Hogwarts: I am Harry's eldest cousin

"What I am going to teach you is not a simple Fiery Curse."

"It can be considered an advanced version of the Fiery Flame Curse. It is the result of my research that took me a lot of time to come up with - Blue Fiery Flame."

"In addition to being more malleable, it is also more stable and more powerful."

"Ordinary Fiendfyres can burn anything that can be burned, and they are endless. But these blue Fiendfyres can even burn ordinary Fiendfyres."

"Of course, the difficulty is also three times that of a normal Fiendfyre."

Grindelwald is a wizard who values ​​pragmatism above all else, so the content in his small classroom is basically all practical stuff. You must pay full attention, otherwise it will be a huge loss to miss any point. Don't expect Grindelwald to tell you a second time.

Just as he said, the difficulty of blue Fiery Flame is really extraordinary. Even with the help of Data Eye, Dudley failed to master the trick of changing the flame from red to blue in the first class.

"Bell, bell, bell"

Just as the class was about to end, Dudley's phone rang in his pocket.

The phone rang from Karkaroff, and Dudley answered the phone right in front of him without any hesitation.

Grindelwald and Dudley didn't communicate throughout the whole class, and Grindelwald was even too lazy to look at him. But from the moment the Den Den Mushi rang, Grindelwald's eyes never left Dudley. He waited quietly for Dudley to finish the call, and then took the initiative to say the first sentence of the whole class to him.

"A Muggle telegraph?"

Faced with Grindelwald's initiative to talk, Dudley naturally answered his doubts: "Professor, telegraphs are no longer used now. This is Den Den Mushi. You can also think of it as a mobile phone used by ordinary people. It is a communication tool that allows people to communicate freely even if they are thousands of miles apart."

"Phone? Mobile? Where's your phone line?"

There were no mobile phones in Grindelwald's time, but there were telephones, but they were the old-fashioned hand-cranked ones.

"No telephone lines are needed, biological signals are used."

Dudley didn't care whether he understood or not, and simply explained it to Grindelwald.

"Is this alive?"

After observing closely and seeing the human side of the phone bug, Grindelwald could not help but exclaim: "Have Muggles already developed such advanced technology?"

"Professor, Muggles don't know this technology. It's unique to wizards. To be more precise, it's my unique way of communication, and it's not widely available."

Dudley continued to explain.

"Not popular yet?" Grindelwald grasped the key words in the words very accurately, and a hint of ridicule appeared on his face unconsciously: "So wizards are still using that old-fashioned method of sending owls to convey messages?"

"Yes Professor, they thought it was convenient."

"Convenient?" The sneer on Grindelwald's face became more and more obvious. "The method of sending messages by owl is slow and time-consuming. It has long been outdated. Muggles can get the news in a very short time, but it may take us most of the day."

"Are telephones now common in the Muggle world, and the mobile phones you mentioned?"

In his time, telephones were still a rarity, but he firmly believed that after so many years, the world of ordinary people must have developed to an incredible level.

“As you might expect, most homes have access to telephones now, and even cell phones are not a big deal.”

Mobile phones had already appeared in 1983, the first meaningful text message appeared in 1992, and now it was 1995. The first "flip phone" Motorola 8900 was released, and Dudley happened to have a few of them. He planned to equip the discipline team with one.

"Such as this."

As he spoke, Dudley handed the latest model of Motorola to Grindelwald.

Grindelwald looked at Motorola carefully, his face full of surprise: "Incredible"

Soon he returned the Motorola to Dudley, found a seat and sat down, then said to Dudley, "If you don't mind, can you chat with me, an old man?"

"Let's talk about the lives of ordinary Muggles now."

Dudley was not vague at all. Since Grindelwald wanted to listen, he was willing to tell him about it.

It's funny to say that perhaps this 'dangerous dark wizard' who has been imprisoned for fifty years is the wizard in the entire wizarding world who knows best how powerful technology is.

He might be more sober than those half-blood wizards born in ordinary families.

