It's in your textbooks. "

"You dated me just to peek at my seventh-grade textbook?" George said sadly.

"Of course not, George," Gwen said. "Then why don't I go out with Angelina?"

"Don't even think about it!" Fred sternly stopped.

"The conclusion is," Gwen continued, ignoring the twins, "The Changing Charm can't transmit sound, it can only change appearance."

"We solved a problem for you," said Fred, and George pulled out a pair of small ears from his bag, this time without the long string of meat, just a small ball of meat behind each ear.

"We first shrank the connected meaty rope, and then used a few transformation spells—" George turned his ear to show Gwen, "Theoretically, these two balls can be connected, but the effect will not be as good as the meaty rope .If we want the sound and accuracy of the telescoping ears, there needs to be a connection between each pair of ears—like a floo network between fireplaces."

Gwen felt dizzy when he heard it.Then trotted all the way to bring a few thick books: "How to Clean Your Fireplace", "Seven Secrets of Portkeys", "Analysis of Apparition Theory", "Magic Items for Conveying Messages among Wizards".

"We're going to make a lot of money." Fred said while reading "Magic Items". "There is no decent sound transmission item in the wizarding world—how can the Patronus be counted as one?"

"Portkey transmission is usually one-sided, and some are one-off. We don't need to be complicated enough to transfer people or objects from one space to another, as long as there is sound."

"The Floo Network is entirely in the hands of the Ministry of Magic," said George, closing the wonderful fireplace book. "There are no useful charms on it."

"Maybe we need to incorporate some alchemical methods," Fred said.

"A small magic circle?" George immediately understood what his brother was talking about.

"We have known each other for the sixth year," Gwen said with emotion, "but I am still shocked by your genius ideas from time to time."

The twins bowed gracefully, "But we haven't studied ancient runes."

Gwen tilted her head and thought for a while, before writing a few rune characters on the parchment. "This," she said, pointing to a crooked letter that looks like an R, "raidō, the ancient Fusac word originally meant a currency carriage. It symbolizes movement and exit."

She pointed to the other two letters, "sowulo and perro are the entrances and exits from the spirit to the entity. These runes have powerful magical powers, and even when written on paper, you can feel the magic flowing—"

"Flow?" George seemed to think of something, "If the sound can flow like water or wind..."

Gwen heard the string and knew the meaning, and wrote another small character.Then, with the help of the twins, different combinations were tried.

"Come on, Gwen." Fred encouraged.

Gwen controlled her hands not to shake, "Don't talk, Fred. This is a rune, and it would be disrespectful to Odin to try indiscriminately. What if I draw it crookedly."

"Then Merlin will save you," said George. "We're right behind you, don't be afraid."

Gwen held her breath, took the golden carving knife she used in the ancient magic literature class, and carved words on the smooth and soft ears.

When a circle of runes appeared on the pinna, she was already sweating profusely.

"Is it still too late to send you guys to retake the course?" Gwen asked as she sat on the ground with no image, panting.

"Professor Babling won't," said the twins, grinning. "Come on, let's try."

The three came to a long, thin, empty classroom, Fred striding to the end of the room with one ear in his hand, George and Gwen standing on the other side.

"Hey, hello, can you hear me?" Gwen whispered into her ear.

Fred over there pressed the stretch ear tightly against his own ear, and could only hear the rustling sound.Then he also said into his ear, "What are you talking about?"

George could only see his brother's mouth opening and closing, but neither he nor Gwen's ear moved.

"Hey! Hey! Can you hear me---!!!" Gwen tried a few times but didn't respond, and yelled loudly into the telescopic ear.

This time Fred jumped up, and he clasped his ears and yelled dissatisfiedly: "Speak up more! Gwen! There are a few spiders on the edge of the Forbidden Forest that can't hear you calling."

Instead of summoning the eight-eyed spider from the Forbidden Forest, it was Filch who knocked open the door.

Administrator Filch came in wheezing.His sunken, veined cheeks were purple, his chin quivered, and his thinning gray hair was disheveled.Apparently he's come all the way.Mrs. Norris trotted after him.

