Hogwarts Passer-By Professor

Since the new school year had just started, Eisen didn't go to the Response Room to practice the spell when he went back at night, but went to bed early.

Eisen understands that although his Transfiguration has made some breakthroughs, it still takes a long time to master the new skills perfectly. Therefore, there is no need to rush for a while.

It is already the second school year for the trio of saviors to enroll. If there is no accident, then the next big event will revolve around the Slytherin Chamber of Secrets.

Of course, a key prop is the diary given to Ginny by Lucius Malfoss. Speaking of it, this diary is not simple, it is actually the first Horcrux that Voldemort made.

When Voldemort was still in school, he opened the Slytherin Chamber of Secrets and controlled the basilisk with the talent of the basilisk, and then murdered a Muggle-born witch Myrtle Warren, that is, has been draining the pipe 'Weeping Myrtle' lingers within. It was this murder that he used to split his soul and store it in his diary to create the first Horcrux.

Moreover, Voldemort was very cunning. He blamed the murder on Aragog, Hagrid's acromantula, which caused Hagrid to be expelled from Hogwarts.

Later, Voldemort handed over the first Horcrux diary he made to his subordinate Lucius Malfoy for safekeeping. Right now, since the Ministry of Magic has started a large-scale search of dangerous items, Lucius secretly slipped it to Ginny when he was at the Lihen Bookstore.

The next thing, if there is no accident, the diary will use Ginny's hand to make troubles in Hogwarts school, and finally almost come back to life.

The next morning, Eisen went to the auditorium to have breakfast as usual.

Under the enchanted ceiling, four long tables were laden with dishes. While the students were eating, they were talking about something with great interest. Pay a little attention and you'll see that the center of the conversation is Harry and Ron.

Yes, for Harry and Ron to come to Hogwarts in a flying car, most of the students gave them amazed and envious eyes.

However, Eisen noticed that when Hermione was flipping through a copy of "Traveling with Vampires", her expression was very stern. Even saying hello didn't give Harry a good face.

It seemed that Hermione, who was a good student, still had a hard time with Harry and Ron's outrageous way of coming to school.

Eisen, who had just eaten a piece of bread and was drinking milk, suddenly and acutely heard a buzzing noise. Looking up, I saw hundreds of owls flying from outside, circling over the auditorium.

Then, one by one, they threw the packages or letters onto the four long tables, and were caught by the students who were chatting one by one. Obviously, this is a gift or letter from the student's parents to the student.

"Errol!" Just then, Ron yelled and caught Eisen's attention.

I saw a gray owl lying on the table with a red letter in its beak.

"Oh, no—" As if thinking of something horrific, Ron couldn't help but put his hands on his head.

"Don't worry, it's still alive!" Harry poked the owl with his hand, and when he found that the owl was still moving, he patted Ron on the shoulder comfortingly.

"No, that's what I was talking about!" Ron pointed to the red envelope on Errol's mouth, shaking his head with a troubled expression.

"What—what's the matter?" Harry showed a puzzled expression, and even Hermione was attracted to him.

Looking at this scene, a smile appeared on Eisen's face. If I'm not mistaken, the red envelope must be the Howler letter. Well, it's like watching a play!

"She—my mother sent me a Howler letter." Ron swallowed hard, wondering if he should open it or not.

"Ron, you'd better open it, it's worse if you don't, my grandma sent me a Howler letter, I didn't open it, and it turned out - horrible." Neville tried to persuade Ron, but he didn't know if Thinking of the terrible consequences, he took a deep breath.

"What is a Howler Letter?" Seeing the terrified expressions of Ron and Neville, Harry felt a little strange. Could it be that there is danger?

[To be honest, I have been using Yeguo to read and read books recently, change sources, and read aloud with many timbres, yeguoyuedu Android and Apple are all available. 】

The red letter was already smoking, and Ron's brow was sweating, and he was so focused on it that he ignored Harry's question.

"Open it quickly, or there will be no time!" Neville urged in a low voice.

There is no way, this kind of thing cannot be avoided. Ron was terrified as soon as possible, but still stretched out his trembling hands, took the envelope from Errol's mouth, and gently tore it open.

The roar immediately resounded throughout the auditorium, and Harry was stunned for a moment. He finally knew what a Howler letter was. Neville next to him blocked his ears in advance, and Hermione quickly covered her ears after being startled.

"Come on, Ron Weiss, you are really capable! Stealing the car, I wouldn't be surprised if they fired you, and see what I do with you. You probably didn't even think about it, me and How did your father feel when he found out that the car was gone..."

This was Mrs. Weasley's voice, the volume was a hundred times louder than usual, and even the dishes and spoons on the table were rattling. To be honest, at this moment, Eisen was also a little dumbfounded.

Because he knew this famous scene, and he had seen such a scene in a movie deep in his memory, but he didn't remember that the roaring letter was so powerful that it almost shook the entire auditorium.

Everyone in the auditorium fell silent for an instant, and then saw Ron huddled in a chair, only seeing a flushed forehead.

"Received Dumbledore's letter last night, your father almost died of shame. How could you do such a thing, you and Harry almost lost their lives—" The sound of hitting the eardrums made Harry shrink back down.

"Your father will be censored at the Ministry of Magic, and it's all your fault. If you don't follow the rules, we'll bring you back right away!" The voice of the roaring letter finally stopped, and then Eisen's slightly dull gaze Burning, curling and dissipating into ashes.

Turning his gaze to Ron and Harry, he saw that they didn't come back to their senses for a long while.

Afterwards, whispers continued to ring out in the surrounding area, and the quiet auditorium gradually became lively again.

"Don't you expect anything else, don't think about it, you're—" Hermione took away her hand from her ears, closed "Sailing with Vampires" and glared at Ron.

"I see, stop talking!" Ron interrupted Hermione's reprimand angrily.

After breakfast, Professor McGonagall handed out Gryffindor's class schedule one by one, and Harry and the others will have herbal medicine as their first class.

As for Eisen himself, he came to the library on the second floor.

After finding a copy of "The Mystery of Transfiguration" from the bookshelf, Eisen sat at the table.

However, Eisen was not in a hurry to read this book, but was thinking about the scene that happened in the auditorium earlier.

All this time, Eisen didn't think much about it, until he saw the power of the roaring letter this time, he suddenly had some ideas. That is to apply the roar letter to the battle.

Yes, this idea seems very ridiculous, but if you think about it from another angle, there is definitely room for transformation of the Howling Letter.

For example, the roar letter can only be triggered after it is disassembled, but if it is transformed and touched the target, it will be triggered directly. Isn't that very sour.

However, Eisen was immediately discouraged when he thought that there was a magic spell to block ears in the wizarding world. Because even if it is really transformed into an instant-triggered roar letter, it seems that it can only be used to sneak attack when the opponent is not paying attention. In this case, the restriction is too great.

This also means that owls cannot be used to send messages to the target, and the roaring letter must be sent to the target with the Flying Curse at close range. But if it's a close-range confrontation, isn't it too low-level to throw a roar letter? After all, if you have this skill, you can just use the attack spell directly!

Shaking his head and clearing the thought from his mind, Eisen focused on the book in his hand, and gradually became addicted to it.
