The soul of the mechanical scroll king Lin Che travels to the Yong Dynasty. He starts as a tenant, encounters village bullies who steal girls, and landowners bully others. He builds a trebuchet to knock out the villains, and recruits sand sculptures to follow Wang Erniu. From then on, he starts the ancient military industry! From rural simple repeating crossbows, to steam warships, steel artillery, to electric telegraphs, and internal combustion automobiles, with their mechanical skills, they protected villages, defeated the Huns, pacified Japanese pirates, expanded the Western Regions, built mechanical schools, opened blast furnaces to smelt iron, and laid tracks for trains, kicking the feudal dynasty into the industrial age! The games in the court are full of jokes, the daily life in the school is chaotic, and the stupid followers are constantly getting into trouble. Lin Zhe knows all the details, blowing up the streets with military industry all the way, and is full of pleasure. From a country craftsman to a machine king, he builds the country with scrap iron, dominates Kyushu with machinery, builds an industrial empire unique to Dayong, and makes all the countries in East Asia bow to him!
