The dim lights seemed to dispel the cold. At least when the surroundings were lit up, voices began to be heard on the train.

"What was that just now..." Kanna asked.

"Dementors." Kyle put the luggage on the shelf and said, "Guards of Azkaban."

"I know it's a Dementor." Connor shook her head. "I'm asking what the spell you used just now was to dispel the cold."

"Oh, you mean that..." Kyle took some more chocolate and distributed it to everyone, "The Patronus Charm is also the simplest and most effective way to resist Dementors.

If a perfect Patronus is summoned, it can even damage Dementors."

"Ah? Didn't you use the illumination spell just now?" Fred next to her asked subconsciously after hearing her words.

He only remembered that after Kyle took out his wand, the box lit up. Isn't this an illumination spell?

Kyle ignored him.

Although both the Illumination Charm and the Patronus Charm involve light, they are very different... Well, if you don't look closely, they are really similar.

"A perfect patronus?" Kanna was curious. "What does it look like?"

“The light will condense into a silver-white animal,” Kyle said, “which can run and jump freely in the air, just like it’s alive.”

"Is this difficult?" Connor asked.

She remembered that she had not seen any animals in the carriage just now.

Although she really wanted to learn this spell, there was no point in wasting her time if even Kyle couldn't do it.

"It's hard to say. It's difficult, but not that hard either." Kyle explained, "If you have a deep enough happy memory, it will be easy to learn this spell."

He learned the Patronus Charm from Newt in Romania, and the memory he chose was mainly the excitement of receiving the acceptance letter to Hogwarts.

And the way Snape looked like he was going to dig his toes through the castle floor after hearing the words "Half-Blood Prince".

The effect is amazing.

He finished learning the Patronus Charm in just two days.

But there was no need to use the complete Patronus Charm just now. The Dementors came to inspect the train under the orders of the Ministry of Magic. The focus is on the Ministry of Magic, not the Dementors.

So it is impossible for them to leave before completing this order, and the Dementor just now proved this.

Forcible expulsion may backfire or even anger them.

There are hundreds of students here, and Kyle can't guarantee that he can protect everyone, even with Professor Lupin included.

In situations of extreme fear, not everyone will obey.

…

After the Dementors left, the train started running again.

Several people sat in their seats, discussing what had just happened.

George was unlucky. His teeth were chattering, making a series of "clicking" sounds. Naturally, he was laughed at by everyone. He tried his best to explain that it was because of the cold, but no one believed him.

It doesn't matter whether they were scared or frozen. Now everyone needs a new entertainment to dispel the negative impact of the Dementors. George is the best candidate. There is no other way. He just caught up with it.

Among them, Fred laughed the loudest.

As for George himself...anger and shame are sometimes more effective than happiness. While trying to defend himself, he had long forgotten about the Dementors.

The train continued to move north, and outside the window was a continuous curtain of rain.

"Should we go check on Harry?" Fred, who had just finished teasing George and was now refreshed, suddenly said, "I seemed to hear Ron shouting just now, saying that he fainted."

"Okay, let's go and take a look." Kyle nodded.

He casually picked up two boxes of chocolates from the table and left the box.

The box where Harry was was easy to find. It was at the very back, surrounded by a bunch of people.

Obviously, they were not the only ones who heard the scream just now.

Kyle and his friends didn't have any concerns, and didn't care whether it was a professor or not. Fred and George squeezed through the crowd and walked in under the pretext of visiting their brother Ron.

Harry fainted on the floor, groaning continuously, as if he had dreamed of something terrible.

Hermione and Ron kept calling him.

The professor is writing a letter.

When Kyle and others walked into the box, he looked up, and after his eyes stayed on Fred and George's red hair for a while, he lowered his head again and did not drive them away.

"Kyle..." Hermione asked anxiously, "Is there any way you can wake Harry up quickly?"

"That's not difficult."

Kyle thought for a moment and said, "If you want to be gentle, just wait for him to wake up. If you want to be rough, just pour cold water on his face. It's best to pour cold water with ice chips. You don't need to use too much. One basin will be enough."

"But where can we find ice water..."

"You're a wizard, Ron," Hermione said unhappily, pulling out her wand.

"No need." Kyle waved his hand, "I have a better idea."

By this time, Professor Lupin had finished writing the letter, and Kyle walked over and opened the window.

A cold wind mixed with rain blew in and blew right on Harry's face.

Harry, lying on the ground, shuddered violently and opened his eyes dazedly.

"Look." Kyle closed the window again.

Ron and Hermione hurriedly helped Harry back to his seat.

"Are you okay?" Ron asked nervously.

"Nothing," Harry said, and looked quickly toward the door. The guy in the cloak was gone, and there was only a row of heads outside the door, which quickly shrank back after meeting his gaze.

"Where did that thing go? Who was screaming just now?"

"Nobody screamed," said Ron.

"But I heard... a woman screaming."

"Maybe the Dementors brought back some bad memories for you."

Kyle took out the chocolate and handed it to him, "Eat some, it's good for you."

Behind them, Professor Lupin was also holding a large bar of chocolate.

However, he looked at the high-end chocolate in Kyle's hand, which was beautifully packaged and had a string of French words written on it, and then looked at the large chocolate in his own hand, which was simply packaged and contained three pieces, and silently put it back into his pocket.

"That chocolate bar must be five Sickles a piece." Lupin muttered to himself, "Why are all the young wizards nowadays so rich?"

On the other side, Harry took the chocolate, took a small bite, and was surprised to find that a warm current suddenly surged through his body, and he felt much more comfortable all of a sudden.

"Thank you!" He looked at Kyle, "This chocolate is really good. Where did you buy it?"

"I don't know either." Kyle spread his hands. "This is a birthday present from a French friend of mine. It's a big bag of candy, and this is one of them."

"French goods... must be very expensive." Ron swallowed.

"Ten Galleons a piece." At this time, Cedric suddenly said, "When I was traveling in France before, I saw this brand of chocolate in a magic shop. It is said that fifty-year-old golden bee honey and milk from Riem cows are added to it. It is ridiculously expensive."

"Dang..."

Behind him, Lupin dropped his wand to the ground and looked at Kyle in shock.

"Ten Galleons...a piece of chocolate?"

"Kids nowadays are so damn rich!"
