Cardcaptor at Hogwarts

"Did this guy have this habit of teleporting when he doesn't walk properly?"

Merlin returned to his human form and scratched his head. What should he do? If Adam only used teleportation to move around in such a tightly protected place, wouldn't he be unable to contact the other party at all?

After all, these protections are also developed based on shields. Even if they are in a passive operating state without anyone in charge, Merlin can still think of ways to break them, but it is extremely difficult to get around them.

The problem is that he was entrusted by Merlin in this world to help Adam manage the human alliance. He can't force his way in now, can he?

Hmm... Is there any way to attract the other person's attention without any malicious intent?

Got it!

With a fist strike, a light bulb lit up on Merlin's head, and then Merlin's figure disappeared directly from the spot.

A breeze blew by, and a beautiful flower slowly bloomed on the green grass outside Hogwarts.

On the other side, Adam took the tour group to visit the stained windows of the Four Giants, passed through the center of the castle and went up the stairs:

"It's surrounded by classrooms for various disciplines. In addition, there are professors' offices corresponding to the disciplines. For example, here is Charms, and over there is Transfiguration..."

"Where are the Potions classroom and offices?"

A young wizard wondered, realizing that Adam had missed this subject.

The identity of this person is also worth mentioning. His surname is Peverell. He is the ancestor of the three brothers in the Deathly Hallows. He is also a wizard who is very accomplished in potions... To be precise, it is actually poison and correspondence. He has profound knowledge in antidote.

"The Potions classroom is on the underground floor, Mr. Peverell, because many potion materials need to be kept away from light, and to avoid interference from light during the process of brewing the potion."

Hearing Adam's explanation, Peverell nodded suddenly.

After explaining, Adam looked at everyone:

"The next thing I will take you to is the Hogwarts School History Exhibition Hall and Museum. There are many commemorative items from the founding of Hogwarts to this day. In addition, there are various memorable items from Hogwarts. An archive of the development and changes of things, including flying broomsticks..."

While they were talking, a group of translucent, pearl-like milky white people passed through the wall, talking and laughing all the way through the stairs not far below them.

Ravenclaw walked to the stair railing with excitement and looked down.

"Ms. Gray is a loner and doesn't usually hang out with other ghosts."

Adam stepped forward and comforted him, then looked at the one who smiled the brightest among the ghosts:

"Fat Friar, have you seen Ms. Grey?"

"Oh! Professor Reed."

When the ghosts realized that it was Adam, they quickly said hello, and then communicated for a while. Finally, the fat monk looked at Adam and said:

"About the second period in the morning, the Gray Lady saw Ms. Gray on the edge of the corridor on the second floor, but now she doesn't know where she is."

"Thanks."

Nodding towards the fat monk, Adam looked at Ravenclaw:

"So... the location of the corridors of Hogwarts has not changed, and the school history exhibition hall is next to the principal's office on the eighth floor. The principal's office is your former conference room."

"Thank you, I will meet you there later."

Ravenclaw nodded to Adam, picked up his skirt and ran downstairs.

"So……"

After Ravenclaw left in a hurry, Adam stretched his hand upstairs and said:

"Everyone, let's get going, shall we?"

Most of the wizards who came here had studied at Hogwarts, so they didn't show any impatience along the way. Instead, they were very curious about the changes in Hogwarts after them.

On the way upstairs, some wizards would even suggest changing the route slightly, and then find some traces of their past at the destination.

"Oh, there are no more..."

A wizard looked at the classroom door in front of him and sighed.

"What did you leave behind?"

The wizard beside him asked curiously, and Adam also looked at him.

"I still remember when I was practicing magic spells, I accidentally made a big hole in the door..."

Adam:…

It’s a ghost that these traces can remain until now!

Oh no, there really is a ghost in Hogwarts...

"I saw that some classrooms that were once used were later abandoned. I remembered that the classroom at that time has not been used again since then. If it continues to be like this, maybe the hole can still be left... …”

The wizard was obviously a little disappointed, but otherwise he left no identifiable traces at Hogwarts.

Seeing that everyone could find some traces of themselves in history, but he was unable to participate, it was really...for a moment, the wizard's eyes even became a little wet.

Seeing how pitiful he was, Adam thought for a while and said:

"Although the door has been replaced, the original door may still be found."

Hearing this, the wizards around him couldn't help but look at Adam in surprise.

Adam wouldn't travel through time to find a door panel for such a trivial matter, would he?

If that's the case, then they also have something they want to get back...who wouldn't cry!

Seeing that they were overthinking, Adam could only explain:

"In Hogwarts, there is a place where junk is accumulated, and almost all discarded things will be moved there..."

"Come and go to the house?"

Standing in front of the Room of Requirement, several wizards in the team couldn't help but say that they had obviously found this magical room in Hogwarts.

"Yes, this room is also called the Room of Requirement. As long as you concentrate on thinking about the place you need and walk through the road in front three times, it will appear."

Adam asked everyone to make way for that place, because too many people would affect the appearance of the Room of Requirement:

"The room I'm talking about is a room for hiding items. Just recite this in your mind."

The wizard did it, and a smooth door appeared on the wall when he walked through it for the third time.

"It's amazing... Is this the work of Ravenclaw?"

Gryffindor looked at this scene with surprise. It turned out that the future Hogwarts became so interesting. He suddenly had the idea of ​​exploring Hogwarts. What should he do?

Although most of the castle is still the same as when he built it, it's more interesting this way, isn't it?

"It's possible. Many people who know about the existence of this room think so... Speaking of which, after Ravenclaw's diadem was made into a Horcrux, it was hidden here."

Slytherin's feet suddenly stumbled, almost tripped by a box, and then glared at Adam.

You kid is plotting against me again!

Luckily, Ravenclaw is not here now.

"Door panels are flying!"

Just then, a spell with obvious excitement and expectation came from the front.

Adam was stunned, and then he heard the sound of objects colliding from all directions.

Wait, the Room of Requirement...How many door panels are there? !

And obviously, Adam is not the only wizard who discovered this loophole.

"Armor protection!!!"xN
