"Please come in, Filius. As it happens, I have something to discuss with you. ”

Dumbledore replied with a loud voice, and the magically sealed oak door made a soft creak and slowly opened.

A wizard who was so small that he looked cute was waiting at the door, and even without Dumbledore's introduction, Elena instantly corresponded to the identity of the visitor - Felius Flitwick, Professor of Charms at Hogwarts School of Witchcraft and Wizardry, and Head of Ravenclaw House.

"There's something wrong with the door knocker at Ravenclaw House, oh, sorry...... Am I here at the wrong time?"

Professor Flitwick walked briskly into the Chancellor's office and spoke quickly.

In the middle of speaking, Flitwick looked up and saw the little silver-haired witch leisurely drinking black tea, and the sumptuous desserts on Dumbledore's table, and stopped talking abruptly, his expression a little embarrassed.

"It's okay, I'm just rewarding Miss Elena with an extra dessert - because of that beautiful [fluorescent flash], you've probably heard Minerva say it. ”

Dumbledore shook his head disapprovingly and replied with a smile, while secretly winking at Elena.

Elena instantly put down her teacup in understanding, stood up from her chair, and gracefully bowed, "Thank you, Professor Dumbledore, for your hospitality. So, I'll go back to the lounge and go to bed. ”

"Ah, yes, yes. ”

The little man Flitwick nodded excitedly and glanced approvingly at Elena in front of him, "A noble and kind character, which is more appreciated than the spell itself. I'm looking forward to seeing you in class, Miss Elena. ”

At this, Flitwick had a slightly embarrassed look on his face, since he had been teaching at Hogwarts in 1970, he had never seen a class of Ravenclaw students like this year, who had to be stranded in droves at the door of the common room on the first day of school because they couldn't answer the knocker question.

"Me too, esteemed Professor Flitwick. In fact, I've accumulated quite a few spell questions that I need to ask you, such as [Shrink Speed] and [Zoom Speed] ......"

Although Flitwick was only a little over a meter tall, this did not affect Elena's respect for the Ravenclaw Abbot, not least because magic spells were a core skill of every wizard.

What's more, the Charms class itself is one of the few systematic law summary courses in the wizarding world, which groped out a solidified [magic black box] between the disorderly wand swing and the will of words, and built the current prosperous magic world.

"Oh, actually, these two spells are very simple, their difficulty is not in the gesture ......" Referring to the area he is good at, especially the questioner is still a good student who he is particularly optimistic about, Professor Flitwick became even happier, raised his finger, and was about to explain a little.

"Ahem, when it comes to spells, I'd suggest you leave it for later. Now, the most important thing you need to do is to hurry back to your dorm room and get a good night's rest. ”

Seeing that the Headmaster's office was about to turn into a makeshift Charms classroom, Dumbledore glared at Elena, couldn't help but cough lightly, interrupted Flitwick's words, and redirected the conversation to where Flitwick entered, "So, Filius, it looks like you have some more difficult problems with your bronze knocker?"

"I've seen it, and it's not too difficult. ”

Speaking of this again, Flitwick's face instantly fell, and he waved his hand a little embarrassedly, "It's just a simple arithmetic problem deformation, it's just a little strange." However, it is the pride and rule of Ravenclaw College that you cannot enter the common room without answering the questions. ”

"Strange arithmetic problem? Isn't that supposed to be easy to get into? Dumbledore was curious.

As Headmaster, Dumbledore was naturally aware of the unique method of entering the common room of Ravenclaw House, and only needed to correctly answer the questions posed by the eaglesbill bronze knocker to be able to enter successfully.

Theoretically, the bronze knocker asks the same question for a period of time, so usually only one student needs to answer it before everyone can enter the lounge.

"That's right, there's something strange about today's knocker. In a sense, there's really only one problem with the repetition, but there are a few small details that keep changing. ”

Professor Flitwick scratched his hair in annoyance, sighed, and said, "Let's say put the rabbit and the raven in the same cage, tell them that there are thirty-eight heads and ninety-six legs, and then ask how many the ravens and rabbits are. However, this number changes every time a student comes in......"

"It's very simple, ten rabbits, twenty-eight ravens. ”

Elena, who had staggered to the door, heard this, a hint of cunning flashed in her eyes, and she turned around excitedly and completed the answer in an instant.

"Hey, have you seen this question before, how can it be so fast?"

Flitwick's eyes widened in surprise and he blurted out that while it wasn't a difficult question in his opinion, it wasn't easy enough to be answered in less than a second.

"Eat. Oh no, I mean they just need to lift both of their front legs, and the rest are all rabbit hind legs. ”

Elena spread her hands and said with a look of course, blinking cutely, "Am I not right?"

"No, you have a point. ”

Flitwick was slightly stunned, thought about it carefully, and looked at the silver-haired little Lori's eyes a little more kindly, "Good at thinking outside the rules, this is the quality we have always advocated, not just knowledge." Oh, I wish you had joined Ravenclaw College. At this, Flitwick frowned.

When you think about it this way, there is nothing wrong with the practice of the knocker, and it is still firmly committed to the mission given to it by the Lady Rowena Ravenclaw.

"Professor Dumbledore, I'm sorry, maybe our house needs to apply for some sleeping bags. ”

Professor Flitwick looked up and said with a determined look in his eyes - it wasn't the knocker that needed to be changed, it was the way the students were thinking, and since the first-year Hufflepuff College students were able to answer questions instantly, then the Ravenclaw students had no reason to complain.

“......”

Dumbledore glanced at the little silver-haired witch who had disappeared behind the oak door, twitched the corners of his mouth, and nodded silently.

His instincts told him that there was a good chance that this matter had something to do with this little guy, but since Flitwick, as the head of the academy, had already made a decision, and he was only guessing, it was naturally difficult to refute.

"Well, if Filius you insist. Dumbledore shrugged, not intending to delve too much into the matter, then looked at Professor Flitwick with a serious face and said in a solemn tone.

"In addition, there is a more important matter, although it is not too early, but it may be necessary to gather the professors. ”

"In relation to the Hogwarts Special Time Adjustment Regulations, we may need to make some changes to our teaching protocol. In between, I added a pre-school preparation course for the young wizards, and I thought about it for a while, and there were many benefits. For example, it is conducive to breaking down the barriers between the academy, improving the willpower and accuracy of young people, and strengthening their physique......"
