Qin Mo was a teacher in Xianyang City in the Qin Dynasty. He was modest on the surface, but in fact he was sinister. The Industrial Revolution of the Qin Dynasty entered the steampunk era, but the northern demons took the opportunity to invade. The court was corrupt and incompetent, and the army was defeated. Qin Mo accidentally obtained the 'Iron Gene System' from the future, which can analyze technology to create armor similar to Iron Man. While educating poor students in school, he secretly built a steam mecha army. When the demon army came to the city, Qin Mo led his students to pilot mechas to make a comeback, and at the same time exposed the human traitor behind the demons. From an unknown teacher to a mecha war god, he wants to use technology to crush magic and protect the people of the Qin Dynasty.
