Connor's Hogwarts

"You're back."

"I'm back."

"You came back quickly."

"You're not slow either."

"?"

"Ahem. It's nothing. Just kidding. Professor Dumbledore, you don't seem worried about me at all. Are you so sure that I can come back safely?"

In the principal's office, Connor and Dumbledore sat opposite each other. They were still in the same position, with the same snacks and juice. The slight change was that there was soothing background music in the office.

It seems that our principal is enjoying his senior life very much

"Of course I have full confidence in you. Aren't you back in one piece now? And you've brought back a cute little friend." Dumbledore showed a kind smile to Angel, who was sitting next to Connor and huddled together:

"Okay, Connor, now come and tell me your treasure hunting story in detail. I can't wait to hear about your wonderful experience."

"Ahem, it's just an ordinary adventure story."

"Finally, based on the complete staircase change pattern recorded by Conan, I deduced the secret language of the last staircase and found the spiral staircase leaving the hanging garden. It was a staircase composed of very complex space magic. Walking on it I can even intuitively feel the magnificence of space magic from above, and the spiral staircase finally leads to the Room of Requirement! I think the space-changing ability of the Room of Requirement is most likely the work of Ms. Ravenclaw."

"In the end, Helena chose to stay for some unknown reason, and I left with Saber and Angel. This is probably what happened." The version Connor said this time did not contain any exaggeration, but it was better than just now. It takes less time to talk.

Connor took a sip of juice and looked up to find Dumbledore staring straight at Angel, as if looking at some rare treasure.

"Connor, are you saying that this child, Miss Angel, has inherited all the magical knowledge of Ravenclaw?"

Connor nodded: "I instilled all the knowledge in the mark given to me by Ravenclaw into Angel. Ms. Ravenclaw did say at the time that this was all her knowledge inheritance."

"So what kind of knowledge does this have?"

"Well" Connor scratched his head: "It's hard to explain clearly. In fact, I haven't even looked at it. Angel should know better than me."

"Hmm, that's right! I know everything!" Angel nodded cutely and replied cutely.

Dumbledore's half-moon glasses had a strange reflection: "Oh? So... is there a process for making magic scrolls?"

Connor gestured to Angel, and Angel responded obediently: "Yes."

"Is there any way to apply ancient Egyptian writing?"

"Yep."

Dumbledore began tapping his fingers on the table incessantly: "Is there any heraldic record of goblin magic?"

"Yep."

Connor felt that Dumbledore's breath had become a little thicker: "How many records are there about soul magic?"

"Well, I don't know much about this. I only know some contract magic."

Connor quickly added: "Ms. Ravenclaw has mentioned that she is not good at soul magic."

Dumbledore nodded, as if he had calmed down a little, and then he asked several more questions, which should all be about the so-called "lost magic". As a result, Angel gave an affirmative answer. Only then did Connor realize How valuable is the inheritance of this knowledge?

It was so precious that even Dumbledore couldn't sit still in the end. He stood up and paced back and forth in the room: "Last question, Ms. Ravenclaw is best at space magic. To what extent is it specific? What about space magic? Is it an ancient teleportation array? Or is it opening up a complete different space?"

Angel tilted her head and said: "Grandpa, these two you mentioned are relatively simple space magic, and the more complicated one. Hmm, I can not only design the [Boundary Membrane], but also make the [Clock of Time]! "

Connor scratched his head and asked: "[Clock of Time]? What is that?"

"Hmm." Angel rolled her eyes and said, "It's a magic prop that can travel to a designated parallel space world. It's so complicated!"

Connor didn't understand yet, but Dumbledore was so shocked that he lost his temper: "Time turner?! You mean you can also make a time turner!!???"

"Eh?" Connor Zhanger was confused, time turner? That thing like a bug in the movie? Really? But isn’t that time magic? What does space magic have to do with it?

"What is a time turner?" Angel asked innocently.

Dumbledore took it out with his backhand, and something like a pocket watch appeared in his hand. He handed the pocket watch to Angel and asked, "Is this the [Clock of Time] you mentioned?"

