Vol 2 Chapter 993: Double-sided mirror on gold coins

Hermione had a great idea, and Avon felt that it could be further improved to make the functions of these "gold coins" more perfect.
The use of Jin Jialong as a contact prop is for the sake of hiding and will not be discovered.
But only the function of "changing the numbers above" is too simple!
After the improvement of Ai Wen, only those who wear it can enter the responsive room.
Now, in addition to being able to connect with each other, everyone can feel the position of that person as long as they have one original intention.
And each of these fake gallons is unique, which means that they can only be used by themselves.
If they fall into the hands of others, the above magic will be invalidated, and privacy will be strengthened.
After the last training, Hermione distributed the gold coins she and Ivan made to everyone.
When Ron saw the gold coins in the basket, he suddenly became very excited, so he really wanted to send gold coins.
"Wait a minute, Ron, don't take it casually. These gold coins have numbers on them, which correspond to everyone."
"Number?" Ron said slyly. "What is that? Isn't this Jinjialong? Isn't it true?"
"Of course not true!" Hermione said with a sigh of relief. "You don't want to think about it, what do I do for you!"
"These Galleons are our future props." Ai Wen explained, "I left a magic in it, so that it can only be used by ourselves. The order of the numbers is the order in which you sign the names on the list. Corresponding to each other, I am the first, Hermione is the second, and then Fred, George, Harry, Ron, Colin..."
After a few minutes, everyone got their own gold coins and looked at them repeatedly.
"What is the use of this thing? It looks like the real Jin Jialong."
"Do you see the number on the edge of the coin?" Hermione raised a coin for everyone to see. The coin glowed yellow under the torch. "On the real Galleon it is just a number, which represents the coin. The goblin, but the numbers on these counterfeit coins will change, showing the time of the next rally. The coin will heat up when you change the time, if you put it in your pocket, you will feel it. We each take one, Ivan determined At the next gathering time, I modified the number on his coin because I applied a change spell. As long as his coin changes, everyone's coins will change as well."
After Hermione finished speaking, everyone was silent. She looked at the faces that looked up at her and was a little worried.
"Well, what's going on, I thought it was a good idea!" She said with no confidence, "I have discussed with Ai Wen, we all think we need such a contact prop. I think, even if Umbridge wants to turn Our pocket, with a Galleon, is nothing suspicious, isn't it? And Avon has changed it, but, well, if you don't want to use..."
"You will cast a change spell?" Terry Bout asked.
"Yes," said Hermione.
"But that is, that is the level of n.e.w.t.s!" he said weakly.
"Oh!" Hermione understood what was going on, and she tried to be modest. "Yeah, I think so!"
"Why didn't you be in Ravenclaw?" he asked with amazed look at Hermione. "You have such a brain. I have never seen a student like you. Only in the fifth grade can you use such a deep spell. Few people in the school can do it."
"The split hat is just thinking about putting me in Ravenclaw." Hermione said softly, "I can finally decide Gryffindor. Also, I think Avon is much smarter than me. He is right. These Galleons have made more improvements."
She turned to come to Ai Wen's side, glaring at others and not paying attention to Shaman's small fist.
Then, Hermione pushed Ai Wen out and let the guy sneak a joke in the back.
"This is the case. In order to enhance security, I applied a magic at the door of the room. Only members who carry this Galleon can pass it, making it a symbol of da," said Ai Wen. You can also look at the back of the gold coin. The number above can also be changed. You only need to adjust it like this..."
At the attention of everyone, Ai Wen changed the number to No. 3, the number of Fred.
With his movements, the back of the gold coin was blurred, the pattern and pattern on it disappeared, and it became a mirror-like reflection. Fred’s face appeared on it. He was staring at the Avon in the gold coin. .
"God, how did you do it?!"
"I was inspired by the double-sided mirror, so that everyone can see each other and use this gold coin to contact." Ai Wen said, "But this function is still in the test, it will not work if you leave too far, and Only one to one."
A moment of silence, everyone looked at Ai Wen, shocked and could not speak.
If Hermione’s change curse has made them feel very powerful and incredible, then Avon’s improvement is beyond their imagination. They don’t even know how Avon did it...
This is not as simple as a change curse, and the difficulty is definitely beyond the level of knowledge that the school can learn.
If you have a relevant understanding, you will know the preciousness of the double-sided mirror.
But for Ai Wen, it really is nothing, he did not use any magic, but alchemy.
The double-sided mirror was originally an alchemy product. Avon just made a lot of gold-sized circular mirrors, then sneaked them into Garon, cast a hidden spell, and they will come out when needed.
Although it is not very troublesome for Ai Wen, others have been shocked and can't speak.
Everyone has become accustomed to Ai Wen’s strength, and he has made some things that make them think miracles.
After everyone was amazed, they began to look down on the gold coins in their hands. This is a good thing.
In fact, Ai Wen still has a lot of features to integrate into these Galleons, just like Muggle's mobile phone, but in the end there is no success.
The magic world is lagging behind in this respect, and Muggle's electronic communication equipment is already developing rapidly.
In a few years, this kind of remote call, video, and interactive functions will be developed, and Muggles can do a lot of things with their mobile phones.
Ai Wen didn't know when the wizards would be equipped with a computer or mobile phone like Muggles, spending most of their time on it, gradually reducing the direct communication between people, and canceling the ancient owl delivery. The tradition is still maintaining the status quo, and it is getting farther and farther away from the Muggle.
In terms of the fusion of magic and technology, the speed of the magic world is not fast, but the wizards are not unacceptable.
As long as someone introduces, everyone is still willing to try new things, such as magic radio, some professional mechanical equipment and so on.
Ai Wen has a lot of sorcerer attention in the shop in Diagonal Lane.
However, most of them buy more and buy less, and even if they buy it, they buy it secretly, and don't want to make people feel strange.
He felt that after the evil spirits and Voldemort had been resolved, they could specialize in this matter and use technology to change the magic world.
