Harry Potter and the Cataclysm

Carnie stared at the cloth-covered object, repeatedly telling himself that he shouldn't linger here. The whole situation felt off, unsettling even. It was best to find another classroom.

Yet, his feet refused to move. His eyes remained locked on the covered item.

"Just one peek. Just a quick look, and then I'll leave!" He convinced himself as he hesitantly stepped forward. After all, this school was full of secrets, and sometimes, all it took was a little luck and a bit of courage to uncover them.

"Forget it! Curiosity killed the cat, and I prefer staying alive!" Snapping back to his senses, he quickly turned toward the door.

But then another thought struck him—If I don't look now, won't I regret it years later?

Without realizing it, he had already turned back toward the object.

"This thing is locked up here. I can always come back tomorrow with Harry and the others. It's not like I won't get another chance." Shaking his head, he firmly walked toward the door.

But just as he reached for the handle, he spun around and dashed back inside, carefully closing the door behind him.

It was Filch.

It was already past curfew—if he got caught, it would be a disaster.

"Looks like fate has decided for me," Carnie thought. "Might as well use this time productively."

Of course, that didn't mean he was about to yank the cloth off the mysterious object. That thing was way too suspicious—no need to be reckless.

"Aguamenti!"

A small stream of water appeared in the air, which Carnie carefully shaped into a sphere the size of a human head.

It was time to test a theory.

Earlier in the afternoon, he had seen water turn to ice instantly, which made him reconsider his previous assumptions.

Thinking of water as countless individual molecules, he realized that they didn't naturally bind to each other, which was why water had no fixed shape. Previously, he had only manipulated its external structure, forcing it into forms, but now… he wanted to go deeper.

His eyes flickered, and his amber irises shifted into a sharp, emerald green.

A surge of clarity swept through his vision.

This ability, which he called infusing sight, was something he had accidentally developed during a morning training session. One day, while circulating his inner energy (Qi), a sudden burst had entered his eyes. The result? He could see the sun more clearly than ever before.

That gave him an idea.

What if he refined his eyes with Qi every day? Would that eventually awaken some kind of inner sight?

To his surprise, it worked.

Later, when he added magic into the mix, his eye color had completely transformed. But the pain—dear Merlin, the pain had been unbearable. For hours, it felt as if his eyes were being burned out of their sockets. He had almost thought he was going blind.

Still, the end result was fascinating.

With this sight, he could see molecular structures clearly.

The only downside? It was incredibly draining. His magic would deplete rapidly whenever he used it, though his Qi reserves remained unaffected.

Focusing on the floating water sphere, he tried something new.

He willed each individual molecule to link together, forming a tightly connected structure.

Slowly, the surface of the water ball stopped rippling. It became completely still—its transparency turning crystalline, like a perfect, polished gem.

Carnie withdrew his control and caught the sphere in his hands.

"Huh? It's not cold?" He squeezed it—rock solid.

Dropping it onto the ground, he heard a dull thud—it didn't shatter. It simply chipped at the edges.

"Not bad."

To test its durability further, he threw it against the stone wall.

CRACK!

The sphere finally broke apart, splitting into several large, jagged fragments. Even those fragments didn't immediately turn back into water.

"So, it's half a success?" He mused, picking up a shard.

It had the hardness of ice but lacked its cold temperature.

"I changed its molecular structure… could I take this a step further?"

He thought of graphite and diamonds—both composed of carbon, yet vastly different due to their atomic arrangements. If he could manipulate water molecules similarly, could he make something as strong as diamond?

"Aguamenti!" Another water sphere formed.

This time, he focused on compacting its molecular structure into a diamond-like lattice.

The sphere shrank.

What had once been the size of a human head was now reduced to a mere ping-pong ball.

Lifting it, he weighed it in his palm. The density was striking—it felt as though he was holding a lump of metal.

Taking a stance, he threw it at the wall with full force.

THUD!

The ball bounced off the wall and rolled to the floor, completely unscathed.

The wall, however, had a noticeable dent.

Carnie's eyes gleamed. This is it.

"If I refine this process and speed it up, I could make an entire set of crystal armor on the fly."

His mind raced with possibilities.

But then—he realized something.

"What about magical resistance?"

He set the sphere down.

And then... he hit a roadblock.

"Wait a second… I don't actually know any offensive magic."

Stunning Spell? Nope, it only worked on living things.

Petrificus Totalus? Same problem.

He sighed. Alright, let's move on to something else.

BAM! BAM! BAM!

One after another, he conjured new objects.

An icy arrow like Ashe's. A Demacian greatsword. A knight's shield. A long spear. Even a motorcycle helmet.

"Damn, this is cool." He admired his work.

They were all transparent, like glass. Maybe he could find a way to color them later.

"Heh… magic crystal arrows!" He tossed one experimentally.

"Demacia!" He planted the sword into the ground dramatically.

"This is definitely blackened King Arthur aesthetics!" He grabbed the shield, then switched to the spear.

"A single glimmer of light, and then—" He thrust the spear forward. "The dragon roars to life!"

This was insane. He had just given himself a weapon system.

He had to show this to Harry and Ron.

"I need to get my hands on some swordsmanship manuals. My dream of becoming a warrior isn't over yet."

Then a thought struck him.

"Wait… if I can channel Qi into these weapons, can I also infuse them with magic? Like—actual magic?"

He conjured another crystal sword.

Gripping it tightly, he circulated his Qi.

Immediately, the blade pulsed with white energy.

Taking a step forward, he swung.

The blade didn't touch the wall.

Yet—

SWOOSH!

A deep, horizontal cut appeared, slicing into the stone by at least four inches.

Carnie stared, wide-eyed.

"Oh shit."

His hand trembled slightly as he reached out, tracing the cut with his fingers. It was clean—precise.

"Sword Qi…?"

He barely had time to process before another idea hit him.

"What about magic?"

He switched gears, pouring his magic into the sword instead.

This time, the blade glowed—a brilliant, almost blinding blue.

With a powerful slash, he released the energy.

BOOM!

A massive blue arc exploded forward, smashing into the wall.

Dust and debris went flying.

When the dust settled, a three-meter-long gash marred the stone.

Carnie gawked.

"Holy sh—"

Panicking, he yanked out his wand.

"Reparo! Reparo! Reparo!"

He frantically repaired the damage, sweating bullets.

Did Filch hear that?!

Pressing his ear against the door, he listened.

Silence.

He let out a breath of relief.

"Okay. That was reckless."

But his mind was already buzzing with new insights.

His infusing sight only worked on things he created.

He couldn't see through ordinary objects.

It meant that this ability wasn't true molecular vision—it was creator's vision.

Still, that was insanely powerful.

Carnie turned back to his sword, now faintly tinged with blue.

"Elemental attributes…?"

Could he incorporate fire? Lightning?

His excitement grew.

"I need to get my hands on some combat techniques."

Just as he was about to sit down and restore his energy—

"Ah!"

His body tensed.

In a flash, he grabbed his sword and pointed it toward the shadows in the corner of the room.

Someone—or something—was there.
