The Great Jing has suffered two consecutive years of drought. Thousands of miles of land have been scorched, grain prices have soared, and warfare in Liaodong rages on. Su He, a logistics worker from a post-apocalyptic base, opens her eyes to find herself in the body of a maid sentenced to exile at the frontier and assigned as a military household's wife. While the other women choose husbands with promising prospects, Su He picks the man who makes her feel safest: Xiao Zheng, the strongest hundred-household commander in the crowd. Xiao Zheng coldly refuses, saying, "I don't need a wife." Su He looks at him, then at the grain they've been issued. "Give me the grain, and I'll go with you. You handle the fighting, and I'll make sure you have food to eat." In Xiao Zheng's eyes, women are trouble: they eat a lot and cause endless problems. He doesn't lack company, nor does he have the time to support a wife.