So, with Dudley's vivid description, Grindelwald gradually revealed a side of the world of ordinary people today.

As Dudley began to tell his story, Grindelwald's expression remained calm at first, but when he heard that electric lights, refrigerators, and televisions had already become popular in the world of ordinary people, even he couldn't help but change color slightly.

"Muggle technology is just as good as magic, I knew it then."

"Tanks, missiles, and bombers can easily destroy the homes that wizards have worked so hard to build. As for the most dangerous weapons, most wizards cannot escape."

Even with Apparition, ordinary wizards would never be able to escape. The key to the door could work, but you had to know when the enemy would attack, otherwise it would be too late to run when the bomb exploded.

His period might be the only opportunity, but now, after more than 50 years of development, wizards... hehe

To put it bluntly, a sniper rifle headshot, even the most skilled therapist cannot save the brain that explodes like flowers from the sky.

After hearing the location of the Ministry of Magic base, Grindelwald didn't know what expression to use to describe his feelings at the moment.

"Built under a telephone booth."

"It really fits my impression of the stupid Ministry of Magic: arrogant, unambitious, and lost in the desire for power."

Grindelwald mercilessly expressed his complaints about the Ministry of Magic.

"You're right." Dudley agreed with Grindelwald's point of view: "If it weren't for this, Senior Tom wouldn't have almost overturned the entire wizarding world back then."

"I know him. He is a complete lunatic, but even I have to admit that he is powerful."

"He used very dangerous magical transformations to gain his current powers."

It is not surprising that Grindelwald knew the news about Voldemort. Don't underestimate any powerful wizard who stirs up the world. This so-called "prison" cannot hold him at all, no matter how strict the Austrian Aurors are in guarding it. The reason he is here is just because he wants to be here, nothing more.

The original book mentioned that Tom had experienced many dangerous magical transformations. When he reappeared, his appearance had changed drastically and he named himself Voldemort.

He sacrificed his looks for power, and he would rather be cursed than live forever.

Chapter 346 New Units of Measurement Launched

"Haha. Back then, the stupid Ministry of Magic and those stupid Aurors accused me of hating Muggles. In fact, I don't hate them. I have made speeches about this many times in public. Unfortunately, they didn't listen."

"But when faced with the mobs who truly hate Muggles, these so-called righteous people became a bunch of weaklings."

"Sometimes I can't help but wonder, did I not kill enough people back then? Or was my approach too gentle?"

One of the charges that the Ministry of Magic brought against Grindelwald was "hating Muggles and constantly causing killings", but in fact Grindelwald was not bloodthirsty. Although he did kill many people, he also admitted that he was not a good person. But compared with Voldemort, he was really much gentler.

However, in front of Voldemort, who truly hated ordinary people, half-blood wizards and was bloodthirsty, the Ministry of Magic did not even have the courage to convict him. For the past ten years, they have only called him a mysterious man.

Perhaps Grindelwald's actions can be considered as belonging to the lawful camp after all. Their style of doing things is more or less traceable, and as long as they are not interfered with, they will be fine. Voldemort, on the other hand, belongs to the chaotic camp without much logic, and everyone is afraid of the chaotic camp because they don't care too much about killing people.

The two chatted from eleven o'clock in the evening until late at night (Harry went back to rest early halfway through the conversation), and finally Grindelwald let out a long sigh.

“The future belongs to you young people”

"We old folks will eventually be eliminated by the times. All I can do is pass on my knowledge to you as much as possible."

“Thank you for talking to me for so long.”

"But don't be late tomorrow."

Dudley said goodbye to Grindelwald respectfully and left, leaving Grindelwald alone in the room.

After sitting there blankly for a while, Grindelwald stood up and was about to leave. At this moment, his body suddenly paused, and his eyes, which had originally recovered, turned a strange color again.

He knew that this was the moment when the prophecy came true.

As expected, countless intermittent fragments of images flashed before his eyes, as if he had captured the trajectory of the future.

