"Very well, I suggest the rest of the students learn from Mr. Potter as well." Dracula bowed his head lightly and complimented, "Potter is quite strong-willed and not completely controlled by my Imperius Curse."

Harry looked up at Dracula in confusion, and as Dracula stopped casting the Imperius Curse, he felt the hollowness echo of the hollow in his mind disappear.

He remembered everything that had just happened very clearly, and the position of the tail vertebrae became more and more painful.

"Healing as ever (Epliskey)." Dracula's voice rang out again.

Harry felt his broken bones heal rapidly under Professor Dracula's healing spell, first developing a slight tingling sensation, then gradually disappearing from both the itching and pain, and the tail vertebrae returning to their original shape.

He widened his eyes and stood up from the ground, then hurried to leave the dueling platform.

"Don't rush to leave, Potter." Dracula stopped Harry from stepping off the dueling ring and smiled, "Remember how you just felt, let's do it again. Hopefully, you'll be able to break free from the Imperius sooner this time."

Before Harry could react, the hollowness of the Imperius curse came back to mind.

Let's turn around......

Dracula's voice resurfaced, as if echoing in the distance.

Harry had already had an experience, and resisted Dracula's command to turn his heels as he had last felt when he had been controlled by the Imperius Curse.

"Winter!"

He fell to the floor again.

This time it was the nose that hit the ground, and the nosebleed was running down.

"I don't see any significant improvement in you." Dracula casually healed Harry's nose and said in a cold tone,

"Come again!"

……

Harry tested seven times in a row, basically improving on the previous one each time, and the time he was controlled was shortened each time.

It wasn't until Harry was able to completely break free from the Imperius Curse that Dracula finally allowed him to leave the dueling table.

After leaving the dueling table, Harry felt nothing but aches.

Even though every time he fell to the ground, Dracula would use a healing charm to heal Harry's injuries. However, whether it is muscle strain or mental exhaustion, it is not something that can be directly cured by a healing spell.

So as soon as Harry got off the dueling table, he sat down on the ground next to Ron and Hermione, grinning and rubbing his aching muscles all over his body, relaxing his long-standing brain.

One by one, the surrounding wizards gathered around Harry, asking him how he had broken free from the Imperius Curse.

"Don't rush into a discussion just yet." Dracula's voice rang out from the dueling table again, "There are three unforgivable spells, and we've only explained one."

The little wizards in the audience raised their heads in surprise and looked at Dracula.

It's just that the Imperius performance just now was too exciting. Whether it's Riddle's handsome hip-hop dance, Fred and George's spicy-eyed dance, or Harry's excellent performance in breaking free from the control of the Imperius Curse, they all attract the attention of young wizards that they have never seen before.

Now that the explanation of the Imperius Curse is over, they almost thought they were going to end class!

"There's not much time, let's pick it up." Dracula glanced at the clock hanging from the walls of the Great Hall, and then explained, "Does anyone know what the other two Unforgivable Charms are besides the Imperius Curse?" ….

Scholars such as Percy, Cedric, and Hermione in the audience raised their hands high.

Dracula is trying to pick a top student to answer the question, as he has always done.

However, just as he was about to call Gryffindor's Percy up, he suddenly saw a small wizard in Gryffindor's ranks, who was usually submissive, weakly raised his hand.

"Neville Longbottom?"

Dracula was a little surprised.

Neville Longbottom's presence as a young wizard is very low, and he basically didn't raise his hand in Defense Against the Dark Arts class.

And that's not all

, Dracula also heard that Defence Against the Dark Arts was a good course for him, as if in Snape's potions class, he would always make the potions wrong, and basically every class would have some strange accidents.

Dracula looked at Neville and noticed that his expression was a little dumbfounded, as if he was also surprised by his bold move today.

"Mr. Longbottom, tell me about it." Dracula said, "What other unforgivable curse do you know?"

"I know there's a ...... Drill the Heart Mantra." Neville's voice was soft, but clear.

Dracula gave Neville a deep look, then nodded slightly.

"That's right, Gryffindor plus five points." He said.

"The iatus Curse, also known as the Torture Curse, is a very representative form of black magic and one of the three unforgivable curses."

Given the lack of time, Dracula did not find anyone to answer the question this time, "When a curse is successfully applied to a human or living being, the curse causes intense, unbearable physical pain to the victim. If the victim is cursed for a long time, it can lead to insanity."

At this point, Dracula's brow furrowed slightly.

He vaguely saw Neville's face turn a little pale, and he didn't know why.

"The Curse of the Heart was invented in the early Middle Ages, and for a time this non-life-threatening curse was quite popular, and it was not until the beginning of the 18th century that it was completely recognized as black magic, along with the Imperius Curse and the Death Curse, which are among the three unforgivable curses."

Dracula continued, "Using any of the three unforgivable spells on fellow human beings will result in a life sentence in Azkaban without parole!"

