Albert knows nothing about the meeting between Dumbledore and the Le Mays. He is now madly absorbing the knowledge of alchemy mentioned at the party.

This time, it really came right.

Although everyone did not fully disclose their results, Albert still learned a lot of useful things, which can be described as a huge gain, directly reflected in the skyrocketing experience of alchemy skills.

Moreover, most wizards are willing to maintain owl contact with him. Albert naturally refuses to come, but he is very strange, when did he become the sweet bun in everyone's eyes?

Are they very optimistic about their future?

Albert quickly got rid of the extra thoughts in his mind and listened carefully to Adolf's explanation of the important principles of double-sided mirrors.

In fact, the double-sided mirror is not a secret in the magic world. However, the double-sided mirrors that were popular in the magic world have basically disappeared from the market.

"I have a question!" Albert waited until Adolf finished speaking and asked his doubts, "Why are there basically no people selling double-sided mirrors now?"

"Mr. Anderson, as I just said, the manufacturing process of double-sided mirrors has disappeared for many years." Adolf said regretfully.

"Actually, many people know the general principle of this magic mirror. However, after the death of its maker Blair Bosd, the technology to make double-sided mirrors disappeared, and no one can create Blair. Burst's double-sided mirror is gone."

"As I said, double-sided mirrors were once popular in the magical world. At that time, there were still a large number of double-sided mirrors in the magical world. No one would make inferior products because they couldn't sell them."

Later, with the damage of the double-sided mirror, the remaining quantity decreased, making it difficult to find double-sided mirrors on the market, and the manufacturing technology of double-sided mirrors has gradually been forgotten by people. Of course, the most important thing is Another point is that if you want to make a double-sided mirror, you must be proficient in both alchemy and transformation spells.

The essence of the magic mirror of the double-sided mirror is the advanced application of the change spell. However, there are very few wizards who can use it on the magic mirror.

Even if you are proficient in alchemy and change spells, you can successfully create a double-sided mirror. However, the magic released on items will weaken over time.

There is no such problem with the double-sided mirror made by Blair Bird. No one knows the secret of it.

"This is not surprising. Many ancient crafts have been gradually lost or eliminated by the times, just like the vanishing cabinets that were popular in the First Wizarding War."

"No, sir, I think many people are mistaken." Albert reminded kindly, "Actually, double-sided mirrors are still very popular. Take a couple of my friends at Hogwarts as an example. After graduating from Hogwarts, they definitely need a double-sided mirror to keep in touch. This method is much faster than writing letters. What do you think?"

At this moment, everyone present was stunned, and then someone couldn't help but laughed and nodded and said: "You are not wrong at all, but our old men have rigid thinking."

Families can use double-sided mirrors to communicate with Hogwarts children, and couples can also use double-sided mirrors to communicate, just like video calls, but many people don't think of this.

"Mr. Anderson, you seem to be very interested in double-sided mirrors?" Adolf asked curiously, "Can you tell me why?"

"I think this technology is very promising." Albert explained, "If I have a double-sided mirror, I can keep in touch with my family on time every week instead of writing letters. If we have a double-sided mirror, If you want to talk about some alchemy topics, you don't need to write letters. Although owls are convenient, they take time to communicate, and letters sometimes do not perfectly express one's thoughts."

"In the Muggle world, there is something called a telephone, which allows people in two places to communicate with each other through words, and the technology of the double-sided mirror obviously goes a step further and narrows the distance between the two sides."

"Great idea." Adolf applauded. "If you want the knowledge of double-sided mirrors, I don't mind sharing my research with you. Maybe one day you can invent a better magic mirror. Don't forget. Please write my name together!"

Everyone couldn't help laughing when they heard the last sentence. They also knew that this was just a joke, and the wizards here didn't care much about the fame and fortune, because they were so famous in the magic world.

"Thank you for your generosity." Albert bowed slightly to the old wizard. "If one day comes, I will."

At this moment, everyone was quite surprised. They didn't understand why Albert was optimistic about the double-sided mirror. Although they heard Albert talk about the reason just now, they still didn't understand.

Magic is very convenient. Wizards rarely have a sense of distance. If necessary, a phantom manifestation or Floo powder can reach the destination in no time.

This is also one of the reasons why the double-sided mirror is gradually eliminated ~ www.mtlnovel.com ~ people no longer need it.

However, such a technology still has many uses in Albert's eyes. It can only be said that there is a certain gap between the thinking modes of the two sides.

Albert glanced at his task panel.

Missing technology.

You came into contact with the knowledge of double-sided mirrors and became interested in it. However, you have been aware of this technology for many years. You retrieved this technology and recreated a pair of double-sided mirrors.

Reward: 10000 experience, 1 skill point, double-sided mirror skill level +1, prestige in the magic world +500.

"What is the Vanishing Cabinet?" Albert asked again.

"The vanishing cabinet is the same as the double-sided mirror. It has a pair and it can act as a passage between two places. If the object is placed in the vanishing cabinet, it will appear in the other vanishing cabinet." This time he answered yes. Smith.

"The Vanishing Cabinet was very popular in the First Wizarding War. When people were attacked by Death Eaters, they could escape through the Vanishing Cabinet and appear in another place."

"Of course, this kind of thing has two problems. The cost of manufacturing a pair of disappearing cabinets is too high. If the cabinet is broken, it needs professional repairs before it can be reused. In peaceful today, no one will use this expensive magic item. ."

The Vanishing Cabinet feels a bit like a portal to Albert, well, it is a portal.

It's just that the teleportation magic in the magic world is so developed that the technology like the vanishing cabinet is directly forgotten by people. After all, compared to two spoons of Floo powder, the Vanishing Cabinet is too expensive and inconvenient.

However, in Albert's eyes, every technology has its value, and the Vanishing Cabinet is no exception.
