When your mobile phone receives an unblockable text message, when urban legends become the rules of survival that you must abide by - Chen Mo, a deliveryman who was banned by the industry for reporting a rogue webmaster, ushered in his darkest birthday. The computer has a blue screen and a blood-red countdown flashes on the screen. Three contradictory rules have become his only guide to survival in the midnight Internet cafe.
"Rule 1: Do not respond to any chat after 00:10:00."
"Rule 2: If you hear three taps on the toilet partition, be sure to respond four times."
"Rule 3: The network administrator's uniform is blue."
When the countdown reached zero, the pale-faced stranger asked him to borrow a fire; when there was a regular knocking sound on the toilet partition; when he discovered that what was clearly a red uniform hanging on the network management console - Chen Mo realized that this was not a prank, but a death game in which life was a bet.
With his keen observation and super memory sharpened by society, he struggled to survive in scenes with deadly rules: looking for a way out on a midnight bus where passengers could never arrive at the stop, solving space puzzles in an endless cycle of apartment floors, and completing the entrance examination in a death company where specific etiquette must be followed.
At the same time, Lin Ying, a calm and wise female forensic doctor, is investigating a series of bizarre death cases, all of which have experienced similar "hallucinations" during their lifetimes. When she sets her suspicious eyes on the deliveryman who repeatedly appears at the scene of the crime, the two are forced to form a dangerous alliance.
When the entire world operates according to established rules, only rules-based players can rewrite the outcome.
