Sherlock was about to follow the Slytherin students back to the dormitory when Asinsha suddenly hurried over with Harry and Ron.

"Brother...... Wait a minute, brother, Hermione, Hermione! On the third floor, she didn't know about the trolls yet, and it was likely to be dangerous! Asinsha panted to Sherlock.

Sherlock glanced at the three of them, so if he wasn't here, the three little wizards would have secretly rescued Hermione.

"Who's going to care about that mudblood." Malfoy gloated.

Ron was furious, but unfortunately Harry didn't know what this meant, if he knew, he would probably move towards Malfoy with Ron, and Kirk frowned a little bit to hate the character of his apprentice, even Dandeni would not say such a thing.

"Shut up! Draco! Asinsha roared, she wouldn't allow Draco to insult her best friend with the word mudblood.

Draco closed his mouth, Sherlock frowned, and asked Dandney and Kirk and Lupo to take Draco and the first-year freshmen back first, they knew that this was Sherlock who had promised to rescue the little Gryffindor witch who didn't know it, and Femia leaned over and whispered to Sherlock, "You have to be careful, Mr. Sherlock, although the trolls can't hurt you, and Miss Asinsha, you should be careful." ”

Asinsha nodded, and Harry and Ron realized that Sherlock had always had a very beautiful female friend by his side.

"Okay, don't worry about Asinsha, I'll walk with you, Hermione's direction is very close to the basement where the troll is, and there is indeed a possibility of encountering a troll. Femia, I'll leave it to you. Sherlock decisively agreed to his sister's request, and then explained to a beautiful girl with blonde hair next to him, and Harry and Ron learned that the very beautiful Slytherin girl was called Fermia.

And Harry and Ron couldn't have imagined that Sherlock was so gentle and so talkative, maybe it was because the person asking for help was Sherlock's own sister Asinsha, or maybe the girl who was now threatened by the trolls was Hermione, the one who had been instructed by Sherlock in the library.

"Oh...... By the way, the two of them are Harry Potter and Ron Weasley, especially since both of them adore you, and they have asked me about your brother in the family. ”

"Hello Harry! And Ron, I have to say that both of you have excellent families! ”

Harry and Ron took a small step back, out of shyness, especially since this was the first time they had communicated with the legendary Prince of Spells, and hearing Sherlock boast about their families made Harry and Ron happy, but in reality they both knew that the so-called family was not worth mentioning compared to the rumored Mephisto family.

Harry and Ron tried to say something, but Sherlock walked towards the third floor with Asinsha, Harry, and Ron.

The four of them mingled in the Hufflepuff crowd and walked in the other direction.

They slipped quietly through the empty side hallway and hurried to the women's restroom.

As soon as he turned the corner, Harry sniffed, and a foul odor crept into his nostrils, the smell of a smelly sock mixed with a public toilet that was never cleaned.

Then they heard a muffled grunt and the sound of huge soles of feet dragging on the ground.

Ron noticed that at the end of one of the passages on the left, a behemoth was moving towards them.

They quickly retreated into the darkness and watched as it slowly walked into a patch of moonlight.

It was a horrible sight.

It was twelve feet tall, its skin dull and gray as granite, and its massive, dumb body resembled a huge pile of mud with a small head like a cocoa bean.

Its short legs are as thick as tree stumps, and underneath are flat, thick, calloused feet.

The smell emanating from it was disgusting.

It holds a thick wooden stick in its hand, which is dragged on the ground due to its long arms.

The appearance of the legendary troll is really peculiar enough, Sherlock laughed at the honest troll, the troll scratched his head, looked around, and saw that there was no one, so he stopped by a door and peeked inside.

It wiggled its long ears, made a decision with its small head, and then lowered its head and slowly slipped into the room.

Harry quickly stepped up and leaped, grabbed the key in his hand, slammed the door into it, and locked it securely.

"It's done!" Looking at the door that had been shut down by Success, Harry smirked at Sherlock and Asinsha.

Just as the four of them were about to return, a terrible, frightened voice came from the room.

"Oh, oops." Ron said, his face pale as the ghost of Baro the Bloody.

"That's the women's restroom!" Harry couldn't even breathe.

Asinsha's heart was nervous, as she could hear the voice of her best friend Hermione, and she looked at her brother Sherlock, who had already drawn his wand.

"Stop talking nonsense." Sherlock waved his wand and blew the door open without a spell, Harry and Ron were stunned, but Asinsha urged the two of them to hurry in, and the four of them rushed in, Hermione Granger cowered on the opposite wall, as if she might faint at any moment.

The troll was closing in on her, smashing the pool off the wall as it walked.

Harry and Ron both looked at Sherlock at a loss, Sherlock calmly looked at the troll less than three meters away from Hermione, a red light was generated in front of the golden wand, flying towards the troll, the ball of light seemed to contain a ball of high temperature, some parts of the body of the troll hit by the ball of light were instantly scalded by the heat, the troll howled for a lifetime, but the ball of light did not stop, but continued to spread in the part of the hit, the feeling of the troll was like being thrown into a boiling soup pot, It's like a snail that has been trampled to pieces in the sun......

The troll wailed and rushed out, the heat continued, as if the troll's body was burning, and a cloud of gray-black steam came out of the troll's mouth, nose, ears, and eyes, and every pustule on the troll's body burst open and emitted steam, as did the pores.

The floor of the women's toilet made a loud vibration, and the wind pressure brought by the huge body of the troll made Harry and Ron squint their eyes, and the stench of steam was particularly pungent and unpleasant, like the smell of water evaporating from the underground stinking ditch due to the temperature of the sun.

The next moment, their eyes narrowed slightly, and they saw an incredible scene, the trolls kept rushing left and right, but Sherlock pulled Hermione over with a wave of his wand, and there was a rippling barrier in front of them, like a calm erected lake, and every time the troll collided with it, it would form a ripple, but it could not be broken.

In the end, the troll lost its strength, and fell to the ground very miserably, causing a shock, almost half of the room was destroyed, Harry and Ron opened their mouths in a daze, Asinsha turned her head in disgust, Hermione also stopped sobbing, and for a while, the atmosphere in the room was a little eerily quiet.

In addition to the foul smell, and the corpse without a trace of moisture, it has become a giant dried corpse of the troll.
