Read The Mechanical Era by MaxLostchild

Kant Icurus Maybale is the only prince on the Aceaton Continent who lacks magic in a world where kings and queens wield enormous magical power. But he does have something that no one else possesses—his recollections of his prior life as an Earth-based mechanical engineer. He dares to transfer this dream world resembling the Middle Ages into the Industrial Era and acquire unfathomable wealth and power with nothing more than knowledge, intellect, and wisdom. Along the way, strong forces will do whatever it takes to pull him down because they feel threatened by his ascent to dominance. Can he succeed in bringing about a new era by conquering the continent and even the entire planet, or will the current world order smash him?
