Hiding in Hogwarts as a professor

"I think you have some knowledge of Dementors on your own, so I will only explain some things that you may not know."

"If you have any questions, just read the book after class. After all, this is an extracurricular knowledge class."

Under the horrified gazes of the students, Tver took a big step forward and was only less than half a foot away from the Dementor. Even closer, he could already be said to be standing side by side.

But he was not affected in any way, and he still had a standard professor's smile on his face.

The dementors didn't seem to notice, there was no movement, and the students were more lively than they were now when they first came around.

"The dementor actually has no facial features, um..." He lifted its hood with his wand in disgust, revealing the horrifying hollow mouth.

Speaking of which, he still had to learn how to suck out souls with this mouth.

Thinking of this, he felt a chill.

"It should be said that they only have one mouth, so they are blind and deaf, and do not rely on their eyes to search for prey."

"Then what do they rely on? The dementors accurately ran onto the Quidditch field during the last game." George asked angrily.

If it hadn't been for the Dementors, the best broom in the Gryffindor team wouldn't have been reduced to pieces!

"It's emotion!"

Tweel put a little silver light on the wand, just like teasing a cat with a cat teasing stick, attracting the dementors to poke their heads in.

"Dementors rely on happy emotions to feed. When such emotions appear within their range of perception, they can follow the taste."

"So, don't think that your disguise can fool the dementors. This is meaningless."

"Only someone like me, who closes off his emotions, can stand next to the dementors arrogantly even without pretending."

Only then did the students notice that the professor's smile was as stiff as a puppet's, and his eyes became very calm, neither warm nor indifferent.

To be honest, this kind of smiling face scares them more than the dementors...

This is a little trick Tver practiced using Boggart to help him block his emotions.

It can be regarded as another kind of Occlumency, or an advanced effect of Occlumency.

It's just that the effect seems a bit strange.

So he didn't last long before he stepped away from the dementors again.

Even if his heart is strong enough to resist the negative emotions caused by the dementors, he doesn't want to bear the feeling of being in a bad mood.

"What does this way of perception remind you of?"

Tver blinked smartly, making the students feel a little better.

"Boggart." Cedric answered immediately.

"Yes, Dementors and Boggarts both belong to non-existence, but they are completely different."

Tver's expression turned serious.

"Actually, from my understanding, dementors are not eating happiness. If you have understood the concept of black holes, you will know that what they want to do is to swallow up positive emotions such as happiness and excitement."

"They are like the dark side of the world, and our happiness is actually a weapon against them."

"It's kind of like water and fire, restraining each other."

"If our happy emotions are not strong enough, they will be suppressed by the dementors, but when our emotions are strong, we can destroy them in turn."

"So, if you feel despair, don't worry, stand up bravely and defeat them with happy emotions!"

"And this is the principle of the Patronus Charm."

The students nodded thoughtfully.

When they learned that dementors were surrounding the school, they checked a lot of information, and naturally they knew about the Patronus Charm.

The description in the book basically says that you need strong positive emotions, but it doesn’t say exactly what kind of positive emotions you need.

Now with the professor's explanation and from the contact with the dementors.

What they need is positive energy that can rival the negative emotions emitted by the dementors.

"Does that mean that as long as our positive emotions are strong enough, we can destroy a lot of Dementors?" Cedric suddenly asked.

"Please, we haven't even been able to summon the patron saint yet, and you want to do it to this extent. Isn't that fanciful?"

George changed from his previous confident look and began to ridicule Cedric.

"If the dementors really attack, let alone positive emotions, it's better if we don't pee our pants in fear."

Fred pointed at the dementor with some fear.

"If I were to face this Dementor alone, I would be too scared to move."

"Yes, this is what I want to remind you. If you encounter a group of dementors, unless your positive emotions are strong enough, using the patron saint to open an escape route is the best way to use it."

Tver said solemnly.

After all, not everyone is a protagonist like Harry. The Patronus they released can be considered qualified if they can defeat the Dementors alone.

"Ah, can't you cast spells continuously?" Davis asked in surprise.

"No, even if your magic power is sufficient, the influence of the dementors will weaken your positive emotions until there is no way to release the patron saint."

Twil waved his wand, changing the dementor's restraints into a circle, and then gradually expanded into a hemisphere.

This hemisphere was twenty feet in diameter, and was surrounded by a pleasant silvery light.

"Next, you have to enter this ball one by one and use the Patronus Charm to deal with the Dementors head-on."

"If successful, you will be allowed to come out."

Tver opened a small opening in the hemisphere and waited for the Dementor's challenger to appear.

"Professor," George raised his hand tremblingly, "What if it fails?"

"You will die." Tver smiled kindly.

The students' eager smiles suddenly froze.

"Okay, who of you wants to go in first?"

The students stepped back in unison, and George, Fred, and Davis pushed Cedric neatly and brought him in front of the professor.

"Then it's just you four, come in." Tver pointed to the four of them standing in front in a funny way.

∑(O_O;)

The three Georges looked at each other and found that they were all dumbfounded.

"Come on, I'm already waiting for you at the door."

Cedric was still a little resentful at first, but seeing this scene, he couldn't help but wave to them with gloating.

The professor has been at the school for two and a half years, and he has a good understanding of the professor.

Although there are often dangerous parts in the classroom, the professors take adequate protective measures.

How could they really be allowed to die in there? It would be possible for them to suffer a little.
