Hogwarts starts with stealing power.

After these outstanding students left, Ron looked at Lin Xia and asked impatiently:

"Lin Xia, what exactly is this voice protection you invented?
I've been meaning to ask you this ever since Professor McGonagall announced the type of your paper."

Lin Xia said calmly: "This is a musical note that can drive away the weirdness. You can treat it as a talisman that is made of sound. It has the same function as an ordinary talisman."

Harry said, "But the sound protection only needs to hear the sound to play a protective effect, while the protection amulet needs to be worn on the body. The transmission methods of the two are still very different."

Draco concealed his shock and couldn't help asking, "Are you sure that the 'voice protection' can achieve the same effect as the protection charm? I'm not questioning this thing, this is really incredible!"

He had never heard of a magical item that could use sound to protect him, but he had heard of several magical items that could use sound to attack.

Moreover, the sound of "audio protection" can play the role of expelling weirdness, which is difficult to achieve in theory.

Generally speaking, strange objects play a protective role and are used to protect oneself, and are difficult to expel strange things.

After all, the wizarding world has not delved deeply into those strange phenomena, and does not know how they are formed or how they disappear.

Such an effect can be achieved with just a piece of music, which somewhat overturns Draco's understanding of strange objects.

Even if it is an item similar to a talisman, it will not seem so abrupt.

But Lin Xia said confidently: "This is what I discovered through research at the Researchers Association, and the results have been certified by the association.

The association notified the Ministries of Magic of various countries long ago, hoping to promote this thing as much as possible.

The British Ministry of Magic was the first to agree. If nothing unexpected happens, the melody of "Voice Guardian" has already been promoted in some remote magic villages in the UK."
-
In a remote mountain village in Gurnhill, England.

This is a village where wizards and Muggles live together. Due to its remote location, the people here only go out once a month to purchase supplies.

But because it is remote enough, some things can be covered up. In the basement of this village, there is actually a laboratory dedicated to studying the weird.

The wizards in this village are not ordinary wizards. They are elite Aurors transferred from all over the place, or some well-known scholars.

They lived with Muggles and lived here under assumed names for at least three years, just to study and understand the formation of the weirdness.

The wizard world and the evil god world actually merged little by little many years ago.

But it was not so serious at that time. Occasionally, some supernatural events would break out in some places, but people didn't pay attention to it. They thought that a wizard was doing experiments in a Muggle village and didn't handle it properly, which caused panic among the villagers.

It was not until a wizard conducted an in-depth investigation into a supernatural event that he discovered that it had nothing to do with wizards.

Those things just suddenly appeared there, no one knew where they came from, and no one knew where they disappeared.

Later, as the wizards' investigation deepened, they gradually discovered that the supernatural things that suddenly appeared were not unique to the wizarding world, but rather seemed like visitors from another world.

At first, wizards called these things aliens.

As the research and investigation deepened, the wizarding world studied those things more and more deeply, and even encountered some humanoid creatures that could speak and communicated with them, only to find out that they came from the world of evil gods.

That is a world completely different from the wizarding world, with a different set of operating rules!
The rules there are all disordered, and humans live at the bottom, being exploited in all kinds of weird ways.

Those things that wizards find very strange are everywhere in the world of evil gods.

There are strange deaths every day, and strange births every day.

There are strong and weak weirdness. Strong weirdness can raze a city to the ground, while weak weirdness can only cause trouble for the lower-class humans.

It is said that there is also a promotion mechanism within the weirdness, but the wizards are not clear about the conditions for promotion. It seems to be related to fear and faith.

Wizards call the act of bringing the weirdness of the evil god's world to the wizard world "smuggling".

At the beginning, strange smuggling cases were not frequent, perhaps only happening once every six months.

But later on, we could make some discoveries every one or two months.

Moreover, the strange things they discovered were all those with greater impacts. Some of the ones with weaker impacts might not even encounter wizards and would disappear on their own.

With this in mind, the wizarding world has set up some special departments to deal with the weird, and they do not investigate in the open, but instead investigate in secret.

