Lord: at the Beginning, West Turned into a Useless Prince.

[Western fantasy + lord + farming + no system + racial hegemony + slow-paced development] He traveled through time and became a prince. Before he could enjoy the extravagant life of eating and drinking every day, he was kicked by his biological father to the borderland where nothing matters. My brother is a general, my sister is a Dharma god, and even my younger sister can do business to make money, but I am the only one recognized by the whole family as a waste? Just trash, trash, as long as no one cares about me, I can lie down in this broken castle until the end of the world. However... Looking at the castle that is leaking like a thatched house, the black bread is so hard that it can be used as bricks, and the monsters outside the house that may rush in to eat at any time... I'm angry! "Isn't it just farming and infrastructure construction? Do you really think that my nine-year compulsory education was for nothing?!" From then on, a prince who loved to complain was forced to embark on the path of using modern knowledge to reduce dimensions and attack other worlds. "Lord, what do you want excrement for?" "Don't ask, asking is alchemy!" "Lord, what kind of magic circle did you draw?" "Stop arguing, this is called three-dimensional geometry!" Many years later, looking at the bustling city he built with his own hands, Prince Alex just wanted to say: "I really... Just want to lie down!"
