Hogwarts passer-by professor

Chapter 290 Inspiration
At noon the next day, Aisen returned the books he borrowed from the library. When he arrived at the auditorium, he found that the entire auditorium was extremely noisy and lively.

Eisen thought that the little wizards were still discussing the Triwizard Tournament and the clues to the golden eggs in the hands of the warriors, but he found that what they were discussing had turned into a Yule Ball.

At this time, Eisen suddenly realized that the little wizards had been notified by the school.

Regarding the upcoming Yule Ball, it is obvious that the professors attach more importance to it than the little wizards expected.The professors strictly required the little wizards not to cause trouble, which aroused a lot of discussion.

In fact, this can be said. After all, this Yule Ball is part of the tradition of the Triwizard Tournament. Therefore, I want to leave a good impression and a perfect display on the teachers and students of Beauxbatons and Durmstrang. You are the best way.

"Professor Eisen, is the Yule Ball a tradition of the Triwizard Tournament?" Feeling the change in the atmosphere in the castle, Harry couldn't help but ask Eisen.

"That's right, Fred and George were both warned by Professor McGonagall -" Ron showed a smile on his face, "she told them not to do those pranks at the Yule Ball!"

"Professor Eisen, Professor McGonagall said that the warriors of the Triwizard Tournament should serve as representatives of the school and find themselves a dance partner-" Hermione said, looking at Eisen eagerly, as if she was hinting at something.

Glancing at Harry and Ron, the two stopped all movements and stared at Eisen with curious eyes, as if they wanted to know what he would do.

"Yes, I will choose a dance partner to attend the Yule Ball." Eisen said with the corners of his mouth raised slightly. After taking a deep look at Hermione, he turned to look at Harry and Ron. "Who do you think I invite more?" Is it suitable?"

"Uh, Professor, what do you think, Ai——" Ron said enthusiastically, but was interrupted by Harry mid-sentence.Ron stopped and looked at Harry, who was pulling his arm hard, with a puzzled look on his face, and saw the other person motioning in Hermione's direction.

Ron looked over and saw Hermione glaring at him fiercely.

"Uh, Professor Eisen, we think Hermione is very suitable, right, Harry!" After swallowing, Ron patted Harry on the shoulder, gave him a wink, and then looked at Eisen solemnly. Sen said.

"Well, yes, if Professor Eisen has no choice, I think Hermione is very suitable!" Harry said and glanced at Hermione, and found that she was staring at Professor Eisen with a silly smile on her face.

The smile on Eisen's lips spread, and when he looked at Hermione, he found that her fair face was gradually stained with a layer of red.But she did not turn her head, but looked at Aisen with an expectant expression.

"Well, yes, that's right! I don't have a dance partner yet!" Eisen picked up the bowl and took a big sip of seafood soup, nodded to Hermione, paused, and continued, "So, Hermione Granger Madam, will you be my partner at the Yule Ball?"

"Professor, I do!" As if hearing the expected answer, Hermione's eyes lit up, she whispered and then quickly lowered her head.

At this moment, her face was turning red.

Smiling and shaking his head, Eisen said nothing. He reached out and knocked on the table. A faint silver light emerged and fell on Hermione, calming her excitement.

"By the way, have you two decided who you want to invite as your dance partner?" Eisen looked at Harry and Ron.

"The two of us!" Harry and Ron looked at each other after meeting each other.

"Well, the school does not force everyone to attend the prom." Eisen said slowly, "However, it is rare to hold a prom this year. I think all students in grade four and above will stay and participate!"

"Then we also want to invite partners to dance on the Christmas ball?" Harry had a look of anticipation and confusion on his face.

"So that's it -" Ron seemed to have thought of something and suddenly exclaimed, "No wonder my mother made me wear that dress with a ruffle that seemed to be moldy on the neckline. They already knew it. !"

After finishing speaking, Ron seemed to see himself wearing a purple robe that looked like a lady's dress, and his face suddenly turned pale.

"Um—Professor Eisen, can you not go dancing?" Ron seemed nervous.

