Hermione, let's start the revolution at Hogwarts

But they searched the castle and found no trace of Blake.

"Could it be from the Forbidden Forest?" Grindelwald said.

"Impossible, centaurs are actually very... you know, a little bit sensitive to territorial awareness, and there is also a fire dragon and various dark creatures living inside." The honest Hagrid quickly rejected the proposal.

"He has an accomplice, Rubeus, a powerful wizard."

So Grindelwald led Nietzsche to the edge of the Forbidden Forest.

Now, there were only two of them, and Nietzsche noticed that the professor twisted his body and made a crisp "click" sound.

"Nietzsche, how involved are you in this matter?" He suddenly stopped, leaning against a tree trunk and looking at the other person, "In other words, how much do you know about your 'invisible friend'?"

Now that the professor would ask this question, although it was a bit surprising, it was still within his expectation.

An invisible adult wizard followed a young wizard, and now that something like this happened, it's hard not to imagine that Granger was the one who helped Sirius Black.

"I don't even know what happened...Have you ever fought with her?" Nietzsche didn't take it seriously.

He was still thinking about Sirius and Granger's relationship.

Ah, no, it should be in the future of the parallel world, what is the relationship between Blake and Granger, so that after she comes to this world, she will choose to help.

Is this something she needs to make up for?

"She is very young, very talented, and has experienced hundreds of battles, but the strange thing is...she has never made a killing move." Grindelwald touched the short beard on his chin and recalled, "She also seemed to be trying to prevent Blake, but saved him in the end.”

She must know Sirius very well, but with her cautious look, she will always maintain the title of 'criminal' above his head.

If Granger really did it, she would definitely...

"She will come to me again." Nietzsche said with certainty.

He had what Granger needed.

That night, the search yielded no results. When Nietzsche returned to the auditorium, he found that all the hundreds of students had fallen asleep, four long tables had been moved to the base of the wall, and these 'worm chrysalis' were scattered on the ground.

Hermione was still asleep. When she saw him coming back, she just pointed at the sleeping bag at her feet, as if she had been waiting for him to come back.

"Sorry, I couldn't find Crookshanks..." Hermione yawned and whispered.

"It doesn't matter, it has a very sharp nose and will run away if it smells something wrong."

But Nietzsche was more suspicious that Crookshanks was staying with Granger.

He urged Hermione to get into her sleeping bag, while he leaned under the door of the Great Hall to stand guard.

Until midnight, Nietzsche, who was dozing off, noticed someone pushing him. His legs had begun to stiffen from bending his knees for a long time. He wiped the saliva from the corner of his mouth, leaned his back against the door, and straightened up with the strength of his waist.

"Nothing unusual was found, sir..." He said drowsily, as if talking in his sleep.

But the only response to Nietzsche was the sound of snoring one after another.

His palms were tickled by thorns a few more times. He opened his eyes and found that Crookshanks had crawled in through some hole. It was wet and covered with dust. It seemed to have squeezed in through the gap in the window. .

Aha, someone is looking for me.

As soon as Nietzsche got up to go out, he heard Hermione calling him.

"Nietzsche...where are you going...to?"

But the next second, he felt relieved, because Hermione was just talking in her sleep. She turned over and muttered: "You haven't finished your class today...no...don't run, hehe. ..”

If Nietzsche had to retake his studies for some reason in the future, he would never take Professor Hermione Granger's class until his death.

There was no one in the hall anymore. The professors were probably still having a meeting in the principal's office, discussing how to prevent the Ministry of Magic from letting dementors enter the school. Crookshanks leisurely walked in front and led the way.

What's even more amazing is that although the road led by Crookshanks went round and round, they were not discovered by the patrolling Armor and Mrs. Norris at all.

Many times, it just happens.

He followed his cat all the way to the eighth floor and stopped in front of one of the tapestries with a picture of "Troll Beating Barnabas"... Crookshanks just squatted here, seemingly admiring it. This piece of art.

"What kind of mechanism is this?" Nietzsche asked it.

"Meow."

"Okay, if it is, you shout 'meow~', if not, you shout 'meow!'"

