Fantasy

He wants indoor plumbing. They think he’s conquering the world.
    Arthur was a genius engineer on Earth, capable of optimizing global logistics and automating entire factories. But he lacked one thing: common sense. Now, reincarnated as Arthur von Pendelton, the six-year-old son of a powerful Duke in a medieval fantasy world, he faces his greatest challenge yet: Drafts.
    Armed with the T.E.C.H. Interface (Trans-Epochal Construction Heuristic), Arthur can analyze magic like code and build modern technology from scratch. His goals are simple: Double-glazed windows, hot showers, and a toaster that doesn't burn the bread.
    But there is a problem. The people of this world don't understand engineering.
    He builds a high-pressure boiler for a bath; his father thinks it’s a “Dragon-Breath Siege Weapon.”
    He creates a hydroponic garden; the local church declares him the God of Harvest.
    He ignores a Princess's flirting to analyze the thread count of her dress; she thinks he is playing “hard to get.”
    Follow Arthur as he accidentally industrializes a kingdom, terrifies his enemies with home appliances, and remains completely oblivious to the fact that he is becoming the most powerful man in history.
    All he wanted was a warm bath.
