A fatal courier sent him into a secret room of infinite reincarnation.
Cao Lan, an ordinary courier, was forcibly bound to a death APP called "Key to the Secret Room" just because he entered a gloomy old house to deliver a package.
The pulsating specimen heart in an abandoned hospital, the monster imitating the human form in the mirror museum, the water ghost seeking life on the sunken cruise ship... Horrible secret rooms that distort reality come one after another, and escape is the only way to survive.
When the mobile APP lights up the countdown to the next secret room, can they find their way out of the chase and strange puzzles? And behind all these reincarnations, who are the black hands that control destiny?