At that time, the evil god world and the wizard world were already communicating frequently, but the weird was ultimately an outsider and could not stay in the wizard world for long.

Later, the evil god world seemed to discover that the wizard world had more humans and sufficient faith, so it began to covet the wizard world.

Once those stowaways appear, they will mislead people and start wars again and again in the Muggle world.

Originally, the weirdness only bewitched Muggles, and wizards didn't take it seriously.

But later on, those strange methods became more and more powerful, and even wizards were bewitched.

Once a wizard is bewitched, the impact is enormous. It is no exaggeration to say that all lives are devastated, and the population also decreases rapidly during that period.

When the number was reduced to a certain level, the wizard finally realized something was wrong and began to be wary of strange creatures, killing them one by one as they appeared.

Because during that period, the wizard world and the evil god world frequently launched wars and communicated too closely, and soon, a place appeared in the wizard world that overlapped with the evil god world. The wizards called it the "boundary point."

There are still many wizards who suppress the weirdness in the boundary points and do not allow the weirdness to sneak in.

Both worlds influence each other.

The evil god world had suffered several defeats, and the culture there had also been infected and impacted by the wizard world. Many humans had rebelled and fought for their rights, so that humans would believe in themselves instead of the evil god.

But the wizarding world has also suffered defeats.

The biggest defeat was that their knowledge was invaded by the evil god's world. Every wizard who wanted to read the forbidden book and gain more powerful power would be invaded by the evil god's power and tempted to fall.

There are many low-level wizards with great potential, and even high-level wizards may not be able to resist this kind of corruption.

The most serious of them all was Voldemort.

When Voldemort read the forbidden book, he sided with the evil god and developed his own believers. Even though he had been killed once, he is still creating panic.

"How is it going? Has that strange power weakened?"

In the underground laboratory, a wizard asked seriously.

Another wizard carefully observed the data, then looked at the weirdness imprisoned in the center, and slowly shook his head.

"No, the power of 'Voice Guardian' has no effect on intermediate-level weirdness."

Another wizard asked: "What about the impact on Muggles?"

The wizard who was observing the data shook his head again. "Almost no effect. You may feel a little irritated when you first listen to it. I call it 'withdrawal reaction'.

Although we didn't let the weirdness come into contact with them, the weirdness is underground. Even if we keep it well, over time, the magnetic field will overflow and will have some physical and psychological effects on Muggles. This effect is very subtle and will not erupt under normal circumstances, but it will erupt and sweep in a sudden under certain circumstances, which can quickly destroy the body and mind.

Later, the Muggles got used to hearing it and even felt happy.

Several Muggles came to ask me what the music was that was playing outside every day. They wanted to buy CDs to listen to. They felt that under the influence of this music, their moods became much calmer. "

As if thinking of something, the wizard who was observing suddenly turned around and asked, "By the way, do you know the Great Compassion Mantra?"

"The Great Compassion Mantra?"

The other wizards looked at each other in confusion. They had never heard of this word before and it sounded very unfamiliar.

The observer was not surprised to see this, as he had no idea what the word was when he heard it from a Muggle.

“It is said that this is a very magical scripture that came from the far east and has the effect of saving the dead.

When they listen to music outside, they feel like they are listening to the Great Compassion Mantra. Some people even think that this piece of music comes from the Great Compassion Mantra.

There was a Muggle who had a relative in the East. He specially asked his relative to send him a tape with the Great Compassion Mantra recorded on it. It traveled across the ocean and finally arrived here. But after it was played, it was discovered that it was completely different from what was heard. "

A wizard was moved and asked, "Have you heard of the Great Compassion Mantra? Does it have any effect on the weirdness?"

The observer nodded and said, "After hearing what they said, I went to listen out of curiosity.

It has no effect on the weirdness, it's just a normal piece of music, very different from 'Voice Guardian', but for some believers, this song has a deep faith."

"So the test results show that 'Voice Guardian' can only make ordinary wizards and Muggles feel calmer?"

The researcher said: "You haven't noticed that since the audio guard was played, the strange noises have become much smaller, and there are almost no strange events happening outside.

