I recommend the novel "The Target is the Salted Fish Overlord" to you. This was a fantasy novel about swords and magic. The protagonist had the ability to build special buildings, and his goal was to be a salted fish lord. This novel also had elements of a Dungeon, and there was also a Tauren follower. Moreover, the main character was a Black Dragon that knew magic. I hope you like this fairy's recommendation. Muah ~😗
