A condemned building by the river in the south of the city, a place of death sealed away by time since the 1990s.
Abandoned for twenty years and untouched by anyone, it holds a sealed cold case involving a mass disappearance, a taboo the whole city refuses to discuss.
Lin Xu, a recent graduate, unexpectedly inherits this condemned building that no one dares go near, and is forced to enter its prison-like confines.
He was an ordinary man of the world, a believer in science and a stickler for logic. But the moment he stepped into the hallway, everything he knew was overturned.
At midnight, knocks sound on empty doors. Ghostly shadows slip through the corridors. The rules are bizarre and impossible to understand, and memories crumble again and again.
The gentle, kind gatekeeper conceals murderous intent. A person consumed by obsession lies in wait in the shadows, silently protecting him. Every vacant room holds an unsolved old case, and every wisp of ghostly air carries an obsession with no answer.
As he investigates the building floor by floor, Lin Xu gradually discovers that the condemned building by the river is no isolated haunt. It is the starting point of a web of darkness stretching across the entire city and reaching throughout the country.
His parents' untimely deaths, his shattered childhood memories, his unusual nature poised between yin and yang, and the fate of guarding the building passed down through generations...
All the scattered pieces will eventually come together to reveal a shocking conspiracy spanning thirty years.
The building's spirit devours people, obsession swallows the world, the cycle never ends, and no one survives.
With fate already written, will he become a puppet of the haunted building, imprisoned there forever? Or will he break the deadlock, defy heaven, and save all living things?
One thought can turn the human world into a realm of ghosts.
