In the Bingwu Year of the Horse, mysterious cases occur frequently in the capital.
A charred corpse's right hand remains unburned, an unsolved case in an ancient temple, a man being bitten in the mirror of a brothel, a series of blood curses in the academy... One case is more bizarre than the other, and each case is more horrifying than the last.
Lu Mingyuan, the head of the Criminal Department, has a meticulous mind and is good at deducing the truth from the threads of people's hearts; the legendary widow Su Xiaotan has a pair of keen eyes that can listen to the "bone language" of the deceased and is good at hearing grievances from the subtle details of the corpse. Two unrelated people are forced to join forces because of a mysterious suicide note and three strange charred corpses.
From questioning each other to trusting each other in life and death, one of them uses the blade of reasoning to cut through the fog, and the other uses the pen of autopsy to interpret the death rattles. Behind the strange case of corpse burning, there are secrets of the previous dynasty, and under the suspicion of the painted skin, there is an undercurrent in the palace. And when all the clues pointed to the mysterious organization with the crescent cocoon in its right hand, they discovered that they had already stepped into a big net that enveloped the entire Bingwu Year.
Acne crawls under the beauty of the prosperous age, and desires flow freely amid mysterious cases and stories. Let's see how the rational detective and the genius duo work together to solve the mystery and expose the conspiracy in this most bizarre year, and also prove a life-and-death friendship that started between the bones.
Strange cases are chess pieces, and people's hearts are chess pieces. All the changes in the Bingwu Year began with that unburnt right hand.
