Lin Chen, a 21st-century research scientist, transmigrates into the body of Xiao Che, the good-for-nothing Seventh Prince of the Great Jing dynasty, and binds himself to the Strongest Scientific Imperial Tutor System. Drawing on his expertise in materials science, engineering, and other fields, he forges weapons from refined steel, extracts penicillin, and invents a water-powered forging machine. After weathering court intrigue, defending the borders, and putting down rebellions, he rises from a prince cornered by despair to regent and imperial tutor, helping the crown prince usher in a golden age of technology for Great Jing.