"Meow~~"

"You dragged out the sound for an extra second." Nietzsche didn't understand what he meant.

They say pets follow their owners. He is so smart, but why can’t his cat understand human speech?

Crookshanks stuck out his tongue, licked his lips, and made a series of disgusted grunts. He didn't understand either. They said Nietzsche was a genius, so why couldn't he understand what he said?

"What it means is that this place is more than just some kind of mechanism." Granger walked out of the shadows, "This is the first time I saw someone talking to a cat."

She shook her head repeatedly, as if she was hesitant to speak.

After walking back and forth in front of the tapestry three times, Nietzsche saw her closing her eyes and thinking for a while. A door immediately appeared on the wall...an iron door that looked very much like the Trial Hall of the Ministry of Magic. gate.

She crossed her arms, turned her head, and looked at Nietzsche, who was a little dull.

"Aren't you afraid that I will kill you?" she threatened, "There are no other professors here."

"I am so scared, but I am more afraid that Hermione will have a bad character like you, Hermione Granger~" Nietzsche rolled his eyes, turned the handle above, and pushed the door open.

It was very dark inside, and it looked no different from a dungeon.

In the corner where the candle could not reach, a man with sunken eyes and chapped lips was tied there with chains and shackles. He was pale, as if any small movement would cost him his life.

"I thought he would be stronger." Nietzsche complained.

How did he get out?

And no one would have thought that Sirius Black, who was wanted by the magic world, was imprisoned inside Hogwarts.

Volume 1: Chapter 171 Dogs and Mice

I will take a day off tomorrow. Come on WBG. I don't ask for the championship, I just want to have fun. If I win, it will be even better.

-----

"Where is this?"

"Room of Requirement, you don't even know this place... That's right, you're only in the third year."

Nietzsche got the new secret room inside Hogwarts again - just walk back and forth three times in front of the tapestry of "Troll Beating Foolish Barnabas" on the eighth floor, and the room you need in your mind will appear. This is so convenient.

As a communication tool, Crookshanks returned to Nietzsche's arms after completing his task.

And the dizzy Black looked at the two people chatting leisurely and didn't recover.

Where is he?

"If it weren't for you, I would have caught him." Sirius Black shook his head, there was no trace of spirit in his gray eyes, and there was no regret on his face. He just hoped that the two people in front of him would listen to him.

Granger stepped forward and slapped him, so clean and neat that Nietzsche didn't react.

But this slap made Black calm down a little, at least it made him pay attention to his situation.

"I understand that you want to hand me over to the Dementors first, and I completely accept it, but just let me catch one person..."

"Why do you think we will let you take Harry Potter away?" Nietzsche frowned, turned his head and said impatiently to Granger, "This matter can be dealt with directly by other professors."

When Black heard Harry, he raised his head, twisted his body vigorously, and sat up from the ground.

"No! I won't hurt him." He roared excitedly, "I want to find him... that rat! I saw him in the newspaper, please, just let me kill him, I will do anything!"

His saliva splashed from his mouth, making Nietzsche take a few steps back.

But unfortunately, Black could not see any fear, worry, or other emotions on Nietzsche's face. He was so hard-hearted to Black that he gave up some of his little thoughts:

Originally, he was going to make Nietzsche have some sympathy, at least to help him remove the chains tied to his body.

"Exchange." Granger sat aside, trembling and lifting her left sleeve to reveal the wound underneath.

That was probably the mark left by the professor, which looked like a burn. When she tore the cloth that was stuck to her skin, Nietzsche's heart trembled. It hurt just to look at it, but she just hummed a few times.

There was no obsidian fireproof potion now. In order to prevent the wound from being infected, Nietzsche used a freezing spell to put the wound on Granger's left arm in a 'frozen state'.

"Thank you..." Granger said softly, "In short, whether you hand it over to your own Dean Snape or Headmaster Dumbledore, you can save a lot of time."

"Great, making a deal with a Slytherin, this is the stupidest thing I have ever heard." Black said on the side.

But Granger was surprisingly calm today, and did not follow up with the other party's words to ridicule Nietzsche. If it were usual, she would definitely say: Yes, if there was a choice, I would not make a deal with the stupid Slytherin.

