Professor Dumbledore asked all the students of the Gryffindor College to return to the auditorium, and asked Hufflepuff, Ravenclaw, and the heads of Slytherin College to bring the students of their respective colleges to the auditorium.

In everyone's eyes, Black really came, Hermione pulled Harry and William tightly.

"William, Black has really come to Hogwarts, what should we do? Harry is in danger." Hermione said nervously.

"I think Harry is safe," William said. "The dangers of dementors are greater than those of Black."

Hermione, Harry and Ron all looked puzzled

"Blake appears in Hogwarts, and the dementors have more reason to enter Hogwarts. I don't think this creature is friendly." William turned to Harry

"Harry, have you contacted Professor Lupin?" William asked

"Professor Lupin is really in poor health. He will guide me after his physical condition improves. I also saw Snape get medicine for Lupin." Harry said

"Snape? Will he be so kind?" Hermione said

"No, Snape must hate the professor in the Dark Magic Defense class," said Ron.

"William, you're not helping Snape lately," Hermione said, "Did you say?"

"Harry, what color is that potion and what does it smell?"

Harry was confused by Hermione's sudden question

"Harry!" Hermione looked at Harry and raised her voice

"Uh, it's green, it smells bad," Harry said hurriedly

Hermione turned to look at William

"William, I'm sure Professor Lupin is." Hermione didn't finish her words, and William interrupted her. William understood that Hermione wanted to say that Lupin was a werewolf and that it was very likely to help Sirius enter the castle

"Hermione, when Black came, Harry was with Lupin. Now Harry is standing here." William means that if Lupin was Black's accomplice, Harry would not be as safe as he is now.

"And, I think Dumbledore knows what you said, otherwise how could Professor Snape provide the potion for Professor Lupin?" William continued

Harry and Ron next to them didn't know what was going on

"What are you talking about?" Ron asked, Harry's face full of questions.

"Oh, I must be too sensitive" Hermione waved her hand and said to Ron and Harry.

"Let's go for dinner," William said to the three of them.

The atmosphere of supper was very depressing. Malfoy was obviously very proud of Harry's danger, while Gole and Crabb were a little nervous. Everyone was talking about what happened today, and the joy of Hogsmeade on the weekend disappeared without a trace. William regretted pretending to be Sirius now, after all, today's panic was caused by him. After dinner, Dumbledore stood up and

"The faculty and I will conduct a thorough search of the castle," Professor Dumbledore told the students, at which time Professor McGonagall and Frieve closed all the doors of the auditorium. "For your own safety, I think you may have to stay here overnight. I ask the chiefs to stand guard at the entrance of the auditorium, and the boys and girls student union presidents stay in the auditorium to manage it. Report anything to me immediately."

Professor Dumbledore paused for a moment and was about to leave the auditorium, and said, "Oh, by the way, you will need it..." He waved his wand casually, and the long table flew to the edge of the auditorium and stood against the wall; and waved it again, and the ground was covered with hundreds of purple sleeping bags. "Sleep well." Professor Dumbledore said, and he closed the door casually when he went out. The auditorium immediately heard an excited buzzing voice.

"Everyone is in the sleeping bag!" Percy shouted, "Come on, no one can talk! Turn off the lights in ten minutes!"

William and Hermione walked into the corner with their sleeping bags.

"Do you say Black is still in the castle?" Ron whispered anxiously.

"Dumbledore obviously thought so," said Hermione. "It's our luck to pick him tonight, do you know?"

William had already gotten into his sleeping bag. He was already very tired and needed rest. He fell asleep soon.

"William? William?" Hermione saw that Hermione had fallen asleep.

"William is asleep" Hermione turned to Harry and Ron and said

Everyone around them was asking the same question to each other: “How did he come in?”

"Maybe he knows how to hide," said a student from Ravenclaw's school a few feet away, "it's just that it appears from the thin air. You know."

"It's probably because it was disguised," said a fifth-grade student at Hufflepuff Academy.

"Or it would have been flying in," said Dean Thomas.

"To be honest, am I the only one who is not afraid of trouble reading?" Hermione said unhappy to Harry and Ron.

"It's very likely." Ron said, "Why?"

"Because this castle is not only protected by walls, you know," said Hermione. "The castle is also made of magic to prevent outsiders from coming in secret. It is impossible to enter in a submerged form. And I want to see what kind of costumes can deceive the dementors. These guys guard every entrance. If he flies in, they will see it. And Felch knows all the secret passages, they will seal them up."
