The heroine is Jingshu from Lei Meng's drama New Three Kingdoms. This woman is Sima Yi's concubine and an undercover agent placed by Cao Pi next to Sima.
Therefore, the plot of the story mainly unfolds in the Kingdom of Wei, narrated by the first person, and the reference materials are the original Romance of the Three Kingdoms and two versions of the TV series, as well as the original Romance of the Three Kingdoms.
There may be some non-malicious distortion of historical figures, so please do not take it seriously.
