I was expelled from Hogwarts?

Professor McGonagall was about to enter a room. After hearing the shout, he turned around and saw those familiar figures with a look of surprise.

Mr. Scamander... why are you here?

I came to the Department of Mysteries to apply for a piece of information about Azkaban. Rove walked towards Professor McGonagall, and he smiled: Professor, what are you doing here?

I... Professor McGonagall hesitated for a moment, glanced at Hermione out of the corner of his eye, and said softly, I'm here to do something for Professor Dumbledore.

Rove thought for a while, and suddenly realized that Professor McGonagall probably came to help Hermione apply for a time-turner.

Hogwarts students need to choose courses in the third year, and Hermione has chosen all the courses, there is a conflict in time...need to use the time converter.

Of course, not everyone can apply for the Time Turner. There must be a guarantee from the school to prove that the student has both good character and academic excellence, and the Ministry of Magic must approve it.

It is probably difficult for a student like Rove to succeed in the application. His study is indeed excellent, but his immediate family members are the key targets of stalking, and they belong to the type of students who fail the political examination.

At this moment, the circular wall of the hall suddenly rotated, making a loud rumbling noise, and the blue candles on the wall blurred into brilliant halos.

Soon, the rumbling died down and everything was quiet again.

Rove raised his head and looked at the whole room.

This is an ancient Greek amphitheater-style hall with walls and floors made of black marble.

Twelve black doors are evenly distributed on the wall, they are exactly the same, without any marks or handles.

As the wall rotated, the positions of the doors were all disrupted, and it was no longer clear which door was the original entrance.

Seeing several people looking at the room, Professor McGonagall explained:

There are twelve doors in the hall of the Department of Mysteries, one of which is the exit leading to the elevator.

The other eleven doors lead to ten special rooms, as well as an office.

Professor McGonagall, what's the matter with the rotation of the wall? Hermione asked curiously.

It's very similar to the stairs in Hogwarts. Professor McGonagall said:

Every time you enter a room and go back to the hall, the walls will rotate and randomly scramble the positions of these doors.

Then how do we find the room we want to go to? Shirley asked, Is it by luck?

Maybe... Hermione thought for a while, and said smartly: We can mark every door we enter, even if the walls are rotated and disrupted, we will know which rooms we have entered.

No. Tonks said suddenly, These doors are covered with magic, and the marks won't last long before they disappear.

That's right. Professor McGonagall explained patiently as if he was lecturing in a transformation class:

Actually, it doesn't have to be so complicated. You just need to choose the first door on the right every time you enter a room, don't go back, and don't bother with the other doors... Keep walking, and you can walk through every room without repeating.

Professor McGonagall pushed open a door casually, and she said softly, Come with me.

Everyone followed closely behind Professor McGonagall and entered a square room.

The room was almost empty, except for a huge glass water tank filled with dark green liquid in the center, and many milky white things were floating around in the liquid.

What is this? Shirley asked looking at the milky objects.

Rove watched them appear and disappear in the depths of the green liquid, gleaming eerily like slimy cauliflower.

He suppressed his nausea and said, Brains.

...

Why does the Ministry of Magic keep such a thing?

I heard Professor Dumbledore say... Professor McGonagall whispered:

The Department of Mysteries is studying how the brain produces thoughts, and they're also studying the differences between Muggle, Squib and wizard brains.

Anyway, these things are dangerous, they like to cling to people's heads, suck their minds out, and turn wizards into fools.

Hearing what Professor McGonagall said, everyone immediately moved away from the pool.

Professor McGonagall walked towards the first door on the right, she pushed the door and entered, looked at the boy again, and asked:

Rove, why are you back now?

Because of Peter, I have to come back, Professor.

Are you alone? Professor McGonagall asked with concern. Are Newt and Tina back?

No. Rove glanced at Professor McGonagall and said, But Professor Hicks came with me, she is at Hogwarts.

Oh, is Professor Hicks here too? Professor McGonagall said with a smile, I'll go back to school and see her.

Professor Hicks may not dare to see you for the time being. Rove carefully glanced at Professor McGonagall's face, and asked, You didn't go back to school yesterday?

No. Professor McGonagall asked strangely, What's wrong?

Professor Hicks' airship crushed the ceiling of the Gryffindor lounge, Rove whispered.

...

Professor McGonagall was still happy at first, but she suddenly stopped talking and looked a little autistic. Apparently, the boy brought her unhappy news.

They soon enter the third room, which is filled with fossils and specimens, which looks a lot like a mysterious circus.

On the shelves in the aisle, there are bottles and jars of different shapes and sizes used to preserve species, which contain specimens of various magical creatures.

Salamanders, stinging jellyfish, Mithra rats... There are many specimens that Rove can't recognize.

In addition to the specimens, there are all kinds of ancient fossils, those extinct magical creature fossils, which have been spliced ​​together to restore their appearance in life.

A group of people walked along the aisle and came to an old and dark wooden door. The door was full of cracks and looked ordinary.

This is the office of the Department of Mysteries. Professor McGonagall knocked on the door, then turned his head and said:

I'll go in first, it will be your turn in a while, do you know how to get out?

Go back the same way. Hermione thought for a while and said, Take the door on the left?

No. Mag shook his head and said: Come and go are the same, keep going through the door on the right, and finally return to the original hall, then go through the door on the right and leave.

The door creaked open, and a pale middle-aged man stepped out.

Professor McGonagall looked at the man and asked strangely: Where is Mr. Saul Crocker? He was responsible for reviewing my application before.

The middle-aged wizard said with a blank expression: Mr. Crocker is on sick leave. I will receive you, Professor McGonagall.

Professor McGonagall nodded, she walked into the office, leaving Rove and the others in the room.

At this moment, Xue Li suddenly pointed to the distance and said, Rove, look at that!

Rove looked in the direction of the ponytailed girl's finger and saw the skeleton of a fire dragon.

He widened his eyes, because the fossilized dragon bone was more than a hundred meters long.

Rove looked at Shirley and said in disbelief:

This is... the fossil lost in the Romanian Fire Dragon Reserve?

...
