Hogwarts Passer-By Professor

The three of them discussed until late at night, and finally fell asleep. Early the next morning, the trio went to find Professor Eisen after eating. But unfortunately, no one was seen by the three of them, either in the faculty dormitory or in Eisen's office.

After the last class of the afternoon, the trio went to Hagrid's cabin together.

After Harry stepped forward and knocked on Hagrid's door, the three of them were invited in by the enthusiastic Hagrid.

"Hey, Hagrid, your house has changed a lot!" As soon as he entered Hagrid's hut, Ron looked around the hut in surprise.

Indeed, Hagrid's hut seemed to have been sorted out. Although it still looked a little messy, it seemed to be a lot cleaner overall.

Moreover, a plush blanket was spread on the dark floor, and there were tufts of unicorn hair on it. I don't know what the situation was.

"Oh, you said this." Hagrid put a pot of pumpkin juice and a few cups on the table, and explained casually, "Professor Eisen commissioned me to help him collect it. It's not a complicated thing, is it?" ?”

"Professor Eisen?" Harry's eyes lit up, and he quickly took up the topic.

"That's right, last time Professor Eisen helped me with the pumpkins I planted. It worked well for the Halloween banquet. He wanted to collect some unicorn hair for research, so he found me..." Hagrid said, revealing A little bit of pride.

That's right, for Eisen, when researching and making alchemy props, he found that the hair of magical animals would be a good raw material.

As it happens, Hagrid spends his days dealing with all kinds of magical animals, so Eisen entrusts Hagrid to help him collect some unicorn hair.

"So, Hagrid, do you know where Professor Eisen is?" Seeing that Hagrid brought up Professor Eisen on his own initiative, Hermione exchanged a glance with her little friend and brought it up.

"Isn't he in the office?" Hagrid gave a surprised look.

"No, we went to the staff room and the office to look for him, but we couldn't find him!" Ron replied after gulping pumpkin juice from a glass and belching.

"By the way, do you have anything to do with Professor Eisen?" Hagrid seemed to have thought of something, and suddenly looked at the three of them suspiciously.

Harry was taken aback for a moment, and after exchanging glances with Ron and Hermione, he told about Mrs. Norris being attacked on Halloween and the Chamber of Secrets being opened.

But the three of them didn't notice that Hagrid's face turned pale with Harry's words.

"The Chamber of Secrets? The Heir?" Hagrid rolled his eyes, wondering how to end the subject.

"Yes, we found some clues—"

"Listen, there are no secret rooms, and there are no monsters. You can't know about these, it's too dangerous!" Just as Harry was talking, he was considering whether to tell Hagrid that he was a Snakemouth. Unexpectedly, Hagrid directly interrupted him excitedly.

"It was an accident, no one would have expected such a thing to happen!" Hagrid muttered, stood up and threw the trio out of the hut.

After being kicked out of Hagrid's hut, the three of them stood on the ground and looked at each other for a moment.

"He's definitely hiding something!" Ron looked at Harry and Hermione with a look of exasperation on his face.

"Obviously, we can all see that!" Harry and Hermione shrugged without saying much.

"But, where did Professor Eisen go?" The three of them walked towards Hogwarts Castle, but Hermione still couldn't help asking such questions.

"I don't know, maybe there is something to be busy with!" Harry shook his head, speculating like this.

Before the three of them entered the foyer, two figures came from a distance, "Wow, I seem to hear you talking about Professor Eisen, does he have any amazing works?"

The twin brothers Weiss came to the front of the trio laughing, winking and frowning from time to time, making a funny shepherd.

"Nothing!" Ron said coldly, not seeing the joy of big brother at all.

No way, it can only be said that Fred and George were born with prank talents. Ron was spoofed by them since he was a child, and he has already had a psychological shadow for so many years.

"Oh, come on, we also admire Professor Eisen!" Fred stepped forward and put his arms around Ron's shoulders.

"That's right, I admire it very much! You know, the idea of ​​the chime recorder came from Professor Eisen!" George had a smirk on his face at the right time.

"What did you say—Professor Eisen told you about the chirping recorder?" As if his tail had been stepped on, Ron looked at the two in horror, as if he couldn't believe what he heard from their mouths.

Harry on the side also stared at Fred and George dumbfounded.

He knew how many little wizards in Gryffindor were bullied by the crowing of the rooster before they woke up. Even Ron has been spoofed more than once.

But they never expected that Fred and George actually said that this prank actually came from Professor Eisen.

"This—" Ron opened his mouth, not knowing what to say for a moment.

"Well, we saw Hagrid collecting unicorn hair for Professor Eisen in Hagrid's hut, maybe to make something!" Harry simply told what he had learned from Hagrid's hut earlier.

"Collect unicorn hair to make something?" Fred and George had puzzled looks on their faces, obviously unable to guess what Eisen's purpose was.

"So, do you see where Professor Eisen is? We have something to do with him!" Seeing Fred and George's expressions, Harry hurriedly asked.

"Uh, well, maybe you can go to the Black Lake to look for it, we saw where Professor Eisen is!" Fred recovered and gave an answer.

"That's right, maybe Professor Eisen is observing how to catch the mermaid in the Black Lake." George nodded, with a strange look on his face, as if he wanted to encourage them to do so.

Black Lake——

The three of them looked at each other with surprised expressions.

That's right, for Hogwarts students, there are two mysterious areas of the school. One is the Forbidden Forest, where there are some dangerous magical creatures such as trolls, hippogriffs, and titans. The other is Black Lake.

There are some aquatic magical creatures hidden in the Black Lake, and part of the waters has been designated as a nature reserve for magical creatures by Hogwarts.

But what the trio couldn't figure out was what Professor Eisen was doing in Black Lake. Could it be that, as George said, he was observing the mermaid in the Black Lake?

Afterwards, the three of them quietly moved towards the Black Lake with cautious steps.

The night was approaching, which added a lot of mystery to Hogwarts. Standing by the edge of the black lake, a gust of cold wind blew in, and Eisen felt extremely transparent all over his body.

Eisen stretched out his wand and pointed it at the surface of the Black Lake, a stream of water was sucked out of thin air, and then turned into a waterspout, spinning continuously.

With the use of the transformation technique, the waterspout in front of him was covered with a layer of crystal mist, and then quickly transformed into a firespout, emitting astonishing heat, steaming on the surface of the lake.

Then, the fire tornado quickly turned into a wind blade tornado. While tearing the air, it continuously sucks the lake water into it.

Since Eisen's transfiguration has improved, he has fully mastered the once difficult-to-control spell.

As the mind turned, the windblade tornado in front of him completely turned into a cloud of mist. Then Eisen disappeared in place in an instant, appearing above the cloud of mist.

After casting a levitation spell on himself, the mist rolled and changed at the same time, and crystallized little by little, as if it had substance, directly holding Eisen in midair. It looked as if Eisen was riding a cloud.

With another thought, Eisen disappeared in mid-air and reappeared on the edge of the black lake. The mist in the lake turned into streams of water and fell into it again, completely calming down.
