Ancient wizards return to Hogwarts.

"Helga, do you know what you are saying?" Les stared at Helga with dissatisfaction, expressing strong dissatisfaction with what she said.

"I know." Even though it was obvious that her old friend's anger was ignited by her, the expression on Helga's face did not change at all, as if what she had just said was a natural truth like "the sun rises in the east and sets in the west."

"Oh? Tell me, why am I a Gryffindor?" Helga's attitude made Les even angrier, but after his anger reached a certain level, Les calmed down.

He said directly, Helga, since you say I look like a Gryffindor, then convince me. If you can't convince me, don't blame me for getting angry.

"Because you chose the most Gryffindor solution." Helga was calmer than Leslie. She started analyzing the consequences and impact of his actions.

"We can use a dichotomy to analyze this problem. First, there are two situations: Muggle satellites have discovered the wizarding world and Muggle satellites have not yet discovered the wizarding world.

If it is the former, then the fact that Hogwarts has not been razed to the ground shows that Muggles think wizards are harmless or even beneficial. Their attitude is clear: Muggles want to live in peace with wizards. If you destroy all the satellites at this moment, it will only destroy this relationship and bring disaster to the wizarding world."

Helga's eloquent description reduced Les's anger a little, and he planned to continue listening to Helga's analysis.

"If the Muggles haven't discovered the wizarding world yet, there are two possibilities. One is that their satellites can't detect us at all, so you don't need to consider destroying the satellites. The other is that their satellites have the ability to detect us, but the Muggles haven't realized it yet."

"I'm talking about the last situation--" When Les heard Helga's second situation, he immediately interrupted and said that even if the Muggles could not find Hogwarts with the existing technology, they would be able to find it one day as technology gradually developed in the future.

"That's how you're like Godric. I bet he would want to destroy those satellites in the sky as soon as possible."

"He can't destroy it." Rice said confidently.

Godric's domain is [Fire], which is of no use in this matter.

Helga:…

She resisted the urge to cast a silencing spell on Salazar and continued to analyze him.

"So what if it can be destroyed? Will you alert the Muggles by doing this? After all, so many artificial satellites in the sky above the earth were destroyed at the same time..."

"So we have to use the cover of the meteor shower, otherwise we can use our domain to send a bunch of rocks up there right now."

"But even if you destroy all the satellites, the Muggles will believe that it was an accident caused by the meteor shower. Then can't they just launch new satellites into space? I read in this book that satellites are involved in many fields, and Muggles will not give up.

Of course, if you say that we should wait until they launch a new satellite and then blow it up with a 'meteor shower', I think you are treating Muggles as fools."

Les:…

"As long as there are enough satellite fragments, a garbage belt will be formed in the low-Earth orbit, making it impossible for Muggles to launch new satellites." Rice gave his own answer. This is also the concept he read in the book.

Muggles themselves think that as the amount of space debris in low-Earth orbit increases, the difficulty of satellite launches will gradually increase. He just accelerated the process.

Helga:?

"How many satellite debris would be needed? Hundreds of thousands, millions? Would it really have an impact?" Helga was skeptical.

Les choked.

He thought about it carefully and found that this did not seem very reliable.

The circumference of the Earth is 40,000 kilometers, and the low-Earth orbit can be seen as a circle with a larger radius, so the circumference will only be larger. More importantly, this orbit is not a line, but a surface. How much space debris would it take to fill this area?

Rice thought that this might happen someday in the future, but not now. Humans had only been launching spacecraft into space for a few decades, so how many were there in total? Even if he and Helga used all their strength to smash them all, how much space would they occupy?

However, Helga did provide him with a new idea: launch one and blow it up. This idea seems worth a try?

The Muggles don't know about the existence of the magic world, so they won't suspect them. Instead, they can use this to sow discord between Muggle countries...

After hearing Salazar's new idea, Helga was a little speechless.

"If you want to worry about that, go ahead. I won't make trouble with you anyway. And you haven't reacted yet? Think carefully about the conversation you just had with me. He acts on whatever he thinks of without considering the consequences, and after being dissuaded, he comes up with another new unreliable idea. Don't you think this kind of person looks familiar?"

Les was completely silent.

After being pointed out by Helga, he realized that his behavior was indeed somewhat similar to that of Gryffindor.

"Admit it, Salazar, Godric had a huge impact on you. This influence did not disappear even after you left Hogwarts and slept for a thousand years. Instead, it became more obvious because your body has become younger." Helga showed an honest smile and said words that Salazar would never accept under normal circumstances.

She had noticed that Salazar's personality seemed to have changed a lot after returning to youth. She originally thought it was because of his younger body, but after experiencing what happened today, she realized that after decades of getting along with Godric, Salazar's personality had long been "infected" by Godric.

Before, his original character suppressed it and it was not obvious enough, but after sleeping for a thousand years, the traces of the lion in his heart were finally exposed.

This is perfectly normal, Godric is just that kind of man, he has a subtle influence on everyone around him, just like the sun shining brightly.

But fortunately, I stopped him, otherwise God knows what terrible things this guy, who has a bit of Godric's shadow in his character but is still Salazar at heart, would do.

Salazar's actions could be extreme in order to protect what he held dear.

Without her, the magic world, the non-magical world, and even the whole world would be doomed! Because only she can control Salazar, an extremely dangerous wizard.

Les:…

After thinking carefully for a moment.

Les:! ! !

"Helga, what nonsense are you talking about! I just, just had a change in the hormone secretion in my body, which can indeed change a person's personality. If you don't believe me, you can read the book. It's in the book! This is the drawback of my method of immortality, haha..." While defending himself, Rice searched for the remaining encyclopedia in the small leather bag.