I suspect this music also has the effect of dispelling the weirdness, but it will take longer to observe. "
-
At the same time, in a remote mountain village in northern England.

It was night time, and the sound of "audio guard" kept echoing in the quiet village, breaking the silence and adding a bit of humanity to the quiet village.

There are more than thirty households in this village, most of them are wizards, with a small number of Muggles living together.

Those Muggles are all related to wizards by blood and know about the wizarding world.

A week has passed since the installation of 'Sound Guardian'.

At first, the sound was quite annoying, but now everyone seems to be used to it, and many people fall asleep to the music.

Sometimes I can't hear during the day and feel uncomfortable.

Some wizards in this village were once bewitched by something strange and had to rely on conservative treatment with drugs, for fear that their minds would be disturbed if they became emotionally excited, so they came to the village to cultivate themselves.

Recently, a wizard replaced the treatment medicine with cold pills. For the first time, he felt his mind was extremely clear and he could think about things very smoothly.

While his mind was clear, he thought about why he had been bewitched by the evil god's whispering.

After thinking about it, I finally want to pursue a higher level of power.

After arriving at the village, he restrained himself from using magic, but was occasionally attacked by the evil god's whispers. That was because deep down in his heart, he still wanted to pursue more powerful power.

With the help of Leng Wan, the wizard calmly and clearly analyzes what he wants and faces his desires honestly.

He decided that he couldn't run away any longer, and he had to take a formal step forward!
Along with the 'vocal guarding', he consulted with several other wizards who were watching over them.

The wizards discussed for a few days and decided to send the wizard to a secret institution for study.

Before leaving, the wizard supervising them advised him: "You are still at a low level of invasion and can control yourself.

If you enter that secret organization, you will have to face the evil god's whispers all the time, and you will have to fight against weirdness...

Although you will become stronger, it will also likely become more painful. Have you decided?"

The wizard said confidently: "I will go. Only by facing my desire honestly and not running away from it can I defeat it!"

The wizard who was supervising him watched as the wizard was taken away by other wizards who arrived.

Only after his figure disappeared did the wizards take out a notebook and record the various reactions of the wizards after taking the "Voice Guardian" and the cold pills together.

"This is the third person who has proposed to leave since the deployment of the Voice Guardian, all in pursuit of greater power.

They haven't made up their minds so quickly after taking the cold pills alone, so does 'voice protection' still have the effect of making people realize their true nature?"

Another wizard replied: "I don't know, but we can observe again. The effect of these two things combined is far more than 1+1=2. It is obviously greater than 2 or even greater than 3."

A wizard couldn't help but sigh: "I don't know who developed these two things, they are really amazing, what's wrong with his brain?"
-
In a remote mountain village in eastern France.

The villagers looked at the Aurors from the Ministry of Magic curiously, finding it very strange to assemble a small object in the open space.

Some wizards went to ask: "Didn't we just install the radio last year? Why do we have to replace it this year?"

When not facing the most vicious criminals, the Auror was still very helpful and replied: "This is not a broadcast, but a 'voice protection'. You can think of it as a large protection amulet.

It protects you by continuously playing sounds, and it should also have a slight effect of repelling weirdness."

The wizards who live here are very old.

As they get older, they know a lot of things they need to know. These wizards know about the evil world and the strange invasion.

Their expressions changed involuntarily. It was actually possible to expel the weirdness? !

When did the Ministry of Magic get such a magical thing?

A wizard walked around the speaker several times, but it didn't look like a strange object no matter how he looked at it.

The Auror shrugged and said, "It was developed by the Researchers' Association. There are many crazy researchers there, and many inventions are made every day.

The association specifically issued a notice, hoping that the Ministry of Magic of each country could select a few pilot projects for promotion and trial.

We have just started using it here, but the UK has already been using it for half a month, and it is said that the results are very good, so our Ministry of Magic is also interested."

“It was actually discovered by the Researchers Association?”

When the other wizards heard this name, they felt relieved.

"Since it was researched by the association, it must be effective."

"Yes, the association never deceives us." (End of this chapter)
