Hogwarts: I am Harry's eldest cousin

In the Defense Against the Dark Arts class, Professor Lupin looked a little helpless as he watched the silver filamentous substance spurting out of the tips of the young wizards' wands.

Even with his personal instruction, the students' learning progress was really disappointing.

This is how high-end spells are learned. In addition to hard work and instruction from famous teachers, a certain level of talent is also required.

This is also why professors in magic schools rarely teach high-end spell knowledge.

"Professor, I think you need a teaching aid."

Dudley believes that talent problems can be compensated for in other areas, and he believes that the best way to learn is through actual combat.

"Teaching aids?" The first thing Professor Lupin thought of was Dementors.

But now the relationship between Dementors and wizards outside has reached a freezing point because of the Quidditch game, and Lupin is not bold enough to ask others to be his sparring partners.

"I happen to have a teaching aid here."

As he spoke, a white light flashed, a cold and eerie atmosphere spread out, and a monster in a tattered cloak gradually emerged.

"Dementors!"

Lupin picked up the wand and looked at the thing with caution.

Dudley shook his head and said firmly and forcefully, "No, it's a Boggart."

Lupin was stunned, thinking he had made a mistake, so he carefully identified the other party and found that it did not have any characteristics of a Boggart at all. It was definitely a Dementor.

"Boggart!" Dudley repeated.

Hearing Dudley's affirmative answer, Lupin confirmed it again with some uncertainty. With his many years of experience dealing with dark creatures, he was sure.

Isn't this obviously a Dementor?

Dudley answered for the third time, still in a very certain tone: "It's a Boggart, a Boggart that was confounded and turned into a Dementor."

Chapter 222 Harry, stop it, you're going to kill the Dementor

"Professor Lupin, Dementors do not fall into the category of magical creatures. They are unwilling to obey humans, even wizards, and they are more of a cooperation with the Ministry of Magic."

Dudley ordered, trying to add to his persuasiveness.

"Pour me a glass of water."

The Boggart, which looked like a Dementor to Lupin, floated aside very obediently, poured a glass of water and handed it to Dudley.

Dudley took the cup but put it aside without drinking.

"Look, it really is a Boggart"

Lupin completely ignored Dudley's explanation. He kept his eyes on the cup and saw that the water in the cup was decaying at a speed visible to the naked eye. In just a few seconds, it had become turbid and a layer of frost had formed on it.

Lupin: ???

'Are you kidding me? Isn't this a typical Dementor trait?'

"Professor, the Dementors are outside the castle, searching for Sirius. There is no way they would be in the castle, and there is no reason for them to be there."

Dudley's sudden words startled Lupin.

Having wandered around for many years, he understood what Dudley meant.

Indeed, Dementors cannot appear in Hogwarts Castle, and there are no Dementors in the castle, so this is a Boggart.

In fact, it doesn’t matter whether it is a Dementor or a Boggart. What matters is what is needed in the Defense Against the Dark Arts class.

"Can it really do the job? It won't attack?" Lupin looked at the Boggart with a little concern.

He was answered by Dudley's confident tone.

"Don't worry, it will be a qualified teaching aid."

Those that fail have become the 'philosopher's stone'.

Didn't Dudley catch more than 30 of them during the Quidditch match? Those didn't fall into the category of magical creatures, and although they couldn't be tamed by system skills, Dudley used the most primitive and simplest taming method - physical taming.

This was the only one left from the many he caught that day.

Facts have proved that low IQ also has its advantages. At least after physical domestication, they will basically not betray.

Dudley named the only remaining one the Eye of Evil.

Well, a Boggart named Eyes that was confounded and turned into a Dementor.

"As long as it cooperates, I think our teaching progress will be much faster."

Lupin nodded.

Practice is always the best and fastest way to learn.

"Then who is willing to be the first challenger?" Lupin turned to look at the other young wizards.

He needed a demonstration, preferably a young wizard who was almost able to master the Patronus Charm.

The little wizards looked at each other, but no one was the first to step forward.

Dementors. Even if they are transformed from Boggarts, they are definitely not easy to deal with.

There is a certain degree of risk, and it is more dangerous than the dark magic creatures in Professor Lupin's previous practical classes.

Draco looked around and felt that he should stand up. His Patronus Charm was just a little bit away from being completed. Was there any young wizard present who was more suitable than him?

Malfoy should be the first.

So Draco cleared his throat and was about to speak: "Ahem. Professor, I..."

"Let me do it." Harry stood up first, ahead of Draco.

Like Draco, Harry's Patronus Charm was also basically complete.

Lupin chose Harry without thinking: "Very good, Harry, then you will demonstrate to everyone."

Lupin is very concerned about James' child.

