Apocalyptic Survival: Scarlet Era

A large number of anonymous packages labeled "Scarlet Gifts" suddenly appeared around the world, containing unknown red crystals. People who come into contact with crystals will experience cell mutations within 24 hours. The initial symptoms include a sudden rise in body temperature and manic moods. Later, the body structure will be distorted and they will become irrational and extremely aggressive "aberrants". Those who are not in direct contact with the crystal will also be gradually affected by the scarlet spores spreading in the air. Those with low immunity will mutate slowly, while those with normal immunity need to regularly ingest "purifiers" (special substances extracted from official safe zones) to resist spore erosion. This disaster was called the "Scarlet Change." In just one week, the global population dropped by 60%, urban infrastructure was paralyzed, and civilized order collapsed. Humanity entered the Scarlet Era with "survival" as its core.
