Shen Kuo, a doctor of engineering, accidentally traveled through Yongle for three years and became a dandy scholar in Suzhou Prefecture. When the memories of two lives collided in his mind, he brought with him modern industrial knowledge and set off a technological storm that spanned ancient and modern times in this era when Zheng He was about to set sail and the dynasty was in urgent need of innovation.
Starting from improving looms and iron smelting furnaces in Suzhou, he broke through the shackles of the imperial examination by "studying things to gain knowledge". With the help of his uncle Xia Yuanji, he joined the Ministry of Civil Affairs and injected the concepts of standardized production and hydraulic machinery into the blood of the Ming Dynasty. Yongle Emperor Zhu Di's appreciation allowed him to take charge of the Longjiang Shipyard. The streamlined treasure ships and pulley winch system reborn the Pacific fleet, and he also used sextant, distillation and other technologies to escort the ocean journey.
When Japanese pirates invaded the sea, he supervised the construction of "Sea Patrol Jiao" warships and cannons, and used industrial power to build coastal defenses; to expand the Western route, he brought back rubber and high-yielding crops, and built a port in Guli to sow the flames of Chinese technology. From the coal-iron complex to the cement post road, from the establishment of the Gewu Academy to the compilation of "Introduction to Engineering", he built an industrial system step by step. An industrial revolution that began in the Yongle period made Ming Dynasty a leader in global trade and technology, and he was the "industrial backbone" that supported it all.
