"It turns out that pure-blood families all call each other by their full names? Mr. Lucius Malfoy. ”

Karn followed Lucius as he learned to pronounce his full name, then patted Hermione's shaggy hair and continued to speak to Lucius

"Dragon's blood pastries don't seem to be selling much lately, my goddaughter used to like them, but unfortunately she can't buy them, Mr. Malfoy, do you know what's going on?"

Hermione was stunned for a moment, but she was smart enough to cooperate with Karn and said to Lucius, "Yes, Mr. Malfoy, I love dragon's blood pastries..."

After saying this, Hermione remembered what the dragon's blood pastry was, Phil had brought it to her once, but not only did she vomit it herself, Hermione also saw her Karn godfather also have a painful face after eating it.

It's a thing that only freaks love to eat.

Lucius exhaled deeply, a large part of the Malfoy family's business was related to fire dragon materials, but because of Karn's methods, the business could not be done, and the family's income was reduced by a large margin.

He lashed out at Karn in the Daily Prophet, in large part because of it; Lucius even tried to lobby the Ministry of Magic, and he was not the only one who did it, many Potions families in Europe lobbied the Ministry of Magic.

However, the Romanian dragon training farm and Kahn have a trade contract that will not be easily terminated.

"Pure-blood families don't fall so easily, Mr. Pente."

After Lucius said this, he called out to Draco to squeeze through the crowd and walk outside.

Karn shook his head, if the pure-blood family didn't value bloodlines so much, there would have been a possibility of cooperation between them; As long as three or four pure-blood families were gathered to obtain money and power, it was easy for them to monopolize a few magical items.

And the profit is the most motivating one's heart, as long as the benefit is big enough, three hundred wizards can be gathered together to cast the Avada Suo curse on Voldemort.

"Hello, Mr. Pente, I'm Arthur, Arthur Weiss is here."

Arthur Weiss came to greet Karn after Lucius had left, and then whispered, "Thank you for the Prison Spell, Professor Pent. ”

Karn chuckled, "It's nothing, I don't like that guy either. ”

While Karn was talking to Arthur, Hermione also found her friend and asked, "Harry, Ron, were you all right just now?" ”

"Alright, Hermione, is that your godfather?"

Harry Potter thought for a moment and continued to ask Hermione, "He should be the professor of our new Defense Against the Dark Arts class, I read about him in the Daily Prophet." ”

At Wes's house, Harry was curious about what was going on in the wizarding world, so he read the previous Daily Prophet.

"Of course, the Godfather is very powerful, Harry, you can learn from him when school starts, except for Dumbledore, I have never seen a wizard as powerful as the Godfather..."

The excitement on Hermione's face was like preaching, in every sense of the word.

It turned out that when Karn didn't know magic, Hermione only respected and relied on Karn; But seeing Karn's level of spellcasting and learning anything as simple as drinking water and eating, Hermione's feelings for Karn turned to reverence.

And the godfather was very kind to her, and when Hermione told her roommates about her life with the girls of the wizarding family, they didn't believe hermione, thinking that Hermione was lying and bragging.

That kind of life, even in pure-blood families, is relatively rare, not to mention that Hermione is from a Muggle family.

Ron was a little incredulous, and said with a strange expression on his face, "Is it that powerful?" I think he's young..."

"Ron, you haven't seen anything great about Godfather Karn, but when you get to Hogwarts, you'll definitely have plenty of opportunities."

Hermione raised her head slightly, although she didn't like people to question Karn, like those thrashers in the Daily Prophet, she believed that Ron was also influenced by these people, but after spending some time with the godfather, she could find out how powerful he was.

"Hermione, do you want to talk for a while?"

On the other hand, Karn had already finished talking to Arthur, but there was nothing to say, Arthur liked Muggle things, and Karn didn't want to talk about some issues that were considered common sense among ordinary people.

"That's all it takes, Godfather, and we'll talk about the rest when we get back to Hogwarts." Hermione trotted over to Karn, she still had something to sell.

However, after meeting Arthur, Karn remembered one of the most important technologies in the wizarding world, and that was the magic modification item.

Arthur's modified car was a very common alchemy method, and Karn valued the elf's alchemy process more; Until now, there are still many alchemy products made by goblins, and wizards can't crack them.

The basilisk in Hogwarts was also valuable, and Karn only remembered after he had left, that he had forgotten to take the notebook from Ginny's hand.

Once at Hogwarts, Karn also planned to get the Vanishing Cabinet in his possession in the Room of Requirement, so that he could travel between Hogwarts and Diagon Alley; After all, the business is still in its infancy.

In the European wizarding world, the need for dragon materials and magic item materials has always been the most in demand, and Karn can occupy the entire European market with the exclusive sale of dragon materials.

