"What is the Patronus Charm?" Harry asked.

"The Patronus Charm is magic against Dementors." It was Brace who replied, "The spell is Expecto-Patronum!" ”

"Is it true that the lower grades can't do it?" Harry looked at Catherine and Draco.

“Expecto-Patronum！” Draco flicked his wand and a silver snake emerged from the tip of his wand and hovered over his head.

"Divine Guard!" Catherine's wand only spewed out a silver mist at first, but they separated and converged into a large bird.

"Fawkes?" Lupin looked at Catherine in surprise.

"It's not a phoenix." Catherine didn't explain, and the others didn't pay much attention, but drew their wands and recited the Patronus Charm, only it was all a silver mist at first.

"Think of something happy and have a firm belief in protecting it!" The crowd began to close their eyes and remember as they were instructed.

Soon, a stag popped out of the silver mist and began to circle Harry, and Hermione soon conjured a cat, followed by Pansy's leopard and Brace's crane, and it took a lot of effort for Ron to conjure a dog.

Lupin stared dumbfounded at the silver animals running around in the box, and it was hard for him to believe that the current third-year students had such a high level of strength.

"Remus, what about yours?" Harry asked suddenly.

Lupin hesitated, waved his wand and recited the incantation, and a wolf flew out, thicker and more condensed than the other animals, and looked unusually calm and vigorous.

"Why is there such a big difference?" Hermione asked, puzzled.

"Your Patronus is just a façade, and you won't be able to sustain the Dementors for long, let alone drive them away, let alone destroy them."

"Really?" Draco raised an eyebrow in questioning.

As soon as the words fell, the train suddenly shook and stopped, and there was a thudding sound in the distance, and then all the lights suddenly went out. Thankfully, the silver light from the Patronus illuminated the room.

"What's going on?" "Arrived?" Harry and Ron asked.

"There is no broadcast." "It's not the scenery around Hogwarts outside." Brace and Pansy immediately retorted.

"Something isn't right." Draco waved his wand, causing the table that stood in his way to disappear.

"Let's ask the driver!" Hermione got up and said.

"Nope! Stay where you are and keep quiet! Catherine closed her eyes suddenly, "I hear a lot of cloak sliding outside, and one of them is coming this way, here!" ”

A cold air poured in from under the door, and everyone clenched their wands.

The door slowly opened, and a shimmering, gray, emaciated, crusted, corpse-like hand reached through the crack in the door.

"Dementors!" Lupin jerked to his feet. With a hard swing of his wand at the doorway, his Patronus immediately rushed over and slammed a cloaked monster with a ceiling above its head into the air.

Lupin rushed out of the doorway, followed by most of the young wizards, except for Hermione, who was held back by Catherine.

"Tell the professor to come quickly!" After Catherine finished speaking, she threw Hermione out of the compartment with her magic and locked the door. Then he took two steps back and sat down next to the window.

"A cold and dark environment, a warm silver light." The memories in Catherine's mind were rapidly receding until a long-lost memory resurfaced in front of her.

Dumbledore and Snape, who had just learned from Guò's address book that the train had encountered Dementors, left Hogwarts. received a distress message from Hermione, saying that Catherine had an accident, and the two hurried to the scene.

Dumbledore immediately conjured his Patronus to help Lupin chase away the Dementors. Snape, on the other hand, blew open the door of the box and broke in.

At this time, Catherine was with her eyes closed, and her expression was very painful. Her body was trembling violently, as if she was enduring something, her patronus had shrunk strictly, only the size of a sparrow, but still hovering around her to ward off the chill for her, and the phantom Tracey stopped on the red-haired girl's shoulder, and when she saw Snape come in, she was tired and turned back to her original form.

As soon as Snape approached, Catherine grabbed his hand and shouted, "No! Don’t-leave! Don’t-leave-me-along!” (Nope!) Don't leave! Don't leave me alone! ）

Before the words fell, a strong wave of magic power poured out of Catherine's body, Snape's face changed, and he hurriedly cast the most powerful armor spell on himself, and then felt a huge force hit him hard, and then there was a loud explosion.

Half of the carriages were blown up, most of the luggage in the luggage racks was destroyed, and a small part was swept away by the strong winds.

Catherine, though unharmed, collapsed and slammed into the railroad tracks on the ground, but fortunately Snape kept pulling her, Harry and Draco arrived in time to help, and the train was forced to stop by the Dementors before it happened.

"What's going on?" With such a big movement, Dumbledore and Lupin couldn't care less about the Dementors.

