After We Married, My Husband Was Possessed

Gu Yun marries the Duke of Ying's most good-for-nothing heir. She thinks that as long as she bears him a child, she can give him the title of father. As for her husband, what's the use of one? Can you eat him? But then Pei Shu is stripped of his title as heir, and the couple are driven out of the duke's estate. Gu Yun: ... She thought she'd get a domestic scheming story, but instead she gets a farming story. Pei Shu, a top scientist of national importance, transmigrates into the body of the Duke of Ying's good-for-nothing heir. He died of overwork in his previous life and thought he could finally retire and lie flat. Who knew the original owner had gambling debts? The Duke of Ying flies into a rage, strips him of his title, and kicks him and his newlywed wife out of the estate. A tiny farmstead, three little maids, and fields with no shelter from the wind on either side. Now he has to get his act together. So what if he knows nothing? He'll invent a rice transplanter and a harvesting machine that can work ten mu of land. So what if nobody respects him? He'll boost grain production, build roads and reservoirs. Reading books isn't the only way to get ahead in the world. It's just that his wife always looks at him like that. Gu Yun isn't nearly as thrilled as everyone else when she sees the rice transplanter. Instead, she asks, "It's a good machine, but how did you make it?" Pei Shu, who can't read a single character, never reads books, and has never even worked in a field: ... Pei Shu: Every day I need a hundred excuses to fool my wife, and none of them work QAQ. A straight-laced STEM guy who can never figure out what his wife is thinking & a native-born scheming woman who leads her husband around by the nose PS: The female lead is no saint. Told from her perspective. Theme: When you rely on a mountain, it crumbles. You have to rely on yourself.
