A ruined Hogwarts

"...You stayed up most of the night. Don't tell me that you got lost in the castle until now..."

Professor McGonagall was wearing an orange nightgown, with a curling iron on her head, scolding two little Ravenclaw witches who had been caught by her.

"Who?" She suddenly looked towards the end of the corridor angrily and realized that someone had just ran past. As a witch with profound magical power, there is no way that a poor transformation spell could be hidden from her.

She picked up her wand and was about to catch the guy who was passing by grandly, but she saw a box with a red and black diamond pattern thrown from the other side of the corridor and landed not far from her.

This provocation made Professor McGonagall even angrier. As soon as she raised her wand, she saw a clown's head pop out from the top of the box, and then quickly expanded like a balloon, filling the entire corridor exit.

"Interesting little trick." Professor McGonagall's lips moved slightly, as if she slightly curved the corners of her lips, "But it's not up to par..."

She waved her wand, and the clown's head exploded with a "bang" in front of her.

With the sound of balloons exploding, countless balloons, flowers, ribbons and colored paper poured out, filling the entire corridor faster than before, engulfing Professor McGonagall and the three of them.

Professor McGonagall waved her magic wand, causing these colorful little things to separate into a passage, and led the two erring students out of the corridor calmly, but the guy who threw the box had already run away.

"Littering, I hope Mr. Filch can accept this little surprise." She glanced at the packed corridor and muttered in a not-so-bad mood.

After Owen ran out of Professor Maomao's territory, he couldn't help but look back and raised his hand to wipe away the non-existent cold sweat.

Oops, what a close call, I almost got caught.

"Owen, I wouldn't be surprised at all if we are expelled after tonight." Harry's voice was a little dazed.

"No, as long as you don't do anything too outrageous." Owen saw the restricted corridor from a distance, saw the white fax machine in the center of the corridor, and saw two little wizards who had already run to the fax machine.

"What's out of the ordinary?" Harry said weakly.

"Like flooding the entire castle with something." Owen said casually, throwing out the last box at hand.

The box hissed with brilliant red sparks, and flew into the corridor with a chirp, gradually turning into a swirling and gorgeous fireworks.

The fireworks caught up with the two little wizards in front of them in the blink of an eye. As if with infinite gravity, the two little wizards screamed and their bodies were involuntarily sucked to the tail of the fireworks, flying into the air as it danced. It whirled and spun like a big windmill.

"Ah--help!"

"Mom...wuwuwu..."

The screams of the two little wizards were drawn out, as long and weird as if the 0.5x speed was turned on. They followed the fireworks as they rushed away in the corridor, becoming part of the dazzling fireworks along the strange trajectory.

"Ah this..." Harry gasped.

"Don't worry, the fireworks will avoid all obstacles and they won't be hurt." Owen had already run into the corridor, with some joy in his tone, "Who wouldn't crave such a strange experience?"

I'm not eager at all... Harry said silently.

"Huh, I finally found you." Owen finally stopped in front of the fax machine and clenched his fists with a half-smile.

The Mantra Fax Machine is entirely white in color and looks like an ordinary Muggle fax machine, not bulky at all. A line of letters flashed on the small green screen: What's your question?

"Hurry...the professor is here!" Harry urged. He saw Professor Snape floating over quickly like a big black bat, followed hurriedly by Professor McGonagall.

"It's over. There is only one exit from this corridor..." He looked around and turned his attention to the locked door at the end of the corridor.

Owen raised his fist, stared at the fax machine with squinted eyes, and suddenly asked with a smile: "What is the exact value of pi?"

The flickering screen of the fax machine paused for a moment, and then countless pieces of white paper spewed out from the printing port, flooding the entire corridor in an instant like a tsunami of white paper.

Caught off guard, Owen and Harry, who were very close, were overwhelmed by endless white paper. The white paper filled the corridor like a wave and flowed out along the corridor. The professors who were rushing over had to stop and could only use magic spells to protect themselves and the students around them.

They looked at the white paper rushing past them, even Professor Snape and Professor McGonagall, their expressions were extremely blank for a moment. They have seen turbulent waves caused by magic spells, and they have also seen raging seas of fire, but this is the first time they have seen a white paper tsunami.

These white papers full of numbers are still pouring out endlessly, rushing towards corridors, classrooms and stairs. The little wizards who are curious and come to see the excitement never dream that one day they will I was almost buried alive in countless pieces of white paper.

"Who did it? Stop that thing!"

Owen was waving his wand among the piles of white paper, struggling to get close to the fax machine that was spitting out paper crazily. The spell separated the white paper around him, leaving him room to live. Harry no longer knew where he had been rushed, and he couldn't care about the poor guy for the time being.

He wanted to slap himself now. Why did he ask this question so suddenly? In other words, he was very surprised that the fax machine could answer this question. After all, according to his reasoning, the fax machine could only answer answers that others knew.

"No one can memorize so much pi..." Owen twitched the corner of his mouth and worked hard to move forward in the wave of blank paper.

The constant flow of white paper caused heavy resistance, making Owen's steps very slow. I don't know how long it took, but he finally came to the fax machine and slapped it hard.

The fax machine that was spitting out paper crazily suddenly stopped, then suddenly became illusory, and then disappeared silently. The raging wave of white paper finally stopped, making everyone sigh in relief.

At this time, the first to sixth floors of the castle were filled with white paper. They squeezed open the closed windows and fluttered on the grass outside the castle, like a heavy snowfall.

"Hurry up and get rid of these damn papers!" Professor McGonagall stumbled out of the pile of papers, waving her wand and using the vanishing spell, her face tense. The two little wizards beside her shivered with their shoulders hunched, as if they had turned into two little quails in the ice and snow.

Professor Snape was leaning against the wall and looking in the direction of the fax machine with a strange expression on his face. The corners of his eyes were twitching wildly, as if he didn't know what expression to make. Finally, he put on an unfathomable expression, waved his wand slightly, and a tornado rolled up the white paper and rushed out of the castle.

"Ah, what a disastrous day." Owen finally got out of the pile of paper and sighed as he looked at the ceiling close at hand.

"Look, I never dreamed that one day the castle would be flooded with white paper..." Harry also struggled to get his head out, rolling his eyes under the weight of the paper.

At this time, a rude and violent roar came from the end of the corridor, and the locked door was opened by a sea of ​​paper at some point.
