During a famine year, agricultural academy academician Li Xiangnan is reborn back to his wedding night, only to find his younger brother about to violate his wife. Breaking his brother's arm with a single stick, he leaves the household with nothing alongside his wife, moving into a wilderness melon shed. While everyone waits to see a joke, he digs the village's first well, improves compacted soil, and grows life-saving grain. When his younger brother kidnaps his wife to extort three thousand yuan, he attends the meeting alone; when the entire commune loses water, he opens the floodgates to save ten thousand people. From a good-for-nothing to an agricultural god revered by all, he uses the knowledge of two lifetimes to protect his loved one in this lifetime and live out the most magnificent life.
