In the countryside, there are countless customs, and nine out of ten come with taboos.
Weddings and funerals, ancestral rites and returning home, night roads over mountains, ancient trees at village entrances, and ghostly crossings at bridgeheads.
Chen Yan is a folk-custom mediator with a modest reputation in the city.
Others fear ghosts, pay their respects to them, and dread spirits.
He alone refuses to believe in the supernatural.
In three years on the job, he has handled over a hundred strange folk incidents. He believes only in human malice, harmful old customs, disturbed magnetic fields, and psychological illusions.
There are no ghosts in this world. Fear comes from within.
That is the truth he has always believed in.
But then one deadly folk taboo after another, passed down for centuries, comes true, and inexplicable paranormal events unfold before his very eyes.
All scientific explanations, psychological theories, and folk logic crumble.
For the first time, this calm and rational young man develops the greatest doubt of his life.
Those that harm people, wander about, possess others, and claim lives...
Are they really just illusions of the human mind?
Or...
Are there truly things in this world that the living cannot see?
