I never thought it would be a catastrophe or a man-made poison experiment. Until it swept the world with an unstoppable momentum, everyone was terrified and followed suit, and the dead silence and the disgusting pungent smell of disinfectant water filled the air. The long-frozen virus, celebrating its rebirth, geometrically expanding its territory, controlling the best quality human beings, eliminating the most vulnerable impurities, so far no one can be left alone, some people kneel, some people fight, this is destined to be a protracted battle.
