The real world was falling apart.
The third time Chen Mo saw that black door, he finally reached out and pushed it open.
Beyond it lay a bizarre village holding a harvest festival, an old photo studio where anyone who posed for a picture would die, passengers from different eras riding the subway, and a corpse on the dissection table that opened its eyes. Every instance devoured lives, leaving behind only lost items: a morgue tag that could pause death, a damaged film negative that could erase memories, and a straw effigy that linked two people's fates.
Chen Mo was a forensic pathologist who had entered the door to find his missing fiancée. He should have had to survive alone, but instead he was forced to team up with a retired firefighter, a college student who could communicate with spirits, and a mysterious doctor to clear each stage. Because the horrors inside the door were not limited to monsters. Your teammates might no longer be human.
When the black door began appearing in the real world, when the side effects of the lost items gradually eroded human nature, and when Chen Mo discovered that his fiancée had long since become part of the "door," he had to make one final choice: become the one who opens the door, or become the door itself.
"Welcome. Come on in."
