Just a Defense Against the Dark Arts Professor

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

Besides being the headmaster of Hogwarts, he has many slash identities.

For example, the chief magician of Wizengamore, the president of the International Federation of Wizards and so on.

Therefore, he not only has to deal with the official business of Hogwarts, but also devote more energy to things that have nothing to do with Hogwarts.

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

"Want 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 got back from afternoon tea with Professor Sprout at the Three Broomsticks."

Sherlock said and sat across from Dumbledore.

Dumbledore raised his teacup and asked as if he were a listener.

"So since you didn't come to accompany me for afternoon tea, why do you come to see me?"

Without any extravagant politeness or beating around the bush, Sherlock directly stated his intentions.

"It's about the attacks that have been happening in the castle since the beginning of the semester, Professor."

"Oh? What did you find?"

"The things in the school have been leaked outside, and I heard a rumor in the bar today that I don't know if it's true or not, so I came to you to make sure it's true."

Sherlock's face was solemn, and his current attitude could be heard very seriously in his voice.

After Dumbledore's teacup was lifted, he heard his words and put it back again, he asked softly.

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

"Fifty years ago, Slytherin's Chamber of Secrets was opened, and Hagrid was fired at that time."

Sherlock said calmly, he didn't mean to question Hagrid in his words, he just wanted to ask Dumbledore to verify this matter.

After listening to Sherlock's words, Dumbledore didn't remain silent or wanted to hide anything. He nodded indifferently, as if he was talking about a trivial incident in Hogwarts about which student fought again today.

"Yes, the rumor is true. It was indeed fifty years ago, when I was not the headmaster of Hogwarts, and although I wanted to stop them from throwing that dirty water on Hagrid, I didn't. Incompetent, I can only let him stay in the school first, so that he will not be homeless."

"So, was the Chamber of Secrets really opened? Hagrid was implicated because of this?"

Sherlock frowned. He didn't expect that the Chamber of Secrets would actually involve three timelines, the ancient times when the Big Four created Hogwarts, fifty years ago, and now.

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

Sherlock didn't bother him, waiting for him to think.

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

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

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

Sherlock didn't hesitate for long, then nodded, indicating that he really wanted to know what happened at that time.

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

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

"The Pensieve at Hogwarts, I sometimes take my thoughts out and put them here to organize them so that I can see more things clearly.

Now, we can also look back on those past events. "

Saying that, he looked at Sherlock and guided him.

"You can stick your face in the basin."

Sherlock walked in front of the Pensieve, looked at the silver shavings wandering inside, bent down, and slowly buried his face in it.

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

The surrounding darkness dissipated, and Sherlock found himself outside the corridors of Hogwarts.

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

After a while, Dumbledore also fell to Sherlock's side.

Looking at the surroundings at Hogwarts, but completely inconsistent with the previous environment, Sherlock took a breath of ancient air and asked.

"Is this Hogwarts fifty years ago?"

"To be exact, the Hogwarts that I remember fifty years ago," Dumbledore said softly.

Just as his voice fell, a tall wizard with long flowing auburn hair and long beard, who looked a bit like Dumbledore, passed by them.

Dumbledore gestured to Sherlock, and they followed the wizard together.

"This is you when you were young?" Sherlock said with surprise.

Dumbledore nodded slightly.

"Yes, I was just a Transfiguration professor at Hogwarts back then."

Sherlock didn't ask any further questions, and they followed the younger version of Dumbledore all the way to the foyer on the first floor.

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

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

The boy named Tom was very composed, he replied.

"I was going to see the headmaster just now, sir."

"Okay, go to bed." The young Dumbledore stared at Tom with the same penetrating eyes he had seen in his older years, "Don't hang out in the castle these days, since it has happened. …”

He shook his head with a sigh and did not continue, but Sherlock could hear the metaphor in his words.

"The attack has already happened at this time, and a student died because of it?" Sherlock asked Dumbledore beside him in a deep voice.

Dumbledore also nodded heavily.

"Yes, at this time, Hogwarts has already begun to plan to close the school."

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

But at this time, Dumbledore grabbed Sherlock's arm, and instead of following his younger self, he stood in front of the hall and explained to him.

"Because it's my memory, there's no way for us to see what happened to other people who weren't there at the time. But soon you'll see the end result."

Not long after Dumbledore finished speaking, a violent explosion suddenly sounded at the Hogwarts basement below their feet!
