Lin Yi, a modern science champion, accidentally traveled back in time to the son of a poor scholar in ancient times. With his extraordinary knowledge of physics and mathematics, he started by solving farming problems in his hometown and entered the county school. In the imperial examination, he used "scientific thinking" to reduce dimensions, won three yuan in a row, and became an official in the court. In the court, he applied modern scientific thinking to water control, road construction, financial management, and military training. He repeatedly made extraordinary achievements and was promoted along the way. At the same time, he founded the Institute of Gewu to spread the flame of science and launched a fierce struggle against conservative forces. In the end, he became a highly respected minister and became the chief minister of his generation, pushing the Xia Dynasty towards a "scientific renaissance" and completing his soul transformation from a "traveler" to a "pioneering pioneer of the era".
