Western Fantasy: What Made Them Cry, “Long Live!”?

(Western fantasy + nation-building + lord + multiple heroines + multiple races + nonhuman girls + no System + sword and sorcery) After dying from an all-nighter, Allen was reborn as the only son of a noble family. He thought he could spend this life idling away, indulging in wine and women, and enjoying himself as a happy playboy. But on his eighteenth birthday, his parents cheerfully asked him to sign an "inheritance document." The next day, they skipped town with all the money. They left him with a crumbling territory buried in debt, a pack of corrupt officials eager to treat him like an open wallet, and a knightly order that could barely afford to eat. Oh, and a raven-haired maid with an unbelievably curvy figure who strutted around in front of him every day. One of her duties was to help Allen complete the "noble coming-of-age ritual" on the day he became an adult. Well... that was one duty he was definitely interested in. But first, he had to survive and wipe out every last one of those parasites. In his previous life, Allen was a wage slave who had been manipulated by capitalists for over twenty years. This time, Allen would be the one manipulating them.
