In any place with an open market economy, it's quite challenging to form a regional sales monopoly.

Because all replicable commercial activities will inevitably lead to market competition. Human beings' innate learning and imitation abilities are clearly demonstrated in this regard.

Even in the relatively small Diagon Alley, these competitive rules apply. For example, there are three clothing stores alone: Twilfitt and Tattings, Madam Malkin's Robes for All Occasions, and the second-hand robe shop. When wizards want to buy magical creatures, potion ingredients, or even various newspapers and books, they often have more than one option.

If you include the shops in Knockturn Alley next door, this market competition becomes even more obvious and intense.

However, there are two industries that are exceptions.

One is the large global chain bank Gringotts, completely controlled by goblins.

The other is the wand shop run by the Ollivander family, who have been making wands since 382 BC.

The long family tradition and the spread of word-of-mouth have given the Ollivander family a very high position in the wand-making world.

Especially Garrick Ollivander, the heir of this generation, was influenced by the wand-making techniques passed down through generations in the family, and he showed his talent very early on.

With the ambition to improve the wand cores and woods currently in use, and resolutely and fanatically pursuing the ideal wand in his youth, he quickly became one of the three major wandmakers in Europe, and is known as the best wandmaker in the world today.

As a result, many foreigners come to London specifically to buy a wand made by Ollivander, rather than buying one locally. Naturally, Ollivander's Wand Shop completely monopolized the wand business in the London area.

Having finally entered the magical world, Eileen was naturally full of expectations for her future wand. What she said before about not wanting one was just a fit of pique.

"This is Ollivander's Wand Shop? The legendary best wand shop in the world?"

Eileen looked at the small and shabby shop in front of her with some uncertainty. If it weren't for the gold-lettered sign on the door, which was peeling off, clearly stating: "Ollivanders: Makers of Fine Wands since 382 B.C.," she would have even suspected that Dumbledore had taken her to the wrong place.

"The value of something is not always matched by the splendor of its appearance. Ollivander is a pure wandmaker. For him, spending a Galleon on anything other than wands is a shameful waste."

Dumbledore smiled gently and led Eileen into the small wand shop.

The shop was small, with nothing but a long bench, and thousands of narrow boxes containing wands were stacked almost to the ceiling.

"Dumbledore? Albus Dumbledore! It's so good to see you again! Welcome, welcome, I didn't expect you to come."

Before Eileen could see the wand boxes around her, an old man suddenly stood in front of them, his light silver eyes like two shining moons in the dim shop.

Ollivander showed obvious joy at Dumbledore's sudden visit. The old man walked up to Dumbledore, rubbed his palms, and his tone was slightly cramped and excited.

"Mr. Dumbledore, you must have that wand with you, right? Could you let me study it? I can agree to any request you have."

"Ollivander, we'll talk about that matter separately later."

Dumbledore raised his hand slightly, stopping Ollivander's subsequent words with a look in his eyes. He reached out and pulled the silver-haired little loli standing behind him in front of him. "She's the protagonist today."

"Oh, of course, yes, yes." Ollivander cautiously stopped the topic, turned his head and looked Eileen up and down.

"Very strange, quite strange. I feel an extraordinarily willful and exceptionally powerful wandering magic."

Ollivander murmured softly, his silvery-white eyes making Eileen's hair stand on end. The old man's dry fingers gently stroked Eileen's silver hair hanging over her shoulders, and a meaningful and strange smile appeared on his face.

"Mr. Dumbledore, according to the Wand Regulation, magical creatures are not allowed to have wands, you know."

"Thank you for the reminder, I am well aware of the contents of the Wand Regulation. Miss Eileen Kaslana is a genuine human wizard, but she has some unique talents."

Dumbledore said with a serious face, which was another reason why he insisted on accompanying Eileen to get a wand - as a Veela hybrid, Eileen's bloodline concentration was too high.

If it were an ordinary wizard, they might just think that this little girl has extraordinary magical potential. However, facing Ollivander, who spends almost his entire life dealing with magical materials, Eileen has no way to hide it.

"I heard that Hogwarts is the only place in Britain that has successfully tamed Thestrals..."

Ollivander suddenly said something out of the blue.

"In this regard, I don't think there should be too much problem." Dumbledore smiled slightly.

"Well, an excellent little wizard."

Mr. Ollivander's brow loosened, glanced at the silver-haired little loli standing in front of him, and moved his finger away from the girl's silver hair. "Alright, Miss Kaslana, come on. Let me see." He took out a long strip of measuring tape with silver scales printed on it from his pocket. "Which arm are you used to using?"

Eileen didn't answer directly, frowned and asked, "It's just buying a wand, why do you need to measure my body?"

"Because every wand in the Ollivander family is unique. In order to help you choose the right wand, I must first measure the length of your arm, forearm length, height, head circumference and other dimensions, and then select the wand based on these parameters."

Ollivander, who had just received Dumbledore's promise, was obviously in a good mood, smiled, and patiently explained to Eileen.

"But, I'm only ten years old now. I'm going to grow up, right?"

After hearing Ollivander's explanation, Eileen became even more puzzled, shook her head and asked confusedly, "The data you measured will be meaningless after a year. Wouldn't I have to replace the wand every year?"

"Uh..."

The smile on Mr. Ollivander's face suddenly froze, the corner of his mouth twitched, and he didn't know how to answer. Over the years, he had never thought about this issue before.

"According to your theory, if a child who is 1.2 meters tall uses a twelve-inch wand, then when he becomes a two-meter tall man, he wouldn't still use such a small wand, right? If it increases proportionally, he would have to change it to a club as thick as a wrist, right? The magical material inside should also be increased, right?"

Eileen tilted her head, gesturing with her fingers. For wand, a casting tool that can be regarded as a weapon, Eileen has always had such doubts. As an important existence that enhances the effect of magic, the weapon of an adult wizard should be bigger, thicker and more powerful - even if it is not a two-handed staff or the like, it should at least be like a rolling pin, right?

"The strength of a wizard will improve with age and knowledge, so why doesn't the wand upgrade with the improvement of strength?"

Boom!

Faced with the naive question from the little girl in front of him, Ollivander suddenly felt a door that had been imprisoning his thinking open with a bang, and a whole new world of wand-making appeared in front of him.

Before that, he had been trying to change the wand material and the combination of different wand cores, and once thought that that was the future direction of the wand business reform, but he never considered changing the form of the wand in essence.

"...You have a point."

Mr. Ollivander opened his mouth with difficulty, his expression became extremely solemn, and he answered with a dry voice.
