After the conversation with Professor McGonagall, Felix simply assigned an assignment on a topic similar to the essay Harry and Hermione had written - what are the things that can help you get through a crisis when you are in danger?
"Whether it's character, knowledge, mastery of a spell, something to carry with you, you can write about it." The new prefects' of the male and female student bodies passed those words on to the selected students.
Over the next week, numerous professors combined their efforts to complete a large project, while he spent most of his free time in the Room of Requirement - mapping out the magic and magical channels on it - and now only the final step remained.
Dumbledore and Felix stood in the empty room, where there is no longer any morphed out slopes and greenery, nor any trace of the different arenas from the dueling tournament, even the black hovering door that was used to select candidates a week ago, has disappeared.
All that remained in the room was the Undetectable Extension Charm that Felix had placed in it, making the interior space comparable to ten Quidditch courts. Hogwarts would have been perfectly fine with people from other schools living here if they hadn't considered what the other four schools had in mind.
With heavy reinforcement and protection magic applied by the professors, every inch of this old room had been infused with powerful magic. They added some extra defensive measures on top of that.
Right now, there are only two of them in the classroom, engaged in a serious conversation -
"What do you think?" Felix inquired.
"It's worth a try." Dumbledore said relaxedly.
"I never thought that I would be able to integrate my magic into the defense system of Hogwarts that existed for a thousand years and millennia from now ..." Felix went into a momentary trance in his mind, and when he looked back, Dumbledore is looking at him with a smile.
"Let's get started, Albus, I'm afraid the students outside can't wait any longer." Felix said as he tightened his grip on his wand.
Dumbledore obeyed, he raised his wand, waved his arm like a conductor in an orchestra, and communicated with the old castle in a way that Felix could not understand.
"Buzz~"
He did not know if it was an illusion, Felix felt the castle under his feet come to life. Like a slumbering dragon turned slightly on the side, which made the small creatures that nested and burrowed in its body as they parasitized on the scales, found that the whole world shifting.
Clusters of magic power turned solid, purple, blue, yellow, blue, bronze, green, gray ... converged and quickly separated from each other, forming a flower of magic power.
"Felix--" Dumbledore said in a deep voice.
Felix understood by heart that he needed to get these magical powers fixed and form a solid link - just like the Room of Requirement.
A small fluffy silver ball appeared in his hand, like the fluffy puffskein, and a collection of clustered neural networks emerged from the fluffy ball, with occasional flashes of light blue electricity, it slowly floated into midair, then quickly expanded into a three-dimensional structure, occupying the entire spacious room.
Felix recited a complex incantation, allowing these nodes and core links to be integrated into this space, like synapses, which drew on the magical power of the castle and stabilized their magic nodes.
After that, everything disappeared. Magic, nodes, core links... they totally integrated with the room.
Felix switched his perspective, to locate those nodes and concealed them one by one, making it difficult for even powerful wizards to discover them. Dumbledore did the same thing, he also laid out a stable magic channel from the authority that no one can know and belongs only to the Headmaster.
As long as Hogwarts exists, as long as it is still enrolling students, this place will never disappear, just like the Room of Requirement.
Dumbledore finished all this and found four more stone basins of thoughts' in front of Felix.
"Is this ...?" He asked curiously, with a certain guess in mind.
"It's the memories of Professors." Felix said briefly.
He took a deep breath, everything before was to create a suitable environment, the next step is the main part, although this step is not much difficult, he could not help but be nervous.
Felix controlled the four stone basins of thought with each flew towards four different directions, making it look as if the room had been divided into four zones, with a stone basin suspended in the center of each area.
"What's the point of doing this?" Dumbledore asked with interest, even for him, this is a rare large-scale practical magic project, a rare fusion of alchemy with memory magic and transfiguration in the magical world.
"Adding a bit of ritual." Felix smiled and said, then his tone became serious, "So - the first administrator, seventeen-year-old Albus Dumbledore."
