Professor Rupert Hogwarts

Chapter 87
Ever since Eisen perfectly mastered the intangibility of phantoms, he has been able to travel around Hogwarts at will.

Since he has initially mastered the ability to transform between elements, Eisen's purpose in coming to Black Lake is to further master this ability.

Perhaps due to his in-depth study of human body deformation some time ago, Eisen found that the difficulty of transforming between elements has become much smaller.

When he came here to master the transformation technique and use other magic spells this time, Aisen found that it was exactly as he thought, and the changes between various elements were already very comfortable.

Of course, Eisen's experiment this time was only to master the ability to change elements more skillfully, not to attack the strength.Therefore, he did not show his attack power and destructive power.

For example, if he hadn't intentionally controlled the wind blade tornado that was transformed, it would definitely expand out of control.As for transforming into a fire tornado, Aisen actually felt that he had a lot of spare power, and could even turn it into a calendar fire tornado.

But obviously, there is no need for Eisen to directly expose this destructive power.

Of course, the reason why Eisen stopped was because he had spotted the trio of people sneaking towards this side from the God's perspective of observing the characteristics.

Because Aisen always has God's perspective on, he can safely experiment with the methods he has mastered without fear of being known.

So, what happened next was a scene that surprised the trio.

When they came to the Black Lake, they found that Professor Eisen was not observing the Black Lake, but looked directly at them, as if he knew they were coming here and was waiting for them here.

"Uh-Professor!" The three of them looked at each other, suddenly showing embarrassment.Finally, Harry stepped forward and said hello.

"If you're not going to have dinner, what are you doing here?" Looking at the trio in front of him, Eisen suddenly felt speechless.

"That's it, Professor Eisen. I want to borrow a book from the library, hoping to learn some knowledge about potions." Hermione looked at Eisen and said slightly embarrassed, "But, this This book is in the restricted section of the library, so I need a teacher to sign the note—"

After saying that, Hermione held out a piece of paper to Eisen.When Aisen looked at her, he might have felt that his lying was too shameful, so his face immediately turned red after he finished speaking.

Seeing Hermione's slightly embarrassed look, Essen didn't know what to say.

Theoretically, students can borrow books from the restricted book area after any teacher gives them their signature.But whether the signature of an astronomy professor would work or not, Eisen felt a bit doubtful.

"I must remind you that the restricted book area is too dangerous for second-year students." After signing the note with a quill pen, Aisen gave a solemn warning.

"I understand, Professor Eisen!" Hermione took the note and nodded quietly.Harry and Ron on the side suddenly showed a hint of joy when they saw that Hermione had gotten the signed note from Professor Eisen.

"By the way, why don't you go to Professor Lockhart to get a signed approval slip? His signature, a professor of Defense Against Dark Arts, should be more appropriate." As if he thought of something, Eisen asked quickly.

"Uh-" The three of them looked at each other, the smiles on their faces faltered, and then they told Eisen what happened during this period.

It turns out that ever since Lockhart was made to run away in confusion by the Cornish elf, his way of teaching had completely changed.

Originally, Lockhart would bring some creatures to teach students how to fight in practice, which was in line with the positioning of the Defense Against the Dark Arts course. However, after messing up once, his class content became reciting his own masterpiece.

Lockhart would read long passages from his books to his students in class, and sometimes even act out some dramatic passages.This made Harry complain during every Defense Against the Dark Arts class.

Because Lockhart likes to ask Harry to come on stage to play the characters in his books, such as the villagers healed by Lockhart, the Himalayan snowman suffering from colds, vampires, etc.

These experiences were a nightmare for Harry.But there was no way, who made Lockhart the Defense Against the Dark Arts professor, so Harry could only endure it.

Obviously, judging from the meaning of the trio's words, if they went to Lockhart to ask for a signed approval note, they would probably have to be tortured by Lockhart again.Therefore, after careful consideration, the trio did not look for Lockhart, but instead came to look for Eisen.

After listening to what several people said, the corners of Eisen's mouth couldn't help but twitch.Is this—Is Lockhart about to be exposed?With this in mind, he glanced at Hermione secretly and found a slightly depressed look on Hermione's face.

Obviously, Hermione at this time was also wondering why Lockhart would do this!
"By the way, take out the cards I gave you!" Then, Aisen stretched out his hand to the three of them.

The three of them were stunned for a moment, but then they thought of something, and they all took out the cards with the "∞" mark and put them in Aisen's hands.

Speaking of which, Eisen had secretly used cards to activate the transformation spell to help them.But now, he wants to make some changes.

After taking the three cards, Eisen pointed with his magic wand, then waved his hand, and a ray of light split into three and fell on the three cards.The "∞" mark on it suddenly shone brightly, then calmed down and returned to its original state.

"Remember to carry it with you and don't put it in the storage ring." After handing it over to the three of them, Aisen gave a serious warning.After seeing the three people put away their cards and nodded, Aisen did not forget to remind them, "If you encounter any danger, you can recite the password 'Protect', it can help you!"

"Thank you, Professor Eisen!" The three of them replied in unison, with joy on their faces.

"Okay, I won't deduct points from Gryffindor this time, but I want you to know that for students of your grade, it's best to go back to the Gryffindor lounge after eating. Don't spend the whole day Thinking about where to go for a night out and where to go for adventure!" Seeing the excitement of the three of them, Aisen directly poured cold water on their heads.

Harry and Ron's expressions froze, and Hermione even stuck out her tongue.Afterwards, the trio walked dejectedly towards Hogwarts Castle.

After Halloween, since the new season of Quidditch was about to begin, Harry had to focus part of his energy on Quidditch training while studying.

But due to the tight time schedule, Harry had already compressed his Quidditch training time quite a bit.This made Wood complain about Harry a lot.

On Friday morning, before other students had woken up, Hermione had already arrived at the library with Eisen's signed note.

The library was eerily quiet and dull.Mrs. Pince, the librarian, is extremely sensitive when dealing with students.

""Powerful Potion"?" After grabbing the note from Hermione's hand, Mrs. Pince muttered and looked at her suspiciously.The kind of gaze she was looking at made Hermione almost breathless.

But when she thought that Professor Eisen personally gave her the signed approval note, Hermione suppressed her discomfort and looked at it against Mrs. Pince's gaze.

After examining it, Mrs. Pince did not find that it was a forgery.Then, she walked between the bookshelves. After entering the restricted book area, she returned to Hermione within a few minutes.

Mrs. Pince said nothing and handed Hermione a thick book that seemed to be about to go moldy.It seems that the astronomy professor's signature is also very useful. Thinking like this, Hermione breathed a sigh of relief, quickly put the book away in her bag, and left the library as if nothing had happened.
