides her schemes, the noble concubines are ruthless in their favor, and the concubines in each palace are fighting openly or secretly. Shen Weiwan's investigations have repeatedly touched the interests of others and led to death. She worked step by step, using her humble position to hide her whereabouts, and dealt with various forces. She not only wanted to uncover the truth about the murder, but also wanted to protect herself in the turbulent palace battle.
As the investigation deepened, she discovered that these seemingly isolated cases were inextricably linked to an old case that had been dusted many years ago. Behind the truth, there are royal secrets and power struggles in the court. Shen Weiwan used wisdom as her blade and calmness as her armor, peeling off threads and cocoons within the unfathomable palace walls to find the hidden truth. In the process, she gradually found her own way of survival.
