["I'm not interested in vampire stories, yeye. Why do you keep telling their stories? Besides, there aren't many vampires left in the world, so they're probably extinct by now."
The 15-year-old Zhou Yongliang displayed an annoyed expression when his grandfather kept telling him the tales about the blood-sucking creature.
Zhou Yongliang, despite having the vampire hunter blood in his body, didn't have a slight interest to be a vampire hunter. He had the supernatural power, but he didn't care about it at all.
He kept telling his grandfather to just leave him alone and stop bothering him with the vampires' story, but his grandfather was just too stubborn to listen to his request.
