Due to the "Public Trial of Peter Pettigrew," both the teachers and students in the school and the officials of the Ministry of Magic were quite familiar with this wizard hero who had finally been exonerated and restored to his reputation.

And it was no secret that Sirius Black had joined the Hogwarts faculty.

As early as the Hogwarts opening feast a few days ago, Professor Dumbledore introduced Professor Black to the whole school.

After that, in the Transfiguration classroom, Sirius Black also appeared with Professor McGonagall, acting as a teaching assistant to help everyone master those complex Transfiguration spells—even in some course content, Sirius Black stood directly on the platform and gave trial lectures on Transfiguration under Professor McGonagall's observation.

Frankly speaking, Minerva McGonagall was a little worried at first.

After all, since his school days, he had been a notorious problem student in the school. Compared with Sirius Black and James Potter, two once-in-a-century troublemakers, the Weasley twins were simply good kids.

However, after several trial lectures, Professor McGonagall's perception of Black quickly reversed.

Even with Professor McGonagall's critical eyes, she had to admit that this former problem student did have a very good talent for Transfiguration—the nearly ten years of imprisonment in Azkaban had smoothed out his arrogance. The stability and seriousness that Sirius Black now showed in the classroom fully qualified him to be a professor.

Therefore, when Hogwarts opened this round of job expansion, Sirius Black naturally transitioned directly to a full-time position.

But... Sirius Black, Hogwarts castle manager?

Hearing this, Minerva McGonagall, sitting in the faculty seat, was stunned, and the hands that were about to applaud stopped. She turned her head to look at Sirius, who was sitting on the other side of the table, with a strange, half-smiling expression.

If she remembered correctly, Sirius Black was still the record holder for the most disciplinary offenses at Hogwarts.

Compared to James Potter, who had calmed down slightly after falling in love, this member of the Black family had been the number one troublemaker that successive castle managers hated and had headaches over since he appeared in Hogwarts castle.

"Yes, I must emphasize that the disciplinary situation at Hogwarts has been quite serious in the past year."

Dumbledore cleared his throat, his eyes sternly sweeping over the students in the hall.

"Madam Pomfrey and Mr. Argus have complained to me more than once about this issue. I don't want to see anyone pointing their wands at their classmates in the coming year—therefore, based on the original castle manager, we have specially invited Professor Black to ensure that every corner of the school can be covered as much as possible."

The mixing of house students is not without its drawbacks. In the short term, this may even further stimulate conflicts.

However, from a long-term perspective, the original academy barriers of Hogwarts will gradually be broken. As the communication between students from the four houses becomes more frequent, in terms of the current number of wizard students, it is definitely more beneficial than harmful.

As for the disputes that may occur during the transition period, Dumbledore chose to accept Aileena's advice - let the dragon become the hero.

Gellert Grindelwald, Sirius Black, plus the white-haired dumpling hiding behind the scenes offering advice, if nothing unexpected happens, this year's Hogwarts may have the hope of becoming the school with the best school spirit and discipline in history.

Of course, at this moment, most students have not yet realized what this means.

At the Gryffindor table, the Weasley twins exchanged glances, revealing a mischievous smile without concealment.

"Hey, mate, did you hear that? Filch the Second is about to appear, our good days are over."

"Maybe, then we have to be especially careful recently, so as not to hand in a certain piece of parchment as a Transfiguration assignment... But if Professor Black gets lost in the castle, do you think we should give him directions?"

"That might be a little difficult, after all, it's been almost two years since I met Mr. Filch at night."

"Me too, every time it's just a passing by, it's such a pity..."

Fred whispered in unison with George, and they both chuckled silently.

As early as the beginning of last semester, the Weasley twins discovered a special little secret.

In the beginning, Professor Otto Apocalypticus often wandered around the castle, just like the most dedicated castle manager, carefully wandering back and forth in a certain area, especially the area from the Headmaster's office to the corridor outside the Gryffindor common room, which has become the most terrible disaster area.

As a result, for a long time, the Weasley twins were nervous, and once thought that this newly appointed "part-time disciplinary committee member" was going to take Gryffindor as a sacrifice flag - which is not a strange thing, almost every castle administrator likes to take Gryffindor as a sacrifice first, which has almost become a tradition of Hogwarts.

However, as time went by, George Weasley and Fred Weasley took the initiative to contact each other, and also combined some descriptions of the students who met the professor in the corridor. They quickly judged from Professor Otto Apocalypticus' confident words and contradictory actions...

This old wizard from a foreign country seems, maybe, most likely is a walking GPS failure?

"Fred, George, restrain yourselves a little bit recently..."

At this moment, Bill Weasley frowned slightly, thoughtfully looked at Professor Black, who looked a little haggard at the end of the faculty table, and reminded him worriedly.

"That Professor Black may not be as simple as you think, he is different from Mr. Filch."

"Don't worry, Bill - we have secret weapons!"

Fred Weasley winked and said mysteriously.

Seeing that Bill seemed to want to continue to give some instructions, George Weasley patted him on the shoulder carelessly.

"We can't be caught! In this castle today, maybe we are not as powerful as Miss Kaslana in terms of destructive power, but in terms of skipping classes and night tours alone, you can't find anyone more powerful than us!"

