Hogwarts Passer-By Professor

When Eisen entered the Gryffindor common room through the portrait of the fat lady, he found that Harry, Ron and Hermione were already sitting on chairs and gathered together, seeming to be discussing something intensely.

"Professor Eisen, here—" Seeing Eisen approaching, Hermione immediately stood up and greeted her.

"How is it? Do you have any plans?" Eisen was also unceremonious, sitting directly next to Hermione, and then looked at Harry.

"We felt that we had to secretly get the Sorcerer's Stone before Snape!" Perhaps after arguing, they had already made a decision. So when Harry mentioned this method, neither Hermione nor Ron refuted.

Although they all knew that this kind of behavior was very dangerous and might even get them fired, Voldemort had already killed Harry's parents, so they couldn't let Snape get the Philosopher's Stone and welcome Voldemort back!

"Then, don't worry, I will go out with you tonight, so that we can definitely stop Snape." Eisen took the opportunity to say something.

"That's great, with the professor here, we will definitely succeed!" Ron breathed a sigh of relief when he heard that Eisen would follow them.

Even though she knew that Eisen had agreed to act with them, just to be on the safe side, Hermione was still flipping through all the notes, hoping to happen upon a spell that could be used later.

"By the way, how are you going to go out later?" As if suddenly thinking of something, Eisen looked at Harry. That's right, if you go out for a night tour at night, it's okay for Eisen himself, but if you bring a few little wizards with you, it's not justified anyway.

"We can use my invisibility cloak." Harry glanced at Hermione and Ron, and after a pause, he showed a happy expression, "Thankfully I got it back earlier!"

Eisen nodded and said nothing.

Time passed slowly, and the wizards in the Gryffindor common room also went back to their dormitories to sleep.

"Harry, you can get the Invisibility Cloak now!" Seeing this, Ron whispered a reminder to Harry.

Harry ran upstairs when he heard the sound, and came down within a few minutes.

Eisen turned his head to look over, and Harry was holding the Invisibility Cloak in his hand, besides that, he was also carrying a flute. Eisen was puzzled for a while, and then suddenly realized. Obviously, Harry wanted to use the flute to deal with Lu Wei just in case.

"Put this away, it has my magic imprint on it, so that I can follow you!" Seeing the posture of the three of them, Eisen knew that they were ready, then took out three playing cards, and left them on each of them with his magic wand. obtained the "∞" magic imprint, and then handed it over to three people.

The reason for this is that after the three of them put on the invisibility cloak, Eisen couldn't see them. So, in order to be able to follow them closely, Eisen thought of this way.

In simple terms, the three carry cards with his magic mark, so Eisen can locate their positions with a few cards. After all, Eisen is not strong enough to see through the Invisibility Cloak.

As for when Eisen's strength will be able to see through the invisibility cloak, this is something he cannot predict. Because Harry's Invisibility Cloak is said to be one of the Deathly Hallows, even the legendary Shendu can't find the person hidden by the Invisibility Cloak, of course he can't.

"Okay, I will use the illusion spell to hide and follow you. But please remember, our purpose is to get the Philosopher's Stone first, so if there is no danger, I will not make a move." See three people After accepting the poker with the magic mark, Eisen asked solemnly.

To be honest, these levels are reserved for trios after all. If Eisen had to go all out, he'd probably be able to pierce it from start to finish in a matter of minutes. But then, Harry, Ron, and Hermione, not having enough training would not be a good thing.

"What are you doing?" A voice suddenly came from the corner of the room. The three of Harry were startled, looked there and found that it was Neville. He's also clutching his pet, a rather ugly-looking toad.

The three seemed to think of something again, and hurriedly looked in the direction of Professor Eisen, only to find that there was no one there. Thinking of the disillusionment spell that the professor said earlier, they knew that he had been hidden. As the thoughts turned, the three of them breathed a sigh of relief in silence.

"It's nothing, Neville, we're not doing anything!" Harry said, already hiding the Invisibility Cloak behind his back.

"Are you planning to go out again?" Neville stared at the three of them, no matter how he looked at them, he felt that they were a little guilty.

"No, no!" Seeing that Professor Eisen really had no intention of showing up, Hermione waved her hand at Neville, "We don't want to go out? Neville, why don't you go to bed?"

Looking at the clock next to him, Harry was very anxious, I'm afraid Snape has already passed through the trap door!

"You can't go out, you will still be caught. If that happens, Gryffindor will be even more unlucky!" Neville, who had always been timid and timid, was extremely firm at this time.

"You don't understand, Neville, this matter is very important!" Harry really couldn't explain too much, but this time Neville was very firm and stopped them at anything he said.

"I won't let you do this, I want to compete with you." Neville said, took out his wand and blocked the portrait hole, staring at them.

To be honest, Eisen, who was hiding in the dark, was a little surprised when he saw this scene. In fact, for Eisen, he still sympathized with Neville. After all, his parents had been caught by Death Eaters and tortured with the Cruciatus Curse for a long time, and they had been lying half dead on the sickbed ever since.

Because of living in such a family environment, Neville was extremely inferior and timid since childhood. But unexpectedly, after entering Gryffindor for a year, Neville has already changed a little.

"Neville - get out of the way, don't be a fool!" Seeing Neville's behavior like this, Ron on the side suddenly became angry.

"I'm not a fool, I don't think you should break the school rules anymore!" Neville shook his head and refused to move away.

Seeing that she would continue to entangle with Neville, Hermione next to her couldn't bear it anymore.

"Neville, I'm so sorry for doing this!" Hermione drew out her wand and stepped forward, casting the Petrifying Curse directly on Neville.

"All petrified!" As Hermione's spell fell, Neville stood up straight, then swayed a few times and fell to the ground.

Neville's whole body was as hard as stone, which was obviously the effect of Hermione's petrification spell.

"What happened to him?" Ron asked in a low voice, looking a little startled at Hermione.

"I'm so sorry, Neville, it's the Petrifying Charm, I'm so sorry!" Hermione said, with a look of sadness on her face. Obviously, if it is not a critical moment, she would never say a spell to her friend.

They quickly stepped over Neville, put on the cloak of invisibility, and walked through the portrait hole. But Eisen was hiding in the dark and followed them closely.

With the convenience of the invisibility cloak to hide their figure, Harry and Ron soon came to the stairs leading to the fourth floor. Unexpectedly, they met Peeves here.

I don't know if it's because of his talent, or something else, but Peeves actually noticed some movement. Although he couldn't see Harry and the others, he still yelled.

"What should we do? Let Professor Eisen lure him away?" Ron whispered, with an ugly look on his face.

"Don't worry, let me do it!" At the critical moment, Harry tactfully shouted directly: "The bloody Barrow doesn't want to be seen by others, of course he has his reasons!"

[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. 】

That's right, Harry deliberately used a hoarse voice, pretending to be the bloody Lake Barrow to play Peeves.

Because the bloody Barrow is the leader of all the ghosts in Hogwarts school, and because he was very cruel during his lifetime, Peeves is very afraid of the bloody Barrow.

As a result, as Harry expected, Peeves was simply scared away.
