William took out his wand and first released a bubble head spell on himself, but there was no way, the smell was too bad.

Can't you give it a bath Quirrell!

After putting on the bubble head charm, William felt that the smell in the air was a little smaller, but it was still disgusting, and he despised Quirrell's irresponsibility, and then added a phantom charm to himself.

Don't forget, there's Quirrell next to him, who controls the troll, and I don't know how he and the owner of the lump behind his head endure the stench.

Maybe it's because Voldemort doesn't have a nose, William guessed maliciously.

Despite his disdain, William was fully prepared, and he waited for the footsteps to fade away. Calculating the time, Quirrell should have gone to the Great Hall, and William slowly felt towards the outside of the classroom.

As soon as he arrived in the corridor, the smell in the air became even stronger, and William did not stop, and walked directly towards the women's toilet on the first floor.

As early as daytime, William had already stepped on a good point, so he was moving very quickly at this time.

Soon, William found the location of the troll, and at this moment it was carrying a large wooden stick, and its big feet were wandering aimlessly on the first floor.

However, he did not take immediate action, but waited quietly on the sidelines.

，，，，，，，，，，，，，，，，，，，，

Inside the Great Hall, Harry and Ron were looking at tonight's unique Great Hall with obsessive expressions.

Thousands of bats fluttered across the ceiling, and thousands of dark clouds swirled and fluttered above the plates.

On top of that, there are glowing pumpkin heads piled up all around, and from time to time, some sparks will splash out of them, transforming into four creatures that symbolize the four houses of Hogwarts.

Even the lamp holder is pumpkin-shaped, and the festive atmosphere can be said to be quite strong.

If William was here, he would have been very familiar with this scene.

Presumably, Professor McGonagall borrowed William's ideas, but the professor's spellcasting was naturally much better than William's.

William can only turn Mars into a ribbon, while Professor McGonagall can turn it into a complex creature and even make it do some movements.

Harry noticed that not far away, a spark from a pumpkin's head had turned into a mighty lion, and it looked up as if it were roaring. It's magic!

Harry thought it was the best holiday he'd had in eleven years.

Ron on the side also showed a foolish smile.

Originally, on the way to the banquet, Harry and Ron were a little uneasy because of William's words.

Plus overhear Hermione's roommate Patil saying to her friend Lavender that Hermione was crying sadly in the women's restroom.

This made Ron even more upset, the boy's heart is not bad, he just loves to save face, and he is stubborn and refuses to apologize first.

However, when Ron saw the colorful ornaments, and the food on the plate that was as rich as the opening feast, the little uneasiness and apology for Hermione was immediately thrown out of the clouds.

Hermione? I'm sorry, but who is she? Ron picked up a chicken leg and thought as he nibbled on it.

Just as the wizards in the auditorium were talking and laughing and eating, there was a bang, and the door of the auditorium was slammed open, and Professor Quirrell rushed in.

He walked briskly over to Dumbledore's chair, his face full of horror.

This ghostly appearance made the atmosphere in the hall quiet, and countless eyes fell on Professor Quirrell, which seemed to make him even more nervous, because his stuttering was much worse than usual.

He gasped and said, "Giant, giant, troll in the underground classroom, I, I, I thought you should know." ”

With that, he fell straight forward and fell to the ground, unconscious. Only Professor Dumbledore was left with a scarf covering the back of his head.

The Great Hall was silent for a few seconds, for what Professor Quirrell said was so appalling that the young wizards hadn't reacted yet.

Then, with an uproar, the hall seemed to explode, and the little wizards looked around in a panic, as if a troll that had been four meters tall would rush into the hall in the next second.

Dumbledore stood up, pulled out his wand and unleashed several piercing explosions, several fireworks exploding on the ceiling above the Great Hall.

This made the little wizards below quiet

"Silence! No one can hurt you at Hogwarts. ”

Dumbledore said in a low voice, it could be seen that he was very angry, the headmaster obviously didn't expect Quirrell to play such a trick, but he couldn't expose him in public.

"Prefect! Take the students from your house back to the dormitory! The following order made everyone find the backbone.

The prefects of the various academies stood up one after another, leading the students of their own academies.

"It's broken! Hermione! ”

"What's wrong with her?"

"No one told her about trolls!"

By this time, Ron, who had put down the chicken legs, finally remembered Hermione. He and Harry looked at each other several times, and eventually, the boy bit his lip,

"Let's go, let's go find her, and be careful not to let Percy see it."

They followed the Hufflepuff students through the empty hallway and headed for the women's restroom.

，，，，，，，，，，，，，，，，，，，，

William felt that he was about to be stunted, and the smell was still very domineering even after being filtered by the bubble head charm.

Why didn't it go to the women's restroom! William looked at the troll in front of him and suddenly felt that he had made an extremely stupid decision.

Fortunately, as if hearing something, the troll lifted its little head. I listened carefully, and then finally walked in the direction of the women's bathroom.

William hurriedly followed, and soon spotted Harry and Ron trotting from the other side of the hallway.

Under the effect of the illusion spell, the two of them did not notice William's existence,

"Merlin is on top! What the hell is this! ”

William heard Ron's whispers, apparently the two of them spotting the troll walking towards the women's restroom.

Then, after witnessing Harry and Ron's godly operation of locking the troll in the women's bathroom, William couldn't hold back anymore when he heard Hermione's hoarse screams.

He rushed over, pushing Harry and Ron out of the way, and then a shock spell pushed the door open, and now William was becoming more and more comfortable with the impact charm since learning a lot of spell-casting techniques from Professor Flitwick.

William rushed into the women's restroom and saw Hermione, who had been cornered by the troll, the girl was in a bad state and seemed to faint at any moment.

William didn't have time to think about it, he swung his wand and blasted the opposite wall to pieces with a blast charm, and the loud sound managed to attract the troll's attention.

While the troll was confused, William quickly used his magic knot to form a rope to grab Hermione, pick up the girl, and protect her behind him.

It was then that the troll's little eyes finally spotted William, and it roared.

William looked up at the hill-like troll in front of him without fear, and he clutched his wand tightly.

Come on, let me see what you can do!
