After Adrian's careful explanation, Rolf got a general understanding of the function of this disc, which has a nice name, called Remembrance of the Moon God.

As its name suggests, this inconspicuous disc was once an artifact, but because it was too old and the damage was severe, its efficacy was greatly reduced, and the power of the artifact was no longer restored.

It is said that this treasure is an artifact given by the moon god to his followers, the centaurs, and possesses the power of the law of time.

Is it because of the alternation of the sun and the moon?

Its effect is very different from that of time-shifting magic, which is not only restrictive, but also leaves a lot of sequelae, and the slightest carelessness can cause an unimaginable butterfly effect.

And this artifact of the moon god can surpass the long river of time, of course, this means that the artifact is in a complete state.

And after the damage of the artifact, if you want to travel through time, you have to pay for your own magic, that is, as long as your magic is deep enough, there is no problem at all to travel to the period of the Big Four.

If you want to change history, you need to sacrifice to the moon god, and depending on what you sacrifice, you can determine the limit of how much you can change history.

But...... Or is it the same question, the moon god has disappeared, so to whom is this sacrifice sacrificed?

Rolf was about to say goodbye to Adrian and go back to Hogwarts Castle to deal with Old Deng, when Adrian continued, "You still can't learn healing magic?"

Only then did he realize that it had been a long time since he had come to Li Chrissy to learn healing magic, "The main reason is that we have been taking too many classes lately, especially with the addition of a class on Occlumency, and there is no time left." ”

There's no time for, Rolf is now obsessed with contemplation and can't extricate himself, how can he have time to learn any healing magic?

As Rolf walked down the path from the Forbidden Forest to Hogwarts Castle, still thinking about Lockhart, he was a little confused right now.

Lockhart turned out to be a sculpture, not a human at all, so how is the sculpture used, and what is its purpose?

It seems that I still have to find a chance to talk to that woman, but I don't know what Lockhart did to her, and I feel like why is she a little stupid now?

As soon as he entered the castle gate, he saw Professor McGonagall standing in the doorway waiting for him, and when he saw Rolf approaching, he said:

"Mr. Scamander, Professor Dumbledore is waiting for you. Professor McGonagall's hair was still in a meticulous bun, and with a serious expression, he always felt like a mouse meeting a cat.

Rolf nodded, and followed Professor McGonagall to the school doctor's office.

"What? Lockhart? Who are you? Where am I?" they could hear exclamations coming from inside as they approached the school infirmary.

When he pushed the door in, he saw Madam Pomfrey struggling to restrain the mysterious woman, while Luna watched with some curiosity and interest.

Professor Dumbledore was standing in front of the bed, as if asking something, but looking at the insane woman, he seemed a little helpless.

At that moment, Professor McGonagall knocked on the door and signaled for the room to come.

Professor Dumbledore looked back at Rolfe and nodded at him slightly, seeing that he couldn't laugh, it seemed that this woman was very difficult.

Professor Dumbledore walked out the door, and Rolf immediately followed, out of the door to the school infirmary.

"Have you already returned the item to the Centaur tribe?" Professor Dumbledore asked.

Rolf scratched his head, and then said embarrassedly: "No, Adrian said that since the prop is in my hands, it belongs to me, and he will not accept my return." ”

He followed Dumbledore's words, and as for the fact that it was an artifact, of course he chose to hide it.

Dumbledore nodded, "Since it's yours, you can keep it, but I hope you don't use that item indiscriminately, and I think you know that all things related to time are not so simple." ”

Rolf nodded approvingly, indicating that he knew, and then asked, "Professor, who is that woman, and why is she at Hogwarts?"

Professor Dumbledore glanced at the school infirmary, then looked around at no one before saying, "It was a Ravenclaw graduate, but she's completely amnesiac now, and she doesn't remember anything." ”

"Amnesia? impossible, she remembers the spell used by the disc, how could it be amnesia?"

There is another sentence that Rolfe didn't say, Dumbledore, as a master of regents, should be easy to solve the small problem of whether he has amnesia or not, right?

And although the Oblivion Charm can erase her memories, Lockhart can't make all her memories disappear with just one Oblivion Charm, right?

Rolf looked at Professor Dumbledore suspiciously, but when he saw the professor blink slightly meaningfully, he knew what was going on.

He tried to empty his mind so that he didn't think about anything, because Dumbledore was probably still working on his deception.

He regretted that he hadn't studied Occlumency properly, and he was really trembling in the face of Dumbledore, the Master of Mind Taking.

"Alright, Mr. Scamander, I won't check my students' memories at random, don't be so nervous, now you can go back and get some rest, Miss Lovegood has told me everything you have been through. ”

Seeing Dumbledore's somewhat smiling expression, Rolfe breathed a sigh of relief, but he still didn't dare to think nonsense, and tried to keep it empty.

Rolf felt the need to talk to the woman as soon as possible, wondering if she remembered anything about the sculpture.

Just as he was thinking about the sculpture, Dumbledore suddenly said, "By the way, Mr. Scamander, I wonder if you would mind lending me that sculpture for a few days?"

Rolf is not good, and he said that he would not casually probe the memories of the students, so what is this for!!

I believe you're a ghost! Bad old man, very bad!

Wait, will he find out if I complain about him? Tsk, I'm so hard, Occlumency has to have a name right away!

He nodded helplessly, and then resigned himself to reach out and take out the sculpture that had been placed in the Traceless Stretch Bag, and handed it to Professor Dumbledore beside him.

"Don't worry, I'll give it back to you after I've researched it, and you don't need to talk to her, I'll tell you when I make progress." With that, Professor Dumbledore re-entered the school infirmary with the sculpture.
