While chatting and complaining, Ivan and the others had already walked under the tree of the beating willow and went to the screaming shack through the secret passage underneath.

Before he entered the door, all kinds of noisy sounds came, and when Ivan pushed the door in, he was surprised to find that there were as many as one or two hundred young wizards who came to the class!

Judging by the uniforms they were wearing, most of the Gryffindor and Hufflepuff wizards arrived, as did some of the Ravenclaw and Slytherin students.

Ivan didn't have to think about it to guess that the entire castle must be mostly empty by now, no wonder Ron thought that Umbridge could find something wrong, after all, her eyes were not blind.

The sound from the door quickly attracted the attention of the little wizard, and for a while, more than a hundred pairs of eyes looked at it in unison.

Standing at the forefront are the prefects of the major academies who are responsible for maintaining order.

Hannah Abbott, Ernie McMillan, Anthony Goldes, Padma Patil, and even Slytherin's prefect Pansy Parkinson are there.

With the addition of Hermione and Ron, it can be said that all the prefects of Hogwarts have arrived except Malfoy!

Being stared at by this large group of people, Ivan was one head and two big, and he originally thought that he was here to guide a study group, at most twenty or thirty people......

Thinking of this, Ivan looked at Hermione with a strange gaze.

The little witch was also a little confused when she looked at the lively screaming shack, she had only invited some trusted friends and discussed it with the prefects.

Although Hannah Abbott had promised her that she would bring some people who wanted to learn defense, Hermione didn't expect that there would be so many so-called "some people".

"Your Excellency Hals......" Ernie McMillan in the front row greeted him for the first time and said very respectfully.

Hannah Abbott and Pansy Parkinson on the side also shouted, looking at Ivan with a mixture of flattery and awkwardness.

In fact, during the summer of this year, they were ordered by their families to follow all the instructions of Ivan Hals at school and do their best to get closer to each other.

How close and how close it can be!

At the beginning, Hannah Abbott was naturally reluctant, who was not the little princess of the family these years, not to mention that their family backgrounds were good, it was good that they didn't need to be pleased by others on weekdays, so how could they take the initiative to please others.

But when they figured out the reason, they were all dumbfounded, they couldn't believe that their parents and their family had actually taken refuge in Ivan Hals, an alumnus of the same age as them!

And this classmate, who can meet from time to time, even beat away the famous mysterious person not long ago......

The huge impact of the two news made Hannah Abbott and Pansy Parkinson feel a little ridiculous, and even suspected that their parents had hysteria or were deceived from time to time.

It's a pity that the family gave them a death order, and they must obey Ivan Hals's orders at school!

Ernie McMillan knew more than the two, because his father used the meditation basin to let him personally witness what happened that night. In the presence of hundreds of wizards, the scene of Ivan Hals slapping the mysterious man away was deeply engraved in his mind.

So when Hermione said that she was going to set up a study group and have Ivan Hals as a professor, Ernie McMillan took it upon herself and took a lot of effort to bring most of the Hufflepuff wizards over.

Ernie McMillan's respectful attitude towards Ivan made the young wizards present very curious.

However, Ivan didn't want to reveal the past, so he waved his hand and spoke. "Relax, don't be too outside, just call me by my name at school."

Hearing Ivan say this, Hannah and Pansy were relieved, they were also Hogwarts prefects, and it was too embarrassing to behave like a little henchman in front of so many people.

Ernie McMillan still looks respectful, he has seen Ivan's "true face" in his memory, so he still behaves very reservedly, and he doesn't dare to slack off at all.

"Pansy, why are you here? I didn't invite you over......" Hermione asked, recovering from her surprise and looking at Pansy Parkinson with a hostile expression.

She had never informed the Slytherin students about the study group, and she had no intention of inviting them to come.

After all, there are deep contradictions between the two colleges, and they can't trust each other.

"I don't need your invitation, Granger, and you're not in charge of teaching us!" Pansy Parkinson frowned and replied-for-tat.

The Slytherin students behind him also showed disgruntled expressions on their faces, many of them were forcibly pulled by Pansy Parkinson, and now hearing Hermione say this, they were even more eager to turn around and leave.

Hermione, however, still insisted on her opinion, thinking that Pansy and the others must have some kind of conspiracy to appear here, and nine times out of ten they wanted to find out the purpose of their party, and then tell Umbridge!

The two soon quarreled in the screaming shack, and the young wizards of Slytherin and Gryffindor drew their wands, and there was a faint confrontation.

"I'm sure everyone here has no ill will, Hermione!" Ivan interrupted Hermione's argument with Pansy with a serious remark.

"But they ......," Hermione opened her mouth to reply.

"No, but ......," Ivan interrupted Hermione's words again, and then deliberately raised his voice a few more times and continued. Don't forget, we are now facing the deterrence brought by the mysterious man, everyone should unite, there are no houses here! ”

Ivan's words made Hermione think about the Sorting Hat's warning at the beginning of the school year, and then nodded, putting away her hostility towards Pansy Parkinson.

The originally tense atmosphere in the screaming shack was also eased a little by Ivan's words.

Only Ernie McMillan and the others looked at Ivan with strange eyes, if you are not mistaken, hasn't the mysterious man been defeated by you?

Ivan didn't pay attention to the doubts that rose in the hearts of several people, but turned his head to look at the more than a hundred wizards and spoke.

"Welcome to the Defence Against the Dark Arts Association I founded!"

"Because of the rush of time, your prefect may not have mentioned to you the meaning of the existence of this association, so I will briefly repeat it - I created this association for only one purpose...... That is to take back the spellcasting rights that belong to us from the Ministry of Magic! ”
