When the first "missing people" appeared in the world, no one knew that they did not disappear.
Instead, he was sent to a place that did not exist in the real world——
Corridor of Annihilation.
There are countless weird copies there:
In the abandoned hospital, there is one less doctor every day.
On the midnight bus, no passengers were seen.
In a century-old house, there is an extra room that does not exist at twelve o'clock every night.
On a desert island, everyone will forget their name.
People who enter the cloister are called walkers.
They must complete dungeon tasks, find hidden rules, and solve death puzzles before they can get the chance to leave.
However, no one knows that behind all the copies, there is a shocking secret:
These so-called "games" are not designed to screen survivors.
Instead, he is looking for someone who can open the "door to the end".
