Hogwarts Kryptonian

Lu Yunkai and Harry Ron trotted all the way to the door of the girls' bathroom in the corner of the second floor.

In the distance, Hermione's scream could be heard coming from inside, and the bathroom door had been smashed into pieces. The three of them rushed in without having time to think carefully.

Although Lu Yunkai had already made mental preparations after listening to Daphne's words, the scene in the bathroom still made his heart skip a beat.

Hermione huddled in the corner of the bathroom, curled up into a ball. The sink in front of her had been smashed, and the water in the pipe was spraying out. Between the three of them and Hermione, A giant who was more than three meters tall was standing there, holding a thick-headed wooden stick more than one meter long in his hand.

"Hermione, it's okay, we are here, don't be afraid." Lu Yunkai took a deep breath and said to the screaming Hermione in as calm a voice as possible.

"...Okay." Hermione nodded with a cry.

"Hey! Big fool!!" Ron picked up a stone broken by the mountain monster from the ground and threw it towards it.

It was hitting the guy's abnormally small head compared to his body.

The mountain monster stretched out his hand to rub his head a little stupidly. He turned around and saw the three boys behind him. He raised the wooden stick in his hand and swiped at the three of them.

"Get down!" Lu Yunkai shouted to Harry and Ron.

But, it seems a bit redundant.

Ron's reaction was much faster than his. Before he could say anything, he had already leaned forward and his whole body was directly on the ground.

But Harry seemed a little dazed and couldn't avoid it in time.

Fortunately, he was standing relatively outside, and although the mountain monster seemed to be very powerful, its movements were too slow. Although the huge wooden stick was brought to Harry, it did not directly knock him away.

Harry also reacted and directly hugged the wooden stick that was hit and hung on it.

Then the whole person was lifted up by the mountain monster with the stick.

The mountain monster also realized that there was someone hanging on his weapon, and he swung the wooden stick around in an attempt to throw Harry off.

"Harry! Hold on tight! Don't panic, this guy is out of his mind!"

Lu Yunkai reminded Harry loudly, but he still lost his sense of proportion.

In two lifetimes combined, he could count the number of fights he had fought on one hand. He really didn't know what he could do at this time.

"Use your wands!! Wands!!"

Hermione, who was squatting in the corner, became the calmest one at this time.

"Oh yes!"

Lu Yunkai took out his wand from his robe.

"Petrify them all!!" Lu Yunkai waved the magic wand in his hand and used the petrification spell on the mountain monster.

A ray of golden light flew from his wand towards the mountain monster, but was deflected after contacting its skin and reflected to the ground.

Only then did he remember that Daphne said that mountain monsters are not afraid of magic!

Lu Yunkai didn't have time to regret.

The mountain monster was hurt by his magic attack, let out a howl, raised the wooden stick high, and seemed to bring Harry with it to hit Lu Yunkai.

"Harry! Let go of the stick!" Ron, who was lying on the ground, shouted quickly.

Harry, who was hanging on the wooden stick, immediately followed suit, broke away from the wooden stick and landed on the mountain monster's neck.

"Hold on! Don't fall!" Hermione shouted from behind the mountain monster.

"I'll try my best!!" Riding on the mountain monster's head and neck, Harry held the mountain monster's ears tightly with both hands and pinched its nostrils.

The wooden stick in the mountain monster's hand had already hit Lu Yunkai.

"Yingardium Leviosa!" Lu Yunkai looked at the weapon coming toward him, waved his wand, and used the levitating spell on the wooden stick.

Mountain monsters are immune to magic, but your weapons can't be immune to magic, right?

However.

"No! Not only do you have to wave it, but you also have to click it! It's broken!!"

Hermione, who was hiding in the corner, discovered Lu Yunkai's mistake in casting the spell.

Things were indeed as Hermione expected. The levitation spell did not work, and the huge wooden stick still fell down.

As Lu Yunkai's spell failed to release, not only Hermione, but also Ron and Harry instinctively closed their eyes.

The wooden stick, which probably weighed several hundred kilograms, hit Lu Yunkai so hard that no one thought he had a chance of surviving.

Except Lu Yunkai himself.

When the spell failed to be released, he was stunned for a moment, but soon he had an alternative plan.

If the spell is unreliable, then rely on the system!

He took a deep breath and clasped his hands in front of him.

Quiet.

The mountain monster was stunned.

The huge wooden stick in its hand disappeared.

"If you are not afraid of magic, I don't believe you are not afraid of potions!"

Lu Yunkai roared angrily and threw a medicine bottle towards the foot of the mountain monster.

There was a crisp sound of the potion bottle breaking, and the black liquid inside flowed out, touched the body of the mountain monster, and immediately turned into a puff of black smoke.

With a loud bang, black smoke completely enveloped the mountain monster.

