Before he knew it, Felix had finished reading all the content.

"Professor?" Hermione looked over.

She interrupted the screen and turned to discuss some questions in the theory.

"I read in the book, "Wands and Wizards", a point that is repeatedly mentioned, 'The wand is alive', how should this sentence be understood?"

"Well... I haven't done much research on this aspect, I can only talk about it in general."

"Of course." Hermione blinked and said in a relaxed tone.

"Every wand is unique. Even if the materials and sizes of them are exactly the same, the effects they can show in the hands of different people are completely different."

"Is it because of the owner of the wand?" Hermione guessed.

"Yes, I personally think that the wands displayed in the store are only half-finished, and they are eager to obtain their own completeness."

Hermione raised her head and stared at Felix. This is a fresh point of view.

Felix explained: "The characteristics of the wood of the wand and the characteristics of the magical creatures from which the wand core comes make the wand extremely varied, but there is another characteristic that cannot be ignored, that is, the owner of the wand itself."

"Rather than saying that the wand is alive, I prefer to believe that the characteristics of the wand body, the wand core, and the owner are combined together to make the wand complete and exert its true power."

"So, this is the theoretical support for 'the wand chooses the wizard'? In order to make itself complete, when the wand body and the wand core are fixed, it is more willing to choose an ideal owner that matches itself?" Hermione followed his thoughts. "

This is a family opinion." Felix said modestly, and then added,

"Moreover, for young wizards, getting a suitable wand is only the first step. The wand and the owner will partner with each other, learn from each other, promote each other, and constantly cultivate this tacit understanding in the future."

"We can understand it this way, the experience of each wand is different."

"But, professor, I heard that some wands will betray their owners?" Hermione asked cautiously.

Felix's expression became serious. "This situation is rare. Even a wand with a bad reputation or a more perverse one will not become alienated from its owner because of one or two failures. The confrontation on campus will not reach this level..." "

But this situation must exist, right?" Hermione asked.

"Indeed. I think the reasons are varied: some have a bad relationship between the owner and the wand; some are naturally sensitive and worship the strong; some are because the 'failure' has too much impact on the owner, deepening the rift."

"However, in terms of the core material alone, unicorn hair is indeed more loyal, while dragon heartstrings are a little too active. They may 'temporarily' succumb to powerful enemies."

"Temporarily?"

"For example, if such a wand is forcibly taken away by the enemy, you can still use it as usual if you retrieve it in time."

"This, this is..." the little witch said in surprise.

"Miss Granger, what we are discussing is too far away from your world." Felix ended the topic.

In fact, Felix believed that the conditions for the change of ownership of a wand were extremely harsh, at least including one of "being completely defeated in a malicious confrontation", which was the conclusion he had drawn from some dark wizards.

That was how Felix's spare wands came from.

But even so, these wands could only be used as temporary emergency wands at best. They were not his own wands, and there would be various restrictions on casting spells.

From the examples of Ron and Neville, there might also be such a situation of "willing transfer", but he had not experienced it personally.

"Granger, let's discuss your transformation of the beaded bag. I originally thought that you would complete it in the next school year."

...

Felix's new book was also on the agenda. In order to expand his influence, he chose to complete two books at the same time. One was for young wizards in preparation, with a large number of dynamic pictures as the main content, supplemented by vivid and interesting storylines.

The other was a popular science topic for adult wizards, using the most rigorous logic and words to explain the most superficial underlying technology in the Muggle world.

After completing part of the manuscript, Felix had the illusion of explaining addition, subtraction, multiplication and division to a mentally retarded person, which made him want to give up for a while.

However, some of the readers he selected gave good feedback .

Belby looked at the manuscript. The first picture was a boiling kettle with hot steam constantly gushing out of the mouth of the kettle; the second picture was a pipe connected from the kettle, and the steam flowed through the pipe to a windmill at the other end; the third picture was the windmill spinning rapidly driven by the steam.

The next picture was a hand-painted version, which looked more abstract: a huge kettle was mounted on a train, connected to the wheels through a pipe, and the train started...

In order to make the whole process more straightforward, Felix deliberately marked the color of the steam very conspicuously, which looked like a train carrying a fanged kettle monster, constantly spraying venom.

"Is this what Muggles call a steam engine? They use it to drive trains?" Belby said excitedly, "You know a lot, Felix!"

Three days before the end of the school year, Felix received an invitation letter signed by the "International Confederation of Wizards". This is an organization similar to the United Nations, except that the members are all magic ministries of various countries.

"Why did they come to me?"

Felix opened the letter and raised his head after a moment. "It turned out that an organization under the International Confederation of Wizards invited me to Paris for a meeting. Muggle Research Group? Tsk, I have never heard of it. It can't be newly established in recent years..."

From the more formal words of the invitation letter, Felix could judge that this research group adopted the strategy of casting a wide net and catching more fish. Maybe even a slightly famous Muggle research expert would be invited.

The next day, he found an opportunity to ask Professor Bubbaji, and the feedback he got was as he expected. She also received an invitation.

"You too?" Bubbage looked at him with wide eyes, "Oh, of course you are qualified. I mean, you are too young, I didn't think of it before."

"Professor Bubbage, do you know where this so-called research group came from?"

"I do know a little bit," Bubbage said, "It seems to be a topic led by the US Ministry of Magic, dealing with crises and so on. It's all old stuff, you know, they are always sensitive to Muggle issues."

Felix nodded thoughtfully.

Then the two agreed to meet in Paris and left separately.

He also wanted to see how the "experts" of other countries viewed the Muggle problem.

In the next two days, Felix dealt with various chores: assigning holiday homework to the little wizards, bidding farewell to Belby with other professors, applying to Dumbledore to stay in school, attending the school dinner...

In front of the station, the little wizards boarded the train happily, and Felix watched silently in the corner.

The most conspicuous was the tall figure of Marcus Flint, who had been hiding from him since the exam;

the second was Clemmy Vera, who wore large glasses. She immediately found Felix after the exam, hoping to maintain communication after graduation and accept his ancient magic guidance;

several other graduates also expressed similar wishes, and Felix did not refuse.

In addition, the young wizards who impressed him this year appeared one by one:

Albert Balk, Percy, Penelope, Geoffrey, Pete Seldon, Warren Pardis, the twins, Cedric, Harry Potter, Ron Weasley, Hermione Granger, Luna Lovegood...

He also saw the somewhat depressed Draco Malfoy. Felix was silent in his heart. He already knew that Lucius had struggled several times, but was still kicked out of the school board. His son was inevitably affected.

Felix watched the Hogwarts Express whizzing away.

When the shadow of the train disappeared from his sight, he turned and left the platform.
