New works are released. I hope you all like them. Your attention is the motivation for my writing. I will try my best to tell every story! When the Western envoys presented the steam engine drawings, which were regarded as miraculous tricks by the princes, Yinzhen, a modern science and engineering man who traveled through time and became the fourth prince, decided to use the industrial revolution to bring the Forbidden City into the modern era, including people and dragon chairs. He used engineering thinking to reduce dimensions and combat feudal schemes. While others were still using favors, interests and marriage to win people over, Si Age directly used productivity to crush them. He turned the industrial revolution into a weapon for seizing heirs, used the spinning jenny to bribe the Jiangnan gentry, used steam battleships to intimidate the navy, and used hot air balloons to overlook the Forbidden City.
