Lin Xiaoman, a doctor of modern agriculture, was dressed as an abandoned daughter of a marquis and was thrown back to the countryside. The best relatives are watching with eager eyes, and the neighbors of the farmers are watching with cold eyes.

When the shrewd prince disguised himself as a down-and-out businessman and knocked on her firewood door, a curtain about agricultural reform, court games and redemption in troubled times was quietly opening. Let's see her measuring thousands of miles of mountains and rivers with a pair of clay legs; turning the world upside down with a grain of rice seed.
