A day at Hogwarts.

Chapter 376 Why don’t you transfer here?
Charles was very curious about Kodosdorez's teaching. Now that he had Elizabeth and the others as translators, he no longer had to be a translator and could audit the courses.

The classroom for the magic item making class is on the top floor of the main castle. Students who take this class are all in grades 6 and 7. They need to complete and pass the prerequisite courses in grades 1 to 5 before they can choose this course.

Charles decided to sit in on the class, and after breakfast, Dumbledore took time out in the corridor to tell him not to cause trouble, especially not to mention Grindelwald.

As soon as he gave the instructions, Professor Chepkin, who taught this course, took the initiative to find Charles.

"Are you Smith?" Professor Chepkin seemed a little familiar. "I'm glad you can come to my class."

Charles politely replied, "Hello, Professor Chepkin. It's a pleasure to learn from you."

Professor Chepkin waved his hand and said, "Don't be so polite. Let's all call you by your name."

Here, there are some differences in the details when using "你" (Ты) and "你" (Вы). "你" is used by subordinates to superiors, juniors to elders, and as a respectful title, and is relatively cold, while "你" is used among friends and peers, and appears to be more intimate.

Professor Chepkin said to Charles enthusiastically, "Why don't you transfer here? We are very interested in your research."

Dumbledore was very unhappy with this poaching behavior in front of him and couldn't help coughing twice.

Professor Chepkin pretended not to hear him and said to Charles seriously, "Mikhail and I have discussed that your ideas on alchemy are very innovative. Once successful, they will change the world. If you are willing to come to Kodosdoriz, we will fully support your research."

Charles' heart skipped a beat.

Professor Chepkin continued in a low voice, “There are two comrades who are also interested in your research and they speak very highly of it.”

Charles asked curiously, "Who is it?"

Professor Chepkin simply replied: "They want to see you, and they will arrange it."

After he finished speaking, he patted Charles on the back and said, "I have to go to the classroom first. If you don't pay attention later, hey, I will ask you to give Bai a bath."

Charles watched Professor Chepkin's back disappear into the crowd in the corridor, thinking deeply, always feeling that there was some huge secret hidden here.

Dumbledore looked at Charles and thought that he would not turn back, after all, his property was right next to Hogwarts.

Charles didn't notice Dumbledore's reaction and continued to think as he walked.

He had previously written to ask Valentina whether alchemy had conducted any research on metal resistance. Unexpectedly, the professors had keenly discovered what he was trying to do. Perhaps there were some discrepancies in the details, but the general direction should be correct.

"Charles!" Harry tapped him on the shoulder from behind. "What class are you going to?"

Charles replied, "Magic item creation, what about you?"

He spotted Harry and his trio with Seamus, apparently going to the same place.

Harry said, "Neville went to the Herb Planting Class. Let's go to the Charms Combat Class. I wanted to ask you to go with me last night, but your room door was locked."

Charles made an excuse about what happened last night: "We were in a meeting last night."

Seamus said in disbelief, "I think it's with the girl. Ruby even ran to my room."

Charles nodded immediately: "Ah yes, yes, with four girls."

Seamus shook his head and said, "That's bullshit."

As they were talking, they separated and the classrooms went in different directions.

Charles came to the classroom and sat down in the last row, with many guests next to him. He saw Louis Manz and Kitov sitting together in the first row, and after thinking about it, he decided to sit in the last row.

"Hello, Mr. Smith."

Sitting next to Charles was a boy from the Japanese Magic Institute, wearing a light golden haori, which showed that he was quite knowledgeable.

Charles chatted with him for a while and found out that Honda Mihide was a neighbor of his pen pal Yamada Hakumitsu. The two often went to and from school together. The snacks that Yamada Hakumitsu often gave him, such as the lively taiyaki, were bought from his family's snack shop.

Before the two could talk any more, Professor Chepkin came into the classroom, followed by a young polar bear carrying a bunch of broomsticks.

The class started and the room suddenly became quiet.

Professor Chepkin picked up the list and said seriously, "Students who are not here, please raise your hands."

The students of Kodos Dorez were used to it, and several of the guests laughed out loud.

Professor Chepkin threw the list into the air, and the list folded itself into a paper airplane and flew to the podium.

He began, "As you all know, yesterday the students from the Budyonny Club flew the No. 25 broomstick to a speed close to Mach 1.1, once again saving the school's roof."

"I later checked all the brooms and found that every single one had different types and degrees of damage to the broom branches."

"That's exactly what I'm going to be talking about in class today, and I'm going to use these brooms as an example."

He waved his wand and a metal broom flew in front of him, floating in the air.

Then with a flick of his wand, a huge projection of the broom appeared above his head, allowing the students to see where the problem was.

Charles noticed that the metal broomstick had many wrinkles perpendicular to the central axis near the fixed position, which should be caused by metal fatigue.

Professor Chepkin waved his wand again, causing the broomsticks to spread out, and the areas where the problems occurred were circled by blue circles of light.

He told the students: "When the broom is flying, the tail branch will suffer from metal fatigue and damage due to long-term and intense vibration. If it is not treated and continues to be used, it will break."

"Yesterday afternoon, a classmate told me that this didn't happen with wooden brooms before. This classmate is wrong. Wood also has material fatigue. This is because wood is relatively tough and can absorb some energy during severe vibrations. Moreover, the fatigued areas do not look obvious."

"There are many ways to deal with this problem. The best way is to change the design to avoid vibration as much as possible. The most passive way is to strengthen the location where fatigue occurs."

"Next, I will talk about how to strengthen metal parts without changing the design, or when you don't know how to change the design."

"There are two main ways to strengthen it. The most commonly used one is to use alchemy and strengthening spells to strengthen the properties of the material, making it more durable."

"Sometimes alchemy and strengthening spells will conflict with the spells on the parts, so another method is used to strengthen the structure. The first type of strengthening can be performed on the reinforced structure, while avoiding interference from the spells."

"Yesterday, the core module of the Space Club was not properly protected from interference. When the heating spell was activated, it affected the spell controlling the attitude."

"This effect accumulates gradually. The control spells become less and less effective, and finally become completely ineffective."

"Students who have prepared for the textbook already know that next month we will teach you how to prevent interference with spells in complex spell environments. This is the focus of this course, so please prepare well."

Professor Chepkin first gave an outline of today's lecture, and then began to talk about the details.

Charles listened carefully and soon had a familiar feeling, as if he had discussed issues related to magic machinery with others somewhere before.
