Hogwarts starts with stealing power.

Because of the endorsement of the Researchers Association, the installation of the "Audio Guardian" in France went smoothly.

A week after the installation, the villagers became accustomed to listening to the sound.

A researcher came to conduct an investigation and found that some villagers would feel uncomfortable if they did not listen for a day.

The researcher specifically wrote in the survey report: [Voice Guardian may be addictive]

I thought life in the village would be peaceful until one day, a strange creature with red spots all over its body descended on the village.

It did not choose to be possessed by a Muggle or wizard, as this would consume too much energy for it. At first, it appeared as a ball of mud with red spots.

It lurks quietly in the village, trying to absorb the negative emotions of the village and thrive.

Once it grows to a certain size, it can choose a host at will to replace it.

Because he did not approach the village at the beginning, but was lurking in the woods in front of the village, Guiyi did not suffer any harm and did not feel anything was wrong.

The weirdness of the evil god's world has summed up a set of smuggling experience, and it is based on this experience to allow itself to better integrate.

When the strange thing felt that it had understood most of the situation, and its energy accumulation was a bit slow, it decided to quietly crawl into the village in the dead of night.

Before, it was far away from the village and did not hear any movement from the village. It could only see that there were quite a lot of people in the village, with people coming in and out every day.

But when it arrived at the village and heard the voice of "voice guarding", it couldn't help feeling extremely uncomfortable all over!
There seemed to be a voice in his heart telling him to stay away! Stay away quickly! Don't enter!

The creature quickly crawled away from the village, but its body had already been exposed to the sound.

When it came to its senses and wanted to retreat, it was too late!
These voices kept echoing in its ears, turning into waves of invisible attacks that quickly destroyed its spiritual will.

It is obviously the weirdness that can disrupt the human spirit and seduce humans to degenerate, but under this voice, the weirdness is out of control.

who am I?
Who am I?
Am I human?

I used to be human!

I'm not weird!
Why do I have a weird body?

As the questions came one after another, Weird's thoughts became extremely confused.

Sometimes I feel like I am a person, sometimes I feel like I am a disordered rule, sometimes I feel like it can’t move like this, sometimes I feel like it shouldn’t exist…

Under the influence of the sound guardian, its thoughts were extremely confused.

After a few tenths of a second, the ball of mud with red spots finally collapsed and exploded due to the interference of the sound guard!
It was like a mass of sticky magma scattered on the ground of the village. The wet mucus gradually evaporated and dried, and the mud spots printed on the ground gradually disappeared, and finally turned into wisps of dust.

As long as the wind blows gently, it will dissipate between heaven and earth.

But the strange corpse was not greeted by the wind, but by researchers in wizard robes one after another.

With solemn expressions, they collected the dust left behind by the strange deaths, occasionally talking to each other.

"I originally thought it only had the effect of expelling weird things, but I didn't expect it to be able to kill them. This is incredible. Who invented it?"

"The news I heard is that this was invented by a wizard in the UK. The Researchers Association strongly recommends it. It is also rumored that the wizard is very young. It seems that he will hold a paper release conference at the British Ministry of Magic soon."

"It's a pity that I can't take a leave, otherwise I would definitely fly over to see it!"

"When this group of weird things entered the village, I almost couldn't help but want to take action. The sound protection is very powerful and is very effective against low-level weird things."

"Yes, this low-level weirdness is not as vigilant as the mid-level weirdness. If it is a little further away, it will not be able to hear the sound of the guard. When it gets closer and hears it, it will also fall into the net."

A researcher wrote an observation report: [Sound protection has a killing effect on low-level weirdness, an expulsion effect on mid-level weirdness, and an unknown effect on high-level weirdness]

……

As observation reports were sent to the Ministry of Magic of various countries, they were sorted out by the Ministry of Magic and then passed on to the Researchers' Association.

The Researchers Association used the Sage's Eye to compile all the data, produced a more comprehensive analysis report, and then compiled it into a book and distributed it to the Ministry of Magic of various countries.

With the release of this analysis report, the Ministries of Magic in various countries have a deeper understanding of "Voice Guardian".

There were only four Ministries of Magic that applied for the trial in the first batch. At that time, everyone was just giving face to the Researchers Association and did not expect that the sound protection would have any effect.

