AD 2249 is the 100th year since the "Great Cataclysm" broke out. A hundred years ago, the earth was suddenly invaded by a "stardust rain". Along with the glowing stardust falling from the sky, there were "different-dimensional cracks" that tore the surface of the earth. Various monsters with strange shapes and terrifying combat powers sprang out from the cracks, and human civilization was on the verge of destruction. In order to survive, humans rebuilt city-states on the ruins and built thousand-foot-high "crystal energy walls" (poured with crystal energy extracted from monster cores, which can resist the impact of low-level monsters), forming a three-layered pattern of "city-state-wilderness-cracks" - the city-state is the last pure land of mankind, the wilderness is a dangerous area where monsters are entrenched, and the cracks are a constant source of monsters and the only way for humans to obtain high-level resources.
Over the past hundred years, some people in the human race have gradually awakened to "superpowers" and developed a "martial arts training" system (people with superpowers can strengthen their physical bodies through practice, and ordinary people can also break through through body training and awaken weak superpowers). Superpowers are combined with martial arts to form a "high martial arts superpower" system, giving birth to countless strong men who can slay demons and demons, and mankind can barely gain a foothold. Nowadays, the strong control the voice of the city-state, while the weak can only struggle at the bottom of the city-state, or venture into the wilderness to hunt low-level monsters to make a living. "Hunting monsters, seizing crystal cores, upgrading superpowers, and protecting the city-state" has become the survival rule for everyone in this world—it is also the core of cool points: the protagonist rises from the bottom, adds points based on the system, crushes monsters, beats peers, and reaches the top of the strong.
