At this moment, there was a sudden light not far away. It turned out that a door was opened and the light from inside came out.

Then there was the sound of stones rubbing against the ground and the sound of someone's footsteps.

Harry took two steps and couldn't help looking back at the gargoyle that had jumped back to its original position, and sighed softly.

He originally wanted to use Slughorn's memory to save himself from being put in solitary confinement. In his opinion, this was a sure thing, but he did not expect it to fail.

"I'm glad you got this memory, Harry. If you want, I can give you an extra reward, but it won't help you escape punishment. These are two different things that can't be easily offset."

Dumbledore said so.

This meant that he would still have to go to Professor McGonagall's office for detention every Saturday and would no longer be able to participate in the last crucial Quidditch match.

The only thing that made him feel fortunate was that Kyle seemed to have other things to do and would not participate in the competition for the time being.

Because everyone only had one game left, Hufflepuff and Gryffindor were far ahead in points, with only a 10-point difference between the two sides.

In other words, whichever team gets the higher score in the final game will have the chance to win the final championship.

Now that both sides are missing a key player, no one is at a disadvantage.

"I hope Kyle still won't participate in the competition by then." Harry sighed and turned to walk towards the common room.

Due to the time, there were not many people in the common room, but Hermione and Ron were still there, and judging by their looks, they seemed to be waiting for Harry.

"What took you so long?"

"So, Headmaster Dumbledore didn't expel you, did he?" Hermione asked.

"No." Harry shook his head, "But he deducted 100 points from me, and I have detention on Saturday, in Professor McGonagall's office."

"It's OK as long as he's not expelled." Ron was very open-minded. "It's just a point deduction and detention. Our school is already ranked last, so another 100 points deduction is no big deal."

"It's not the grades that matter," said Harry. "It's that I go to Professor McGonagall's office every Saturday."

"So what, you...wait a minute." At this moment, Ron suddenly realized something. "You mean, you have to be detained every Saturday?"

"That's right."

"What about the last Quidditch match?" Ron asked hastily.

"There's nothing I can do." Harry spread his hands.

"How could the headmaster do this..." Ron said anxiously, "It's related to whether we can win the Quidditch Cup! "Can you talk to him again? Maybe he will agree to let you participate in the competition."

"Stop talking nonsense, Ron." Hermione pushed him away. "What do you think the headmaster's decision is? Your homework? Can he change it just like that?"

"But Gryffindor hasn't won the Quidditch Cup for more than ten years." Ron looked at the ceiling and said weakly, "This year is obviously the most promising year!"

"I can't help it." Harry lowered his head. "Don't worry about it for now." Hermione interrupted the two people's sighs, "How about that memory, have you handed it to Headmaster Dumbledore?"

"Of course, thanks to you, Hermione, otherwise I might not have gotten it," said Harry.

"That's because you already have the ability to convince him," said Hermione. "The effect of the Felicis Felix only helps you adjust the environment. If it were me or Ron, even if we drank a pint of Felicis Felix, we wouldn't necessarily be able to get Professor Slughorn's memory from him."

"But the environment is exactly what I lack." Harry said, "Anyway, thank you. As for the Felicis Felix, I will find a way to return it to you."

"You're talking nonsense. You don't have to pay it back," said Hermione. "But what is that memory?"

"That's what I was going to tell you." Harry suddenly looked around. "Follow me."

He came to the row of armchairs in the corner of the common room and sat down, lowering his voice and saying, "Slughorn told Voldemort how to make a Horcrux."

"So it's really him?" Hermione covered her mouth, her face full of disbelief.

"Yes, it was he who told Voldemort that the creation of a Horcrux required killing to split his soul."

Afterwards, Harry told them what he saw in his memory.

To be honest, there wasn't much content in this memory. It was just a conversation between Slughorn and young Voldemort, which lasted only about ten minutes.

But after reading the memory, Dumbledore pondered for more than half an hour, and then looked... relieved and excited.

After listening to Harry's description, Ron couldn't help asking, "You mean, Dumbledore looks happy?"

"That should be it." Harry nodded. "He even said a few words to himself at the time."

"What did you say?" Hermione demanded.

"Let me think about it..." Harry frowned and carefully recalled Dumbledore's look after he came to his senses.