He was very good at dealing with Dark Magic creatures, and his mastery of the content in every Defense Against the Dark Arts class was second only to Dudley.

"Stand there."

Lupin made way for Harry, leaving him plenty of room.

"Remember Harry, when you cast the Patronus Charm you must concentrate and do your best to remember something happy."

After repeatedly stressing to Harry how to cast the Patronus Charm, Lupin stepped aside so that Harry could face the Dementors.

Dudley nodded, and the Dementor came floating in. When it came to Harry, the lights around the classroom suddenly flickered and went out. The little wizards held their breath and stretched their necks to stare at Harry.

"It is really difficult for Mr. Potter, a dark wizard, to cast the Patronus Charm. If he were to use the three unforgivable curses, Mr. Potter would definitely win."

The little Slytherin wizards thought to themselves.

Harry took a deep breath, the bone-chilling coldness hit him and the breath he exhaled began to turn into white mist.

'Think of happy things.'

Harry chanted in his mind and slowly raised his wand.

He slowly closed his eyes, his brain began to work rapidly, and the memories in his mind flashed before his eyes like pictures.

Finally, it froze on a few pictures and Harry chanted the Patronus Charm at this time.

"Call the gods to protect you!"

The first picture.

When he was huddled in a shabby hut with other abducted children and feeling hopeless, Dudley, like a hero, kicked open the door and came up to him.

The second picture.

A brand new cottage, redecorated his own room

The third picture.

The zoo at the age of eleven, the sweet chocolate ice cream, and Dudley acting as an orangutan. Those were his happiest days.

The fourth picture.

In the seaside cottage, being hugged by Aunt Petunia, feeling the warmth of her mother.

The fifth picture.

Dudley chose to build a castle in the old Potter house and he also had a room in the castle.

There are many similar pictures.

Every time a picture appeared, more silver threads appeared at the tip of the magic wand. The countless silver threads became more solid, and the image of the patronus became more concrete.

The young wizards stared at Harry without even blinking. This was the first time they saw the true appearance of the Patronus up close.

Harry was completely absorbed in the memories.

"Stop, Harry, stop."

A slightly anxious voice seemed to ring in my ears.

Harry turned a deaf ear to it.

'This must be a trick of the Dementors.'

He knew that Dementors could suck happiness out of people and bring back bad memories.

So Harry not only did not stop but increased his output.

Until someone shook him hard a few times and pulled him back from his memories.

"If you don't stop, the Dementors... cough Boggarts will be killed."

It was Lupin. Professor Lupin looked at Harry helplessly.

He really didn't expect that Harry would succeed in one try, and the Patronus was so powerful that it almost blew up the Dementor directly.

No one else has used this sparring partner yet.

Standing before the Dementor was Harry's fully formed Patronus.

A giant silver gorilla

Exactly the same one I had seen in London Zoo when I was eleven.

The Dementor, who had been standing right opposite Harry, was now held in the hand of Harry's Patronus. One hand grasped the rag on the Dementor's body and lifted it up like a collar, while the other hand was raising a fist. The Dementor tilted his head to one side with a weak look on his face.

Chapter 223: Supercars of the Wizarding World

Harry quickly retracted his wand, and the Patronus dissipated. He looked at the Dementor that was beaten half to death with an apologetic look on his face.

"Harry, congratulations, you have completely mastered the Patronus Charm."

It was Dudley who spoke, and he immediately gave Harry his sincere blessings.

"It's just a Boggart that was confounded and turned into a Dementor. If it's gone, I can just catch another one. There are plenty of these things out there anyway."

Lupin's eyelids twitched at Dudley's nonchalant tone.

That's a Dementor. A very dangerous dark magic creature. It makes it sound like catching a Dementor is as easy as catching a goblin on the roadside.

'What kind of family is Lily's sister from? Why haven't I heard James and Lily mention it before?'

Of course Lupin wouldn't listen to James mentioning this, because when he and Lily first met Petunia, they almost had a conflict with Vernon.

Dudley took out a potion from his pocket and threw it on the Dementor, and soon the Dementor recovered from its injuries.

"Look everyone, Harry has mastered the essence of the Patronus Charm. Is there anyone willing to come up next?" Lupin asked encouragingly.

With Harry's good start, young wizards signed up enthusiastically.

Even with such a great teaching aid, the class time is limited and not all little wizards can put it into practice, so the sooner you get forward the better.

Not everyone is called Harry Potter, and not everyone has Harry's talents.

Most of the young wizards are still unable to form a Patronus and can only release some silver threads. This level of Patronus Charm is basically ineffective against Dementors.

The little wizards who participated enthusiastically walked off the stage with paler faces than each other.
