Ivan raised his head abruptly. Harry hadn't introduced it yet. How could Ron know that this old parchment was a Marauder's Map? This is really abnormal.
"How did you know, Ron?" Harry also looked very surprised, and then suddenly said, "Fred and George must have told you, right?!"
Ron nodded hastily, looking a little weird.
"Okay, you two, who can explain to Ivan and me what this tattered parchment is?" Hermione said impatiently.
"Hermione, this Marauder's Map was found by Fred and George from Filch's office. It can mark all the details of Hogwarts castle and various venues, including every secret passage and the places that appear on it. Everyone's name." Harry raised his head and looked around cautiously before lowering his voice and whispering, "With its help, I can put on the invisibility cloak and avoid other people to go to Hogsmeade with you go."
"What?!" Hermione stood up in surprise.
"Don't get excited, Hermione!" Harry hurriedly pushed her down.
"If it's what you say, you should give this map to Professor McGonagall, Harry!" said Hermione in an anxious voice.
"No, I won't hand it in!" said Harry hastily. "If I did, I'd have to say where I got it, and Filch would know it was Fred and George!"
"But what about Black?!" Hermione gritted her teeth. "He can use a passage on this map to enter the castle. The teachers will know..."
"It's impossible for him to come in through these passages." Harry said quickly, "Fred and George said that Filch knew most of the secret passages, and the entrances and exits of the remaining few secret passages are also very hidden. It is impossible for Black to come in." Know."
"You are taking a risk, what if he knows?!"
"Black can't be running around in Hogsmeade, Hermione!" Harry said stubbornly, "You told me when you came back last time that there are dementors patrolling there at night, and if Black appears, they will found him."
"But..." Hermione bit her lip, looking worried.
"Okay, Hermione, are you going to denounce me?" Harry asked with a smile.
"Oh, of course not! But honestly, Harry..."
"Christmas is coming soon, let me relax." Harry took out his wand from under the cloak and said with a relaxed expression, "Next, I will show you this map. If Black Appear on the top, we will find him the first time."
Hearing his words, Ivan woke up suddenly!
He didn't dare to say if he could see Sirius Black, but Peter Pettigrew was still in Ron's coat pocket. If Harry used the Marauder's Map at this time, he would definitely find Peter's name among the four of them .
Aiwen's first reaction was to stop, but then he realized that this didn't seem to be a bad thing. Why did he stop Harry? !
He had been struggling with this year's incident before, and the main reason why he couldn't hand Peter Pettigrew to Dumbledore was that he couldn't explain clearly without arousing suspicion, why did he know that Peter was an Animagus? !
After all, this matter is not known to outsiders.
It would be too suspicious if he recognized Scabbers as Peter Pettigrew from the start.
Last year's Tom Riddle's diary was like this. He actually told Dumbledore unknowingly that he knew it was a Horcrux. Fortunately, he went back to Hogwarts before that, and the Big Four told him You can evade your own statement.
Dumbledore is too terrifying. Although he is the greatest white wizard in the world today, he is also a complete conspiracy.
Aiwen didn't want his hole cards to be known by the opponent, and then waited foolishly to be calculated.
His Occlumency has not made much progress, so he must be extra careful this year, which is the main reason why he has not dared to do it before getting in touch with Sirius Black.
But now with the help of the Marauder's Map, this problem can be solved perfectly.
The four of them jointly discovered that Pettigrew Peter was still alive, and then he could openly capture Peter and take him to see Dumbledore.
After all the truth is revealed, go to the Forbidden Forest to look for Sirius Black, and there will be no accidents at all.
How stupid, why didn't I think of this idea before? !
Ivan glanced at the teachers' bench, where both Snape and Professor Lupine were there.
He nodded in satisfaction, put his right hand on the wand at his waist, locked his eyes tightly on Ron's jacket pocket, and concentrated secretly, preparing to give him a petrified petrified Peter when his name appeared on the map curse.
"I solemnly swear that I have done nothing wrong!" Harry gently raised the wand in his hand, ready to tap on the parchment in front of him.
"Wait a minute, we'd better not demonstrate here." Ron hurriedly stopped Harry, and said in a hurried voice, "There are too many people in the auditorium, if someone finds out..."
"It's okay, as long as you're careful, you'll be fine. I want to see if this map is as magical as Harry said." Ivan looked at Ron with some understanding.
Ron turned his head and glanced at Ivan, the expression in his eyes was indescribably weird, his eyes quickly left again, and moved to the Marauder's Map again.
"Ivan is right, as long as we are careful, we won't be discovered." Harry said, pointing his wand to the parchment, "I solemnly swear that I did nothing wrong."
"Oh, my God!" The next second, Hermione covered her mouth and exclaimed.
All eyes turned to the parchment, and Ivan saw the thin ink lines like spider webs on it, which immediately began to appear from the place where Harry's wand had just touched. These lines meet and intersect each other and extend to every corner of the parchment; then writing begins to appear on the top of the parchment, in large curved green letters, which read: Supplementary Supplies to Makers of Magical Mischief, Moon Face, Worm Gentlemen Tail, Padfoot, and Prongs proudly present the Marauder's Map.
Although he already knew it, Ivan was still surprised.
I don't know how Harry's father and the others made the Marauder's Map in the first place. Judging from Ivan's current knowledge, in order to make such a map, in addition to being extremely familiar with the terrain of Hogwarts, It also requires extremely advanced knowledge of Charms, Transfiguration, ancient magic literature, and name magic.
These theoretical knowledge are just the basics. The most important point is that there needs to be a very strong source of magic power, so that it can integrate the maker's thoughts on this parchment like the sorting hat.
Needless to say about the sorting hat, the Big Four are naturally capable of providing those magic powers.
Although the magic power required to make the Marauder's Map is far from that of the Sorting Hat, it is not something that ordinary wizards can provide.
But thinking that James Potter, Sirius Black, and Pettigrew Peter were all able to complete the Animagus when they were students, it seems that there is nothing surprising about making the Marauder's Map. Aiwen, who has already mastered Animagus, knows that this spell requires an extremely large amount of magic power during the first transformation process, and he also relies on magic enhancement potions to complete this spell.
What do James Potter, Sirius Black, and Pettigrew Peter rely on
Especially Peter Pettigrew, his magic talent doesn't seem to be very good, but he still completed the Animagus and successfully turned into a mouse.
Aiwen originally thought that they relied on a large amount of potions to replenish magic power to complete this spell, but now it seems that this is not the case at all. Magical items such as the map of the living point cannot be made simply by relying on potions.
They must have found another way, maybe they can ask Sirius Black in the future.
