After the transformation class ended during lunchtime, it was already noon.

    "George, let's go to the auditorium for lunch together?"

    A Slytherin witch from the same year level extended an invitation to George for lunch, and George smiled and declined:

    "No, I need to go ask Snape Professor for some magic questions."

    With his current popularity, he often receives various invitations from little witches in the school.

    This is normal, teenagers are at the age of first opening their hearts, and even in his previous life, at this age, he had a crush on someone, but it was not as bold and courageous as these little witches.

    Therefore, in order not to delay these little witches, not to let them have unrealistic fantasies, George always rejects these invitations very firmly.

    If you know that someone likes you but you clearly do not like them in return, the best approach is not to worry about their hurt feelings and drag it out; instead, to reject them firmly and decisively is the most appropriate way to handle the situation.

    It is unrealistic for children at this age to say that they are very firm about their feelings. After being rejected, in a few months, they will naturally fall in love with someone else.

    But sometimes, if they encounter little witches with thicker skin, the rejection won't work.

    For example, if he claims to have something to do, she will ask what it is, and then follow him around, insisting on accompanying him. It's a classic case of relentless pestering.

    At this time, Professor Snape is quite helpful. As long as one says they need to consult with Professor Snape about magic, most little witches would be afraid to follow him.

    Not only the young wizards from other houses, but even the Slytherin students fear their headmaster deeply in their hearts.

    "Oh, well, then never mind."

    As expected, when George said he was going to ask Professor Snape about magic, the expressions of the little witches changed immediately.

    She was criticized by Professor Snape half to death in her potion class yesterday because she put the wrong materials. Now she shakes when she sees Professor Snape.

    Since George's voice was a bit loud, the other little witches who were also trying to invite George to eat with them heard him, and immediately stopped walking towards him.

    George put away his spellbook, turned and left the classroom, then found a deserted place and turned the time-turner back to five hours ago.

    When turning the time-turner, it is important to find a place with fewer people and be certain that you were not there five hours ago.

    Otherwise, if someone suddenly appears in the past, it might startle them. And if the past version of oneself encounters the current version, it could cause temporal confusion, which might result in significant harm to oneself and even involve others.

    After turning the time-turner five times, George felt as if the scene around him was rapidly reversing like a slideshow with countless speed boosts. In the blink of an eye, he returned to five hours ago.

    "Magical time magic!"

    Although he has experienced it many times, George still can't help but exclaim each time.

    Unfortunately, the difficulty of the time magic is very great, even if he consults with Dumbledore, it's hard for him to get a grasp of it in a short time.

    The main problem is that the available time magic is too limited, and related knowledge is not systematic enough. Even Dumbledore was not particularly good at this aspect, and many times he had to rely on his own understanding.

    He also thought about whether he could find some time magic references from other worlds, so that by comparing them, it might reduce the learning difficulty a lot.

    But that is clearly not an easy task.

    Although there is the Time Gem in the Marvel World, and Gualon is a master of time magic, George does not want to interact with him at present.

    He has too many secrets, and until his strength can match that of Gualon, he does not want to have too much entanglement with her.

    Behind Gualon is the Supreme One, Eternity. These existences are far beyond what he can imagine at present.

    In the world of the apprentice of magician, there are no records of time magic in Merlin's Book or Moragana's Book. This world seems to have no research on time magic at all.

    In the Fairy Tail world, he did find some clues about time magic, but it had been listed as the lost magic known as the Arc of Time.

    What is a lost magic? It's a magic that has disappeared. Therefore, there is none now.

    In Academy City, he had just started to learn about magician. In Shelly's memories, there were no messages about time magic.

    He just doesn't know if there is a book about time magic in the collection of one hundred and thirty thousand books in Entics' mind.

    In Middle-earth, he had never heard Finrod say that they would have time magic.

    So regarding time magic, he can only put it aside for now. At present, he mainly focuses on learning alchemy, which can be said to be just at the beginning stage.

    Hogwarts doesn't have a dedicated class for alchemy, but that's fine. Hogwarts has an alchemy master who is second only to Nicolas Flamel, and that is - Dumbledore.

    Dumbledore is not only extremely skilled in transformation magic and black magic defense, but also has many other achievements. One of them is alchemy, and he knows most of the alchemical skills in the world.

    He also invented the extinguisher that can turn off the muggle electric lights.

    Don't underestimate the small extinguisher; the magical and alchemical knowledge it contains is by no means negligible.

    Muggle electric lights are not candles or oil lamps, but devices for lighting up.

    Dumbledore's extinguisher, when opened, does not break the electric light, but it can absorb its brightness. No matter how much electricity is passed through or operated on, the brightness of the electric light will not appear again unless the extinguisher returns the light.

    Upon further thought, this is an embodiment of a rule.

    If the function of the extinguisher is amplified, it can suppress all light, take away all light, and even take away the light of the sun, plunging the whole world into darkness.

    Therefore, Dumbledore's alchemy is undoubtedly the most advanced in the entire wizarding world.

    Today, he plans to find Dumbledore and start learning about the creation of door keys.

    Because he thinks that this is the most practical magical artifact for him across all worlds right now.

    His Phantom Repository can only teleport him to places he has been before, and places he hasn't been cannot be reached by flying, and there are also distance restrictions. It's not easy to bring people along.

    Although he can put people in a space box, sometimes he doesn't want others to know that he has a space box.

    The door key is different; it's like a space portal. Once the location is set, it can transmit over long distances, and it can also transmit in large quantities.

    He doesn't even need to be present for it, he can hand it over to others and use the door key for transmission.

    Two people with two door keys, no matter where one of them runs, the other can appear through the door key.

    In the Marvel Universe, he could throw one in each city, so he could appear instantly in any city on Earth in the future.

    In Middle-earth, he could use the door keys to transport a large number of Elven soldiers, providing support in various battlefields and achieving a surround effect, as well as being used for surprise attacks and ambushes.
