After the dinner, all the students were kept in the auditorium.

Professor Dumbledore came to explain some things. "Prefects, guard the entrance to the auditorium. The presidents of the boy and girl student unions will cooperate with Professor Sprout to maintain order in the auditorium. If there is any news, send a ghost to report to me immediately."

After saying that, he waved his wand, and the long dining table flew to the side of the auditorium and automatically stood against the wall. With another wave, hundreds of soft sleeping bags appeared on the ground.

"You're going to need this..."

Professor Dumbledore said and left the hall.

But not everyone likes sleeping bags.

After obtaining Professor Sprout's consent, several senior students took out their wands and turned the sleeping bags into single beds of similar size, and the robes they took off were turned into thick wool blankets.

They had thought about this while they were having dinner just now. If they had to spend the night in the auditorium, they would definitely have to make themselves more comfortable.

Of course, it would be better if Professor Sprout would agree to make the bed bigger.

After that, more and more students began to try to deform their sleeping bags because they found it very interesting.

Professor Sprout not only did not object to this decision, but also stopped Percy who was about to step forward to stop it.

After all, there are enough seats in the auditorium, and making yourself more comfortable without disturbing others is the meaning of learning magic.

Besides, it was still early, and it would be better to find something for the students to do than to let them discuss Sirius Black.

Professor Sprout walked among the rows of sleeping bags...

"Nice Transfiguration, Miss Johnson," she said with a smile. "I bet this bed is very comfortable."

Gryffindor Chaser, Angelina Johnson, ruffled her hair proudly.

Unlike most hard beds, she also added a thick velvet mattress.

…

When Professor Dumbledore and Professor McGonagall walked into the hall again, they looked at the lively scene in front of them in surprise.

The auditorium had become a giant Transfiguration classroom, and everyone was taking the same class.

"Minerva, it seems that everyone is enjoying themselves." Dumbledore said with a smile: "I thought I was in the wrong place just now."

Professor McGonagall also smiled, "Yes, Albus, you are right."

This was the first time she relaxed since she learned of Black's presence in the castle.

"Then let's provide some help as well."

Dumbledore took out his wand and waved it gently. The hall seemed to have suddenly become much larger. The passage, which was originally a little crowded, was now spacious enough for two people to walk side by side.

This also means they can make their beds bigger.

Professor McGonagall was not idle either. She turned all the sleeping bags of the first and second year students into single beds like those in the dormitory.

As for students in third grade and above who have already learned secondary transformation... they are not within her scope of help.

Moreover, these sleeping bags were conjured up by Professor Dumbledore, and the magic power can be said to be quite stable, and they are almost indistinguishable from real sleeping bags.

So strictly speaking, this is not even a secondary transformation, it is simply a sleeping bag turning into a single bed.

Third grade...If you can't even do this, then you'd better just use a sleeping bag.

There are many such people, such as Harry and Ron from Gryffindor.

They struggled for a long time, but only made their sleeping bags look uglier. Finally, Hermione couldn't stand it anymore and helped them.

Next to them, Neville had already crawled into his sleeping bag without even thinking about doing anything extra.

Fred, George and Cho came over too.

"It feels so strange, as if we were living in the same dormitory..." Fred lay there, looking up at the enchanted ceiling.

Although it was cloudy outside, he was in a surprisingly good mood. "It's a pity that Cedric is not here..."

As a prefect, Cedric had to guard the entrance to the Great Hall and was not with them.

"Thanks to Blake..."

George turned his head and said, "Without him, we wouldn't have encountered such an interesting thing. To be honest, this is the first time I sleep in a bed that I made myself... Will it suddenly turn back into a sleeping bag in the middle of the night?"

"If you get an E (exceeds expectations) in Transfiguration, then not..." Kyle said.

"That's too bad..." Fred sighed, pretending to be embarrassed, "We got an O in Transfiguration, which obviously doesn't meet the requirements, right?"

"Maybe we can deliberately get a few wrong answers on the next test so we can get an E."

"Mom will definitely not be happy if she hears you say that."

After saying that, they both laughed at the same time.

Kyle ignored them.

However, when George mentioned Blake, they couldn't help but think of what had just happened.

"Tell me, how did Blake get into the castle?" Connor asked.

This is the question most people want to know.

Now Kyle could clearly hear several speculations being said around him.

"Apparition..."

"Flying in on a broomstick..."

"Turn yourself into a flowering bush..."

They said a lot, but basically none of it was reliable.

The castle was protected by special magic that prohibited Apparition, and it was obvious that the Dementors would not allow a man on a broomstick or a flowering bush to slip into the castle.

"Is it possible that he came in through a secret passage?" At this time, Qiu suddenly said, "Aren't there many secret passages leading to the outside of the castle?"

"Impossible, absolutely impossible." Fred said without hesitation.

George looked around and confirmed that Professor Sprout and Percy were on the other side, then he lowered his voice and said, "There are only two secret passages leading to the outside of the school.

"One of them is in the warehouse of Honeydukes, which Black obviously can't get into. Remember, he doesn't have a wand."

"The other one is in the Shrieking Shack. Although it's unguarded, the entrance is right under the Whomping Willow."

Fred continued, "If Blake dared to go out there, he would probably be crushed by the Whomping Willow as soon as he came out."

"We didn't hear anything wrong with the Whomping Willow tonight, did we?"

"Lights out now!" Percy shouted. "I demand that every one of you stop talking!"

All the candles went out immediately, leaving only a few silver ghosts emitting a little light, floating around and talking seriously with the prefects.
