[Historical Machiavellianism × Technological Revolution × Dynastic Subversion] In the 27th year of Yongchang's Dayin Dynasty (based on the Ming Dynasty), undercurrents surged under the sound of oars and lights on the Qinhuai River. When modern strategic thinking collided with the fatal whirlpool of the nine kings seizing the heir, the moment the demoted Prince Jinling opened his eyes, the chessboard was filled with bloody murderous intent. From the Lianghuai salt administration to the Nanyang trade route, he improved the hydraulic forging hammer and shocked the government and the public. He designed salt-induced bonds to leverage the foundation of the empire. The Mohist's lost organizational map was reproduced in the coke iron-making furnace, and he reorganized the war machine with standardized parts. When the barrel of the flintlock gun was aimed at the Dragon Throne, when the enlightenment thought tore apart the noble families, how the rational time-travelers used economic warfare to drain the lifeblood of the enemy country, when the "Outline of Constitution" shook the shrine of the Imperial Ancestral Temple, the Nine Layers Palace finally realized that this massacre in the name of the Industrial Revolution had just begun. "There is no room for inefficiency in this world" - Xiao Jinghuan said when he crushed the Golden Palace.
