The traces in the house were very old and covered with dust.

As early as fifty years ago, Senior Tom cleared out everything here.

Dumbledore had a complicated expression.

"I thought I knew all his secrets in the castle."

"It seems I was wrong."

He was very emotional about the past years, his eyes full of nostalgia, as if he saw a handsome young man sitting here, holding a book with an enthusiastic look across the long river of time.

"That's how Dumbledore is. He always thinks he should know everything." Snape sneered, "So, do you know where the Dark Lord is now?"

Dumbledore turned around and looked at Harry: "Do you have any ideas?"

"He's hiding from me." Harry shook his head. "A basilisk, such a big target, but I can't sense anything."

This is very abnormal.

Even though he didn't have the senses of a witcher, he still had the ability to speak Parseltongue. A snake was crawling inside the castle wall, and he never heard a word of Parseltongue.

Is this possible?

"Perhaps what happened last year has alerted him." Dumbledore said softly, "But a remnant soul can't do much."

"I'll have the house elves keep an eye on everything in the castle."

Harry hesitated. "Tell them to pay more attention to Ginny Weasley from Gryffindor, and Joseph Sheffield."

"Why them?" Dumbledore was a little surprised. "I remember Miss Weasley is only in the first year?"

"They were both the same. They didn't attend the Halloween dinner or the Quidditch match, and they were always alone," Harry explained.

He heard Professor McGonagall questioning students who were not on the Quidditch pitch.

Ginny's answer was that she was not feeling well and stayed alone in the dormitory, and then went directly to the bathroom. No one could corroborate her.

Joseph Sheffield had similar reasons to Ginny, and no one noticed him either.

"I will." Dumbledore nodded solemnly.

They left the secret room.

Professor McGonagall, who had been standing guard at the bathroom door, cast a concerned look.

Dumbledore explained to her that Snape walked Harry to the door of the Gryffindor common room, watched him go in, and then turned and left.

Most of the little lions had gone back to their dormitories to rest, but Ron and Hermione were still doing their homework in front of the fireplace.

Wait until Harry comes over.

Hermione looked up and asked nervously, "Harry, is it resolved?"

"No." Harry shook his head. "He was very perceptive. Everything was transferred away."

Both of them looked gloomy.

"We know what the monster in the Chamber of Secrets is." Harry continued, "It's a basilisk. You can prepare some tools. I remember its weakness is the crowing of a rooster."

Ron's expression was a little distorted.

His Transfiguration skills are pretty good, but at best he can only transform into microscopic creatures, such as ladybugs and sparrows. It is difficult for him to transform into a rooster.

Could it be that...

Want to keep a rooster in your dorm?

"Well, Harry, you have to help me." He sighed and muttered, "My Transfiguration skills are still a little bit off."

"Wait a minute, where's Neville?" Harry turned his head and looked around. He saw the person he was looking for on the other side of the table and waved at him. "Neville, please come over here."

Neville came over with the parchment in his arms, his face a little red: "Harry, you have to wait, I haven't finished looking at the homework yet."

"It's not about homework." Harry shook his head.

Neville breathed a sigh of relief.

"I wanted to ask about the Deathday party that day," Harry continued, "I just wanted to ask if you encountered anything strange."

Neville's face changed, the redness faded and turned pale, it was obviously not a very pleasant memory.

"When did you and Ginny go there?" Harry asked. "Be specific."

Neville frowned, trying to recall, and stammered, "We agreed to meet in the lounge at seven, but she was late, about ten minutes."

"Then we went to the Deathday party together, and nothing strange happened on the way."

"But the Deathday party was terrible."

"They are all ghosts, and a group of headless knights have also arrived."

"There was nothing for us to eat. The food was all rotten and smelled terrible. We all felt very uncomfortable. Ginny made the excuse that she was not feeling well and left first."

"You stayed an hour longer than Ginny?" Harry said with a hint of sarcasm. "Who dares to say that you don't have the courage? If it were me, I would probably leave with Ginny."

Neville's face turned red again and he shook his head violently, "Not that long. I only stayed for about twenty minutes longer, just as the band finished their fourth song."

"When I came back, the corridor was very quiet, and I couldn't hear the noise from the auditorium, which I used to hear from the grand staircase."

"Then, I saw Mrs. Norris."

Hermione noticed something and looked at Harry in surprise.

Ron muttered, "Twenty minutes is a lot. When I think of the rotten food, I don't think I can stay for even a minute."

"Neville, are you looking at your spells homework?" Hermione suddenly asked.

Neville nodded and sighed, "The Expansion Charm is difficult. I tried several times, but every time it was the same as Seamus's."

"Me too!" Ron found his confidant, "How can someone be able to perform smoothly just after learning it?"

They both looked at Harry and Hermione resentfully.

It's them, the culprits!

They were forced to write a seven-inch-long paper with no fewer than five hundred valid words.

"You have Charms class on Tuesday afternoon, why don't you work harder?" Hermione waved her hand.

Ron held his homework and huddled together with Neville, struggling in pain.

Hermione tugged at Harry's sleeve and led him to the other side of the fireplace. She lowered her voice and stared at Ron's back carefully: "Are you doubting Ginny?"

"See?" Harry nodded.

"Only Ron, that idiot, can't see that." Hermione frowned, "But why is it Ginny? She's only in the first year."

Harry also lowered his voice: "Don't forget, Mr. Weasley and Malfoy had a fight during the summer vacation. Maybe it was at that time that Malfoy did something."

"Ginny wasn't there both times."

"She left the Deathday party twenty minutes before Neville, but she returned to the Great Hall only about ten minutes before Neville."

Hermione opened her mouth with a complicated expression: "You remember all this?"

"Voldemort's residual soul is also very powerful." Harry lowered his head and looked at his hands. "I will find a chance to try her."

Hermione nodded, "I'll keep an eye on her for you, too."

Harry was about to speak.

She continued to speak, blocking Harry's mouth: "I know, I will be very careful. After all, I am a witch. What if Ginny is possessed by... a mysterious person? There will always be something strange."

"By the way, should we tell Ron about this?"

Harry was silent for a while, looking at Ron who was discussing with Neville with great interest, and then at Percy who was sitting at the door of the lounge, reading a book meticulously: "If there is anything, tell Percy later."

Ron was still young, only a year older than Ginny.

the next day.

The little wizards could not escape the fate of having to go to school on Monday.

They walked out of the common room and were surprised to find that the decoration of Hogwarts had changed drastically overnight.

There are two huge rooster statues at the door of each college lounge.

There are also some inexplicably noisy roosters in the portraits in the corridor.

Even the armor in the corridor turned into metal roosters.
