During the Yongle period, bizarre murders occurred one after another in Jinling City, the capital of the Ming Dynasty. A child from a prominent family died in a secret room with strange runes all over his body; the courtesan of a brothel disappeared mysteriously, but appeared in the city as a puppet a few days later; and a court official was found in his study room, bleeding from his orifices. The death was horrific, but there was no trace of struggle, as if he died voluntarily. Rumors abounded that it was caused by demons, and the gods and ghosts were unpredictable.
Shen Changfeng, a junior official in the Criminal Department, a seemingly unruly but thoughtful case-solving genius, was involved in this fog. He is burdened with the shadow of an old family case and is suspicious of strange forces and chaos in the world. He firmly believes that behind all visions, there are human traces. Faced with the doubts of his boss, the constraints of Jin Yiwei, and the secret prying of Dongchang, Shen Changfeng relied on his extraordinary observation and reasoning skills to peel off the cocoons, trying to find out from the seemingly unsolvable "gods and ghosts" case, human greed, power struggle, and the undercurrent hidden under the prosperous Ming Dynasty. Can he clear away the fog, reveal the hidden truth, and bring peace to Jinling City?
