"I recommend" The Strongest Blood Breed Begins From The System ", a fantasy novel. The story is about the male protagonist as a little vampire who uses the survival system to continuously evolve and challenge his enemies in a fantasy world. The novel had no female lead and no emotions, focusing on fantasy adventures and growth. I hope you like this fairy's recommendation. Muah ~😗
