The next day, when they arrived in Professor Mel's first Defence Against the Dark Arts classroom, Professor Mel wasn't there.

They all sat down and took out their books, quills, and parchments; When Lu Hu finally walked into the classroom, they were talking.

"Good afternoon,"

He said, "Please put all the books back in your bag." Today is a practical lesson, and all you need is a wand. ”

The whole class put the books back in their school bags, and the students were not surprised, after all, the current situation is not a stable and peaceful era, the so-called practice is not to be seen, the situation is turbulent, and the Hogwarts students, who have always been active in all corners of the wizarding world, are also quietly accumulating their own strength.

"So,"

When the professor saw that everyone was ready, he said, "Will you follow me?" ”

The class was confused, but also interested, and all stood up and walked out of the classroom with Professor Mel.

He led them down the corridor where no one was around, turning a corner.

He led them into the second hallway, where he stopped, just outside the faculty lounge.

"Please come in."

Professor Mel said, opening the door and taking a step back.

The faculty lounge is a long, out-of-twine place filled with old chairs.

"Now, like this,"

Professor Mel said, waving the class to the end of the lounge.

There was nothing there, only an old wardrobe, where the faculty kept their surplus robes.

Professor Mel walked over to the closet and took a stand, the closet suddenly swaying and slamming against the wall.

"Don't worry."

Professor Mel said calmly, as several of the students jumped back in fright.

"There's a Boggart in there."

Most people feel that there is a real need to worry.

Peter glanced at Professor Lupin, his eyes full of horror, and peeked in fear at the now wobbly doorknob.

"Boggart likes dark, enclosed spaces,"

"The closet, the space under the bed, the cupboard under the sink, and once I came across an old clock hidden in my grandfather's clock. This one moved in yesterday afternoon, and I asked the principal if the faculty could leave it alone and give my third-graders some hands-on opportunities. "So, the first question we have to ask ourselves is, what is a Boggart?" Sirius raised his hand, Gryffindor's points have been deducted a lot by a few of them recently, and they have to find a way to recover some. "It's something that morphs," he said, "and it can be presented as whatever image it thinks scares us the most." "I couldn't have said it any better," said Professor Mel, Sirius proudly, "so the Boggart sitting in the dark in the closet has not yet taken on any form." It doesn't know what scares the people outside the door. No one knows what Boggart looks like when he's alone, but when I release it, it immediately becomes the thing that each of us fears the most. "That means," Professor Mel said, deliberately ignoring Neville's slight voice of terror, "that we had a huge advantage over the Boggart before we started. Have you found that advantage, Yolanda? "Oh, because there are so many of us, it doesn't know what to become, is it?" "Not bad at all." Professor Mel said.
