Hogwarts I have been guarding Azkaban for ten years

Browder agreed to Hermione's request and decided to let Hermione come to him when she had time.

"But are you really sure about this?" Browder asked.

"In the end, the people participating in the competition are all students with the best grades this semester. We haven't finished the exam yet, are you starting to worry about not being able to compare with them?"

Ron took a step forward and said very firmly: "Hermione is now the student with the best academic performance. I believe she can do it!"

Hermione glanced at Ron with some emotion. It was the best thing to have a friend who always supported her.

Harry also knew that there was nothing wrong with Hermione.

"Uncle Browder, Hermione is studying very diligently, and I think there is nothing wrong with Hermione."

Browder laughed dumbly: "Okay, okay, since you all feel this way, then let's prepare like this first."

Hermione raised her little head: "Professor Browder, I think even if I am not No. 1 in the final exam, I still have a very good chance of getting No. 1. I start preparing now just in case I need it."

Browder felt that what Hermione said was very reasonable, and he also felt that there were not many students who were as willing to study as Hermione. Currently, he was only Cedric, who could be considered a hard worker, while the Weasley twins were pure practical giants. Theoretical dwarf.

Although the Weasley twins are currently the most efficient in applying Browder's research, Browder still needs students like Hermione and Cedric if he wants to spread the contents of his research into books.

Harry and Ron walked away happily, sincerely happy for their good friends.

"Sit down," Browder looked at the rather stubborn little girl in front of him and gestured for him to sit on the chair. "I don't know what kind of content you want to learn. I'm not exaggerating. Generally speaking, I know everything. I know a little bit about it, but I’m not particularly proficient.”

After being modest, Browder added in his mind: Compared with those three people, he is not particularly proficient.

Hermione was sitting on a high chair, her legs dangling in the air, shaking her feet constantly.

"I don't know what to study. I think it should be something that can help me pass the final test between the two schools."

Hermione said, looking at Browder with hopeful eyes, hoping that the professor could reveal something about the competition to her.

But it's a pity that Browder is not like Hagrid, who likes to talk about important secrets casually.

Browder just looked at Hermione and smiled until Hermione felt a little embarrassed.

"Okay, okay, I want to learn the magic about visual illusions first. This should help me a little." Hermione finally surrendered under Browder's eyes.

This is not beyond Browder's expectation. Browder is now most famous for his visual illusion magic, and his adaptability is also very strong. If he can use it at a similar level as Browder, even in the wizarding world, he can Walked sideways.

Browder did not force Hermione to choose a path. It was the students' own choice to take whatever path they wanted to take.

"If you want to learn optical illusion magic, then we must first understand what light is and how our eyes see things."

Browder patiently explained simple junior high school physics knowledge to Hermione.

After talking for a while, Browder suddenly had a feeling that the separation between students in the wizarding world and the Muggle world was really too great.

Some of the most basic common sense of life are unheard of in the wizarding world.

Browder used to think these things were a bit funny when he was watching the movie, but now that he thinks about it, he really feels that these things are a bit scary to think about.

If this development continues, the Muggle world's technology will become more and more advanced in the future. Even if a genius like Dumbledore appears in the wizarding world, won't there be any way to reverse the entire battle?

This would make Browder feel very sorry.

Because the magical ability of wizards is actually very useful to all human beings.

If the two sides kill each other and one of the races disappears, it will be a very regrettable thing for the entire human race.

Who will deal with the Trisolarans then?

Browder thought wildly.

"I understand! In fact, the visual magic taught by you is to use the principle that human eyes need to use the element of light to see things. As long as we can control the light seen by the opponent, we can control what the opponent sees."

Hermione was a very smart student and quickly understood the meaning of Browder's illusion magic.

After all, the principle of Browder's illusion magic is not very difficult to understand.

The difficulty is not here. The key difficulty is how to control these lights.

Most people know the principles of nuclear bombs, but who can build a qualified nuclear bomb?

"That's right, so if you want to learn this illusion magic, you need a lot of practice. Only when you are familiar with this magic can you use it in battle."

Browder said, crossing his hands across the table, a phoenix with its body burning with flames appeared on the table.

"Oh hoo!"

Hermione was startled, then thought that Browder was showing her an illusion, and then she calmed down a little.

"You see, this is illusion magic. Now I can complete illusions that look real and fake without the help of thick fog."

Browder said with some pride: "But you can't. There are actually many tiny particles in the dense fog. These things can help us quickly reflect and refract the light we need."

Hermione watched the illusory phoenix created by Browder flying around her, and was surprised and admired the magic of Professor Browder.

"Here are books for learning optical magic. You need to understand the contents first, so that you can have a better understanding when creating illusions."

Browder handed Hermione the junior high school optical knowledge he had compiled.

Hermione thanked her, stretched out her hand to tie it, and flipped through it, finding that it basically talked about the movement of light in the air.

There is also how light moves in media of different properties, from air to liquid, from liquid to solid, and what changes occur therein.

It's all that, not much magic-related stuff.

It seems that Professor Browder wants me to lay the foundation first, master these things first, and then start practicing after a little study.

Looking at Hermione's leaving figure, Browder felt something wasn't right.

Hermione is only a first-year student now. I am giving her lessons in advance. Does this count as involution?
