"Is Hagrid alright? I underestimated the damn weather. I felt like I was freezing. Looking at the tree cutting in front of him, Haige Yang asked out loud.

At this time, Hagrid, who was constantly wielding the axe in his hand, slashed out the last blow with all his might. As the tree fell, Hagrid looked at Yang Su and said, "Okay, then take this tree back." After 11 more trips, you will be able to complete the task of 12 Christmas trees. ”

"I really don't know who paid attention," Yang Su said helplessly as he heard Hagrid's words, and instead of getting twelve similar Christmas trees, it was better to cut down the largest and tallest one as decoration.

"That's not going to work." Listening to Yang Su's words, Hagrid immediately retorted, "It's not easy for those trees to grow so tall. It may take decades to grow. It's not like these few trees, and after three or four years, a whole bunch of the same trees will appear. ”

"Alright, hurry up. I'll send us back with dimensional magic. Helping you deliver a Christmas tree is also my contribution to decorating the hall. ”

As Yang Su's words fell, Yang Su used his magic power to cause a crack to appear at the feet of Hagrid and the big tree. A few minutes later, the two of them appeared in the halls of Hogwarts.

Hagrid felt a little dizzy, and after placing the tree he had just seen in the designed position, Professor Flitwick and Professor McGonagall unleashed their magic and began to decorate the Christmas tree.

Then Yang Su opened a dimensional passage outside the door of the hall. In a matter of seconds, you will be able to reach the Forbidden Forest where Hagrid has just cut down the tree. After continuously releasing magic to consolidate the passage, Yang Su opened his mouth and said, "Okay, Hagrid, you can go directly. After cutting down the tree, you can come back from this tunnel. To be honest, I'm not really well suited to the cold weather outside. ”

If it was cold outside because of the ice element, it was good that Yang Su could use this to enhance the power of the Ice Freezer profession, but this was actually pure cold. Standing in this cold weather, the improvement of the ice master profession can be said to be minimal.

Although Yang Su may have the opportunity to comprehend the true meaning of cold in cold weather, in this world, the elements have long been sealed. Even if you realize it, it won't do anything for the time being. Yang Su was not interested in anything that was greater than the gain.

Although it takes a lot of magic to consolidate this dimensional channel, even if Yang Su's magic power is pitifully small now, he can still open this small dimensional channel for a whole morning. Of course, this must be done when the passage is open and no one destroys it.

Hagrid returns to Hogwarts with one Christmas tree after another. Flitwick and Professor McGonagall decorate the hall together. At this time, the auditorium is beautiful and magnificent. The walls are covered with weeping ribbons of holly and mistletoe, and twelve Christmas trees are erected in the hall, some with shiny Xiaoice pillars, others with hundreds of candles.

"It's finally done," Yang Su couldn't help but sigh as he looked at the beautiful hall after the decoration. Hagrid said, "Thank you." Without that dimensional passage, I'm afraid I'd have to work all morning to bring these trees back. ”

"It's nothing, it's not very difficult to open the dimensional passage, it's just that it takes more magic." Listening to Hagrid's words, Yang Su smiled and said, "If it's okay, I'll go to the library." It's still a while before lunchtime. ”

With that, Yang Su turned around and left the hall.

"It seems that Robin's consumption is very large, in the past, he used to directly open the dimensional crack and pass through." Looking at the figure Yang Su leaving, Hagrid's mouth muttered.

……

"Hey! Hello Mrs. Pince. Is Schrödinger Jr. okay? At this time, Yang Su, who walked to the library, looked at the librarian in front of him and said hello.

Yang Su and Schrödinger, who were in the forbidden area of the library every day, naturally became familiar with the librarian. In addition, Yang Su often directly opened the dimensional crack and left, and then Schrödinger forgot about it in the library. Schrödinger, who didn't know much about the terrain of the academy, didn't plan to go out to find him. When Yang Su left, he would run to Mrs. Pins to find a place to sleep.

"Professor Robin, you were so careless. You said this is the first time this month. Leave Schrödinger here every time, whether it's my pet or yours. For Yang Su, Mrs. Pins at this time can be said to be deeply resentful.

"Haha~" Listening to Mrs. Pinsi's words, Yang Su pretended to smile stupidly and said, "I'm sorry, I'm sorry, I'll pay attention next time." ”

After speaking, he took Schrödinger to the forbidden book area. Picking up a book casually, Yang Su found a place to sit down and read it.

Time passed quickly, and when there were still ten minutes before dinner started, Yang Su put away the books. As he was about to leave with Schrödinger, a figure walked into the forbidden section.

"I remember that books here had to be read with a note from a teacher or Dumbledore's permission. Can Harry tell me what you're doing here? ”

Looking at the little guy in front of him, Yang Su asked with a smile.

That's right, it was Harry who appeared in front of Yang Su who was looking for Nicolmel's traces in the library. He was in a dizzy way in the library. When he saw Yang Su, he was startled: "Professor Robin, why are you here?" ”

"Haha~" Listening to Harry's question, Yang Su smiled and said, "It seems that you don't come here very often, Harry." I often come here to find some books to read. I know all the books in the forbidden area. ”

"Really?" Listening to Yang Su's words, Harry looked a little excited and asked, "Then do you know Nicol Meller?" In the forbidden book area, have you seen his account? ”

Yang Su didn't expect Harry to ask him such a direct question. Although he knew about Nicolmeler's situation, Yang Su did not intend to break it directly. After thinking for a while, he said, "I'm sorry, but most of the books in the forbidden section are very old, and there is no mention of Nicolmel in them. But I've heard Headmaster Dumbledore say that Nicolmeler is his friend. You might want to ask the principal. ”

"That's right." Listening to Yang Su's words, Harry looked a little lost. After all, he managed to get the name Nicolmeler from Hagrid. It's almost impossible to get the message you want from the principal in the same way.

Seeing Harry's disappointed departure, Yang Su smiled and reminded, "You can look up the books about Dumbledore, maybe there will be records, maybe, right?" ”

"Why didn't I think of this," Harry patted his head at Yang Su's words, and his emotions seemed very excited. Hurriedly thanked Yang Su: "Thank you very much." ”

"Nothing. But I'd like to remind you that it's almost time for lunch. Instead of checking the information, let's go to dinner first. ”
