His relatives laughed and called him crazy, his ex-girlfriend called him a lunatic, and greedy businessmen waited to see him go bankrupt. But Lu Chen sold his house and poured every last cent into soon-to-expire food, shuttered factories, and discarded medicine. No one knew that in ninety days, the sun would turn murderous, the power grid would collapse, and the city would run dry. A single bag of rice would be worth a life. In his previous life, he died in the acid rain. This time, he got an early start with the key to the warehouse his mother left behind and activated the Disaster Survival System. Beginning with a single cubic meter of storage, he stockpiled his way to an empire. While others fought over half a packet of instant noodles, he had a climate-controlled granary. While others knelt for a single pill, he had a complete pharmaceutical production line. The scorching sun, frozen hell, gray fog, endless night, acid rain, and waves of disease descended one after another. He set the rules: work for your rations, and looters will be killed without mercy. But when he intercepted the secret of the Ark Project, he discovered that an even deeper purge conspiracy lay behind the disasters. This time, he would not just fight to survive. He would make every lofty selector kneel before his granary.
