July 21st, 10 am.

Felix was dressed formally, standing in the fireplace, sprinkling a handful of Floo powder, and shouting "Hogwarts Vice Principal's Office". After a green flame, his figure disappeared. In

the Vice Principal's Office of Hogwarts, Professor McGonagall was sorting school documents with a serious face.

The Transfiguration professor, who was known for her strictness, always had a blank expression on her face, but she was in a good mood at the moment. Gryffindor House won the long-awaited House Cup last school year, which kept the head of Gryffindor House happy until now.

"Boom!"

A cluster of green flames flashed in the fireplace, and a young, polite man stepped out.

Felix looked around and saw that it hadn't changed at all. It's been a long time since I last saw you! He smiled gently at McGonagall: "Professor McGonagall, hello, long time no see." Professor McGonagall pursed

her lips, which meant that her mood was rapidly getting worse, or she was in work mode, "Long time no see, Felix."

Professor McGonagall also taught him and was one of his professors. Her feelings towards this famous student were very complicated, of course not the kind of complicated that Professor Snape had.

Before the long-awaited College Cup, Gryffindor had a painful seven-game losing streak, and this experience had a lot to do with Felix.

Except for the first three years, Felix's learning environment was too bad, which forced him to fight back, so he lost a lot of points. In the following years, after he forced himself to get along with the little snakes, he seemed to finally realize that he was a Slytherin student and should fight for the honor of the college.

And the next few years can be described in one sentence, "Glory to Slytherin".

...

Felix walked forward and looked at his pocket watch, "I hope I didn't miss the interview."

Professor McGonagall was interrupted by her memories, stood up and led him to the principal's office, "Chocolate Frog." She read the password and sent Felix in. Before leaving, she said, "Your books are very good. It seems that you have had a fulfilling three years."

"Thank you, Professor McGonagall." He was slightly stunned, smiled, and then stepped onto the steps.

Three years after graduation, he didn't mess around in vain. Especially after his first job search failed, he thought over and over again, suspecting that his student life was too vigorous, so he followed the advice of Headmaster Dumbledore, "Walk more and see more."

He spent a year wandering around the wizarding world, and the remaining two years stayed in the Muggle world to work, uh, study Muggles.

The results were remarkable. In three years, he wrote three books, two Muggle studies, and one ancient magic rune.

He also accumulated a considerable fortune.

Walking up the long steps, Felix entered the principal's office, which was filled with various books and alchemical products, and on the wall were portraits of successive Hogwarts principals.

On one side of the principal's desk, a phoenix closed its eyes and took a nap.

Dumbledore was studying something at his desk, and the whole office was very quiet.

"Good morning, Headmaster Dumbledore." Felix greeted him. As he spoke, the room suddenly became lively.

The portraits of the principals opened their eyes, looked at Felix, pointed, and whispered.

One of the portraits was extremely exaggerated, "Ha! The best Slytherin is here!"

The man in the portrait had a goatee, thin eyebrows, and was wearing Slytherin robes. He was Phineas Black, who was voted by students as the most unpopular Hogwarts headmaster, and was also from Slytherin.

Felix saluted gracefully.

At this time, Headmaster Dumbledore finally raised his head. He had a very different appearance from ordinary people, with a silver-white beard that dragged long to his chest; his robe was not neatly worn, and he wore a pair of half-moon glasses.

But these were not as good as his eyes. His eyes were very bright, and his blue pupils seemed to be shining.

Felix was a little dazed. Time did not leave too many traces on this headmaster, but it seemed to have left too many traces.

"Ah, ah! It's Felix," Dumbledore stood up and strode over. His movements were very agile. "I have been waiting for you to come."

Felix shook hands with the headmaster a little stiffly. After all, he came to the headmaster's house to apply for a job and was rejected three times.

The two sat on the chairs. Dumbledore looked at him through the thin lenses and waved his wand. "What would you like to drink? Pumpkin juice? Tea?" Then he blinked and said, "I have fresh butter beer here." "

A cup of tea, thank you."

Dumbledore waved his wand lightly, and a cup of steaming tea floated in front of him. Felix took a sip. A bitter taste rushed into his mouth and nose. It was old tea. It seems that the headmaster doesn't drink tea very often.

"The tea that Sybil gave me, although I personally can't taste whether it is good or bad, but according to her, it comes from the far east."

Liar!

Felix complained in his heart, at least one of you two is a liar.

After drinking tea, the conversation began to get down to business.

"Felix, you have done a great job in recent years. I have been reading your works, and I have to say that your research on Muggles is very novel and in-depth... It has given me, an old man, a lot of ideas."

Felix smiled, "Thanks to your advice, the world of Muggles is very wonderful, especially in recent decades, they have developed very fast. As for the works... Maybe it's because I am also a Muggle-born, so I have a better understanding of them."

Dumbledore shook his head, "Your origin cannot erase your efforts. There are many people in the wizarding world who are Muggle-born, but they are not good at Muggle research. At most, they have a deeper understanding of some common sense, but this is far from understanding."

Of course, because I was a pure Muggle in my previous life.

Dumbledore waved his wand and a book flew out from the desk. The title of the book was "The Struggle History of Muggles: A Million Years Ago", which was one of Felix's works. He was a little surprised. It turned out that Dumbledore had been reading his book just now.

"This book is very inspiring to me. I have read it more than once, especially the way you describe the history of science and technology - is that the word? From the perspective of the history of science and technology, how did Muggles develop from beasts step by step over millions of years to the current level? I have to say, this is a miracle."

"You also pointed out that the Muggles' technological level will leap forward at regular intervals, and the intervals are getting shorter and shorter. You even predicted that the next leap is not far away - very inspiring!" Dumbledore praised his book. Felix

said modestly, "This idea was not created by me. In fact, many sociologists in the Muggle world, oh, that is, Muggle scholars who study Muggles, their works have helped me a lot."

Dumbledore said calmly, "Many Muggles are equally wise, but few people in the wizarding world admit this."

"I agree with you, Professor Dumbledore."

Dumbledore then blinked, as if skipping over the previous topic, and said playfully: "So, you must have read a lot of Muggle works? Frankly speaking, many of my Christmas gifts are books, and they seem to think that I prefer books. But in fact, I have read most of them. Compared with that, I prefer a pair of wool socks."

"Of course, if it's a book from the Muggle world, I don't think I will refuse."

A blatant hint...

at least he knows what Christmas gifts should be given...

"Yes, although they have no magic, some of them are willing to spend more than ten years to complete a book, specifically explaining a problem or a theory." Felix whispered, "It's very difficult. Therefore, it's very precious." Dumbledore was

a little relieved, "It seems that you have really gained a lot in the past few years." Then he suddenly asked a question, "Then why are you so persistent in coming to Hogwarts to teach?"
