HP: The opening tarot card is used as a Horcrux

The four founders all made different contributions to the establishment of Hogwarts.

Among them, there are rumors that the Hogwarts castle and the surrounding land were contributed by Slytherin.

Of the other three founders, Ms. Hufflepuff was responsible for the initial establishment of the Hogwarts system and brought a large number of house elves with her.

Gryffindor's credit is to guard Hogwarts - the unconventional form of the wizarding school was rejected and hated by many pure-blood families and wizarding schools in that era. The other three founders were all resident in the school, guarding school, and Gryffindor chose to leave the school and take the initiative to defeat all enemies who snooped on Hogwarts.

The last Ravenclaw, the wisest lady's contribution, had been rumored to have founded the school's library.

But wizards who know the Room of Requirement all know that this lady also has a specialty that is unknown to the outside world - alchemy.

That's right, all the magic and alchemy facilities within Hogwarts were built by Ravenclaw ladies.

Therefore, isn’t it easy to guess that the core of Hogwarts is hidden inside the Room of Requirement?

The space where Dumbledore and Grindelwald were at this time was the core of Hogwarts. Faced with Dumbledore's concerns, Grindelwald first sighed:

"I have known about the Room of Requirement in Hogwarts for a long time. I have always wondered what its principle is! Is it [Transformation] or [Illusion] that can realize the request of the person? Now it seems that this It should be a combination of [Transformation] and [Memory Magic]."

"Collecting the magic power that all the wizards in Hogwarts emit every day, no wonder it can be built to the extent of the Room of Requirement."

"Opening the Room of Requirement definitely takes a lot of magic power. The lady's original idea should be to use waste to build herself a laboratory that meets all needs."

"But it is estimated that because of her hasty death and the deliberate concealment by future generations, there are very few wizards who know the Room of Requirement, and the number of times the Room of Requirement has been opened is also very small, so the corresponding consumption of magic power is also very low."

"That's why there is so much magic accumulated here."

Dumbledore frowned: "Gellert, what do you mean, it's too late to regret it now!"

"Albus, calm down, this matter is not that dangerous." Grindelwald, who understood that Dumbledore was worried about him, was very happy: "There is a lot of magic here and it is very strong, but our enemies are not those with magic. Master, these magic powers belong to everyone in Hogwarts, right!"

Dumbledore was stunned for a moment: "You mean you have a way to make it unable to control the magic here."

Grindelwald nodded: "But I can't do it alone. You will listen to my command later!"

"Okay!" After receiving the affirmative answer, Dumbledore no longer hesitated. He put his hand out of his arms, and then he took out a book with a quill floating on it.

"[The Pen of Acceptance and the Book of Admission]! So they are proof of recognition of the principal's identity!" Grindelwald couldn't stop being curious when he saw these two things.

When he was planning to integrate wizards from all over the world to rule Muggles, the biggest problem was how to solve the problem of little wizards being randomly born in Muggle families, and the first solution he thought of was these two legendary alchemical creations. .

He had long wanted to snatch these two things and study them to see if there was any way to directly expand the scope of influence of these two things to the entire world.

"The reason why these two things can cover the entire UK is because the magic accumulated in Hogwarts serves as a source of power for them. With the magic reserves of Hogwarts, it is no problem to expand to several surrounding countries, but the entire Europe Or even the whole world, that can’t be done.”

As expected of a soul mate, Dumbledore knew what Grindelwald was thinking without looking into his eyes.

After Dumbledore answered Grindelwald's questions, he slowly threw the two items towards the magical core of Hogwarts.

"Gellert, our enemy is coming!"

Following Dumbledore's reminder, after these two things came into contact with the magic core of Hogwarts, the entire Hogwarts Castle seemed to come alive and trembled - this was the magic core being opened with the authority of the principal. symbols of.

At this time, in the corridor of Hogwarts Castle, there is a special ghost who is throwing the collected garbage everywhere - yes, this ghost is Peeves, and it is rumored that it is a student accumulated by Hogwarts The elf condensed with rebellious emotions cannot leave Hogwarts and cannot be killed.

Because it is formed from the rebellious emotions of students, Peeves likes to play pranks the most and is most afraid of professors. He looks like a bad student.

But with the awakening of Hogwarts Castle and the opening of the magic core, Peeves, who was originally a bad student, changed instantly.

