Which novels are good, especially those about time travel and vampires?

😋I recommend the following novels to you: 1. "The True Ancestor ran off to become a vampire hunter"-The protagonist traveled to another world to become a top vampire hunter, but found himself the true ancestor of vampires, and began an exciting story. 2. "Vampire System of the Foreign Capital"-The main character Xia Lin had the Vampire System and became the peak existence of the profession of slaughtering blood ghosts, killing werewolves, and killing zombies. 3. In order to revitalize the vampire family, the protagonist was sent to the Human Academy and began a love story in the campus. I hope you like this fairy's recommendation. Muah~😗
