Since buying books and buying houses, during this time in this world, Ning Yuan and this local snake have also made a lot of transactions, and although the relationship between them is not as close as that of the table, it can be regarded as an exchange of interests.

Buy all kinds of magic materials, buy all kinds of alchemy items, and so on and so forth! It can be said that in this world, Ning Yuan used his inexhaustible gold to give the natives of the wizarding world an image of being wronged.

If it weren't for the support of the Avery family, as well as the "relative" relationship with Dumbledore, someone would have come to pinch Ning Yuan's soft persimmon a long time ago.

Just because the other party did not cross the river and demolish the bridge, and blocked a lot of secret troubles for him, whether it was because he was afraid of Dumbledore, or hoped to get more benefits from Ning Yuan, Ning Yuan was still very grateful to Cromwell, so he gave almost all the business to the other party.

The good news he brought to Ning Yuan this time was that the house-elf that Ning Yuan had always wanted had found a so-called aristocratic family that was willing to sell.

Although the pure-blood families in the hp world are called pure-blood nobles among various fandoms, after coming to this world, Ning Yuan realized that wizards who have never urinated with Muggles, even legends such as the Hogwarts Big Four do not have the title of Muggle world, not to mention that other histories may not be as good as the pure-blood families of the Big Four families, so Sirius in the novel will say that there are no nobles in the wizarding world.

However, even so, in the context of faintly respecting pure-bloods, pure-blood families undoubtedly have the arrogance and conceit peculiar to nobility.

It's like the Gaunt family described through Dumbledore's memories in the novel, obviously down to the same level as beggars, but still holding the pride inherited from the Slytherin bloodline, even if the poor family is surrounded by walls, they are immersed in the so-called family glory, thinking that they are superior, and gradually drowning in it.

The house-elf is undoubtedly a symbol of a pure-blood family, if it is a private property like the village of Hogsmeade 34, there may be people who are willing to sell it secretly when life is difficult, but it is difficult to meet someone who wants to sell the elf.

As a house-elf that is only possible in an ancient pure-blood family, it has been branded as a pure-blood from the beginning, just like the face of a family, and it is unlikely that anyone will want to sell it.

So after learning the value of this thing, Ning Yuan didn't have much hope, who knew that now the good news is one after another, someone is actually willing to sell a house elf.

Even if the price Cromwell said in the letter was a sky-high price in the eyes of many people, Ning Yuan would not care too much about the amount of gold that was no different from stones piled up in his personal space.

So he immediately wrote back to Cromwell, telling him that he was willing to buy the house-elf.

Soon, Cromwell came to the door.

"Ning, you're really crazy, you're willing to spend so much money just to buy a young female house-elf!" Looking at the gold that had been prepared, Cromwell looked at Ning Yuan with the eyes of a monster.

Ning Yuan spread his hands, "Karen, for me, money is not a problem, as long as I can buy what I need, I am willing to pay no matter how much money I have." You know, it's hard to find someone willing to sell a young, strong, magical female house-elf. ”

"Well, you'll get what you want in two days." Cromwell was apparently only paying lip service to how he could have given up on this lucrative deal.

After his invisible agent Cromwell left with the gold, he put away the excitement in his heart, and Ning Yuan had time to experiment with his new wand.

"Yugadim, Leviosa!" With a wave of his wand, watching the feathers on the table slowly float, Ning Yuan's heart was full of excitement.

He may have experienced alchemy and ancient magic, but it was all thanks to Dumbledore's aid, and now it was the first magic he had performed in the almost two months since he came to this world, which was of great significance.

Ning Yuan, who had already learned theoretical knowledge, was now very easy to get started with simple magic, because he already knew the key points of various spell casting, and now Ning Yuan had to do only to combine theory and practice.

After trying a few more first-grade compulsory spells, Ning Yuan was relieved to see that his "lying salary and tasting guts" had worked, and through the magic wand, his control over his huge magic power that had skyrocketed in just two months, and was already faintly out of control was very high, not to mention the smooth use of various spells, and he was also very handy at mastering the power of spells.

"Sure enough, sharpening the knife is not wrong for the woodcutter." Ning Yuan waved his crystal wand in relief, and the large and small things in the room floated, like a galaxy model, circling around him.

Ning Yuan made up his mind that after the transaction of the house-elves was completed, he would have to "retreat" for a period of time, and transform theory into strength, which was the only purpose for him to come to this world.

Anyway, Dumbledore also knew that Ning Yuan's role was dispensable, so he didn't want to get involved in the end-of-semester carnival that Dumbledore had prepared for Harry and Voldemort.

A few days later, Avery came to the door with a young house-elf. After handing over the formalities and the magic contract, Avery rejected Ning Yuan's invitation to dinner and left in a hurry.

"Your name!" Ning Yuan is not a slave owner, but judging from the temperament of the house-elves in the original plot, except for Dobby of the Malfoy family, the other house-elves are the kind of servile species, and they enjoy being enslaved.

"My name is Sasha, master!" Sasha was small, with bat-sized ears, protruding eyes the size of a tennis ball, a long, flat nose, and wrinkled skin.

Aside from the fact that he had been given a decent simple outfit for changing into his owner, the elf looked even thinner and miserable than his kind, and there were many scars on his exposed skin.

It seems, as Avery said, that her former owner was a grumpy loser with no grace.

"Alright, Sasha, take a look at these recipes and learn to make them later!" Ning Yuan threw a Chinese recipe to Sasha, he had had enough of the dark cuisine of England all this time, and now he had a ready-made hard-working servant, how could he still let his stomach suffer. "Then, now help me clean this house properly and check for safety hazards."

"Yes, master!" With a crackling sound like a firecracker, Sasha snapped her fingers excitedly as if she had been greatly encouraged, and disappeared in front of Ning Yuan.

Sure enough, it is a deep servility, and it is the pursuit of life to be enslaved, and you can see this somewhat distorted value by looking at the disgust of Dobby, the only one who made a "declaration of freedom" in the original book.

Thinking about it, Sasha probably doesn't have much work to do in the declining pure-blood family, so she will be so happy after getting the task of the new master.

"Then we have to wait for next year's Dobby!" Ning Yuan has already made a plan, and when the secret room opens next year, he must fool Dobby to work for himself, and then he will have a female and a male, and he can reproduce more high-quality servants.

"Besides, if you train well, the magic ability of house-elves is even stronger than that of ordinary wizards." Imagining Sirius, who was pitted by house-elves in the original book, and even Voldemort, Ning Yuan guessed that if someone could secretly form an army of house-elves and then configure wands for them, then it would probably not be impossible to conquer the current wizarding world.

In the fourth novel, Twilight is questioned about using Harry's wand to create a Dark Mark that house-elves can indeed use wands.

This kind of species that is loyal to its master does have great plasticity, and it also plays a very big role in Ning Yuan's future adventures in time and space.

Even in the HP world, the various apparition restrictions of humans do not have any restrictions on house-elves, Kreacher can apparilate at an important place where Voldemort collects Horcruxes, and Dobby can apparilate freely at Hogwarts, if used well, it can play a big role.

Therefore, this is the reason why Ning Yuan wants to get a house-elf.

It's just that after learning about the abilities of house-elves, Ning Yuan can't turn a deaf ear to the threat of house-elves like a local wizard, and now that the Malfoy family has a Dobi, who knows if there will be other house-elves determined to find freedom in the future, he is determined to give the other party more restrictions, at least so that she can't betray herself.