But what puzzled him was that the future he saw this time was completely different from the two futures he had seen before. It was a completely new future.

Is there a third future?

what is the problem?

Why are different futures emerging one after another, and nothing like this has ever happened before.

With such doubts, Grindelwald saw the protagonist of this prophecy.

The pupils in his eyes contracted slightly.

'It's him! '

Time passed like water, and in a blink of an eye the vacation was about to end, and no one present was eliminated.

Due to the Austrian Ministry of Magic's "tight defense", the owls responsible for delivering the letter (fifth grade shopping list) could not enter at all, and had to be delivered by Dumbledore. This was the second time that Dumbledore took the initiative to appear in Nurmengard Castle.

Grindelwald sat on the steps of the stairs as usual, looking at the people below and said: "Although your knowledge, magic, and practical experience are far beyond that of ordinary adult wizards, and are stronger than most of those useless Aurors."

Grindelwald never forgets to DISS the Aurors, and his resentment towards them is profound.

Then his tone became more serious: "But these are just the beginning. To the truly powerful wizards, you have only just stepped into the realm of magic and are still very immature."

“Never become complacent with just a little bit of success, and always maintain the utmost respect for magic.”

"Remember, the path of magic is endless."

Grindelwald's farewell was very plain, he just said a few simple words and that was it.

"Dumbledore, if possible, let them come over next holiday."

Grindelwald's voice rang in Dumbledore's ears, who still had his back to him.

The wizarding world also has methods of transmitting information without speaking, but the distance cannot be too far, and ordinary wizards cannot learn it.

"It seems you are quite satisfied with them."

Dumbledore replied, still showing no intention of turning back.

As for the Austrian Ministry of Magic only allowing one week, their opinion is not really important, but we still have to ask for courtesy.

If Grindelwald sent another note, they would definitely agree.

Otherwise, once Grindelwald escapes from prison, it will be a time for a large-scale "reshuffle" of Austrian magic. For the sake of the hat on their heads, they will also meet any needs of the other party.

"There are three little guys who are really interesting."

"Dursley, Potter, Granger?"

"No, it's Dursley, Potter, and Longbottom. Of course, Granger is also very good, but she is more talented in spells and is not very suitable for my system."

Dumbledore was more or less surprised by the answer given by Grindelwald.

Although Longbottom is excellent, he cannot compare with Granger. In terms of grades, Granger is only second to Dudley. Even she herself thinks many of her papers are good. Professor McGonagall dotes on her as a student and almost regards her as her successor.

In comparison, Longbottom's performance in all subjects could only be considered excellent, at best at the level of Cedric. However, he was good at Herbology, and Pomona (Headmaster of Hufflepuff House) had mentioned to him more than once that Longbottom should be transferred to another house.

Well, excellent.

New unit of measurement is online - Cedric.

"Albus."

If it was Dumbledore when the relationship had just broken up, he would definitely not agree to the other party calling him like that, but it doesn't matter now.

When Dumbledore's name was called, Grindelwald fell silent, and he did not speak until Dumbledore left.

He was worried or even afraid that if he said it out loud, it would not be allowed.

This is about the third future.

Before leaving, Dudley walked up to Grindelwald and took something out of his pocket. It was a silver-white Den Den Mushi. Unlike the other Den Den Mushi that were either dozing off or sleeping soundly, this one had a pair of big, bright eyes.

"Professor, this is for you."

When the Den Den Mushi was handed to Grindelwald, the Den Den Mushi stared at the other party curiously with its big eyes.

"What are you giving me this for?"

“It’s convenient to contact.”

"If I encounter any problem I don't understand, I can always ask you for help, right?"

'You must be joking. You never stop asking questions.'

Just as Grindelwald was about to say something to refuse, Dudley made an offer he couldn't refuse.

"There's one in the principal's office, too. It's gold."

"This makes communication very convenient. It's much better than using an owl or something like that."

What else could he say?

Of course I accepted it silently.

If nothing else, answering students' questions is a professor's basic responsibility.
