When Lin Ran woke up, he found himself trapped in a strange world shrouded in thick fog, holding a piece of paper with "rules" written on it: Don't look directly at the shadow, knock on the ground three times every ten minutes, close your eyes for ten seconds when you hear laughter... Every rule is a game of life and death, and there will be consequences if you violate it. In this multi-layered "fog world", he formed a temporary team with the slick programmer Zhang Xu and the chatty "humanoid navigator" Xiaopang. They shuttled through deadly replicas such as abandoned hospitals, strange streets, and bell tower ancestral halls, breaking the rules and finding a way to escape. However, the rules are not absolute, lies and truth are intertwined, and teammates' secrets hide murderous intent. Lin Ran gradually discovered that behind all this was a huge experimental field, and the truth about the "clockkeeper" might cost him an unbearable price.
The tense rules game, layers of reversal of suspense, and down-to-earth humor are intertwined into a heart-pounding survival adventure. Do you dare to step into the fog?