"It's the Christmas ball!" Eisen raised his eyebrows and cast a spell casually, filling the bowl with seafood again. "No one will care what dress you wear-"

After casually comforting him, Aisen had a flash of inspiration in his mind, seemed to have thought of something, and then stopped talking.He just stared blankly at the bowl in his hand, lost in thought.

He cast a spell just now. What kind of spell was it? By the way, it was a continuation spell!A very common spell in daily life.But the effect of this spell is very magical.

Because in Eisen's opinion, there are many spells in the wizarding world that violate the conservation of mass.For example, the transfiguration spell can make the existing food more abundant, and the refill spell can continuously refill the container with drinks or soup.

There are also some, like some of the swelling spells Hagrid cast on grown pumpkins and so on.

Breaking down the details, this type of magical spells do exist in the wizarding world.In other words, if Eisen wants to study a spell with similar effects, he can definitely do it.

Of course, the reason why I say these things does not mean that Eisen will be obsessed with why those spells violate the conservation of mass or the conservation of energy.

Eisen has actually known this for a long time. After all, the magic in this world can travel through time and space, so what can't it do?
However, the Continuing Mantra that he accidentally released before made him suddenly think of something - if he researched and disassembled the Continuing Mantra, some of its principles seemed to be applicable to his newly developed Above the contract enchantment.

Think about it, if Eisen transforms a cup, dismantles the magical effect of the curse, and uses runes to express it on the cup, then the drink in the cup will never be drinkable. Finished?
To put it another way, if this automatic recovery magic effect is applied to his contract spell, does it mean that the connection between him and "The Book of Essen" can still be restored if it is severed or reversed? What about automatic recovery?

If there is a constant automatic recovery effect on the contractual connection between Eisen and "The Book of Eisen", wouldn't that be much stronger than any increase in the stability of the contractual connection between the two?

Of course, Eisen knew that this idea was just an idea at the moment.After all, the refilling spell is a magic that targets drinks, water and other liquids in the container, and what he needs is a magic that targets contracts.

Therefore, whether new spells can be researched, Eisen still needs to conduct experiments.

"Professor, professor!" Harry's voice rang in Eisen's ears, bringing back his wandering thoughts.

"Huh?" Aisen looked serious. He saw the trio looking at him with puzzled faces, as if wondering why he was in a daze. "Okay, let's go to class after dinner. I still have some things to do. Woolen cloth!"

Without looking at their reactions after speaking, Eisen went straight to the second floor.

After passing through the school hospital and the History of Magic classroom, Eisen paused, but then remembered a potion called "Eternal Potion", which seemed very interesting.

This potion is a magic potion that lasts forever or can never be used up.Let’s not talk about the fact that it is always effective. Let’s just say that it can never be used up. Isn’t it the same effect as automatically casting the replenishment spell?
Afterwards, Aisen continued to move forward, and after arriving at the library, he opened the door and walked in.

……

Half an hour later, Eisen sat at a reading table and closed the "Advanced Potion Making" book in front of him.

His previous guess was correct. After studying the production process of "Eternal Potion", Eisen discovered that before the end of the production process, this potion not only needs to cast a spell to make it effective, but also needs to use a refilling spell. Variation spell.

Using this method to make a steady stream of magic potions surprised Eisen.

However, the effect of this medicine made Aisen feel that it was useless. It could only treat most common diseases.Obviously, it is basically impossible to produce a steady stream of blessing elixir using the same method.

In other words, in the current wizarding world, no one has been able to study it to that point.

After all, although the eternal potion, an inexhaustible magic potion, can only cure most common diseases, it is still a magic potion after all.Since it is a magic potion and can never be used up, it is equivalent to opening a hole in this field.

In this way, it is necessary to make a magical potion or other high-level magic potion into a potion that can never be used up. When it will be researched, Aisen cannot say, but as long as he keeps researching, he will succeed even if the probability of success is small. of.

In this way, I can write it down and study it when I have time in the future.But now, Aisen's attention still has to be on the renewal spell.

Well——, in order to research a new magic spell, we must first thoroughly understand the continuation curse and conduct dismantling and research on the continuation curse.

After putting the books back on the shelves, Aisen turned and left the library.
