Lord: The inheritance right is taken away at the beginning

Due to an accident, Roning travelled to a fantasy world where fighting spirit and magic coexisted and became the eldest grandson of Marquis Wushan. Before he had time to celebrate his good fortune, he was deprived of his right to inherit the title and even faced the risk of being expelled from the family.
Fortunately, Roning obtained a piece of territory with his keen mind. Although it was remote, with the wisdom of the Blue Star people and the game system he designed, Roning gradually got rid of the difficulties, built castles, developed the economy, expanded the army and built his own empire in the alien world.
