Black Technology Empire: Starting from a Border Town

Travel through different worlds and activate the black technology system. Analyze magic, integrate technology, and create the world's first steam engine, first artillery piece, and first floating battleship. Ryan Pendragon wanted to farm in peace, but he unknowingly became a nightmare for the entire continent—— "Your Majesty, the elves have surrendered." "Your Majesty, the dwarves request an alliance." "Your Majesty, the Dragon Clan is asking you if you are short of mounts."