"Aha!" said Filch, shuffling a step towards the classroom, his flabby cheeks quivering with anger. "What are you guys doing?"

The twins folded their arms and glared at the administrator.Gwen noticed the little movement of their ears retracting.

"No matter what you're doing," the old caretaker seemed in a good mood, "things are changing at Hogwarts, Weasley brat, and you, restless girl."

He must be referring to the Ministry of Magic's new Education Order. "We saw it," said Fred coldly.

"Very well. I've been telling Dumbledore for ages and years that he's been too lenient with you," Filch said, chuckling harshly, "if you knew I had the power to beat you to pieces with a whip, You mean little bastards never throw stink bombs again, do you? If I could hang you by the ankles; hang you upside down in my office, no one's going to throw teeth in the hallway It's a flying saucer, isn't it?"

"Hand over what's in your hands now." He said, and then walked towards George. After a while, George took out something from his arms and threw it to Fred at the other end of the classroom. .

Furious, Filch ran to Fred, panting. The tall, red-haired boy whistled and tossed what he had just received to the far side of the classroom.

When Filch turned his head and ran again, George and Gwen, who were standing there just now, had disappeared. Looking back, even Fred had disappeared.Filch was stomping his feet in the empty classroom angrily, and the little bauble that had been thrown on the floor had already fled quickly on the floor, making loud noises.

"What is this?" Gwen asked George, looking back as she ran.

"Enhanced decoy bomb, used to attract attention, but it was a failed product—"

"We could have thrown a few more rounds to get old Filch in motion, but that thing might explode in our hands—"

Gwen gave a thumbs up: "You guys are professionals when it comes to sabotage."

The twins and Gwen's modified stretch ear experiment was still not ideal. They felt that they were only one step away from success, but no matter what method they used, they couldn't cross that line.

"Think of the best, Gwen." Fred tossed his flesh-colored ear over and over again, and then caught it with the other hand, "I heard half of what you said to your ear yesterday."

"And we were only thirty feet apart." Gwen was a little frustrated.

"We can go to Hogsmeade for inspiration," said George cheerfully. "Don't forget about that!"

That's right, a big event that can cheer up the three of them.

On the first weekend in October, Gwen was first dragged by the twins to Zuko's joke shop.The boss there had recently seen Fred and George grimacing, and he had realized that his old customers had now become potential biggest competitors.Then they turned into a side road with a small bar at the corner.A tattered wooden signboard hung from rusty brackets over the door, and it bore a picture of a chopped-off boar's head, blood seeping through the white cloth it was wrapped in.The sign creaked in the wind as they approached.The three of them hesitated outside the door.

"Right here?" Gwen couldn't believe her eyes, "Is this place safe?"

"I think my girlfriend is so naive sometimes," George joked to Fred. "If we're going to be in an 'after school group,'" he bites the word, "we can't go to the Three Broomsticks or Madame Puddife's Tea House."

"Come on, let's go in." Fred led the way in.

The inside is nothing like The Three Broomsticks, where the big bar always feels bright, clean and warm.The Hog's Head was just a small, dark, very dirty room, with a strong mutton smell.The bay windows were so thick with grime that little light could penetrate, and candle stubs were burning on rough wooden tables.At first glance, Harry thought the ground was compacted mud, but when he stepped on it, he realized that centuries of grime had accumulated on what was originally a stone floor.

Hiding your face seems to be all the rage at the Hog's Head.There was a man at the bar with his whole head wrapped in a dirty gray bandage, but still pouring glass after glass of something smoking and flaming through a slit in the bandage over his mouth.Sitting at a table by the window were two hooded figures who Harry would have thought were Dementors had they not been speaking in thick Yorkshire accents.In a dark corner by the hearth sat a witch, a thick black veil hanging down to her feet.They could only see the tip of her nose because it pushed the mask up slightly.

The three of them were holding big paper bags full of things they bought at Zonko's joke shop.After pushing open a wooden door of the bar, Gwen couldn't help calling May
