Hogwarts: The Cat Wizard of the Moving Castle

"Is that okay?" Harry looked at Fred and George.

He had long heard about the love-hate relationship between the Weasley twins and the castle administrator Mr. Filch. Although he didn't know exactly what Fred and George's tricks were this time, it should be interesting to think about.

Maybe this is a good practical subject, but he is not one to sit still.

The Weasley twins looked at each other, shrugged and said, "If the captain said so."

"Then you can give it a try. Let's study it together. My name is Fred, Fred Weasley. You should know my brother, the other Weasley."

"I'm George."

Harry shook their hands and was about to introduce himself when he was interrupted.

"Of course, we know each other." Fred smiled.

Mu En looked at the three of them: "Okay, tell me what problems you encountered."

"Oh, yes." Fred ended his chatter and took out a mask from his clothes.

The mask is made of wood, white, and has not been carefully carved. It is just like a curved wooden board that barely fits the lines of the face with holes for the eyes, mouth and nose dug out.

The research and development cost of the magic potion was still too high for Fred and George. After being inspired by Mu En, they decided to use masks.

And this mask is made of fir trees. Among the woods suitable for transfiguration, ebony and fir have always been very prominent, and are even often used as wand bodies. Professor McGonagall's wand is made of fir.

At the same time, fir was cheaper, and Fred and George could afford it.

"After your inspiration last time, we successfully made the finished product."

"Then what is the problem you are encountering now?" Mu En looked at them curiously.

George smiled: "We will demonstrate it for you."

He turned to face everyone and clapped his hands slightly: "Everyone, everyone, I'm sorry to interrupt you for a moment. I wonder if I can take a minute of your time."

There are not many rules in this reading room. Most people regard it as relaxing here. The few learners looked up and saw Fred and George, so they didn't mind too much.

Their reputation outside of Slytherin is that the student body is always good and always lively.

"George, what tricks did you guys pull up again?" someone asked curiously.

"Of course!" George said, spreading his hands and pointing at Fred: "Next, I would like to introduce to you the advance version of the animal mask - the Lion King Mask."

Harry looked at Moon curiously, his eyes widening.

Mu En smiled back.

While George was introducing, he suddenly felt his hands heavy.

Fred put the mask in his hand and quickly took two steps back: "Yes, George will give you a demonstration next!"

"No, Fred, I know you like this thing very much, come on." George laughed.

Fred waved his hand quickly: "Don't refuse, George, everyone is looking forward to it."

The two pushed each other away twice more, and in the end George could only smile helplessly and nod, while there were boos below, urging them with a smile.

Harry could guarantee that he heard George mutter: "Damn, I didn't think of bringing Ron here."

Fred suppressed his laughter and reminded in a low voice: "Remember to hold back, don't let everyone have a bad first impression of our new invention."

"Fred, don't sleep too hard at night." George sneered and put on the mask decisively.

Harry asked in a low voice curiously: "Does this mask have any side effects?"

"It's nothing, it's just that your face will hurt and itch." Fred whispered, "It's probably like someone is pricking you with a needle."

Harry felt a little nervous and looked at George carefully.

After George put on the mask, the mask suddenly squirmed and wrapped George's entire head, like in a horror movie.

Then, the hairs on the mask began to grow out, and the entire face began to protrude forward.

When the little wizards saw this scene, they kept exclaiming, their faces full of anticipation.

At the same time, Harry also saw George's body shaking continuously. Obviously, the so-called pain and itching were not simple.

After a short time, George's entire head turned into a well-fitted lion's head, with thick mane draped over his shoulders, making him look extremely powerful.

"Merlin's beard!! George, can you still reply?" the wizard who just spoke shouted softly.

"Of course!" George's voice came from the lion's head.

But Harry found that the lion's mouth didn't move at all. This also made George's voice muffled.

"Is the problem we face now the dynamic capture of the facial features?" Harry said: "It's because the mask is transformed, not the actual head transformed into a lion."

"That's right." Fred nodded, looking at Harry with a somewhat surprised look.

"Oh, George, can you let me try?" Someone was so curious that he stepped forward.

"Sorry, the research is not complete yet. But we will work hard to get the finished product out on Halloween." George said quickly, and then he couldn't help it anymore and quickly took off the mask.

He put his hands behind his head and peeled off the mask as if tearing away skin. After the mask fell off his cheeks, it quickly returned to the appearance of a wooden mask.

And he rubbed his face carefully.

"This is our new work." Fred introduced.

"Can it be made into other shapes? For example, an eagle?" someone from Ravenclaw said.

"sure!"

"Can there be a shape that is beyond human imagination?" someone wondered.

"Anyone with a cat?"

The eyes of the three people and the cat immediately fell on the person who spoke, that was a Hufflepuff girl. After noticing the sight, her face turned red.

"Um...not...sir!" She explained quickly.

"I think this is a good proposal, as long as Mrs. Norris doesn't mind." Mu En smiled.

Mrs. Norris is Filch's old cat. She is thin and hairless, and her meowing is even more unpleasant. Many people in the castle hate her.

When the girl heard this, she understood that Mr. Jones didn't mind, and laughed awkwardly.

After arguing for a while, Fred and George turned around, handed the mask to Mu En, and told them the two problems they were facing now.

Unsynchronized expressions and tingling and itching of the face.

Mu En took a look. After his explanation last time, the Weasley brothers chose to use seal carving to make the mask.

In the past, the way they made magic items was by placing a spell on the item and then solidifying the spell. Or brew up special joke potions and turn them into candies.

The current seal cutting technique is actually equivalent to alchemy. You must know that this is not a mainstream discipline. George and Fred both worked hard to come up with such a finished product.

After Moon looked at it twice, he handed the mask to Harry: "Look at the spell inside."

The Weasley brothers' seal-carving skills were not very good, and the rough rune ravines were just displayed on the entire mask.

Harry took a look. There were many circuits that he couldn't quite understand, but he still vaguely recognized some.

"Hmm...I can only see the facial detection, flow wrapping, and solidification runes inside the mask. The one on the outside of the mask should be the directional deformation rune in the shape of a lion."

The Weasley twins looked at each other and said, "It seems that our Mr. Potter is quite capable. He is worthy of being a man who can divide the house points with Miss Granger."

"Are you going to change our minds about Slytherin?"

Harry smiled awkwardly, unable to bear such words, and then said: "I think the tingling problem on the face may be related to the seal carving technique. The texture of the wood itself overlaps with the rune circuit, resulting in the runes not being smooth enough. .”

"There's nothing we can do. We tried our best. After all, our hands are not so obedient." George spread his hands.

"Can I try?" Harry asked.
