"I'm sorry," looked at Yang Su, who was Dumbledore in front of him, and after apologizing softly, he stepped forward and reached out to help.

Teleported with the Headmaster to the Infirmary, and after Dumbledore was treated, the two teleported back to the Headmaster's office together.

"Since you are willing to pay for nothing, then I agree that you will become the new subject professor at Hogwarts. But there is one thing, I want you to be able to compile a textbook for the Dimension Studies course and so on. You don't want your students to not even have a book to refer to. ”

Sitting in his chair, Dumbledore had already agreed with Yang Su in front of him, but even though Yang Su showed amazing strength, Dumbledore still said what he wanted. After all, the lesson Yang Su was going to teach was magic that no one had ever used before.

Thanks to Robin? Hyles is a professor of Dimensionalism in the Magical Society. Although the number of people in each class can be counted with the palm of one hand, he is a professor anyway. The teaching book system is passed on to one's own memory.

"This one is very simple, and I will write it as soon as possible. I would also like you to help me publish these books. After all, I also want this magic to spread in this world. ”

"Yes, understood. Your dormitory is in a secret room next to me. Hogwarts ancestors often carved out their own rooms in the school. These discovered chambers also served as dormitories for many professors in the future. Also, you should have enough money to buy a wand, even though you don't seem to need it for your magic. But I don't want your identity to be discovered that you don't belong in this world. ”

"I'd love to do it, but there's something I have to tell you." Listening to Dumbledore's words, Yang Su said embarrassedly, "I don't have money on me, and anything of value. Traveling through the world has caused everything I had before to dissipate, even the clothes on my body have been kept in a state where they can be seen using transfiguration. ”

"What a poor fellow, by the way, the teacher's wizard robes are still distributed for free. There is no set pattern for the school, and you can ask for anything. As for the money to buy a wand, I'll have it when your textbook is published. I'll give you a discount that I've agreed with Ollivanders. As long as you go buy it before school starts. Listening to Yang Su's words, Dumbledore seemed to be holding back his snicker: "By the way, if you are hungry, you can go to the hall to eat, I can just introduce the professor of your new course to the senior students who stayed at school to review during the summer vacation." ”

"Good principal. I'll give you the design book of the wizard's robe at dinner. ”

Although Yang Su no longer needs to eat to get the energy of life. Tastes have long since changed. However, it seems that with the seal of the blood mage profession, his sense of taste has recovered. It's also good to go and eat. I hope you don't see stargazing at the stars at dinner at Hogwarts.

After breaking through the dimensional shuttle and arriving at his dormitory, Yang Su started his own cleaning, as if it was because of the passivity of the dimensional mage, Yang Su also had a serious cleanliness habit at this time. After the light magic illuminated the entire room, Yang Su found an ordinary broom and began to clean himself. It took a long time to clean up this dusty secret room.

"What kind of clothes should I choose," Yang Su believed that if he chose to look like a magician in the game, he would definitely kick Dumbledore out. Although it looks quite handsome, from the eyes of these old people, it will definitely teach bad children.

A slightly decorated black shirt and pants, plus a wizard's cloak and wizard hat, Yang Su completed his design. Looking at his future clothes on the paper, Yang Su nodded with satisfaction: "Simple and handsome, I am really a genius." ”

In a blink of an eye, time passed quickly, and it was almost time for dinner after Yang Su's cleaning and clothing design were resolved.

Scratching open a dimensional door, Yang Su came to the hall of Hogwarts when he passed through.

"Well, here we are." Looking at Yang Su in front of him, Dumbledore smiled and introduced the person who suddenly appeared in the hall to everyone: "This is the professor of the school's new curriculum, Mr. Robin Huloes. He will teach you a new lesson in magic. Since this subject can be too difficult, I have listed it as an elective. (PS: I changed the previous chapter, and Yang Su used the name Robin Hulos in this world.) ）

Looking at the few senior students in front of him, Yang Su smiled and said, "It's a pleasure to meet you, and I hope that someone will be willing to take my class next semester." However, as the principal said, my course is too difficult, so students who are taking the General Wizard Rank Exam (O.W.Ls) and the Ultimate Wizard Rank Exam (N.E.W.Ts) should do what they can. I don't want people to be denied graduation because of my course. ”

"Robin, I don't want your classes to be banned because no one is taking them." Listening to Yang Su's actions as if pushing people out, Dumbledore said with a smile.

"Don't worry, although this magic is a bit difficult, I will make the students feel the charm of it. I don't think I'm going to be banned. As soon as Yang Su's words fell, he sat down in the position of the mentor and ate the food teleported by magic on the plate. ”

"Okay, I don't know much about the new discipline of dimensionals. But there's no denying that it's a powerful and systematic form of magic. I hope that students who have the ability can learn. Textbooks for this subject will be released before the start of the semester. With that, Dumbledore sat down and began to eat dinner.

In the hall, the senior wizards present with Yang Su, the new professor, began to discuss this new subject.

A student from a snake academy: "Dimensionality? Haven't heard of it. And the name of the mentor has never been heard of? It's time for the elders in the family to go back and check on the new professor. ”

A student at the Lion Academy: "Dimensionalism is very interesting, and the new professor looks very interesting, I hope he won't be as strange as Professor Sybil Trelawney in divination." ”

A badger college student: "It's better to concentrate on the exam." It seems difficult to listen to the professor about the new subject. ”

A student of the Eagle Academy: "This is not only a new discipline, but also a new magic, and I have never heard of the magic of the dimensional system in the history of the past. ”

……

Not caring about the students' communication, Yang Su left the hall together after lunch with Dumbledore.

In Dumbledore's office, Yang handed Dumbledore his own design for his wizarding robes.

"I thought your clothes would be special. I didn't expect it to be pretty good. Looking at the design that Yang Su had given him, Dumbledore said with a smile.

"If you agree, I can switch back to the original design." Saying that, Yang Su used the transformation technique on the design drawing.
