In Chang'an City, mysterious crimes occur frequently. As a young minister of Dali Temple, Song Xi was investigating a bizarre "ghost market transaction" and met Su Yelan, a mysterious woman who was proficient in strange arts. She can understand yin and yang and distinguish evil spirits, but she avoids the government.
At the same time, Xie Wuyou, a romantic and unruly sorcerer, took the initiative to join the game and repeatedly solved strange cases with his mysterious spells, but he always disappeared at critical moments...
When the case involves the secrets of the previous dynasty and the royal conspiracy, the three are forced to join hands, but each has their own agenda. And Songxi's foster sister Lin Qingci, an innocent girl who always appears at the scene of murders, seems to be hiding a more dangerous secret.
The ghosts in Chang'an City are more reasonable than living people.
People's hearts are the most unpredictable when it comes to monsters and demons; when times are prosperous and prosperous, they are the most suitable for doing evil.
The painted beauty knocks on the door at night, and the puppet troupe plays the role of the dead;
The nursery rhyme of the dry well urges people to die, and the bronze mirror reflects the past.
