While Harry was eating chocolate, Lupin left the box with the letter and went to find the driver.

He needed to tell the school what happened on the train, and the driver happened to have an emergency owl at his location.

But that was when he was in school, and I don’t know if it’s still the same now.

After Lupin left, Ron looked at Harry with some concern, "Are you really okay?"

“I feel much better.”

Harry took another bite of chocolate and wiped the cold sweat and rain from his face. He said, "But I don't understand...what happened just now."

“That’s what we’re curious about, too,” said Fred.

Although the feeling brought by the Dementors was very uncomfortable, it was not enough to make people faint. And among the hundreds of students on the whole train, it seemed that Harry was the only one who felt the same way.

Even Ron is fine.

"When the Dementor looked at you, you suddenly became strange."

"I thought you were cursed." Ron recalled the scene just now. He looked a little scared. "You seemed to become stiff, fell off the seat, and started to twitch..."

Then he and Hermione told the whole story in detail, including how Harry fainted and how Professor Lupin drove away the Dementors in the end.

"It was a silver light," said Hermione. "I didn't see what it was, but the Dementors looked scared."

"Silver light?" George whispered. "That must be the Patronus Charm."

"I didn't expect he could do this." Fred seemed a little surprised. "It seems that our Defense Against the Dark Arts professor this year has some skills."

"Don't be happy too soon." Cedric said beside him: "He may also be the professor of Care of Magical Creatures... Remember? Professor Kettleburn will retire this year."

"Damn it, how could I have forgotten this." Fred scratched his head. "We are not going to have another semester of reading class, are we? I've had enough of it."

Cedric shrugged, even though he was the same, the Defense Against the Dark Arts professor at Hogwarts was always so disappointing.

With the experience of the past two years, he wouldn't be surprised if another useless professor came this year...

"Patronus Charm?" Hermione suddenly realized the point.

"Yes." Fred explained: "Kyle just used this spell to resist the Dementors. Look, our condition is much better now."

When he said this, Hermione realized that it was indeed the case.

Ron, Neville... and those who were peeking outside, all looked somewhat pale, and she was probably about the same.

But the expressions of Kyle and the others were normal, and they looked no different from usual, even the youngest Ginny was the same.

"Patronus Charm?" Hermione muttered softly and memorized the spell in her mind.

At this time, Lupin also came back. He looked at everyone and said with a smile: "I just asked the driver, we will arrive at Hogwarts in another thirty minutes."

This was really great news for Harry and he couldn't wait to get back to the warmth and comfort of the castle.

Most importantly, the professors and Dumbledore are there... the Dementors would definitely not dare to go in.

But Harry still couldn't understand why he was the only one who fainted while everyone else was fine.

He asked Professor Lupin, but he just shook his head and comforted him.

"Dementors force us to remember our worst past events. Our pain becomes their power. Perhaps it is because your experiences are different from others that it arouses its interest."

He pretended to be relaxed and said, “And you don’t have to worry too much, because I found that the Dementors’ behavior here is completely different from that in other boxes.

It could not control its desire to eat, and actively absorbed the emotions around it... This ability, which is unique to Dementors, cannot be resisted even by adult wizards.

You are only thirteen years old, it is normal for you to faint."

Harry still felt that his statement was a bit far-fetched.

"But Ron and Hermione didn't faint," he whispered, "and Neville didn't either."

Seeing Harry's depressed look, Ron wanted to comfort him, but he didn't know what to say.

Just as he was trying to think, he suddenly turned his head and saw something flash on Hermione's clothes.

Ron's eyes lit up and he quickly said, "Is it possible that we are wearing the badge?"

He pointed to a similar badge under his collar and said, "Remember, this is what Kyle gave us before, and it's made of dragon scales.

Even Dementors would be afraid of a creature as powerful as a dragon."

"How is that possible?" said Hermione. "Even if Dementors are afraid of dragons, they won't be afraid of a scale."

"It may also be possible... um... it has a certain restraining effect."

To be honest, even Ron himself felt that this reason was a bit far-fetched, but the problem was that he couldn't think of a better one right now, so he could only bite the bullet and continue: "We were wearing our badges, so nothing happened. Only Harry fainted because he changed into robes first."

