Cedric thought about it all night, so much so that when he ate breakfast the next morning, he still looked sleepy.

"What's the solution?" Kyle asked.

"Of course." Cedric said with a relaxed look, "As long as you can lead Gryffindor by 150 points within 20 minutes, the victory will still be ours."

"Is this what you came up with?" Kyle looked at him incredulously. "Twenty minutes and one hundred and fifty points ahead of Gryffindor? Are you still asleep, or did you forget your brain in the dormitory?"

"You've done it before," Cedric said. "Remember, the match against Ravenclaw?"

"That was two years ago!"

Kyle said unhappily, "And that wasn't just my credit. Harris's cooperation was also a factor... Plus, the Ravenclaw team was so weak that they were giving away points, so they were able to lead by such a large margin."

"What's happening now is that Harris has graduated."

Kyle continued, “Also, Fred and George apologized to me in advance after our first game and said they would never let the Bludger leave ten feet away from me.

"Do you understand what this means? There are two of them and goalkeeper Wood. I have to get through at least three people before I can score!"

"But this is the only way." Cedric laughed.

He thought about it all night yesterday and found that the Firebolt was an unsolvable existence... In the face of absolute speed, any tactics seemed pale.

Unless the victory is secured in advance.

"I will make everyone cooperate with you." Cedric said, "The next tactics will be centered around you."

"Okay." Kyle nodded.

After breakfast, several people left the auditorium and went to the classroom to prepare for class.

Today is the day when Professor Lupin's Patronus Charm Club begins. Because people are so excited, their minds are not on the class.

The professors apparently also discovered this, but this was obviously not a big problem for them and could be solved with just one sentence.

"No whispering in class, Mr. Flower, five more points deducted from Slytherin!"

In the Transfiguration class, Professor McGonagall knocked on the table and said seriously, "If any of you are deducted more than ten points in this class, you will be put in detention. Go to the library at 8 o'clock in the evening and clean those bookshelves!"

As soon as Professor McGonagall finished speaking, everyone sat up straight.

Eight o'clock is exactly the time when the club starts, and the library has hundreds of bookshelves... By the time the cleaning is done, the club will probably be over.

"Very good!" Professor McGonagall nodded with satisfaction. "Let's continue with what we were talking about just now. The most important thing about the conversion spell is decisiveness. There can be no hesitation..."

Afterwards, she seemed to have told other professors about this method, so that in the following classes, everyone was very nervous, fearing that they would be left behind and put in solitary confinement that night.

…

And just like that, it was finally eight o'clock.

Some people went to the auditorium early and waited, while some simply did not leave and stayed here after dinner.

When Kyle and his friends arrived, there were already a lot of people there.

The long tables were once again moved to the side. There was not a single cloud to be seen on the enchanted ceiling, and looking up there was a sky full of stars.

At eight o'clock, Professor Lupin walked in on time. It seemed that it was the first time for him to face so many students, and he looked a little nervous.

"Relax, Remus." Professor McGonagall whispered to comfort him, "Just treat it as a normal class."

Not only Professor McGonagall, but also Professor Flitwick and Snape came, as well as Madam Pomfrey from the hospital wing.

This lineup is many times better than last year's Duel Club.

But soon, Kyle knew the reason.

"First of all, I want to ask everyone not to panic."

Professor Lupin put a large box on the ground. "Although some people think that my approach is too risky, I must say that the fastest way to learn the Patronus Charm is to face the Dementors directly."

Everyone stared at the box in front of him, seemed to have guessed something, started talking, and subconsciously stepped back.

A large area soon vacated around Professor Lupin.

He clapped his hands and the box immediately began to shake violently.

The discussions around became louder, and some younger students began to look back towards the door.

"Please don't worry, I won't release it at the first club, and there are several professors here, enough to ensure everyone's safety..."

Professor Lupin had to put his wand to his throat to silence the growing chatter.

"Of course, if you want to leave, I won't stop you. It's your freedom..."

Professor Lupin waved his wand and opened the door to the Great Hall.

Some students hesitated for a moment and then left, but more people chose to stay here.

"It looks like you've already made up your mind."

Professor Lupin said, "Those who want to leave can leave at any time. Those who decide to stay, please keep quiet. We will start learning the Patronus Charm.

First of all, we need to understand this spell. This is a very advanced magic, far beyond the level of ordinary wizards. I can't guarantee that you can all learn it, but I will try my best to teach each of you. "

Because there were so many people, Professor Lupin did not choose someone to answer as he did in class, but explained it himself.

"The Patronus is a positive force, an external manifestation of hope, happiness, and survival... but it cannot feel despair like a real person, so the Dementors cannot do anything to them..."

Professor Lupin cleared his throat and continued, "You must focus all your will on a particularly pleasant moment for this spell to work...

"Remember what I asked you to do before the holiday? Those happy memories... Now I'll give you some time to recall them."

Soon, everyone's expressions began to change.

"The spell is..." Professor Lupin said clearly: "Expecto Patronus!"

"Expect God's Guardian..."

"Now, focus your mind on those pleasant memories and chant the mantra."

According to Professor Lupin's request, everyone did as they were told.

After a while, silvery-white gas began to float in the auditorium, like morning mist.

They piled up above the auditorium, gathering more and more.

"Very good," Professor Lupin said with a smile, "It seems that you have basically mastered it. So, are you ready for further practice?"

"We're ready." Everyone held their breath and held their wands tightly.

Professor Lupin placed his hand on the box and pressed it gently.

The box was not opened, but there were a few small holes.

The student standing at the front faintly heard a long inhale.

A biting chill began to spread, and the silver mist that shrouded the auditorium disappeared in an instant.

Some people began to tremble, and even couldn't hold their wands steadily. They couldn't help but want to escape from here, while others gritted their teeth and began to chant spells louder.

"Expect God's Guardian..."

"Expect God to Guard!"

The silver mist was constantly dissipating, but at the same time new one was replenished.

“Bang!”

After an unknown amount of time, Professor Lupin closed the small holes on the boxes.

The chill also disappeared.
