Yunzhou is huge, big enough to accommodate all dreams and sins.
Yunzhou is also very small, so small that every secret will eventually be put into a package and delivered by the courier.
Li Tiezhu, an unemployed college student, became the "ferryman" of this city.
What he delivered was not just goods.
It is the "filial piety" of an elderly person who lives alone and is deceived, it is the "script" carefully planned by the Internet celebrity anchor, it is the ominous "paper money" in front of the door, it is the non-existent "tenant" in the mirror of the shared apartment...
The station elder Wang always only tells riddles: "The red rope is a signal, you can't jump into the fire pit."
Colleagues each have their own rules for survival, and the police and forensic doctors become unconventional allies.
And Li Tiezhu held half of the "Secret Records of the Streets of Yunzhou" in his hand, traveling through the edge of the law and the gray area of human nature, and gradually understood:
There are no ghosts in this world, but every corner of the human heart may be his next delivery address.
And he must learn how to safely "sign in" this bizarre world.