"He said at the time... 'This memory confirms my speculation. My guess is right and it will succeed soon... Tom, Tom, you must not have expected it.' That's about it."

"Who is this Tom?" Ron asked puzzledly.

"That was Voldemort's name when he was young," said Harry. "I remember telling you before that Voldemort's original name was Tom Riddle."

"If you could call me something else, maybe I'd remember it," Ron muttered.

His legs trembled when he heard the word "Voldemort", so how could he remember what Harry said afterwards?

"You can't do this, Ron, be brave, it's just a name." Harry said seriously: "You need to learn to get used to it."

"Oh, yes, I'll try," said Ron, but his tone was perfunctory.

Getting used to calling Voldemort's name? That was easy to say, but he was sure that 80% of the people in the wizarding world couldn't do it.

"It's almost successful?" Hermione sat in the armchair and looked at Harry puzzledly, "What does this mean?"

"I don't know. Professor Dumbledore didn't tell me." Harry shook his head. "After that, he let me leave and told me to meet him in the Great Hall at 7 o'clock tomorrow morning. He said he would take me to see something different then... It was a reward for getting my memory."

"Hermione." At this time, Harry suddenly turned his head and said, "Why don't you go tomorrow morning? If it weren't for your Felicity Potion, I wouldn't be able to get my memory. This reward should be yours."

"No, Harry." Hermione shook her head. "As I said just now, you were the main factor in convincing Professor Slughorn. The Felicity Potion only played a supporting role, so the reward should belong to you."

The two of them are blaming each other?

"But……"

Harry wanted to say something else, but was interrupted by Hermione.

"It's decided." She stood up and said, "Besides, it takes you an hour or two every time to go to the principal's office. Who knows if it will be the same tomorrow? The first class tomorrow morning is Transfiguration, and I don't want to be late."

"Okay then." Seeing Hermione say that, Harry had no choice but to agree.

"If you change your mind, feel free to tell me."

"No." Hermione waved her hand firmly.

Then the three of them returned to their dormitories.

the next day.

Harry struggled to get out of bed early in the morning and yawned as he came to the Great Hall. He rarely got up so early since his second year, and he was a little uncomfortable for a while.

From a distance, he saw Dumbledore standing there, and next to him was... Kyle? Apparently, after missing him many times, Dumbledore finally managed to catch up with Kyle on the first morning after the holiday.

The timing was just right. When he arrived, Kyle had just finished breakfast and was about to go to the eighth floor.

"Professor Dumbledore." Harry trotted over, "Kyle, you're here too."

"Hello Harry," said Kell, looking towards Dumbledore. "So Harry is the one we are waiting for, is that right?"

"That's right." Dumbledore nodded. "I hope you can forgive me for taking the initiative."

"That's okay," Kyle said, "but... never mind, do you want to have breakfast first?"

"Breakfast?" Harry touched his stomach.

He was indeed a little hungry, but he didn't want to make Kyle and Dumbledore wait for him. After thinking about it, he simply took two sandwiches and prepared to eat while walking. At least this way he wouldn't waste time.

The three of them came to the eighth floor together again. Kyle, who was in the front, turned a few corners and stopped in a corridor.

Harry was very familiar with this place. When he was about to remind Kyle that the Room of Requirement was broken and no one could get in, he saw Kyle took out a strange-shaped door knocker and stuck it on the wall.

The next second, a door suddenly appeared on the wall.

The Room of Requirement? Harry was dumbfounded, staring at the scene in front of him speechless.

What's going on? Does the Room of Requirement now require a key to open?

Never heard of it.

Besides, he also wanted to get a copy of this key.

It wasn't until everyone else entered the door that Harry reacted and quickly followed in.

Then Harry was shocked again.

He felt like he had entered another Hogwarts, everything was so familiar.

"Is this the memory of Rowena Ravenclaw?" Dumbledore was surprised as he looked at the students coming and going. "It's amazing."

And from his words, Harry also grasped some key information.

Whose memory?

Rowena Ravenclaw?!

Could it be that this place is the same as the Pensieve in the headmaster's office? Harry couldn't help but reach out and touch the wall next to him. It felt cold, it was real.

He tentatively approached a person who looked like a student, but the person passed through his body like a ghost.

