"Oh, Professor Lemay, do you really plan to live in the common room?"

At the long table at Ravenclaw College, Professor Flitwick hesitated for a few seconds, then said with some concern.

"I mean, Ravenclaw's bronze eagle ring may not be as ...... as you might think Interesting...... It's just a knocker, especially since the Eagle Ring seems a little strange, asking questions that even I find difficult to answer. On the other hand, Hogwarts actually has a special ...... for professors"

"You don't have to be so inhibited, just call me Nicol, Flitwick. ”

Nicol Lemay paused slightly, looked away from the figure who was sneaking away from the Ravenclaw table, raised his eyebrows with interest, turned to look at Professor Flitwick, and smiled.

"Rather than living a routine life, I'm more looking forward to the challenges that will stump me. Besides, if it's an alchemy problem, maybe I can help fix it? Nothing will be boring about Lady Ravenclaw. ”

In fact, when it comes to the Bronze Eagle Ring, there is also a small bet involved.

According to the previous private agreement, if he could answer the Bronze Eagle Ring's question today, then Elena Kaslana would tell him the details of the prophecies of the calamity in their entirety - Nicol Lemay had been a little uneasy since hearing about the future in the girl's mouth, after all, some of the descriptions were too much like the Philosopher's Stone after the loss of control.

Nicol Lemay frowned slightly, and the fragmented information that the girl had described earlier flashed through her mind.

Is it an undead creature called a zombie that has lost its soul and relied only on instinct and physical remains......

If this was really a disaster caused by the Philosopher's Stone he left behind, then as the refiner of the Philosopher's Stone, he naturally couldn't sleep as he had planned - at least until this hidden danger was resolved, he couldn't leave.

Of course, this little bet was only between him and Elena.

In front of Dumbledore, as well as the professors at Hogwarts, there was naturally another logical statement.

"It's really curious...... More than 1,000 years ago, Ms. Rowena Ravenclaw ...... What kind of magic did she put on that ring so that it could constantly renew itself while remaining true to its original intentions...... You should be able to understand how fatal it is for every lover of alchemy......"

Nicol Lemay looked at Professor Flitwick, who was about to speak, and asked politely and softly.

"So, is there anything else inconvenient about that?"

"Hmm...... Since you're insisting—"

Professor Flitwick shrugged his shoulders and didn't hold on.

"All in all, there are a lot of empty rooms in the castle, and you can change your mind at any time. ”

He wasn't worried that the centuries-old wizard wouldn't get used to sleeping, as the head of Ravenclaw House, he actually felt a little sorry for the children of his house, and if he was unlucky, they might have to sleep in the hallway again.

Unlike usual, today's Bronze Eagle Ring is not for students to answer at all.

Dumbledore had already communicated with him in advance before today's dinner began.

As the greatest alchemist of nearly five centuries, Nicol Lemay wanted to be able to "simply communicate" with the legendary Lady Rowena Ravenclaw through the millennia-old bronze knocker – an opportunity that would be enough for a great alchemist like Nicol Lemay.

Naturally, in the face of the Headmaster's request from Hogwarts, the proud Bronze Eagle Ring agreed to this special challenge.

It will follow the tradition and history of Hogwarts and make an exception for Nicol Lemay...... With the help of a little angel who did not want to be named, today's Bronze Eagle Ring has already completed the update and iteration of the basic question bank.

As the professors left their seats, the auditorium was filled with the sound of clattering and ping-pong.

The students rose to their feet and flocked to the double doors leading to their dormitories, where the flow of people was divided into four distinct colors and walked through the foyer and little by little towards the staircase.

"Come this way, Luna. Let's go to Hufflepuff. ”

Elena didn't follow the flow of Ravenclaw to the door, but took Luna's hand and quietly blended into the Hufflepuff House team, "Don't be in a daze, the Eagle Ring will definitely not open tonight, you shouldn't want to sleep in the hallway, right?"

"You can't beat the ...... of an academy"

Luna stood still, quietly glancing at Professor Flitwick at the Ravenclaw College long table, and whispered.

"Even if they don't like you, they're Ravenclaw after all, and there's Professor Nicol Lemay today!

Last night, before Elena returned to the dormitory, Professor Flitwick went to Luna and had a serious conversation for a while.

And to sum up, in fact, I hope that Luna can leave Elena on the Ravenclaw side as much as possible, and not be snatched away by the girls of the other three houses, after all, Elena has been similar to the "fat lady" in Gryffindor since last year, which is almost equivalent to half of the mobile access to the Ravenclaw common room.

"Yes," said Elena, casually coping, "yes, and Nicol Lemay......"

"So it's better to ......"

"But, Professor Flitwick doesn't ask you to do it, does he?"

Elena flicked Luna's little head, glanced at the surprised and speechless little moon, and said helplessly.

"If you're still feeling a little embarrassed, just say I 'invited' you two to Hufflepuff House for the night. Anyway, today is a special case, and because the other party is Nicol Lemay, he won't open the door anyway-"

"Don't keep snapping me on the forehead! or I won't help you deal with Hermione next time!"

Luna clutched her head in pain, her trance-like eyes slightly coming back to her senses, and she blinked in confusion.

"Wait, you just said - we?"

Only then did she notice that in addition to her and Elena, there was also a Ravenclaw girl who did not leave the auditorium with the large group, but stood timidly not far from them, watching the "senior" seniors flirt.

