After leaving the principal's office, he had already arrived at noon. He went to the grand auditorium for lunch and then resumed normal classes in the afternoon. Then, he used the time-traveler again to return to noon and practiced magic in the remote enchanted forest far away from the castle.

    Those Dementors could hold back the young witches and wizards, but not him.

    And he left the school to practice magic, which was with Dumbledore's permission and not against the school rules.

    If the Dementors dared to stop him, he would kill them and the Ministry of Magic wouldn't have a say.

    He practiced all kinds of magic until evening, returned to Hogwarts for dinner, and then spent the rest of his time reading magic books in his dormitory.

    At night, he usually didn't read in the common room because that was when all the young witches and wizards from different grades gathered to tell tall tales and have fun. He couldn't concentrate on reading there, and he would become the focus of attention for everyone.

    Unfortunately, being too outstanding is also a burden.

    At ten o'clock, he turned the time-traveler once again, returning to five in the afternoon, and continued to practice magic in the Forbidden Forest.

    Around nine thirty, he began to return to the castle. On his way past the greenhouse, he plucked a leaf from a Mandrake plant and put it in his mouth. Today was a full moon.

    As he entered the castle to return to his Slytherin dormitory, he unexpectedly ran into the Weasley twins in the great hall.

    originally george had no intention to pay attention, the Weasley twins breaking the rules to roam around at night was common, and he wasn't a teacher, so there was no need to worry about it.

    But this time, he stopped in his tracks.

    Because this time, the Weasley brothers were holding a map, and the map even exposed his location.

    "Oh, it's George, George is right around here! He's over there!"

    The Weasley brothers suddenly turned their heads towards George, who was hidden by an invisibility charm.

    Seeing that he had been discovered, George broke the invisibility charm himself and whispered with a smile:

    "Good evening, it's against the rules for you two to be out and about at this hour."

    "We breaking the rules is normal, but I didn't expect George you would also break the rules to hang out either, it seems we are all the same kind of people."

    The Weasley twins chuckled and approached George, expressing their admiration for his nocturnal wanderings.

    George, on the other hand, looked down at the interactive map held by the Weasley twins.

    "What's this, it can actually reveal my invisibility charm?"

    Of course, he knew what it was. It was the Looper's Map, a magical artifact created by the four people - Remus Lupin, Peter Pettigrew, Sirius Black, and James Potter - who jointly used alchemy to make it.

    It not only shows all the secret passages inside the castle that have been explored by the four of them using Animagi transformations, but also clearly displays the position changes of every wizard who has appeared in the castle.

    At the same time, it was also given some wisdom by the animating spell and would mock their old rival Snape.

    The Looper's Map showed that the four indeed had extraordinary magical talent in the past.

    It's worth noting that while the Looper's Map was primarily created as a prank, it actually used many advanced magical incantations and is considered one of the top-tier magical artifacts.

    Hogwarts Castle is no ordinary place, filled with all kinds of magical wonders, but in such a place, the Looper's Map can show the location of any wizard.

    And not only that, it's not fixed to track a specific wizard; it can track the locations of all wizards within the castle, even the animals like cats.

    Even Dumbledore isn't an exception to this.

    If used for defense, any invaders within the map's range can be clearly shown with their names and locations, which is way more powerful than the modern surveillance systems spread all over.

    Even in places full of modern surveillance, you can still be discovered by transforming into a mosquito and going invisible.

    However, on the Looper's Map, there is no place to hide.

    So how could he have such a good thing?

    He doesn't need the Looper's Map to keep tabs on the wizardly goings-on in Hogwarts Castle. What he wants is to study the Looper's Map to deduce the magic spells and alchemy techniques it contains.

    In other worlds, he can make similar magical artifacts.

    "This is a good thing."

    The Weasley twins tapped the sheepskin paper in their hands with their wands:

    "I solemnly pledge that I won't do any good."

    In an instant, thin ink lines spread out like a spider web from the tips of the wands of the two Weasley brothers, connecting each other and spreading across every corner of the sheepskin paper.

    Then a line of green calligraphic words appeared on the sheepskin paper:

    "Ladies and gentlemen, the creators of magical pranks, presenting the Looper's Map!"

    After the green letters disappeared, a map covered with many small black dots appeared in George's eyes.

    "Amazing, isn't it? We found this in Professor Feary's drawer when we were in first year. We threw a big dung ball down the corridor."

    The two brothers excitedly told George about their heroic deeds of outsmarting Professor Feary in first year.

    But halfway through their tale, they suddenly stopped because they noticed that Professor Feary and his cat had patrolled to the second floor, and they would be in the great hall any moment now. Staying there any longer risked being caught.

    "Let's find a secret passage and hide for a bit. We'll tell you later."

    "No need for such troubles."

    George reached out and grabbed the Weasley twins, instantly taking them into the mirror world along with him.

    "Wow, what spell is this? I've never heard of it before."

    The Weasley twins watched the mirror world, completely different from Hogwarts, and then saw Professor Feary appear in the mirror in front of them. However, he couldn't see them at all.

    This practically had their eyes gleaming with excitement.

    If they could learn this spell, their level of pranks would definitely be greatly improved.

    Imagine how much fun it would be to see Professor Feary's furious expression after their prank, but knowing that they won't be discovered.

    They could even use a magical camera to capture the moment of Professor Feary's fury.

    "This is the Hungarian Mirror World, which I invented myself."

    Once Professor Feary had left, George took the twins back to the common room in the normal world.

    After believing the lies he had concocted, Dumbledore warned him not to tell anyone else to prevent any unnecessary turmoil.

    So when he performs all kinds of magic that are not from this world, he still says they are new magic he created.

    "Want to learn? I can teach you."

    George's tone was full of temptation.

    The Weasley twins nodded eagerly upon hearing this.

    "We want to learn!"

    "All right, but there's a condition; I'll trade for the Looper's Map you have."

    George smiled.
