The Blood Professor at Hogwarts

Chapter 264: The Patronus Charm and the Reuse of Dementors

Views:

The young wizards sat in the audience, looking forward to the next new lesson, and watched eagerly as Dracula took out a... trash can

"Professor, don't we have a class?" one of the little wizards in the audience asked, "Are you going to use a trash can for class?"

Looking at this trash can, the little wizards all felt something was wrong.

They always felt that according to Professor Dracula's previous style, no matter what he took out in the classroom, it was most likely the teaching equipment for this class.

If they were asked to use a trash can to practice how to resist Dementors... Does that mean they should fight poison with poison, using the rotting smell of the garbage in the trash can to counter the decayed smell of the Dementors

Many young wizards shuddered as they imagined that this Defense Against the Dark Arts class, which they had been looking forward to, had become hopeless...

"What are you thinking about?" Dracula put the trash can on the desk and looked at the frustrated faces of the little wizards with some amusement. "This trash can is just a container. I picked it up on the train. It's still clean, so I'm too lazy to change it."

He pointed to the trash can on the desk and lifted the lid. "The things inside are the teaching materials for this class."

As he spoke, Dracula curled the corners of his mouth and snapped his fingers lightly.

The tables and chairs below the stage, along with the little wizards sitting in their seats, were pushed to the four corners of the classroom by an invisible force, forming a circle.

Then, Dracula reached into the trash can that was cast with the Traceless Extension Charm, pulled out a Dementor, placed it in the middle of the classroom, and tied it up with a rope that emitted silver light to prevent it from running around and affecting the students.

As soon as the Dementor came out, it felt the joy in the hearts of so many young and lively wizards around it, and subconsciously opened its empty mouth under its hood, ready to suck away their happiness.

The Dementors, who had spent most of their lives on a desperate island like Azkaban, had never seen such a wealthy environment. Just taking a sip here was equivalent to completely fleecing the emotions of all the prisoners in Azkaban.

However, just as it was about to absorb the emotions, a silver hand suddenly appeared on its head and slapped it. The powerful patronus power covering the hand almost shattered the Dementor's head.

"Be honest, it's not time for you to eat yet." Dracula reminded indifferently.

The Dementors immediately quieted down.

Even though it doesn't have much intelligence, its experience in the trash can these days is simply a death for it...

From time to time, that scary man would conduct experiments with the Dementors in the trash can, using his foul Patronus Charm to test the Dementors' reactions when facing a Patronus, analyzing the Dementors' feelings when surrounded by a Patronus, and experimenting with the effect of multiple Dementors fighting against a Patronus together...

In order to test specific data, Dracula sometimes amplified the power of the Patronus Charm to a very strong level, and as a result, he accidentally killed many Dementors.

This is one of the reasons why he is happy about getting a lot of Dementors. These are all his experimental materials!

The opposite of this are the Dementors.

Since seeing their first companion being destroyed, this group of "prisoners of war" have completely become obedient. They stay in the small space of the trash can every day in fear, fearing that one day they will be chosen for experiments and then turned to ashes...

The Dementor that was pulled out today to cooperate with the young wizards in learning the Patronus Charm was originally in despair, but after it came out, it was not taken directly for experiments, but instead came to a place filled with the smell of joy.

At this time, under Dracula's punishment, this lucky Dementor stayed obediently where it was, retracted its mouthparts, and tried not to release any dark breath that would make people feel cold.

"Now let's start teaching." Dracula looked at the Dementors and nodded with satisfaction, then turned his gaze to the little wizards in the classroom.

"Everyone, look towards the middle of the classroom. This ugly thing is what we are going to talk about today. I believe that everyone has seen this strange thing once on the train on the way to Hogwarts before school starts."

"Dementors are one of the darkest and most evil creatures in the entire wizarding world. They often haunt the darkest and dirtiest places in groups, living in an environment of corruption and despair, sucking away all the peace, hope and happiness in the air around them."

