Simple man with his overpowered army Novel

A man discovered an immersive game through his brother, who helped him develop an overpowered character build. After his brother's death, he abandoned the game entirely, unable to face the painful memories it held. Years later, learning the game will shut down, he returns for a final farewell to this shared piece of their past. However, when the logout moment arrives, he remains trapped in his character. The NPCs begin conversing with unexpected freedom, and the capital city mysteriously relocates to a strange forest. Now stuck in this transformed world, he must navigate his new reality and discover what lies ahead. Along his journey, he encounters various individuals who take on parental roles in his life, primarily father figures, though few exemplify ideal mentorship. The story begins with a tone reminiscent of Overlord but operates on a considerably smaller scale.
