Harry nodded and left.
However, he didn't go to the classroom but wandered around the castle curiously, just like he did when he first started in first year.
He went to the Gryffindor common room, but instead of the familiar Fat Lady, there was another painting, a tall knight holding a two-handed sword.
Because Harry didn't know the password, the knight refused to let him in.
With no other choice, Harry left and went elsewhere.
For some reason, he found himself in the corridor where the Room of Requirement was located.
Harry looked at the empty wall and, as if by a strange impulse, closed his eyes and began to pace back and forth:
"I need a broom closet... I need a broom closet... I need a broom closet."
He walked back and forth three times in front of the blank wall, but when he opened his eyes, he didn't see a door.
Well... this is the Room of Requirement, after all, there can't be another Room of Requirement.
Harry shook his head and left.
Meanwhile, Dumbledore also arrived at a place that piqued his interest.
About three hours later, or maybe more, the three of them returned to the entrance hall, ready to leave.
"Harry, how do you feel, can you understand?" Kael asked.
Harry's face suddenly stiffened.
"It's, it's okay," he stammered.
He actually hadn't gone to those classrooms... or rather, he stayed for ten minutes but couldn't understand anything, and then left.
Because of this, that professor was furious and scolded him.
Harry never imagined memories could become so real, and he subconsciously treated it as the Pensieve, where he could do anything without being discovered, like suddenly leaving midway through a class.
So when the book thrown at him passed through his head, Harry's legs went weak, and afterward, he didn't visit those classrooms anymore but spent the whole morning exploring the place.
But seeing his guilty look, Kael could probably guess what was happening and just nodded without asking further.
He looked at Dumbledore.
"It's interesting. This place has solved some of the doubts that have puzzled me for many years, like how long those portraits have been in the school; I've always been curious about that," Dumbledore said, "but there's something strange."
"What?"
"I saw Slytherin in the Chamber of Secrets and Hufflepuff in the kitchen, but couldn't find Gryffindor."
Dumbledore asked, "He doesn't seem to be in this castle, but if I remember correctly, Gryffindor was the most active of the four founders, and even served as a professor for a while to teach students personally."
"Well..." Kael opened his mouth.
He couldn't really tell Dumbledore that Godric Gryffindor was erased from memory by Ravenclaw due to some unseemly actions, could he?
Dumbledore also graduated from Gryffindor House; would he accept his founder as an eccentric who liked to use a sword to provoke people's waistbands?
To preserve the reputation of the four founders, Kael hesitated for a moment before saying, "He might not be at the school during this period."
"Is it?" Dumbledore didn't think much of it.
As the three walked out of the Room of Requirement, the door on the wall disappeared immediately.
"I heard from Harry that you turned his and Malfoy's magic into some kind of animal; you must have learned that here," Dumbledore inquired.
Harry also looked over.
Previously, Hermione said Kael had seen this charm in the library, but now it seemed that wasn't the case.
"That's right." Kael nodded, "In the Charm Class on the second floor, Professor Lagoer thought it was a very useful little trick."
"That's not a little trick," Dumbledore said with a smile. "If you face an enemy who doesn't understand Magic Text, his magic will just become your aid, and the number of opponents will no longer matter."
He turned to look to the other side, intending to have Harry learn as well, but stopped the thought at the last moment.
Never mind, some things can't be forced; Harry is doing just fine now, at least he has what it takes to confront most of the Death Eaters.
