Ye Kai, a time traveler with the Kunlun Mirror and AI, reconstructs history with Mohist machine skills and future technology. From the Yongjia Rebellion in the Western Jin Dynasty to the Chenqiao Mutiny in the Five Dynasties, he burned the Xiongnu camp with a catapult, rewrote the battle of Feishui with a transmitter, and cracked the dynasty code with the Luban Lock. In the defiant act of destroying the Sima family and helping Zhao Kuangyin, he collided with the sparks of technology with Queen Mao, Xie Daoyun and other women - the military information was conveyed by organs and birds, and the outcome was determined by hydrological data, to explore "whether technology can splice destiny." Gulong-style short sentences outline the light of the sword, and Huang Yizhe's thoughts are asking about the way of heaven. When AI deduction encounters the torrent of history, those who go against the grain will eventually become those who take charge.