"It's supposed to be a Magical Riot!" Snape breathlessly said, "I need a portkey." ”

Dumbledore picked up a broken door panel on the ground, pointed his wand at it and said, "Mentos!" He then threw the door panel to Snape.

As soon as Snape reached out to take it, he and Catherine in his arms disappeared.

"Quiet!" Dumbledore cast a loud incantation, "All students stay in their cubicles, and the two student council presidents and prefects work together to maintain order. With a powerful wave of his wand, a silver light enveloped the entire train in an instant.

"Remus! It's up to you to handle the car. I'm going to negotiate with the Dementors. With that, Dumbledore floated straight into the air from the bombed-out compartment.

"My mom is going to kill me!" Ron's whole body swayed, he was unfortunately affected by the magic of Catherine's riot just now, although the person was fine, but the historic wand was directly broken in two, "My wand is finished, and the luggage is gone." ”

"Professor Lupin, can you use the Flying Charm to help us get it back?" Hermione's luggage was nowhere to be seen.

"Yes, but not much." Lupin waved his wand repeatedly, but all he recovered was Harry's luggage, some of Ron and Hermione's clothes, and as for his own, not even a piece of cloth was missing, but luckily wizards have always been used to carrying valuables with them, otherwise Lupin would have gone bankrupt.

"Looks like I'm going to have to buy new clothes." Lupin said helplessly.

"Professor Lupin, you're six feet three inches tall and weigh ......," Brace suddenly snapped a string of counts, "am I right?" ”

"No—that's right!" Lupin was stunned for a while before nodding, he really didn't expect that he had only been in contact with the other party for less than an hour, and his height and weight would be clearly felt, could it be that Slytherin is so peculiar now?

"Don't be surprised!" Pansy explained angrily, "Brace's goal is to see through the real three of women at a glance. ”

"Professor Lupin, don't worry!" Draco also reassured, "When Catherine wakes up, she'll immediately compensate you for all your losses." ”

"But what about Ron's wand?" Harry didn't think Draco was wrong at all, as Catherine could afford to lose it completely, "Would the Headmaster agree to him taking time off work to buy a new one?" ”

"I'll explain to Dumbledore later, and he'll agree."

But as soon as Dumbledore learned all about the situation, the Headmaster decided to take Ron to buy a wand, so by the time the others arrived at Hogwarts by train, Ron was already standing at the gate of the castle happily waiting for them with a brand new wand box.

"Fourteen inches long, wicker, with a unicorn's tail hair, it's best suited for spells, and the headmaster agrees." Ron opened the box and showed off.

"How much?" Draco asked abruptly.

"Eleven Galleons." Ron suddenly became embarrassed, "The headmaster asked Mr. Ollivander to send the bill directly to Catherine. He closed the box and looked at Harry embarrassedly.

"Don't worry! She can afford it! Harry patted his friend on the shoulder, then remembered to ask Catherine about her, "By the way, where is she now?" ”

"Medical Wing! Madam Pomfrey said that Catherine needed a week's rest and that no one was allowed to visit her, so I came here to wait for you. Ron looked worried.

When Harry and Draco heard this, they immediately ran towards the medical wing, and the others hurried to follow, but in the end, they were shut up and had to turn back to the auditorium.

By this time, the Sorting Ceremony was over, and Dumbledore was standing up to explain the do's and don'ts for the year, especially with regard to Dementors.

The six young wizards hurriedly crept back to their positions, and when they sat down, Dumbledore had already begun to introduce Lupin, and they quickly applauded vigorously, which immediately attracted sideways glances from all around, especially Snape.

He glared at Draco fiercely, and the three Slytherins hurriedly lowered their hands; But when he swept towards Harry, the Golden Triangle grew even stronger; Finally he turned to Lupin, his face full of naked hatred.

When everyone discovered Snape's anomaly and began whispering about it, Dumbledore began to introduce the new professor of the Conservation of Magical Creatures class, Rubeus. Hagrid.

The Golden Triangle stared at each other for a moment before joining in the Gryffindor's extraordinarily enthusiastic applause.

Draco, Pansy, and Brace looked at each other, and they knew the inside story well, and Yan Zòng suspected that Dumbledore was trying to compensate for hiding from Hagrid last year, although it seemed quite reasonable, but the thought that they might encounter monsters such as the eight-eyed spider in their future lessons made the three Slytherins shudder.

The three of them immediately gathered together and discussed softly, Theodore and Daphne next to them soon joined in, and even Millicent pricked up his ears and leaned over, until Dumbledore announced that the party was over, and the six heads were separated. (To be continued......)
