Hermione was a great idea, and Evan thought it could be improved to make the "gold" even more functional. Pen % fun % Pavilion www.biquge.info

The use of the Golden Galleon as a communication item is to make it easier to hide and not be discovered.

But if you only have the function of "change the numbers above", it is too simple!

After Evan improved it, only those who wore it could enter the Room of Requirement.

Now, in addition to being able to connect with each other through them, as long as there is an original intention, you can also feel the position of that person.

And each of these fake galleons is unique, which means that only they can use it.

If they fall into someone else's hands, the magic on them becomes ineffective, reinforcing secrecy.

After her most recent training session, Hermione divided the gold coins she and Evan had made among the others.

When Ron saw the gold coins in the basket, he suddenly became very excited, thinking that he really wanted to hand out the gold coins.

"Wait, Ron, don't take it, these coins are numbered on them, and they correspond to each person. ”

"Number?" Ron said blankly, "what is that? Isn't this a golden Galleon? Isn't it true?"

"Of course it's not true!" Hermione said angrily, "You don't want to think about why I'm going to pay you!"

"These Galleons are our future contact props. Evan explained, "I left a spell in it that only we could use, numbered in the order in which you signed your names on the list, corresponding to each other, I was the first, Hermione was the second, then Fred, George, Harry, Ron, Colin, ......"

After a few minutes, everyone received their own gold coins, held them in their hands and looked at them repeatedly.

"What's the use of this thing? It looks like a real Golden Galleon. ”

"Do you see the numbers on the edge of the coin?" Hermione held up a coin that glowed yellow under the torchlight, "On the real Galleons it's just a number, representing the goblin who minted this coin, but the numbers on these counterfeit coins change to indicate when the next assembly will be." The coin will heat up when you change the time, and if you put it in your pocket, you will feel it. We each took one, and when Evan set the time for the next meeting, he changed the numbers on his coins, because I cast a change spell that whenever his coins changed, everyone's coins would change as well. ”

After Hermione finished speaking, everyone was silent, and she looked at the faces that looked up at her, a little embarrassed.

"Well, what's the matter with you guys, I thought it was a good idea!" she said uncertainly, "I've discussed it with Aven, and we both think we need such a liaison item. I don't think there's anything suspicious about Umbridge going through our pockets and bringing a Galleon, isn't there? And Evan changed it, but, well, if you don't want to use ......."

"Will you cast a transfiguration spell?" asked Terry Bout.

"Yes. Hermione said.

"But that's, that's N.E.W.T.s!" he said weakly.

"Oh!" Hermione understood what was going on, trying to be modest, "yes, I think so!"

"Why aren't you in Ravenclaw?" he asked, looking at Hermione in amazement, "You have such a brain, I've never seen a student like you who is only in fifth grade be able to use such advanced spells, and very few people in the school can do it." ”

"The Sorting Hat is seriously considering putting me in Ravenclaw. Hermione said lightly, "But in the end, it was decided that Gryffindor, and besides, I think Evan is much smarter than I am, and he has made more improvements to these Garons." ”

She turned to Ai Wen's side and shook her small fist at Ai Wen while others were not looking.

Then, Hermione shoved Evan out of the way, letting the guy secretly laugh at herself behind the scenes.

"That's right, for added security, I cast a spell at the door of the room, and only the members who carry this Galleon can pass through, making it a symbol of D.A.," said Aven, "In addition, you can also look at the back of the gold coin, the number on it can also be changed, you just need to adjust it like this......"

Under everyone's attention, Evan changed the number to three, which is Fred's number.

As he moved, the back of the coin blurred, and the patterns and patterns on it vanished, turning into a mirror-like reflection, and Fred's face appeared on it, and he was looking at Evan inside the coin with wide eyes.

"Oh my God, how did you do that?!"

"I was inspired by the two-way mirror so that everyone could see each other and use this coin to connect. "But this feature is still being experimented, and if it's too far away, it won't work, and it can only be one-on-one." ”

There was silence for a while, and everyone looked at Aivan, speechless in shock.

If Hermione's change spell just now already made them feel very powerful and incredible, then Evan's improvement was beyond their imagination now, and they didn't even know how Evan did it......

It's not as simple as just a change spell, it's definitely beyond the level of knowledge that can be learned in school.

If you know about it, you will know the preciousness of the double-way mirror.

But for Aven, it's really nothing, he doesn't use any spells, but alchemy.

The two-way mirror was originally an alchemy product, and Aven just made a lot of round mirrors the size of gold coins, and then sneaked them into Galleons, casting a hidden spell, and when needed, they would come out.

Although it wasn't very troublesome for Aven, the others were speechless in shock.

Everyone is accustomed to Aivan's strong strength, and every once in a while they do something that they see as a miracle.

Everyone was amazed and began to look down and study the gold coin in their hands, which was a good thing.

In fact, Evan had a lot of features that he wanted to incorporate into these Galleons, just like Muggle phones, but it didn't work out.

The wizarding world is lagging behind in this regard, and Muggle electronic communication devices are already developing at a rapid pace.

In a few years, this kind of remote calling, video, and interaction will be developed, and Muggles can do a lot of things with their mobile phones.

Evan wondered if wizards would be like Muggles with computers and mobile phones, spending most of their time on them, gradually reducing direct communication between people, and abolishing the ancient tradition of owl mailing, or if they would still maintain the status quo and be left behind by Muggles.

When it comes to the fusion of magic and technology, the wizarding world is definitely not fast, but wizards are not unacceptable.

As long as someone is introduced, everyone is still willing to try new things, such as magic radio, some professional machinery and equipment, and so on.

Aven's shop in Diagon Alley, Muggle-made products also have a lot of wizard attention.

However, most of them see more and buy less, and even if they do, they buy secretly, not wanting people to feel weird.

He felt that when the matter between the evil god and Voldemort was settled, he could specialize in this thing and use technology to change the wizarding world.
