Lin Zhiyi, a doctor of agriculture, once traveled through time and became a peasant girl in Qingpu Village of Dasheng Dynasty. Faced with the plight of her family being impoverished and her relatives being wronged, she used modern knowledge to improve rice seeds, outwit the gentry, and turn her family's fortunes around in one fell swoop. In order to have a greater voice, she resolutely chose to disguise herself as a man and embark on the road to the imperial examination. With the help of her senior fellow students from Wenrun Academy and the reform-minded Third Prince and other partners, she won three yuan in a row. After entering the official position, she started as a county magistrate at the grassroots level, built water conservancy projects, promoted agricultural technology, and made outstanding achievements. After returning to the court, she was caught in the whirlpool of the old and new party struggles. In the end, with wisdom and courage that surpassed the times, she promoted a profound agricultural revolution, realized the cleanliness of the Haiyan River, and found the love of her life.
