As soon as Kael came out, they immediately turned their gaze neatly in his direction.
Kael smacked his lips and asked, "Professor McGonagall, what's this all about?"
"Everyone's curious," Professor McGonagall said, looking a bit embarrassed.
She had only intended to ask someone about the diadem, but inadvertently revealed more than she intended, and by the time she realized, everyone seemed to know the reason for Kael's absence.
A tutoring session with Rowena Ravenclaw—who wouldn't be curious about that, so they all came along.
"Of course, it's also for your safety," Professor Sprout added.
"No problem, come with me."
Kael didn't mind either.
The professors present were all on the inside, no outside snitches, so he could comfortably lead them together.
So, the four professors and Kael marched grandly towards the eighth floor.
Along the way, they attracted a lot of attention, with many speculating about what they were aiming to do.
Some even quietly followed behind, preparing to gather first-hand information.
But Professor McGonagall simply turned her head, swept a blank-eyed gaze around, and they instantly gave up the idea.
Upon reaching the eighth floor, Kael adeptly took a few turns, arriving at the middle of a corridor, where he placed the Raven Door Ring he was holding on the wall.
Then, to the professors' astonished eyes, a door appeared out of thin air.
"Does Hogwarts have such a place?" Professor Flitwick couldn't help but ask.
He had been a professor at the school for decades and had never known about this place.
But no one answered his question.
Because Kael had already opened the door and walked in, with Professor McGonagall following first, then Professor Babbling...
When they saw the scene inside the door, they were once again shocked.
It was the hall of Hogwarts, with the auditorium on the left and stairs directly in front, and except for some different decorations, everything else was exactly the same, even the students.
Was there another Hogwarts inside Hogwarts?
This made them a bit incredulous.
But professors are professors, experienced and worldly, they quickly calmed down, and they also noticed the differences between here and the school.
Everything around was very new, it should be Hogwarts from another era.
"That's truly incredible."
Professor Babbling placed her hand on the nearby wall, squinting as she quietly said, "This is simply constructed with Magic Text... oh, and maintained by the castle's Magic Power... it's such a vast project, remarkable!"
In their daily lives, or when using Charms, young wizards inevitably generate some excess Magic Power.
This Magic Power, generated in the castle, would then feedback into the castle; for example, the portraits on the walls, the talking armor, the rotating stairs, they all exist because of this Magic Power.
Of course, the Room of Requirement is the same.
In other words, when there are no students in the castle, the Room of Requirement ceases to exist.
"That's just the basics, the truly astonishing part is on the second floor." Saying this, Kael then walked up the stairs, leading the professors to the classroom he had his previous lessons in.
It was at this point that the professors understood what the so-called tutoring session meant.
An unknown professor in the classroom was earnestly teaching, and upon noticing the people outside the door, sternly reprimanded:
"What are you all still doing standing outside? Don't you know class has already started?"
Several professors who had worked at Hogwarts for decades never expected they would one day be chided in such a tone.
It felt just like when they admonished tardy students.
Even more awkward, they didn't know how to retort, and Professor Flitwick subconsciously walked in, recognizing that it was Charm Class.
"Did Rowena Ravenclaw do all this?" Professor McGonagall asked.
"Yes," Kael nodded and said, "This is the school in her memory, Hogwarts from a thousand years ago, and I can study here for a period of time."
This time, Professor McGonagall believed.
Weaving a real world from memory, such an incredible feat even Dumbledore couldn't accomplish... only the four founders could, probably.
Thinking of this, the remaining three professors shared a look, then very tacitly spread out, starting to search through the classrooms for something.
"You said it was for my safety," muttered Kael, left behind, his mouth twitching, unsure what to say.
But he anticipated this would happen, shrugged, and casually walked into a classroom.
Curiously, although he'd just spent a long time outside with the professors, when he entered, the class inside was just beginning and he hadn't missed any of the content.
