Before the emergence of Martial Artists, the think tank of the great Xia had made calculations. According to the duration of previous disasters and the current reserves of food in most of the Xia's Refuge Centers, there would be enough to sustain the existing survivors until the end of the scorching heat.

While the rise in Spirit Energy concentration benefited not only humans but also the plant and animal cultivation in the underground Refuge Centers, it could not make up for the increasing food demand of the survivors.
