Ancient wizards return to Hogwarts.

After trying hard to suppress his strange thoughts, Rice patiently explained to Helga what the Internet was.

After listening to Rice's explanation, Helga had the most intuitive impression of the Internet: "So the school owls are going to be unemployed?"

Les:?

"No, this is limited to the school. Students still have to rely on owls to send letters to their families and their families still have to rely on owls to send things back to them, at least for now." Rice will not take too big a step at a time. He plans to try to promote it within Hogwarts first - if he can replicate the Internet.

Once his network is running properly at Hogwarts, he will gradually extend it to wizarding families.

As for the name of this network, Rice decided to call his network "magic network" - magic network. However, all this is his idea, and he hasn't even drawn a sketch yet.

"Then what's the use of your [net]?" Helga was a little confused. She didn't know why Salazar went to so much trouble to create a "net".

"It's convenient for transmitting information. For example, today I want to ask you to find Dumbledore to verify a piece of news. If there is an Internet connection, I don't have to go to your office, and you don't have to go to Dumbledore to find out the truth. There are countless other conveniences."

"Oh? So if I want you to help me make a doll, I can just send you a message?" Helga grasped the point immediately.

Les closed his mouth.

For a moment, his desire to create the magic network was extinguished by Helga.

Of course, the naive Rice didn't know that there is such a thing as "read only but not reply" in the world.

After making a half-serious joke with Les, Helga left her room and headed for Dumbledore's office.

"Honey Toffee."

With a command, Helga walked into Dumbledore's "territory".

"Please take a seat, Professor White. Would you like some tea or candy?" Dumbledore was a little surprised to see that the visitor was Smith White. He quickly pulled out a chair for Helga and summoned a pot of hot tea and a plate of candy.

"Although I don't know much about health preservation, my intuition tells me that an elderly person shouldn't eat so much sugar." Helga couldn't help but complain about Dumbledore's taste.

Whether it is the office password or the candies he serves to guests, the principal's obsession with sweets is revealed.

Helga couldn't help but think of an old friend, but that guy's physical condition was much better than Dumbledore's. She and Dumbledore together couldn't outlast that old guy.

"I'm over a hundred and ten years old, so I can eat whatever I want!" Dumbledore said with a smile, "Besides, sweets can make people happy."

"It's a familiar statement." Helga couldn't help laughing.

It's really interesting that these two guys have such a strange resonance in this regard.

"So is there something going on?" Dumbledore changed the subject and got to the point.

"There is indeed something I want to ask." Helga told Dumbledore that electronic devices would be interfered with around Hogwarts.

"Is this a defensive spell cast by some headmaster later? The Muggles in our time didn't invent such newfangled gadgets."

Dumbledore shook his head, indicating that he didn't know either.

"You saw it in A History of the School, right? This is not a deliberate arrangement of the school, but a matter of experience. Through long-term observation, people have found that electronic devices will malfunction after entering the range of Hogwarts."

"That's interesting." Helga responded thoughtfully.

"Is it magic?"

"That's unknown, but it's highly likely. Other magic schools also have this phenomenon, but they don't have founders who are comparable to Hogwarts."

Dumbledore was as confused as Les and Helga, but over the long years he came to a conclusion through observation: magic would affect the electricity in electronic devices.

"How come you think of such a question?" After giving his own answer, it was Dumbledore's turn to ask a question.

Helga tried to introduce the Internet to Dumbledore, which Salazar had introduced to her. However, the information became a lot more blurred after she passed it on. Dumbledore didn't quite understand what she was talking about, but he knew that it seemed to be a new gadget used by Muggles to transmit information at high speed.

"What a novel concept." Dumbledore said with emotion: "It seems that I should really suggest to the Ministry of Magic to update the teaching materials of Muggle Studies."

He also vaguely felt that the Muggle world seemed to have undergone earth-shaking changes, but Dumbledore did not take this "little thing" to heart, because Voldemort had always been like a sharp fishbone stuck in his throat.

Compared with Voldemort, what are the little inventions of the Muggles?

Voldemort was like a leaf stuck in Dumbledore's eyes, leaving him no time to pay attention to anything else.

"In fact, in addition to the Internet, I have another consideration, about the school's anonymity." After Helga described the Internet to Dumbledore, she added a few more thoughts of her own.

The Muggle-Repelling Charm and a series of concealment magic around Hogwarts are mostly based on a series of spells set up by the four of them when they founded the school. Later headmasters and professors may add some of their own designs to this system, but the overall structure is still the same as what they arranged back then.

Helga has verified that the magic circles in the nursing school are not much different from those a thousand years ago.

Taking building a house as an example, Salazar and the other four were the ones who laid the foundation, built the load-bearing walls, erected the beams, and set up the main pillars. Their successors were no more than just opening a skylight on the roof and putting up wallpaper on the walls.

When the school was first established, the four founders never considered the issue of electronic equipment.

Although the wizarding world was lucky and magic could make electronic equipment malfunction, this was not a solution after all. No one could guarantee that Muggles would not invent more powerful detection equipment, and no one could guarantee that they would not discover the existence of Hogwarts through the detection equipment.

This time Dumbledore was completely silent.

"Perhaps we should further upgrade the school's protective magic." Helga came to her own conclusion.

"Hmm." Dumbledore's eyes flashed with a thoughtful light.

Professor White had a point. After so many years, it was time for Hogwarts' defensive magic to be updated.

"Take your time to think about it. I'll go back first. We can discuss it again when we have a chance in the future." Helga felt that her mission had been accomplished and her goal had been achieved, so she went straight back to her office.

Back in the office, Helga found Salazar reading a book intently.

