- World view: There is a mysterious system called "House Number 13", which will pull people into a different space "layer" constructed from urban legends.
- Rules: Each level has unique rules, and breaking the rules will trigger a "punishment". Points can be earned by clearing levels, and points will be erased by the system when they reach zero.
- Two male protagonists:
- Shen Yan: A calm and rational suspense writer, good at logical reasoning.
- Lu Aiheng: A forensic doctor with extraordinary skills, proficient in corpse language and on-site investigation.
- Main goal: Two people partner up to survive in layers of strange spaces and find the truth behind the system.
