The novel that I recommend to you is "The War Master of Transformation". It's a fantasy novel about a different continent. The main character was the Bronze-Armored Corpse, who was a doctor, and a tiger demon was guarding the house. In the story, he had to fight with his own brother, and at the same time, he got to know the cold prince and the doctor with strange ideas. Watch how the main character transforms into a master of war, defeating enemies and cultivating to become a powerhouse. I hope you like this fairy's recommendation. Muah ~😗
