Reluctantly, Van Lin had to magically isolate his laboratory.

This made the already crowded laboratory half the size, you know, after taking out the Ravenclaw crown, Van Lin and Dobby had already cleared most of the contents of the Room of Requirement, leaving only some valuable things.

The Room of Requirement is too crowded, carrying the accumulation of Hogwarts over the millennium as well as the garbage......

However, when Harry Mo recited the training center, Van Lin found that he had done completely useless work, like an extension of space, completely isolating the original appearance of the Room of Requirement from the training venue, as if it were two different latitudes, and his own laboratory existed in a deeper place......

It's hard to imagine what kind of magic exists on the Room of Requirement, similar to the means used by the gods to hide.

However, if you want to study it, you must tear down the castle, because Van Lin found that the training ground is connected to the castle, which is like a staircase, just a training house, the first step closest to the castle.

In fact, it took a long time for Van Lin to enter the training ground from his own laboratory, and the means was apparition, and here, it seems, is not limited by the castle......

"So, that's why you smashed me?" Harry rubbed his head, Van Lin had wanted to appear in front of him, but the landing seemed to be a little off, and then he just smashed Harry to the ground.

"It was just an accident. Van Lin said, and quickly stood up, Hermione's gentle stick Van Lin straightened up his wizarding robes, while Harry looked at the two of them with a look of resentment.

In the end, Harry rewarded himself with a cleansing technique, but it was not pleasant.

Just then, there was a soft knock on the door. Harry looked back and saw that it was Ginny, Neville, Lavender, Parvati, and Dean.

"Huh!" Dean looked at the room in amazement, "What's going on?"

So Harry began to explain.

A lot of people came, so he had to explain it all over again. It was eight o'clock, and all the cushions were full. Harry walked to the door and pulled out the key, and the tinkling sound of the key silenced everyone and looked at Harry. Hermione carefully made a mark on her "Ominous Man's Ominous" and set it aside.

"Alright," Van Lin clapped his hands, "this is where we practice, you guys should stop for a moment...... Belch...... Apparently I don't think it's bad here. ”

"It's amazing!" Fred said aloud, and everyone whispered in agreement.

"Strange," Fred frowned, "we were here once to hide from Filch, remember, George? ”

"Hey Harry, what's this?" Dean asked, pointing to the speculum and demon mirrors behind him.

"Black magic detectors. Harry walked over to them, "Basically, it reacts a little bit when a dark wizard or enemy approaches. But you can't rely on it all, because sometimes you can fool the past..."

He stared into the mirror, where some dark shadows flickered, but he couldn't tell who it was. He turned.

"Okay, let's be quiet, there will be time for everyone to visit in the future, but let's think about what to practice first, and... Uh-huh—" Van Lin said, seeing someone raise his hand. "What's wrong, Hermione?"

"I think we should pick a leader first. Hermione said.

"Van Lin is the leader!" said someone at once, and everyone looked at Hermione as if they thought she was crazy.

"yes, but we should vote!" Hermione said disapprovingly, "that way it's official, it's convincing." So... Who wants Van Rim to be our leader?"

Everyone raised their hands, including a few who had been asking questions at first, though they were reluctant.

"Uh... Ok thanks. Van Lin blushed, "So...... One thing to be sure of is that I need a couple of deputies, of course, Harry will teach everyone with me, and Hermione, in fact, I have a lot to do. Harry and Hermione, in addition to managing the work, when I am not available or busy, the two of them can help everyone learn magic instead of me, do you have any opinions?"

There was a lot of talk in the crowd, and in all fairness, both Hermione and Harry could do it.

Hermione has read a lot of magic books, has a great academic record, Harry's excellence in Defence Against the Dark Arts is also obvious to all, and he has fought many terrible enemies, and at the beginning, Van Lin also planned for Harry to teach everyone, he is not suitable for everyone, if Van Lin is not there, the two of them are undoubtedly the best candidates.

Dumbledore hadn't been in school for long, and it wasn't time to break with the Ministry of Magic, so naturally, there was no point in Vanlin staying at school.

He still had a lot to do, the Horcruxes that had been left out, the vampires still had to find a way to fight the enhanced version of Voldemort, or more simply, Voldemort was killed, although then Harry's killer weapon would be useless.

But, obviously, the problem now is that since Van Lin is the leader, and Harry and Hermione are becoming his lieutenants, taking over the management of the group, then they are all Gryffindors, and the students of the other two houses are more hesitant about this.

No matter what time it is, the monopoly of the family will be addressed, and in the end, Harry, Hermione, Michael, and Ernie will become the deputies of Van Lin, and they are all representative figures of the house, but Ernie will go......

"I think we should have a name. After identifying the leader, Hermione said cheerfully, "How about promoting unity and enthusiasm in the team?"

"How about calling it 'Against Umbridge'?" said Angelina hopefully. It seems that the Quidditch affair makes Angelina's already bad sense of Umbridge even more ......

"Or 'The Ministry of Magic is a bunch of fools?'" Fred suggested.

"I was thinking," Hermione frowned at Fred, "it should be a name that doesn't show what we're doing, so that no one else knows when we talk about it elsewhere." ”

"How's the Defense Association?" Qiu said, "and when someone calls it 'DA,' people must not know what we're talking about." ”

"Hmmm!'DA' is good. Ginny said, "But the full name could be changed to 'Dumbledore's Army,' because he's the most feared person in the Ministry of Magic, right?"

There was a muttering of approval. And laughter.

"All agree with 'DA'?" Hermione said solemnly, then knelt down on the cushion and counted the votes. "Passed by a majority!"

She pinned the parchment with her name to the wall and wrote in large letters: Dumbledore's army!
