With this in mind, Ivan decided to take a long-term view and at least have a suitable plan!

Thinking about things in his head, Ivan strode into an abandoned classroom.

The classroom looked very spacious, but it looked a little cluttered, with dozens of desks and chairs placed haphazardly, and the lectern was covered with thick dust.

And before he came in, there were already people in the classroom... Perhaps because of the long wait, Harry was sitting by the window, waving his wand over and over again, practicing the incantation with words in his mouth.

Hearing the sound of the door opening, Harry turned his head in surprise.

"Ivan, you're finally here!"

"Sorry, there were some changes in the middle, so I was delayed for a while!" Ivan dragged the hemp bag and closed the door, casually explaining.

Harry didn't care, of course, but he was curious about the sack Ivan was holding, especially since it was still moving, like some restless creature.

"What's in there?" Harry asked curiously.

"Of course, you'll be given the props to practice the Divine Guardian!" Ivan patted the sack, and the Dementors inside were shaking as if they wanted to get out.

"Props? Is it a Boggart? Harry thought for a moment and guessed.

Harry, who had gone through the Defence Against the Dark Arts class, immediately thought of the Boggart he had seen last time, and it would transform into the most feared thing of the people.

Harry didn't want to admit it, but Harry knew that if he faced Boggart, there was a good chance that the other party would turn into a Dementor in front of him.

This is probably the best way to practice, after all, you can't really find a Dementor to practice fighting, right?

"Nope! It's not the Boggart, the one Professor Lupin used to teach is dead, and I won't be able to find any more Bogger anytime soon... So I just went outside and grabbed a Dementor and came over. Ivan shook his head and explained casually.

Really a Dementor?

Harry was stunned, and looked at Ivan in astonishment, but he couldn't speak for a long time, and finally he could only speak.

"Your guts... It's huge! ”

Harry looked at Ivan with admiration, many wizards avoided the evil creature of the Dementor, Ivan actually caught this terrifying creature in the sack and carried it directly, Harry was speechless!

And if he's not mistaken, the Dementors were sent by the Ministry of Magic to capture Sirius Black, so was it really okay for Ivan to tie him up like this?

At this time, Harry suddenly remembered that he had just seen a large number of Dementors flying down from the sky on the other side of the window, and suddenly realized that most of the strange movements of those monsters were related to Ivan, and asked worriedly.

"Ivan, I just saw a lot of Dementors running out of the castle, are they looking for you?"

"Shhh~ Don't forget to keep it secret! This matter has something to do with the Ministry of Magic, and if it is discovered, I will probably be in big trouble..."Ivan didn't say it explicitly, put his index finger in front of his lips, made a silent motion, and said with some weakness.

Originally, Ivan just wanted to kidnap a Dementor, but so many things happened along the way, and it would not be good if he was caught by someone from the Ministry of Magic.

Although it is the consensus of the wizarding world that wizards cannot use Animagus to transform into magical creatures, Umbridge may not be able to think of himself as the troublesome Dementor, but it is also a crime to imprison an employee of the Ministry of Magic!

Harry guessed something from Ivan's attitude, and was immediately moved.

He knew very well that Ivan was taking such a risk in order for himself to practice the Patronus Charm, so Harry hurriedly said that he would keep it a secret and would never say it!

Ivan nodded, Harry is not a big mouth like Ron, he is usually more reliable, and he shouldn't be able to leak his mouth.

The only thing to be wary of was Dumbledore's use of Dementorship on Harry.

However, after more than two years of wits and courage with Dumbledore, Ivan roughly guessed that a white wizard like Dumbledore would not abuse this kind of magic that can read through thoughts and read memories.

The first few times he had used the Soul Fetch had been because what he was doing involved the Dark Lord, or because it was too unusual for the old professor to understand.

Moreover, when Dumbledore used the Soul Capture, he mostly only used it to confirm the authenticity of the words, and did not dig deep into the memory.

So it's unlikely that Dumbledore learned about today's events through Harry...

Thinking of this, Ivan no longer bothered about whether it would be exposed, and instead snapped his fingers and spoke.

"Dobby!"

As Ivan's voice echoed through the empty classroom, a short, ugly house-elf suddenly appeared in front of the two of them.

"Mr. Hals!" Dobby blinked his bulb-sized eyes on Ivan's body for a moment, then turned to Harry's, and continued in surprise.

"Oh... And the great Harry Potter is here! ”

"Hi... Dobby! Seeing the house-elf who had pitted himself so badly again, Harry was very embarrassed to say hello.

"Is there anything you can do with Dobby, sir?" Dobby, who hadn't forgotten his duty after a brief moment of joy, turned to look at Ivan and spoke.

"I need to teach Harry a magic and don't want to be disturbed. So I need to trouble you to go into the hallway, and let us know if someone is coming, understand? Ivan explained.

Although this is an abandoned classroom, the probability of someone breaking into it is very small, but it has to be guarded against.

"Yes, sir! Dobby wouldn't let anyone bother with Mr. and Harry Potter's practice magic. Dobby patted his chest and reassured, then snapped his fingers and disappeared into the classroom.

After Dobby left, Harry couldn't help but be curious, and asked, "Isn't Dobby Malfoy's house-elf?" How could it listen to you so much? ”

"You remember when Dobby stole that dark magic item last year, right? He was punished for sabotaging Malfoy's father's plans...", Ivan briefly said that he would use his means to set Dobby free.

"I think old Malfoy must have been angry then!" Harry laughed gloating when he heard Ivan slap Lucius Malfoy with a glove in his diary.

Even if he hadn't seen it with his own eyes, Harry could imagine how angry Lucius Malfoy had been, and it really made him angry.

"Yes! Then I hired Dobby! Ivan smiled and asked suddenly. How's that, Harry? Happy? ”

"Huh?" Harry looked at Ivan suspiciously, not quite understanding what he was talking about.

Ivan's expression became more and more serious, and he said seriously. "I want you to remember this feeling, the secret of the Patronus Charm is to condense positive emotions with magic and transform them into power!"