In fact, Karn had already done so, and the difference between the purchase price and the sale price of the magic materials in his shop was 1.5 times, and he had only changed hands, earning more Galleons than those men had worked so hard to cultivate herbs.

After shopping, Karn asked Hermione what she wanted to do, and once he went out, he accompanied his goddaughter for a good stride.

..................

When it was time for school to start, Karn didn't ride the Hogwarts Express with Hermione, he arrived at the school early to familiarize himself with the environment.

Otherwise, by the time the first day of class came, Karn would be disgraced if he got lost in the castle.

"Professor Pent, welcome to Hogwarts."

When Karn arrived, he was greeted by Dumbledore himself, and in addition to Dumbledore, there were Professor McGonagall, the cat lady who had met Karn twice, and Professor Snape, a greasy-headed professor.

"Professor Dumbledore, I'm glad to be teaching at Hogwarts, I've done a lot of preparation to be a good Defence Against the Dark Arts teacher."

Karn smiled back and said that he had gotten to know all the professors at Hogwarts after being introduced by Dumbledore.

However, when Dumbledore introduced Snape, Karn somewhat regretted that he hadn't learned the art of reincarnation in the dirt, otherwise he would have done business with Snape.

There was still a day left before the new students entered the school, so Karn, led by Filch, took Hogwarts around and set up his own office; The garlic Quirrell seemed to have left in the house, Karn magically cleared all the corners.

Forbidden book area, responsive house, forbidden forest.

Karn was intrigued by all three places, and he felt like a freshly entered student, curious about all of them.

Defence Against the Dark Arts professors have their own bedrooms and can also sleep in the office, which has a space to rest next to it.

Karn didn't hold back, and went to the library that night, although he was curious about the dark arts in the forbidden area, he knew too little about magic, so he wanted to read more books about magic in the library and then go to the forbidden area.

As long as Mrs. Pacings said it, Karn could stay in the library for a night, and only the professor had that power, and if he were a student, he would definitely be kicked out.

Karn usually used to read books in shadow clones for the sake of efficiency, and with his memory he could withstand the memories transmitted back by four clones, and he only picked books on magic to read.

The shadow clone combined with his super memory allowed Karn to read more than a dozen magic books in a single night and memorize all the contents of them, which is unimaginable for the average wizard.

It was just before dawn that Karn put down the magic book in his hand, put it in order, and disarmed the shadow clone.

In an instant, the vast memory and chakra returned to Karn's body, his eyes glowing with a fiery red, and it took two or three seconds for him to recover.

"Whew, it's a real headache, it looks like I need to sort out my memory...."

Karn rubbed his head, remembering it all, but he needed to sort out the memories in his head before he could make sense of what he had seen.

"Magic is really a magical power, as if it can touch the realm of particles with magic power, disrupt and reassemble and deform... If you can do all of the above, why is there a basic law of Gamp transformation?"

Karn didn't understand, he knew not only magic, but also chakra; Magic seems to follow the principle of equality of exchange, and while otherwise useful, it is not possible to create items out of thin air and keep them.

Chakra is different, there is a big difference between the two.

Karn thought for a moment, then shook his head and stopped thinking about it, "Now learn some powerful magic, and as for the principles of magic... It's not that far. ”

As his strength grew, Karn could observe.

During the day, Karn did not go to the forbidden area, but took advantage of his wandering around the castle to go to the Room of Requirement and find the Vanishing Cabinet.

As a trustee and professor of Defence Against the Dark Arts, Karn didn't think it was too much to give himself a back door to go home.

As it gets dark, it's almost time for the new students to enroll.

By the time Karn arrived in the Great Hall, Dumbledore and the other professors were already seated; Upon seeing Karn, Dumbledore reached out and gestured to the location next to him, indicating that it belonged to Karn.

Not long after Karn sat down, students walked into the Great Hall one after another, and he saw Hermione, smiled and waved at Karn as he entered, and then sat down with Ron and Harry Potter.

Karn was a little surprised to see the two people next to Hermione, he remembered that the two of them should have been stopped by the Malfoy house-elves from coming to Hogwarts, and then came in Arthur's modified car, how did they change again.

The sorting ceremony was soon over, and after all the young wizards were seated, Dumbledore stood up, ready to announce a few things before dinner.

"Quiet."

After all the young wizards had quieted down, Dumbledore continued, "I discussed with Professor McGonagall that the school is planning to replace with some new broomsticks, as some of the old broomsticks have a long history and pose a risk to our Quidditch trainers. ”

"The greenhouse is also going to be expanded, and this matter is being watched by Professor Sprout, but her herbal medicine class needs to be changed with other professors until the greenhouse is expanded."

"And Mr. Filch has proposed seventy-three more contraband items to me, and I have agreed to all of them, and the list will be published by Mr. Filch."

"Finally, we're going to have a new Defence Against the Dark Arts teacher, Professor Pente."
