After convincing Hermione, Ryan suggested going to the library to study together. But Hermione thinks that her eyes are red and swollen, and the image of crying just now is really not suitable for appearing in front of her classmates, and thinks that it is good to study in this empty classroom where no one is around.

Lane went upstairs to the dormitory to retrieve his school bag, and then returned to the empty classroom. Hermione had washed her face and cleaned up her two desks.

Hermione took out the notes that Ryan had copied from the lesson she had missed in the morning and began to make up for the lessons she hadn't taken that morning. While copying, he said to himself: "God, I can't believe I actually missed a lesson because of this matter, the levitation spell is a very important spell, and it will be taken at the end of the exam." ”

After finishing all the homework assigned for the day, Ryan looked up the window and saw that it was already getting dark.

"Well, I think it's time for dinner now, but today is the Halloween dinner, I heard that the Halloween banquet at Hogwarts will be very rich, and the decoration in the auditorium will be very beautiful, plus this is our first holiday banquet at Hogwarts, I think we can't miss it. Let's run faster, maybe we can make it to the banquet. ”

The two of them packed up their books and were about to push the door out, when they suddenly heard crackling footsteps from the other end of the hallway. Ryan seemed to have thought of something, grabbed Hermione, who was about to open the door and go out, and then opened a crack in the door to peek out.

Upon seeing Harry and Ron running over, Ryan pushed the door open and walked out.

......

After the morning lesson, Harry and Ron noticed that Hermione hadn't been there all afternoon, and Ryan had just gone upstairs to get a bag and then vanished.

When it was time for dinner, they went downstairs to the dining room to attend the Halloween party, and overheard Patil say to her friend Lavender that Hermione was doing her homework with Ryan in the empty classroom on the first floor, and although her eyes were still a little red and swollen, she was not hiding in the toilet and crying like she did at noon, and she was envious that Hermione could have such a friend.

Ron looked a little uncomfortable when he heard this. He told Harry, "Because Ryan is a bit of a nerd too, that's why he can be friends with Hermione." ”

Harry said, "I know it's a little uncomfortable for Ryan to ask you to apologize to Hermione at noon, but if he hadn't been in the common room to discuss homework, I probably wouldn't have been able to finish my homework lately, you know, Quidditch training takes up a lot of time." ”

Moments later, when they walked into the dining room and saw the colorful Halloween decorations, they immediately forgot about Hermione and them.

A thousand bats fluttered across the walls and ceiling, and a thousand more, like a low cloud, swirled above the table, causing the candle flames in the pumpkin's belly to flicker. The delicacies suddenly appeared on the golden plate, just like at the opening banquet.

Just as Harry was enjoying their meal, Professor Quirrell burst into the dining room, his large scarf slanted over his head and a look of horror on his face. Everyone stared at him, only to see him walk up to Professor Dumbledore's chair, lean back on the table, gasp and say, "The troll - in the underground classroom - thought you should know. ”

With that, he fell headlong to the floor and passed out.

There was chaos in the restaurant. Professor Dumbledore had to make a few screeching fireworks explosions on his wand's head before everyone fell silent.

"Prefect," he said in a deep voice, "lead the students of your academy to the dormitories at once. ”

Percy was naturally familiar with the idea of leading the students to the Gryffindor Tower.

On the way, they met some crowds of people hurrying in different directions, many of them with nervousness written on their faces, and even some timid girls sobbing quietly.

As they walked for a while, squeezing through a crowd of confused Hufflepuff House students, Harry seemed to think of something, grabbed Ron's arm and said, "I remember that Hermione and Ryan didn't know about the trolls yet, and I thought we were going to inform them." ”

Ron bit his lip.

"Oh, well," he said decisively, "but it's best not to let Percy see us. ”

They buried themselves in the Hufflepuff crowd and walked in the other direction. They walked through the empty side hallway, and as soon as they turned the corner, they heard hurried footsteps behind them.

"Percy!" Ron whispered, pulling Harry behind a large sphinx stone statue.

They looked behind the stone carving, only to see that it was not Percy, but Snape. He walked through the hallway and disappeared from their sight.

"What is he doing?" Harry asked in a low voice, "Why didn't he stay in the basement classroom below, with the other teachers?"

"How do I know!"

They followed Snape's footsteps as they faded away, creeping down another hallway, trying not to make a sound.

The rest of the way didn't come along, Harry and they had just turned a corner and came to the road in front of Ryan's self-study classroom. I saw Ryan come out of the back door of the classroom: "It's dinner time, what are you two doing here?"

Harry opened his mouth, just about to say something. Suddenly, the smell of smelly socks mixed with a public toilet that had never been cleaned came to their faces, and the four of them heard a low grunt and the sound of huge soles dragging on the ground.

Ryan's face changed dramatically, and he immediately beckoned Harry and Ron to hide in the classroom, after which they held their breath and hid in the shadows of the classroom.

Through the glass on the classroom door, they saw a behemoth walking through the outside of the classroom, taking advantage of the moonlight shining in through the hallway window. They found out it was a troll.

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.

Behind hermione she covered her mouth and let out a suppressed exclamation, and after listening to the troll's footsteps slowly walk away, the four of them came to the door and looked down the hallway.

They saw the troll stop at a door and peek inside. It wiggled its long ears, made a decision with its small head, and then lowered its head and slowly slipped into the room.

"The key is in the keyhole," Harry whispered, "we can lock it in so it doesn't hurt anyone." ”

"Good idea. Ron said nervously.

They turned sideways to the open door, their mouths feeling dry, hoping that the troll wouldn't come out of nowhere. Harry strode and grabbed the key in his hand, slamming the door and locking it securely.

"It's done!"
