There is a 60-day countdown to the global catastrophe. The geomagnetic collapse, the onset of extreme cold, the landing of the abyssal beasts, and the world order instantly return to zero. Retired blaster Gu Chen awakened to the infinite space plug-in, and carried 30,000 tons of surplus grain and millions of bullets to build a steel dragon palace deep in the subway. He hoards food with his left hand and kills beasts with his right hand. He comforts people with hot pot and resets the order with bullets. When the oxygen drops to 1% and the Star Breaker beast comes to the city, he lights a 20-ton diesel steel-making furnace and melts the doomsday into the fire of a new civilization. This is the end, but also a restart - 30,000 tons of grain surplus!
