This story is about a engineer who is now the 4th prince of Graycastle in a medieval era filled with magic, Witches, Evil Churches, a Demon race and Demonic Animal beasts. This is one story where a simple enginner recreates cement, a steam engine, bicycles, guns, new medicine and... bras for women with large breasts (Yeah, I said Bras). Put some links if you want to read the Webnovel or the Webcomic.
