I was inventing at Hogwarts

The monster was twelve feet tall, with skin as dull as granite.

The huge and stupid body is like a huge pile of smelly mud, with a small head like a coffee bean on top.

Its short legs are as thick as tree stumps, and beneath them are large, flat, thick, calloused feet.

The smell emanating from him was disgusting.

The troll walked forward slowly, holding a thick wooden stick in its hand.

Because of its long arms, the stick dragged along the ground.

As he continued to advance, he made a clicking sound.

Finally, he stopped by an undecorated door and peeked inside.

It swung its long ears and stood in a daze for a while, and finally chose to enter that room.

"The key is in the keyhole. It may have been left by Filch."

Harry saw the small key at a glance.

"We can lock it inside to prevent him from running around and hurting Hermione." Rigg thought for a while and said.

"Good idea," Ron said nervously.

There is nothing better than preventing danger before it happens.

Presumably in the original book, Harry and the others just failed to lock up the troll.

Rigg thought to himself.

The trio tiptoed and sidled slowly toward the open door without making a sound.

Rigg observed the troll's movements keenly.

While the troll didn't look back.

It's now!

Rigg suddenly jumped forward and grabbed the key in his hand.

With a bang, the door was slammed hard by Rigg.

Harry and Ron immediately blocked the door left and right to prevent the troll from escaping again before locking the door.

Li Ge, who was locking the door, was amused.

With a body as small as the brothers, Ron couldn't even run a thousand meters without throwing up, and he was still fending off a troll.

Cutely silly.

"It's done!"

The door was successfully locked, and the troll didn't seem to react yet, and there was no sound of banging on the door.

The trio were so excited about their success that they high-fived each other and started running back down the aisle.

While running, he yelled Hermione's name, telling her that the troll was on this floor and to come out quickly.

However, as soon as they reached the corner, they heard a sound that almost made their hearts stop beating.

A frightened yet familiar female voice.

It was coming from the room they had just locked.

"Oh, crap," said Ron, looking as pale as the ghost of Bloody Balor.

"That's the women's room!" Rigg exclaimed.

Because this women's restroom is being renovated, there is no signage and no students will come.

That's why Hermione came here and allowed herself to break down for a moment.

It won't be discovered anyway.

Merlin's socks, Hermione wouldn't be harmed by his butterfly effect.

This was the first time that Rigg couldn't hold the wand in his hand, and his hands were shaking.

"Hermione is in there!" The three people looked at each other and said at the same time.

They really don't want to go back and face the trolls again, but what other choice do they have?

Rigg suddenly turned around and ran back to the door.

He turned the key with trembling hands, clumsy from nervousness.

The lock is unlocked.

Harry opened the door, and Rigg and Ron rushed in.

This is a girls' bathroom that has not yet been renovated.

It is as big as half a classroom, and there are many devices waiting to be installed and decoration debris piled on the floor.

The pool was the first part to be installed, and it was placed in a row. It can be seen that it will be used by girls who attend classes on this floor.

Hermione Granger huddled in the opposite corner, shivering.

Her face was paler than Malfoy's, and her lips were bloodless.

The troll didn't see her, and might have been distracted by the trio's excited shouts.

The troll slowly turned his head, looked into the room, and chose a random direction to move forward.

But this direction is approaching Hermione.

Trolls are really stupid.

It did not avoid obstacles when it saw them, and crashed into countless pools of water along the way.

Feeling the slight pain, the troll spun around in circles and roared.

Looking for that non-existent opponent.

Finally, its little eyes slowly focused on Hermione.

"The troll is stupid, try to confuse it!"

Rigg shouted anxiously, pulling out his wand.

Countless debris from the bathroom floated up, clattering against the troll and the wall next to him.

Debris fell to the ground, making a loud noise.

The pile of debris hitting the body also made it feel a little uncomfortable.

The troll stopped a few steps away from Hermione.

It turned around awkwardly and blinked its little eyes stupidly, trying to see what the sound was coming from.

Its ugly little eyes saw Ron.

But no attention was paid to Rigg and Harry.

It hesitated.

Then he strode towards Ron, raising the wooden stick in his hand to hit him.

"Hey, you idiot!"

Ron shouted courageously at the troll, then turned and ran away.

While running, he tried to pull out the wand tied to his waist.

It's just that I may have eaten too much, and my round belly didn't leave room for the wand, so I couldn't draw it out no matter what.

Harry also came in at this moment, picked up a metal pipe on the ground and threw it at the troll.

"Ugly, look at me!"

The troll didn't seem to notice that the metal pipe hit its shoulder, but it heard Harry's strange scream when he exerted force.

Then he stopped again and turned his ugly big nose towards Harry.

Rigg took this opportunity to go behind it and next to Hermione.

"Get up quickly and find a chance to run out!"

But Hermione's legs might have weakened due to fear. She tried to stand up a few times and squatted down again, only to look at the troll not far away in horror.

There was no time for Hermione to recover.

Rigg grabbed Hermione and held her against him.

Fortunately, he is developing well, otherwise he would not be able to lift the little wizard who weighs dozens of pounds.

Harry and Ron could only stall for time, running back and forth to distract the troll.

Annoyed by the troll flying the kite back and forth, he roared and rushed towards Harry who had just yelled.

Seeing this, Ron unconsciously ran a few steps forward to rescue Harry, but was forced back by the giant stick wielded by the troll.

Hermione was petrified by the situation before her, completely limp and leaning against Rigg.

Tears gradually filled her eyes, and she regretted why she came out alone today.

Also dragging down Rigg, Harry and Ron.

Ron drew his wand.

Then I heard Rigg shouting, "Let's cast the floating spell on the stick together!"

Ron had never learned the levitation spell, but now, he suddenly remembered Hermione's words.

Harry is indeed very courageous, and the Sorting Hat made the right choice.

Facing the charging troll, Harry did not flinch and raised his wand.

Hermione seemed to have finally come out of her trance, looking at Rigg, Harry and Ron who were desperately trying to save her, and shouted with a tearful voice.

The shouts of four people converged into a spell.

"Wingardim Leviosa!"
