Modern agronomy doctor Su Wanwan transmigrated into a cast-aside wife, leaving with empty hands except for a five-year-old stepdaughter Tuanzi and a barren patch of thin land. Luckily, she obtained a portable space with half an acre of black soil and a mouth of spiritual spring. She grows vegetables and raises cubs, starting from eighty copper coins, clearing twenty mu of land, and growing a full field of greenness. The neighbor Gu Yanxing is cold-faced and taciturn, but is actually the second young master of the Zhenbei Marquis Mansion, secretly investigating cases and quietly protecting her. From autumn-harvesting freeloaders to oppression by nobles, from drought and plague to meeting the emperor at the Golden Throne Hall, Su Wanwan relies on a pair of hands and a handful of soil to farm her days into thousands of acres of fertile fields with Tuanzi. The earth does not deceive people, nor do people deceive the earth.
