Chen Mo just got on the last subway train, but was led into a never-ending dark tunnel.
The carriage was empty, the radio was murmuring, and at the end of the tunnel was an entrance that tore apart reality - step by step, he entered a strange world.
Fellow travelers are disappearing, monsters are evolving, and he himself... Seems to be undergoing a transformation.
It is difficult to tell the truth from false dreams, consciousness is fragmented, and more and more clues point to a terrible fact——
Those hands stained with blood, the torn summons, the familiar yet unfamiliar back...
Is he really just "Chen Mo"?
