Hogwarts: Dumbledore reigned over the wizarding world.

Chapter 239 Research Findings on Twins

"Scream Shack!"

Isabella looked excited; she loved adventure and puzzle-solving, and the mental challenge fascinated her.

"Yes, congratulations on getting it right, but there's no reward." Vaughn teased as he pushed open the trapdoor and led her upstairs.

The first thing I saw after coming out of the trapdoor was indeed a shack that had been abandoned for who knows how long, but apart from the mottled walls and broken doors and windows, it didn't look particularly dilapidated or decaying.

The wooden floor was very clean, as if it had been thoroughly rinsed with a cleaning magic spell, with some watermarks still remaining between the boards.

The broken doors and windows were also cleaned up and neatly stacked in the corridor.

Most importantly, Isabella saw the electric light—

Dim yellow light bulbs travel along the mottled walls, extending from the basement where the trapdoor is located to the corridor, and all the way up the spiral staircase.

The light bulb was flickering, suggesting that the current was not very stable.

The flickering light bulbs stretched all the way upstairs, to the place where the sound had come from earlier.

The two voices were still arguing and complaining.

"I've said it before, it's unrealistic to rely solely on materials to shield a magic field from the interference of an electric field. There's nothing in the world that can block magic, Fred!"

"Your conclusion is too hasty, George. How can you be so sure it hasn't happened without even trying?"

Isabella had been in contact with the Weasleys before. She couldn't hear clearly in the underground passage and wasn't sure, but now she recognized the people upstairs as the Weasley twins.

She was a little confused as to why Vaughn had brought her to meet them.

And all that talk about magic fields and electric fields—I don't understand any of it!

Isabella followed Vaughn upstairs, somewhat bewildered. The twins quickly spotted them and ran out, wands in hand.

Seeing that it was Vaughn and Isabella, they seemed to breathe a sigh of relief: "Hey, dear brother, what brings you here, our esteemed benefactor?" One of the twins, either Fred or George, greeted them with a grin.

Another nodded to Isabella: "Good evening, Professor. Welcome to the Weasley Secret Base. Would you like a sherry, butterbeer, lemonade—or water?"

Hearing the list of drinks, Isabella was a little taken aback. She wondered if she had walked into a maze of three brooms: "Uh—water—"

"Fantastic!" one of the twins exclaimed with satisfaction. "The Weasleys secret base only has plain water—this is all at the request of our esteemed benefactor. He won't allow us to leave the Shrieking Shack. Poor us, we can only watch as the insane delicacies and fine wines of Hogsmeade are so close yet so far away!"

Isabella: "————"

Twins' thinking is always so jumpy.

Vaughn ignored their teasing and went into the room where the two had been moments before. The room was filled with various electronic parts and cables, as well as several generators that had been disassembled and seemed to be being tested and reassembled.

After glancing at it, Vaughn asked, "Is the project to shield against interference from the magic field still not going well?"

Upon hearing this, the twins, who had been joking with Isabella, looked dejected: "Yes, we've tried many materials, and simply blocking them is already a failure."

"When you proposed the theory of coupling between magic fields and electric fields, you should have stopped these time-wasting shielding experiments. It's all Fred's fault; he insisted on continuing to try to find a substance that could be immune to magic, haha!"

"What if?" Fred's face flushed red, but he stubbornly insisted, "Besides, Vaughn only proposed a possibility. The fact is, we haven't found any other way to improve our resistance to magical field interference yet. On the contrary, if we can find that material, our research can not only be applied to modifying Muggle electrical appliances, but also extended to a much wider range of areas!"

"So, may I ask you, great Fred, after wasting over 500 Galleons in two months, did you succeed?" George asked with a smirk.

Fred broke down, muttering incomprehensible things like how research is never guaranteed to succeed and how researchers' actions can be called a waste.

George grinned.

Ignoring the twins' bickering and sabotage, Vaughn examined the parts and materials on the ground.

The coupling theory of magic fields and electric fields was a hypothesis he proposed before going to North America, based on his observation of the influence of magic fields on electric fields.

Coupling is a concept in physics that refers to the phenomenon where two or more different systems interact and influence each other, thus uniting together.

Yes, the interference of the magic field on the electric field is actually a form of coupling.

Because in essence, the underlying concepts of both are the same: wherever there is electric charge, there is an electric field; wherever there is magic, there is a magic field; and wherever there is matter, there is gravity.