But he didn't look like a ghost at all. After all, ghosts didn't walk on legs. They all floated, and there was no color on them other than pearly white.

"New here, please be careful when walking." The man turned his head and said dissatisfiedly.

"I'm sorry." Harry apologized subconsciously.

So this is really a memory?

He was a little bit unbelievable. When he experienced those memories in the Pensieve before, no one could see him, let alone communicate with him.

But when Harry saw that Dumbledore also had a surprised expression on his face, he felt relieved.

Fortunately, he is not the only one who has never seen the world.

On the other hand, Kyle beside him was very calm, as if he had known it for a long time.

"You can walk around." Kyle walked over and said, "There are classrooms upstairs, and professors are giving classes. They are all courses from thousands of years ago. You can go and take a look."

Harry nodded and left.

However, he did not go to the classroom. Instead, he wandered around the castle curiously, just like when he first entered the first grade.

He went to the Gryffindor common room, but instead of the familiar Fat Lady, there was another painting of a tall knight holding a two-handed sword.

Because Harry didn't know the password, the knight refused to let him in.

There was no choice but for Harry to leave and go somewhere else.

For some reason, he found himself in the corridor where the Room of Requirement was located.

Harry looked at the empty wall, then he closed his eyes and began to pace back and forth: "I need a broom shed... I need a broom shed... I need a broom shed."

He walked back and forth three times in front of the empty wall, but when he opened his eyes, he did not see the door.

That's right...this is the Room of Requirement, how could there be another Room of Requirement?

Harry shook his head and left.

At the same time, Dumbledore also came to the place that interested him.

About three hours later, or maybe longer, the three of them returned to the hallway and prepared to leave.

"Harry, how do you feel? Do you understand?" Kyle asked.

Harry's face suddenly froze.

"It's okay." He stammered.

He didn't go to those classrooms at all... That's not the right way to say it. It should be said that he stayed there for ten minutes, but didn't understand anything, so he left again.

Because of this, the professor got furious and scolded him.

Harry had never thought that memories could become so real, and subconsciously he treated this place as a Pensieve, where he could do whatever he wanted and no one would notice, including suddenly leaving in the middle of class.

So when the book that was thrown at him went through his head, Harry's legs went weak, and he never went to those classrooms again. Instead, he spent the whole morning touring the place carefully.

But seeing his guilty look, Kyle could probably guess what was going on, so he nodded and didn't ask any more questions.

He looked at Dumbledore.

"It's very interesting. It solves some puzzles that have troubled me for many years. For example, how long have those portraits been in the school? I have always been curious about this." Dumbledore said, "But there is one thing that is very strange."

"What?"

"I saw Slytherin in the Chamber of Secrets and Hufflepuff in the kitchen, but I didn't find Gryffindor."

Dumbledore asked, "He doesn't seem to be in this castle, but if I remember correctly, Gryffindor seems to be the most active of the Big Four, and he also served as a professor for a period of time, teaching students in person."

"This..." Kyle opened his mouth.

He couldn't tell Dumbledore that Godric Gryffindor had been erased from Ravenclaw's memory because of some disgraceful behavior.

Dumbledore also graduated from Gryffindor House. He could accept that the founder of the house was a pervert who liked to use a sword to pick people's belts... Well, is it weird?

For the sake of the Big Four's reputation, Kyle hesitated for a moment and said, "Maybe he's not in school during this period."

"Really?" Dumbledore didn't think much about it.

When the three of them walked out of the Room of Requirement, the door on the wall immediately disappeared.

"I heard from Harry that you learned the magic that turned him and Malfoy into some kind of animals from here," Dumbledore asked.

Harry looked over too.

Hermione had said before that Kyle had seen this spell in the library, but now it was clearly not the case.

"Right." Kyle nodded and said, "In the Charms class on the second floor, Professor Lagor thought this was a very effective trick."

"This is not a trick." Dumbledore said with a smile, "If you face an enemy who doesn't understand runes, any magic he uses will become your aid, and the number of people will no longer be meaningful."

He turned his head to look to the other side, wanting to ask Harry to learn from him, but stopped at the words.

Never mind. Some things cannot be forced. Harry is doing pretty well now. At least he can fight against most Death Eaters.
