When he woke up, Chen Mo found himself lying on a completely unfamiliar bed. Under the pillow, there was only a bronze key engraved with strange runes - 7F-13.
The room has no door. Outside the window is a living abyss that surges, roars, and swallows everything.
The cold electronic screen lights up on the wall:
"Welcome to Abyss Apartments, the 444th resident, Mr. Chen Mo."
"Rule 1: You must return to your room before midnight every day. Those who exceed the time limit will be cleared."
"Rule Two: Don't trust anyone who claims to be a resident. They are lies from the Abyss."
"Rule 3: Those who cannot escape within ten days will have their souls swallowed by the abyss and remain in eternal silence."
…
The ten-day countdown is ticking.
The abyss peers out the window and whispers.
Welcome to Abyss Apartments.
How many days can you survive?
