Albert was ignorant of Dumbledore's encounter with the Lemays, and he was now frantically absorbing the alchemy knowledge mentioned at the party.

This time, it's really the right place.

Although everyone did not completely disclose their achievements, Albert still learned a lot of useful things, which can be described as a huge gain, which is directly reflected in the fact that the experience of alchemy skills has skyrocketed.

Moreover, most wizards are willing to keep an owl connection with him. Albert naturally did not refuse, but he was very strange, when did he become a fragrant bun in everyone's eyes?

Could it be that they are optimistic about their future?

Albert quickly shook off the superfluous thoughts in his mind and listened carefully to Adolf's explanation of the important principles of the two-way mirror.

In fact, the two-way mirror is no secret in the wizarding world. However, the two-way mirror, which was once popular in the wizarding world, has largely disappeared from the market.

"I have a question!" Albert waited until Adolf had finished speaking, and then asked his own doubts, "why is it that there are basically no people selling double-way mirrors now?"

"Mr. Anderson, like I said earlier, the process of making double-sided mirrors has been gone for many years. Adolf said regretfully.

"Actually, many people know the general principle of this magic mirror, however, after the death of its maker, Brell Persted, the technology to make double-sided mirrors disappeared, and no one can make Breel Birdsted's two-way mirrors. ”

"As I said, two-way mirrors were popular in the wizarding world, and there were still a lot of double-sided mirrors in the wizarding world, and no one was going to make something inferior because they couldn't be sold. ”

Later, with the damage of the double-sided mirror, the number of remnants became smaller, making it difficult to find double-sided mirrors on the market, and the manufacturing technology of double-sided mirrors was gradually forgotten by people, of course, the most important thing is that in order to make double-sided mirrors, you must be proficient in both alchemy and metamorphosis.

The essence of the two-way mirror is that it is an advanced application of the Changing Charm, however, there are very few wizards who can use it on the magic mirror.

Even if he is proficient in alchemy and transformation spells, he has succeeded in creating a two-way mirror. However, the magic cast on an item will weaken over time.

The two-way mirror made by Breel Persd has no such problem, and no one knows the secret to this day.

"It's not surprising that many ancient crafts have been gradually lost, or have been obsolete by the times, like the vanishing cabinets that were very popular in the First Wizarding War. ”

"No, sir, I think a lot of people are mistaken. Albert kindly reminded, "Actually, the two-way mirror is still very popular, take my couple friends at Hogwarts, after they graduated from Hogwarts, they definitely need the two-way mirror to keep in touch, this way is much faster than writing letters, don't you think?"

At this moment, everyone present was stunned, and then someone couldn't help laughing, nodded and said, "What you said is not wrong at all, but our old men are rigid in their thinking." ”

Families can use the Two-Way Mirror to connect with the children at Hogwarts, and couples can use the Two-Way Mirror to communicate with each other, just like a video call, but many people don't think about it.

"Mr. Anderson, you seem to be interested in the two-way mirror?" Adolf asked curiously, "Can you tell me why?"

"I think this technology is promising. "If I had a two-way mirror, I could keep in touch with my family on time every week instead of spending time writing letters." If we have a two-way mirror and want to talk about some alchemical topics, we don't need to write letters, although the owl is convenient, it takes time to come and go, and the letter sometimes does not perfectly express a person's thoughts. ”

"In the Muggle world, there is something called the telephone, which allows people in two places to communicate with each other verbally, and the technology of the two-way mirror obviously goes one step further and brings the two sides closer. ”

"Great idea. Adolf applauded, "If you want the knowledge of the two-way mirror, I don't mind sharing my research with you, maybe one day you can invent a better magic mirror, and don't forget to write my name along with it!"

Hearing the last sentence, everyone couldn't help but laugh. They all knew it was just a joke, and the wizards here didn't care much about fame and fortune because they were so famous in the wizarding world.

"Thank you for your generosity. Albert bowed slightly to the old wizard and said, "If there is a day, I will." ”

At this moment, everyone was quite surprised, and they didn't understand why Albert was optimistic about the two-way mirror, although they had heard Albert talk about the reason just now, but they still didn't understand.

Magic is so handy that wizards rarely feel distanced, and if needed, an apparition or Floo powder can reach their destination in an instant.

This is one of the reasons why the two-way mirror is gradually being phased out, and people no longer need it.

However, such a technology still has many uses in Albert's eyes, and 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.

Lost technology.

You've been exposed to the knowledge of two-way mirrors and have become interested in them, but the technology has been conscious for years, and you've rediscovered the technology to recreate a pair of two-way mirrors.

Rewards: 10,000 experience, 1 skill point, two-way mirror skill level +1, magical reputation +500.

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

"The Vanishing Cabinet, like the two-way mirror, has a pair that can act as a passage between two places. If you place an object in a vanishing cabinet, it will appear in another vanishing cabinet. This time it was Smith who answered him.

"The Vanishing Cabinet was very popular during the First Wizarding War, and when people were attacked by Death Eaters, they could use the Vanishing Cabinet to appear in another place and escape the disaster. ”

"Of course, there are two problems with this kind of thing, the cost of making a pair of vanishing cabinets is too high, and the broken cabinets need to be repaired by professionals before they can be reused. ”

The Vanishing Cabinet felt a bit like a portal to Albert, well, a portal.

It's just that the teleportation magic in the wizarding world is too developed, resulting in technology such as the Disappearing Cabinet being directly forgotten by people. After all, compared to two or two scoops of Floo powder, the Vanishing Cabinet is too expensive, and it is also very inconvenient.

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