Looking at her old friend who sometimes frowned and sometimes sighed, Helga couldn't help but ignite an endless desire for knowledge: it was the first time she saw such a complex change of expression on her old friend's face.

"What are you looking at? You're concentrating so intently." Helga sat down opposite her old friend.

"An encyclopedia, given to me by Rowena's student." Les handed over the book in his hand.

"I suggest you take a good look at it. It will help you understand the Muggle world - it's much better than our Muggle Studies textbooks."

Helga took the book and found that Salazar was studying something called "artificial satellite".

"Artificial... satellites? Muggles can actually make such things and have the ability to send them into the starry sky? It's incredible." Helga had a new understanding of the development of Muggles.

It is difficult for people to suppress their desire to explore the starry sky, and this desire has never changed since thousands of years ago. Helga once looked up at the starry sky, wondering what the depths of the universe that brought magic to the world looked like, and how could she not be shocked that the Muggles had taken the first step in exploring the starry sky before her?

"More than that..." Les seemed to be hesitant to speak. He was quite worried at the moment because he knew more about satellites than Helga.

This thing is more than just exploring the universe. Helga thinks the Muggles are too selfless.

The book says that satellites can see buildings on the surface, and it also provides a photo of the building from a satellite perspective.

This gave Rice a little Muggle shock.

After learning this new knowledge, Leston felt as if a thorn in his back was really there, as if there really was an eye in the space hundreds of miles away, coldly scanning the earth, sky, and ocean.

He was somewhat disturbed by modern Muggles. They might not have discovered the wizarding world yet, but with the help of satellites, it was only a matter of time.

No one knows what fate the wizards will face after being exposed.

Rice suppressed the complicated emotions in his heart and asked Helga if she had gained any news from Dumbledore.

After sharing Dumbledore's retelling and speculation with her old friend, Helga looked to Les to get his opinion.

"Dumbledore is knowledgeable, and I tend to believe that it is magic that interferes with Muggles' electronic devices." Rice expressed his support for Dumbledore.

"But he doesn't have much knowledge. He completely ignored the development of Muggles and watched the magical world stagnate." After expressing his agreement, he expressed his dissatisfaction with Dumbledore.

"He is old after all, and he has never experienced a life like yours before." Helga rarely excused Dumbledore: "For Dumbledore, the most important thing is the dark wizard, Voldemort."

Hearing the name, Rice snorted heavily.

This guy is like a cockroach, disgusting to see but impossible to kill.

"And since magic can interfere with electronic equipment, that's good news after all. We don't have to worry about Hogwarts being discovered by Muggles for the time being." To this day, Helga also feels that the magical world cannot be exposed to Muggles - their attitude towards wizards is unknown, and their strength is overwhelming, so they must be treated with extreme caution.

Just like a lone wolf entering the lion's territory, they have to be cautious in every move they make.

Helga thought her words could make Salazar feel better, but she didn't expect him to shake his head.

"It can only interfere with electronic equipment, right?" He casually picked up a quill on Helga's desk and turned it and its casing into a spear thrower.

Then he swung his spear with all his might, and it flew out of the window, brushing past the body of a raven in the sky.

Ignoring the cries of ravens outside the window, Rice stared at Helga and said word by word: "Pure machinery will not be affected."

Don't underestimate pure mechanics. Bows and crossbows are mechanical, and so are muskets and cannons.

"Isn't there a Muggle-Repelling Charm—"

"What's the range of this spell?" Les interrupted Helga. "What if we stand outside the range of the spell and observe it with mechanical equipment? Muggles should be able to do it with their technological means, right?"

Helga frowned.

These problems would not have been a problem a thousand years ago - someone who could discover the existence of Hogwarts from dozens of miles away could not be a Muggle, but they are a problem in modern times.

"And those satellites can take pictures from the sky - turn the page in that book if you don't believe me."

Helga did as she was told, and when she turned to the next page, her face suddenly changed: the book came with a satellite photo of Constantinople.

"Satellites are also electronic devices..." Helga said dryly, and she felt a dryness in her mouth.

Muggle technology was somewhat beyond her expectations.

Who is a wizard who can take pictures of the Earth from hundreds of miles above it? Can a wizard do this?

Helga felt that after expanding her domain, she could indeed sense the topography of a very large area, but apart from herself, Old Viper and Old Raven, which other wizard could do it?

"It uses optical equipment. The book says it uses cameras, spectrometers and other miscellaneous things to measure visible light and infrared radiation from the Earth's surface, providing high-resolution surface images and spectral information."

Helga felt like she could understand each word, but taken together it was very confusing.

The more Rice spoke, the more emotional he became. He slammed the table and told his old friend that she really needed to catch up on her studies.

"This is light, not electricity. I don't think our magical interference is effective. Maybe the photo of Hogwarts is already lying in the storage of some institution, but they haven't discovered the abnormality yet."

Helga:! ! !

Her mind went blank at her old friend's words.

Fragments of knowledge floated in Les's mind and finally connected into a line. He felt that he had found a solution to the problem.

"There happens to be a meteor shower in January, and the structure of the meteorites is rock and ice crystals, which is amazing," Les said with a slight smile. "Helga, our domain is enough to interfere with the meteorites above the earth and guide their trajectories, so that we can destroy all the Muggle satellites in one go - this means that Hogwarts will not be exposed. We must take the initiative to eliminate the means by which the Muggles may observe Hogwarts. This is a race against time."

Helga's eyes widened in shock at her old friend's train of thought.

"What do you think? If possible, let's act together--" Les thought he needed the help of his old friend.

"Salazar, wait a moment!" Helga called out, quieting Salazar down.

"Your ways are so Gryffindor."

Such a simple sentence immediately diverted Rice's attention from the satellite.
