Hogwarts: The Cat Wizard of the Moving Castle.

Things happened to Quirrell just as quickly as they came. He was not innocent. He chose to become Voldemort's supporter entirely of his own free will.

He is very smart, but wisdom and desire are like two gladiators who have been competing for a long time, sometimes winning or losing.

Under Voldemort's bewitchment, at that time, his desire obviously defeated his reason.

He chose a path of no return.

"Become a loyal believer of the Dark Lord and help him regain control of his kingdom. The one who will get the highest honor in the end will definitely be the one who helps the Dark Lord resurrect!"

At least, that's what Quirrell thought.

In the end, he died in the empty underground classroom.

His death was buried, and Dumbledore casually sent the Ministry back.

A few days later, in the principal's office.

"Can't you delete this course and teach it under a new cover? For example, the anti-black magic research course!"

Dumbledore shook his head: "It's completely useless, and it will only make the consequences of the curse more serious."

"For example, if I teach Defense Against the Dark Arts for one year this year and transfer to the Transfiguration course next year, what about the rotation of teachers?" Moon asked while teasing Fox.

Fox buried his head under his wings and ignored him.

"It's useless." Dumbledore couldn't help but laugh a little when he saw Fox's gesture.

"Want to try it? Curse!" he said.

Mu En thought for a moment, then nodded...

Dumbledore opened the side door of the office and walked with Moon on the eighth floor. He said a little tiredly: "I've never been good at cursing. If you want to take a look, that would be great."

"I'm not very good at curses either." Moon shook his head. Dumbledore always wanted to put a high hat on him, as if this could easily block him from doing things.

"Are you not good at cursing? I heard that Borgin has disappeared for a long time!" Dumbledore suddenly turned around and said, "I know it was you who did it. I can't think of anyone other than you!"

"Why are you so sure?" Mu En glanced at him.

"Because he has been tortured by the curse for decades, he repeatedly requested many famous wizards more than 20 years ago, hoping that someone could help him lift the curse.

But no one has ever been able to help him. The curse is very difficult, so difficult... Bo Jin no longer mentions it. Now perhaps few people remember him and his curse.

But you know, when people get old, they always like to look back on the past. "

"I just happened to know it." Mu En said.

"You have to give it a try, right?" As he said that, he took Mu En to an extremely remote small corridor on the eighth floor. Then he turned around and faced a wall.

There are many doors and walls in Hogwarts that like to exchange appearances. Some of them look like walls, but are actually doors that can be pushed open.

Some are doors, but when opened, there are impassable walls inside.

Obviously, this is the former.

Dumbledore walked towards the wall. Suddenly, under the sunshine outside the corridor window, ripples appeared on the wall, like running water.

Mu En also followed closely and followed in.

As soon as I entered it, a smell of dust filled my nose. It was obvious that this was a tower that no one cared about. In front of them, there was only a staircase that led directly upward.

"There are no house elves to clean here?!" Mu En waved his hand, and a strong wind swept through the entire empty tower, and the air suddenly became a little fresher.

"No entry or exit is allowed here." Dumbledore explained and took the lead to walk up the stairs.

On the stairs, there was a platform located on the half side of the tower. The sun shined in from the window. The two people stepped onto the platform, only to see that there was only a very old long table on the empty platform.

There is an ancient book on the table with a black dragon skin cover that has peeled off. Beside it sat a small silver inkwell, holding a long faded quill.

"Is this the Book of Access and the Pen of Acceptance?" Mu En walked closer and looked at the book and the quill carefully.

Dumbledore nodded and raised his hand slightly without touching the pages, and the pages began to turn slowly on their own.

His eyes swept over the names one after another, and he murmured: "This is the core of Hogwarts. The four founders worked together to create the Book of Admission and the Pen of Acceptance. Since the founding of the school, they have It exists and no one has ever touched it again.

Even Minerva, who comes here every year to register new students, would not touch it directly with her hands. "

As he spoke, the pages suddenly escaped Dumbledore's control. It turned the pages on its own and quickly locked on a page from 1992.

The pen of acceptance jumped out of the inkwell and added a new name.

"Luna Lovegood - February 1981, 2."

"I think this child may be the last of his year to be added to the books," said Dumbledore.

"Hmm..." Mu En responded casually: "There won't be any little wizard who accidentally breaks in here."

"Of course not, few people come here." Dumbledore said.

"Really?" Mu En looked at him with a half-smile: "Voldemort must have been here before, right under your nose.

He had taken hold of this pen and entered the depths of the magical fabric of Hogwarts, planting a curse on Defense Against the Dark Arts. "

Saying that, Moon spread his hands and looked at Dumbledore.

Dumbledore hesitated for a moment, then gently raised his fingertips and handed the pen of acceptance to Moon's hand.

Mu En held the quill and faced the Book of Access. In just a moment, he understood the general method of using it.

The next moment, the Book of Access began to turn its pages. However, no matter how much it was turned, the old and yellowed parchment on the left and right sides were still the same amount.

It seems that this book has infinite pages.

Then, the page suddenly stopped, a blank parchment appeared on the page, and Mu En slowly started writing.

The moment the silver ink touched the yellow paper, everything around it seemed to be stretched endlessly away.

In the blink of an eye, he came to the vast void. When he looked up, the stars were shining brightly.

Red, green, blue and yellow, four galaxies intertwined to form a beautiful picture.

He raised his hand slightly and pointed at the galaxy...

In the tower, the skylight outside the window fell on the two people who were still. Mu En slowly opened his eyes, opened his hand, and the pen of acceptance jumped back into the silver ink bottle.

He shook his head: "Riddle borrowed the power of blood to plant the seeds of curse deep in Hogwarts. Without the blood of the four founders, it would be difficult to enter the deep magic logic loop of the castle to clear it."

Mu En paused: "And this kind of curse involving fate..."

"You don't believe in fate, I know." Dumbledore smiled.

Mu En looked at him without saying a word, the fateful arguments of that day still vivid in her mind.

"It seems you have something you can't handle." Dumbledore turned around and said.

The two of them walked down the stairs.

"After all, this kind of troublesome work is very tiring, but I have other ways to solve it...it depends on whether you mind."
