Peeves had a vague premonition, and when the little wizard in front of him turned his head, this ominous premonition turned into reality!

"Peeves, hasn't anyone ever told you that it's easy to get into trouble if you talk too much?" Ivan warned with a frown.

The moment he saw Ivan's face, Peeves instantly remembered his miserable appearance when they met the first few times, and suddenly let out a scream from his mouth, and Lisuo turned around and ran.

However, it was already too late, and Ivan tossed a button and raised his wand with a flick of it.

Under the influence of Transfiguration, the clasp extended into a long rope under the influence of magic, and as if it had life, it automatically wrapped around Peeves's body, binding it...

Peeves is different from other ghosts that roam the school, and although he has some ghost properties, he is a special kind of mischievous ghost, with a physical body that can pick up relatively light objects, and naturally cannot escape the ropes that Ivan has shaped.

"Hals... I don't really know anything, I don't see anything...", Peeves said in a panic as Ivan got closer and closer.

Ivan didn't believe Peeves' words, if he listened to the other party's nonsense for a while, then the news that he was going to go the next day by opening the secret passage alone would definitely spread throughout the school!

Although this does not prove that he has been in contact with Sirius, it may have an impact on his next actions, so of course Ivan can't let go of this annoying mischievous ghost so easily.

So Ivan waved his wand at Peeves, ready to give it a shot and a forgetfulness, since he was able to use the Fear Charm to affect Peeves, then the Forgetting Charm to erase memories should also work.

"Nope! Don't do that, Hals! I can promise you that I won't say anything...", looking at the magical rainbow light dancing at the top of his wand, Peeves shook his head rapidly and said with trepidation.

Perhaps Peeves' plea worked, Ivan slowly lowered his wand, touched his chin and hesitated. "Why don't you answer me a question, and I'll help you untie the rope and let you go?"

Peeves was overjoyed and nodded violently.

"You wander around the school every day, do you know where in the school there is a Boggart?" Ivan asked.

"Boggart, what are you looking for that thing for?" Peeves was very surprised, and then thought that Ivan might be trying to play tricks on someone, so he immediately became interested, so he didn't mean to hide it, and continued with a big grin.

"I saw one in Filch's filing cabinet earlier, you can look for it there..."

Ivan thought for a moment, and felt that Peeves should not be deceiving himself, after all, in the whole of Hogwarts, except for some secret passages that he didn't know, there were only a few professors and Filch's office that had not been searched.

If Peeves wants to get himself in trouble, he might as well lie to himself that Boggart is with Snape...

"Okay, I've already answered all the questions you want to ask, so don't let me go quickly." Peeves writhed uneasily and yelled, worried that Ivan would not keep his word.

"Of course, I'm a man of promise! I'll go to Filch's though, you'd better not deceive me, or I'll figure out what the consequences will be—" Ivan waved his wand and retrieved the ropes that bound Peeves, then turned them back into buttons and put them in his pocket.

"If that Boggart hadn't been disposed of, it would still be there—" Peeves chuckled as he looked happy when he was free.

But Peeves is a mischievous ghost after all, even if he promised Ivan before that he would not say anything to the outside world, but the first few times he contacted Ivan was deflated, this time he finally caught Ivan's handle, of course he would not let go of this opportunity to do things.

Peeves' blue eyes were purring, and his mind was full of all kinds of crooked ideas.

As for Ivan's follow-up revenge, it doesn't care, it's a big deal that it finds a place to hide for ten days and half a month, and when it sees Ivan in the future, it just walks around...

Just as Peeves was thinking about it and getting happier and happier, a familiar voice sounded behind it.

"Forget it!"

"Hals, you lied to me!" Peeves had only time to let out a shrill cry before he was struck by a white light, and then froze in place...

"It's not a breach of contract... I only promised to help you untie the rope and let you go, but I didn't promise anything else. Ivan put his wand away and complained to himself.

At the same time, the prompt tone of the system in my head also sounded.

【After a period of practice, your Oblivion Charm has been upgraded, and it is currently level 5 (2/1600)】

Ivan was a little surprised, unconsciously his Oblivion Charm had actually been upgraded to level five, no wonder he felt that this spell was getting more and more comfortable using recently...

After cleaning away some of Peeves' memories, Ivan pulls out the map of the living spot to look up Filch's movements.

After noticing that Filch was patrolling the other side of the castle at this time and would not return to the office for a short time, Ivan walked straight to that side, ready to make sure that Boggart was still there...

No sooner had Ivan walked out of the hallway than Peeves came back to his senses, looking around in a daze, wondering why he was here.

It's just that this doubt was quickly forgotten by Peeves, and he turned to think about which academy it would be better to toss today....

On the other side, Ivan had quietly infiltrated Filch's office.

It looked a little cluttered, with an oil lamp hanging from the dark ceiling and rows of cabinets on the walls around it.

On the right side of the room is a log desk for office use, and a small iron basin not far away, in which a messy grilled fish is abandoned, and there is a faint smell passing through.

Due to the urgency of time, Ivan walked directly to the filing cabinets, opened them one by one, and searched for them, most of which contained some parchment recording of students' disciplinary violations, as well as strange small objects that had been confiscated.

Ivan also saw a lot of familiar prank goods such as big dung eggs, fireworks, and quick-acting skipping candy in one of the cabinets with the words "confiscation of supplies, high danger", apparently George and Fred overturned the car while doing something and were caught by Filch...

Finally, when Ivan opened the cabinet on the far right, it was no longer a file bag or a prank merchandise, but a flattened human head, looking at him with open eyes...
