Casto: They left Lockhart's office.

They tried to speed up their pace, and ran through the corridor despite themselves. When they reached the upper floor of Lockhart's office, Harry dragged them into an empty classroom and carefully closed the door.

Castor drew his wand and brightened the room.

"Do I say, should I tell them about the voice I heard?" Harry looked anxious.

"Don't say," Ron didn't hesitate, "it's not a good sign to hear voices that others can't hear, even in the wizarding world. ”

"If it were me, I wouldn't want to," Casto flicked his wand to let the shadows of the four sway against the wall, "and I'm not interested in helping with such unreasonable suspicion." ”

Hermione looked still brooding.

"I'll admit it's unreasonable," there was some hesitation in her tone, "but—"

"You believe me, don't you?" Harry stared at his three friends.

"Of course." There was no hesitation.

The expression on Harry's face relaxed.

Somewhere the bell rang.

"It's twelve," said Harry, "let's go to bed, but don't wait for Snape to come back to us and frame us." ”

.

For days on end, the students talked about the attack on Lady Loris, without talking about anything else.

Mainly, Filch's performance made everyone forget this incident for a moment. He often paced around the place where Lady Loris had been killed, as if thinking that the attackers would come back. He scrubbed the words on the wall over and over again, but in vain—the words still shimmered so brightly on the stone wall. When Filch is not patrolling the crime scene, he glares at two red eyes, stealthily hides in the hallway, and then suddenly pounces on the unsuspecting students, trying to find excuses to keep them confined, such as their "gasping too loudly" or "grinning faces".

He seemed to pay special attention to Harry and Casto, albeit with a fair amount of restraint.

Even the library was infected by the incident. The students' way of relaxing was to whisper about the strange events of the day, which affected Casto, who wanted to go to the secret room.

In one corner of the library, Castor, Ginny, and Ron sat Castor.

"It's a pity, I want to feed Lady Loris some dried fish." Casto withdrew his gaze from Ginny's paper and looked at his book.

"I've done this when I started school, and it looks pretty happy." Ginny's expression was a little sad, "Thank you, I'm done." ”

She rolled up her Potions homework and hurried away with her book in her hand.

Castor frowned and stared at the ancient scripts in the book.

There was the sound of smashing on a chair.

"Harry?" Casto glanced at him, "Did you meet Ginny?" ”

Harry blushed. He was held in Potions class, and Snape told him to stay and wipe the multichaete off the table. He bumped into Ginny head-on at the library door.

Ron looked up as well, having been agonizing with a ruler to measure his history of magic homework. Professor Binns asked the students to write a three-foot-long essay on the "Encyclopedia of Medieval European Wizards."

"Where's Hermione?" Harry asked hurriedly.

"Hermione?" Ron was furious all of a sudden, "She's gone to find the book!" Her homework has long been done! Also wrote a full four feet seven inches! And the words are written very small, very small! ”

"I'm eight inches short of that......." Ron was frustrated again, he measured his paper diagonally, "No, it's only seven inches short......"

"Actually, it's pretty quick to make up your mind to do it." Castor turned his quill and stared at the pages in distress, "You just need to turn the pages and quote more—you're just troublesome, just like me." ”

Ron sighed.

Harry sat down, grabbed Ron's tape measure, and spread out his homework.

He told his two friends that some of the students had just looked at him with a dodgy look.

"Because you have some chaete mucus on your clothes?" Ron quipped.

Harry's expression was grim, but he smiled.

"You're just noticing now?" Casto leaned back in his chair, "I think some people look at me with suspicion." ”

"Ignore them," Ron said immediately, "they're all goof-"

Hermione finally stepped out of the bookshelf. She looked very annoyed. Because she couldn't find the lore about the Chamber of Secrets, the only copies of Hogwarts, a school history were borrowed.

Of course, both Hermione and Casto had read the book and had some impressions. It doesn't write directly about the legend of the Chamber of Secrets, but it may find some signs that have been overlooked.

Harry and Ron looked at her with a feigned interest.

"So the next lesson is the history of magic," Hermione glared at them, "No." Don't go to Castor either. He has promised me. ”

The two pouted.

Castor ignored the resentful two.

