The voice rolled up a layer of silver-white air waves, which quickly swept across the entire stadium, and the young wizards affected by the Dementors were suddenly freed from their cold and desperate mood.

Professor McGonagall held her wand and scanned the surroundings, and quickly made a judgment. She said to Felix and Dumbledore: "I'll go to the stage."

At this moment, Harry landed smoothly. Madam Hooch hurried forward to check, and the Gryffindor players rushed up. At the same time, Cedric looked back blankly at the sudden situation on the field - he was still holding a golden snitch in his hand.

The young wizards who had just gotten rid of the influence saw this scene, especially the Hufflepuff young wizards who almost overturned the entire stadium, and the huge cheers surged like waves.

The Dementors that were originally lingering were ready to move. The little guy with a huge threat could not let them give up the feast that was within their reach. Some Dementors flew into the air, and some Dementors lifted the tattered turbans on their heads and kept absorbing the happy breath in the air...

Dementors have no eyes, and they perceive everything outside by smell and emotions, but today, they had a new experience - they saw the light.

The Swift Patronus rushed into the group of Dementors in the blink of an eye, and its whole body was shining, brilliant and dazzling. The silver-white air wave exploded, surging and raising waves of silver waves.

The Dementors were almost instantly disintegrated. They kept retreating, but the silver Swift Patronus was as fast as lightning. Its flight trajectory wove into a fine net in the air, encircling all the Dementors. Any Dementors that touched the fine net would fall back.

They were completely trapped.

Under the dull eyes of the little wizards, the gaps in the net became smaller and smaller, gradually turning into a hemispherical cover. The Dementor's figure was gradually covered up, and finally, the Swift's form disappeared, and a half-moon appeared in the center of the field.

The light of the "half-moon" pierced the foggy court.

A little wizard said absentmindedly: "Professor Hepp conjured a moon?" His companions completely agreed with him.

Many students looked up at the sky, as if to confirm whether the moon was still there, but all they could see was a black sky covered with dark clouds.

Felix's eyes were filled with silver-white light. He was in a strange mood now. The Patronus was constructed of pure, happy, and positive emotions, but because it had no human emotions and would not despair, the Dementors could not harm them.

The most important thing was that Felix found that the light stimulated by the Patronus seemed to have a huge inhibitory effect on the Dementors.

He borrowed the perspective of the Swift Patronus and found that the Dementors in the encirclement seemed to have shrunk very slightly in size...

"It might be an illusion..." Felix muttered softly, and the light of the "half-moon" became stronger, and it really looked like a silver moon rising.

The expression on Dumbledore's face became strange. He was indeed very angry. He was angry that the Dementors dared to break into the school. He had planned to teach them a lesson.

But now it seemed that if he had not dissuaded them in time, Felix might do something amazing.

The Patronus was recognized as a defensive magic that could only drive away but not kill Dementors.

But Dumbledore would not think so superficially. The simplest logic was - if the Patronus could not harm the Dementors, what reason did they have to be so afraid of this magic?

He whispered: "Felix, you can teach them a lesson, but the Dementors cannot be killed. They are employees of the Ministry of Magic."

Felix shrugged, and a stream of light flew out from the full moon, turning into a silver swift again and stopping in mid-air.

The "half moon" gradually faded away. The young wizards stared at it with wide eyes. They chattered and discussed -

"Do you think the Dementors have become smaller?"

"It seems to be true..."

"Could it be a problem of perspective? We are standing on a high place."

"Impossible, when I went to Hogsmeade, I secretly glanced at the Dementors guarding the door. Each of them was at least six feet tall. Now I can see that they are less than five feet..."

"..."

After the Dementors saw the light of day again, they barely had time to take a look at the motionless Patronus in the air. They desperately fled from this place, and the black tattered cloth strips at their hems were almost bent at an angle parallel to the ground.

The body of the silver swift suddenly expanded, magnified thousands of times, with a wingspan of nearly twenty feet. It was far behind the Dementors, and from time to time it burst into a strong light.

The young wizards burst into huge cheers. In their opinion, this was Professor Hepp venting their anger.

The Dementors fled even faster.

After a while, the exaggerated Swift Patronus flew back and stood far away at the edge of the Quidditch field, welcoming the admiring gazes of the young wizards.

"It's so handsome!"

"It's over." Felix sighed, but he didn't mean to take back the silver Patronus.

Dumbledore looked at him with magical eyes.

"Felix, I need to remind you that although Dementors are not outstanding in intelligence, they have a vague group consciousness - I told you that they can find out if one is missing."

Felix hesitated and said, "Can't I leave it for a day?"

Dumbledore seemed to be amused, "Oh, unless you want to be found by the Ministry of Magic. Thousands of people have seen your Patronus, you can't make excuses."

"What if it was done by 'Sirius Black'? He learned powerful dark magic from Voldemort..." Felix said tentatively.

"In that case..." Dumbledore smiled, "It's not a big problem, but you have to produce strong evidence to deal with the Ministry of Magic's interrogators. It's most likely Fudge himself."

Felix smacked his lips, "Strong evidence, okay."

He waved his hand, and the huge silver swift standing at the edge of the field chirped crisply, and spit out two black shadows from its beak - they were barely three feet tall deformed Dementors.

They left almost in a hurry, and Felix and Dumbledore watched the Dementors disappear completely.

Dumbledore said thoughtfully: "Felix, your Patronus opened my eyes. I thought it was a great innovation to develop a Patronus to transmit information. I didn't expect you to think of swallowing Dementors."

Felix blinked, "It was just a flash of inspiration for me, Headmaster. But the effect is really good."

In the stadium, Professor McGonagall and Madam Hooch had already left with Harry, followed by the demoralized Gryffindor players.

Just now, Madam Hooch announced that Hufflepuff had won.

The young wizards left one after another, but many of them were still staring at the podium where Felix was, talking to each other. Even though he couldn't hear the sound, Felix could roughly guess what they wanted to say.

"Will you go to see Harry, Dumbledore?"

"I trust Minerva and Poppy. What about you, Felix?"

"I trust Weasley and Granger."

Dumbledore and Felix smiled respectively. After a while, Felix suddenly thought of something: "I remember that Harry's broom seemed to have been blown away by the wind?"

Dumbledore said uncertainly: "It should be found back..."

"Yeah, it can't be lost."