The so-called field is actually energy.

However, Vaughn, who initially proposed the theory, did not conduct much research on it. After all, electric fields can be analyzed using Muggle instruments, and there are countless Muggle studies available for reference. Magic fields, on the other hand, are a truly "new" concept.

Apart from him, no wizard had paid any attention to this for thousands of years.

Therefore, Fred's statement that he had not found any other way was not an excuse, nor was it because the twins were not trying hard enough. Rather, it was a theoretical deficiency, just like the development of the spell.

But it is different now.

Looking at the generator running in the corner of the room, and the disassembled parts on the ground that were actually powered and in the testing phase.

A faint light shone in Vaughn's eyes.

Photons are very special substances.

It possesses particle-like properties, representing the quantum manifestation of light, but it also exhibits wave-like properties, representing the manifestation of energy.

Of course, a photon is not actually energy; it is merely an intermediary medium for energy transfer.

But that's where it's special—energy is usually invisible and intangible, making it very difficult to study. But photons, which transmit energy, make energy research possible.

An electric field is energy.

Magic fields are also energy.

When two different systems interact, there will inevitably be collisions and energy loss. But given the fundamental rule that mass-energy does not disappear out of thin air, where does the energy go?

The answer is that it "transformed" into light and was transmitted outside the system!

Even magic still follows this fundamental rule.

In normal vision, what he saw was just a room in a shed with things scattered in a mess, but when Vorn cast the Multispectral Vision Charm, he saw endless, pulsating light in his vision!

They changed shape in his field of vision.

It appears chaotic and without any pattern.

But Vaughn knew perfectly well that the rapidly changing patterns of light waves were accurately reflecting the influence and changes between the electric field and the magical field in this room at this very moment!

Back in North America, when he desperately needed reputation points to boost his power, he even squeezed out some to develop this spell, because everything, whether Muggle creations or magic, is inseparable from light.

The three people next to him noticed the strange look in Vaughn's eyes.

The twins exchanged a glance and shrugged: "Our little brother, our esteemed benefactor, is engrossed in his research again."

"Yes, Fred, he always is like that, that's why he made a name for himself at the age of 12. You should be ashamed!"

"You're the one who should be ashamed—"

The two bickered. They only used to fight when their pranks failed and they desperately needed to shift the blame. Otherwise, they were quite harmonious!

But ever since Vaughn funded the two to do "scientific research" and then their research ideas diverged, the "conflicts" between the twins have become more and more frequent.

With Isabella present, Fred didn't want to waste time talking to George. He turned to the new professor, one of his brother's best friends, and asked, "Dear Isabella, what brings you and Vaughn here today?"

George shoved him aside: "I heard you're going to try some new teaching methods for your Defense Against the Dark Arts class, focusing more on practical application. You even went to the Forbidden Forest with Vaughn to catch magical creatures for that, right?"

Upon hearing this, Isabella, who was already having a headache from the twins' noise, was stunned.

"How did you know?"

She only found out about this today.

Fred squeezed back across from George, winking and gesturing as they jostled for the best spot opposite them: "Before we came here, the whole castle was buzzing with the news—"

"It's Harry and Ron—"

"They said you and Vaughn are preparing a special practical lesson—"

"And they even said Vaughn would be your assistant—"

"They also said that Hagrid told them all this, and the intelligence is absolutely reliable!"

The twins each said a line, performing a duet.

Isabella: "————"

She turned around and glanced at Vaughn.

Now she understood why Vaughn had mentioned not discussing the practical lessons with Hagrid before going to the Forbidden Forest today, when she wanted to visit him with a gift.

Unfortunately, because Vaughn had only said it casually, she didn't take it seriously.

She doesn't even know what the venue for the practical class will be like yet. She will only be involved in the construction tomorrow. According to the plan she discussed with Vaughn today, she plans to announce the practical class information when the class officially starts next week, as the "first fire" of the new professor!

result----

hateful!

The twins, clearly unable to empathize with her distress, continued laughing and joking: "Ron said you and Vaughn caught a fire dragon!"

"But we know he's bragging; there are no dragons at Hogwarts."

"Harry said you guys are going to bring in a bunch of really dangerous magical creatures for the practical classes, and we feel like that rumor is pretty credible."

.

"And it fits our understanding of Vaughn. Our brother, our esteemed benefactor, is particularly fond of a Muggle game called board games. If he really is your assistant, he will definitely turn practical classes into a monster's paradise."

