I went to Hogwarts after being spotted by Grindelwald

Professor McGonagall said this and returned to teaching again.

Although the other little wizards were curious, many of them looked at Sean with a little gloating in their eyes.

What do you think, being detained by the strict vice-principal is not a good thing, right?

Professor McGonagall, who returned to the podium, picked up the wand. She waved it lightly, and the podium turned into a big fat pig in front of everyone's eyes! While the fat pig was still grunting, Professor McGonagall turned the wand again.

It has returned to its original state.

This move completely made the freshmen excited, and everyone couldn't wait to experience the transformation technique.

However, they soon realized that they were still far away. After taking a lot of notes, they began to try to turn matches into needles.

"Remember, when you try to deform an object, you must imagine in your mind what the object will look like after deformation. The more detailed the better." Professor McGonagall walked between the classrooms, constantly reminding everyone of the importance of transfiguration.

Key point, "When the needle appears in your mind, connect your magic wand and focus completely on the match."

"Remember, what is the essence of transfiguration? It is transformation! Remember this word, what you want to do is to change the essence of the object? No, what you want to change is the shape and structure of the object, which lasts for a certain period of time

With the reversible transformation within, you can turn the desk into a lion. It has golden hair, a long beard, and a swinging tail. It can roar like a lion and even hunt like a lion, but it will never have a lion.

The soul of a lion."

"Students, focus your attention. I don't expect anyone to succeed in one class. I just hope you know how to always be cautious and maintain respect for the art of transformation."

Professor McGonagall kept reminding all the students with her majestic and persuasive voice.

Sean took a deep breath, and then tried hard to construct the shape of a needle in his mind. But no matter how hard he tried, the match in front of him remained unchanged.

He had tried the transformation technique on his own at home, thinking that since he was so talented, he might be able to figure out some tricks, but he had not completed any transformation.

But now, under the guidance of a top transfiguration professor, it is actually so difficult.

From this, you can imagine how difficult the transfiguration technique is.

In fact, looking at the entire Hogwarts, and even the entire wizarding world, the use of high-end transfiguration is not everywhere. Coincidentally, who are the people who can actually use transfiguration to fight?

Dumbledore, Grindelwald, Voldemort...

After a comparison, it becomes clear that the profoundness and power of the transformation technique are even higher than Sean's imagination!

He turned his thoughts back to the match in front of him, trying hard to construct the damn needle in his mind.

How to change... Sean's imagination spread.

What is a match made of? The match stem is soft wood that is soaked in a phosphoric acid solution and then attached with a layer of wax. The match head is made of flammable material, an oxidizer, and some adhesives?

What about needles? Low-carbon steel wire comes from a series of processes of grinding and drilling. It is essentially iron with low carbon content...

Doesn't that mean transforming elements? After a moment of silence, Sean smiled and said, "Are you kidding me, I'm a wizard, you talk to me about science?"

He slowly sketched the shape and shape of a needle in his mind, and then tried hard to overlap it with the match in front of him. For a moment, Sean had a strange feeling.

Under the wand, his match slowly changed its shape. It became thinner and thinner, and the rough surface was coated with a metallic luster. At the same time, the round and heavy match head became sharper bit by bit.

"Huh..." Sean breathed out.

In front of him, a needle with a sharp silver luster was lying quietly on the table.

"Very good, very good, very good." Professor McGonagall adjusted her glasses, her eyes filled with disbelief. She lowered her head and looked at the needle carefully, and even touched it.

When Professor McGonagall raised her head again, her eyes could no longer hide the admiration.

"Well done, Mr. Wallop, ten points to Ravenclaw!"

Next to him, Hermione whispered: "Sean, you are great."

Then, the girl stared at his needle unwillingly, then turned to deal with her matches.

Until the end of get out of class, most of the students did not make any changes to their matches. Hermione only made some changes to the matches: the match head became noticeably smaller and thinner.

Even so, she received a rare smile from Professor McGonagall.

"Mr. Wallop, follow me." Professor McGonagall picked up the textbook and motioned for Sean to follow.

At this moment, the freshmen who were originally gloating about his misfortune suddenly changed their tune and looked at Sean's back with envy and admiration in their eyes.

"I bet Professor McGonagall must have noticed Sean's talent at first sight." Ron said confidently.

"Don't be stupid, Ron, Sean used his own performance to win the favor of Professor McGonagall." Harry said for Sean, although he was also very envious, even a little jealous.

Sean, who was following Professor McGonagall, was completely unaware of everything behind him. He was just curious about what Professor McGonagall would say to him next.

Professor McGonagall's office is located in the corridor on the second floor of the castle. It is a small study room with an unlit fireplace, and the Quidditch pitch can be seen just outside the window.

After entering the office, Professor McGonagall took out her wand and clicked it. A hidden door appeared on the wall, and Sean could only see the gravel-paved floor inside.

She went in and rummaged for a while, then came out with a book.

Professor McGonagall put the book on the coffee table, then looked at Sean: "Mr. Wallop, sit down and talk."

"Okay, Professor." Sean sat down on the soft armchair, half of his butt resting on the chair, maintaining a good posture.

Professor McGonagall glanced at him: "Let's talk about your questions first."

Sean nodded: "Yes, Professor, I don't quite understand. After all, not every wizard is a good person."

"I understand what you mean," Professor McGonagall pushed up her glasses, "You want to say that if a wizard has evil intentions and turns the fixation into a liquid or gas, as long as the magic power is maintained for a period of time, many people will suffer from what I said.

That bad situation, right?”

"Yes, Professor."

Professor McGonagall showed a rare smile: "That would indeed be a disaster, but in fact, no one can do it at the moment."

"Why?" Sean opened his eyes wide.

"In fact, if you want to turn something into food, it is very difficult. The food will have a strange taste and is easy to detect. As for liquids and gases, it seems that there are some restrictions on the transfiguration.

As far as I know, even Professor Dumbledore, the liquid he created can only last for a few seconds."
