During the Xuande period of the Ming Dynasty, strange things happened frequently inside and outside the capital. First, a wealthy businessman died mysteriously in a secret room, leaving only half a jade pendant engraved with mysterious symbols. Then, the official silver on the water transport ship disappeared without any trace of prying at the scene. Shen Yan, the official of Jinyiwei, relied on his keen observation and super logical reasoning ability, and was ordered to investigate these difficult cases. During the investigation of the case, he met Su Wanqing, a female doctor with a sassy personality and proficient in the secrets of organs and medical skills. Su Wanqing had been secretly searching for the truth because her family had been involved in an old case. The two had an intersection because of the case. At first, Shen Yan felt that Su Wanqing acted strangely and had a suspicious identity, so he was wary of everything; Su Wanqing thought that Shen Yan was a court eagle and did not want to get involved too much. But with the in-depth investigation of a series of cases, they discovered that behind these seemingly independent cases, there was a huge conspiracy hidden, and it was related to an old case many years ago. The two had to put aside their prejudices and work together to solve puzzles one after another with their own abilities, find clues from the clues, and fight against the enemies hiding in the dark. In the process, they not only have to face complex cases and dangerous enemies, but also face the overt and secret struggles within the court, and finally uncover the conspiracy, restore the truth, and protect the tranquility of the capital.
