Hogwarts Passer-By Professor

In the next few days, as Harry, Ron and Hermione continued to worry, they found that Quirrell was much braver than they had imagined.

Even though they noticed that Quirrell looked a lot paler and thinner, he didn't look like he was broken by Snape.

Every day after class, Harry, Hermione, and Ron would put their ears to the door when passing through the corridor on the fourth floor, and listen carefully to see if there was Lu Wei's low roaring voice inside.

To the relief of the three, Lu Wei didn't have any accidents, and even Snape walked around the school every day, showing an extremely irritable look. It seemed that the Philosopher's Stone was still safe from Snape's possession.

Perhaps it was because Quirrell felt that Quirrell, who was directly facing Snape, was under tremendous pressure every day, so whether it was Harry, Ron, or even Hermione, every time they saw each other, they would smile encouragingly.

Even, Ron began to persuade other young wizards to stop laughing at Quirrell's stuttering flaw.

Of course, unlike Ron and Harry, Hermione, a top student, has more to do. In addition to paying attention to the Philosopher's Stone, she spent most of her time making review plans.

To be honest, Eisen was puzzled why Hermione was assigned to Gryffindor instead of Wen Klaw. Could it be that Hermione's courage (adventure) attribute is more prominent?

However, Harry and Ron couldn't care less when they saw Hermione color-coded all the notebooks.

Yes, in Ron and Harry's sense of time, there was still a long time before the exam. But for Hermione, it's only ten weeks.

After all, the school has a rule that a young wizard in the first grade must pass the exams of the courses he has learned before he can be promoted to the second grade. Therefore, reviewing is extremely important for Hermione.

Hermione had an argument with Ron about it. Unfortunately for Ron and Harry, however, the teachers sided with Hermione, giving them so much homework that it took them a long time to complain.

Eisen was very sympathetic to what happened to the little wizards, so he showed mercy and didn't assign much homework, just asking them to review what they had learned before.

After all, Eisen is just a professor of astronomy, and his courses are basically mixed credits for students. Therefore, he didn't want to embarrass them.

"It's terrible. I should have started reviewing a month ago. I don't know what happened to me..." In the library, Hermione frowned, showing annoyed look.

"Look, Harry, Hermione is nagging again!" Ron curled his lips, winking at Harry beside him.

Soon, it will be time for the Easter holidays. But for the trio, this holiday is far less joyous than the Christmas holiday. After all, they are busy with tons of homework assigned by their professors.

Therefore, Hermione, a top student, devoted all her time to reviewing. She either recited some knowledge about potions or practiced the movement of waving her wand every day. And Harry and Ron had no choice but to spend most of their spare time in the library with Hermione.

Well, although Harry and Ron were often yawned, there was always a lot of homework to be done, so they had to work hard.

This afternoon, when Eisen was studying ancient runes in the library, he was suddenly interrupted by the arrival of the trio. That's right, in order to learn more about alchemy, Eisen had to start dabbling in ancient runes and potions.

But obviously, although there has been some progress during this period of time, there is still a lot of difference in turning the knowledge I have learned into foundation. As for why Eisen spends time on this. Or because he wants to go a little deeper on the road of making magic props.

So far, Eisen has already stored several supernatural properties in his hands. But whether it's spellcasting characteristics or other characteristics, they are all excellent. During this period of time, Eisen has been speculating whether this is a grade, a magic item with a better grade, and a higher grade of extraordinary characteristics that can be reproduced.

On this point, if Eisen can engrave a higher-level extraordinary characteristic from the next accessible Philosopher's Stone, then it will be certain.

Therefore, even though Eisen has no way to confirm this conclusion now, he has already made a guess and plans to delve deeper. What if he can refine the Philosopher's Stone himself in the future?

"Why don't you review your homework quickly and come to see me?" Looking at Hermione who was a little proud in front of him, and Harry and Ron who were looking annoyed at the side, Eisen felt a little headache. At this time, I am a passerby, why can they still find me here!

"Professor Eisen, we have no way to remember these, what can you do?" Ron and Harry glanced at each other, and placed "A Thousand Miraculous Herbs and Mushrooms" in their hands in front of Eisen.

Seeing this, Hermione couldn't help but rolled her eyes.

"You mean, let me help you?" After hearing Harry's words, Eisen was stunned.

"Yes, Professor Eisen, I think you can help us." Ron nodded and winked at Eisen, making it look like he was being funny.

Eisen froze for a moment, and then saw Hermione holding back a smile behind the two, and knew that they were probably joking. However, with their personalities, how could they suddenly escape like this?

"Well, I do know a way to make it easier for you to review!" After pondering for a while, Eisen did not expose them, but said something meaningful.

"Ah, Professor Eisen, can you really help us?" Ron, who had no hope at first, suddenly became interested when he heard Eisen say this. Immediately, he asked impatiently. Even Harry and Hermione next to him looked at Eisen in surprise.

However, Eisen smiled and nodded without answering. Because he does know some methods, but, for them now, I'm afraid they won't be able to use them.

If they find that they can't use it after saying it, will they suffer a bigger blow!

"What's the solution, Eisen, don't be a fool!" Seeing Eisen's appearance, Ron became anxious.

"I know there are three ways." However, since they came to make fun of themselves, it doesn't matter if they say it. Thinking like this, Eisen stretched out three fingers.

Harry and Ron exchanged glances, surprise on their faces. Even Hermione at the side was very curious about the three ways Eisen could help them review their homework.

"The first way, do you know Felicia Potion?" When saying this, Eisen deliberately lowered his voice, and looked around for a while before anyone could say it.

"Felix Felicia? What's that?" Several people looked at each other, and finally Hermione who was the most curious asked.

"A very difficult potion, taking it can bring people good luck for the whole day, no matter what they do, they will feel smooth." Eisen said slowly.

To be honest, the Felicity Elixir that can add a lucky aura to people is indeed a bug-level potion. But it is a pity that this kind of potion is very difficult to brew, and it even takes several months, and there must be no mistakes in the steps, otherwise it will fail.

"But I don't think you can use it. Because it is not only very difficult to cook, but also takes a very long time, almost six months." Before a few people showed their happy expressions, Eisen put his The defect speaks out.
