After a hundred years of revival of Blue Star's spiritual energy, the geomagnetic field changed dramatically, the oceans flooded back, and the continent collapsed, turning 90% of the land into a wasteland. Ancient giant beasts, mutated ferocious beasts, and alien races from outside the world have appeared one after another, and the civilization of the old era has completely collapsed. Humanity has established a federal order in the new city, and the ultimate hierarchy has been solidified - the awakened and evolved ones are at the top and control resources, while ordinary mortals are reduced to consumables at the bottom, starved of food and lifeless. Retreating means death, the only way to survive is to kill.
