The Troll
The scene inside the toilet was terrifying: a hideous creature, at least four meters tall, stood right in the middle.
The creature's skin was dull and gray, like granite, and its huge, clumsy body resembled a massive pile of pebbles, topped with a small head the size of a cocoa bean.
Its short legs were as thick as tree stumps, and below them were flat, rough, calloused feet. The odor emanating from its body was nauseating.
--Troll!
Troll are magical creatures with incredible strength but very low intelligence.
Even with their low intelligence, they are still creatures with a Ministry of Magic level as high as XXXX.
Other Magical Creatures of similar caliber include the Thunderbird and the Tebo.
In other words, the Troll is extremely dangerous and definitely not something a young wizard can handle.
Hermione was crouching in the corner on the other side, trembling.
"Come here right now, you ugly thing!" Harry grabbed some pebbles from the ground and threw them at the Troll.
In fact, he didn't need to smash the Troll; the loud noise was enough to attract it.
The loud noise shook his head, the explosion making his already fuzzy mind even more confused.
It hesitated for a moment, then roared and walked towards William and his companions, raising the wooden stick in its hand.
"Come here, run, run, Hermione!" Ron looked at the Troll with some fear, but still tried his best to shout.
The girl seemed paralyzed with fear; she sat on the ground, unable to move her legs, her mouth agape in terror.
I was crying peacefully in the bathroom when suddenly a Troll appeared behind me. Anyone would be terrified.
"Impedimenta!" William swung his wand rapidly.
Several invisible walls surrounded the Troll, preventing it from moving any further.
The Troll kept crashing into the invisible wall, but William didn't even look at it. He walked forward with his wand in hand, straight up to Hermione.
William crouched down and reached out to examine the girl's body. He found no external injuries, only that she was extremely frightened.
As William moved, Hermione finally came to her senses, and a glimmer of light gradually returned to her eyes.
The girl looked at William, then suddenly choked up slightly, her eyes red from crying.
William reached out and wiped the tears from Hermione's cheek, then took out a chocolate from his pocket and said softly, "Eat it, it'll make you feel better."
Hermione nodded blankly, murmured an "Mmm" through a sob, and took the chocolate.
William turned to look at the Troll, wand in his right hand, a gentle breeze ruffling his hair.
William frowned. How could Troll appear at Hogwarts? This was completely illogical. The probability of it getting lost and entering the school was even lower than the probability of Death Eaters invading Hogwarts.
However, William had no time to think further; the trapped Troll had already begun to go berserk.
It roared, swung its hands, and sent the wooden stick spinning off its shoulders and crashing forward into the invisible wall with a deafening roar.
The Troll stomped its right foot on the ground, creating a large crater and kicking up a cloud of dust. It then gripped one end of the stick again and slammed it into the ground.
The troll's Troll strength was fully revealed; it actually pried a large slab of thick marble flooring off the ground and smashed it in all directions.
"Impedimenta" began to shake violently.
The Troll may not be very intelligent, but having lived in the Forbidden Forest for so long, even without wisdom, its brute strength alone makes it impossible to be trapped by ordinary magic.
The wooden stick, made of some unknown material, did not shatter on the spot. Instead, the Troll bent it with both hands, creating a slight arc. It then leaped up and struck the invisible barrier.
The "Impedimenta" were finally smashed to pieces by the Troll's brute force!
The Troll went completely berserk, displaying its savagery. Like the Green Giant, it relentlessly pounded everything it could reach.
Enveloped in unparalleled power, dense patterns, resembling a spider web, formed around the Troll.
But William isn't Loki; he's a wizard, yet he's wielding a dagger and acting as a melee mage.
He waved his wand again, and all the water pipes in the toilet burst, sending jets of water shooting high into the air.
William murmured, "Rain Curtain Condensation!"
The water columns swirled everywhere, but this time they didn't form a giant Rain Tornado. Instead, they condensed into a faint silver line, slicing towards the Troll.
If you look closely, those silver threads are made up of countless tiny daggers formed from water, and they are imbued with magic.
Troll are thick-skinned and possess an innate ability that allows them to resist a lot of magic, but their necks and skulls are their weakest points.
William turned his head slightly and whispered to the girl behind him, "Don't be afraid, close your eyes!"
Hermione quickly closed her eyes.
The silver line, twisted by magic like a tangible blade, easily sliced through the Troll, and its small head Descendo with a thud.
The dagger pierced the Troll.
No matter how tough the Troll is, it can't withstand hundreds or thousands of daggers.
Everything seemed to freeze. Then, a hissing sound came from the toilet as green blood splattered all over the walls and splashed onto Harry Ron's face as he stood frozen in the doorway.
The two of them stared wide-eyed and gasped for breath, like salted fish that had fallen onto the beach.
William's wand spun again, and the silver threads shattered instantly, forming raindrops the size of soybeans that fell on the walls on both sides, creating countless tiny craters.
William was extremely satisfied. Although this magic was a combination of Transfiguration and spells, the real inspiration came from water cutting.
The principle of waterjet cutting is that water jets under high pressure generate velocity, forming ultra-high-speed "water jets".
The spell "Rain Curtain Condensation" not only has speed, but also the power to Transfiguration into daggers and spells.
At least when dealing with Magical Creatures, it's more effective than "Stupefy".
All I can say is that if you master math and physics, you can go anywhere in the world without fear.
As the Troll fell to the ground, loud footsteps suddenly came from afar. Professor McGonagall rushed into the room, followed closely by Snape, with Quirrell bringing up the rear.
Quirrell glanced at the Troll before letting out a weak sob, sitting down on the ground and clutching his chest.
Snape bent down to look at Troll Troll, examining the smooth wound on its head.
He frowned. In terms of effectiveness, this magic was not much less lethal than his own "Sectumsempra".
However, Sectumsempra is Dark Magic, while the spell William used did not have the effects of Dark Magic and was more inclined to be superimposed.
By combining countless small attacks at a single point, a destructive effect can be achieved.
But logically speaking, water shouldn't have such great power, right?
He gave William a deep look, filled with doubt. Even more doubtful was whether this kid really wouldn't become the third Dark Lord.
He glanced at Quirrell out of the corner of his eye, Quirrell was slumped on the ground clutching his chest, as if to say, "Baby's scared!"
Snape suppressed his anger and disgust, wishing he could curse Quirrell.
His thigh was aching again.
Damn it, I've been tricked!
