Lin Chen, an ordinary social worker, unexpectedly awakened the ability of "Memory Recall of the Dead", but was forced by the mysterious system into the "Seven Days of Purgatory" survival dungeon - a strange secret realm is opened every seven days, with zero error tolerance in the mission, and failure will result in erasure. Only by deciphering the truth of the dungeon can one survive.
In the first dungeon "Blood Apartment", all members were asked to find the murderer who hid the corpse. Teammates were suspicious of each other and were fighting among themselves. Some wanted to use ghosts to get rid of competitors, and some were hiding ulterior secrets. Relying on his ability to trace back, Lin Chen captured key clues from the remaining memory fragments of the deceased, avoiding deadly traps time and time again, and slapping teammates who questioned him. But as the truth approached, he discovered that there was foreshadowing related to his missing sister hidden behind the copy.
Every dungeon is a testing ground for human nature, and every traceback is close to the ultimate conspiracy. When more and more people with strange abilities appear, can Lin Chen stand firm on the edge of life and death and uncover the connection between the system and his sister's disappearance?
