Magic Starts the Industrial Revolution

A hard-core engineering student traveled to a different world and became the direct descendant of a rich man. I wanted to be a calm office worker, but I didn't expect that I was a loser who couldn't cultivate the magical creature "war spirit"... In this magical world where technology is locked, the knowledge in your head is the strongest golden finger. Communication systems, power networks, fusion reactors, steel fleets... Can they fight against dragons, evil spirits, and powerful magical war spirits? All answers start with farming. This novel and its characters are purely fictitious.
