The subway during the evening rush hour was like a sardine can. Shen Yu leaned against the car door, just wanting to go home quickly.
However, when the train passed through an unusually dark tunnel, everything around it changed.
The platform outside the window is deserted and dilapidated, with blood-red lights flashing; the passengers in the carriage have empty eyes and strange behaviors; the cold broadcast repeats the creepy rules:
"Welcome to the Abyss Line, please abide by the passenger regulations and try to survive to the next stop."
The car door opens, and the outside is not a familiar world, but a horrifying replica full of twisted monsters and death traps.
Shen Yu discovered that he had boarded a death train with no end.
The only way to survive is to complete one terrifying mission after another and struggle to survive in the dungeon where the train arrives.
