Blue Star is struck by a gray-fog disaster. Plants and animals mutate, the air becomes polluted, and supplies of medicine and essential goods are completely cut off. Order collapses. Ordinary people struggle to survive by fighting over supplies and turning on one another. The female lead leads an all-women civilian team. Relying neither on supernatural powers nor on men's protection, they use agricultural knowledge, pharmaceutical skills, engineering and construction, and disciplined management to build a safe base from scratch, achieving food self-sufficiency, in-house medicine production, safe living conditions, and collective survival for women.