A heart-stopping scream came from the black smoke, and then, with a thud, the huge mountain monster fell.

When the thick smoke dissipated, there was a pool of black and sticky liquid like asphalt on the ground, and the mountain monster lay there not knowing whether it was alive or dead. Only half of its two legs were left, and a leg bone was soaked in the black liquid.

The scene was extremely tragic and terrifying.

Harry, who was riding on its neck, fell down together and rolled several times on the ground before stopping.

"Harry, are you okay?" Lu Yunkai was shocked when he saw the scene he had created, but he still tried to stay calm.

"I'm fine... Yun Kai, what's going on?" Harry, who got up from the ground, looked at the miserable state of the mountain monster that was so arrogant just a second ago, and he stuttered out of fear.

"Explosive corrosive agent." Lu Yunkai said his name calmly.

One hundred and twenty gold galleons. What a huge loss this time! He said silently in his heart.

When Lu Yunkai realized that he had failed to cast the floating spell, his first reaction was to activate the system, put his hands in front of him, and then sold the wooden stick the moment it touched his body.

Three Nats.

The only thing that can comfort Lu Yunkai is that the system determined that the stick was an ownerless thing and the sale went smoothly, otherwise Lu Yunkai would have been a pile of meat...

"I'm not talking about that, I'm talking about where are its weapons?" Harry asked.

"I have an amulet that can protect me from disaster." Lu Yunkai thought of Malfoy's pendant before, made a fool of himself, and then shouted to Hermione: "Come here! Be careful not to touch the black water on the ground. "

"Okay." Hermione nodded, first picked up the wand she had dropped in the far corner, then jumped over the black water lightly and came to Harry and Ron.

But he seemed to be avoiding Lu Yunkai intentionally.

Obviously, the tragic situation of the mountain monster on the ground left her with lingering fears.

"Ron, don't you want to apologize to Hermione?" Lu Yunkai reminded Ron.

"Oh, I'm sorry, Hermione, I didn't mean what I said, I..."

"If you hadn't attracted its attention just now, I would have died in its hands." Hermione interrupted Ron, "By the way, Lu Yunkai, why are you here?"

"...Can't I treat you as a friend? Am I not worthy?" Lu Yunkai smiled speechlessly.

This girl really can’t speak!

"That's not what I meant!" Hermione waved her hands quickly.

"Oh, I'm kidding you!" Lu Yunkai still smiled and shook his head, "I came here because I was worried that Harry and Ron would be in danger as the two of us."

"No matter what, thank you." Hermione nodded seriously to Lu Yunkai.

"You guys! Why are you here!!"

At this moment, Professor McGonagall's voice sounded.

A group of people appeared from behind a few people.

Lu Yunkai glanced at the group of people who were coming, "Hey guys, basically all the staff of the entire Hogwarts school are here!"

Except Snape and Quirrell.

Why aren't they there?

"You..." Professor McGonagall's tone was filled with anger, but looking at the mountain monster lying on the ground, she was speechless for a moment.

"Did you get rid of the mountain monster?" Dumbledore walked out of the crowd and asked Lu Yunkai, who was standing in front of the crowd.

"Yes, is us……"

"That's right, Professor." Hermione, who was blocked by Lu Yunkai, stood up. "After hearing the news about the mountain monster, I thought I could get rid of it, so I ran out regardless of Harry and Ron's obstruction. People, and Lu Yunkai followed because they were worried about me. As a result, I was almost killed by the mountain monster. Thanks to the three of them, especially Lu Yunkai, they used some kind of magic potion to kill the mountain monster."

"...Well, explosive corrosive potion." Dumbledore glanced at the black liquid underground, "Severus taught a good student!"

"But it's too dangerous for you guys to act without authorization! The mountain monster is no joke." Professor McGonagall still had a cold face, "Because of your recklessness, your college will lose points because of you."

"This..." Lu Yunkai scratched his head in embarrassment.

In order to save three Gryffindor students, I caused Slytherin to lose points in the House Cup. Isn't he afraid that he will be punished by Professor Snape and scolded by the Slytherin students when he returns? ?

"You all go back to the lounge." Professor McGonagall glanced at the group of people coldly.

"……yes."

The four of them looked at each other, lowered their heads one by one, and fled the bathroom in despair.

****

"Your Excellency, Principal, do you think this explosive corrosive potion was refined by Lu Yunkai himself?" Professor McGonagall looked at the back of Lu Yunkai and others leaving, and said with some worry, "He is only in the first grade this year! This potion is very It’s dangerous!”

"No one even sells this potion in Knockturn Alley. If he didn't refine it himself, where else could it come from?" Dumbledore shook his head, "It seems that Severus cultivated this potion. The genius is a little too much!”

"..." Professor McGonagall looked ridiculous.

"Okay, let's clean up this place, and you can go back to your respective colleges to settle the students."

"yes."
