Li Shuyang, a modern social animal, passed through the book in 1974. He became an orphan in Lijia Village and got his wife Wang Mengran. Being oppressed by Zhang Dashan and his son, he relied on modern knowledge to make money by removing rusty water and making mosquito coils. After rescuing a student who fell into the water, he joined a steel factory and became a disciple of Zheng Chuanlu, an eighth-level fitter. He was promoted from a temporary worker to a third-level fitter in 3 months. He led the villagers to develop fisheries, renovate granaries, and build primary schools, expose the conspiracy between Zhang Dashan and Bai Qingqing, punish evil and promote good. Eventually, he grew into a sixth-level fitter, received commendation and housing from the factory, and counterattacked with his family, writing a chapter of wisdom and warmth in the times.