"Hell for students!"

"Yes, George, after he first had a magical outburst and could use magic when he was eight, he locked us in the garden and made us fight the goblins!"

"Poor things, Hogwarts hadn't even started yet, and we were being chased and bitten by goblins!"

"But I still remember the reward for winning the battle: 2 silver coins, the most pocket money we'd ever received since we were kids!"

"At that time, Vaughn hadn't learned how to brew potions yet; that money was used to seduce the young girls in Saint Catchbol village—"

Fred quickly covered George's mouth, silencing him, and chuckled, "Anyway, our dear brother is a fair man. Hard work pays off, that's always been his principle. We guess he brought you here to ask us for the prize, right?"

George forcefully pulled Fred's hand away and continued, "I must say, our sponsor has a very good eye; we've developed a lot of fun things this summer."

"It's so much fun!"

"The products are even better than those at Joko's Joke Shop. Come on, Isa, we'll take you to see them."

"Yes, let our benefactor continue his research—don't disturb him for now. I suspect he's discovered something and is pondering some very profound question!"

"You're really flattering Fred, but I think you're right!"

Behind the three, Vaughn, who was using the Vision Charm to observe the light waves and thus indirectly observe the magic field and electric field, twitched the corner of his mouth.

The twins were trying to please him.

Because during the two-month summer vacation, they failed to fulfill his request to resolve the issues of interference with the magic field and magic power generation.

However, the prank items the two had been longing for, they made quite a few of in their "spare time," and Vaughn discovered them when they returned home from North America.

But to be honest, the twins' alchemy talent seems to lean more towards having fun, and they have actually created some interesting things.

Anyway, he came here today because he was interested in the gadgets the two of them had developed, and he wanted Isabella to see if they were suitable as prizes.

Since the two of them took the initiative to introduce themselves to Isha, he didn't stop them.

On the other side, the twins had already waved their wands and cast a spell to drag a large box over. Fred and George danced around the box in exaggerated movements, successfully confusing Isabella so much that she couldn't tell who was who.

One of them opened the box, took out two mirrors, and presented them to Isabella: "Dear Isabella—excuse me, esteemed professor, but please allow us to introduce you to the first product of Weasley's Magic Tricks Workshop: the Telephone Mirror!"

Another person, with a serious expression, said: "Disclaimer: The product name is temporary and may be changed later!"

Isabella, who had experience in Muggle society, knew what a telephone was.

Therefore, when the twins dramatically held up two mirror-like objects in front of her, she could hardly see any elements related to "telephone" on them.

It just looks like two square mirrors, about 6 inches diagonally.

Seemingly noticing her confusion, the twins exchanged a smile. One of them stood up, picked up a mirror, walked to the side, took out a wand, and tapped it.

The next second, Isabella saw the mirror in front of her light up, and the large face of one of the twins suddenly appeared in the mirror, winking at her.

At the same time, a voice came from not far away, through the mirror: "Good evening, Professor."

this----

Isabella's eyes widened.

Noticing the change in her expression, she saw the twins in front of her and in the mirror, looking at her smugly.

Then, Isabella gave the two of them a strange look: "Isn't this just a two-way mirror?"

'

,

"No!"

The twins suddenly screamed, startling Isabella.

Their faces flushed, and they leaned closer, eager to explain the difference between a telephone mirror and a two-way mirror: "They're completely different, Isa! You can't tarnish our invention with that outdated stuff!"

"Yes, Fred is right—although two-way mirrors have their merits—"

"Shut up, George!"

"Okay, Fred."

"In short, the two-way mirror is a completely illogical gold artifact. Do you understand what illogical means? It means that its creation has no principle. It's just two mirrors. As long as they belong to two different wizards, those two wizards can use it to communicate, as if they were only separated by a mirror!"

"Yes, but our telephone mirror is different. It has a principle, and the principle is very scientific—well, you should understand science, right? Light signals? Sound signals? It doesn't matter if you don't understand. You just need to know that every telephone mirror we invent is a receiving and transmitting terminal. After it is activated, it will automatically collect light and sound within a certain range and then send it to other terminals to achieve communication between multiple terminals. Of course, this inevitably leads to its effective range being narrow, far less than that of a double-sided one—"

"Shut up, George!" Fred snapped again.

Isabella was completely confused, so she asked the crucial question: "So, what is its purpose?"