Now that the results are out, the number of Ministries of Magic that have applied for the second batch is as high as 2!
Especially those remote countries, they are very interested in the role of sound protection in expelling weirdness and eliminating low-level weirdness.

This saves countless Aurors!

They live in a remote area, where it's difficult to train talent. Even if they do manage to train one, they just treat the person like a dog.

Not only that, patrols are often not timely, and strange incidents break out in the village from time to time, forcing the Ministry of Magic there to spend money to hire Aurors from other countries.

With audio protection, they can save a lot of money!

After reading the report, some researchers also received an invitation from the British Ministry of Magic, and showed great interest in the paper release conference held by Lin Xia, the inventor of the audible guardian.

Privately, these scholars have gathered together for several rounds of discussions on the invention of sound guardian.

Others who have good relations with the British Ministry of Magic even sent letters directly to inquire about the specific date of the meeting.

What's more, Dumbledore was contacted directly.
-
Dumbledore is working at the Ministry of Magic.

His expression moved slightly, as if he had received some kind of magical signal. He did not wave his wand, but just raised his head and looked somewhere with his deep blue eyes.

After a while, a white cloud appeared before his eyes.

Dumbledore nodded slightly, and the cloud quickly turned into a sound. As the volume grew, the cloud began to rise and fall, expanding and shrinking.

"Dumbledore, I heard that a talented person has appeared in your British Ministry of Magic. She is the one who invented the voice guardian. Her name is Lin Xia, and she is a little witch."

The voice coming from the clouds sounded a little old, but full of energy, and one could tell at once that he was an old man in good spirits.

Dumbledore couldn't help but raise an eyebrow: "Nicol, I thought you were not interested in the sound ward."

He suddenly smiled and said, "Why did you wait until now to ask me this? You are late. Many people have asked me this question in the past few days."

"Hey, man, you have to take care of the reaction speed of an old man like me. I just finished a 10-year-long research. As soon as I got the news, I came to ask you immediately!"

Dumbledore asked, "How is your research going?"

Nico sighed, sounding troubled. "No, there's still one step left. The effect on high-level weirdness is too weak. If I use it to deal with mid-level weirdness, the cost is too high. It's not cost-effective."

He changed the subject and said, "The Sound Guardian has given me a lot of inspiration. I want to talk to the inventor."

Dumbledore smiled and said, "Of course, you should set off now. It will take some time to get from your laboratory to the UK. If I remember correctly, you should reserve some time to enjoy the scenery along the way."

Nico: "Haha, Dumbledore, you really understand me. I'll leave now.

Well, I want to prepare a small gift for little Lin Xia, do you have any suggestions?"

Dumbledore said softly, "You don't know who her teacher is yet, it's Babling." "Babling?"

Nico said in surprise, "I didn't expect that even the old witch Babu Ling would accept a disciple. The outside world is changing so fast. I should go out for a walk.

Well, since she is Babel's student, she must be very talented in ancient magic words. Her standards for accepting disciples are much higher than mine... I think I probably know what gift to give Lin Xia."

The glowing cloud disappeared before Dumbledore's eyes, leaving no trace of dust behind.

Dumbledore stood up and walked to the window.

The place where he was was the highest point in the Ministry of Magic and also the highest point in the whole of Britain. He could overlook the winding mountains, the villages and the criss-crossing lakes.

The world seems to be made up of small cubes that can be erased and reassembled at any time.

Finally, he fixed his sight on a winged terrain; that was Hogwarts.

Dumbledore's eyes became deep and he fell into deep thought.

"Lin Xia, could it be a variable in the divination?
How many surprises can she bring? But Harry is the one that needs to be grasped most. No matter how good the knowledge is, it needs to be protected by force."

……

Here at Hogwarts.

The audio guard has been installed for three days.

During class, the audio guard will not make any sound. When the get out of class is over, the speakers hanging above the pillars will emit melodies.

The sound sounds a bit strange. It is different from the melody of the music, it is out of tune and difficult to hum, but it is okay once you get used to it.

In Ron's words: "This melody has a magical brainwashing flavor, so cool!"

The little wizard was not sure whether the sound protection could drive away the evil.

However, the outstanding students who patrolled at night discovered that during the patrol, after the sound guard music was turned on, the Dementors that had been wandering around the windows would move away from the windows.

