I was expelled from Hogwarts?

The Patronus Charm is indeed the best magic against dementors.

Because it can concretize positive emotions such as hope and happiness into a physical animal, which can cause damage to dementors.

Under the guidance of Sirius, the whole class recited the incantation of the Patronus Charm.

"Call God to protect you!"

"Remember, just like Boggarts, dealing with Dementors requires a heartfelt smile." Sirius paced the classroom, he said loudly:

"So, when casting the Patronus Charm, you should do your best to recall the happiest memory in your heart."

Rove squinted his eyes and slowly recalled that he had been in the magic world for many years, and many of his memories had long been blurred, but there was one scene that he still remembered clearly...

That is knowing that I can go to Hogwarts to learn magic!

"Call God to protect you!"

Rove yelled along with the crowd, and the tip of his wand spewed out a puff of gas. Although it was not formed, it shone with silver light.

"Very good!" Sirius looked at the little wizards and praised:

"There are already many students who have white mist in their wands. Next, I will release the dementors. You can feel the difference again."

Sirius opened the case, and a dementor slowly floated out, its hooded face turned toward the student, its cloak clutched in glowing, scabbed, rotting hands.

Although the fire was blazing in the fireplace, the temperature in the entire room dropped rapidly, and everyone could feel a chill sweeping from the dementors, like the icy breath from deep underground.

The dementor floated towards the window, as if trying to escape the room, but the door and window were completely sealed, and it couldn't get out at all.

Sirius folded his arms and asked with a smile, "Which one of you will come first?"

McMillan walked towards the dementor excitedly, his wand belching smoke just the first time, which made him burst with confidence.

But as he approached the dementor, the chill seeped through the air into McMillan's bones, and before long every muscle was tensing, from jaw to toe.

McMillan was panting and struggling to breathe. He tried to yell out the spell, but his tongue didn't work at all.

The dementor had no reason not to eat the small snacks delivered to the door. It went straight to McMillan, but was slammed away by a big silver dog.

Sirius put away his wand, he took out chocolates from his pocket and handed them to McMillan, then looked at the students, said with a smile:

"It's one thing to practice the Patronus Charm by yourself, and quite another to practice it next to dark creatures like dementors.

I used to have a friend who was the quickest wizard among us to use a full Patronus, but when it came to dementors, he couldn't summon them every time.

To summon the Patronus, happy memories are of course essential, but it also depends on this..."

Sirius pointed to his heart and said, "The courage to face fear!"

He looked at the students and asked loudly again: "Who else dares to try?"

"Professor Black..."

Sirius turned his head in surprise and saw the always timid Neville walking out of the crowd. He wiped his sweaty palms on his clothes and whispered:

"I...I want to try."

"Of course, Neville." Sirius laughed, "You're very brave, come on, kid!"

Neville swallowed his saliva, and when he was trotting forward, his left foot caught his right foot and almost fell to the ground.

The students couldn't help laughing.

Neville, whose face was flushed, walked not far from the dementor. He was trembling uncomfortably, and his whole body was tightly wrapped in a thick robe.

Sirius whispered, "Breathe, Neville, breathe out the fear, drive away the shadows... breathe out the protection!"

The tall figure of the dementor enveloped Neville, and for a moment everyone could only hear his heavy breathing.

But Neville didn't back away this time. He raised his wand and kept shouting, "Guardian...Guardian...Guardian...Guardian!"

Sirius' big silver dog reappeared, hitting the dementor's belly with its head, causing it to lose its balance and slump down hard on the ground.

Neville's skin was damp and sweaty, cold and clammy, and every breath was accompanied by a slight gasp.

Neville, like McMillan, failed to blow out the white mist, but when facing the dementor, he yelled the spell firmly, and hadn't stepped back yet...

The Hufflepuffs applauded Neville, and Hannah screamed from the crowd, "Neville, well done!"

Neville was a little embarrassed, a simple and honest smile appeared on his face, and quickly trotted back into the crowd.

"Who else wants to try?" Sirius asked loudly again, his gaze scanned the crowd several times, and many students lowered their heads.

Rove was about to step forward, but Shirley beside him had already taken a step forward.

Everyone focused their attention on the beautiful girl with the slender ponytail. She was slim and graceful, with a cold demeanor. Even if she just stood quietly, she was extremely attractive.

Shirley raised her wand and said softly, "Call God to protect you!"

She succeeded, and the wand spewed out a puff of silvery gas, but as the dementor approached, the wand was like a lamp with a low battery. It only flickered a few times, and the silver mist disappeared.

Shirley felt a chill piercing her whole body, she pursed her lips tightly, and glanced at Rove not far away from the corner of her eyes.

Rove stepped forward, walked out of the crowd, ready to rescue her at any time, as if sensing his gaze, the boy grinned at her.

Shirley, who was still uneasy at first, suddenly felt at peace. She had never told him, but as long as she could see his figure within sight, she felt at ease.

Happy memories emerged bit by bit, like a clear spring flowing into the heart, the ponytail girl's eyes became firm, she raised her wand with both hands, and shouted:

"Body guard!"

A fuzzy silver shadow appeared, like a barrier, blocking the approach of the dementor. Although it could not drive away the opponent, it sent a little warmth towards her.

"It's really excellent!" Sirius applauded and said with satisfaction: "Very few people can create a fuzzy Patronus when facing a dementor for the first time.

Ravenclaw plus ten points! "

Shirley turned around and returned to the crowd. Rove gave a thumbs up and said with a smile, "Amazing!"

Xue Li patted her chest lightly and took a big breath. She smiled at Rove and said sweetly, "Actually, I just took a chance."

Rove was full of doubts, but Shirley didn't explain, she just turned her head, the corners of her mouth curled up, looking very happy.

Soon, Rove walked towards the dementor with his wand in his hand.

He was about to raise his wand when the dementor seemed to smell something frightening, and it backed away and burrowed back into the box.

"..."

Everyone is a little speechless, what did you do to it?

Rove also had an innocent face, with a conscience of heaven and earth. He just let the dementor live with the Thunderbird and gave it a lot of electric shock therapy every day...

Other than that, really nothing has been done!

Believe me!

Rove never abused "little animals"! !
