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

He'd heard of the love-hate relationship between the Weasley twins and Mr. Filch, the castlekeeper, and though he didn't know exactly what Fred and George's tricks were, it was interesting to think about it.

Maybe it's a good practical topic, but he's not a person who can sit still.

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

"Then you can try, let's study it together. My name is Fred, Fred Weasley, and you should know my brother, another Weasley. ”

"I'm George."

Harry shook hands with them, and was about to introduce himself when he was interrupted.

"Of course, we know." Fred laughed.

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

"Oh yes." Fred put an end to his rambling and pulled out a mask from under his clothes.

The mask is wooden, white, and not very carefully carved, as if a curved wooden plank that barely fits the lines of the face has been cut out of the eyes, nose and eye.

Potions were still too expensive for Fred and George to develop, and after being inspired by Munn, the two decided to use the mask form.

And this mask is made of fir. Among the woods suitable for Transfiguration, ebony and fir have always stood out, and are even often used as wands, as Professor McGonagall's wand is.

At the same time, firs were cheaper, and Fred and George were more than able to afford them.

"After being inspired by you last time, we succeeded in making the finished product."

"And the problem you're having now?" Mu En looked at them curiously.

George smiled, "We'll show you how." ”

Turning to face everyone, he clapped his hands slightly: "Everyone, everyone, sorry to disturb for a moment, I don't know if I can delay everyone for a minute." ”

There weren't many rules in this reading room, most of the people were just relaxing here, and a few learners didn't mind too much when they saw that it was Fred and George.

They have a good reputation for being outside of Slytherin and are always alive and well.

"George, what tricks did you come up with?" Someone was curious.

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

Harry's eyes widened as he looked at Muen curiously.

Mu En smiled back.

George was introducing when he suddenly felt a sinking in his hand.

I saw Fred put the mask in his hand and quickly took two steps back: "Yes, George will make a demonstration for everyone next!" ”

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

Fred hurriedly waved his hand: "Don't shirk, George, everyone is looking forward to it." ”

The two pushed each other twice, and finally George could only smile and nod helplessly, while there was a boo below, laughing and urging them.

Harry could vouch for it, he heard George mumble, "Damn, I didn't expect to bring Ron." ”

Fred held back a smile and reminded in a whisper: "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 resolutely put his mask on.

Harry whispered curiously, "Are there any side effects on this side?" ”

"It's nothing, it's just that my face hurts and itches." Fred whispered, "It's like someone is pricking you with a needle." ”

Harry felt a little furious and looked at George carefully.

I saw that after George put on the mask, the mask suddenly squirmed, wrapping George's entire head like a horror movie.

Then, the hairs on the mask began to emerge, and the entire face began to bulge forward.

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

At the same time, Harry also saw George's body trembling, and it was obvious that the so-called pain and itching were not simple.

In a short time, George's entire head turned into a fitting lion's head, with a thick mane that reached over his shoulders, and looked extremely formidable.

"Merlin's beard!! George, can you still talk back? The wizard who had just spoken whispered.

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

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

"The problem now is the dynamic capture of the facial features?" Harry said, "It's because it's the mask that transforms, not the actual head that turns into a lion." ”

"That's right." Fred nodded, looking at Harry with some surprise.

"Oh, George, may I try it?" Someone was curious enough to come forward.

"Sorry, it's not a complete study yet. However, we tried to get the finished product out on Halloween Eve. George said quickly, and then he couldn't help it anymore and quickly took off his mask.

He put his hands behind his head and lifted the mask as if he were tearing and molting, and after the mask fell off his cheeks, it quickly reverted to its wooden appearance.

And he rubbed his face carefully.

"This is our new work." Fred introduced.

"Can it be made like something else? Like eagles? "There's a Ravenclaw one to say.

"Absolutely!"

"Can there be a shape that is beyond human imagination?" Someone is curious.

"Are there any cats?"

The eyes of the three men and the cat immediately fell on the person who spoke, it was a Hufflepuff girl, and when she noticed the sight, her face turned red.

"Uh... No... Mr! She quickly explained.

"I think it's a good proposition, as long as Lady Loris doesn't mind." Mu En smiled.

Lady Loris was one of Filch's old cats, skinny and hairless, with a terrible bark, and many in the castle hated him.

When the girl heard this, she understood that Mr. Jones did not mind, and laughed a little awkwardly.

After a long more fuss, Fred and George turned around, handed the mask to Munn, and said the two problems they were encountering.

Expressions are out of sync and the face is tingling and itchy.

Mu En took a look, and after his explanation last time, the Weasley brothers chose to make masks by carving runes on seals.

Once upon a time, they made magic items by applying spells to items and then solidifying the spells. Or make a special joke potion into candy.

And the current seal carving technique is actually equivalent to alchemy, you must know that this is not a mainstream discipline. George and Fred had a lot of trouble making such a finished product.

Mu En gave the mask to Harry after two glances, "Look at the spell in here. ”

The Weasley brothers' seal carving skills weren't very good, and the rough rune grooves were displayed all over the mask.

Harry looked at it, and there were many circuits that he didn't quite understand, but he still vaguely recognized some of them.

"Hmm... All I could see was the face detection inside the mask, the flowing wraps, and the runes of the curing technique. The outside of the mask should be a directional transformation rune in the shape of a lion. ”

The Weasley twins glanced at each other, "It seems that our Mr. Potter is not a small man, and he is worthy of being able to divide the house points with Miss Granger." ”

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

Harry smiled awkwardly, a little unbearable at such words, and then said, "I think the problem of facial stinging may be related to the seal carving technique, the texture of the wood itself overlaps with the magic script, resulting in the rune not being smooth enough. ”

"No way, we tried our best, after all, our hands are not so obedient." George spread his hands.

"Can I try it?" Harry asked.
