Hermione, let's start the revolution at Hogwarts

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

"Could it have come from the Forbidden Forest?" said Grindelwald.

"Impossible. Centaurs are actually very... you know, a little bit sensitive about their territory. Besides, there's a fire dragon and various dark creatures living there." The honest Hagrid quickly rejected this suggestion.

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

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

Now, they were alone, and Nietzsche noticed that the professor twisted his body and made a crisp "click" sound.

"Nietzsche, how much are you involved in this?" He suddenly stopped and leaned against a tree trunk to look at the other person, "Or, how much do you know about your 'invisible friend'?"

Although it was a bit unexpected that the professor would ask this question, it was still within his expectations.

An invisible adult wizard following a little wizard, and now something like this has happened, it is hard not to imagine whether Granger is the one who helped Sirius Black.

"I don't know what happened...Have you fought with her?" Nietzsche didn't take it to heart.

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

Ah, no, it should be about what the relationship between Black and Granger was like in the future of the parallel world, so that after she came to this world, she would choose to help.

Is this something she needs to make up for?

"She was very young, very talented, and experienced in many battles, but the strange thing is...she never killed anyone." Grindelwald stroked his short beard and recalled, "She seemed to be trying to stop Black, but she saved him in the end."

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

If it was really Granger who 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 hundreds of students had all fallen asleep. The four long tables had been moved to the wall, and these "insect pupae" were lying on the ground in a mess.

Hermione hadn't slept yet, and when she saw him come back, she just pointed to the sleeping bag at her feet, as if she had been waiting for him to come back.

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

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

But Nietzsche was more suspicious that Crookshanks was with Granger.

He urged Hermione into her sleeping bag while he leaned against the door of the Great Hall to take over the guard duty.

It was not until midnight that the sleepy Nietzsche realized someone was pushing him. His legs had begun to stiffen from being bent at the knees for so long. He wiped the saliva from the corners of his mouth, leaned his back against the door, and straightened up with the strength of his waist.

"Nothing unusual was found, sir..." He spoke in a daze, as if talking in his sleep.

But the only response to Nietzsche was the sound of snoring.

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

Ahaha, someone is coming to see me.

Nietzsche just stood up and prepared to go out when he heard Hermione calling him.

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

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 in the future due to some circumstances, he would never take Professor Hermione Granger's class.

There was no one in the hall anymore. The professors were probably still meeting in the principal's office, discussing how to stop the Ministry of Magic from allowing Dementors to enter the school. Crookshanks walked leisurely in front, leading the way.

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

Many times, we just miss it.

He followed his cat all the way up to the eighth floor and stopped in front of a tapestry depicting "A Troll Beating Barnabas"... Crookshanks just squatted there, seemingly admiring this work of art.

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

"Meow."

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

"Meow~~"

"You dragged the sound for one second longer." Nietzsche didn't understand what he meant for a moment.

It is said that pets take after their owners. He is so smart, so why can’t his cat understand human language?

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

"It means that there's more to this than just some kind of mechanism." Granger stepped out from the shadows. "This is the first time I've seen someone talk to a cat."

She shook her head repeatedly, looking as if she wanted to say something but hesitated.

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

She crossed her arms, turned her head, and looked at the somewhat dazed Nietzsche for a few seconds.

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

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

It's very dark in here and looks no different from a dungeon.

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

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

How did this get out?

And no one could have imagined that Sirius Black, who was wanted by the wizarding world, was imprisoned in Hogwarts.

Volume 1: Chapter 171: The Dog and the Mouse

I'm going to take tomorrow off. Come on WBG. I don't ask for winning, just have fun. If we win, that would 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 grade."

Nietzsche discovered a new secret chamber inside Hogwarts - he only had to walk back and forth three times in front of the tapestry of "The Troll Beats Barnabas with a Stick" on the eighth floor, and the room he needed in his mind would appear. It was so convenient.

Crookshanks, who served as a means of communication, returned to Nietzsche's arms after completing his mission.

Blake was dazed and couldn't recover from the sight of the two people chatting leisurely.

Where is he?

"If it weren't for you, I would have caught him." Sirius Black shook his head, there was no light 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 cleanly and firmly that Nietzsche didn't even have time to react.

However, this slap calmed Blake down a little, at least it made him pay attention to his situation.

"I can understand if you hand me over to the Dementors first, and I fully 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, "Why not let other professors handle this matter directly?"

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

"No! I won't hurt him." He roared excitedly, "I'm looking for him... that rat! I saw him in the newspaper. Please, just let me kill him, I'll do anything!"

His saliva spurted out of his mouth, causing Nietzsche to take a few steps back.

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

I had originally intended to arouse some sympathy in Nietzsche, or at least help him remove the chains that were tied to his body.

"Exchange." Granger sat aside and tremblingly lifted up his left sleeve, revealing the wound underneath.

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

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

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

"Great, making a deal with a Slytherin, that's the stupidest thing I've ever heard of." Black said on the side.

But Granger was surprisingly calm today and did not follow up with the other party to mock Nietzsche. At other times, she would definitely say: That's right, if I had a choice, I would not make a deal with the stupid Slytherin.

What made Nietzsche even more flattered was that Granger was actually speaking for him.

"Gryffindor, who only believed 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 next second will be from..."

"What do you mean?" Blake 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"

Then Sirius Black could no longer hear what the two were talking about. His ears were filled with buzzing tinnitus. By the time he finally got used to the feeling, the other person had turned his back and he could not even see their mouth shapes.

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

The gift of gratitude is the right to choose.

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

Nietzsche was able to take the initiative in a series of events surrounding Blake.

"What's the matter with that rat?" he asked.

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

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

The other party kept shouting "He's at Hogwarts", but in fact he saw the photo of the Weasley family winning the gold Galleon prize in the Daily Prophet and discovered 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 legal progress of the wizarding world was more worrying than he had imagined.

"Allegations, and that Black was found by the Aurors right at the point where the street explosion occurred."

With the prime suspect and the accusation added, the guilt is naturally determined.

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

Well, this guy is indeed annoying, but it must be said that he is very proficient in a series of memory spells and can easily do things that others cannot do, and 'extracting memories' is a piece of cake.

But what is even more curious is, didn’t Blake have truth serum back then?

"Given your experience, I thought you were going to handle it yourself or give it to Harry." Nietzsche said doubtfully.

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

So it is understandable that Harry Potter was involved.

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

Nietzsche carefully handed her the time-turner and the shrinking potion he made in the potions class.

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

“Take advantage of the opportunity.”

Granger patted his shoulder, then waved her 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 very little time left. He had to figure out what kind of sword Sirius could be made into so that he could pierce the Ministry of Magic.

Corruption? Incompetence?

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

"You, tell me the whole story from the time Pettigrew blew up the street to the time he was tried and imprisoned." Nietzsche held his wand and sat in front of the other person and said, "Especially the people who accused you and the trial process of the Ministry of Magic."

Sirius Black gave him an angrily look and spat.

"Who am I to tell you that Slytherin jerk?"

"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 ever.

Madman, Sirius Black swallowed...Slytherin people are indeed all crazy.
