Su Qingluan, a talented doctor who was born as a medicine collector, broke into the capital with her medical skills of "living dead human flesh and white bones" and her unique autopsy skills in order to investigate the murder case of her master. When he first arrived in Beijing, he was involved in the bizarre "Case of the Female Corpse in Red" and met Xiao Jiuyan, the cold-faced prince (illegitimate son) who was of royal blood but living among the people and had just been recognized.
The two are civil and military, one medical and the other powerful. Su Qingluan spoke through the corpse and repeatedly solved strange cases in the palace (such as the case of the bewitched concubine, the case of the civet cat in the East Palace, and the case of the dragon robe curse). In Boyun's treacherous harem, she not only did not get swallowed up, but relied on her high IQ to not only clear the suspicion, but also backhandedly sent the concubine who framed her to the cold palace. Externally, Xiao Jiuyan is the "living king of hell" who scares the government and the public, but internally, he is Su Qingluan's full-time knife deliverer. In the end, the two uncovered the shocking secrets of the previous dynasty, cleared the court, and stayed together.
