"As the most prestigious wand-making family in the UK with a long history.

The ancestors of the Ollivanders family first migrated to England from the Mediterranean with the Romans, and in 382 BC set up their first stall in Diagon Alley, the settlement of the English wizarding world, to sell wands to the English wizards of the time. ”

Clark's voice is unhurried, with a unique charm that makes one can't help but fall into it, and along with his words, immerse yourself in those stories.

"And Mr. Garrick Ollivander is the representative of this family in today's wizarding world, as a master wandmaker, he has successfully improved the wand making technique, researched various wand body and wand core material combinations, and also mastered the occult skills that allow wizards to establish communication with wands, which makes his wands more powerful and more closely related to wizards."

It turns out that before Ollivanders took over the family business, wizards used a variety of wand materials. Like a cat's whiskers, white fresh branches, or the hair of a mermaid that a customer picks up by chance.

They tend to give their preferred or ancestral magic materials to wand makers and let them make wands based on these materials.

However, most people don't know what they need, and it is difficult for them to recognize themselves, so they can only go with the flow, so their wand materials are strange, and the wands they make have their own characteristics.

Some wands may be extremely powerful, but more often than a wooden stick is not much stronger, and even some wands are counterproductive, not only not helping young wizards channel their magic, but also suppressing their magic.

Ollivanders changed all of this by boldly choosing powerful magical materials such as unicorn tail hair, phoenix tail feathers, and dragon nerves as the core of his wand, and choosing a variety of woods to match them, forming a distinctive standard wand that can be suitable for people with different personality traits.

It is precisely because of the improvement of the cane-making technique that the demand for dragon materials has greatly increased in the Orlivander family, in addition to the dragon nerves as the core of the staff, there are also dragon blood, dragon bone powder and dragon glue.

Soaking liquids like wand core materials, especially dragon heartstrings, use dragon blood, which can keep the wand core material alive.

So the entire Ollivanders family has developed to the present, not only a wand shop, but also involved in the production and sale of wand maintenance tools, the pretreatment of magic wood, and the production of alchemical items related to dragons. Clarke's duel wand protector tied to his wrist is a product of their family.

When mastering the processing in the middle of the industrial chain and the sales in the downstream, the Ollivanders family naturally also has some bargaining power, and has reached a close cooperative relationship with the dragon family in Eastern Europe.

Clark's words directly revealed the hidden forces behind Ollivander, the master staff maker. In addition to this family, the other three families are also not simple.

"Karaktakus Bock, or Bogin Bock, his shop is famous in the underworld, and the entire Bock family has become the largest black market smuggling family in the wizarding world because of his existence.

As long as you have enough gold gallons, you can buy all kinds of forbidden items from the Ministry of Magic, as well as all kinds of evil dark magic items.

Among them, the smuggling and transportation of the dragon's raw materials is also in charge of their family. ”

"The Slughorn family is similar to the Ollivanders, except that one of them uses the materials on the dragon's body to process and produce alchemy items, and the other produces magic potions."

Saying this, Clark suddenly turned his head to look at Harry: "Harry, I remember that you have been reviewing recently, tell me, among the twelve uses of dragon blood, which ones involve the preparation of potions?" ”

Harry was stunned for a moment when asked, and said hesitantly, "The second use of dragon blood, part of dragon blood can be used as an external medicine, and the strong vitality contained in the blood makes it have a certain healing effect. ”

"The third use of dragon's blood can be used to prepare powerful healing potions."

"The fifth use of dragon's blood can be used as a base solution for mana boosters."

"The sixth use of dragon's blood is the main material for the preparation of skin sclerosing agents."

He spoke more and more slowly, and finally stopped, and Clark asked, "Is that all?" What else? ”

"And ......," Harry turned his eyes to Hermione, who told him righteously, "and the seventh use, which corresponds to the sixth, as an adjunct to skin softeners." ”

"But you're not telling you all about it before," Hermione added to him, "Although dragon's blood can be used as an external medicine, the dragon's blood of the Welsh green dragon is poisonous, and its dragon's blood cannot be applied externally. ”

"The third use is already a relatively old formula, and now potions masters generally prefer to replace the vitality effect of dragon's blood with relatively mild potions. In addition, the mana booster in the fifth use, which only fools would drink, has so many side effects that it is not very popular now. ”

"Smack, smack, smack." Clark applauded Hermione's answer, "Yes, all right. However, even the potions refined by the dragon have various negative effects, but its advantages are also extraordinarily prominent, with fast and strong effects. The British wizarding community has been at peace in recent years, but in other turbulent places, these magic potions are still in good demand. ”

"As for the last Crouch family, they are the key to the entire British dragon chain. You don't think that the Ministry of Magic is really indifferent to this huge industry that involves hundreds of thousands of gold gallons.

As the director of the Department of International Magical Exchange and Cooperation of the Ministry of Magic, Barty Crouch is in charge of negotiating with the Ministry of Magic in Eastern Europe, and it is with him and his family that the other three families will not be wiped out by those foreign dragon families. ”

These four families are responsible for the production, sales, logistics and most importantly official communication of Julong Materials in the UK.

Coupled with some new wizard families similar to the production of stove cleaners, they have woven a large network of industrial chains, earning huge wealth while also restricting the development of the country's dragon breeding industry.

"Since they are so powerful, why don't they leave those wizarding families in Eastern Europe behind and raise dragons themselves?" Malfoy asked, a little puzzled.

He had also asked his father to build a dragon farm in his home, but his father refused.

Clark glanced at him, and was going to mock him for being too shallow, but after thinking about it, he felt that this was normal.

If it weren't for the insight he had gained from the information explosion in his previous life, I'm afraid his thoughts would not be much different from Malfoy's.