"To contact, to make a call!"

"But don't we already have two-way mirrors for communication?"

The twins grew anxious and began trying to explain to Isabella the advantages of the telephone mirror over the two-way mirror.

But Isabella couldn't understand a word they used, which was constantly talking about things like sound and light signal relay and multi-terminal interconnection.

Then Vaughn's voice suddenly broke in: "The call function is the most basic function of the telephone mirror. What I originally wanted them to develop was something with many functions, not just a simple telephone!"

The three turned around and saw that Vaughn had finished his observation and was walking over.

He took a mirror from Fred's hand, tapped it lightly with his wand, and a dazzling rainbow-like light appeared on the mirror.

At the same time, the same light effect appeared on another mirror.

Isabella looked at Vaughn, puzzled.

Vaughn prompted, "What if that light just now turned into an exam paper? Or a piece of text, audio, or video broadcast? Or to be more specific, a recording of a lecture by another professor in your field? Or perhaps—"

As Vaughn proceeded with his hypothesis one by one.

Isabella's expression gradually changed from confusion to surprise.

She looked on with a sudden realization: "The Internet?"

During her nearly two years of travel, Isabella visited many countries, especially North America. To avoid being captured by the Magical Congress, she disguised herself as a Muggle for a long time and lived like one.

She was no stranger to Muggle information technology.

But it's not surprising that she was so slow to react. After all, in 1992, the new information revolution in Muggle society had only just begun with President George H.W. Bush's "Information Superhighway" plan in February. The multimedia information transmission network was still in the legislative stage and would not begin construction until next year.

Therefore, the internet in this era was very barren, far less vibrant and diverse than it would be 30 years later.

However, some prototypes have already appeared, such as BBS and chat rooms.

She didn't understand some of Vaughn's assumptions, but some of them corresponded to her understanding of the Internet.

But she couldn't imagine what the final product would look like.

After all, the concept of a smartphone was something that even science fiction movies couldn't imagine in an era when mobile phones were still bulky bricks.

Yes, the thing Warn arranged for the twins to develop before the summer vacation was a smartphone.

Of course, that's just the ultimate goal.

The explosion of smartphones is due to two main factors: firstly, the development of microelectronics technology, which enabled the realization of smartphones as a terminal product; and secondly, the decades-long development of the network, which provides sufficient content depth to support mobile networks.

In a Muggle society, Vaughn certainly wouldn't have started a smartphone project right away, firstly because the technology wouldn't be there, and secondly because the network wouldn't be mature enough.

But in the magical world, such concerns do not exist.

For example, the technical problems of realizing terminal products, in the magical world where miracles are created using magic, many problems that are difficult for Muggle society to solve can be solved directly through "miracles" using magic.

The telephone mirror collects sound, light, and image data, converts it into information packets, and sends it out. In Muggle society, this is an extremely complex audio-visual system. However, in the telephone mirror developed by the Twins, they only need to borrow a few already mature blockchain tokens to handle the Twins. Their sensitivity to the Transformation Mirror stems from their borrowing (copying) of it.

As for whether the network is mature or not, there is no need to worry. The magical world is a small market with only tens of thousands of people. Simple functions are enough to meet the initial needs. Once the initial dominance is achieved, it will be difficult for such a small market to allow the birth of a second competitor.

Of course, as a novel concept product that has never been seen before, the telephone mirror is not without its flaws.

Vorn Opens the Vision Spell.

Amidst a vision filled with "light pollution," he eventually recalled the ripples connecting the two mirrored women by constantly adjusting the frequency.

That's a signal channel.

The twins designed an information transmission system based on his needs from two months ago, simulating the Muggle's requirements. Of course, due to the differences in technology and implementation methods, this information transmission channel has almost nothing to do with the Muggle rate; it is entirely magical.

What are called ripples are actually more like an illusion.

Even from Vaughn's unique perspective using the Vision Charm, one could still recall something resembling an image from the flowing light trails.

A constantly moving, blurred image composed of color blocks and blurred outlines.

It gave Vaughn a sense of déjà vu, like the presence of ether!

Modern alchemy, which developed the theory of the golden soul, never distinguishes between inanimate objects and living things.

Ether connects all things, and all things connect to ether.

The twins naturally lack the ability to use ether as a channel for information transmission; after all, Vaughn would certainly not be able to recall its existence through the Vision Charm.

He guessed that this was some kind of ether-like method.
