The auditorium is filled with a strong festive atmosphere, and in addition to the usual jack-o-lantern and bat decorations, there are also some local decorations, such as some ghost models. Specialty snacks such as sugar skulls, blood sandwiches and tombstone biscuits also appeared on the table.

"Isn't it Halloween tomorrow, why does it look like a holiday today?" Ryan asked, a little strangely. Several of the surrounding classmates also showed puzzled expressions.

Hermione next to her heard the question and replied, "It's different from our British habits, Halloween here in South America is from October 31 to November 2, a total of three days. ”

It seems that wizards in South America have long vacations like Muggles, but this is a good thing for Ryan, after all, everyone likes holidays. At least from a dietary point of view, the Festive Diet of Castro Bruzzo is much more abundant than the usual diet.

However, Ryan's good mood did not last long, and he received several letters early the next Halloween morning. There are Weasley twins, Percy's, and even letters from Colin and Ron, who don't usually have much contact, all of which tell Ryan that something terrible has happened at the school: Sirius Black has somehow broken into the school, and he even destroys the portrait of the fat lady Gryffindor with a knife.

When Ryan arrived in the common room with the letters, he found that most of the people were waiting here, each with a letter or two in their hands. It's just that the news from the others is not as true as the news that Ryan has gotten, such as a nearby Hufflepuff student who swears that Blake was forced to escape after breaking into the Gryffindor common room and fighting a bunch of students for hundreds of rounds.

While everyone was standing in the room restlessly exchanging the news they had received, Professor Sprout walked into the room and counted the number of people and said, "Okay, you're all here now, I have something to say." Many of you may have received letters from friends at school about what happened at Hogwarts last night, so to avoid rumours, I'm giving you the official notice now. ”

"One, Sirius Black did enter Hogwarts Castle last night and destroyed the portrait of the Fat Lady without being able to enter the Gryffindor common room. Second, there were no casualties in the process, and I hope you don't spread rumors. Finally, it's a pity that we didn't catch Sirius, so I hope you can also advise your friends to try to cooperate with the school at this time and not mess around. With that, Professor Sprout glanced at Ryan.

It seems that the Weasley twins are notorious in school, and Ryan can only smile back with an embarrassed but polite smile to indicate that he knows.

After Professor Sprout finished speaking, everyone disbanded, and on the way to class, Ryan had been wondering what the defense of Hogwarts Castle was? In his previous life, many of the fandom he had read said that the headmaster could monitor the movements of the entire school, of course, this was not difficult from a technical point of view, after all, Harry Potter's father could do this, and it was not difficult for Hogwarts to have the same monitoring system in Hogwarts school.

But if you can really do the kind of real-time monitoring that some fandoms say, why didn't Dumbledore just catch Blake?

Of course, Ryan doesn't agree with the Dumbledore conspiracy theories that many fandoms say, after all, as the leader of the White Wizard, Dumbledore shouldn't be able to indulge criminals. Of course, under this premise, Dumbledore couldn't do anything to know that his subordinates had been wronged, and he still had his subordinates squatting in Azkaban for more than ten years.

The most likely explanation is that Hogwarts' surveillance system can only show who is and where, but all this requires people to watch all the time, and there is no automatic alarm function. And how could Dumbledore, as a headmaster, stare at the monitor all day like a security guard.

That being the case, Ryan felt that he would have more certainty in Hogwarts Castle in the future, as long as he wasn't too lucky and avoided the portraits and ghosts.

Naturally, in this case, everyone can't help but discuss how Blake broke through the Dementors' blockade and infiltrated the school, but most people think that he should enter the school through some secret passages.

Because everyone is in Brazil now, Hogwarts is a little far away from them after all. So after discussing it for a long time, everyone left the matter behind. It's just that when everyone writes to their friends at Hogwarts that night, they can't help but have a few words of comfort.

However, the situation at Hogwarts was not denied by this incident, and just when everyone was about to forget about the previous incident, a new bad thing happened at Hogwarts.

It was the middle of November, and Ryan returned from dinner to find everyone in the common room discussing the upcoming house matches at Hogwarts. In particular, Ravenclaw students are very nervous about this year's competition, after all, because Zhang Qiu participated in this exchange activity, Ravenclaw can only find substitutes to play the game.

Although Ryan didn't have much of an interest in Quidditch, he joined the discussion for social purposes, occasionally saying a word or two to pretend that he wasn't a rookie.

While the discussion was in full swing, Hermione suddenly pushed the door open and walked into the common room, holding an open letter in her hand.

"Ryan, something happened at Hogwarts, the Dementors lost control and broke into the Quidditch pitch, and Harry fell straight from the sky. ”

As soon as Hermione's words fell, there was an explosion in the common room. Everyone started babbling to Hermione about what was going on. As Hermione read the letter, the details of what happened were slowly being constructed. To sum it up: the excitement and joy of everyone on the Quidditch pitch caused the hungry Dementors to get out of control, and Harry fell unconscious because he was too close to them, but Dumbledore intervened to chase away the Dementors and save Harry.

"I don't know why the Dementors were allowed to protect the school. ”

"This filth should have been eradicated long ago. ”

"What the hell is the Ministry thinking? What is the difference between Hogwarts and Azkaban? ”

While everyone in the common room was discussing the matter passionately, Ryan and Hermione returned to their carriages.

The letter was written by Ginny at Harry's bedside, and she said that Harry was in a bad state when he was taken to the hospital, his face was pale, and his whole body was shaking. So she wanted to ask Harry how to solve this problem now?" Hermione asked as she handed the letter to Ryan.

"As far as I know, there's only one solution that Harry has at his disposal right now. Ryan said.
