Exiled to the Frozen North, I Choose a Disabled Husband and Open Up the Wasteland to Earn a Marquisate

[Exile + farming + comparison trope + wood-type superpower + marriage first, love later + infrastructure building + disabled war god] Lin Qinghe, a wood-type ability user at the peak of her powers in the apocalypse, transmigrates into the body of a noble marquis's daughter, convicted and exiled to the freezing frontier. At the exile's wife-selection, her reborn green-tea cousin chooses the refined deputy commandant with a bright future, hoping for a comfortable life. She leaves Lin Qinghe with Huo Jin, the notorious “Living Yama” with a reputation for brutality and two crippled legs, and waits for her to die in the snow and ice. But when Lin Qinghe sees Huo Jin's bulging muscles and the fierce, lone-wolf look in his eyes, she is thoroughly pleased: What a perfect beauty. I'll take him! The frontier is short on food? She makes high-yield mutant sweet potatoes grow in an instant and piles up mountains of provisions! Some obnoxious troublemakers pick a fight? She kicks their ribs in and goes on a rampage protecting her own! The enemy launches a surprise attack? She plants a net of mutant man-eating vines to slaughter their countless troops! While her cousin is still bickering with her husband's family over a bowl of coarse rice, Lin Qinghe has already turned the bitterly cold frontier into a paradise in the north. And the rugged soldier who was once crippled not only gets his legs back, he also fights his way to become a powerful prince of a different surname, and spoils her rotten!
