"The reason why the Ministry of Magic classifies some spells as black magic is because these spells are generally very lethal, and advanced black magic such as the Killing Curse requires the caster to have a strong killing intent..."

Ivan talked for several minutes in the closed Defence Against the Dark Arts classroom, thinking about what was missing, and then he stopped.

"That's all I know... Professor! Ivan finally said.

Moody looked at Ivan with a strange expression, he asked just to find a reason to tell the students about the dark arts, but he didn't want Ivan to finish everything he had to say at once.

"Professor?" Seeing that Moody didn't respond for a long time, Ivan asked tentatively.

"Huh? You're saying a great deal! Gryffindor Plus 10 points! Moody quickly reacted to Ivan's reminder and spoke in a rough voice, then turned to look at the other students and spoke.

"As Hals said, many Dark Arts require the caster to be malicious in order to be truly powerful, which is why Hogwarts does not teach Dark Arts publicly..."

"I have seen many gifted wizards, who have become so absorbed in the power of the dark arts that they have devoted themselves to the study of the advanced dark arts, to the point that their temperaments have changed dramatically..."

"In my years as an Auror, I've captured at least two dozen of these wizards, and they're either dead or staying in Azkaban!"

Moody's words were sharp, and his scarred face sent chills down the hearts of the young wizards present.

For a moment, there was silence in the Defence Against the Dark Arts classroom, until Ivan suddenly spoke.

"Professor Moody, don't you think wizards should study dark arts?"

Ivan wondered what the legendary Auror thought of the Dark Arts.

Ever since he realized the effects of snake eyes and dark magic knowledge on his temperament during the summer vacation, he has been struggling with whether or not to continue his research.

The Slytherin students also looked at Moody nervously, they had all learned both curses to a greater or lesser extent, and some of them belonged to the category of dark magic.

"Of course we shouldn't learn those evil dark arts..."Before Moody could reply, Hermione couldn't help but speak.

However, to Hermione's surprise, Moody directly interrupted her. "Nope! Miss Granger, I don't think wizards need to completely isolate themselves from the dark arts..."

"You mean, you approve of us learning the Dark Arts?" Hermione asked in surprise, she had thought that a legendary Auror like Moody, who was as jealous as hate, would be very resistant to the dark arts.

"I mean, we have to know a little bit about the dark arts to know how to deal with them!"

Moody explained, pacing the classroom on his wooden prosthetic legs, his gaze sweeping over each student's face.

After a pause, he continued.

"I just wanted to warn you not to indulge in it, and not to try to learn dangerous magic beyond your own capabilities, preferably... It's important not to do your own research! ”

"In fact, I proposed to your Headmaster Dumbledore two days ago to let go of some of the less dangerous dark arts for the upper students to teach.

It's better to have a teacher teach you than to figure it out on your own......"

Moody's hoarse, dull tone echoed through the closed classroom, and he didn't think it was a good thing to ban the teaching of the dark arts, because the students would always have access to the dark arts.

For example, the Hogwarts Forbidden Books section is a good way to acquire knowledge of the dark arts, and every year there are some clever young wizards who are self-taught and master a lot of advanced dark arts just by reading books.

However, due to the lack of guidance, I may go astray one day...

After Moody finished speaking, the young wizards present quietly discussed.

Ivan felt that Moody's philosophy was very much to his appetite, and he had always believed that there was no need to be afraid of the dark arts, and proper research and study were necessary.

If it were to be completely banned, the headmasters of the past generations would not allow these profound dark magic books to be stored in the forbidden area.

The significance of Hogwarts' Defence Against the Dark Arts class may be to allow the professors to guide students to carefully understand the relevant knowledge of the dark arts and protect themselves from harm.

Unfortunately, due to Voldemort's curse over the past few decades, most Defence Against the Dark Arts professors have not been able to perform as well as they should.

"Alright... Stop for a moment, if you have any ideas, you can discuss them after class, or just come to me after class! Moody grabbed his cane in his right hand and slammed it on the ground to keep everyone's attention focused.

"Now, I want to ask, does anyone know what the worst forms of dark magic are?" Moody asked, looking at the group of young wizards.

"The Imperius Curse, the Heart Drill Curse, and the Killing Curse I just mentioned! According to the regulations of the Ministry of Magic, they are all unforgivable curses! If the Aurors are caught unleashing on someone, the caster will be imprisoned in Azkaban! Ivan immediately replied.

Seeing Ivan get up again without consent to answer, Moody's scarred face wrinkled, and he continued to ask angrily. "Do you know why these spells are listed as unavoidable..."

Ivan didn't wait for Moody to finish speaking this time before he hurriedly replied.

"One of the reasons why it is listed as an unforgivable curse is that there is no corresponding counter-curse, for example, once hit by the killing curse, the person who is hit by the curse will be deprived of life instantly, and this process cannot be reversed!"

"Although the Imperius Curse can be resisted by will, it is also among them because a large number of wizards controlled by the Imperius Curse in the last wizarding war caused a lot of trouble to the Ministry of Magic."

"As for the Mind Drill Spell... I think it's probably because this kind of magic that tortures people to death is so inhumane! Ivan said hesitantly, looking at Moody one last time.

"Is there anything else I haven't said? Professor? ”

"I need to remind you that I'm not giving you a lesson alone! Hals..."Moody glared at Ivan, if you're done talking, then what am I going to say?

"Okay, Professor, I'll pay attention next time." Ivan also felt a little embarrassed, but the system prompt sound that came to mind made him want to stop.

Moody didn't know what Ivan was thinking, and mistakenly thought that Ivan had recognized his mistake, so he nodded in satisfaction and added.

"You've been detailed, but there's one thing I need to correct you, Hals! The Killing Curse, while powerful, requires a strong magical power as a foundation.

If you use it on me..."

Moody looked at Ivan and hurriedly swallowed the words that had come to his mouth, and pointed his cane at Harry and Ron beside him.

"I mean, if you recite Avada's life to me, the spell will most likely not work, and at most I will probably have a little nosebleed!"
