Hermione, let's start a revolution from Hogwarts!

But Sherlock showed no sign of having done anything wrong.

Pshaw! You should know Nietzsche hasn't been back for two weeks straight!!

“Yes, yes, yes~ It’s hard to imagine that someone in the Holmes family would not want to die alone.” Sherlock said drunkenly, “I am your father, so I still have to remind you---be careful not to be kicked out by Mr. Granger.”

Nietzsche's face immediately turned red.

“I was taking care of her!” He threw the permission form that required a guardian’s signature at the other person’s face.

“Interesting. John said the same thing when Mary had a minor cold, and now they’re engaged… Let me see, aha, wizard’s summer camp.” Sherlock raised an eyebrow, speaking with unbridled gusto.

After Nietzsche wrote his fancy signature on the permission form, he continued to look at the third-year course schedule.

In addition to the required courses, the other six elective courses are: Magical Creatures Conservation, Ancient Runic Literature, Divination, Muggle Studies, Arithmetic Divination, and Alchemy.

Without a doubt, alchemy is a must, followed by Muggle studies.

The former was because of his job; the latter was because he wanted to know what a Muggle was like in the eyes of a wizard, and only by knowing where the wizard went wrong could he make the corresponding corrections.

As for divination...

“Who would choose this?” Nietzsche frowned, looking quite disgusted.

"Do wizards' divination predict the future?" Sherlock suddenly became interested.

"No, it's a 'prophecy,' not a 'prediction.'"

Sherlock immediately took a sip of his wine, grabbed an apple from the table, and started eating it. He instantly found the diviner utterly boring. He exchanged a glance with Nietzsche, and almost simultaneously voiced the reason for their disdain:

"A prophecy that makes expectations come true is self-fulfilling."

Robert Merton's Psychology.

Selective filtering can lead to expectations becoming self-fulfilling in another way, because people unconsciously shape their behavior to conform to the ideal expectations in their minds.

For example, in the same class, everyone saw the tall guy hitting the short guy. The others didn't think about why, but just because of this violence, they predicted in their hearts that "the tall guy is a bad guy", and thus ostracized and distrusted him.

Then, in the harsh environment, the tall man did indeed become a bad person, and people would say, 'See! We knew he was a bad guy all along.'

And so the prophecy came true.

“Then I’ll choose to study ancient Buddhism.” Ni circled the three elective courses in red ink and put the reply into the school’s owl mailbag.

He was wondering what Hermione would choose.

Maybe they'll end up like me?

But no matter what, I probably won't choose a divination class... right?

Nietzsche simply couldn't imagine Hermione, who maintained her rationality through restraint, spending all day clutching a crystal ball, acting like a gypsy, and tying a few cow bones to her curly hair—it was such a stark contrast.

But in reality, Hermione actually chose... to be precise, she chose everything, including Divination.

Nietzsche looked at the elective schedule filled with checkmarks and said incredulously, "How did you even think of including divination and magical creature conservation in your curriculum?"

“It’s me,” Grindelwald said from the side. “I think it’s very necessary to learn more about magical creatures. Many wizards will turn to the power of animals when their magic is not up to par.”

He really didn't want to think about what happened back then, because the more he thought about it, the angrier he became.

So all I could do was put on an air of 'being there'.

“Then divination?” Nietzsche looked at the girl and blinked. “I don’t think you’re the kind of person who would spend time covering yourself in incense and drinking tea while looking at a crystal ball.”

This only made Grindelwald more annoyed, and he angrily said, "Who told the prophecy to do that?!"

"The book 'Seeing the Future Through the Fog' mentions methods like tea divination and ox bone divination..."

As Nietzsche counted on his fingers, Hermione's eyelids twitched every time he mentioned a method that sounded far-fetched.

Grindelwald fared no better, as Hermione's eyes seemed to say, 'This is the prophecy you advocate?' Her face gradually darkened, and finally, she used the walnut wood in her hand to shut him up.

“I’m referring to real prophecy, not the kind of thing that Muggles can learn.” Grindelwald was very confident about this.

During his time at Granger's house, he read a lot of Muggle books.

Regarding his past prophecies, he finally understood how to operate them... but it was far too late for him, so late that he only grasped the workings of the 'prophecy' when he was almost dead.

Unfortunately, he failed to seize the opportunity presented by the Muggle World War II.

"The future that is truly predicted is the inevitable result of the combination of countless coincidences. A wise diviner should not just be an observer, but should take those coincidences into his own hands."

Hermione shrugged and reluctantly released the school's owl.

In any case, the school did not say that students could not select all the courses at once, or that they could not note on the course form that they could select a maximum of three or four courses. This means that the school allows students to complete all the courses.

As for the method, she believed the professors would always find a way.

A week before school started, the Grangers finally returned. However, when Mr. Granger, who was carrying all sorts of shopping bags, saw Nietzsche dozing off on the sofa, he felt a mix of emotions.

That feeling was a mixture of entanglement, reluctance, and hesitation; he almost started thinking about what to name his grandson.

But when Mrs. Granger entered the kitchen, she saw something else that surprised her—her daughter was setting up a cauldron on the stove to make potions, the cutting board was covered with chopped valerian roots and lavender, and there was a strange old man behind her.

After a brief explanation, they got to know the French guest.

"Good morning. If you don't mind, you can have some freshly grilled sausages." Grindelwald looked much more robust after tidying up and changing into the clothes he wore in Diagon Alley.

He was refined and courteous, a stark contrast to his previous impetuousness.

