Hogwarts starts with stealing power.

Bellatrix stared fiercely at the pool of black blood on the ground, cursing non-stop: "Damn it, damn it! Who is cursing me in secret!!"

Her body was shaking, and her body's reaction made her feel uncomfortable, and she still wanted to vomit.

But at the moment when she was about to vomit, she swallowed it back with great effort.

She crawled on the ground, trying to collect the black bugs mixed in the blood, and swallowed them back bit by bit with her tongue.

"The master's blessing cannot be wasted. I am his most loyal believer..."

Suddenly, Bellatrix looked up and forward, a phantom appeared in her eyes, and a passage to the evil world slowly opened in front of her.

This was a dark blue passage with intricate patterns. As she walked forward, the passage began to twist and extend in strange ways.

Bellatrix stood in front of the dark blue passage door, and seemed to hear the dark and hoarse voice of her master.

"Open it, Bella, my most loyal servant."

"Bella, open her…."

Bella slowly raised her hand, and when she was about to put it on the door, the voice of the guard suddenly became harsh, making her eyes clear again, and her confused look became extremely irritated.

But after a few seconds, she put her hand on it without hesitation and opened the door of the passage.

In an instant, an extremely light and full force came from the world of the evil god, and was transmitted through the hands, quickly restoring vitality to Bella's old and withered body.

Bellatrix laughed crazily and muttered: "This must be a blessing from the master, it must be like this..."

She didn't notice that the pupils in her eyes seemed to turn into a bright red color, as if they could drip down at any time. These were no longer the pupils that a normal human could have.

And behind her, a pair of invisible black wings were faintly visible.

These wings have no feathers and are not as beautiful as everyone imagines. They are like withered vines, with only a skeleton supporting them, and some pieces are missing.

Once one sees it, one would want to wipe it away, as if it were a gathering of some disgusting and evil things.

At the same time, the "sound guard" deployed in this village also quickly shattered and was completely destroyed and silenced.

Bellatrix turned to look at one of the devices that was smoking and suddenly burst into laughter.

"This must be the guidance given by the master. It's fun, so fun..."
-
The Aurors Department of the British Ministry of Magic suddenly received a warning.

"What happened? Is the door broken?"

An Auror went to the central console to check, and soon said: "The voice guard we deployed in the southern Biss village was suddenly attacked by some kind of force and was destroyed on a large scale.

Judging from the time when the nodes disappeared, the voice guards in the village over there all failed at the same time, and it seems that some powerful force has descended."

"Biss village?"

An Auror thought of something and asked in surprise, "I remember that village was sparsely populated and very vast. I was the one who deployed the sound guards there, at least 50 of them. How could they all be destroyed at the same time?"

The Auror who was investigating nodded: "Yes, they all failed at the same time."

The head of the Auror Department made a prompt decision: "Immediately activate the nearest portkey and send a team, no, a group to investigate."

The Aurors act quickly, and the British Ministry of Magic has placed multiple portkeys throughout the UK, allowing them to quickly reach any corner.

There are also many criss-crossing magic fireplaces in the UK, which are under surveillance at all times. Only those "black routes" that are quietly opened can avoid supervision.

However, this type of black household is not stable and is very likely to be transmitted into the shock of the space storm during transmission.

Currently, the technology to maintain space stability is exclusively controlled by the British Ministry of Magic, and only a small number of people understand this technology.

Even if we knew it, building a channel would require a lot of rare resources.

Every purchase of these resources is recorded.

The Ministry of Magic also releases a batch of resources on the black market every year and sells them to unknown wizards at extremely high prices.

It seems like embezzlement, but in fact, what they gave are inferior products among the best ones, with poor quality. Even if the channel is built, it is very unstable and cannot be used more than five times.

Therefore, the Ministry of Magic is still very tolerant of this, and sometimes they even take charge of this business themselves.

Less than half an hour.

A group of Aurors arrived at the village of Biss.

As soon as they arrived, they noticed something and looked towards the village which was one thousand meters away as the crow flies.