Its figure disappeared instantly, and then the next moment it appeared in front of Dumbledore and Grindelwald.

"Dumbledore... and Grindelwald?" Peeves' figure quickly stretched and lengthened, and soon turned into a faceless adult male.

Peeves' voice changed from its original appearance to an old male voice.

It had no facial features, but both Dumbledore and Grindelwald felt that they were being scrutinized by it.

"Dumbledore, you shouldn't be here, Grindelwald, you too - another mistake, damn it!"

The old guy who had awakened from Peeves in front of him quickly understood the current situation and immediately called on the magic accumulated in Hogwarts for thousands of years to launch an attack on Dumbledore and Grindelwald.

"Old guy, to Albus he is [Forgotten], to me he is [Avada Kedavra], it's a bit biased!"

This old guy's strength is indeed very strong due to the increase of the thousand-year magic power of Hogwarts, but his enemies are after all the two strongest wizards in the world, so it is impossible for him to hit with one blow, and both of them dodge. Said, Grindelwald can also taunt.

"Gellert, stop talking nonsense!"

"it is good!"

Dumbledore's voice of dissatisfaction directly interrupted Grindelwald's plan. He originally wanted to take the opportunity to talk more - however, the relationship with Dumbledore has finally recovered well recently, and Grindelwald was obviously unwilling to let go. The relationship between the two deteriorated because of the old guy in front of them, so Grindelwald took action immediately.

Under Dumbledore's surprised gaze, Grindelwald put away his wand, and then like an ancient wizard, he chanted a spell that Dumbledore couldn't hear.

Grindelwald's magic power formed ancient runes in the air. Then, before the old guy in front of him could react, these ancient runes directly entered his body, showing golden runes on his skin. .

"Gellert, this is..." Dumbledore was shocked. Is the gap between him and Grindelwald so big? Why couldn't he understand the operation just now?

"This is magic from the Eastern Continent. It was brought by a guy who recently cooperated with me." Grindelwald looked solemnly at the old man who was trapped by the magic just now and was temporarily unable to use the magic of Hogwarts. Guy, then he breathed a sigh of relief.

"It seems to have been successful - I don't know if this magic will work. If it doesn't, I'll be in trouble."

"But fortunately, it seems that the goddess of luck is favoring us."

"Albus, my magic power is now used on this old guy, so I can't do anything else. Now it's up to you. You have to mobilize all the magic power here, and then find a way to consume it all. Only This way, when the old guy breaks the seal, we can deal with him."

"Okay!" Dumbledore had many questions to ask, but it was obvious that now was not the time.

He quickly waved the Elder Wand and did as Grindelwald commanded.

How to consume a large amount of magic power? If other wizards answered, they would definitely choose to use attack spells to consume it.

But this was Dumbledore, how could he choose such a wasteful act.

This is a huge amount of magic, accumulated over thousands of years at Hogwarts, how can it be wasted.

So Dumbledore is seizing the time to use these magic powers to improve Hogwarts in all aspects.

What Dumbledore is best at is, of course, [Transfiguration] - so with the help of massive magic power, Dumbledore directly transformed some facilities in Hogwarts Castle, turning them into alchemy permanently. creation.

The first thing to change is the defense mechanism. It was originally just a stone statue that could be used as a warrior, but it was enchanted by Dumbledore in various ways. If Professor McGonagall still has the opportunity to use [Stone Dungeon Attack] like the original HP work after this time, then It's definitely a joyful scene.

Then there are the murals, the ban on the lounge, the self-cleaning and self-repairing of the walls, the magic shield on the outside of the castle, the hidden magic of the school...

"There is still some!" After Dumbledore completed the transformation of the castle, there was still a lot of magic left, so he had no choice but to make a disrespectful move towards the magical creatures in the Forbidden Forest, especially the centaurs - - He manipulated the remaining magic power to surround the entire Hogwarts Castle and the Forbidden Forest, and then arranged a comprehensive magic barrier that could be opened by the principal and vice-principal at any time.

"Epic level enhancement!" Grindelwald teased Dumbledore with a smile, and then he looked at the old guy who was still struggling.

"I can let you go now. I believe we will have a wonderful exchange!"

The golden runes on the old guy who possessed Peeves quickly disappeared one by one.

Then, just as the last rune disappeared and the old fellow began to stir, Grindelwald raised his wand.

"[Lock]!"
