"What is dark magic?" Ryan began his conversation with the most basic questions.

"Destructive and evil magic is called black magic. Hermione thought for a moment and replied.

"This is the exact words written in the Defence Against the Dark Arts textbook, worthy of our Miss Jack-of-all-trades, all the textbooks can be remembered. Ryan complimented Hermione in a somewhat mocking tone. Then Masase said, "Actually, the core criterion for true identification of dark magic is evil rather than destructive, for example, a fire charm can make fire for us, but it can also create deadly and extremely destructive fires. But we can't think of the Fire Spell as evil. ”

"Yes, so I think the core criterion of black magic is evil, a kind of malice towards the object of the spell. That's why I'm against you learning this, I don't want my fellow student to turn into an evil dark wizard. Hermione replied.

"But the problem is that the definition of evil magic is that it is evil as long as it is cast with negative feelings about the desired target. It is undeniable that this kind of magic with negative emotions is often more lethal. And as the negative emotions increase, so does the power of the spell. ”

"What do you want to say?" Hermione was a little confused.

"I just feel that as long as negative emotions in certain ranges should be allowed, it doesn't mean evil. Ryan said as he flipped through the bookmarked page of the third-year dark arts textbook, pointed to one of the spells, and said, "Look, this magic needs to have an aversion to the target before it can form a force field from your wand and bounce the target away."

Disgust is a negative emotion, but I don't think it's evil. Compared to the power of these magics, this little bit of negativity shouldn't be a problem. ”

After listening to Ryan's explanation, Hermione took a textbook and flipped through it. He then said, "It is true that as one of the top three schools in the European wizarding world, there are no magicalities in the textbooks that seem too cruel, and I believe that even the professors at Hogwarts know some of these spells to a greater or lesser extent, but they are learned to ward off them." (Note 1)

I fear that our age and mind may well be led astray by power, which is why I think Hogwarts only allows older Defence Against the Dark Arts students to view certain books related to the Dark Arts in the Forbidden Book Zone. I think that in the upper grades, we will naturally be able to study relevant knowledge under the guidance of teachers, but it should also be for the purpose of defending against them. ”

"So what do you think you should do with this knowledge? I just want to learn some powerful magic to protect myself and my friends. After all, the feeling of being powerless in the face of evil like last year is really terrible. Ryan said.

"I believe that it is only through practice that we can learn the power to resist black magic, and that it is not enough to know only theoretical knowledge, we should practice some magic of self-defense. But I don't think you should study the contents of these books, because it's black magic after all. I don't think the situation is so bad that we need to do whatever it takes to increase our strength, what happened last year was just some accident.

I won't object to you reading these books, since you have decided that you want to learn how to protect yourself, you can learn how to recognize them, deal with them, and learn some magic that can ward off them by understanding these black magic. This is enough to fight against the forces of evil and protect yourself.

You know, it's not that other magic is necessarily inferior to black magic. There's no need to cross that dangerous line to learn the dark arts. I think we should read these books together to make sure that no one takes a dangerous step. Hermione thought for a long time before pursing her lips and expressing her opinion to Ryan.

Ryan was a little surprised to hear Hermione's answer, as he found that Hermione had not only not been convinced by him, but had tried to convince him. It's just that Hermione's words also had a mental impact on him, and after a period of reflection, Ryan suddenly found that there was something wrong with his thoughts.

Indeed, Ryan knows the plot, which is an advantage. But sometimes the plot also restricts thoughts. He knew that war was about to break out, so he sometimes seemed to be in a hurry to get a quick result. However, he ignored that he had a grocery store in the Ten Thousand Worlds, and he had enough time and channels to obtain powerful power, and there was no need to be so impatient to use some methods that might cause trouble to improve his strength.

As a person with a psychological age of more than 30 years old, he has not yet seen clearly as a little girl. It made him feel incredibly ashamed.

"Thank you, I almost missed it. Thank you for pointing me in the right direction, I swear I'll never learn the dark magic above. After listening to Hermione's answer, Ryan solemnly reassured.

As a sign of his determination, Ryan gave Hermione the dark arts textbooks for safekeeping. Hermione looked relieved. After that, the two of them discussed something else, and then went home for lunch.

Ryan thinks Hermione is right, that the dark arts, which can cause severe mental irreversible damage, are not worth the risk of learning. But the other magic he mastered still needed to be practiced. It's the same as swimming, no matter how solid the theoretical knowledge is, you can't master this skill without swimming in the water.

Since you want to practice, you need to find a place that the Ministry of Magic can't monitor. Ryan thought about it and felt that Plants vs. Zombies World was a good place to practice because there were more than enough targets there. What's more, it had been a long time since he left last time, and Ryan wanted to know how his house was cleaned up.

Taking advantage of the free afternoon to go to the library, Ryan went to the library to look up and copy a large number of industrial materials related to daily life to bring to Dave as a gift. After all, it was a zombie apocalyptic world, although now humanity is slowly starting to grow stronger and rebuild its homeland. However, many things are not so easy to recover, and Ryan plans to bring some materials related to daily chemistry to help the people of that world rebuild a modern civilization.

At dinner in the evening, his mother, Ms. Sally, asked Ryan, "I have a question that I haven't asked, why do I have to go to the library every morning after the summer vacation starts? ”

"Because I'm doing homework with a classmate, Mom. Ryan said as he ate the pasta on his plate.

"Classmate, dentist Granger's daughter? You seem to have said that last semester she was the first in your grade. Mr. Lambert interjected at this time.

"Uh, yes. I didn't get as high as her last semester. Ryan replied quietly.

"So when you do your homework with her, you have to learn from her strengths, and in fact we have been worried that you are a little proud because of your good grades in primary school. Mother Sally said.

After that, the two of them taught Ryan about his attitude towards learning. Ryan realized that he might have been misled by some propaganda before. Who said that European and American parents don't pay attention to their children's learning, this thing is similar all over the world.

Note: In the last book, Professor McGonagall once used the Imperius Curse to control a Death Eater, which is an unforgivable curse-level dark magic, so it is clear that at least the professors know the dark arts. It's just that the vast majority of professors learn in passing for the purpose of studying how to defend against them, with the exception of Snape's Dark Wizard professors.
