In the 20th year of the Republic of China, three bizarre murders occurred in the Shanghai Concession.
The eyes of the deceased were gouged out and replaced with blood-stained paper eyeballs.
Detective Cheng Yiyuan investigated and found that all clues pointed to the abandoned "Tzu Chi Paper Shop".
What's even weirder is that before dying, each deceased person receives a paper man with the same appearance as himself.
In the hands of the paper figures, they all hold a fragment of a pocket watch with a number...
When Cheng Yiyuan put together the pocket watch, the names of all the victims of a massacre ten years ago were engraved on the back of the dial.
