Outside the dormitory, you can see the students sloping away under Professor McGonagall's guidance, the fireplace is full of ashes from the over-burning of Floo powder, and Roger's newly changed clothes have just entered the lounge.

Caroline saw her brother coming downstairs and asked, "Our stove doesn't have that net, what should we do when it's our turn?"

"How's the Black house?" Harry just invited us. Hermione said that they were neighbors who had gotten together and would be able to get together when they got home.

"Young man, it's very kind~" Roger dragged Harry over: "Is your new house big enough, can it accommodate so many people?"

The little savior nodded: "If you live with me, it will be no problem for Hermione and Caroline to squeeze together..."

Roger glanced back at the old lady, and Caroline nodded her head to say no. Anyway, it's just a one-night stay, and it doesn't matter if you go home or go out the next day.

As for Neville and Ginny, they all have their own homes to go back to, and there is no need to follow them over and squeeze into Black's little house.

The students left quickly, and it wasn't long before it was Roger and their turn.

"7 Crescent Street, don't be mistaken. Harry asked, pulling out a pinch of shiny powder from a small bag in Professor McGonagall's hand with a frowning face, muttering, "I don't like this way of traveling at all..."

He stepped into the fireplace, threw the powder at his feet, and the green flame burst into flames.

"7 Crescent Street. Harry said loudly. As he spoke, the flames rose and engulfed his figure, and by the time the flames were extinguished, the little savior was gone.

Harry was followed by Hermione, who also legally concocted and disappeared into the flames, and then the Grangers. The Fireplace Trip Granger couple were also intrigued, but not as excited as Caroline, who had experienced it once before.

Caroline was eager to try it out, and although she had seen Roger use Floo Powder before (when she was in first grade to buy a new book), it was the first time that she had used it herself.

"Be sure to make the name of the place you go to, or the Floo Network will get confused and throw you out of the other fireplace. Seeing his sister eager to get into the furnace, Roger instructed.

Caroline gave her brother a reassuring look, and Floo Fan threw it away: "No. 7 Crescent Street!"

The flames burned louder than before, the green flames were about to reach Roger's eyebrows, and Caroline used a bit too much Floo powder.

Roger unconcernedly dusted off the ashes on his clothes, turned his head to Blake, who was talking to Dumbledore or something, and said, "Sirius, aren't you leaving?"

Blake waved his hand: "I still have some things to deal with, leave me alone." ”

The boy shrugged his shoulders and pinched a pinch of Floo powder to visit Blake's newly purchased property.

Roger's group dragged on to the end, firstly, because Harry and Hermione carried forward their style, and secondly, these little guys more or less did not want to leave this side, and after dealing with those scarecrows in the auditorium for so long, they felt that the strength of the adults was not much stronger, and they felt that they could also join the battle to help.

They are all good children with a sense of responsibility... Roger felt that his education should continue.

There were only four men left in the common room: Black, Bill, Professor McGonagall, and Dumbledore.

Mrs. Weasley led the child home, leaving Bill here to help, much to the twins' displeasure, but they couldn't get past his mother's big arm and were pulled back by the ear.

Mrs. Longbottom was too old, and was carried home by Neville first.

The four of them didn't stop long during the break, and walked briskly downstairs under the leadership of Dumbledore.

"Although the Headmaster has activated the defensive magic around the castle, I don't think it's likely to hold it for long, and we'll have to keep reinforcing it. "The outrageously powerful demon kings who also heard Roger say, Professor McGonagall said as she walked.

Blake and Bill were quite surprised: "How come? The castle of Hogwarts has been strengthened by the magic of successive headmasters, even if it can't be defended, there is no problem in holding on for a while..."

"No, if the situation that Roger said really happens, the castle's defenses will only last for a shorter period than you and I expected. There were no more students to comfort, Dumbledore said with a serious face.

Looking through Roger's memories, he knew how many things were in the mind of this strange student, and those memories were so large and incomprehensible that it would take many times as long for a wizard to roughly read them. Even so, he saw all kinds of monsters that were ridiculously strong from the many bizarre images in those memories.

But because those memories are too complicated, Lao Deng can't see what the monster that appeared in Hogwarts today is.

And... I'm really sorry, Roger played the Chinese version of Devil May Cry back then, and if Dumbledore didn't learn Chinese, even if he found this memory, it would be difficult to figure out what was written on the demon illustrated book in the game.

Professor McGonagall gave a general explanation to the two who didn't know the situation, and Blake's face suddenly turned cold: "If this really happens, we can't stop it at all," and then he glanced at Dumbledore, "But could this be Roger's bad bag coaxing us to play?"

Lao Deng shook his head calmly: "It shouldn't be, what Roger said is just a speculation, it may or may not happen, strengthening Hogwarts' defenses is not a bad thing." ”

"Could it be Voldemort's trick?" Blake said after a moment's silence, "You asked me to go to the forests of Albania to investigate during the summer vacation, and I couldn't accompany Harry to the Quidditch World Cup. ”

"It won't be his," Dumbledore denied, "I know him, and if this is really his handiwork, he won't be exposed in a place like Hampstead's nameless......"

But halfway through the words, Old Deng suddenly stopped facing the steps, and a lightning bolt seemed to pass through his mind, and suddenly connected the seemingly unrelated events that happened this year.

"Dense fog in the Hampstead district... Attract the elite of the Ministry of Magic... Midnight Raid... The Department of Mysteries was destroyed... Killing frenzy... Could it be that he has really returned?" Dumbledore's words were more like muttering to himself.

The three people next to him naturally heard these words clearly.
