Apocalypse of poisonous fog and sand + resource monopoly + rise of power. The world view is apocalyptic and cruel - the sky is filled with poisonous sand, water sources are polluted, and human lives are insignificant - but the narrative tone is light and humorous. The protagonist uses "business thinking" to make money, win people's hearts, and establish power in the last days, and the feeling of being in control of the overall situation is overwhelming. What readers feel is "see how the protagonist turns the apocalypse into his own business empire" rather than "how miserable the apocalypse will be".