When talking about the punishment of using the Unforgivable Curse, Dracula's voice became a little cold, which made the young wizards in the audience shudder.

"Of course, I personally think that the Heart Drill Spell is the most useless of the three Unforgivable Spells." Dracula's words suddenly changed, and his tone became relaxed, "The effect of this curse is only torture, and basically it can only come in handy during torture work."

"In my opinion, using the Diamond Heart Curse for interrogation is far less efficient than putting three drops of truth in the prisoner's mouth...... What? There are still people who don't even know what the truth elixir is? I'll ask Professor Snape after class if I'm not in charge of potions."

"The reason why I say that the Mind Drill Spell is useless is because under the influence of the Heart Drill Spell, there is a high probability that the person being interrogated will make a false confession to alleviate the pain they endure in the spell, whether or not they really have the information that the interrogator is trying to seek and extract." ….

"In addition, under the torture of the Diamond Heart Charm, the interrogator cannot reveal the information protected by secret magic such as the Unbreakable Curse and the Loyalty Charm, because what the wizards say is not voluntary under the influence of the Diamond Heart Curse."

Dracula shrugged his shoulders, the disdain on his face that showed how much he despised the spell.

"Of course, a dark wizard may choose to attack with a Drill Heart Charm in a duel, causing great pain to his opponent. As long as they maintain the curse's effect, their opponents will not be able to fight back."

"A more common use than in duel is the use of the Heart-Piercing Charm by heinous dark wizards to satisfy their desire to abuse and torture others."

"To cast this curse successfully, it's not enough to just say the incantation. The sorcerer who wields this curse must have a strong desire for the suffering of the victim and derive great pleasure from the suffering of the victim."

"Therefore, this curse is, in a sense, the most cruel and perverted of the three unforgivable curses."

"Next, I'm going to show you how a dark wizard can cast a Diamond Heart Curse."

As he spoke, Dracula suddenly curled the corners of his mouth and looked at Riddle, who was still standing on the dueling ring, with malicious intentions.

"Assistant Teacher Riddle, come and cooperate with me?"

Looking at Dracula's expression, Riddle's face instantly turned pale with fright.

"Professor Dracula, don't be impulsive!" He hurriedly dissuaded, "If it's someone else's Drilling Heart Curse, I might be able to resist it, but if it's the Drilling Heart Curse you cast, then I won't be able to bear it for a few more decades!"

"Don't be so presumptuous, Riddle." Dracula laughed teasingly, "Besides, with so many pure students here, I can't let go of the Diamond Heart Charm if I were to use the Heart Drilling Charm on an innocent person! So I might as well just show you how."

"It's not...... I'm innocent too!" Riddle laughed and argued, "It's not me who does the evil, it's the ...... You can't confuse us, that man!"

"Is there any difference?" Dracula chuckled.

Riddle's next words choked in his throat.

He could see that Dracula still had some nostalgia for the secret of the Forbidden Forest being concealed by him, and using the Imperius Curse to control Riddle to dance couldn't completely calm his emotions.

The careful-eyed Professor Dracula really lives up to his reputation!

"What the hell, Professor Dracula...... Actually, you can use other creatures to demonstrate the Heart Drill Spell." Riddle wiped the sweat from his forehead and said, "I'll call Dobby over and ask him to find a little creature that doesn't have to die."

He waved his wand and shouted softly:

"Dobby?"

Dobby, a house-elf who had been taken in by Dracula as an assistant, appeared on the dueling table with a "snap".

"It's an honor to serve you, Professor Dracula, Assistant Professor Riddle." Dobby, dressed in a delicate little gown, bowed to Dracula and Riddle.

Back a little over a month before the Christmas holidays, Dracula was a little bored with life at Hogwarts and told Dobby something——....

Dracula asks Dobby to tell Riddle to teach him a Defence Against the Dark Arts lesson. During the substitute teaching period, Riddle can reach out to Dobby for appropriate help when he needs it.

During the time that Dracula didn't come back, Dobby continued to clean Dracula's office every day, and at the same time, he gradually became familiar with Riddle.

This is also the reason why Riddle knows how to summon Dobby.

"Dobby, didn't you often go to the kitchen to help out some time ago?" Riddle asked in a low voice, "Are the rats that hide in the sewers and occasionally come up and steal the ingredients still alive?"

"Those bad rats are still alive," Dobby said angrily with wide, tennis ball-wide eyes, "these bad rats stealing the wizard's food, and they should be punished immediately!"

"But there aren't enough rat poison at Hogwarts, and the house-elf chef is just going to buy some more today, so he hasn't had time to get rid of them all yet."

"Great!" Riddle breathed a sigh of relief and looked at Dracula, "Professor Dracula, those rats in the kitchen drains are pests that steal Hogwarts food, you shouldn't be able to let go of these animals, right?"