"Well, it's a hormone problem." Although she didn't know what hormones were, Helga said she believed Salazar's words completely. Really, she believed them.

It must be a coincidence that your first student has a field in Godric's department, right?

Seeing Helga's reaction, Les began to search for books more vigorously. He must find the encyclopedia about hormones and let Helga know how wrong she was.

"Eh? Then why do you react so violently to the Muggles' satellites? Is it because you are afraid of them?" Helga wanted to provoke Salazar and tease him with this, but unexpectedly, Salazar stopped moving his hands.

After thinking hard for a while and examining his own heart, Rice sighed.

"Although I don't want to admit it, I am a little scared of them. They are developing too fast."

Helga was stunned.

Am I still asleep? Is this something that Salazar Slytherin would say?

She believed that her other old friends would be as shocked as she was when they heard Salazar's words.

"A hundred years ago, the skills used by Muggles were still within my comprehension, and the wizarding world was only slightly behind them. For example, the Hogwarts Express was the Muggles' means of transportation at that time.

But only fifty years later, the Muggle world had changed dramatically and they controlled the sky, the land and the sea.

On land, they have cars and trains. Two places hundreds of miles apart can be reached within a day by train. They have advanced communication methods, which allow them to communicate over a distance of tens of thousands of kilometers. They can fly into the sky for long-distance travel, transportation and even attack. They are no less impressive on the sea, with ships and submarines, making the sea and the surrounding areas their domain.

If we count forward another twenty years, their tentacles will have reached the cosmic level.

Today, in just a hundred years, Muggle technology has developed to a level that we cannot understand, and it has become almost impossible to catch up with them.

I dare not imagine what the world will be like if they wait another hundred years for them to develop.

Why do you think I'm afraid of Muggles? If you knew them as well as I do, you'd be afraid too."

Now it was Helga's turn to be silent.

After hearing what Salazar said, she also realized how terrifying Muggles were. Their development speed was a bit too alarming, and Salazar's reaction was more intense than hers because he understood Muggles better than she did.

In this situation, he was still only thinking about destroying the Muggles' satellites to make Hogwarts better hidden, which was already extremely restrained.

If it were him from the past, he would have probably started to recklessly restart his research back then - those large-scale sustainable magics that were blocked by the three of them.

"It is urgent to replace the textbooks of Muggle Studies." Helga did not continue to dwell on the two topics of "fear of Muggles" and "you look like a Gryffindor", but began to think about ways to solve the problem.

There are two very urgent things facing her and Salazar now. One is to change the textbooks of Muggle Studies, and the other is to update the school's defensive magic.

"You're right." The anger in Rice's heart had completely dissipated, and even his attention had been successfully diverted by Helga. He no longer stared at the Muggles' satellites and thought about how to quietly blow them up.

Les and Helga really put the previous topic aside and began to think about these two questions seriously.

After pondering for a moment, Rice had an idea.

"I think if we want to hide, we need to pay attention to two aspects. One is to drive away the Muggles who stray into this area - we have done a very good job in this regard, and the other is to prevent the Muggles from observing us through remote means."

Helga sat quietly opposite Les, wanting to hear his opinion.

In Helga's opinion, Salazar, who had read a lot of books, knew more about Muggles than she did, so he would be more professional than herself in how to better hide in Hogwarts.

"Muggles have many means of remote observation, satellites are just one of them, but after summarizing them, it seems to be nothing more than light, heat and sound.

Light. Whether we see with our naked eyes or through a telescope, we all rely on light.

Heat is detected by a special instrument. Helga, you see, the temperature of our body is very different from the temperature of the fireplace, and also different from the surrounding environment. This difference will be detected by the machine developed by Muggles, so as to determine where there are people and fires in the room.

Sound can also be used to detect objects. Muggles call it sonar and radar, which seems to be inspired by bats.

I think if we take action in these three aspects, we can effectively hide Hogwarts."

Helga blinked: She only understood a small part of what Salazar said. But it seemed that as long as a wizard awakened the fields of [sound], [light], and [heat], Hogwarts could be perfectly hidden?

Unfortunately, neither he nor Salazar's domains had much to do with these three aspects. Godric did have something to do with light and heat, but he didn't know where he had gone, and he couldn't even be sure if he was still alive. Only Rowena seemed to be able to play a role in [Sound].

"You're right, but we're not completely out of options." After listening to Helga's ideas, Rice also expressed his own ideas.

"We can expand the range of the Muggle Repelling Spell, so that they leave before they can get close to Hogwarts. Then, Helga, you can think of a way to change the terrain near the school so that people walking in this area will unconsciously increase their physical consumption. This will discourage as many Muggles as possible from fleeing to the vicinity. As for the sight from the sky, I can form a large cloud of fog over the school. The thick fog is enough to block the Muggles' detection methods."

Hearing the second half, Helga's eyebrows knitted together.

"So, there will be no sunshine over the school in the future?" Helga felt very depressed when she thought that in order to hide, the sky above Hogwarts would always be gray.

Who can stand it if it's foggy and cloudy every day?

Les:…

You have so many things to do!

But this does seem to be just a stopgap measure.

"Then should we create a super-large magic circle to cover the school, so that the Muggles outside can only observe the illusion created by magic, and the weather inside the magic circle is normal?"

Helga's eyes lit up: This is a good idea!

Update is coming~

I wish you all good luck in the college entrance examination. When I was in school, the exam lasted two days. I wonder if you have finished it now?
