Once he traveled through time, Xu Zhinian became a peasant boy who was about to starve to death in the famine years, with a bare family and a "cheap daughter-in-law" who was waiting to be fed. This daughter-in-law is delicate and frail, unable to lift her shoulders or lift her hands. She has a cold temperament, and there is a sense of nobility and majesty hidden in her eyebrows that ordinary people do not have. In order to survive, Xu Zhinian had no choice but to pick up his old trade and start his farming business on this barren land. He never thought that the potatoes he planted casually could yield three thousand kilograms per acre. The liquor he brewed unintentionally attracted the rich and powerful to spend huge sums of money. Even roasting a sweet potato could make the frosty "daughter-in-law" have red eyes. He originally wanted to live a peaceful life as a landlord, farming and raising his wife. But trouble always comes uninvited, including homeless people, bandits and corrupt officials... Everyone wants to take a piece of his flesh. Xu Zhinian had no choice but to crush these monsters one by one on the field ridge while talking and laughing. Until one day, a black armored cavalry broke through the tranquility of the small village. The female general at the head knelt down on one knee in front of him and shouted "Your Majesty". Xu Zhinian was shocked to discover that the cheap wife he had raised for a long time was actually the iron-blooded empress who was rumored to have "passed away" long ago.
