Dumbledore was in the office, looking at a document on the desk thinking about something.

In addition to the principal of Hogwarts, he also has many slash identities.

For example, the chief magician of Wisengamo, the president of the International Wizards Federation, etc.

Therefore, he not only had to deal with Hogwarts' official duties in daily life, but also had to focus more on matters that had nothing to do with Hogwarts.

Seeing Sherlock walk in, he raised his head, put down the quill in his hand, and smiled at him.

“Want to have some dessert for afternoon tea?”

As soon as he finished speaking, a small pile of cookies and two cups of steaming black tea suddenly appeared in an empty silver plate on the desk.

"Thank you, professor, but I just came back from three broom bars and finished afternoon tea with Professor Sprout and others."

Sherlock said and went opposite Dumbledore.

Dumbledore asked, picking up the teacup and taking a listener's gesture.

"So since you are not here to have afternoon tea with me, is there anything wrong with me?"

Without unnecessary politeness or striking around the bush, Sherlock directly expressed his purpose.

"It's about the constant attacks in the castle starting this semester, Professor."

"Oh? What did you find?"

"The incident at school has leaked the news outside, and today I heard a rumor in the bar that I don't know whether it is true or false, so I came to you to confirm its authenticity."

Sherlock's face was solemn, and he could hear his current attitude in his voice.

After Dumbledore's tea cup was lifted, he heard his words and put them back, and he asked softly.

"So the content of this rumor is..."

"Fifty years ago, Slytherin's secret room was opened, and at that time Hagrid was fired."

Sherlock said calmly, without questioning Hagrid in his words, he just wanted to use this matter to Dumbledore for verification.

After hearing Sherlock's words, Dumbledore was not silent or wanted to hide anything. He nodded calmly, as if he was talking about a trivial matter in Hogwarts where a student had another fight again today.

"Yes, this rumor is true. It was indeed fifty years ago, when I was not the principal of Hogwarts. Although I really wanted to stop them from splashing the dirty water on Hagrid, I was powerless and could only let him stay in school first and not be homeless."

"So, the secret room was really opened? Hagrid was also implicated?"

Sherlock frowned. He didn't expect that the secret room would involve three timelines, the ancient times when the four giants founded Hogwarts, fifty years ago, and now.

This time, Dumbledore did not reply to Sherlock immediately, but watched him quietly fall into a brief meditation.

Sherlock did not bother him, waiting for him to think.

After a moment, Dumbledore stood up from his chair as if he was about to make a decision.

"Since you already know this, are you interested in seeing what happened back then with your own eyes?"

His blue eyes were clear and bright, and he invited her to Sherlock.

Sherlock nodded without hesitating for long, indicating that he really wanted to know what happened at that time.

Dumbledore took out a basin made of stone from the cabinet in his office and placed it on the desk.

Then, he aimed his wand at his temple, gently rotated the wand, and pulled out a silver thread of light from his mind like a thread that was pulled, and pulled it into the stone basin.

"I sometimes pull out my thoughts in Hogwarts' meditation basin and put them here to sort them out so that I can see more things clearly. Now, it also allows us to look back on the past."

As he said that, he looked at Sherlock and guided him.

"You can put your face into the basin."

Sherlock walked into the meditation basin, looked at the silver shavings wandering inside, bent down, and slowly buried his face in.

The next moment, a sense of weightlessness falling from the air came, but soon his feet stepped on the solid ground again.

The darkness dissipated around her, and Sherlock realized that he had come outside the corridor of Hogwarts.

The sky outside became dark at some point, only torches hanging on the ancient mottled walls illuminated the surrounding space.

After a while, Dumbledore also landed next to Sherlock.

Looking at the surroundings of Hogwarts, but completely inconsistent with the previous one, Sherlock asked after taking a breath of ancient air.

"Is this Hogwarts fifty years ago?"

"To be precise, it is Hogwarts fifty years ago in my memory." Dumbledore said softly.

Just as his words were finished, a tall wizard with auspicious flowing long hair and a long beard, who looked a little like Dumbledore by their side.

Dumbledore signaled Sherlock and they followed the wizard together.

"Is this you when you were young?" Sherlock's tone was filled with surprise.

Dumbledore nodded slightly.

"Yes, I was just a deformation professor in Hogwarts at that time."

Sherlock did not continue to ask more questions, and they followed the young version of Dumbledore to the foyer on the first floor.

Here, a handsome boy with a long badge on his chest happened to meet the young Dumbledore, and he greeted the male student.

"What are you doing, Tom, still wandering around so late?"

The boy named Tom was very calm and calm, and he replied.

"I'm going to see the principal, sir."

"Okay, go to bed soon." The young Dumbledore stared at Tom with the same penetrating gaze as he was when he was old. "Don't hang out in the castle these days, since it has happened..."

He shook his head with a sigh and did not continue to say anything, but Sherlock heard the metaphor in his words.

"At this time the attack had already happened, and some students died because of this?" Sherlock asked Dumbledore beside him in a deep voice.

Dumbledore nodded heavily, too.

"Yes, Hogwarts had already begun to plan to close the school."

While they were talking, the young Dumbledore had said good night to the student named Tom, and the two separated.

But at this time Dumbledore grabbed Sherlock's arm and did not continue to follow himself when he was young. Instead, he stood in front of the foyer and explained to him.

"Because this is my memory, we can't see what happened to others who were not present at the time. But you will soon see the final result."