Even from a distance, they could still feel the evil aura emanating from the village.

An Auror said solemnly: "With such a strong aura, could it be that a high-level weirdness has descended upon the village?"

Another Auror shook his head: "It's impossible to tell. We have to enter the village."

The group of Aurors observed carefully and walked into the village cautiously.

When they arrived at the center of the village, they suddenly stopped and were all shocked!

I saw a pit nearly 10 meters deep in front of me, and the soil at the edge of the pit showed signs of being burned to a charred color.

In the very center of the cave, the soil was cut into messy traces, as if some giant creature was sharpening its claws, but these traces disappeared at five meters.

The Auror quickly concluded: "This is definitely a high-level weirdness. I don't know how it came to the wizarding world!"

An Auror asked: "It left such a big mark, could it be the real body?"

Another Auror denied it, "It's impossible. If it was a real body, how come the trace only stayed in this hollow and disappeared before reaching the edge? How did it leave?"

Another Auror said, "I remember that the strange creatures have various sizes and abilities. Maybe it deliberately reduced its size?"

"Couldn't it be that the spirit possessed a Muggle or wizard? Look at these footprints, they look very much like human footprints to me." An Auror discovered a new clue.

Others went to observe, "From the distance from the front toe to the back toe, and the overall outline, this should be a female footprint."

The leader of this group said, "Let's go check inside the village first to see if there are any survivors. If it is really a high-level weirdness, I'm afraid everyone inside is in great danger."

After checking, the Aurors looked solemn, but they all felt relieved in their hearts.

Fortunately, today is the market day in the village. Most of the young and middle-aged people have left the village, and only some elderly people with limited mobility remain in the village.

However, these old men were all dead at the moment the mysterious force arrived, and their body structures were destroyed in an instant by some force.

But judging from his expression, he left peacefully.

The Auror thought about it, reinstalled the voice guard in the village, and then returned to the Ministry of Magic through the portkey. After they left, a huge black shadow slowly appeared above the village.

It spread its ugly, broken wings. Even though the sun was shining brightly, it made people feel a chill for no reason.

……

Lin Xia arrived at Hagrid's cabin on time for class.

In this Care of Magical Creatures class, Hagrid specifically asked them to go and do an investigation, and gave them a hint - they were going to learn about insects related to wisdom.

The young wizards looked up a lot of information and had already started a heated discussion before Hagrid arrived.

"Since it is related to wisdom, it must be a wise insect. From the name, we can tell that it is related to wisdom!"

"No, you definitely haven't researched the data on intelligent insects. This kind of insect is too stupid and can easily starve itself to death, so people named it the intelligent insect, hoping that it can evolve to be smarter in the future."

"I think Hagrid wants to teach us how to plant the Tree of Wisdom. I heard that the fruit on the Tree of Wisdom is called the Fruit of Wisdom, which can temporarily improve the intelligence of wizards."

"But this is just a rumor. There is no definite research to show that wisdom fruit can really improve intelligence."

“I have also researched this. The information says that after taking the fruit of wisdom, one will feel that the brain’s thinking becomes faster and one can think clearly about many problems that one did not understand before.

But Hagrid said that he was studying insects, not trees. The wisdom tree and wisdom fruit are not ordinary goods. Can Hagrid come up with so many?"

Ron and Harry listened to the discussion of other young wizards. They also looked up some information, which was similar to what these young wizards discussed.

Harry asked, "Hermione, have you found out?"

Hermione nodded, "Of course, I think Hagrid is going to talk about the Billywig worm.

This insect has a jade-like green luster and is very small, smaller than a mosquito. Its wings vibrate at a high frequency and very quickly, so it can fly far away in an instant.

They are hidden in the Muggle world and are not discovered by Muggles.

Once a wizard captured them and believed that the high-frequency vibrations in their wings could bring inspiration to thinking.

So a few decades ago, there was a wave of research on using the wings of the Billywig insect to put one's mind into a high-frequency state."

