I recommend Coiling Dragon Rebirth. It's a fantasy novel about swords and magic. The main character, Wang Sen, had borrowed a corpse and returned to life, becoming the Monolithic Sword Saint of the Coiling Dragon world, Haydson. His talent in cultivation was outstanding, and he had relied on his own hard work to become an expert. The novel also has the dragon element and the sword god element, which meets your requirements. I hope you like this fairy's recommendation. Muah ~😗
