The world is not as solid as it seems. When night falls, the neon lights of the city cannot conceal the cracks in reality. The anomalies known as “Rules” are like invisible curses, distorting the laws of physics and overturning common sense. Some originate in forgotten history, others in fears buried deep in the heart. They turn familiar street corners into prisons of logic and everyday trifles into deadly puzzles.
Shen Mo, a young man with the unique ability to “perceive Rules,” is a “Boundary Watcher” who walks the line between reality and illusion. He has no extraordinary strength, only a mind capable of discerning the nature of Rules and a heart that holds fast to order amid chaos. Every dusk, he must venture into realms corroded by the Rules, searching for a way out amid paradox and despair. He does not slay monsters or demons; he only corrects distorted perceptions and pulls reality back from the brink of collapse. But as he encounters more and more Rules, a deeper secret gradually comes to light: Where do these Rules come from? And what role does he himself play in this endless process of “correction”?
