At the end of the banquet, Felix stood up with his own firecracker hat and prepared to leave. He saw that Hermione did not leave with her companions, but stayed alone.

"What's the matter, Miss Granger?" He thought Hermione was looking for him.

"Oh, Professor," she hesitated, "I have something to say to Professor McGonagall."

"Is that so..." Felix nodded, "Then I'll go first. By the way, I like the music box you gave me. It doesn't seem to be a simple alchemical product?"

Hermione's worried expression melted away, and she said happily, "I brought it from home. I used the original mechanical structure to recast the spell. For the music part, I referred to the Parseltongue scroll. The magic circuit that stores sound on it is very useful..."

Felix understood. After the Chamber of Secrets incident last year, Harry still spent a few days to complete the pronunciation of Parseltongue. After sorting it out, Felix converted the corresponding syllables into a book and saved it in the thinking hut.

For a while, he did see Hermione playing with the scroll and asked him some production techniques...

Back in the office, he took the time to reply to a few letters, and one of the formal official letters caught his attention.

"It's actually a letter from the Ministry of Magic."

Felix looked at the logo on the letter and wondered what it might contain. Could it be his thesis on memory therapy? But he had just sent it yesterday. When did the Ministry of Magic react so quickly?

He opened the letter and first glanced at the signature at the bottom, which was Walsh Cedric from the Office of the Minister of Magic's Advisory Office. Then he read the main text.

"Dear Mr. Hep: Some of my colleagues have noticed that your new book, 'Magic in the Muggle World', has been listed as a recommended book by the Ministries of Magic of twelve countries. Together with your two previous monographs on Muggle issues, it shows that you have a very deep understanding of Muggles. We sincerely invite you to give an internal speech to the members of the Ministry of Magic...

...

The time is tentatively scheduled for the first Thursday after the Christmas holiday, at 2 pm, in Reception Room No. 2. If you have any objections or the time is inconvenient, please contact me in time.

Yours faithfully

, Walsh Cedric, Office of the Minister of Magic's Advisor."

Below is a long list of departments. If he accepts, the personnel in these departments will be the audience of his speech, including: Muggle Issues Mediation Committee, Muggle Liaison Office, Department for the Prohibition of Abuse of Muggle Artifacts, Team for Reversing Accidental Magic Events, Memory Cancellation Command, and interested people.

"That's reasonable. They are departments that often deal with ordinary people."

Felix thought for a moment. He was still willing to promote his own ideas, and he also wanted to know more about the actual situation of the Ministry of Magic. Among the people he had dealt with so far, Fudge was a standard politician, Umbridge was no less disgusting, and Kingsley Shacklebolt was calm and capable.

As for the rest, he either didn't know them or had only communicated with them through letters, so he couldn't form an accurate judgment.

He took out a piece of parchment and wrote: Dear Mr. Cedric, I am very happy to accept your invitation, but I hope to move it to Friday, because I don't have classes that afternoon... After

the letter was sent, all that was left was waiting. In the last few days of the holiday, he didn't stay in the library or study magic creations in the office, but developed a new habit.

There were always a few magic symbols on his hand, only the size of his little finger, and he would pick them up and play with them from time to time, and even eat and sleep as much as possible.

At this point, simply increasing the number of magic runes was no longer effective. He did not have a deep understanding of the ancient magic runes he had learned from many ancient books and alchemical items.

He decided to take time to organize what he had learned. If he could complete a magic rune book, it would definitely be better than mastering hundreds of new practical magic runes.

He also visited several ancient magic rune experts. He had very few friends in this area. Even Tofty, who was the most talkative, had a very limited understanding of this area.

In Felix's opinion, he might as well pretend to be an alchemist and mix in the alchemical circle. Nick Flamel had introduced several people to him before, and he had written several letters to express his ideas for communication, but later he gradually faded away because the focus of both parties was completely different, and it always felt awkward to communicate.

Alchemists pay more attention to the selection and proportion of alchemical materials, as well as the fusion of different properties. A rare formula may be sold at a sky-high price or become a secret. They also pay attention to the application skills of alchemical symbols, especially the unique way to achieve functions.

Felix exchanged some knowledge with them and then maintained the communication at a lower frequency.

He was not in a hurry. If there was no suitable circle, he would build one himself: eight or nine students who graduated last year still kept in touch with him through letters, and the girl named Vera was the most positive.

She has become a curse breaker at Gringotts. Curse breaker is a very dangerous and serious profession. They may be killed by ancient evil spells, poison spells or curses at work, but the corresponding remuneration is also very generous.

Clemmy Vera wrote to tell him that she is currently working in Egypt, where there are a large number of ancient tombs and historical relics, and her colleagues are also very friendly.

She even found an application scenario for practical magic runes. Many ancient defenses and traps are inseparable from alchemy, and practical magic runes have superior magical performance compared to other alchemical symbols, and are often chosen by ancient wizards as the core of the entire defense and counterattack system.

In a recent operation, Vera accidentally discovered that a practical magic rune was hidden in the decorative pattern in the pit. She used it to avoid a sinister curse and successfully became a regular employee.

Felix was generous in giving advice. In his reply, he pointed out that for some alchemical physical traps that were not very aggressive but difficult to crack for the time being, you can try to build a magic loop to draw out the magic power and make it quickly run out of energy.

...

On the other hand, Harry, Ron and Hermione were not idle either. Since Hagrid wrote to Professor Kettleburn for help, they would go to Hagrid's hut every day to see how things were going.

Having something to do also reduced Harry's resentment towards Hermione from the side. He knew that Hermione meant well, but the Firebolt he had just received was taken away by Professor McGonagall to check for possible dark magic and curses, and he had to endure the old Comet series, which made him feel very aggrieved.

It was not until the beginning of the school year that Hagrid finally received a reply.

"Read it quickly, Hagrid, read it quickly!" Harry said impatiently.

Hagrid tore open the letter and cleared his throat. "Hagrid, I'm glad to hear from you. I sympathize with what happened to Barcobeak, but there's nothing I can do. I don't have any connections in the Ministry of Magic. You can't expect an old man who has been detained 62 times and was rewarded with a permanent position before retirement to have any good relationships with others, unless you want to make one or two troll friends."

Harry and the other two had strange expressions. They felt sorry that Professor Kettleburn couldn't help, but they couldn't help laughing at his witty and humorous self-deprecation. They looked like they wanted to laugh but were trying hard to hold it back. Ron's eyebrows were about to fly to his forehead.

"Then what should we do..."

"Don't worry, there's more to come." Hagrid said, "I can't continue reading. I recommend someone to you. He has enough prestige in the field of magical creatures, and it just so happens that he is very interested in hippogriffs. It is said that he was influenced by his mother. I'll attach the address. You can write to him in the near future. I will also write a letter to explain the situation. Yours faithfully, Sylvanus Kettleburn." Hagrid finished reading the letter and looked up at them.

"Who is it? Who is he recommending?" Hermione asked hoarsely. She had a cold recently.

Hagrid lowered his head again, looked at the bottom of the letter, and read out a name with his eyes wide open, "Newt Scamander."
