The Natural Disaster Started and I Relied on My Brain to Lead the Whole Family to Victory

[Natural disaster + escape + difficult mode + no space and no system + high IQ female protagonist + no cp] Once Su Wantang, a master of geology, crossed over, the beginning was a hellish difficulty: floods broke dams, landslides, and plagues were rampant. There is no spiritual spring space, no systematic stocking, and no koi physique. She only has the frail body of a fifteen-year-old, a family of four who are old, weak, and disabled, and the knowledge about strata, hydrology, and climate cycles in her head. While the whole village was still waiting for the government to provide disaster relief, she had already predicted that the severe flood would be followed by a severe drought, that locusts would appear after the severe drought, and that severe winter would come two months earlier. When the refugees were killing people for half a piece of bran cake, she and her family walked ahead of everyone - finding caves, identifying water sources, hoarding herbs, weaving salt cloth, and forcibly fighting their way out in the famine years. Later someone asked: Why do you, a fisherman girl, survive to the end in hell mode? Su Wantang weighed the hatchet in his hand: I am one step faster than a natural disaster.
