In the foggy city of the Republic of China, the case of a faceless corpse shocked the whole city.
Xiao Chen, the young master of Yizitang, Chen Qiming, the chief detective of the Criminal Investigation Department, and Feng Tinglan, a newspaper reporter, have very different identities, but they are tied together because of the same unsolved case.
The face-changing scene in Sichuan Opera, the fire in the Sanqing class, the empty coffins in mass graves... Each and every one of them points to the old debt from thirty years ago.
The clues are not solved and the case has become a series.
He was poisoned with cold tea, the wealthy businessmen were quartered, and the army was conquered by the river.
Under the water in this foggy city, every case is like fog. It seems to be dispersed, but there are roots underneath.
Rivers and lakes and police uniforms, pens and daggers, how far you can go depends on your ability.
