The white inscriptions on the black marble are easier to make out in the dim light, they seem to glow in the dark -

Rock Irwin

Born on December 12, 1966, died on May 3, 1980

Died of influenza after nursing 12 companions

" Rock Irwin ..." Felix murmured, recalling the scene when he was nine years old and collapsed in a hospital bed, at his weakest, someone kept taking care of him.

Three days before he recovered, Irwin's disappeared, and he pleaded the dean to tell him, only to be met with a heavy sigh..

That was the first time he understood death deeply.

Felix stood quietly in front of the tombstone, like a silent statue, and after almost an hour, his figure disappeared.

At eight o'clock in the evening, Felix returned to his office, where he had, earlier this morning, used his Patronus to inform his assistant that he had cancelled this weekend's magic tune tutoring.

With a little preparation, he knocked on the door of the Headmasters office.

The room is very dim, Dumbledore looked up from his desk and looked at him through his half-moon glasses, "Felix ... please sit down, wait a moment, the office is a little dark."

He held up something that looked a lot like a silver lighter, pressed a few times, a ball of light flew out of it, and the office immediately became brighter.

"What is this?" Felix asked with interest.

"I made a gadget, I call it a lighter, can absorb and release light sources," Dumbledore said.

Felix sat in front of him and pulled out the diary and the brand-new diadem.

The first thing Dumbledore's eyes fell on is the diadem, he stood straight up and bent down to examine it carefully, "This is ... if I'm not mistaken ..."

"That's right, Lady Ravenclaw's diadem."

Dumbledore looked at Felix and keenly noted his use of the word 'Lady', few people would use that.

He quickly thought of his Headmaster's authority being briefly borrowed, and the suspicion that sprang to mind horrified him a little, but he quickly ruled it out.

His eyes turned to the diary, an item that was much less eye-catching, looking tattered and torn, with a hole in the middle.

Dumbledore stared at it for a longer time, his fingers kept fumbling with the broken hole, "A powerful Fiendfyre curse," he frowned but did not rush to comment, and for a moment his azure eyes widened, "So that's it, yes, that's it ..."

After a long time, his eyes moved away from it. Dumbledore said with a soft admiration, "What a surprise to me, I thought, there will not be anything that can make me an old man surprised, it seems that your story will be a big eye-opener for me."

Felix began to recount his 'experience' from very, very early on, "The night the Chamber of Secrets adventure ended, I was approached by Draco Malfoy, who appeared terrified, yet very resourceful, bringing with him an evil dark magic item ..." He nodded to indicate the diary on the table.

He spoke of his suspicion that the diary had something to do with the opening of the chamber and tried to talk with it, but there was no trace of feedback.

"This is not quite consistent with Mr. Malfoy's experience, and I am going to observe it for a while and set up tight magical protection for it."

Dumbledore crossed his arms and rested them under his chin, listening quietly.

"Until the dueling class, I found that the ban I had set up was broken, rushed back and found a house-elf, his name is Dobby, I used the magic potion on him and accidentally obtained the truth about the incident of the chamber," Felix said.

"So--"

"The diary is Voldemort's relic, which he gave to Lucius Malfoy for uncertain reasons, and Lucius hid it in the Weasley's youngest daughter, Ginny Weasley's book, with the help of an accidental meeting in front of the Bookshop."

Dumbledore sighed, "Matches up with some of my suspicions, as far as I know, the Ministry of Magic searched several pureblood families during that time, under the guise of investigating dark magic items, Lucius may have been in a hurry and couldn't wait to get rid of the problem."

"Dobby harboured a huge debt of gratitude to Potter, and he went out of his way to disobey his master's orders to protect Potter in any way he could, even though ..." Felix gave a small smile, "it may have been troubling to Potter himself. "

"Ah, such pure emotion, often can exceed our imagination," Dumbledore said with emotion.

"Anyway, I realized the danger and prepared to destroy the diary, but regular magic simply didn't work, so I used the Fiendfyre," Felix said, profusely, did not avoid the fact that he used dark magic.

And Dumbledore did not say anything more: "Perhaps ... this is indeed a good way."

Next, Felix explained himself in the time of pursuing the secret room, had inadvertently found a mysterious room, "I think its magic is very interesting, ready to study in their free time."

"On the seventh floor of the castle, the tapestry of trolls beating Barnabas with a club?" Dumbledore repeated, showing a thoughtful expression, he smiled and said: "Your words have unlocked a long-time suspicion."

"You know it too?" Felix asked knowingly, he couldn't say that he had done all sorts of strange and bizarre tests using your name, right?

"Oh, it was a wonderful experience, but perhaps I underestimated its use at the time ..."

Felix did not press the issue, he nodded and spoke again about the two ghosts, he and Baron knew each other when they were at school and had overheard a conversation between them.

He said with some shame: "Initially I had a utilitarian purpose - I saw the manuscript left by Lady Ravenclaw from the library and became curious about that time a thousand years ago, and I very deliberately befriended Helena."

Dumbledore reassured him, "I, too, had deliberately befriended many famous wizards in my youth with a utilitarian purpose in mind."

"Thank you, Dumbledore." Felix said, "At the time, I also had the idea that, as Baron's friend, I hoped to ease Helena's resentment toward him."

"But as I got deeper into it, I found Helena to be a very fine lady, and it was a pleasure to chat with her, and I enjoyed it." Felix's voice trailed off.

Next, Felix cut back on his description of Helena, not wanting to mention her name in a pile of lies.

"... I realized that the Room of Requirement might be the chamber left by Ravenclaw, and I took her inside and met the memory left by Rowena Ravenclaw a thousand years ago."

Dumbledore's hand running through his silver beard stopped as he listened intently, not wanting to miss a word.

"... Lady Rowena Ravenclaw found the diadem, which she said contained a piece of an evil spirit, and magic said to have originated from a famous dark wizard of Ancient Greece, Herpo the Foul. "

Dumbledore's face became solemn, as he spits out a word: "Horcrux.".

"Yes, that magic, I thought about the diary and took it to Lady Ravenclaw. After her confirmation, the diary is also a Horcrux that belongs to the same person ."

"Very perceptive, Felix," Dumbledore said.

"Afterwards, Lady Ravenclaw used the vast magical power of Hogwarts to destroy it, and before the mission was completed, she recreated the diadem."

Felix finished telling the story.
