Harry and Ron were also aware of this, and turned their heads to look at Ivan in disbelief, who had not been aware of his presence when they were at the observatory.

"Ivan, how exactly did you do that?" Hermione looked at Ivan and asked curiously.

"It only takes a few special spells to do it, and those Dementors are really not very smart, and it's not that hard to hide from them...."Ivan said a few vague words to fool the past, and then hurriedly changed the subject.

"That's right, Harry! You've all been at peace lately, don't go to Sirius again! Although I helped you cover up the past this time, the Aurors did not give up on finding the person who had sneaked into the observatory. ”

Harry and the others hurriedly nodded, although they had many questions, they didn't dare to ask more because of their weak hearts.

Hermione threw the books she was holding on the table with a clatter, clapped her hands, and spoke. "Now that that matter has been settled, it's time to get down to business!"

Ivan glanced at the thick books on the table, and couldn't help but be speechless,

"Collection of Trials of Major Cases in Modern Times", "Super Defense Skills - How to Crush Your Opponent in Court", "1983 English (Wizarding World) Law Amendment", "Self-cultivation of Defenders"...

"I'm just going to testify in court, so I shouldn't have to read so many books, right?" Harry looked at the thickness of the books, and inexplicably felt the urge to run.

"But do you know how to be a good witness?" Hermione glared at him, opened the book of super defense skills, crackled the pages, and pointed to the contents.

"I've seen more than 100 major cases, and I'm willing to bet that when you're in court, Peter's advocate will definitely try to make things difficult for you, he will pick out the loopholes in your words, and even use his words to lure you to the wrong conclusion."

"So you have to be ready before the trial! Even a little bit more chance of winning would be great! Hermione added.

"But who's going to find an advocate for Peter Pettigrew?" Ron pursed his lips and spouted.

But as soon as he finished speaking, he heard Hermione retort.

"Peter's mother is still alive, I found out in the memorabilia of the wizarding world that after Peter disappeared, the Ministry of Magic rewarded him with a first-class Merlin medal, which Peter's mother went to receive. And even if no one wanted to give Peter a defender, the court would find one for him! ”

Harry looked at the books piled on the table, and grimaced, he wasn't interested in reading in the first place, let alone reading these boring extracurricular books.

But in order to help Sirius, Harry had the patience to pick up one of the books and flip through it.

Ivan glanced at the thickness of the books on the table, and couldn't help but mourn for Harry for a second, thinking that he was probably busy these days...

Just as Ivan was sighing, he turned his head to see Hermione staring straight at him.

"What's wrong? Hermione! Ivan asked curiously.

"If I'm not mistaken, Ivan, you caught Peter Pettigrew, and you should be a very important witness!" Hermione shoved the book on the revision of the laws of the British wizarding world into Ivan's hand and said with certainty.

"Wait... I don't have to watch it, right? The corners of Ivan's mouth twitched, he really didn't expect Hermione to actually point the finger at him.

He had too many things to do lately, and he was really in no mood to learn the laws and regulations of the wizarding world, and Ivan didn't think that he would be stumped by the other party's defender.

"Then do you know how the Inquisition works, and how many crimes Peter has laid down?" Hermione asked.

Ivan opened his mouth to answer, but he didn't know anything about the sentencing process in the West, let alone the wizarding world.

"Okay, I'll see that!" Ivan finally sighed and resigned himself to opening the book in his hand and reading it.

He suddenly remembered that Dumbledore was not there, and Sirius's defender might have to find him himself, and it never hurt to know more about the statutes.

Hermione sat on the sidelines, intimately explaining to Ivan the legal terms related to this case, and pointed out the details that needed attention.

It's clear that the little witch has found time to read the whole book...

Seeing that Hermione was so serious, Ivan changed his previous perfunctory appearance, cheered up and began to study hard.

After learning about Ivan, he realized that the current trial process of the Ministry of Magic was quite similar to that of Muggles, but the process was much simpler in comparison.

But this is also normal, the entire British wizarding world, there are just such a few people turning over and over, there is no need to make so many curves.

In the past few days when the laws of the wizarding world have been supplemented, Ivan has not forgotten to pay attention to Peter's state, and will take the time to change into an owl to secretly visit once a day.

Peter who was imprisoned at the observatory looked very pitiful, he seemed to be tortured enough by the Dementors, and the whole person looked a little stupid, and from time to time a few whispers came out of his mouth that the Dark Lord would eventually return.

And the investigators of the Ministry of Magic also completely confirmed that Peter's memory was indeed problematic, and this appearance was not pretended.

Ivan looked at Peter with this appearance, and then remembered the other party's betrayal of his friend, and wondered if this was retribution...

After feeling for a while, Ivan did not stay here for long, and soon returned to the castle and walked towards the headmaster's office.

If he hadn't miscalculated the time, it would have been time for those people from the Merlin Order to reply to him, but I don't know if the other party would agree to his application.

"Cockroach pile!"

Ivan expertly pronounced the command to enter the headmaster's room, and the heavy guardian statue slowly turned, giving way to the entrance.

Ivan stepped into it as usual, and then his expression changed and he stopped.

There were some trivial clutter on the central office, and what he didn't expect was that Dumbledore, who had disappeared for a long time, was sitting in his chair, looking through the letters in his hand.

The phoenix Fawkes, with its golden-red feathers, rested affectionately on his shoulder, and from time to time let out a low cry like a song, as if to tell something.

"Professor Dumbledore?" Ivan asked tentatively, his experience over the past few days had left him unsure if the old professor in front of him was real.

But it should be true, because Fawkes has never been so affectionate to him...

"It's me, Hals!" Dumbledore stopped, turned his head to look at him, and nodded.
