The end of the world did not come without warning. The whole world was gloomy for three consecutive days, which was not connected by the citizens. On the fourth day, suddenly the entire city, the entire country, and the entire planet were shrouded in white smoke. At this time, both humans and animals fainted, and only the plants grew crazily again. When the white smoke recedes, everything seems to have returned to ancient times. The dead are resurrected, and animals and plants suddenly stand at the top of the food chain. Without water or electricity, the technology that people rely on for survival seems so small in the face of these powerful forces.
