Dressed as an ancient peasant girl, her family has only four walls and three acres of farmland, which is famous for its salt-alkali land. Whatever she plants, nothing grows. Lin Sui, who just got a doctorate in agriculture: It's not a big problem, it's the right major. Others rely on timing for farming, but Lin Sui relies on science for farming. Villager A: "Ouch, the girl from the Lin family spread lime powder on the field again, can that land still be used?" - Soon after, the acidified land of the Lin family became the most fertile farmland.

She can make watermelons grow on rocky fields, cotton can grow on riverbanks, and she can also tell when it will rain and when it will be sunny, which is even more accurate than the blind fortune teller in the town! For a time, Lin Sui became the "little field god" from all over the country, and people who asked for the secret recipe for farming almost walked through the door of her house. Lin Sui carries his own "Introduction to Soil Science" and "Pest and Disease Control Manual" to hide his merit and fame. People who have studied scientific farming say it is good. However, as the fields were planted, trouble also came. The bully squire who coveted her farmland and skills, the county magistrate who wanted to take her as his concubine, and... The one who showed up at her door on time every meal time,