Hermione was initially worried that Professor Glendale might not be easy to get along with ordinary people, since most old wizards are quite rigid, but she breathed a sigh of relief after seeing the professor's attitude of taking a step back.

"It's...not bad..." Mrs. Granger used food to ease the awkwardness. "By the way, aren't you French? Why do you have a German accent and eat German food?"

The atmosphere turned hellish again.

“Because I hate Paris,” Grindelwald answered quickly, almost blurting it out.

He hates Paris, France, without exception.

Chapter 146 The Bustling Diagon Alley

A few days later, the Grangers got used to having a guest in their home, but it wasn't a bad thing, because the professor was very refined in his speech and manners, and could solve everything perfectly with magic.

Moreover, he could also take the place of both of them, leading Hermione and Nietzsche to Diagon Alley to buy new books.

However, when Hermione returned to the Leaky Cauldron, she found a familiar face there—Harry Potter. He yawned, lazily got out of bed like Nietzsche, and stretched in the sunlight by the door.

After Harry finished enjoying the free breakfast, he could go to the ice cream shop to do his homework under Florin Fosco's guidance, and in less than half an hour he would get a free box of ice cream.

Having just finished his essay on the history of magic, Harry saw Hermione and Nietzsche walking ahead of an old wizard.

"I'm here!" he greeted warmly.

Nietzsche rarely saw the kind of joy on Harry's face; his whole being exuded a longing for freedom, like a lion that had been untied from its ropes and run out of the circus.

As a friend, he was equally pleased... Taking control of oneself is something to celebrate.

"You're here to buy new books, right? Be careful of those monster books; I got bitten twice while I was packing my bag." Harry looked at Grindelwald curiously, then raised his hand to smooth his hair and cover the wound on his forehead.

However, Grindelwald had no interest in Harry Potter, even though he was called the 'savior'.

What he was more curious about was the other person's mindset—many people get lost in those empty titles, especially children like this, who are more likely to lose themselves.

However, it seems pretty good so far.

“Hmph, I don’t think her backpack can fit all those monster books.” Nietzsche glanced at the girl’s backpack and grinned mischievously. “This time she’s going to buy the entire Flourish and Blotts bookstore.”

“Oh! Right…” Harry seemed to have thought of something and pulled out “Thus Spoke Slytherin” from his backpack. “Right now, the best-selling novel in Diagon Alley, besides Lockhart’s flying cars, is yours.”

He didn't envy Nietzsche's fame, but rather his talent.

Just as Nietzsche and his two companions sat down, Florin, the shopkeeper, poked his head out from behind the curtain at the door. He glanced at 'Harry's friends' a few times, then withdrew, and when he came out again, he was carrying many boxes.

"It's free, absolutely no charge!" he laughed heartily. "That's great, two celebrities like my ice cream."

After he left, Nietzsche nudged Harry with his elbow and whispered, "It won't be long before there are three of us..."

"Eat your ice cream!" Hermione shoved a spoon into his mouth. "I don't want to be photographed as soon as I go out. That kind of treatment is better left to Harry Potter. He's used to it anyway."

Between her and Nietzsche was Grindelwald, whose bickering made him lose his appetite.

No sooner had he finished speaking than a 'click' sounded in the distance.

It was Colin, always on the front lines! He got a new camera and captured the intimate little gestures between Hermione and Nietzsche... In Colin's eyes, however, it was 'lovers' behavior'.

"Kreeve!" Hermione immediately lost her temper.

“It’s Harry! I don’t understand…did I do something wrong? I’m just getting used to a new tool.” Colin feigned ignorance. “My father was happy looking at those moving photos, so he got me a new camera.”

"This isn't outside. I can let you experience being petrified again!" Hermione said, trying her best to look fierce.

It might still be useful, since Colin Crevey is acting really sad.

"It's not good to joke about other people's painful experiences," he said, pouting.

"I..." Now it was Hermione's turn to feel embarrassed.

She suddenly realized the other person had a point, and just as she was about to apologize calmly, the other person ran away in a flash.

As he ran toward the main road, he shouted at another group of wizards whose backs were turned to the group, "Lavender! Parvati! Help! Granger is going to kill me! You're doing this on purpose! You owe me a chocolate frog!"

Hermione gritted her teeth, her suppressed anger and embarrassment finding nowhere to go, so she could only kick Nietzsche under the table.

Later, they encountered the Weasleys again. The three brothers led their sister out of the bookstore. Ginny was more lively than before and was no longer the listless girl she was in first grade.

"Look at this!" Ron grabbed a wand and held it above his head. "A new wand! I finally have my own wand!!"

Willow wood, unicorn tail hair.

However, Grindelwald noticed the difference in Nietzsche's wand, but he only kept it to himself for the time being.

"How did you know we won the 700 Galleons jackpot?" George and Fred came over and immediately started showing off.

“Because no one knows a son better than his father.” Nietzsche pushed the two men away. “Look at you, you’re so tanned! You might as well live in Egypt… Your lottery win is on the front page of the newspaper!”

The Weasleys, you could say, are lucky despite their 'fools' nature.

However, more interested in Nietzsche than winning the lottery while on vacation in Egypt, George and Fred sidled up behind each other and whispered mysteriously, "Flying cars are all the rage now."

As they walked through the bookstore, the most frequent topic of discussion they heard was about magical cars.

Many wizards began to fantasize about owning one of these cars.

“My dad told me that several of his colleagues are secretly working on Muggle stuff,” Ginny whispered.