This is strange.

One of the top students couldn't help but say, "Dementors are actually afraid of this thing."

"Have you noticed that since the audio guard was activated, the number of unusual movements heard during night patrols has decreased."

Another outstanding student nodded and agreed, "Yes, I would hear some noises in the bathroom when I was patrolling in the early morning every night, and I recorded them, but when the professor went to check, he found nothing.

I never heard anything unusual until the bathrooms had sound guards installed.”

Another outstanding student said: "We still need to pay more attention. Maybe the sound of the sound guard is too loud, so it covered up our discovery of the unusual movement."

As for Lin Xia, after finishing a day's patrol, he returned to the golden cabin and took out the Wizengamot Medal to study it.

Originally she thought it was just an ordinary medal, but during the Defense Against the Dark Arts class, the dark creature Cabba was obviously afraid of the medal and didn't dare to approach her.

At that time, she just thought that this medal might have some kind of powerful aura. Kaba was afraid of this aura, so he didn't dare to approach her.

But as she studied the medal and even held it under a magnifying glass, she discovered it might not be what she thought.

The arrangement structure of this medal is not simple!
Today was another observation. Lin Xia recorded the structures she saw through magnification. She planned to ask Professor Babeling.

Professor Bablin guided her in the direction of magic runes, and the structure she saw was not an alchemical combination, it was not something that could be achieved through alchemy, but rather it was a bit like a magic rune combination.

She wrote down a piece of distorted text - "JSEN", and each one happened to correspond to a basic magic rune.

These characters look like they have been transformed from basic magic runes.

After finishing the research, Lin Xia looked at the box filled with forbidden magic words. In the past half month, the box had been very quiet, and it was already the time she and Tom had agreed on.

But the quieter it was, the more unsettling it made people feel, so Lin Xia did not open it.

She decided to stay idle for a while.

At the same moment, a portrait in a corridor of Hogwarts suddenly twisted spontaneously, opening a passage hidden behind the portrait.

A burst of hurried footsteps came from the dark passage, and then the passage twisted and Bellatrix arrived at Hogwarts.

As soon as she entered, she heard the melody of voice protection, and her expression twisted.

"Damn it, damn it, who put music in school!"

Bellatrix clenched her fists, trying to suppress the urge to return to the tunnel.

Ever since she was warned by Snape, she kept quiet for a while and no longer went in and out of Hogwarts. Instead, she hid in a remote mountain village somewhere in England.

The area is vast and sparsely populated, and beyond the reach of the Ministry of Magic, making it a perfect base for the Death Eaters.

They had already arranged a series of plans, but just the day before yesterday, the village was raided by a bunch of damn Aurors from the Ministry of Magic!

They thought their whereabouts had been exposed, so they quietly hid in the dark and planned to fight the Aurors if all else failed.

With the Death Eaters' abilities, can't they deal with a few Aurors?
It turns out that the Aurors weren't there to arrest them, but to install something in the tree.

The Death Eaters watched and watched, and no one cared.

What changed was that after the Aurors left, the big speakers on the trees began to emit a strange melody, which made them feel unwell, their chests felt stuffy, and their thoughts were confused.

For fear of damaging the loud speaker and attracting the attention of the Ministry of Magic, they had to move to another remote village.

Unexpectedly, a large loudspeaker had been installed in that place a long time ago, playing music in a loop 24 hours a day. The villagers were actually used to it and fell asleep to the music!

But the Death Eaters were very annoyed after hearing this. They could hardly suppress the violence in their hearts and wanted to destroy something to vent their anger.

If it weren't for her master's greater plan, Bellatrix wouldn't have endured it all the time.

Some Death Eaters couldn't stand the sound and ran to destroy the village.

But he didn't expect that once the magic was used, the sound would become even louder, as if it was constantly echoing in his mind, and the magic power would quickly leak out, causing the spell to become unstable.

Let alone 10%, we may not even be able to exert 5% of our strength.

Also, because the Auror was exposed, he was detected by the wizards hiding in the village, and they lost a good man.

"what!!!"

Bellatrix covered her head with her hands and looked towards the direction where the music came from with a ferocious face.

"Whoever installed this thing, I will make him pay with blood!" (End of this chapter)
