In this seemingly peaceful city, countless strange “rules” lurk beneath the surface.
Never look in the mirror at midnight. Never press the button for the thirteenth floor in an elevator. If someone rings your doorbell three times, absolutely do not open the door...
These seemingly bizarre taboos carry terrifying consequences for anyone who breaks them: death.
Lin Mo is an ordinary office worker, but after accidentally triggering these mysterious rules, he is drawn into a terrifying game with no way back.
Every rule conceals a deadly threat, and every mission tests his survival skills and his wits.
To stay alive, he has no choice but to team up with Bai Xiaoyao, who was caught up in this as well, and face one life-or-death challenge after another.
But Lin Mo soon discovers that a far greater secret lies behind these rules.
Who is making them?
What lies at the end of the rules?
And when he tries to challenge their absolute authority, he faces not only unknown punishments, but also the price of changing the world.
Master the rules, or be mastered by them. Lin Mo’s fate is about to take an irreversible turn.
Here, follow the rules and live; break them and die. Or... transcend them?