The class bell rang, and they argued all the way to the history of magic class.

.

The history of magic is arguably the most boring course.

Casto sat next to Hermione, staring helplessly at the podium.

Professor Binns was so old and wrinkled that many said he didn't notice he was dead. When he was alive, he got up one day to go to class and accidentally left his body in an armchair in front of the fire in the faculty lounge. Since then, all his daily activities have remained the same, without the slightest change.

He opened his notes and read them in a dry, low, monotone voice. The class was almost groggy, even Hermione, who could tolerate the boring lectures, but focused more on the book than on the magical voice.

She flipped through her book, seemingly trying to find clues to the secret room.

Casto suddenly had a feeling that there were only two of them alive in the huge classroom.

As for why Castor is still awake -

He slept well in a single room at Hogwarts, so he had a lot of energy during the day. Even with the addition of a Fiona to the single room—he was used to it.

In addition, it may be because his body's magic resistance is full now, and he can hold this voice with a hypnotic effect.

Castor looked at Professor Binns again with interest.

He went to a ghostly death dinner on Halloween and was deeply aware of the ghost's helplessness. They are unable to touch physical objects, and even their senses are weakened to a certain extent. Barrow the Bloody tells him that Peeves, who is always troublemaker, is actually an elf, so he can throw things around - so many ghosts are very unfriendly to him and are actually jealous of him.

However, Professor Binns opened the notes.

Could it be that when he becomes a ghost, he can also bring his own notes?

Casto found it a little incredulous.

After all, ordinary ghosts only maintain their original appearance. Nick, who was almost headless, was wearing a ceremonial gown, the bloody man Barrow was stained with blood for some reason, and the fat monk was still dressed as a monk. But—

Notebooks are also part of Professor Binns?

Casto watched as he continued to flip through his notes.

Is...... Dedication!

Also, how did Professor Binns change his homework? There are obvious traces of correction on your homework?

Casto's eyes sparkled eagerly.

"What's wrong with you?" Hermione quietly pulled him and whispered, "You say, I'm asking Professor Binns about the Chamber of Secrets now—"

Castor came back to his senses.

"Of course, you already have an idea, don't you," Casto said expectantly, looking around the dead classroom, "the effect must be impressive." ”

Hermione poked him with her elbow in displeasure. But she raised her hand all at once.

Professor Binns was astonished.

"You're—"

"I'm Granger, Professor." Hermione said in a clear voice before Professor Binns mispronounced her name, "I wonder if you can tell us what's going on in the Chamber of Secrets." ”

Casto had already turned, holding his head on his hands, and looked at Harry and Ron in the back row with interest.

Harry's eyes were closed, his head was moving, and he looked like he was struggling half-asleep. He had a quill in his hand and looked like he wanted to take notes, but could only draw a few esoteric symbols. He looked up all at once, his eyes wide open.

Ron's face covered the unturned paper, lifeless, like a round stone on a piece of paper, and the stone was covered with red grass. He craned his neck suddenly, exposing his forehead, staring blankly in the direction the voice had come from.

Professor Binns blinked.

"My course is the history of magic," he said in a dry, breathless voice, "I study facts, Miss Granger, not myths and legends. ”

"I'm sorry, Professor. However, generally speaking, myths and legends also have a certain factual basis, and the scientific approach should be to find out the rational elements from them to find the objective existence of historical phenomena. Castor raised his hand.

"I'm Blake." Casto hastened to say.

Professor Binns looked at the two of them in amazement. He never seemed to have encountered such a situation, either alive or dead.

"There's some truth, you might say, the factual basis—" Professor Binns said slowly, "but what is 'scientific'—"

"Oh, when I didn't say it." Casto was a little helpless.

Professor Binns didn't seem to care. But what surprised and embarrassed him even more was that the whole class listened attentively to every word he spoke. He looked at them with dazed eyes, and saw every face turn to him.

"Oh, well, then," he said slowly, "let me think about it...... Secret Room ......"

Castor almost thought he couldn't remember. Because Professor Binns couldn't even remember Hermione's name, and she was still the top student in her class—

He slowly recounted the time when Slytherin and Gryffindor fell in love with each other.
