Chapter 100: I solemnly swear that my intentions are not good.

Ivan suddenly raised his head. Harry still hadn't mentioned the name of the map. How could Ron know that this old parchment was the Marauder's Map? This sounded very suspicious.

"How did you know, Ron?" Harry looked at him in surprise and then understood and said, "Oh, Fred and George told you, didn't they?"

Ron nodded hurriedly, looking a little strange.

"Well, you two, who can explain to Ivan and me what this tattered parchment is?" said Hermione impatiently.

"Hermione, this Marauder's Map was found by Fred and George in Filch's office. It can reveal all the details of Hogwarts Castle and all its locations, including all the secret passages. It can also identify the location of every person on the school grounds." Harry looked up cautiously, glanced around, and then whispered, "As long as I have your help, I can use the invisibility cloak and join you in Hogsmeade."

"What?!" Hermione stood up in surprise.

"Don't get too excited, Hermione!" Harry hastily put her down.

"If it's really like you said, you should give this map to Professor McGonagall, Harry!" Hermione said in an anxious voice.

"No, I'm not giving it to her!" said Harry sharply. "If I do that, I'll have to explain where I got it from, and Filch will know that Fred and George took it!"

"But what about Black?" said Hermione gritting her teeth. "With this map, the professors will know if he uses any of these secret passages to get into the castle...."

"He can't enter through these passages." said Harry quickly. "Fred and George said that Filch knew most of them, and the remaining entrances and exits are also well hidden. It's impossible for Black to know them."

Hermione still said with concern, "You're taking a chance, what if he knew them?"

"Black can't go to Hogsmeade, Hermione!" said Harry stubbornly. "You told me the last time you came back that there were Dementors patrolling at night. If Black showed up, they'd find out."

"But..." Hermione bit her lip and looked worried.

"Well, Hermione, are you going to accuse me?" asked Harry, smiling.

"Oh, of course I'm not! But honestly, Harry..."

"It's almost Christmas, let me relax." Harry pulled his wand out from under his cloak and looked excited. "I'll show you the map later. If Black shows up on it, we'll be the first to find out."

Hearing his words, Ivan suddenly realized.

Would it be Sirius Black? he didn't want to say, but Peter Pettigrew was still in Ron's coat pocket.

If Harry used the Marauder's Map right now, he would find Peter's name among them.

Ivan's first intention was to stop Harry, but something immediately occurred to him. This doesn't seem like a bad idea - why should I stop him?!

He had become entangled and was unable to solve this year's problem. The main reason he couldn't hand Peter Pettigrew over to Dumbledore was because he couldn't explain, without causing doubt, how he knew Peter was an Animagus.

After all, this matter was not known to anyone.

It would be too suspicious for him to identify Scabbers as Peter Pettigrew from the start.

That was the case with Tom Riddle's diary last year, in which he unknowingly told Dumbledore that he knew he was a Horcrux. Fortunately, he returned to Hogwarts a thousand years before that, so he could always say that the Founding Four had told him about it.

Dumbledore was terrifying. In addition to being the greatest white wizard in the world today, he is also a conscientious plotter.

Ivan didn't want to reveal his own cards, and then foolishly wait to be countered.

His stubbornness did not give him much progress, so he had to be very careful this year. That was why he hadn't dared to get involved until contacting Sirius Black.

But now with the help of the Marauder's Map, this problem could be solved perfectly.

If the four of them found out that Peter Pettigrew was still alive, he could easily hand him over to Dumbledore.

After the whole truth is revealed, he'll go into the forest to find Sirius Black and things will probably turn out fine.

Stupid, why hadn't I thought of that idea before?

Ivan looked at the teachers' table and Snape along with Professor Lupin were there.

He nodded in satisfaction and reached with his right hand for the wand at his waist, his eyes fixed on Ron's pocket. He concentrated and prepared to cast 'Petrificus Totalus' just as Peter's name appeared on the map.

"I solemnly swear that my intentions are not good." Harry gently raised his wand, ready to point at the parchment.

"Wait a minute, we'd better not show it here." Ron stopped Harry hastily and said in a frantic voice, "There are too many people around us, so if he catches us..."

"It doesn't matter. Just be careful and everything will be fine. I want to see if this map is as magical as Harry said." Ivan looked at Ron with some insight.

Ron turned his head and looked at Ivan's eyes with a strange look, and quickly looked away from them and focused on the map again.

"As Ivan said, we just need to be careful and not be discovered," Harry said, tapping his wand on the parchment. "I solemnly swear that my intentions are not good."

"Oh my God!" exclaimed Hermione, covering her mouth with her hands.

Everyone's eyes were glued to the parchment, and Ivan saw the thin lines of ink begin to spread like a spider's web from the point where Harry's wand had touched them. They joined, crisscrossed, opened at every corner of the parchment; then words began to bloom at the top, big green curly words, proclaiming:

Messrs. Lunaticus, Canute, Wormtail, and Antlers Purveyors of Wizarding Aids.

Mischief Makers are proud to present to you:

THE MARAUDER'S MAP

Although he already knew it, Ivan was stunned by the transformation of the scroll.

In his previous life, he had not known how Harry's father had made such a map. Now, with his current knowledge, he speculated that its creation required, in addition to a great knowledge of the Hogwarts grounds, an extremely advanced knowledge of magical spells, Transfiguration, ancient magical literature, and other magical mechanisms.

And this theoretical knowledge is only a necessary basis for their creation. Most importantly, they need a source that provides them with a large amount of mana. That is the only way to implement such fine magic on a simple scroll, and bring it to life as was the case with the Sorting Hat.

Needless to say, the makers of the Sorting Hat, the Four Founders, had enough magical power to do such a thing.

While making the Marauder's Map does not require as much mana, it still requires a fair amount that ordinary wizards should not be able to provide.

However, remembering that James Potter, Sirius Black and Peter Pettigrew learned how to be Animagi during their school days, having such a map made by them becomes much less strange. Ivan, who had mastered how to be an Animagus, knew how much magical power it requires during the first transformation; therefore, he relied on magical potions to complete it.

What did James Potter, Sirius Black and Peter Pettigrew rely on?

Especially Peter Pettigrew, that man is not a talented wizard. But still, he completed his transformation as an Animagus, and was able to become a Rat with no problems.

Ivan initially thought that they had completed this spell by relying on a lot of potions to supplement their magical power, but now it seems that this was not the case. Simply relying on potions was not enough to make living objects like the Marauder's map.

They must have found other ways. Maybe later she could ask Sirius Black.
