A hundred years ago, Blue Star experienced a sudden "major magnetic change" across the globe, and countless "different magnetic fields" that were not bound by physical laws were simultaneously created out of thin air on all continents. The alien magnetic field continues to emit invisible "spiritual power", and the lives and souls exposed to it for a long time will be distorted and dangerous creatures collectively referred to as "evil" will be born.
In order to deal with the threat of evil tides, various countries have developed localized extraordinary systems one after another, and the world has entered a hidden extraordinary era. The existence of alien magnetic fields and evil among ordinary people only remains at the level of urban legends. Officials in various countries cover up the truth under the names of "geological anomaly protection zone" and "ecological control zone".
