After singing the school song, the prefects of each college returned to the dormitory with the students of their respective colleges, and Yang Su also walked into his staff dormitory to rest.

……

Yang Su got up from bed early the next morning, and after brushing his teeth and washing his face, he found a grass area and set up chairs and tables. The house-elves who communicated to Dumbledore asked them to bring their breakfast.

Soon, a flash of crystal light flashed and saucers and cups appeared on the table, followed by a sandwich and a glass of milk.

Eating his breakfast, a hole appeared out of thin air next to Yang Su. A graceful figure slowly stretched out from within.

"Neyali, what's the matter?" Looking at the beautiful succubus in front of him, Yang Su put down the half-eaten sandwich and asked.

"Come and see you, dear master." Listening to Yang Su's words, Nayali smiled charmingly and said lightly: "I really don't understand why you want to stay here, I see that you have nothing to do every day." ”

"Nothing, just complete the task." Listening to Neyali's question, Yang Su smiled and said, "What about you?" Is there anything to do with me? ”

"It's not important, it's just that I haven't seen you for too long. Come and have a look. ”

Listening to Neyali's words, Yang Su asked with a smile, "You are quite idle." It's about the same time, and I'm going to class after breakfast. I can't be late for the first class, as a teacher. ”

"Good luck then. This world is so low-level that I don't have any interest in it. Get out of here as quickly as you can. I want to go to other worlds with you. ”

"Then you may have to wait for a few years, after all, my strength has not fully recovered, and I can only stay here as an ordinary teacher for the time being."

"Goodbye to the ordinary magic teacher, then."

As she spoke, a magic circle appeared under Neyali's feet, and she saw Neyali's figure slowly enter the circle and disappear without a trace.

……

After eating the remaining sandwich in his hand and the milk in the cup, Yang Su put the chair back. Walking slowly towards his classroom, Yang Su could clearly see that several little wizards were running quickly towards the breakfast restaurant. Dumbledore can be said to be very preferential to the students who took Yang Su's course. As long as they pass Yang Su's exam, no matter how they fail other subjects, they can get a graduation certificate.

The main thing is that dimensional magic is powerful and profound enough, if the dimensional magic taught by Yang Su is only one move, Dumbledore will not let Yang Su open a class here.

Walking into the classroom, the students who had taken Yang Su's course had not yet arrived, but Yang Su planned to do a small experiment to see if these students had previewed the dimensional books they had written in advance.

Although self-study in preparation does not allow them to learn to use dimensional magic, it can make it more convenient for Yang Su to teach. For example, when you say what you want to talk about, students who have pre-studied will know exactly what they are going to learn on that page.

Wielding a wand made from Neyali's hair mixed with elderwood, he got from Ollivanders. To be honest, Yang Su didn't feel any difference between different woods. But this wand, which was mixed in with Neyali's hair, was indeed surprisingly easy for Yang Su to use.

Waving the wand in his hand, Yang Su opened a spatial gap above the door of the classroom. Use some magic tricks to cover up the crack. As soon as the little one who opens the classroom door and walks into the room is not careful, there will be flour or water and something like it on the top of his head. Considering the difficulty of cracking, Yang Su controlled the magic so that the students could easily sense that there was something wrong with the space above their heads.

"Unfortunately, the first student didn't notice anything strange overhead, but he was fast enough that he seemed to be sprinting so fast that he dodged the flour."

"Whew, whew. ~" The third-grade wizard who ran close to the teacher seemed to be tired of running, and asked breathlessly, "Teacher, I, I'm not late." ”

The little wizard in front of him is called Berry, who is from Ravenclaw, and he is from an ordinary family, and he has loved all kinds of reading since he was a child. His father was a knowledgeable ordinary man who worked in a library.

When he entered Hogwarts, his father thought it was an invitation from a liar.

After all, the location of Diagon Alley and the location of Platform 9 are too strange.

Looking at the anxious expression of the little wizard in front of him, Yang Su smiled and said, "You didn't arrive late, but arrived 10 minutes early." Let's wait for the next classmates. ”

As he spoke, Yang Su restored the design just now, and invited Berry, who was lucky enough to escape, to see how the next few students would respond.

At this time, Berry was happy that he had passed Yang Su's prank in a daze. At this time, a little girl was slowly walking to the front of the classroom. Unlike Berry, she comes from Gryffindor. As she was about to enter the trap, she picked up her staff and cast a spell on the gate in front of her, saying, "Alaho Cave opens." ”

The classroom door was opened, and I watched Berry sitting in front of me and Yang Su, a little girl from Gryffindor, walking into the classroom.

"Ah~"

But as soon as she reached the door, she heard a scream. The sudden fall of flour from the sky made it impossible for her to dodge.

Ready for pranks, Yang Su is certainly ready to deal with these pranks. In the past two months at Hogwarts, Yang Su has not been in vain, and Yang Su has mastered a lot of life magic in the books. This effortless magic doesn't have to be in vain.

"Clean and new." As the flour on the girl's whole body was cleaned up, Yang Su smiled and said, "Hannah, your vigilance is very high, but you are also easy to let your guard down. If you just open the door and run to the classroom or uncover the magic that has been placed in the doorway, you will be able to escape. ”

"Alright, find a seat and let's see how the last student performs."

As soon as Yang Su's words fell, this little snake from Slytherin walked into the classroom before Yang Su set up the scene. "Teacher, I've come in."

"Well, you're in luck." Looking at the three students in front of him, Yang Su said with a smile: "Although my course has the smallest number of electives, it can definitely be called the most difficult to learn. Except, of course, the science of divination, which is all talent and seems to be of no use. I hope that you will seriously study and feel the power of the dimension. Now, I'm here to teach you how to condense the Dimension Stone. and perform simple and ordinary dimensional magic attacks. ”

First of all, you need to concentrate your mind on the power of space. Pay attention and you will see the nodes of space, which are the subtle connections to the other world.