What made Nietzsche even more flattered was that Granger was actually helping him speak.

"Gryffindor, who only believes in friends, seems to have paid the price for his stupidity, right? In fact, after seeing so many dead people, I don't care what house the person who dies in the next second will be from..."

"What do you mean." Black growled like a dog.

But Nietzsche and Granger ignored him.

At present, Black's only attribute is "goods", and Granger's "thank you gift" to Nietzsche includes but is not limited to this "goods".

"Muffliato (close your ears and plug your ears)"

Then Sirius Black couldn't hear what the two were talking about. His ears were full of buzzing tinnitus. When he finally got used to this feeling, the other party had turned his back and couldn't even see the shape of his mouth.

"Let me be frank. Black in the parallel universe is innocent, but this is a parallel universe. I have no evidence to prove that Black in every timeline is innocent..."

This thank you gift is the right to choose.

It's like in a story, Nietzsche has the ability to rewrite the story and has a lot of initiative, unless he hands it over to others, such as Dumbledore, Snape or Harry Potter.

Nietzsche can be in the initiative of a series of events surrounding Blake.

"What's the matter with the mouse?" he asked.

"Ron Weasley's rat Scabbers is actually an Animagus. He ran to a pet store to avoid the Death Eaters and was later bought by Percy, so Black was looking for him."

Things were a bit dramatic, because Nietzsche learned Black's purpose from Granger.

The other party kept shouting "He's in Hogwarts", but in fact he saw the photo of the Weasley family winning the gold Galleon Prize in the Daily Prophet and found the Animagus.

And that person was Peter Pettigrew.

"If Black had no evidence back then, how was he sentenced?" Nietzsche frowned. It seemed that the progress of the magic world in the law was more worrying than he thought.

"Accused, and when Black was found by the Auror, he was at the point where the street explosion occurred."

The number one suspect, plus the accusation, the crime was naturally determined.

But this was not difficult for Nietzsche. If he wanted to see whether Black was normal, he only needed one person-Gilderoy Lockhart.

Well, this guy is really annoying, but it must be said that he is very skilled in a series of memory spells and can easily do things that others can't do, and "extracting memory" is a piece of cake.

But what is more curious is that didn't Black have a truth serum back then?

"Due to your experience, I thought you were going to deal with it yourself or give it to Harry." Nietzsche said doubtfully.

In general, this matter is also half of Harry Potter's family affairs. After all, Black is still labeled as a "traitor". It was he who killed the Potters and blew up an entire Muggle street.

So it is understandable to let Harry Potter get involved.

"Because I believe in you, I believe you can do better, but like a loser like me, you are looking for ways to make up for your mistakes." Granger said, "You have the support of most of Hogwarts and the Muggle government behind you!"

Nietzsche carefully handed the time converter and the shrinking potion made in the potion class to her.

It turned out that he had so much hope in Granger's eyes. This exchange was nothing to him, because the knowledge and tips given to him by the other party were far more important than a Black.

"Seize the opportunity."

Granger patted his shoulder, then waved his hand and pulled Sirius Black in front of the two of them.

Since the Defense Against the Dark Arts professor knew of Granger's existence, Dumbledore would definitely know about it. Nietzsche had a very tight time. He had to figure out what kind of sword to make Sirius Black into to pierce the Ministry of Magic.

Corruption? Incompetence?

Of course, nowadays, only the wizards in Diagon Alley have contact with the outside world, so he has to work harder.

"You, tell me the whole story from Pettigrew blowing up the streets to being tried and imprisoned." Nietzsche said, holding his wand and sitting in front of him, "especially the people who accused you and the process of the Ministry of Magic's trial."

Sirius Black looked at him angrily and spat.

"Why should I tell you, this Slytherin bastard?"

"Because I can make truth serum." Nietzsche didn't care about his provocation at all and smiled gently, "The point is not whether you say it or not, but how I want you to say it. The one standing in front of you is the youngest potion master."

Hermione Granger, perhaps the youngest in history.

Crazy, Sirius Black swallowed his throat...Slytherin people are really crazy.
