The "liminal city" is a furnace of thought created by advanced civilization, which maintains its operation by absorbing the spiritual energy of human beings in their extreme state. Each copy is a distorted reproduction of a certain historical fragment of earth's civilization.
Participants will obtain the "memory engraving" ability (read the residual memory of items), but after using it, they will randomly forget a certain memory of their own. There are "scavengers" in the system who are responsible for clearing abnormal data.
The system has a "seven-day reincarnation" mechanism, which resets all copies every seven days. But the protagonists discover that some NPCs retain memories, suggesting that the system is collapsing.
Interpol Pei Changan was involved in the liminal city while investigating a serial disappearance case, and met the mysterious young man Lin Muyun in the "Red Wedding" copy. Lin Muyun showed amazing fighting power but claimed to have lost his memory.
