Modern engineer Xia Ren accidentally traveled to the Ming Dynasty. With advanced knowledge and industrialization blueprint, he started as a small official. He used assembly lines to transform workshops, used scientific ideas to innovate armaments, and used economic thinking to leverage the court. Faced with the suspicion of the imperial power, the constraints of the aristocratic family, and the obstruction of nobles, he worked step by step and turned each "impossible" into the new driving force of the Ming Dynasty. In just a few years, the Ming Dynasty transformed from an agricultural empire into a world industrial center with upgraded firearms, extensive railways, and fleet voyages. Xiaren was also promoted from a humble official to a noble, making the Ming Dynasty's industrialization process 500 years ahead of the world, ushering in a new era for China.
