I’m the Magi-Engineering Specialist Restoring Order to a Romantasy

Synopsis

All I wanted was to live comfortably in this backward medieval romance fantasy, but— "Whoaaa! The incandescent bulb is five times brighter than a mana lamp!" "This 'air conditioner' thing — it's so much cooler than frost magic!" "And it only sips the tiniest bit of mana!!" My engineering started getting mistaken for magical engineering.
