The soul of the 21st century carried a plan for improving farm tools and was reborn in the Yao Dynasty after his death at Yanmen Pass. He disguised himself as a man and became an official under the pseudonym "Su Jin". From being the ninth-rank chief minister to the third-rank minister of the Ministry of Industry, she overcame the doubts of the court and won the emperor's trust with her solid achievements such as investigating corruption in Yangzhou, introducing new laws in Jiangnan, relieving locusts in the north, and reforming water transportation across the country.
She did not seek the glory of an official position, but only wanted "the common people to have fields and food to eat" - she set up an "agricultural tool improvement workshop" in the Ministry of Industry, rolled out curved shaft plows, modified sickles and keel waterwheels, and used bamboo pipes to lay mountain irrigation networks; during the severe drought in the southwest, she and her craftsmen rushed at night to divert mountain springs, He taught the people to dig water cellars and build terraces, saving dying crops and desperate villagers. Even after he became famous, he still lived in a simple courtyard and worked all day in official offices, workshops and fields. He promoted the "Mountain Water Conservancy Law for the Convenience of the People" throughout the country, which gradually increased Dayao's grain production and sharply reduced disasters.
Over the eight years of the Spring and Autumn Period, "Su Jin" went from an unknown official who first entered the capital to become "Su Qingtian" in the eyes of the people and "the practical minister" in the eyes of officials. She put aside her love for her children and her obsession with her previous life, and took root in the great world with her talents, knowledge and sincerity - from the water towns in the south of the Yangtze River to the barren lands of the northwest, from fighting natural and man-made disasters to promoting the reform of people's livelihood. She always remembered the oath she made when she first entered the official position and walked firmly along the path of "benefiting the country and the people", so that every inch of the land in this dynasty would produce full grain and every citizen would have a steady smile on their face.