Dracula raised his eyebrows and looked at Riddle, who tried everything he could not experience the Diamond Curse, and finally shook his head with a smile.

"In that case, let's catch a rat and bring it here." He chuckled, "It just so happens that if you use animals as a demonstration, the psychological impact on the young wizards may be a little smaller."

Dobby, a house-elf with great ability, quickly grabs a mouse from the kitchen drain and brings it in.

Because he knows Dracula very well, he uses a cleaning charm to clean the rat after catching it, so as to prevent Dracula from disliking it.

"Excuse me, Dobby." Dracula looked at the clean rat Dobby brought over and nodded in satisfaction, "It needs to be enlarged, or the little wizards in the row may not be able to see clearly."

Before Dracula could cast the spell, Riddle took the lead in using the Expansion Charm on the rat, and used the Levitation Charm to levitate it in the air so that all the young wizards could do it

Enough to see the mouse clearly.

The rat swelled up and was now bigger than a normal-sized cat.

In the expectant, puzzled, or frightened gazes of the young wizards, Dracula took two steps forward and made his way to the big mouse.

He raised his wand, pointed at the mouse, and whispered:

"Bone Piercing (io)."

In an instant, the mouse's eyes widened, and its limbs kicked wildly in all directions. It flipped and flipped as its body twitched violently, swaying from side to side.

"Squeak-"

The rat squeaked violently and screamed desperately. The gray hair all over his body trembled, and the muscles in his body twitched more and more—

"Professor, stop!" Hermione suddenly shouted loudly.

Dracula turned to look at Hermione.

Instead of Dracula in the stands, she didn't look at the rat as a demonstrator, but at Neville. ….

Dracula frowned as he saw Neville's hands clutching the corners of his clothes, his joints white, his eyes wide open, and his eyes full of fear.

"How are you, Mr. Longbottom?" He withdrew his wand, and the Mind Drill Charm stopped.

The rat fell to the ground and stopped screaming, but its limbs and body twitched from time to time.

Neville stared blankly at the rat on the stage, his face pale.

"Mr. Longbottom, if the Diamond Heart Curse has ever given you some bad memories, then I want you to face it." Dracula crouched down on the edge of the dueling ring and looked gently at Neville.

"One should not dwell on the tragic past, but should face the pain that one has experienced."

"You're a Gryffindor, Mr. Longbottom. The most important thing Gryffindor lacks is courage, and don't let those setbacks along the way of life blind you and ruin your integrity."

"Think about it when you go back, I hope you'll be different in the next class."

Dracula gave Neville a deep look, stood up, and walked over to the rat that was still twitching from time to time.

"There is no specific way to resist the Heart Drilling Mantra, but it can only rely on the superior endurance for pain and the spirit of fearlessness to resist the torture and complete the counterattack in the pain." He whispered.

"Of course, if possible, I advise you not to be struck by the Mind Dashing Charm, for there are very few people who can withstand this pain."

After explaining the knowledge of the Heart Drilling Spell, Dracula's eyes suddenly became fierce.

"Now, I'll tell you about the last of the three unforgivable spells, and the most powerful......" He raised his wand slightly, pointing at the still trembling mouse.

As if sensing impending doom, the rat struggled desperately to get up from the direction of Dracula's wand, holding back the muscles that were still weak and painful.

But the next moment, that evil spell blurted out—

"Avada Kedavra."

A dazzling green light pierced the eyes, and at the same time, there was a chaotic sound whistling, as if an invisible behemoth flew through the air—

At the same time, the rat collapsed and lay on its back on the dueling table, with no further signs of twitching.

It had no scars on its body, but it was undoubtedly dead......

Several young wizards watched in horror as they tried to hold back their screams.

Among the few young wizards who couldn't hold back their shouting, Harry was included, and a picture vaguely appeared in his eyes—

It was a blinding green light, and a beautiful woman stood in front of him, and fell to the ground after being shot by the green light, and then there was an even more dazzling green light......

"The Curse of Death, also known as the Curse of Death, has no unravel, no defensive magic that can stop it, and no one can ......survive the Curse," Dracula said.

Subsequently, he paused

After a pause, he suddenly looked at Harry, "So far, the Curse has only happened to one person."

The eyes of the audience turned to look at Harry, who stared blankly at Professor Dracula on the stage, feeling that he could understand what Neville was feeling just now.

"Concentrate and look at me!" Dracula shouted, relieving Harry of some stress, "You don't have to care how Harry Potter escaped under the Requir, and don't think you can survive the Requirement."

"You won't have any resistance to the Curse!" Dracula said coldly, "So I'm going to teach you some tricks, maybe you can have some means of survival in the face of the dark wizard's life-seeking charm."

The next moment, under the gaze of the young wizards, he suddenly turned to look at Riddle.

"Riddle, use the Requirition Charm on me!"