At this point, Hermione paused and said hesitantly, "But the final result of this study is not very good."

Draco added: "I know this research is flourishing in Australia, and Australian wizards are very keen on catching Billywig worms.

There is a thin stinger at the bottom of its body, and anyone stung by a Billywig will feel dizzy and then float up."

Ron asked curiously, "What does this have to do with wisdom?"

"Ravenclaw's Diadem." Lin Xia's voice came, and she came to them with the sound of ringing bells.

Before Hagrid appeared, she said quickly, "There was a wizard called Lovegood who tried to recreate the Ravenclaw diadem using the wings of a billywig.

He thought these bug wings could induce a 'higher state of mind', but he obviously failed."

Hermione asked: "I also found this information, but I am confused. Why do you think he failed? Maybe he has already invented it?"

Harry and Ron also wanted to ask this question and looked at Lin Xia.

This time, Lin Xia didn't need to answer, Draco could give the answer.

"Because Lovegood is a noble, he announced with great fanfare that he would replicate the Ravenclaw diadem. Once it is successfully made, there is no way he would keep it secret. This is a supreme honor.

He has always wanted to apply to join the Researchers' Association, and he regards 'Resetting the Ravenclaw Crown' as a stepping stone to join the association. For honor and benefit, he will not hide it. "

Harry listened for a long time and couldn't help asking: "So, what exactly is the Ravenclaw crown? Is this crown very powerful?"

Lin Xia was about to speak when suddenly, Hagrid's loud voice rang out: "Ladies and gentlemen, welcome to the Care of Magical Creatures class!

I'm Hagrid, your magical creatures professor. Did you miss me?"

Hagrid spoke his carefully prepared opening remarks in a rhythmic tone.

He felt a little uneasy.

The effect of having the little wizard take care of the Flobberworm in the last class was not good, and he was afraid that the little wizard would lose his enthusiasm for studying magical creatures.

But it was obvious that the little wizard had forgotten the unpleasantness of the previous class. He warmly welcomed Hagrid's appearance and clapped his hands enthusiastically.

They can't wait to study bugs related to intelligence!

Seeing this, Hagrid didn't keep the secret and took out a cage half a person's length from behind him. The cage was covered with transparent glass.

The young wizards came forward one by one to check it out, following Hagrid's explanation.

“These are Billywig worms, and although they are quietly staying in the cage, you won’t be able to see them once they are released.

They often hide among people, and also like forests and high clouds. Even wizards cannot find them due to the high-speed vibration of their wings.

It is often because of being stung. Yes, it is what you see, the tail sting at the back of the insect. When being stung, there is a stinging sensation, which makes people aware of this insect.

The reason why it is related to wisdom is that its wings may allow you to enter a 'higher state of mind', and some people use their wings for research."

Hagrid stressed: "But this kind of research is very risky. If you are not a professional, please don't try it. Some wizards deliberately induce Billywig bugs to sting him, which can easily cause allergies.

Once stung by an insect, you will float in the air, and if you fall into an allergic state, it will cause death.

These bugs are common in Australia and have caused several deaths among wizards.”

Hermione raised her hand high, and Hagrid happily called on her: "Hermione, what's your question?"

Hermione asked, "Professor Hagrid, so can Billywig worms really improve our intelligence?"

Hagrid smiled and said, "That's a good question. I'd love to answer it, but I don't know."

The young wizard was surprised, "Don't know?"

Hagrid nodded. "Yes, although some wizards have done research on intelligence, they have not been successful. It's just that the mainstream voice in the wizarding world still believes that these bugs are related to intelligence."

He rambled on, "I think the reason for this view is mostly because the wings of these insects look like a certain material on the Ravenclaw crown, which makes some wizards believe it unwaveringly."

Hermione raised her hand again: "Professor, what exactly is the Ravenclaw diadem?"

Hagrid: "Extraordinary wisdom is the greatest wealth of mankind. I believe you have all heard this saying. Legend has it that the crown is enchanted to increase the wisdom of the wearer." (End of this chapter)
