Chapter 156 Goodbye, Dementors

"It's all your fault, bad Scabbers." Ron tapped Scabbers' head gently.

"Oh, because your cute mouse ran away, there are people sitting everywhere now." Hermione complained.

"This, this is still empty." Harry found an empty seat and called to his companions.

The four of them sat down in the compartment, with Harry sitting on one side and the man sprawled on the seat.

Hermione, Ron, and Aiden sat together, with the two of them sandwiching Ron in the middle.

"Is this guy dead?" Ron looked at the sickly man slumped in his seat.

"Ron, be respectful, this is our professor, Remus John Lupin," Hermione explained.

"How does she know everything? And isn't it a bit crowded here?" Ron complained casually.

"Maybe there's some in the trunk, and we really need some space."

Aiden pulled out his black walnut wand and tapped it on the wall.

The space inside the box expanded steadily, and even the sleeping man beside him was not affected.

"Cool." Ron praised, "And Harry, you did a great job too."

"I really didn't inflate her on purpose, I just couldn't control it," Harry defended.

"Ron, this is no joke. Harry almost got expelled." Hermione scolded.

"It doesn't matter. Their memories have been erased anyway. I did it myself. This is a technique that even Dumbledore praised." Aiden winked at the three of them.

"Is he asleep?" said Harry, pointing at Lupin.

"Probably." Ron responded.

"I have something to tell you." Harry stood up and closed the partition door.

Aiden knocked on the wall casually, and a silent spell covered the entire carriage.

Harry told his two friends about Sirius, and also told them all the information Aiden had told him.

"You mean, Sirius Black escaped from Azkaban for you?" Ron raised his voice in surprise.

"But he'll be caught, I mean everyone's looking for him," said Hermione.

"Of course, but no one has ever escaped from Azkaban before, and he's a lunatic." Ron said teasingly.

"Thanks, Ron," Harry teased.

"Okay, let's not talk about these heavy things. Let me share with you some memories of Aunt Harry." Aiden brought up a new topic.

"Harry's aunt, isn't she inflated? What else is going on?" Hermione asked in confusion.

"Huh, you don't know, Harry, your aunt likes to buy expensive gifts for Dudley and then observe your reaction.

Moreover, although she likes to keep dogs, she will throw sick dogs into the river to drown them. I know how to deal with her next time I see her. "

Aiden gave Harry a wink, and Harry understood.

"Well, it seems I can give her a good beating next time I meet her, thanks..."

Just as Harry was about to speak, the train creaked and there was a sound of wheels rubbing against the rails.

"Why did the car stop? We haven't reached the station yet." Hermione looked out the window in confusion.

"Aiden, Aiden, what's wrong with you?" Ron looked at Aiden in horror.

At this moment, Aiden took off his hat, and anger and disgust were intertwined in his heterochromatic eyes.

'System, this is...' Aiden's voice echoed in his mind.

"Yes, this is the product of a dead soul being forcibly retained in the world," the system replied.

"No wonder they are called dark creatures. I can't imagine what kind of torture could make a creature degenerate into this state." Aiden was furious.

Outside the door, Ginny and Neville came to Harry's private room because the train was suspended.

The train shook violently, and Ginny fell into Harry's arms, while Neville sat on Crookshanks.

"What happened? Did something get into the car?" Ron looked at the frozen car window in horror.

"Yeah, a dead soul, what a disgusting smell." Aiden made a vomiting expression.

Along with the cold air and suffocating despair, a tall, human-like shadow wrapped in a tattered black robe floated in.

Harry felt his emotions draining away, and at the same time he heard a woman's scream, and fainted like Ginny.

"Get out. There is nothing here that you are looking for. If you don't get out, I will make you completely disappear."

Aiden spoke a language that no one could understand.

"Heh heh heh heh~"

The Soul Eater ignored Aiden's threats. Days of hunger had made it lose its mind. It squeezed into the carriage and wanted to devour the happiness of the wizards present.

Expecto Patronum

Endless swarms of butterflies erupted from the carriage, and the Dementors faced the impact of the Patronus.

A group of butterflies gathered in the air, and a giant silver-white dragon appeared outside the carriage. The dragon opened its mouth and directly swallowed the Dementor.

The Dementors continued to dissolve in the dragon's belly, letting out sharp roars.

The powerful magic of the Patronus also dispersed all the Dementors that got on the bus, and the Dementors outside who heard the miserable screams of their companions also fled in all directions.

Lupin was too embarrassed to continue pretending to sleep with such a huge noise, so he stood up, looked out the window at the dragon chasing the Dementors, and didn't know how to start talking for a moment.

Aiden saw his embarrassment and gave him a hug.

"Long time no see, Uncle Lupin." A bright smile bloomed on Aiden's face.

"Oh, wait, who are you?" Lupin's memory brought him back to that night thirteen years ago.

"Which Prewett child are you? Have you grown up so much?" Lupin finally recognized Aiden and was filled with emotion.

"No, how come you still remember me? Weren't you only one year old at that time?" Lupin asked.

"Maybe I'm gifted." Aiden pretended to be mysterious.

"Oh, this is really...Okay kid, I have to go to the front of the car to check the situation. Please help me take care of these little wizards around."

Lupin said, pulling out a bar of chocolates and handing it to Aiden.

"Feed Harry a little once he wakes up. It will make him feel better."

Having said that, Lupin set off for the front of the train.

......

"Harry, Harry, are you okay?" In the darkness, Harry seemed to hear Hermione calling him.

Harry opened his eyes and sat up, his friends gathered around him.

"Eat it, you'll feel better." Aiden handed the chocolate to Harry.

"What was that just now?" Harry put the chocolate into his mouth.

"Dementors, guards of Azkaban, disgusting, filthy, sickening dead minds," Aiden said.

It was the first time Harry had detected such a strong hostility in this friend who never easily showed his emotions.

"You were so stiff just now that we thought you were having a seizure," said Ron.

"Well, how are you? Did you faint? I seemed to hear someone screaming just now." Harry covered his head.

Ron and Hermione looked at each other, and Hermione said carefully, "Harry, no one is screaming."

"We didn't faint, but it was really strange just now. I felt like all the happiness in my body was drained away. Fortunately, Aiden used the Patronus Charm." Ron said with lingering fear.

"What spell?" Harry asked.

"The most ancient and powerful white magic, the weapon that ancient wizards used to protect themselves in crazy times." Aiden's eyes were very deep.

"Can you teach me?" Harry asked again.

"There will be a chance."

Aiden said nothing and walked outside the carriage to inspect it.

Only three people who were awake were left in the carriage to look after the two unconscious people.
