Lin Ye, a down-and-out twenty-four-year-old social media creator, is desperate to revive his paranormal account, suspended after accusations of staging videos. So he risks renting Room 104, a supposedly haunted apartment in the old part of town. A midnight knock, a pale eye beneath the bed, and a soul-subduing talisman on the doorframe force him to confront real evil for the first time. He also unexpectedly reunites with Lao Gui, a mysterious descendant of the Yin-walking tradition.
From a ghost-raising house dating back to the Republic of China era to a corpse-filled well on a campus, from a funeral procession of paper figures to a midnight ghost market, the two are dragged into one eerie mystery after another. The black fibers found in a tenant's disappearance, a bronze mask left behind by an archaeological team, and the curse carried by Lao Gui's family for generations are all closely connected to the mysterious disappearance of Lin Ye's mother years ago.
When a soul-devouring fog envelops the city and the gate between the worlds of yin and yang is about to open, the unlikely partners realize that they are investigating more than urban legends. They are caught in an ultimate struggle over the survival of both worlds. And the childhood trauma Lin Ye has kept buried in his heart holds the key to every mystery.
This horror epic blends modern urban suspense with traditional folk tales of the uncanny. Behind every strange tale lies human greed, along with a glimmer of redemption.
