　　 Prologue
　　 "What is the experience of becoming a vampire?"
When I saw this question on Zhihu for the first time, Xiang Kun didn’t take it seriously. After all, the following Gao Zan’s answers are mostly the kind of stories that are made up at first glance. The vampire inside is not. The wealthy and handsome man is the melancholy and affectionate old prodigal son, whose essence is a romance novel.
　　 There are a few answers that seriously trace the origin of vampire legends and possible medical explanations, and they all come in the back. There are few who agree with them. Obviously, most people don’t think this issue needs to be taken seriously.
　　 The person who asked this question at the beginning probably only asked it with a ridiculous attitude.
　　 Xiangkun is also regarded as a novel. After reading a few answers, he cut to other questions.
　　 At that time, he naturally would not have thought that after not long, he would have the qualifications to answer this question.