"Hopefully..."

Bill Weasley shrugged his shoulders indifferently.

Although he didn't know where Fred and George's confidence came from, but based on his understanding of his younger brothers, they probably had some strange reliance - there are many problem students in Hogwarts, but over the years, people like George and Fred who are naughty on the one hand and have never made a mistake on the other hand are really too rare.

Unfortunately...

Compared to his younger brothers' cleverness and luck, Bill believed in the Fairy Queen's vision more.

As a B-level member of the SCP Foundation, he has seen too many incredible things during this period of time.

Most importantly, Bill Weasley knew very well what a desirable place Hogwarts would become next, and the pressures that those qualified to take on the duties of castle manager might face during this special period.

Thinking of this, Bill glanced at his two younger brothers meaningfully.

Since he and Charlie graduated, Fred and George have indeed become a bit lawless in recent years.

Disregarding authority does not mean that you don't have to abide by the rules. If you can take this opportunity to let Fred and George experience some setbacks in school, it may not be a bad thing, at least you can avoid them paying a heavier price later.

……

Along with Dumbledore's introduction, a few cold, sparse applause rang out in the hall.

As a young professor, Sirius Black received even less applause than Umbridge.

Apart from Harry Potter and Draco Malfoy, two young wizards who had a good relationship with Sirius, most students clapped politely, or simply sat in their seats without moving.

Of course, part of the reason for this may also come from the "disciplinary committee member"'s deduction of points.

Just like the Weasley twins, many young wizards suddenly lost a lot of enthusiasm when they heard that Sirius Black would also serve as the castle manager and patrol the castle with Argus Filch to investigate disciplinary violations.

"Hey, Harry, don't clap stupidly."

Hermione, who had returned to the Gryffindor table, gently poked the boy next to her and said softly.

"Look at Professor Snape, I guess you're in trouble later, you better consider who to help in case the two of them fight."

Snape is the Head of Slytherin House, and everyone knows that he doesn't like Gryffindor, but Harry Potter is an exception - perhaps because of Harry's seriousness and talent in Potions class, or for other reasons, in short, even Snape, who always hates Gryffindor, sometimes shows favoritism when facing Harry.

Hermione would swear on her wand that she had seen Snape secretly hint at Harry more than once when he was patrolling the classroom.

Undoubtedly, just like Aileena in Professor Apocalypticus' classroom, Harry Potter is definitely the student most valued by Severus Snape in the Potions classroom - even though Harry is also the one who is scolded the most.

"Hmm? What's wrong with Professor Snape?"

Harry said confusedly, and looked over following Hermione's prompt blankly.

At this moment, Snape was staring intently at the faculty table, his sallow, thin face almost twisted and twitching, and in the place where the wizard's gaze fell, Sirius was talking and laughing softly with Professor Lupin of Defense Against the Dark Arts.

In Hogwarts, Snape is probably the formal professor that Harry knows best.

Although at times, Professor Snape would be furious because of his some stupid questions, or some potentially dangerous operational errors, he had never seen such a terrible expression on Snape's face.

The expression was more hatred than anger.

In Harry's memory, even after Christmas last semester, when he forgot the homework assigned by Professor Snape because he was busy participating in Quidditch training, and tried to argue but was rudely interrupted by Professor Snape, it was not as good as one-tenth of the emotion written on the Potions professor's face now.

"As for our third and fourth professors..."

Dumbledore waited for the sparse applause welcoming Sirius Black to calm down, and continued.

"I am very pleased to announce to you that Hogwarts has welcomed two very experienced professors with profound attainments in their respective fields. Professor Horace Slughorn, who has served at Hogwarts for many years and has rich experience, and Professor Damocles Belby, who invented the Wolfsbane Potion and contributed it selflessly - in the coming year, they will serve as Potions professors together with Professor Snape."

Along with Dumbledore's introduction, Slughorn quickly stood up and waved gently to the students.

Slughorn's bald head shone brightly in the candlelight, and his big belly in a vest cast a large shadow on the table. Next to him was Damocles Belby, who looked a bit gloomy and had an aquiline nose.

Slughorn? Belby?

In the main guest seats of the hall, officials from the Ministry of Magic exchanged surprised glances.

This was not on the list they knew before. They originally thought that these two old gentlemen were also guests today.

Perhaps the students in the castle are a little unfamiliar with these two names, but as students who graduated from Hogwarts in the recent decades - whether it is Slughorn, the former Head of Slytherin and Potions professor, or Belby, who greatly alleviated the werewolf problem, they are too familiar with them.

Different from the few cold moments before, enthusiastic applause first sounded from the faculty seats.

Then, Slytherin House also quickly burst into warm applause.

If you add Professor Umbridge from the Ministry of Magic, so far, a total of three new professors who have appeared at Hogwarts have graduated from Slytherin, not to mention that one of them is their old Head of House.

With such an overwhelming advantage, Slytherin's success rate in winning the House Cup this year has at least doubled.

Among them, the happiest is undoubtedly the Slytherin seventh-year student who was just appointed as the President of the Hogwarts Boys' Student Union - with the help of the professors, Hufflepuff doesn't seem so invincible anymore.
