For the textbook of the magic technology class, Rhine has carefully considered and intends to divide the theory of the magic gun into three parts.

The first part is the basic theory, as well as the definition and principle of magic weapons, and of course, simple incantations.

The second part is to learn spells and more spells, and in this part you can make magic bullets independently.

The third part is all the rest of the knowledge, which can be learned to make a complete magic gun.

For the next two days, Rheinland spent most of his time writing textbooks and practicing flyboarding whenever he had free time.

Busy time flies, and in the blink of an eye, it is August 30th, and there are still two days before Hogwarts starts on September 1st.

It's time to report to Hogwarts.

Taking advantage of the teacher's privilege, Rhine directly carried a suitcase and flew powder in his hand, standing in the fireplace.

"Gryffindor House Lounge!"

After shouting the name of the destination, Floo Pink raised a blue flame, and Rhine's figure disappeared with it.

By the time the blue flames in front of him dispersed, Rhine had already appeared in another environment.

This place is very familiar to the Rhine, it is the common room of Hufflepuff House, where Rhine lived for almost seven years.

At this time, the school had not yet opened, so there was no one in the lounge.

It was already a bit cool at the end of August, the fireplace was not lit and the lounge was somewhat shady.

I don't know who put a book on the table, Rhine picked it up casually, and saw that the cover read "I Can Magic", written by Gilderoy Lockhart.

"Bang."

Rhine hurriedly threw it back.

The dormitory was fairly clean, with no rubbish other than the thief's book.

There was no dust on the furniture, it must have been cleaned recently by a house-elf or Filch.

Rhine walked out of the lounge and walked down the ever-changing staircase, following his familiarity with the Gryffindor Tower.

After stepping out of the tower, Rhein took the flyboard out of his suitcase, sat on it, and began to revisit the campus.

Passing through the castle arch, Hagrid's cottage is in the distance on the left, and the Forbidden Forest in the back. There is a small river on the right, and on the other side of the river is the Quidditch pitch.

Sitting on a flyboard and holding his suitcase, Rhein floated through the middle of the air across the river, through the small doors of the court, to the center of the court.

And at this moment, an old and deep voice sounded next to itself.

"It's a place where you have memories of when you were very good at finding balls. Mr. Embers, remember what you told me about when you first came to Hogwarts? ”

Rhine stopped the flyboard, heard the sound, and the gray-haired old figure in his memory reappeared in front of him.

He quickly jumped off the flyboard and removed the top hat from his head.

"Headmaster Dumbledore, I'm sorry I didn't report to you at the Headmaster's Office in the first place, I miss this place so much, so I thought I'd come over and have a look first."

Dumbledore still had that serious look, which was very similar to Professor McGonagall.

Instead of blaming Rhine, he continued: "Then you told me that your dream was to become the greatest wizard. ”

Dumbledore turned his gaze to the flying machine floating in mid-air beside Rhine, and said, "Now it seems that this dream is coming true little by little. ”

Rhine is still a little afraid of this principal, after all, there is something in his mind that cannot be revealed, in case he is taken by the dementor, it will be cold.

Just now, Rhine didn't go to the principal's office for the first time, and he also wanted to think about how to deal with it.

After thinking about it for a long time, there is only one way - if it really doesn't work, just think about the spell theory, after all, I am studying this now.

Dumbledore's eyes seemed to be bottomless, he looked at Rhine, and said, "Your intention to come to Hogwarts to open a new subject was written down by me and submitted to the school board, and their response to me was to put you into the job immediately, and prepare everything for you. ”

Rhine frowned, always feeling that Dumbledore meant something else.

As if he wanted to see through Rhine, Dumbledore asked with straight eyes, "Rhine, what is the purpose of your coming to Hogwarts?" Wouldn't it be more comfortable to make a living selling your new invention in Tumbledown Alley? ”

Rhine could sense that Dumbledore was doubting himself.

Since the school board is mentioned, it means that the attitude of the school board is problematic, a little too positive, and it is difficult not to wonder what Rhine has to do with the school board.

But Rhein does not have a backstage of the school board, and the only thing he has to do is also a grudge against Lucius.

Since Dumbledore's question was this, Rhine had a clear conscience, so he simply didn't shy away from it.

He laughed, and there was a hint of bitterness in his smile: "Headmaster, to tell you the truth, my father has a grudge against Lucius, and these grudges have been transferred to me with the death of my father. ”

"I didn't just come to Hogwarts to delve deeper into magical technology, I also wanted to make the home I've lived in for seven years a safe haven."

"As for the school board, professor, I really don't know why, I was stunned for a long time when I received your letter."

As he said these words, Rhine clearly felt a strange feeling in his head.

He understood what that meant, but now he was telling the truth, and he wasn't afraid to be seen through what he really thought.

Dumbledore didn't want to use a deeper dementorship on himself, he forced himself to remember, to be honest, there was no need.

The strange feeling quickly disappeared, and Rhine only frowned, and restrained the other manifestations well.

Dumbleder smiled insightfully and handed the Bibi Bean in his hand to Rhine: "I remember that I reminded you in the letter to prepare the textbooks, give me the new textbooks, and Hogwarts will help you make them more numerous and more refined in appearance." ”

Rhein knew that he had passed the test.

So he used the magic gun in his hand to shoot the suitcase on the flyboard, and took out the three notebooks in the air.

"That's what I've prepared, Headmaster Dumbledore."

Dumbledore beckoned, and the three notebooks flew into the big old hands.

He looked at it for a while, nodded his head again and again, and after a while, he looked up at the flying board floating in the air.

"What an amazing idea, Mr. Embers. Is this flying thing also a type of magic weapon? ”

Rhine nodded and said, "This is a new invention that I have been researching for a long time, and of course, the assistance of Miss Granger and Mr. Potter is indispensable. ”

Dumbledore looked at the flyboard carefully.

Obviously, he was very knowledgeable about Hermione and Harry's recent movements, so he didn't ask too much.

After a while, Dumbledore looked away from his flyboard and said to Rhine, "Your father will be proud of you, Mr. Embers, and I am sure that you will become a great wizard in the future." ”

"Thank you for your affirmation, Headmaster Dumbledore." Rhine said modestly.

Dumbledore turned, and as he walked out of the court, a voice could be heard behind him.

"Go find Professor McGonagall, she'll help you get everything ready."

Rhine finally breathed a sigh of relief, and then sat back on the floating flyboard.
