At the same time, Ivan and Hermione were waiting in the dark corridor on the eighth floor with the Marauder's Map.
On the map is the entire Hogwarts scene, and the moving black dots are marked with names, showing the location of each person.
The core of the operation of the Marauder's Map is name magic, and everyone's name is inherently magical.
This kind of magic power is not visible, but it really exists, just like constellations and blood types, it will have a subtle influence on a person.
Aiwen has conducted research based on the Marauder's Map. Now he can use a little fur of this name magic to track a person through potions or spells to determine the location of the person. He once used it on Peter Pettigrew.
Therefore, as long as Peter is alive, Ivan will sense him and track him in the forbidden forest at night.
With the strength of the magic power, this induction has a distance limit, just like the Marauder's map can only show the inner area of Hogwarts.
And it's not so reliable. The experience of the last semester told Ivan that as long as the wizard whose name has been processed like Keresis, he will not be tracked by the magic mark of the name. In other words, he will not appear on the Marauder's map .
Still, it was fine to use it to see where Umbridge, Filch, and the rest of the group were.
They certainly don't cast spells on their names, don't have that ability.
"Harry and the others are finished training, and the members are returning to the castle." Ivan said, looking at the Marauder's Map in hand, "Well, it's a bit strange, Harry and Ron have stayed in the locker room and haven't come out, what are they doing secretly? ?”
"I don't know, but I hope they hurry up!" said Hermione, leaning over. "Where's Umbridge?"
"In her office." Ai Wen said, "She didn't even eat dinner, and she didn't come out of the office. Don't be so nervous, no one informs, she won't know what we are going to do. Ah, they come Alright, let's go in first, Harry knows how to get into the Room of Requirement, and the two of them will get in by themselves."
A group of people climbed up to the eighth floor, everyone looked extremely nervous, with a little anxiety in the suppressed excitement.
After seeing Ivan and Hermione, they were relieved.
"It's enviable that you two are clean and dry." George said, and the new clothes were also damp. "I'm almost drowned!"
"There are worse things..." Fred clutched his ass.
"You guys train in this weather?" Michael said in surprise, looking at Ginny, who was also wet.
"Yeah, to win the Quidditch Cup, it takes a certain effort, doesn't it?" Angelina answered him, "I think our training is very necessary, and no one can guarantee that we will meet in the official competition." Whatever the weather, if it's rainy, we'll be prepared!"
"Please, I don't want to talk about Quidditch training, Ivan, where is the secret room you mentioned?"
Everyone looked around curiously. Students, especially Hufflepuff students, rarely come to the eighth floor of the castle. After all, there are no other classrooms except the principal's office. Many people are in awe of the principal. Usually they don't come to him.
Dumbledore has no specific teaching tasks, and most students may only see him twice a semester, at the beginning and end of the semester dinner.
"Come on, it's over there!"
Alvin and Hermione led them through the corridor to the huge tapestry where the silly Barnabas tried to teach the troll to dance the ballet. Opposite the tapestry was a section of white wall, and a moth-eaten troll stopped Beat up the ballet teachers and look back at them.
"Here, it's here!" Ai Wen said, "This is the Room of Requirement, walk through this wall three times back and forth, and concentrate on thinking about what we need. Remember, we now need a room for learning magic and practicing fighting. Come."
Since the first grade, Ivan has used the Room of Requirement as a place to brew potions.
This room is amazing, no matter what he needs, he can change into a corresponding room, with everything in it.
Even not long ago, Aiwen needed a workshop for making brooms, which could be transformed, including various tools.
Ivan conducted research on the Room of Response and asked the professors. The final result of the research is that no one can use the magic involved in this room. As for who left it and how it was made, there is no way to figure it out.
Apart from the secret treasures left behind by the four founders, this room has the potential to be Hogwarts' greatest secret.
Everyone followed Ivan, walked to the window at one end of the white wall and turned back, and turned back at the vase that was one person tall at the other end.
"We need a place to learn magic and fighting, and give us a place to practice without being discovered."
These thoughts seemed to be picked up by this section of the wall, and after they went back and forth three times, a smooth door appeared.
"Okay, come on!" Ivan said, opened the door, and led into a spacious room.
The inside is completely built of large cyan rocks, with torches lit, just like in an underground classroom.
There is a row of wooden bookshelves by the wall, and there are no chairs on the floor, but there are large satin cushions.
On a shelf at the other end of the room were various Auror-used instruments such as sight glasses, spy-spots, and traps, as well as a large cracked demon mirror that was believed to be the one that hung in the fake Moody's office last year. noodle.
After Mad-Eye came back, the demon mirror was thrown away, and no one knew how he appeared here.
"It's amazing here!"
"Yes, everything that should be available, everything is available!"
"It's great that there's still food!" Fred said. "Well, it's still hot. Are these things edible?"
"I don't think there is a problem!" Ivan said. "Some of you must be thinking about what you want to eat just now. All these cakes and hot drinks will appear. This room can meet the needs as much as it can, so it is called the Room of Response."
"It's me, I didn't eat anything in the auditorium just now." George said, picking up a piece of cake and stuffing it into his mouth.
"Look at these books!" Hermione excitedly stroked the spines of rows of thick sheepskin-bound books, "I was just wondering if I should add some books on fighting, and they just appeared. I'm sure some There are no books in the library, "Common Spells and Solutions", "Outwit Black Magic", "Self-Defense Charms Collection"... "
She looked back at Ivan, her face glowing, thousands of magic books made Hermione forget all her worries.
"Great, we have everything we need."
She immediately pulled out "Fighting Drugs with Poison" from the bookshelf, sat down on the nearest cushion and began to read.
