Hogwarts Passer-By Professor

As for why Eisen put his idea on the tape recorder, it actually originated from a previous idea. That is to transform the tape recorder through alchemy and magic, turning it into a magical prop that can record sound.

In doing so, it can register the deadly call of mandella. In this way, Eisen might be able to acquire a fatal attack characteristic.

The next day, Eisen continued to be busy with his own affairs in the office. In fact, apart from still borrowing some alchemy books from the library to study and study, he is still practicing Occlumency.

Perhaps because of Eisen's hard work in Taoism, he really found a little trick, and finally he can achieve the state of initially emptying his mind and thinking about nothing.

In this state, Eisen can control his emotions so that outsiders cannot judge his thoughts through his expressions. Of course, it also has a certain resistance to spiritual penetration magic such as Legilimency.

However, Eisen was not very skilled in entering the state of Occlumency. If you want to hide your thoughts from Master Legilimency, you need to continue to work hard.

As for fabricating a memory in one's own mind, that is a more advanced skill.

However, after studying alchemy in depth, Eisen discovered a problem. That is, his knowledge is somewhat insufficient. At the beginning, when he learned some relatively simple knowledge of alchemy, he didn't notice anything. But after going deeper, it was discovered that alchemy also involved the knowledge of ancient runes and potions.

On the one hand, a lot of advanced alchemy knowledge is recorded in ancient runes, or at least some key points are recorded in ancient runes. On the other hand, some difficult alchemy skills also need specific potions to assist.

If Eisen is just a beginner and doesn't plan to study in depth, then he doesn't need to learn ancient runes and potions, but if he wants to go deeper, he must master ancient runes and potions to a certain extent.

Dongdong——

A sudden knock on the door interrupted Eisen's thoughts.

"Come in!" Eisen opened the door with a wave of his hand while speaking. I also felt strange in my heart, when my office was so busy, people came over one after another.

"Professor Eisen—" a petite figure rushed in, and then quickly closed the door. When she saw the surprised expression on the face of Professor Eisen sitting behind the desk, her face suddenly turned red.

"Hermione, are you here for something?" According to Eisen's understanding, the trio should have known what was under the trapdoor recently. However, Hermione came to his office with a sneaky expression, which made Eisen more curious.

[In other words, currently the best app for reading and listening to books, Yeguo Reading, yeguoyuedu install the latest version. 】

"Yes, Professor Eisen—" Hermione's little head nodded, thinking about what to say.

"Relax, don't be too nervous. Sit down, please!" Eisen smiled, and at the same time, with a wave of his hand, he threw a card into a chair and placed it in front of Hermione.

"Thank you, Professor Eisen, this is your Christmas present!" Perhaps infected by Eisen's smile, Hermione heaved a sigh of relief, then took out a long box and placed it in front of Eisen, then sat down down.

"Christmas gift?" Eisen froze for a moment, he had given Hermione, Harry and Ron a storage ring respectively, but he did not expect to receive a Christmas present.

However, it seems that Christmas is already over. Time for Christmas presents? There was a look of doubt in Eisen's eyes, and then he glanced at Hermione's finger, yes, the ring he gave was worn by Hermione on the middle finger of her right hand.

"Yes, Professor Eisen, I don't know your home address, that's why I sent it here now, I hope you won't be offended." After noticing Eisen's eyes, Hermione felt a little embarrassed again. However, she still explained why Christmas had passed and why she came to give Christmas presents.

"Oh, how could it be? I have to thank you for remembering to give me a Christmas present." Although it was a late Christmas present, Eisen would not blame the other party anyway. He stretched out his hand and opened the box. Quilling a quill, "Whoa, I just need a quill to write a script? Thank you, Hermione!"

Well, Eisen does need a quill, because he just happens to be taking some time off to write some scripts to send to his dad. However, he still plans to see if Fred and George have invented an automatic writing quill in a while, and then buy one for use. Unexpectedly, Hermione sent a quill.

"Writing a script?" Hermione felt that she had misheard, and suddenly opened her small mouth and looked at Eisen in surprise.

"That's right, um, you may not believe it, I actually have a Muggle film and television company in London, so I will find time to write some scripts and send them to the company." Eisen looked at Hermione with a smile on his face, revealing a faint complacency look.

However, when it came to this point, Eisen had a whim, whether to directly write the story of Harry Potter into a script and make it into a movie. In other words, if you are worried about getting Voldemort's attention, you can change the perspective and make a movie with Hermione as the protagonist.

Of course, due to the law of secrecy in the wizarding world, Eisen's idea is highly unlikely to be implemented. Chances are, as soon as the film is made and shown, it will attract the attention of the Ministry of Magic and be found. However, just because there is no way to reveal wizard-related information in the Muggle world doesn't mean it can't be done the other way around.

If you open a magical movie theater in the wizarding world and copy Muggle movies, do you know if you can make money? Eisen thinks it should be fine. Because what the Muggle world is like, many wizards are particularly curious. It would be a good idea to let wizards understand how Muggles live through movies.

Perhaps, an Eisen magic film and television company can be opened in Diagon Alley. In this way, when the wizarding world is inevitably exposed to the Muggle world in the future, more wizards can learn how Muggles think through movies, which can reduce more unnecessary conflicts.

Previously, Eisen believed that the wizarding world would definitely be exposed. Because in terms of the speed of technological development in his previous life, the development of the Internet was too fast, but within twenty years, the era of the mobile Internet has already arrived.

Before the advent of the Internet era, ordinary people discovered that wizards cast spells. Maybe before things spread, the Ministry of Magic would come to the door and directly remember them clearly, so as to eliminate the exposure of wizards.

But in the future, every Muggle will have a mobile phone. Once a wizard is found to be using magic, it may spread throughout the Internet in an instant, letting hundreds of thousands or even tens of millions of people know. In this way, how will the Ministry of Magic deal with it?

If the Ministry of Magic does not deal with this possible situation in advance, the sudden meeting of two strange groups will inevitably lead to conflict. At that time, Eisen has no way to guess what serious consequences will be caused.

Therefore, using film and television companies as a bridge to connect the wizarding world and the Muggle world may be the most effective solution that Eisen can do at the moment.

"Muggle film company? Professor Eisen, aren't you a wizard? Why do you want to open a film company in the Muggle world?" After hearing Eisen's explanation, Hermione was surprised at first, and then became suspicious.

"Well, Hermione, you know, I am a Muggle-born wizard, and I have lived in the Muggle world for a while. Also, you are also a Muggle-born wizard!" Eisen did not answer directly, but said something The situation of himself and Hermione.

"Yes, Professor Eisen, I know there's a lot of money to be made in film companies, but we're wizards, aren't we?" Clearly, from Hermione's point of view, it wasn't much use for wizards to make too much money in the Muggle world.
