Doomsday background: compound doomsday (triple disasters superimposed)
Time of the Doomsday Eruption: 2037, "The First Year of the Great Annihilation"
Three simultaneous disasters occurred around the world without any warning. The modern human civilization system completely collapsed within 72 hours, bidding farewell to the peaceful era.
1. Geological catastrophe (natural disaster): Global super plates undergo violent changes, major earthquakes of magnitude 9 or above, concentrated eruptions of super volcanoes, and tsunamis sweep across the entire coastal area. The land terrain was reshaped, a large number of cities sank into the ground and were buried in volcanic ash. Transportation, water, electricity, and infrastructure were all scrapped, and the surface was devastated.
2. Gray fog catastrophe (environmental disaster): Volcanic eruptions and underground fissures spilled massive amounts of unknown particles, forming a permanent gray fog layer around the world. Gray fog blocks the sun, the global temperature plummets, and enters a permanently cold and cloudy mode; it also pollutes the air, water, and soil, causing large-scale distortions of ordinary animals and plants, breeding extremely aggressive mutant beasts, and insect swarms, and the ecological chain is completely broken.
3. Genetic plague (man-made mutation): Gray fog particles can invade the human body and trigger gene collapse. 90% Of human beings experience three types of differentiation: those with mild symptoms continue to be weak and organ failure; those with moderate symptoms lose their minds and become bloodthirsty and violent (zombie-like); and those with severe symptoms have body distortions and transform into deformed monsters. The remaining 10% of humans are immune and can survive normally in the gray fog. They are also the core fire that continues civilization in the end of the world.
1. Absolute scarcity of resources: Food, clean water, medicine, and fuel have become hard currencies, banknotes are completely ineffective, and competition for materials is the norm in the end of the world.
2. Gray fog hazard classification: daily light gray fog can be briefly exposed, while dark gray fog and black fog areas are restricted areas
