Xiacheng, a coastal city with a population of tens of millions, experiences "border loosening" every thirteen years. When reality overlaps with the "inside", weirdness begins to permeate - the reflection in the mirror blinks before you do, an extra step appears on the stairs out of thin air, and the breath of earth comes from the mouth of the old lady asking for directions late at night.
When detective Lu Chenzhou was investigating three unmotivated suicide cases, he discovered that the victims had all appeared in the same ruins. He assembled a team of seven people: a genius physicist, a psychiatric director, an archivist with a photographic memory, a former war reporter, a supernatural UP host, and a funeral parlor plastic surgeon. This group of people who were "marked" by abnormalities were forced to step into the cracks of cognition.
This is not a story about catching ghosts and exorcising evil spirits, but a battle with fear. Behind every weird puzzle, there is a forgotten obsession. When the truth points to the "thing" underground in Xia City, they must make a choice - to use their truest emotions to seal the nightmare of a city.
Those who survive in the end will forever lose the ability to fear.
