Chapter 22: vampire

　　 Hermione Granger's face clearly showed an expression of disapproval.
　　 If the professor on the podium is not Rozier, she must have stood up and retorted.
　　 Of course now, her dissatisfaction can only be held in the bottom of my heart.
"A righteous wizard, no matter how terrible magic he uses, as long as he is for greater benefit, the magic he uses cannot be called'black magic'!" Professor Rozier looked serious. Said:
　　 "And a wizard with a gloomy heart, no matter how magnificent the magic he uses; but if his behavior violates the interests of the wizarding class, then it is undoubtedly ‘black magic’."
　　 Then only a rustling sound was heard, and many little wizards began to take notes.
　　 "To evaluate whether a magic belongs to ‘black magic’, it is necessary to refer to its deeds, not to itself." Professor Rozier continued:
"...For example, an evil dragon broke into Hogsmeade and was about to cause devastating damage to the village and town. A powerful wizard used a very destructive spell to kill it, no matter how extreme and destructive the spell was. How terrible it is to call it black magic..."
"... And if you are a high-sounding wizard, he never uses any extreme spells in his life. But he associates with giants, associates with fairies, and even associates with Muggles, threatening the safety of the entire wizarding world anytime and anywhere... Then he uses Any magic is undoubtedly black magic!"
　　 Professor Rozier paused and continued:
"The latter are the so-called dark wizards... those wizards who have betrayed the wizarding world, colluded with other intelligent creatures, and threatened or might even seriously undermine the interests of the wizarding world... Representatives of them, for example, fifty years ago Dumbledore, the notorious dark wizard defeated by Principal Grindelwald."
　　 Next, Professor Rozier's gaze turned to Hermione Granger again.
　　 "Of course, what Miss Granger just said was not all wrong. The definition of black magic she said was the definition of black magic fifty years ago."
"But with the change of the times, black magic and black wizards have also been redefined. Those magic that will bring great pain and torture to the caster, those magic that are extremely destructive, we now call it 'Extreme magic'; and the wizards who use them, we call them'extreme wizards'!"
　　 Professor Rozier’s voice can be said to be loud and loud.
　　Hermione nodded somewhat faintly.
　　 Then she started to brush, and quickly began to remember.
　　……
　　 After this short opening remarks, the Defense Against the Dark Arts class officially began.
　　 "Turn your textbook to page 287." Professor Rozier said without a doubt: "What we are going to learn today is—"
　　 "Vampire!"
　　 Matthew flipped through the textbook while glanced at the catalogue
　　The content about vampires is almost the last few chapters of the entire "Black Magic: Guide to Self-Defense". It seems that Professor Rozier also has the habit of giving lectures out of the usual order.
"Vampires are a kind of humanoid magical creatures, and they are also quite evil dark creatures. They are usually active at night and feed on the blood of creatures at night, but generally cannot go out during the day." Professor Rozier began her lecture. :
　　 "Under normal circumstances, vampires have the same appearance as Muggles and wizards. However, they are pale and have fangs in their mouths. They are used to bite through the throats of other creatures to blood."
　　 "The blood of living creatures is necessary for vampires. If they don't take in enough fresh blood within a certain period of time, it is very deadly for them!"
"They generally live longer than Muggles and even many wizards. For example, the famous Hungarian vampire Ms. Camilla lived 196 years old; and the American vampire Amarillo Lestoat, was born in 1776. , Didn’t die until fourteen years ago. Even when they died, their appearance was almost the same as when they were young Muggles and wizards."
"At the same time, they are also resistant to magic; some spells that are dangerous for wizards have little effect on them. If you encounter an adult vampire in the wild, only very experienced adult wizards can It will be their opponent!"
　　Professor Rozier described the characteristics of vampires very carefully.
　　 not only describes the characteristics of vampires, she also teaches students how to expel or kill a vampire.
"Vampires naturally hate the smell of garlic. This is their only flaw. Carrying garlic with them is a good way to expel vampires. But some of the weapons in Muggle legends against vampires, such as silverware, crosses, holy water, etc. It will not cause any substantial harm to them."
"At the same time, the terrible thing about vampires is not as described in some Muggle works. When they are sucked into blood, they will be assimilated. The assimilation of vampires requires a very complicated process. Hug'. But in the face of some hungry vampires, wizards or Muggles can easily die from being sucked up."
"There are many ways to kill a vampire... For example, beheading or burning its body completely. In addition, stuffing a large amount of garlic into the vampire’s mouth can also cause a lot of damage to them, even Fatal injury."
　　 During the whole class, the whole class hardly had time to look up.
　　 They are tense, and they try their best to record all what Professor Rozier said.
　　 The bell finally rang after class, and Professor Rozier finally stopped:
　　 "One paper per person, on how to identify and kill vampires, at least two feet... to be submitted next Monday."
　　 She said lightly, and then walked out of the classroom gracefully.
　　……
　　 The tight breath finally disappeared.
　　 Everyone was relieved, the Defense Against the Dark Arts class is undoubtedly the most rigorous course they have taken this week.
　　 just when Matthew was about to pack up and leave.
　　 "Matthew!" A clear voice called his name, Hermione Granger.
　　 "Hello, Hermione." Matthew smiled and looked at her.
　　Draco Malfoy was also packing up his things and leaving. He glanced at the two people talking here, and then walked out of the classroom.
　　 Matthew and Hermione can be regarded as friends since the Broken Cauldron Bar, and they exchanged a few words with each other.
　　 When there are not many students left in the classroom
　　 "Matthew." Hermione lowered her voice, "Did you feel... what did Professor Rozier imply in this class?"
　　 "Hint?" Matthew shook his head without thinking, "I don't think so."
　　 "Professor Rozier is the vice-principal of Hogwarts. If there really is something, how can she not tell us publicly?"
　　 "You think too much, Hermione!"
　　 Matthew smiled and walked out of the classroom.
