◦ The sudden "Red Fog Disaster" occurred around the world, with viruses and mutated organisms raging and civilization collapsing. Lin Chen (ordinary college student/office worker) witnessed the tragic death of his relatives and friends, fled alone, hid in an abandoned city, survived by his wisdom and ruthlessness, and witnessed the ugliness of human nature (plunder, betrayal) and the glimmer of light (brief mutual aid from strangers).
◦ Key event: Being besieged by mutant dogs, when he was about to die, he awakened the "swallowing evolution" power (which can absorb the energy of mutant creatures/superpowers to advance. It can only be absorbed weakly in the initial stage and has side effects). He counterattacked the enemy and obtained the first bucket of "evolutionary resources".
