World view
Shun Chao, an imaginary Eastern Empire.
Here, the four major princely families (Fu, Ying, Pei, and Xu) have no military power but control the court. The harem and concubine system is as strict as iron law. Women's talent and education can change their future, but they cannot buy real freedom.
In order to find out the truth about the sudden death of her sister, Li Mo, a medical girl from a poor family, entered the palace as a promise, but she was involved in the strangulation of three forces——
- Concubine Hui's incense: A box of soothing incense contains evidence of regicide in the Duke's mansion.
- King Qin's Sword: Why did he torture Concubine Shu's beloved cat late at night?
- The Queen's Chess: The deposed queen in the cold palace is rewriting everyone's fate with a cinnabar pen.
Purpose: Survival and resistance in the game of power
