The world is cut into countless independent "abnormal spaces" by unknown "rules". Each space has a set of survival rules that must be strictly followed. Those who violate it will encounter incomprehensible "clearance". The rules are not fixed, and will produce strange mutations with space iteration and exploration depth. Some space rules even have contradictory "traps". The core of all abnormal spaces points to a failed "space anchoring experiment" a hundred years ago. The remaining "power of rules" from the experiment continues to erode reality, and the "rule resonance" that can sense the fluctuations of the rules and rewrite the loopholes in the rules has become the key to saving the world or accelerating destruction. Lin Shen, the former archivist of the Abnormal Events Investigation Bureau, became a resonance person of the implicit rules because of his exposure to the damaged "first generation rules document". After his sister Lin Xi was involved in an abnormal space and disappeared, he embarked on a journey through various spaces to find her and uncover the truth about the rules. The characteristic of its ability is that it can sense "rule folds" where there are contradictions in the rules, but excessive use will cause itself to be eroded by the rules, causing symptoms such as memory confusion and body transparency.
