The Muggle-Repelling Charm can block the perception of Muggles, causing them to ignore certain things subconsciously.
In the same way, the Fidelius Charm can also confuse people's perceptions, causing them to ignore or even forget certain things.
However, although these two spells have similar effects, they are fundamentally different.
The former simply blocks perception, while the latter turns something into the concept of a 'secret' and hides it in a person's soul so that everyone forgets about it.
Andy couldn't help but feel a little curious.
Long, long ago, had a wizard used this magic to make the whole world forget something?
Was that possible?
Andy felt that it was possible!
Andy found out that the effect of the Fidelius Charm does not dissipate with the death of the secret keeper.
If the secret keeper of the Fidelius Charm dies, then the person who knows the secret becomes the new secret keeper.
There will be as many secret keepers as there are people who know the secret.
"What's wrong with him?" Helen couldn't help but worry as she watched Andy standing there in a daze.
Hermione was slightly helpless. "Don't worry about him! Whenever he comes across a magic-related problem, he always acts like this. Just let him think it over on his own; when he sorts it out, he'll be fine."
Kyle and Helen exchanged glances at this.
Although they had long known that their son's obsession with magic ran deep, they had never imagined it would be to this extent.
"I'm fine..."
"Let's call it a day." Andy shrugged and said, "Write to me when you've found a house. We can't be out for too long, so we'll head back now."
"Oh, and we should let both sides of grandparents know. With the Dark Lord's return, the wizarding world will become very dangerous."
Kyle nodded and said, "Don't worry, there's nothing to worry about here. You should also be careful at Hogwarts. Dumbledore is getting old, and Hogwarts has not been peaceful in recent years."
"I will!"
Andy said, holding out his hand to ask Hermione to take it, before continuing, "We'll go back first then."
"See you in the summer!" Helen smiled.
"See you in the summer!" Andy waved.
Pop!
They used the Apparition spell and disappeared.
***
Since their family's safety was at stake, Kyle and Helen acted swiftly.
Just one day later, Andy received a letter from home.
Taking advantage of the night, Andy left Hogwarts again. Outside a villa, he cast the Fidelius Charm, which concealed the entire villa's location.
According to Kyle, Andy's paternal grandparents, his maternal grandparents, and his aunt will be staying here for the time being.
Until the war is over.
Andy naturally has no objection to this.
With war looming, the safety of his family is naturally the most important thing to consider.
What's more, Andy is also planning to take advantage of the war to gain some influence and fame. While this is a good thing, it will also pose certain risks to his family.
***
Once he had taken care of the family, Andy then turned his attention to his own interests.
The first thing on the agenda was Harry.
Harry was easily influenced; with just a few words, Andy could see the excitement in his eyes, and he couldn't even wait to have a dream date with Voldemort.
Andy loved the way his eyes sparkled with innocence and stupidity!
However, a dream 'date' was not something that could be forced; it depended on Voldemort's willingness.
So the only thing Andy could do next was wait.
Saturday, 14th May.
Today is the second Saturday of May and also the first day of the Duelling Club.
Since the morning, Hogwarts has been in a sea of carnival.
Everyone is very excited.
Gryffindor even declared in public that they would crush Slytherin today.
Slytherin naturally refused to be outdone, and they decided to give Gryffindor a hard time. Some people even said that if the professors agreed, they would be willing to have a house war with Gryffindor.
Hufflepuff introduced Cedric very stealthily, declaring that Cedric was invincible in duels.
When Cedric heard this, he claimed that he had not been feeling well since the morning—there was no way he could defeat Andy.
As for Andy, who is in Ravenclaw...
Well, Andy is now the face of Ravenclaw.
The Ravenclaw wizards are bragging about Andy everywhere, saying that Andy can defeat everyone with the Patronus Charm alone.
Andy modestly responded that this was not a rumour!
The young wizards are thrilled, and the professors are very serious.
Especially Snape!
According to the plan, Professor Lupin would be in charge of the Duelling Club. In each session, a professor would cooperate with Professor Lupin to teach duelling.
At the strong request of a certain professor, Snape would be the first professor to cooperate in teaching.
As soon as this news was announced, the Gryffindors and Slytherins immediately became exhilarated.
They kept arguing about whether Professor Lupin was better or Professor Snape was better.
As the clock struck two o'clock, everyone was waiting with bated breath.
By now, the Great Hall had been transformed into a duelling arena.
The young wizards stood in a circle against the walls of the empty hall.
In the middle of the hall were four long platforms—duelling platforms.
At exactly two o'clock, Professor Lupin and Professor Snape arrived in the hall together, and the crowd immediately began to cheer loudly.
They had been waiting a long time.
Professor Flitwick was also there, but Professor Flitwick was standing in the Ravenclaw crowd at the moment. Due to his height, not many people noticed him.
Walking to the centre of the hall, Professor Lupin glanced over at Professor Snape.
Snape ignored him with a cold face.
Professor Lupin smiled kindly without being bothered and leapt onto a platform first, looking around and saying, "Welcome to the Duelling Club!"
"I won't bore you with unnecessary words; I'm sure you've been waiting impatiently."
"However, Professor Snape and I agree that before formally teaching you how to duel, it is necessary for you to see what a real wizard duel is like."
As he said this, Professor Lupin turned to look at Professor Snape.
Severus, come up here!
The crowd cheered, too. This was the ultimate showdown between Gryffindor and Slytherin.
From the audience, Professor Flitwick clenched his fists; he also wanted to go up!
Snape sneered and said indifferently, "Since it's meant to teach the students, it's better to find a student. This way, it will make those idiots realise the gap between them and the professor even more."
As he spoke, Snape glanced around, quickly locking into Andy's position.
Snape pointed his finger and said coldly, "Collins, you go up!"
Professor Lupin: "..."