Angel took it, looked at it, nodded and said, "That's right, this is a simple [Clock of Time], so now it's called a time converter."

Dumbledore gasped. Connor had never seen such a shocked emotion on his face, but Connor was no less shocked than him.

"Wait a minute. Can anyone explain it to me? Professor Dumbledore, what is a time turner? Shouldn't it be a time magic item?"

Angel tilted her head: "Dad, the [Clock of Time] is actually a space magic prop. There are very few magic related to time."

Connor was so frightened that he wanted to run to look up the mark now. Did it actually contain so much exciting knowledge? Of course, now was not the time to read a book. Connor looked at Dumbledore, hoping that the old man could explain it to him.

Dumbledore was obviously still immersed in shock. When he noticed Connor's gaze, he said leisurely: "Yes, the time turner is indeed space magic. Connor, do you remember what I told you: [In the past Can’t the facts of what happened be changed?”

Connor nodded in confusion: "It seems... yes, the time turner."

"The time turner cannot change the past or modify history. You must remember this." Dumbledore returned to his seat and sat down to drink water. He organized his words and said: "There is no one in this world who can modify history at will." Magic, but our time-turner can actually do it [go back in time]."

"Actually, the principle of the time converter is not complicated, as long as you understand one concept - [parallel space]. We assume that around the space where we exist, there are countless worlds exactly like ours, just like in the same world There are countless parallel lines in the long river of time, and the worlds develop according to completely consistent trajectories without interfering with each other. We call these worlds with exactly the same trajectories [parallel spaces]."

Connor was a little suspicious that he had entered the wrong set? This style of painting is wrong. Isn’t this a magical world? Why did quantum mechanics suddenly come up? Even parallel universes appear? Or is it that science and magic actually lead to the same goal through different paths?

Seeing Dumbledore stop and look at him, probably waiting for him to digest this information, but as a person from the future, Connor still knows a little about this stuff, so he quickly replied: "Ah, okay. I think I understand parallel space." Professor, please continue."

Dumbledore nodded. As a student, he has always been smart, so it was not surprising that he understood: "The function of the time turner is not to take you back to the past time and space, but to bring you to the adjacent time through magic and precise positioning." Go to the [parallel space], and this process is irreversible, let me give you an example."

Dumbledore put the time turner around his neck and began to turn the time on it

"It's eight forty now. Let me think about it. I came back to the office about an hour ago."

As soon as Dumbledore finished speaking, he suddenly disappeared from Connor's eyes!

"Ehhhhh!!?"

But before Connor could react, Dumbledore suddenly walked in from the door of the principal's office.

Connor looked at the principal and then at his chair. He was surprised and said from ear to ear: "Ah this."

Dumbledore walked around Connor and sat back on the chair again, and said, "Connor, I have been standing outside the door for an hour just now. Do you understand this magic now?"

"." Connor shook his head numbly.

Dumbledore touched his beard and said: "Actually, the me standing in front of you is no longer the original [me]. I come from another [parallel space] with exactly the same trajectory, but because everything about us is different." are the same, so there is actually no difference between me and [me].”

"Suppose I am Dumbledore A from world α, our world is world β, I am Dumbledore B who just talked to you, and there is another Dumbledore C in the other world γ where I B just went. So what just happened is that B in world β went to world γ an hour ago, C went to my world α, and I came to your world β.”

"The result is that the combination that was supposed to be Aα, Bβ, and Cγ turned into Cα, Aβ, and Bγ after using the time converter."

"I used a time turner to come to this world an hour ago, and just now [I] used a time turner to go to another world an hour ago, and so on. I don't know how many of these are exactly the same. The 'I' in the world has changed in time, but eventually there will be a world where the 'I' will go to my original world, and then there will be almost no change between the 'I' in these parallel worlds and the world. It creates a closed loop, but - we steal an hour of time at the same time.”

"This is the working principle of the time converter. Although from the results point of view, these [parallel spaces] have not changed in any way, in fact, the me sitting in front of you is no longer the original [me]."

"So the time converter is strictly a space magic item, not a time magic item."
