boom!

The sound of falling bookshelves was enough to wake up the entire castle.

At this moment, the three Fred, who were playing a mouse-and-cat game with Filch on the third floor of the castle, were also taken aback by the loud noise, and stopped one after another, listening to the surrounding sounds with their ears up.

Originally, Filch, who was still pursuing a few people, also stopped and looked in the direction of the sound in amazement.

"The sound seems to be coming from the direction of the fifth floor." Filch muttered to himself, and he immediately turned and hurried towards the library.

"What happened to the noise just now?" George was the first to restrain his curiosity.

"I don't know, maybe Albert got it out. Go back to the lounge first." Fred said decisively, "Before the sound just now drew other professors over, go back quickly."

"Quick!" George whispered, and the three began to run at full speed along the corridor. They had to return to the common room before the professors appeared. Because Albert had told them that the professor at Hogwarts had the ability to see through the phantom curse on them.

Running through corridor after corridor, the three of them went to the seventh floor through the secret passage beside the corridor. On the way, Lee Jordan said again: "Are we going to the meeting point? What about Albert?"

"That guy must have ran away before us."

"Go straight back to the common room."

In fact, their approach was quite correct. Soon after the sound sounded, several professors in the castle were awakened by the sound and came over to check the situation.

In the hallway, the portraits in the aisle were running back and forth, trying to figure out what was going on.

By the time Filch inspected the fifth floor, Albert had already fled the scene of the crime, and moved faster than them.

Before leaving, Albert did not forget to close the library entrance.

It was also for this reason that Filch could not find the scene of the crime for a while. He just probably knew where the sound came from, but when he checked in the past, he found nothing.

The culprit responsible for all this is hurried to the Gryffindor common room.

Albert tried not to make any noise, but the people in the portrait were awakened by the sound just now. After hearing the slight footsteps, they all turned their faces curiously and looked at the corridor where there was nothing.

After going upstairs, Albert walked halfway down the corridor, then lifted a tapestry on the wall, and walked up a narrower staircase, which was a shortcut to the eighth floor.

As for Fred and the others, they carry a live spot map and should not be caught, but Albert is not worried about their safety at all.

When he came near the entrance of the common room, he didn't release the magic on his body, and he waited for Fred here.

A few minutes later, a few people hurried to look at Albert, who was still waiting for them, and asked puzzledly: "Why don't you enter the lounge?"

"When invisible, the fat lady won't open the door for us." Albert reminded: "Come with me, go to the responsive house first. Just in case, we still don't want to be seen."

The three of Fred looked confused, but they still followed Albert to the responsive room. In this case, they were willing to trust Albert's judgment. After all, Albert had a much better brain than them. He did this. There must be a reason.

On the other side, Filch was patrolling the library, because the sound just now did make the sound of collapsing to the library shelf. However, when Filch entered the library, he didn't find any signs of collapsed bookshelves here.

Yes, no, even in the forbidden book area, there is still no sign of bookshelves collapsing, as if the sound had never happened.

At this moment, Filch knew that he was being played, yes, he was played, just like the helmet glued to the floor on the fourth floor, and the **** big dung egg that was thrown in the corridor, including here. All the sounds are people playing with themselves.

Yes, it was the **** he was chasing just now, Filch vaguely guessed who they were.

The Gryffindor twins, although there was no evidence, Filch had a hunch that it was the two of them who did it.

"Filch? What happened?"

Snape walked into the library with a gloomy face in a gray shirt-style pajama.

"I just heard a noise and came over to check the situation. I think it's probably caused by some students deliberately." Filch turned and looked at Snape and whispered, "I was just chasing them. Several students were wandering in the castle in the middle of the night, Professor."

"Students, fine, we will catch them." Snape looked around the library and stepped into the restricted area to take a look. He didn't find any signs of the bookshelf collapsing.

"What's the matter?" Professor McGonagall walked in quickly. She was wearing a checkered dressing gown and a hair net. She glanced across the library with a serious look. She obviously thought that the sound just now was a bit like a bookcase collapsed. The sound.

"Someone was in the library, in the restricted book zone." Filch said immediately: "I just looked for a few students who wandered around the school in the middle of the night. They should be in a group, and they are probably... Gryffindor student."

"Do you have any evidence?" Professor McGonagall asked with a frown.

"What's going on here." Smith appeared outside the door in a bronze pajamas. "Is this preparing for a pajama party?"

"Someone is making a loud noise Professor here. We suspect that the students made it. There are several students wandering around the school tonight." Filch said in a low voice. He rarely speaks loudly in front of the professors.

"Filch, did you just say that it was probably made by a Gryffindor student?" Professor McGonagall asked. "Is there any evidence?"

"You can ask the gatekeeper at the entrance to Gryffindor." Snape said suddenly. He would love to see the students at Hogwarts unlucky and get points deducted.

"Well, this is a good idea." Filch nodded.

Professor McGonagall frowned slightly, but ultimately did not object.

Several professors moved towards the eighth floor one after another, and found Gryffindor's gatekeeper Fat Lady at the entrance of Gryffindor.

"Madam, did anyone enter the lounge just now?" Professor McGonagall asked.

"No," said the fat lady.

"Are there any students leaving?" Snape asked.

"Yes." said the fat lady.

"Who are they?" Filch asked impatiently.

"I don't know, they are invisible." The fat lady said.

"Just look at who is not in the dormitory to know who just wandered in the castle." Snape suggested maliciously.

"This will wake up sleeping students." Professor McGonagall obviously disagrees with this approach.

"Only students in the upper grades may use the phantom spell." Professor Smith suddenly reminded, "I think they didn't enter the common room. They should be still somewhere in the castle. We will find those naughty students. ."

Smith obviously disagrees with waking up other students. However, in fact, a large part of the students have been awakened by the sound just now.

"I will find them." Filch gritted his teeth.

However ~www.mtlnovel.com~ Filch and several other professors searched the castle several times, and even searched the secret passages, but found nothing.

okay!

In fact, there are two dead ghosts.

A girl from Ravenclaw and a boy from Hufflepuff became a survivor. The couple were actually dating in a secret passage, and they were caught by Filch who suddenly broke in.

Each was deducted fifty points.

But after questioning, it was obviously not the group of people that Filch was looking for.

As for the group of Gryffindor students that Filch was looking for?

Almost the entire castle was turned upside down by the professors, but still no trace of the Gryffindor students were found.

No way, no one would let them know that there is still a hidden room on the eighth floor of the castle. Its name is the Room for All Requests.
