A modern young man accidentally travels back to ancient times and, through a twist of fate, marries a princess. He originally intends to live a leisurely, carefree life in the countryside with his beloved wife. Little does he know that the emperor himself will come knocking at his door, turning his once peaceful life into something extraordinary! Faced with backward production methods, he puts his modern knowledge to good use, improving crop varieties, promoting greenhouse farming, developing trade, and establishing education. One remarkable invention after another emerges, gradually transforming an impoverished little village into a prosperous place. From a humble country farmer to an honored guest at the imperial court, and from someone who simply wants a peaceful life to joining hands with the emperor to transform the empire, he uses modern ingenuity to solve people's livelihood problems and lead the common people toward a better life.