The new Russian student who just entered the school this year seems to have a ...... name Danilova?

"Of course, having people sleep in the hallways just after school starts is not Hogwarts hospitality. Besides, Professor Alexei had specifically instructed him to try to bring little Danny to make more friends if he could. ”

As the child of a nuclear physicist in the former Soviet Union, Danilova may not be too demonic in terms of knowledge for the time being, but some basic mathematical and physical knowledge is still quite solid - compared to Elena, who was born in economics, this little witch from a Russian scientific family is actually more suitable as the first tester of the [magic-science] theory.

Elena explained a few words briefly, beckoned to the little witch not far away, and smiled softly.

"Come here, Danilova. I'll take you on a tour of the Hufflepuff House common room. ”

Soon, the trio made their way to the Hufflepuff table, where they joined Hannah and Hermione, and the five little witches began to walk towards the foyer as planned, explaining the origin of the little tails, gossiping and answering some gossip about Nicol Lemay and the Ravenclaw common room.

"So, you weren't going to let Mr. Nicol Lemay into the common room in the first place?"

Luna Lovegood frowned slightly and asked thoughtfully.

"No, of course then," Elena shook her head, "but not tonight." Not from the point of view of the Lady of Ravenclaw, nor from the point of view of the battle between Beauxbatons and Hogwarts......"

"Beauxbatons School of Witchcraft and Wizardry?" Hermione asked curiously.

"Yes, Mr. Nicol Lemay is not a Hogwarts graduate, he is French. ”

Elena raised her finger and said with a serious expression, "Since a long time ago, there has been a rivalry between the French and English wizarding worlds. Maybe he didn't mean to think so, but if he had the upper hand in the initial encounter, it would have left a less pleasant 'conversation in the air' story for future records of magical history. ”

"But didn't he live more than six hundred years?! What other questions can ......?"

Hannah said in a worried tone as they passed through a door hidden behind a tapestry and began to walk down a narrow staircase towards the castle - Hannah had always been a good Hufflepuff when it came to finding ways in dungeons.

"Yes," Elena said nonchalantly, "but age only allows him to absorb more knowledge, right? Besides, the Bronze Eagle Ring asks questions that can't be answered by magical books alone?You should know what I'm talking about, as the math editor of Contradiction, you know best what the math level of the wizarding world as a whole is like. ”

"But as you said, Professor Nicol Lemay is from France. ”

Hermione shook her head and quickly retorted, "Professor Alexey said in class before that France is the kingdom of mathematics in the non-magical world, and I don't think a famous alchemist would be stumped by the questions you come up with. ”

"That question can't be solved—"

Before Elena could answer, Danilova's timid voice came from behind Hermione.

"However, I think my dad may have some ideas, and their friends and teachers seem to have discussed similar issues at home before, and if they are given some time, they should be able to try to get closer to that answer......

"This does not conform to the logic of the Eagle Ring, which does not ask an unsolvable problem. ”

Luna said earnestly that she had heard many stories about Hogwarts from her father since she was a child.

Among them, the bronze eagle ring in the common room of Ravenclaw House is undoubtedly the easiest part of the game to exist as a short story or a daily test between father and daughter - although the eagle ring of Hogwarts is difficult, it is definitely a solution.

"Of course, in the vast majority of cases, it is exactly what you say. But—"

Elena nodded, shook her fingers from side to side, and continued incomprehensibly.

"Don't forget that the bronze eagle ring at the door of the common room of Ravenclaw College is still essentially the alchemical work of Rowena Ravenclaw, and the knowledge, cognition, and certain concepts built into it are not so much a fixed explanation as there is a message that can be learned and accepted as understood by Lady Ravenclaw. ”

"So, in other words......"

Elena glanced at Hermione, who seemed to understand whether she understood or not, and the corners of her mouth curled slightly.

It can be a conjecture that has not yet been proven, but it is also unfalsifiable. And the proof process, except that the person himself writes it out for you, before the second person can fully answer it, is an unsolvable challenge......"

Just like Fermat's theorem, which has plagued mathematics for centuries.

Pierre de Femat only had to come up with this idea and write on the side of the book - "I have found a wonderful proof, but it is too narrow for me to write." In the questioning of countless mathematicians in later generations, he will always stand in the position of a pioneer, smiling and waiting for people to keep challenging and thinking.

If Elena is not mistaken, according to the original trajectory of the world, the proof of Fermat's theorem will have to wait two years.

Unless someone succeeds in disproving this conjecture, Monsieur Fermat will be forever invincible from the moment of Pierre de Fermat's death, and no one can defeat a soul from the past.

Elena's eyes flickered, remembering the stories she had found in her books over the years.

Whether it's the exchange rate set by Gringotts Wizarding Bank thousands of years ago, or the number of extra-nuclear electrons in Yinsike and Bronze Nat, or the conversations and wishes left by the four founders of Hogwarts in some documents more than a thousand years ago......

"Hogwarts, an ancient magical civilization, is not as simple as people think......"

......

Meanwhile, Nicol Lemay and the Ravenclaw students walked up the spiral ladder to the platform in front of the Ravenclaw common room, tapping lightly on the sleeping bronze eagle ring.

In Nicol Lemay's curious eyes, the bronze eagle ring awoke and opened its mouth to make a soft and pleasant female voice.

"There are four houses at Hogwarts, each with its own color, so can we be bold enough to say that one day in the future ......?"
