Ivan nodded indifferently, he hadn't planned to do anything in the first place anyway.

Back at the castle in Dahogwarts, Dumbledore suddenly stopped, reached out and patted Harry on the shoulder.

"You go back to the dormitory first, it's not convenient for you to participate in the rest of the matter."

Fudge nodded, anyway, it's all here, and he doesn't worry about Ivan and the others going to report again.

After the group parted, Ivan walked down the hallway to the Gryffindor House common room, Harry, Hermione, and Ron all looking worried.

"What if the three-headed dog on the fourth floor is found by Minister Fudge? Professor Dumbledore wouldn't be removed, right? Harry said.

"Don't worry, the professor will do it himself." Ivan said confidently that he didn't think Dumbledore was so easy to deal with.

Maybe in the confrontation with Fudge just now, Dumbledore might have some solution, otherwise he wouldn't have been so calm all the way over.

"But I don't think the professor can solve it on his own—" Hermione stopped abruptly and looked over Harry's shoulder.

"What's wrong? Is there anything on my face? Harry wondered.

"It's on the shoulder, it seems to have words." Ron said dumbfounded.

Ivan looked at the words made of golden points of light on it, the corners of his mouth twitched faintly, and he wanted to pretend not to see it, but unfortunately he was not the only one here.

"This must have been left behind by Professor Dumbledore. It says a secret passage... Fourth floor! Professor Dumbledore was telling us to take a shortcut through a secret passage to the fourth floor. Hermione said excitedly.

Harry and Ron were also excited, and they felt that they could do something again.

But where is this secret passage?

The three of them were confused for a while, and looked at Ivan in unison, since it was the message left by Dumbledore, it proved that someone must know the news of the secret passage.

Ivan was tempted to say that he didn't know anything, but considering that he would have to study at Hogwarts for some time to come, Dumbledore would inevitably wear small shoes, so he decided to solve this problem.

"You'd better be prepared, this secret passage is not easy to walk." Ivan sighed, he didn't understand how Dumbledore had guessed that he knew these secret passages.

Ivan ran with a few men before stopping in a small alley on the first floor, where there was a statue of a soldier with a sword.

Ivan stretched out his wand and tapped lightly on the wall next to the statue, and the soldier's statue jerked his sword up, startling Ron, and the stone bricks in the back wall were embedded in it, revealing a narrow passageway.

Inside is a strange space, with brick walls on the top, bottom, left and right, leading in all directions, and these walls are constantly moving and evolving as if they have life.

Just a moment when everyone paused, the space leading to the left had been completely flooded by a huge amount of bricks, and seeing that the space for standing was also about to be swallowed up, Ivan hurriedly pulled Hermione and the others away.

All the way to the right, the terrain was getting higher and higher, and the retreat behind him was also crowded by new bricks, Ivan suddenly crashed into a gray wall, Harry almost thought he was crazy, but Ivan's body went straight through the wall.

"Hurry up, this secret door will change!"

Ivan's voice came from the other end, and Harry and the others realized that this should be similar to the situation of the nine and three-quarters platform, so they no longer hesitated and crashed into it directly.

Entering it, Harry felt as if he had passed through a wall of water, and Hermione, who was running at the end, clearly felt that the pressure around him was gradually increasing, slowly becoming solidified, and they were about to turn back into real walls....

Fortunately, Hermione ran out at the last moment, and when she touched her back, it was already a solid wall.

"What if I hadn't been able to get out in time?" Hermione wondered.

"Then we won't see you." Ivan said solemnly.

Hermione was terrified, and Harry and Ron were also frightened, just as they swore in their hearts that they would never enter these dangerous secret passages again, they heard Ivan chuckle.

"I mean, you won't see you yet, you'll be teleported somewhere in the castle."

This is Hogwarts, and of course these mechanisms and secret doors are non-lethal, otherwise there are so many young wizards who have died in the past, and this school would have been closed long ago.

Hermione glared at Ivan angrily, if it weren't for the urgency of the situation, they would have joined forces and beaten him up.

"Where are we?" Harry looked left and right.

"It's the fourth floor, of course." Ivan and a few people quickly found the corridor that was forbidden to enter.

The wooden gate was still closed, but they all knew that there was a fierce and brutal three-headed dog inside.

"Harry, do you still have the music box I gave you?" Ivan turned his head to look behind him.

"Of course, that's a great gift..."Harry didn't know what Ivan was up to, but he took it out of his pocket anyway.

"By the way, Hagrid once said that Lowe likes to listen to music and will fall asleep when he listens to it!" Hermione immediately remembered, and Harry and Ron were also excited, so they wouldn't have to deal with the three-headed dog.

Ivan nodded, with this music box, he didn't need to use the Transfiguration Charm to make a temporary musical instrument.

Pushing open the wooden door of the hallway, Ivan motioned for Harry to open the music box, only to find that the three-headed dog Lou Wei had fallen asleep with his eyes closed.

However, the sound when entering the door still had some effect, and Lu Wei's eyelids moved slightly, and he was about to wake up when he saw it.

Without prompting, Harry had already opened the music box when Lou Wei was moving again, and the cheerful Christmas song resounded in the hallway, and Lu Wei fell asleep after hearing the music.

Everyone breathed a sigh of relief, but in the face of such a big three-headed dog, they didn't know what to do for a while.

"I mean, why don't you forget it? How are we going to get such a big three-headed dog outside? Ron swallowed as he looked at Lou Wei's three large mouths full of fangs, and he couldn't think of any way to hide it.

"Isn't there a trapdoor here?" Ignoring Ron, Ivan walked straight to the trapdoor, opened it, and doubled the trapdoor with an extension charm.

If it weren't for Ivan's magic power and spellcasting level greatly increased after completing the fusion ritual, it would not have been possible to complete it.

"Are you going to just throw it away?" Hermione was a little worried about whether Lowe would just fall to his death or make some noise down there.

"So something else needs to be done," Ivan said.
