In 2041 AD, a strange astronomical phenomenon "Silent Flare" covered the world and lasted for a full 72 hours. There is nothing unusual about the sun, but the physical constants of the Earth begin to pulse like a heartbeat. The region of the universe where the Earth is located happens to enter a "regular rift" in the Milky Way, a cosmic zone where physical constants fluctuate periodically. In this rift, the physical laws familiar to humans are no longer absolutely stable, but ebb and flow like tides. What's even more frightening is that the cracks are filled with a brand-new particle called "original matter". It does not interact electromagnetically with ordinary matter, but can resonate with the nervous system of living things. When cracks in the rules pass over the earth, disaster strikes: All things mutate: The original matter resonates with the earth's creatures, and most animals and plants undergo uncontrollable distortions. Their body size expands, their organs become alienated, and their aggressiveness surges, forming a "catastrophic ecosystem" covering the world. Human civilization retreated to a few surviving cities within a week. Human awakening: A small number of humans also resonated, but they did not mutate, but awakened the ability to "perceive rules". Their brains can directly perceive and weakly control the physical rules disturbed by the cracks: gravity, electromagnetism, thermodynamics, quantum states... This ability is named "Rhythm".
