Yan Ran, a military engineer, accidentally time travels into the body of the last young master of the Yan Kingdom.
At the beginning, there is only a dead walkie-talkie, a modern knowledge system, and a broken Yan Kingdom on the verge of destruction.
From playing tricks to save lives, to growing potatoes to provide food and clothing, to building workshops, establishing education, and training new troops...
While other countries were still cutting each other with bronze swords, Yan Ran had already set up a telegraph network and used hot air balloons to detect the enemy's situation;
While politicians are still lobbying for the merger of Zonglianheng, Yan Ran has already used modern management science to reshape the bureaucracy.
While Qin Shihuang was still considering the "prefecture and county system", Yan Ran had already launched the "Five-Year Plan" and "standardized production."