"In order to save costs, the Ministry of Magic hired this creature as the guard of Azkaban Prison, believing that no prisoner could escape from the encirclement of Dementors."

At this point, Dracula sneered.

"Come to think of it, the record of no one escaping Azkaban was broken not long ago. It seems that Dementors are not as omnipotent as wizards imagined."

The young wizards glanced at Harry subconsciously.

They all knew, more or less, that one of the most evil Death Eaters in legend had escaped from prison in order to kill the Boy-Who-Lived for You-Know-Who.

"Although the Ministry of Magic treats these creatures as its own employees, and even the current Minister is willing to come to Hogwarts and beg for these free laborers," Dracula laughed sarcastically, "However, I don't think they are really as harmless as ordinary Ministry of Magic employees."

"I believe most of the students here have already experienced this. Dementors can suck away human happiness and affect people's minds. In more serious cases, they can cause fainting or even mental disorders..."

"In fact, what you experience is at most the side effects of facing the Dementors, which is not as great as the impact caused by the Dementors when they attack."

"Under the attack of Dementors, wizards often feel that the light around them is being sucked away, and they gradually fall into darkness. Courage and hope fade away, and nothingness gradually takes over their hearts. If they cannot be rescued in time, their souls will eventually be sucked away—"

"The way Dementors absorb souls is called the Dementor's Kiss. Its power and effect can be found in the Killing Curse I explained to you in the Dueling Club last semester."

While explaining about Dementors, Dracula walked to the Dementor that was staying obediently in the middle of the classroom.

"This is a rare opportunity. I can show you how Dementors perform the 'Dementor's Kiss'... As usual, we must first find a test subject who is willing to dedicate himself to our teaching career."

He snapped his fingers, summoning a rat from deep in the castle dungeon, and held it by its tail in front of the Dementor's hood.

Then Dracula pulled the hood off the Dementor's head.

It was an ugly, horrible face, with only a thin layer of crusted grey skin lying drably over the empty sockets where the eyes should have been.

A vortex that seems to be made of gas or liquid is located in the lower half of the face. The vortex is like a big mouth that is ready to devour people, and it has a kind of power that can capture people's hearts and minds.

"Come on, I've prepared a treat for you. Show everyone your 'Dementor's Kiss'!"

Dracula said excitedly as he dangled the mouse near the Dementor's "mouth".

Dementor: “?”

He eats happy emotions. How can a rat be happy? Ugly rejection!

"Oh? It seems that you are not starving yet and are still picky about food." Dracula smiled gently and said softly, "Forget it, I won't force you."

His "gentle" smile seemed to have no warmth, causing the little wizards in the classroom to shudder.

"This Dementor is useless. Let's get one that's willing to cooperate." Dracula said gently, "Anyway, there's still plenty of stock in the trash can!"

The silver rope wrapped around the Dementor to restrict its movement suddenly changed its shape, as if it had turned into a burning silver flame, burning from the position close to the Dementor's skin.

The Dementor suddenly felt a pain from the depths of his soul. The tattered and dirty cloak on his body gradually turned into ashes, revealing thin, scabbed gray skin.

Soon, the skin turned into powder, and there was nothing inside!

The Dementors struggled violently, constantly making strange "crunching" sounds like the throat before death, constantly conveying their remorse to Dracula.

However, Dracula did not intend to pay attention to it. Instead, he waved his hand, accelerating the death process of the Dementor and completely destroying its body in the center of the classroom.

"Tsk, I couldn't help it again." Dracula looked at the empty center of the classroom and shrugged helplessly, "Well... occasionally killing one or two Dementors, Andros shouldn't have too many problems, right?"

He then fished another Dementor out of the trash can.

This Dementor had long sensed the tragic death of its fellow Dementor, and almost immediately restrained its terrifying aura, flew to the center of the Defense Against the Dark Arts classroom, opened its hood and approached the mouse in Dracula's hand.

