"Professor, you mean Harry Potter?"

Standing in the office, William asked for a moment.

Only Grindelwald and Voldemort can be called the Dark King. Grindelwald is not clear about it, but William knows that Voldemort wants to kill Harry with Avadasauer, but he dies.

As a third-rate time traveler, he doesn't even know the general plot, so why is he familiar with this kind of thing?

That's because everyone on earth (wizards) know it!

For Harry Potter, he was the only one who won the Avadasauri and did not die, which was a great achievement; for Voldemort, he was the only adult wizard who killed a baby but was killed, which was also an amazing achievement.

The two of them achieved each other, and their popularity was naturally not very high.

William also had speculations about why Harry was able to win Avadasauer's life without dying, but he did not expect it to be a prehistoric mystery.

"Professor, who used that magic?" William said curiously.

"Harry's mother Lily," Dumbledore said.

William squinted his eyes and thought. Since the other party knew such extraordinary magic, it also meant that he had been exposed to prehistoric mystery.

Lily, it’s amazing…wait, why is this name so familiar?

William remembered the memories he saw in the meditation pot, and he couldn't help asking: "Professor, Harry Potter's mother and Professor Snape, knew each other when he was a child?"

Dumbledore was silent for a moment and admitted directly: "I don't want to hide it, but as you can see, the two have known each other since childhood.

But William, I want you to promise that this matter cannot be brought up in front of anyone, remember, I am talking about anyone.”

Dumbledore's tone gradually became serious.

"It also includes Mr. Digory and Miss Qiu Zhang, and even Harry who will enroll next year, this is a big deal."

William nodded and quickly assured, "I will never tell anyone."

"You will know about how Lily gets that power later." Dumbledore changed the subject, "Let's continue talking about the previous issues."

Dumbledore took a sip of black tea and continued: "The ancient warlocks who were granted this power vowed to protect the prehistoric mysteries and ensure that they were not known to the outside world, because they believed that this power was too strong and too dangerous for the uncivilized masses."

“Same, only those who are qualified to be accepted can obtain prehistoric mystery.”

William raised his hand, blinked his eyes, and asked excitedly: "Professor, does this ring mean that I am a qualified person?"

Dumbledore glanced at William with a strange look, held back his smile and said, "Of course... not."

“…”

Dumbledore grabbed William's hand and looked at the ring with his blue eyes.

On the face of the ring is an eagle spreading its wings, and a book is decorated on the eagle's chest, which carved Runewen, who said "Time is the greatest enemy of mankind"; on the inner wall of the ring, it is carved: extraordinary wisdom is the greatest wealth of mankind.

"This eagle with books symbolizes prehistoric mysteries. This ring is actually the standard for sorcerers who receive the mysteries inheritance, and is equivalent to the wand of every wizard today."

Dumbledore slowly told the secret.

“As this Runevin said: the greatest enemy of mankind is time.

The prehistoric mystery is complex and cannot be studied without sufficient time. Therefore, the biggest function of this ring is to allow a person to spend a day repeatedly, have enough time, and constantly study the prehistoric mystery.

As for the words on the inner wall of the ring, Ravenclaw has a habit of graffiti, so I guess she added it herself."

William stared at the ring and was stunned.

According to Dumbledore, this ring is a magical item for the chosen one to study prehistoric mysteries.

Just auxiliary tools have such magical powers. William could not imagine how powerful the prehistoric mystery was.

"So, Ravenclaw is also a person qualified to learn prehistoric mystery?" William asked.

"It's not just her, but the four giants are all, otherwise why would four talented young people gather?"

Dumbledore crossed his hands and tapped his index finger gently on his middle finger, giving off a rhythmic rhythm.

"Then why did they choose to build Hogwarts?"

"William, for thousands of years, there is a saying that prehistoric mysteries were passed down from generation to generation in the early Egyptian mystical schools.

The four giants studied there, and then suddenly left for some reason and came to the castle in Slytherin's home. They imitated the mysterious Egyptian school and established the Hogwarts Magic Academy."

“After leaving the Egyptian Mysterious School, the eligibility was disqualified and the ring had to be reclaimed.

But Ravenclaw liked this ring, she was a wizard who was reluctant to be bound.

So, when she left Egypt, she used some powerful magic to forcibly undo the contract between the ring and the Egyptian Mysterious School, took the ring away, and became the owner of the ring."

William was stunned, such a domineering woman.

"After Ravenclaw disappeared, the ring existed as the door knocker of Ravenclaw's common room, leaving it to her successor."

"successor?"

"Yes," Dumbledore nodded, "only a real Ravenclaw can use this bronze ring.

Perhaps you have heard from the premier that a student once read all the books in the Ravenclaw common room in one day.

It wasn't fake, he got the ring briefly."

"Professor, I have another question," William said. "According to your words, I am not the person chosen, nor the real owner of this ring. Does it mean that I cannot freely end the time loop?"

A hint of admiration flashed in Dumbledore's eyes: "Yes, William, you're just a user and can't decide when to end the time loop, but this ring can."

Dumbledore gently stroked the eagle: "Ravenclaw's door knocker will ask questions and determine whether students can enter and exit the lounge based on the answer, which means that the ring is infused with Ravenclaw's thoughts."

"Like a branch hat?"

"That's right."

“How do you end this cycle?”

Dumbledore said happily: "Although we are not a ring and don't know what it thinks, we can still make guesses through clues..."

Following Dumbledore's reminder, William thought carefully.

"Before I'm going to think about how to save Hagrid, Robert, and catch Professor Tywin."

Dumbledore nodded and affirmed: "Then when you have the ability to save these people and have a complete insight into the whole incident, you will leave the cycle."
