My name is Shen Zhiwei. I am the only daughter of an abandoned concubine of the former dynasty. I am now working as an errand in the foggy Zhaojing City. On the surface, I am the youngest female medical officer in the imperial hospital, but in fact I am in charge of the "Hidden Pavilion" - specializing in investigating mysterious cases that are difficult to solve. This world is not peaceful. Every time it is midnight, thick fog rises, living people avoid it, and evil spirits wander around. After a great epidemic thirty years ago, the imperial court secretly set up twelve departments to take care of things that could not be explained by science. Because I was proficient in pharmacology, pulse detection, and some mechanical skills, I was called into the "Lingshu Division" and became a detective traveling between Yin and Yang. We rely on ancient book fragments, astrological deductions, and the last words of the deceased to piece together the truth, often disguising our identities and sneaking into dangerous places. Cases come one after another, but the mystery of the demise of the Feifei clan cannot be avoided. The fog not only traps the city, but also covers people's hearts. And I not only want to solve the case, but also want to get out of this thriller game alive.
