The so-called "weirdness" refers to the energy materialization of extreme human emotions under specific time and space conditions. Anger, despair, resentment, and obsession—when the concentration of these emotions exceeds a critical value, they will seep into reality like nuclear wastewater, forming a "contaminated zone." Level D (mild pollution): Occasionally, supernatural phenomena occur, such as the elevator inexplicably stopping on a floor where no one is pressing the button, and the printer spitting out garbled codes (which are actually distress signals). Ordinary people can take it hard, but the Bureau of Investigation generally doesn't care. Level C (moderate pollution): Form an independent copy space, affecting 1-5 people. The rules are simple and the survival rate is about 30%. The "graduation examination room" for most novice players. Level B (severe pollution): The dungeon rules are complex and the scope of influence can reach the block level. It requires the cooperation of a professional team, and the survival rate is less than 10%. Level A (catastrophic pollution): enough to swallow up an entire city. It has only appeared three times in history, and each time it required the Bureau of Investigation to use "rule-level weapons" to eliminate them together. Class S (Theoretical Contamination): Never proven to exist. It is said that once it appears, it means that the underlying rules of the real world have been rewritten - for example, the rule "Humans must breathe" has been deleted. All the weird ones are "marginal people" abandoned by reality.
