"What?"
Harry and Alvin were taken aback.
Harry was frightened by the name Sirius Black.
On the other hand, Alvin was outraged. He agreed with the other party not to act rashly, but he still forced his way into Hogwarts.
If it weren't for the inconvenience now, he would have liked to find Sirius directly and beat him up severely.
Soon, Professor McGonagall and several other Head of Houses came to the Great Hall.
"Quiet!"
Professor McGonagall stopped the commotion and maintained the order of the Great Hall.
Everyone was quiet when they saw Professor McGonagall speak, and Dumbledore suddenly appeared beside Professor McGonagall along with Fawkes.
Alvin's sharp eyes found that the professor seemed to be a bit dusty, obviously coming back from his other place.
Alvin had rarely seen Dumbledore at school this term, and the last time he met was when Dumbledore pleaded for Fudge.
Professor McGonagall whispered a few words in Dumbledore's ear, and Dumbledore frowned.
Then he looked at the students. "The professors and I will thoroughly search the castle."
At this time, Professor McGonagall and Flitwick had already waved their wands and closed the door of the Great Hall.
"I asked the prefects to stand guard at the entrance to the Great Hall, and the Head Boy and Head Girl were in charge."
Dumbledore continued to arrange matters for tonight. Percy looked proud when he heard it, as if he had been entrusted with a heavy responsibility.
Dumbledore waved the wand, summoned hundreds of purple sleeping bags, and left the Great Hall with a group of professors.
In an instant, the Great Hall was filled with the excited croaking of the little Gryffindor lions.
"It was Peeves who told us that the Fat Lady wouldn't open the door for Black, so he destroyed the Fat Lady's portrait."
Fred described the scene to Alvin and Harry.
"Did you say Black is still in the castle?"
Hermione said quietly, her tone a little anxious.
"I don't think no, no one is stupid enough to stay at a crime scene after committing a crime, especially when Dumbledore is here."
Cho didn't believe that Sirius would stay here and replied casually.
"You said how he came in quietly. There are so many dementors at the gate of the school."
A Ravenclaw girl also joined in. It had become a small tea party.
"It must be an Apparition!" Ron said firmly, but it was met with unanimous contempt from the others.
Harry pulled Ron and motioned him to stop saying anything, "You forget, Alvin said before that there is no way to Apparate at Hogwarts."
Ron blushed. He forgot about it.
Others were also talking. Some said he flew in, and some said he came in disguise.
The answers are also varied.
"Lights out now!"
Percy yelled, "I want everyone in your sleeping bag. Stop talking!"
"Look, the majesty of the male boss."
George said sarcastically, which drew a burst of a sneer.
Hermione and Cho looked at Alvin, who looked dazed, and called out to him.
"I'm fine. I thought Black wouldn't dare do anything tonight when Headmaster Dumbledore and the professors are around."
Alvin sent a message to Sirius, asking him to meet at the Shrieking Shack this weekend.
He'd have to figure out why Sirius came out like this.
After the lights went out, the topics of the students gradually shifted from Black to other places.
Many students are a little excited, and there are few opportunities for students from the four Houses to get together and chat in the evening.
Fred and George fully enlivened the atmosphere, telling everyone exciting stories about their night tour at Hogwarts.
Percy had come over several times but missed their presence, so he could only give a weak warning.
Alvin brought a few little witches to the corner of the Great Hall and cast a barrier to ensure that the outside voice would not disturb them.
Until late at night, most of the little wizards fell asleep.
And the professors would show up in the Great Hall every hour to see if everything was okay.
At three o'clock in the morning, all the professors gathered together to share the information they had obtained. They were standing not far from Harry.
"Have you found the portrait of the Fat Lady?"
"Hiding in the Map of Argyllshire on the second floor, she was so frightened that she was temporarily unable to do her job as a door guard."
Professor McGonagall said worriedly, obviously this time, Sirius brought great harm to the fat lady.
Dumbledore nodded, "Severus, do you have any clues over there?"
"No, I went to the tower on the west side and all the classrooms below the third floor and found no traces."
"As for the rest, you can ask Filch."
"Well, I guess Black's gone."
"How did he get in? Have you ever thought about it? With the defense of Hogwarts, if there are no outsiders..."
"Severus!" Dumbledore interrupted Snape, "I don't think anyone in this school would want to help him. You need to try to trust everyone."
Snape was a little unconvinced, "Yes, I used to believe in everyone, well, until you appointed Lupin."
Having said this, he took a deep breath, "You know, the relationship between Lupin and Black, don't you think it's a bit too coincidental? One person just escaped prison, and the other came to Hogwarts. The goal is Potter!"
"Okay, Severus, you know, Lupin is still resting in his office. There seems to be something wrong with your potion this time." Dumbledore reassured him, obviously wanting to end this time conversation."
"I need to go to the Dementors now. I'll let them know."
"Are they going to help too, sir?"
"Yes," Dumbledore's voice was a little cold, "but as long as I serve as the Headmaster, Dementors will never be allowed to enter this school. They have lost two members recently, and I need to have a good talk with them."
After speaking, Dumbledore just left, while Snape stood for a while with deep anger on his face and left.
What they didn't know was that, not far from them, Harry opened his eyes and listened to all their conversations.
