Weird and silent invasion: The real world seems to be the same as usual, but a dimension called "weird" is quietly overlapping with our world. This overlap is not physical, but an erosion of rules and cognition. It has no entity, but it can distort reality in the form of "rules" and create one abnormal space after another where logic breaks down.
System and screening: An unknown existence that calls itself "the system" will randomly select players from all human beings from time to time and force them to enter these strange copies of rules built by "weird" power. No one knows the purpose of the "system". Is it screening, punishment, or some kind of higher-dimensional entertainment? The chosen one cannot refuse or escape. Failure means death or "alienation" that is more terrifying than death.
Real-life impact: Despite the official attempts to cover it up, the high frequency of bizarre disappearances and deaths, as well as the fragments of words brought back by survivors, have gradually made the existence of the "Rule of Strange Tales" an urban legend and an open secret in the hearts of some people. The survivors are called "rule breakers". They are not only a source of panic in society, but also the targets of certain organizations' efforts to win over or study.
