Hogwarts has the largest number of house-elves in the wizarding world, with more than two hundred.

In just half a year, the number of house-elves working with Fred and George is almost more than Hogwarts, which is incredible.

The point is that they're all hired, which makes it even more incredible, even if the pay is low.

If the line continues to expand, Fred and George will hire more house-elves.

The two of them had this in mind, and a recent letter to Aven was still discussing borrowing money from Gringotts.

Considering that the war was coming, the uncertainty was too great, and the risks were too high, Evan did not agree to borrow.

Gringotts' money doesn't have to be repaid just because the war comes, and there's no such thing as a debt from the goblins.

His suggestion was to continue to transfer a portion of the production lines that did not require magic to Muggles, as permitted by the law of secrecy.

This will save a lot of costs while expanding productivity, and he wrote to his dad about it.

Fred and George made a lot of money with their protective gear, but at Hogwarts, they were best known for their joke products.

They are now the largest supplier of prank products and are completely legendary in the minds of students.

"How did they get to sell all this stuff to the school?" Harry continued to ask in amazement, "Aren't all owls going to be checked, how can those girls bring aphrodisiacs into the castle?"

"They sent those things as perfume and cough drops, which were part of the owl order service. ”

"Oh, you know so much. ”

Hermione glared at him fiercely, just as she had glared at Evan and at Advanced Potions Making.

"It's all written on the back of the bottle they showed me and Ginny during the summer. "But I'm not going to drug anyone else's drink." ”

"yes, you really don't. "But seriously, if you dome me, I don't mind." ”

Hermione looked up and glared at Evan again, but not for long, as her face quickly turned red.

"Please, you two, I just got out of the torment of Ron and Lavender. Harry pretended to be pleading, "The question now is that Filch is playing tricks, isn't it? These girls can bring things into school if they disguise them!, so why can't Malfoy bring a necklace......

"Oh, Harry, don't mention that again!"

"Ah, why?" Harry asked, "isn't this suspicious? ”

"It's suspicious indeed, but it's also a lame murder. Evan said.

"It's just like Malfoy's style, he doesn't have a lot of brains. Harry didn't give up.

"Well, Harry, look. Hermione sighed and patiently explained, "Probes can detect bad luck charms and hidden charms, right? They are used to detect dark magic and dark magic items, and can detect a powerful spell in a matter of seconds, like the one on the necklace. But anything in the wrong bottle can't be detected, and no spell or secret detector can detect it. Besides, aphrodisiacs are not black magic, and they are not dangerous......"

"You're right. Harry muttered, "This thing sounds dangerous." ”

"The problem now is that all the things in bottles that want to enter the school need Filch to check and determine if they are cough drops or something else, which is fundamentally different from dark magic items like necklaces. "Because we can't use tools, we all know that Filch isn't a very clever wizard, can you tell the difference between ......."

He stopped abruptly, and Harry and Hermione looked up at the same time.

They all heard someone approaching in the dark bookshelves behind them, and the sound of footsteps came from far and near.

After a few seconds or so, Mrs. Pince's vulture face peeked out from the corner, her sunken cheeks, parchment-like skin, and long hooked nose illuminated by the lamp she carried.

"It's time for the library to close, put the borrowed books back ......," she said, her eyes falling on the textbook in front of Harry, and her voice raised sharply, "Oh my God, what did you do with that book?

"It's not from the library, it's my own!" Harry said quickly, picking up the Advanced Potions Making book from his desk, but Mrs. Pince's talon-like hand had already grabbed it.

"Robbery!" she hissed, "blasphemy!

"It's just braille written on the book!" Harry argued, pulling the book back from her hand.

It didn't work, she looked like she was going to have a heart attack and could collapse at any moment.

Evan and Hermione hurriedly packed up their things and grabbed Harry's arm and dragged him away.

"You shouldn't argue with her. ”

"That's right, she'll ban you from the library. Honestly, why do you have to bring that stupid book?"

"It's not my fault that she's screaming. Harry muttered, stopping abruptly and looking up at Evan and Hermione, "Wait, do you think she'll hear us speak ill of Filch......?

Evan and Hermione were stunned for a moment, thinking about it, it seemed really possible.

Mrs. Filch and Mrs. Paces's secret romance, and they seem to have an ulterior relationship with each other.

The three of them made their way to the Gryffindor common room, arguing about the relationship between Filch and Mrs. Bians. This gossip was indeed novel and interesting, but due to the lack of conclusive evidence, it soon could not proceed, and the conversation naturally shifted to the Christmas schedule that would soon follow.

"Ron invited us to the Burrow yesterday, but I declined because of that. Harry said, hesitating for a moment, "Aven, can you let him stay with us?"

He was referring to summoning demons, and they and Dumbledore were acting around this Christmas holiday.

Therefore, Evan and Harry can't leave school and stay at Hogwarts for Christmas.

Then there were Hermione and Elaine, whom Evan had spoken to Dumbledore before, and the Headmaster had agreed to his plan.

"I can't say anything about this, I need Dumbledore's permission, but I don't think since the four of us are going, plus Ron, there shouldn't be a problem. Evan hesitated for a moment, then continued, "The key question is whether he wants to come with us, he barely talks to me, Hermione, Elaine now. ”

"He just hasn't figured it out yet. Harry said, "Don't worry, I'll tell him, and he'll be reconciled with everybody." ”
