"Very exciting!" Mikkel said impatiently, "I have a feeling that this year's Defense Against the Dark Arts class will be much better than in previous years. Even Lupin... Of course, I'm not saying that Professor Lupin is bad, but compared to the means of dealing with spells, those dark magic animals are indeed a bit boring."

"Oh... I really want to go and see it right away..."

Listening to his description, Cedric just felt itchy in his heart, but no, they had to wait until Friday to have the Defense Against the Dark Arts class, and now he had to go to the Herbology class outdoors.

Cedric hurried downstairs and left, and Kyle also walked into the classroom and began to organize the textbooks he would use next.

When the class started, Professor McGonagall hurried in.

Instead of starting the class directly, she spent nearly fifteen minutes emphasizing the importance of the OWL exam to the whole class.

"You must remember that this exam may affect your future for many years to come!" Professor McGonagall stood on the podium and said seriously, "But I think that as long as they invest time and energy, there is no reason why all students in this class cannot obtain the OWL certificate for Transfiguration..."

First emphasize the importance of the test, then affirm the students' abilities... well, this is very Professor McGonagall.

After fifteen minutes, she finally stopped and picked up her textbook.

"Today's class is very important. I hope that each of you can pay full attention, because we are going to learn the most difficult magic in the OWL exam, the Vanishing Spell..."

Then she demonstrated it and successfully made a snail disappear on the podium.

“Ahaha…”

Before Professor McGonagall could say anything, Mickle suddenly let out a strange laugh as if he had taken the wrong potion.

"Mr. Drake!"

Professor McGonagall said sternly, "If you find what I said ridiculous..."

"Sorry, Professor McGonagall, I'm sorry..." Mickle said quickly, but there was still a smug look on his face.

"It was in the last class. Professor Moody asked us to list the Dark Arts, and I mentioned the Vanishing Charm, but he told me that there was no such magic... Obviously he was wrong, right?"

It was the first time that Mikel surpassed a professor, a very famous professor at that, in some aspects. He was so excited that he couldn't express it in words.

Professor McGonagall was a little confused, so she walked over to Kyle, who was closest to her, and asked him what happened in the last class.

A few minutes later, she stood up again, looked at Mikel and said:

"I'm sorry, Mr. Drake, I think Alastor is right, the Vanishing Charm is indeed not considered a dark magic."

"What?" Mikel said subconsciously: "But the snail just now..."

Before he could ask, Professor McGonagall waved her wand again, and the snail that had disappeared before magically reappeared on the podium.

"First you have to understand why the Vanishing Spell belongs to Transfiguration..."

Professor McGonagall explained: "It is not like the cleansing spell that makes the object disappear directly, but it changes it into a state of nothingness. You can also understand it as an invisible ghost, or air.

But in essence, the object itself still exists, and as long as the corresponding counter-spell is cast, such as the Restoration Spell or the Recovery Spell, it can be rendered ineffective."

"Ah?" Mikel stood there blankly with his mouth open.

"Okay, sit down." Professor McGonagall waved her hand, "I won't deduct points this time, but next time I hope you can be more rigorous and understand the definition of dark magic.

Of course, you need to do this work in your free time, and don't ask me. Don't forget that it's Transfiguration time now."

Afterwards, Professor McGonagall gave each person a snail as a practice prop.

Kyle looked at the snails on the table and fell into thought.

To be honest, his attention had been focused on cross-species transformation and multiple transformations recently, and with so many things happening during the holidays, he hadn't even remembered that there was a vanishing spell in the Transfiguration spell.

Everyone started trying, and Kyle also picked up his wand and pointed it at the snail, just like Professor McGonagall had done before.

After two consecutive successes, Kyle felt that the difficulty of the Vanishing Spell was almost the same as after five transformations.

Professor McGonagall, who had been standing nearby since the students began practicing, couldn't help but nod after seeing this scene.

"Great, someone has already done it!"

She said loudly, getting everyone's attention.

"As a reward, ten points for Hufflepuff!"

There was no sound of surprise in the classroom. When everyone heard that it was Hufflepuff and saw Kyle next to her, they all lowered their heads again as if they were used to it.

Having been classmates with Kyle for five years, they have long been accustomed to this situation.

Professor McGonagall didn't say anything else. After adding the points, she prepared to go see other people.

"Professor McGonagall, I have a question!" Kyle suddenly called her.

"What?" Professor McGonagall turned around.

Kyle thought for a moment and asked, "Can the Vanishing Spell be used on oneself?"

He had been thinking about this question ever since Professor McGonagall explained the principle of the Vanishing Spell.

Making an object become nothingness, but not completely disappearing, this is the real invisibility spell.

In other words, if he used the vanishing spell on himself, he could come and go freely anywhere.

Unless the opponent uses a large-scale All Curses, the Killing Curse, the Fierce Fire Curse... or Dementors, fire dragons, will not have any effect on him.

What's more important is that this spell has no time limit. You can stay like this for as long as you want. This is simply another form of invincibility. Kyle can't help but be tempted.

"Oh?" Professor McGonagall glanced at him, her eyes twinkling.

"When I first came into contact with the Vanishing Charm, I had the same idea as you." She said, "In theory... yes, but it's difficult and far beyond your imagination. Even I can't do it now."

"You can't do it either?" Kyle frowned and asked, "Is it so difficult?"

"Because depending on the complexity of the object, the Vanishing Spell will become increasingly difficult."

Professor McGonagall said softly, "Snails and caterpillars are the easiest, but even so, most people take a long time to learn, waiting until after Christmas or even the Easter holidays before moving on to mice.

By the time you are in seventh grade, you can easily get a NEWT certificate in Transfiguration if you can make an iguana disappear.

In addition, the wizard's magic power will also have a great impact on the Vanishing Spell, especially when used on oneself. The stronger the magic power, the greater the impact.

Because our bodies will subconsciously reject this deformation, which is uncontrollable."

"So, we can't use the Vanishing Charm on ourselves anyway?" Kyle frowned.

Humans are much more complicated than iguanas. As you can imagine, to cast the vanishing spell on oneself one must have sufficient magical power as a basis.

But correspondingly, these magic powers will affect the vanishing spell, which then requires more magic power... The two seem to form an unsolvable cycle.

"No, it's still possible, I just didn't succeed." Professor McGonagall smiled, "But I really hope you can do it."
