Severus, who left the common room, did not go straight back to the office, as a professor, there was a duty patrol every week, and today was Severus on duty.

Of course, it's not that you don't sleep all night, and under normal circumstances, students have a curfew at 9 p.m., and basically they can go to bed by 11 p.m.

In the middle of the night, there will be Filch and his cat patrolling, and if it's a special time, that's another story.

And the Hogwarts Castle of Nuoda is not a one-person patrol, usually there will be three people on duty at the same time, for example, today is Severus and Professor McGonagall on duty together, and a student will be arranged to be on duty together, usually the president of the student union, or the prefect of each house, etc., the staff on duty will have a fixed patrol area, such as Severus is responsible for the cellar to the third floor, and Professor McGonagall is responsible for the upper part of the third floor.

Severus planned to use the time to find the Headmaster's office in Slytherin, which was really too small.

And it's too private, anyone can come in, which doesn't help Severus do some other research, and the place is still small.

Although the chicken soup has been talked about in Slytherin today, none of this can change the fact that Slytherin really can't beat Gryffindor, especially if they can't use dark magic.

Slytherin itself has a smaller number of students, especially the upper grades, the sixth year is better, and the seventh year students may only be half the size of Gryffindor.

There were only ten seventh-graders this year, and six were lost, three of whom were incarcerated in Azkaban for various reasons, and the other three dropped out of school due to stress, compared to nineteen Gryffindors in the same period.

Coupled with the fact that the seventh year is already one of the strongest in combat, this means that Slytherin will definitely have the upper hand in the conflict with Gryffindor.

The gap in hard power is not something that can be bridged by a few words of blood, and these Slytherins may not be able to understand the meaning of Severus.

Therefore, it is inevitable to suffer losses in the early stage.

So the question is, as a dean, if you can't bring victory to Slytherin, what is the point of being the dean?

Besides, the Slytherin in the original book won the House Cup for seven consecutive years before Harry Potter entered the school, and if he didn't do well enough, wouldn't it mean that he was not as good as the original Severus?

This is an insult to Severus now.

So, if possible, Severus hopes to win all of the House Cups for the next nine academic years, all, not one!

Establishing the spirit of Slytherin, then, is a crucial step, and first of all, it is the duty of any Slytherin to lead Slytherin to victory over Gryffindor.

So the question arises, if there is no Severus to open a small stove, with the current Slytherin, why should they compete for the House Cup if they can't win!

Therefore, Severus urgently needed a larger environment as a practice ground for Slytherin, so that when the Slytherin students were full of bags, Severus, as the headmaster, could stand up with righteousness.

"That's it...... Tsk......"

At that time, you can laugh at them as much as you like, what "trolls", "snot", "head stuffed with scorpion"......

These words that Severus had prepared for a stomach come into use.

And it can also be a good reflection of Severus's "B grid", such a dedicated behavior, but in the end because you are too weak to succeed, I am really sad, teacher!

It's like marking your key points in advance and you didn't pass the exam, what's the matter? Shouldn't you be grateful that the teacher still sacrifices his spare time to give you private guidance?

As for the teacher's bad speech? Isn't this the depth of love and responsibility?

If you do this a few more times, the atmosphere of Slytherin should change significantly, plus this kind of guidance is easy to bring private goods, the upper grades may not have much impact, but the lower grades believe that day after day, they will soon break away from the hat of the dark wizard.

……

The Headmaster's Room of Slytherin is sure to have a suitable practice ground, as Salazar. Slytherin himself was fond of teaching dark arts to his students in private, which was one of the reasons why the founders parted ways.

And teaching the dark arts requires a space, although the common room in Slytherin is also large enough, but. It was clearly not a good place to practice magic, and it was not even private.

Maybe the other students and professors won't be able to get in, but what about Dumbledore? What about portraits?

Severus preliminarily judged that the Slytherin headmaster's room should also be underground, and it should not be far from the common room, and there might even be a secret passage to connect to the common room.

As a result, the cellar on the first floor has been the focus of Severus' searches.

However, considering that so many previous deans have not been found, it can be determined that the place is not only secret, but also the prohibition cannot be underestimated.

As a result, Severus adopted a simpler way of finding, using the Patronus Charm.

With Severus' current strength, he can already sense the simple emotions of the Patronus, so he can continue to release his Patronus everywhere, and then sense whether the Patronus has encountered the ban.

Although there are many prohibitions in Hogwarts Castle, most of them can be passed through by the Patronus, and only a few cannot, such as the Requirement Room, where the Patronus can only enter and exit.

After sweeping the entire cellar with a Patronus, as Severus had expected, he encountered two inaccessible restrictions, one of which was next to the Slytherin common room.

Continue straight from the Slytherin common room entrance, where there is a small utility room where one of the forbidden rooms is located.

If it's a purposeless search, there's almost nothing strange here, and the common probing magic can't detect anything, and there's no door that can be opened around, however, after finding the place, with Severus's strength, you can still find some clues.

Clean out the things in the utility room and get a feel for the forbidden position, which is not so much a utility room as the entrance hall, that is, the gate.

Covering an entire wall behind it, a delicate stone gate emerges that occupies an entire wall, larger and more beautiful than the Room of Requirement on the eighth floor.

Obviously, this is the Slytherin Headmaster's Office.

As for how to get in, don't expect Severus to know this, the way the various entrances to Hogwarts are entered is only notoriously weird, and he doesn't want to waste his time on it.

It's better to be violent, I don't think it will destroy the office!
