HP: I just wanted to drop out of school, but I saved the world

"Meow-"

The shrill and sharp meow of the cat was still clearly audible through the thick wall. Mrs. Norris walked back and forth in confusion at the door, scratching the bricks with her sharp claws, making a sound like nails scratching on glass, which made the students in the classroom tremble uncomfortably, but they did not dare to cover their ears.

"Oh no," Fred and George said in unison. "There's a flaw in our brilliant design - the painting isn't animal-proof. If the cat gets hold of the painting, it'll be able to access the secret door."

Draco, who was beside Jian Yu, moved. He looked like he wanted to rush out and scold the two of them for being idiots, but he gritted his teeth and endured it.

“Meow—meow—”

Mrs. Norris's cries became louder and louder, and the students could all imagine her patrolling posture, her skinny body pressed against the wall and sniffing carefully, her bulging lightbulb eyes full of ill intentions - she would stand up and scratch the wall, over and over again, to remind her master Filch that the students' secret base was hidden in the wall.

"What should we do?" Ron said in panic, "Did it smell our remaining scent?"

Harry beside him pulled his sleeve, signaling him to be quiet.

For a moment, the classroom became quiet again. No one spoke, and no one even dared to breathe loudly.

"Who's there?! Come out!!"

Filch's hoarse and rough voice was clearly audible. It was obvious that he and Mrs. Norris had worked well together for many years and had already discovered something unusual. Seeing that there was no movement in the corridor, he began to knock on the wall with his knuckles to see if there were any hidden doors or secret passages in the wall so as to catch the students who were wandering at night.

"Boom boom boom——"

The knocking sounds seemed to be beating on their hearts, and as the sound grew louder, they realized that Filch was hitting the wall with his palms or fists. He must have discovered the secret!

"I'm going to hang you up. I have chains and handcuffs hanging from the ceiling of my office ready—"

His eerie voice sounded like the whisper of a demon.

Through the faint light of the soundproofing spell that was constantly being cast, Jian Yu discovered that everyone's face looked extremely unhappy.

Draco's face was wrinkled into a ball, just like Slughorn's multi-layered belly, Blaise was sweating profusely, and his brows were tightly knitted; over there, Harry and Ron's hands were tightly grasping the table leg, as if the table leg could give them infinite confidence; the huddled eagles and badgers hugged each other for comfort, muttering to themselves.

"Merlin - we're going to be discovered, this will get us expelled!"

Ron's trembling voice floated out from the side, which was immediately glared at by Draco, who cursed in a low voice:

"Idiot! Is that all you Gryffindors are capable of? Dumbledore can't possibly expel so many people at the same time!"

Jian Yu looked at him with appreciation.

I didn't expect that Draco had grown a little smarter after entering the third grade!

This is indeed impossible, because only the culprit will be caught and made an example of -

Yes, it was her.

Filch, who was outside the wall, had already spotted the mural at the corner. He spoke with confusion:

"Has this painting appeared before?"

As the manager of the castle, he should have a memory of every painting, but he had never seen this one.

His heavy footsteps stopped, and he seemed to be carefully observing the mural, looking for flaws in it.

The dung balls inside the door were already in place, ready for Red Hat to start throwing as soon as Filch touched the mural.

Sure enough, he reached out and knocked on the frame—

The red hat seemed to come alive, and it started dancing while shouting "crazy idiot". It danced and threw the dung balls in its hand out of the frame. Filch was caught off guard and was drenched by the exploding dung balls.

"Disgusting scum, disgusting!" he roared angrily, complaining, "Headmaster Dumbledore moved this painting here without saying a word?"

The stench spread through the corridor, and he realized it was the work of the twins as a prank, as he had smelled this smell many times before.

"Damn those Weasley twins! One of these days I'm going to hang them upside down from the ceiling by their ankles!"

He walked away cursing, apparently driven away by the mess on the floor and the stench in the corridor.

"It's okay, we're safe!"

Hearing Filch's heavy footsteps gradually fade away, the students breathed a sigh of relief and crawled out from under the tables.

Everyone had a relieved smile on their face, as if they had completed a project worth 100 million yuan together.

They all turned their eyes to Jian Yu at the same time, which made her suddenly have a bad premonition, and her sixth sense radar was beeping vigilantly.

Her premonition came true.

The students showed her a ferocious smile, pounced on her like hungry tigers, and instantly piled up a pyramid on her!

Jian Yu, who was pressed at the bottom, was in horrible pain. He felt that his internal organs were about to be squeezed out of his body and his soul almost left his body again.

After a difficult struggle, the Weasley twins finally succeeded in dragging her out from under the mountain of human flesh, with her almost foaming at the mouth.

But before she could catch her breath, she was greeted with another bear hug. Her classmates were all hugging and celebrating. Many of them were so excited that they burst into tears and danced.

They looked at each other and cheered:

“We are the winners!”

"We stood up to Filch!"

"We defended the club base!"

“This is the power of unity!”

Even Draco and Blaise had smiles on their faces. They were quite smug about their accomplishment in defending the base. The excitement and happiness brought by this incident even made Draco forget to continue mocking Harry and Ron.

"You must remember to cast an animal-repelling spell on the doors and walls here!" Draco said awkwardly, "I'm talking about you Weasleys, you stupid lions, don't you even remember that Filch has a cat?"

Fred and George rolled their eyes. The two brothers did not call Draco a jerk on the spot, which showed that they were in a good mood:

"Come on, Malfoy boy, don't make us beat you on a nice day -"

Fred whistled again to attract everyone's attention. He shouted:

"Hey! We have to retreat quickly, unless we want to be hung from the ceiling by Filch who comes back to clean up - what a thrill!"

George continued his brother's words:

"Wow, Fred, chains and handcuffs, I'm so excited to try them--"

Now no one dared to delay any further. They said goodbye to each other nervously and hurried back to the common room.

But everyone's mouth corners are harder to suppress than AK.

There were no casualties in this battle to defend the base, and the only person injured was Jian Yu.

She felt like she was injured internally.

Why couldn't Filch persist a little longer and discover the secret behind the portrait?

She thought dejectedly.

It’s not easy to drop out of school, Jian Yu sighed.

But fortunately, the professors and her guardians did not disappoint her expectations.

While the warriors were holding their first "Anti-Confiscation of Game Consoles" Congress, their deans were gathering in the principal's office to discuss the students' unusual behavior.
