Origin of Mutation: the Day the Sky Falls

1. Origin of mutation: The Fall Background: Three years ago, a crack appeared in the sky that shattered like glass, and the "Phase" of high-dimensional energy seeped into the real world. Practitioners: A very small number of humans whose souls resonate with the "law" awaken as "practitioners". Ability is not randomly assigned, but the embodiment of an individual's deepest obsession, subconscious or mental mechanism. Phase Erosion (Overload): Excessive or emotionally uncontrolled use of abilities will cause the soul to be assimilated by high-dimensional energy, eventually stripping away humanity and transforming into an irrational monster - an "arrhythmist".