"What about Neville? He doesn't have a badge either." Hermione frowned.

In the corner, Neville heard his name and raised his head tremblingly.

His current condition was even worse than Harry's. Even though he had eaten a large piece of chocolate, his whole body was still shaking uncontrollably.

Somehow, after combining what Professor Lupin and Ron said, Harry immediately felt much better.

Although it was a bit self-deceptive to think so, compared to being weak and timid, he would rather believe that it was the Fire Dragon Badge that worked.

"What Fire Dragon Badge..."

Neville stood up and looked at Kyle hopefully, "Any more? I can buy some."

He really didn't want to experience the coldness that seemed to penetrate deep into his soul again.

"Yes... yes..."

Kyle pulled out a bunch of colorful badges from his pocket. "But these things shouldn't be useful against Dementors..."

“I bought it!”

Before he could finish his words, Neville took all the badges from his hand.

"How much."

"Hmm... two Galleons each."

Neville's hand paused as he took out the money. "How much?"

"Two Galleons." Kyle explained, "This is a genuine dragon scale, which is valuable in itself. The pattern on it is also hand-carved by local Romanian people. Two Galleons is not profitable at all."

Neville looked at the six badges in his hand and hesitated.

Twelve Galleons in total... He didn't have that much money.

Mrs. Longbottom usually didn't give him much pocket money because he was always losing things.

"Why don't you just forget it? It's actually useless." Kyle persuaded again.

He has plenty of ways to sell things, there's no need to use this method.

The Dementors will be stationed in the castle permanently this year, and it will soon be apparent whether they are useful or not.

False advertising will lead to product returns in the future and will also cause serious negative impacts. The reputation they have accumulated over the past three years may collapse in an instant.

It's not a good deal no matter how you look at it.

But just as Neville hesitated, Lupin spoke unexpectedly.

"Perhaps, it can really play a role."

These words seemed to make Neville determined.

He gave Kyle three more badges and took out six Galleons from the pocket of his robe and handed them to him, "That's all I have. Buy three!"

"this……"

Kyle looked at Lupin, not understanding what he had just said.

Facing Kyle's questioning gaze, Lupin shook his head, walked up to him while no one was paying attention, and explained in a low voice: "When facing Dementors, the most important thing is courage. Only if you are not afraid of them can you not be affected.

If Mr. Longbottom was convinced that the badge had the effect of warding off Dementors, then it would work.

I think, as the youngest recipient of the Order of Merlin, you should understand what I mean."

If I firmly believe it will work, will it work? Kyle thought seriously.

This is not difficult to understand, as many magic spells are like this. When he was learning the Patronus Charm, Newt repeatedly reminded him that in order to successfully release a complete Patronus, one must have a strong enough belief.

The same goes for the Apparition technique he was learning. Once he began to doubt himself, he would fail.

"You mean..." Kyle asked thoughtfully, "The badge can give him the belief that he is no longer afraid of Dementors?"

"You could say that."

Lupin nodded. "But the prerequisite is that the Dementors must be able to control their desire to eat."

He pointed in Neville's direction again and said softly, "But at least it seems to be okay now."

Kyle looked up as well.

Ever since he got the badge, Neville stopped shaking, his pale face became much rosier, and he looked much better than before.

“The badge is just a carrier. It can also be a stone, a leaf, or a dead branch… What’s important is that people believe from the bottom of their hearts that it is useful!”

Lupin looked at Kyle, and suddenly changed the subject, with a strange expression, "But, isn't it a bit too expensive to sell it for two Galleons?"

"No, sir." Kyle smiled and said, "You can go to Diagon Alley to ask about the price of dragon scales. In the potion shop, the price is clearly marked at one Galleon and fifteen Sickles per piece, and there is no discount.

Add to that the cost of drawing the pattern and the door keys to and from Romania, and two Galleons is already the cost price. I'm not making any profit at all."

Lupin was speechless for a moment.

Indeed, anything related to fire dragons would be priced quite high. He sighed and returned to his seat.

At this moment, there was a sudden commotion outside, and as soon as Lupin left, someone walked into the box.

"Sorry, I just overheard your conversation... Do you still have the same badge as before?"