The stone basin to the left of the two exploded and countless dense silver clouds poured out from it, followed by a tall, thin young student with reddish-brown hair stepping out.
His long, slender fingers held a wand, as he lightly swiped to the left and right side respectively, the fog split in two. The young Dumbledore had gleaming blue eyes, with a twinkle of kindness and mischief behind it.
"Old pal, you did not give me much knowledge, my head is empty, how will I face those troublesome students?" The young Albus said so, although it seems that he was complaining, but he did not seem to be bothered, instead, he smiled and nodded towards Felix.
Dumbledore looked at him, his eyes moistened, as he murmured: "This is when I just graduated, young with vigor and ambition, thinking that I have a bright future ..." He shook his long silver beard and smiled. "Oh, I don't know if I had mentioned it before, I was very fond of Bertie Bott's Every Flavour Beans when I was young."
The young Albus Dumbledore was waving his wand, setting off a wild silver ripple, a fog like a condensed wave, settled in midair, then they morphed, forming an open-air square platform, with numerous red and gold adornments dotted around.
Felix and Dumbledore watched for a moment, then turned to the other side, and Felix whispered, "The second person who selflessly provided her memories - Minerva McGonagall."
The second stone basin of thought exploded into powder. A beautiful young lady appeared in that spot, with thick black hair, about thirty years old, she had green glowing eyes. This is the young Minerva McGonagall, in which you can see more of the shadow that belongs to the Hogwarts Transfiguration Professor, with a serious expression, her hair pulled up high into a bun, as she's wearing a pair of square-frame glasses.
"That's interesting ..." she looked around, her lips pursed iconically, "Let me think about what I need to do, Minerva left me with a list of tasks."
With that, she didn't move a muscle.
The third person to appear is a younger Filius Flitwick, who is also considerably younger than the current Hogwarts Charms class professor, without his gold-rimmed round glasses and with a lot fewer wrinkles, he is dressed in a dignified, rigorous suit.
According to himself, it was the suit he had worn when he had won the wizard dueling championship.
"Oh, Felix, Albus ...," the young Flitwick bowed slightly and waved the wand in his hand gracefully, "Welcome, I don't think you are in the mood for a duel at the moment, but I will be right here, awaiting you at all times."
The last stone basin blew open, and a young Felix stepped out, he looked exactly the same as he did now, only with a somewhat more flippant expression, he looked at Felix and reached out to point at him, "I need to talk to you, you're putting too many restrictions on me."
"Oh, you don't need to." Felix muttered, letting a silvery cloud cover him up.
...
Felix said to Dumbledore, "They will not be around often, but as administrators of this secret domain. Their task is to make this place more active as well as manage and control those adventure sites. Of course, I'm talking about after the training."
Dumbledore nodded slightly: "You've talked to me about all this, I have no problem with it."
They walked out of the room together, a dozen students anxiously waited outside, as a little girl shouted loudly: "Why am I not on the list? Why?"
Professor McGonagall is comforting her by saying, "Greengrass, you're too young for this. ..."
"I'm the champion! A champion!" Astoria shouted.
Professor McGonagall looked at her with a headache, when Dumbledore came over and said gently, "You are little Astoria? Your father sent me a letter, let's check it out together, and by the way, I can recommend a few new sweets ..."
"Really?"
"Professor McGonagall can vouch for me ..."
On the side, McGonagall rolled her eyes, but the issue is finally solved. Turning to Felix, she said, "I'll leave these students to you, Felix, I think-"
She thought for a moment and didn't say anything further. As she turned around and left.
Felix looked at the youthful faces, "All right, students, take your essays and follow me in."
He took a few steps forward, and halted, looking at the half-open door of the room, drew his wand and outlined it in the air, and a line of gold-stamped letters appeared above the door - "Classroom Seven."
Harry, Ron, and Hermione looked at each other and Harry shrugged, "Now that's a name."
