When Professor McGonagall stopped talking, Felix noticed that Snape's expression suddenly became strange. He tried to show a nonchalant expression and said lightly: "We must take them seriously, those dark magics..."

He loosened his hand and let the parchment slip from his fingertips.

"Those things hidden under dangerous emotions are unpredictable and changeable, always beyond everyone's expectations... If the students of Hogwarts are unprepared for this, when they need it, they will find that they are just a group of headless flies." "

When it is needed!" Moody repeated loudly, "Do you need to face it, or do you need to use it? What do you think I have been doing for the past two months?"

Snape and Moody stared at each other.

After a moment of silence, Flitwick interrupted uneasily: "I think we all agree on one thing, that is, we will never teach students the dark magic-"

Snape glanced at him.

"You're right."

"That's right," Flitwick said excitedly, as if he had received some encouragement, "but we can't let students pretend not to see that dark magic is a very large category of magic. At certain times and in certain scenarios, they have more advantages."

Professor McGonagall said impatiently, "You confused me, Filius, do you agree with Ilvermorny's suggestion?"

Felix suddenly said, "Professor Flitwick should think the same as I do-accept Ilvermorny's proposal. They have only two plans. One is to test the ability of Hogwarts' reserve warriors before the other three schools arrive."

"Not only them, but all five schools will do the same thing. Referring to previous game information, you will find that there is an option to unite the weaker side to fight against the stronger side. What's more, there are five schools now, and the number of warriors has increased to three, and the situation is more complicated and changeable. Therefore, each school wants to know its own positioning, which is more convenient for formulating strategies."

Several professors nodded, agreeing with him.

"What about Ilvermorny's second plan?"

"Of course, it is to practice the Dark Arts intensively." Felix said, "Ilvermorny is not as averse to the Dark Arts as we are, but I would like to remind you that the name of the course they teach is still Defense Against the Dark Arts, not Dark Magic!"

"This means that most of the Dark Arts on this list, their students don't know."

"You mean, Felix, we can learn which Dark Arts Ilvermorny has chosen through the competition between students?" Professor McGonagall asked. Moody's fake eyes kept moving, and it seemed that he was thinking quickly.

"That's right," Felix glanced at the parchment in his hand, "There are about fifty dark magics in it, with a wide variety and different focuses. Except for Durmstrang, it is impossible for students from other schools to master them all. The best strategy is to pick out the useful parts. Traditional schools like Beauxbatons may even refuse to use dark magic like Hogwarts."

McGonagall frowned and thought, "Among the five schools, Beauxbatons' attitude towards dark magic is indeed similar to that of Hogwarts, so there is the possibility you said. As for the remaining three... Durmstrang, needless to say, their students have at least mastered most of the dark magic on the list, and Ilvermorny will choose selectively. The only uncertain thing is Ugadu..."

"What do you think of Ugadu?"

Felix shook his head slightly, "I don't know much about it, and some information is hearsay and cannot be used as a basis."

McGonagall looked up at the other professors and made a decision. "Then, I will agree to Ilvermorny's request, Filius, Felix, Professor Moody," she looked at everyone, "Can we find alternative spells to replace some of the obscure magic effects here?"

"Of course." Flitwick said sharply, "For example, the corrosive black magic here can be replaced by a softening spell, which can soften the scales of magical animals or hard stones."

"Okay." Moody said gruffly.

"That's fine with me," Felix said, "Also, we can change our thinking - we don't have to imitate, we can also find ways to prevent it, such as 'blood tracking'. If students have the awareness of preventing tracking, they can completely avoid this danger in advance."

...

After the meeting, the professors dispersed.

Felix took Snape to Flitwick's office as a guest. Flitwick brought some biscuits and tea, and while the professors were eating and drinking, they analyzed more than half of the black magic on the list.

Among the three, Flitwick is a master of spells, knowledgeable, and the spells he mastered are not limited to black magic and other categories, while Snape simply likes it. This tendency is vaguely reflected in his speech at the meeting before. As for Felix

, he also spent time studying black magic, but the number is completely inferior to the other two.

In fact, his strategy is very similar to that of Ilvermorny - just pick the right one.

The Fiery Spell is a standard powerful black magic, but it is one of his best spells. Its power has reached a certain limit. Except for the Shield Charm, which has the hope of exceeding this level, the others are at most similar to the Fiery Spell.

The next weekend, the preparatory warriors of Hogwarts gathered in an open space between the Quidditch field and the Forbidden Forest. This is a temporary practice field. Students from the two schools will compete and practice magic here.

But this has little to do with Harry and the others.

Professor McGonagall forbade them to participate. She just gathered a dozen candidates from the sixth and seventh grades and ignored them.

"Why don't you call us!" Ron complained.

"Because we are not even reserve warriors, and we have no experience dealing with dark magic except for the little knowledge taught by Professor Moody." Hermione said loudly, also reminding the group of students around who were ready to make a move.

"Who said that," Ron muttered, "As long as you find Professor Happ's memory in classroom 7 and choose the black market, you will see a room full of dark wizards - and it will end in a chaotic fight every time."

Harry and Ron were not the only ones who were unwilling to accept it.

Neville, the Weasley twins, Susan Bones, and Eddie Emilcher all came. They hid under the shade of the trees. Because they were not old enough, they could only watch the senior students and the reserve warriors of Ilvermorny sparring, and the professors were there to guide them.

"You look like abandoned little cruppies." A long-drawn voice came from behind them.

Harry felt disgusted and turned his head to glare at Draco Malfoy. Not surprisingly, he saw that he was accompanied by two followers, Crabbe and Goyle. But there were two more people with Malfoy, they were the Greengrass sisters.

In a way, Astoria, as the younger sister, is more famous, especially when her hobby is to take a walk around the Black Lake on her giant snake mount.

Harry had never spoken to her, but Hermione had. Magically, she could barely be considered a friend of Daphne Greengrass, or an opponent? Anyway, Harry couldn't figure it out. The two of them would quarrel whenever they met, but they never really fought.

And Hermione's view of Astoria was that she was a little girl spoiled by her family, and her heart was very immature. The only advantage she had was that she had no prejudice against Muggle-born wizards.

"Granger, I want to duel with you on behalf of my sister!" Astoria pointed at Hermione and shouted.

But her arrogance was immediately suppressed by Daphne patting her head.

"What are you doing here, Malfoy?" Harry said with a straight face.

"Don't make me the same as you guys," Draco mocked, "If I wanted to see it, I would go and see it openly, instead of hiding here like a group of wronged babies..."

He stopped talking because everyone's eyes were spitting anger, and some had already drawn their wands and looked at him with ill intentions.

"Let's go," Draco Malfoy said, "Let's say hello to my friends at Ilvermorny!" He walked towards the open space with the Slytherin students in a haughty manner.

"I have a good relationship with Victor, and the Graves family has a high status in the American wizarding world..." His smug voice floated over from afar, drilling into their ears, making people's hearts itch.

The rest of the people looked at each other, and Fred suddenly said, "We also know people from Ilvermorny."

"That's right." Harry immediately agreed.

"Then..." Ron looked at everyone eagerly.

"Let's go and have a look?" Fred said tentatively.

"Good idea." George answered without hesitation.

After a moment of silence, they walked towards the practice field in an orderly manner.
