"The brain means mind and spirit, and it may not have the power of magic to directly attack physically, but in a sense it represents the evil god itself, the despicable Helbo himself, the most dangerous part. Dumbledore said.

Evan agreed with Dumbledore's statement.

The most terrifying thing about the evil god is the corruption pollution and psychic attacks, through endless whispers, the evil god can cause the attacked to get lost and die in visions, or control those weak-willed creatures, such as the Fallen Centaurs and the Eight-Eyed Spider.

Of course, this is the most obvious characteristic of the evil god, but it is not the whole story.

Their strange creations and formidable bodies are equally despairing, and they are beyond the reach of humans.

"For brains that are good at using psychic powers, ordinary sealing magic obviously can't be applied. That's why Slytherin deliberately chose Azkaban to seal it. From some of the ancient texts left behind by the vampires, we can find some of Slytherin's thoughts, in his original plan, that inaccessible island was located in the depths of the North Sea, far from the mainland, away from wizards, and that there were no creatures on the island, no matter how strong its spiritual power was, it would not affect anyone else. Dumbledore continued, "Slytherin also left the tightest seal there, using the strongest magical power to resist the mental power of that brain. ”

"The strongest magical power?" asked Aven, "Professor, you mean the Twin Snake Staff?"

The strongest magical power against the spiritual power of the evil god's brain, if there is any power that can be called the strongest, Aven can only think of the double snake staff.

Both Gryffindor and Ravenclaw had told him that the Twin Serpent Staff had unimaginable powers.

This power is not something that even a powerful wizard like Salazar Slytherin can use easily.

So, most of the time, he kept the double snake staff on the long table in the principal's office.

Slytherin wasn't worried about losing the staff at all, and most wizards couldn't even touch it.

Evan didn't know what would happen when he touched the twin snake staffs, and the feeling of the two pythons opening their eyes and staring at him would be unforgettable for the rest of his life......

"Oh yes, the Twin Snake Staff is the heart of the magic that Slytherin left behind in Azkaban, the source of that sealed magical power. Dumbledore said, "It has extraordinary magical powers, and I think it's necessary for Slytherin to keep it there, because even with such a strong force, the god's brain is still active, and it makes Dementors, which grow more and more over time." ”

"I don't quite understand what the point of that monster sealed in Azkaban making so many Dementors?"

"Dementors can help it regain its strength, and we all know that it brings despair and sucks away all the happy emotions that wizards believe they feed on. "But it's strange in itself, and no wizard can explain why, and how happiness can be food? It's a very unreasonable thing, it doesn't make sense, doesn't it? Some people blame it on magic, don't study its real cause, and simply take it for granted, but not everything can be explained by magic, and magic is not the unfounded superstition that Muggle heads imagine." It's against common sense for Dementors to absorb happiness and make a living from it, even in the wizarding world, and it's impossible to happen......"

"So, what do those Dementors live on, and what do they absorb pleasure for?"

"For too long, we all mistakenly thought that Dementors were magical creatures with life. As a type of living being, they have to live on something food, but in reality this is not the case, Dementors are non-animate, they are non-living magical creatures that rely on magic to exist, just like these magical portraits on the walls, they rely on magic to survive. ”

There was another chatter all around, and all the principals stopped pretending to be asleep.

They were shocked by Dumbledore's intelligence, which had absolutely upended centuries of understanding of Dementors in the wizarding world, and Evan noticed Phineas Nigelus' pretentious expression, which was rarely seen.

The nature of the evil god's creation is that it is a magical creature and does not need to live on food.

As long as they have enough mana, they can survive.

As for the source of the magic, of course, it comes from the evil gods who make them.

Theoretically, as long as the god has enough power to bear it, it can create an endless army of evil god creators until the entire world is filled, which is not impossible, and the same is true for Dementors.

The wizards tried so many ways to limit the number of this terrible creature, and in the end, they were forced to admit the existence of the Dementors, and make concessions to let them gather in Azkaban, and send the guilty to them, both as a punishment for the criminals and as a so-called food for the Dementors.

Now that I think about it, this decision was simply a joke.

They are not living organisms that reproduce naturally, and all means of restriction will naturally not work.

Even if you use the Patronus to destroy all the Dementors, as long as you don't destroy the brains of the evil gods under Azkaban, after a while, the Dementors will continue to appear, and sending them prisoners only makes them stronger.

"As for sucking out happy emotions or using the Dementor's steady sucking of a soul, they do it all for the sake of the evil god brain under Azkaban, which is able to extract a very beneficial power from these emotions and souls, which is a very complex process, and we can simply understand it as a kind of soul and spirit magic. Dumbledore said, "The brains of the evil gods need these, but they are sealed and confined to Azkaban, so what Dementors does it need to help it gather these powers." ”

"Collect ......"

"Yes, if we study the Dementors, it's not hard to see that their body structure is simple under the cloak, the bodies of these terrible creatures only have a mouth and a stomach to store the happy emotions or souls they absorb, and those rotten flesh skins that connect the two together, and maybe there are things like the Dementor's brain in the flesh skin, but those Dementors are actually secondary, because they only need to follow the commands of the brain that made them most of the time......"
