Doomsday Era

Era of Calamity: Age of Germ Fog** - **Bacteria outbreak**: The ancient bacteria "Bacteria" released by melting Arctic ice combine with drug-resistant bacteria promoted by human abuse of antibiotics to form a deadly airborne pollution cloud ("bacteria fog"). The bacterial mist swallows up organic matter and releases corrosive spores. The flesh and blood of those who come into contact will fester within 72 hours, eventually turning into nutrients that nourish the bacterial blanket. The bacterial mist changes the earth's energy field and induces elemental particles (fire, water, earth, air) in the earth's veins to go wild. Element-rich areas form dangerous areas such as "Crystalized Rainforest" and "Lava Lake", but elemental crystals (such as "Pure Crystal") become the only barrier to antibacterial fog. Civilization Collapse**: The global population drops sharply to 30 million. The rich and powerful occupy the "purified dome city" (powered by elemental crystals), while the lower classes struggle in the ruins. Some people develop mutations due to long-term exposure: -*Bacteria Whisperer**: Can sense the flow of bacteria mist, but the body gradually crystallizes; -**Heart Eater**: Parasitized by the bacterial mist, he becomes a living puppet that spreads spores.
