Wang Bin, a modern doctor, accidentally traveled through the Qingli period of the Northern Song Dynasty and became a minor official on the border of Gyeongju. With his diverse knowledge of science, engineering, medicine, and liberal arts, he used scientific thinking to innovate urban defense, medical care, and farming, and even became a close friend of Fan Zhongyan, the commander of the border defense. Faced with the doubts of the Xixia cavalry and the court, the two used technology as their blade and benevolent government as their shield to build the defense line of Dashun City, composing a hymn of wisdom and courage that spans thousands of years.