It was the same as the previous one, without eyes, only a layer of gray skin covering the empty eye sockets, and its mouth was a large shapeless hole that sucked the air in front of it with a creepy "crunching" sound.

The mouse had no chance to resist. It kicked weakly with its four legs, and the new Dementor sucked a dim spot of light out of its mouth and into the shapeless hole.

Then the mouse's eyes lost their life and its whole body drooped.

Although the little wizards could not make out the expression on the Dementor's face, they could tell from its actions that the soul of a mouse was obviously not delicious.

It covered its mouth with its dry palms and made a "grunting" sound, just like a Muggle food connoisseur tasting a large mouthful of nine-turn large intestine...

"It's a wonderful demonstration. Did you see it clearly?" Dracula smiled with satisfaction and said to the little wizards.

"Dementors are fully capable of killing wizards. Don't think that Dementors are no threat to you just because you haven't had any painful experiences and won't have a violent reaction like Potter did!"

Looking at Rat, who was thrown to the ground by Dracula with no signs of survival on his body, the originally confident little wizards nodded with satisfaction and hurriedly wrote this down in their notebooks.

"Professor, how do we deal with Dementors?" Harry raised his hand and asked impatiently.

As a young wizard who was deeply affected by Dementors, he was very worried that Dementors would suddenly appear in the next Quidditch game.

If they can learn how to deal with Dementors, then the Gryffindor team might have a chance to win this year's Quidditch Cup!

"Well, I will talk about this next." Dracula nodded slightly, "Miss Granger mentioned in her previous question that a spell is needed to resist Dementors - the Patronus Charm!"

"There is a saying in the wizarding world that Dementors cannot be killed or harmed by any magic, and only the Patronus Charm can expel them."

"But... Professor, didn't you just kill a Dementor?" a young wizard asked curiously.

"That's right, so I said that's just a saying in the magic world." Dracula smiled and nodded, "But for ordinary wizards, being able to use the Patronus Charm itself is a very difficult thing, not to mention changing the form of the Patronus Charm and adding extra lethality to this spell."

"So in a sense, this statement is not wrong."

"So how does this magic work?" Harry asked nervously as he sat in his seat.

"When the Patronus Charm is cast correctly, it summons a Patronus," Dracula said. "A Patronus is a defense against Dementors - a guardian that acts as a shield between you and the Dementors."

"The Patronus is a positive force. What it advocates is exactly what Dementors feed on - hope, happiness, the desire to live. And it cannot feel despair like a real person, so the Dementors cannot harm it."

"Miss Granger is right. This spell may be too advanced for young people like you. After all, many senior wizards have difficulty using this spell."

"But the way I use the Patronus Charm is a little different from others, maybe it can help you learn the method faster." Dracula continued, "Of course, whether you can learn it depends on your understanding. I won't let those who don't study hard slow down the progress!"

"What does the patronus look like?" a young wizard asked, "Will a god be summoned to help us drive away the Dementors? If I were to choose, I would definitely summon the beautiful Aphrodite."

As he spoke, red hearts began to appear in the little wizard's eyes.

"You'd better really want to use the Patronus to drive away the Dementors..." Dracula gave him a look of disdain. "In fact, each Patronus looks different, depending on the wizard who summoned it-"

"But! You can't summon a human-shaped patronus. Everyone's patronus is an animal! So, if you have any bad ideas, stop daydreaming."

"Oh..." It can be seen that many little wizards are not so excited anymore.

"Okay, don't think about those things, we are still in class." Dracula shook his head and laughed, "When using the Patronus Charm, you must concentrate your mind and try your best to remember something happy, so that it will be effective."

"For example, when you saw Professor Snape dressed as a woman just now, did you all laugh happily? For those students who really can't remember any happy times, they can think of Professor Snape dressed as a woman while summoning the Patronus."

"The spell is this—" Dracula raised his wand.

"Expe."
