Can Bao, a three-and-a-half-year-old cute baby who is the spiritual form of a thousand-year-old ginseng, was chased by a little wild boar and accidentally rolled down the hillside, being adopted by the poor peasant family of Jiang Cheng. Can Bao was born able to understand the inner voices of the land and crops, possessing the spiritual energy to stimulate all things. At that time, the Jiang family was heavily in debt, the village land was poor, the barren stone beach and white saline-alkali land were difficult to farm, and they also suffered from droughts and pest disasters, making the villagers' lives difficult. With special talents, Can Bao helped her family grow giant sweet potatoes, improved the wasteland, found a life-saving spring, and joined hands with Gu Yan Zhou, who was well-read in agricultural books, and Jiang Xiao Shu, who was skilled in calculation, to form the "Agricultural Iron Triangle".
