"You've been doing this for so long, is this?" Ron looked at Van Lin with a strange expression, clutching a round gold coin that resembled a gold galleon in one hand.

"Oh, of course. Fan Lin said without raising his head, he still had the last one in his hand, and it seemed that it only needed some simple processing.

"What is this?" asked Harry curiously.

"As you might imagine, at least in terms of feel, appearance and quality, it's no different from the Golden Galleon, isn't it? Van Lin replied calmly, when the brilliance of magic was completely hidden, and the last gold galleon in Van Lin's hand became unremarkable.

"So, you're going to take this when we have to ......"

"Liaison tools," Hermione said to Harry, knowing all about Vanlin Hermione, "don't listen to him, of course it can't be Galleon." ”

"But it all feels the same, Fanlin...... Isn't the Philosopher's Stone dead?"

"It's just a small means," Van Lin said as he cleaned up, "as long as you have sufficient knowledge and good materials, you also have the ability to make a piece, this is just a small function of the Philosopher's Stone." ”

Fan Lin frowned slightly, as if he remembered something, and then his brow relaxed.

"Little tricks?" Ron said in a loud voice, "this is Golden Galleon!"

"Anyway, it's a communication tool. Hermione corrected, "Van Lin, don't tease Ron anymore, or ......"

"Well, this is indeed a golden Galleon," Van Lin said, ignoring Hermione's strange gaze, Van Lin continued, "However, in terms of purity, it is a little different from the normal gold Galleon, I have mixed a lot of brass into it, if you don't believe me, you can take a gold Galleon and give it a try." ”

Ron flicked his head, with the attitude that I believe your nonsense, and you can go on.

"Of course, the real gold galleons are not all gold, and those goblins are also very stingy when it comes to minting coins, so the purchasing power of gold coins is different," Van Lin continued, squeezing a gold galleon with his hand and forcing out a little magic power.

Under everyone's gaze, the gold galleon in Van Lin's hand gradually changed, and after a while, this gold galleon turned into a silver sico, and then quickly transformed into a bronze nat......

"What's going on?" Harry looked up at the Van Lin display, then at the gold Galleon in his palm.

"A little illusion, that's what Collin inspired me. "Otherwise, a Hogwarts student would take a gold galleon from his pocket, which would be a bit of a striking, so I changed the design so that everyone could choose according to their personal preferences." ”

"So, it's really just a communication tool?" said Harry, but there was nothing strange about the feeling that the golden galleon gave him.

"That's right, if you activate it with mana, you can talk to each other, store information in it, and export information in the same way. "Because it's so simple, the fluctuation of magic power will be very small, and even if you use it in front of others, it won't be noticed, just like now." ”

"Now?"

Hermione looked down, "How do you use this?"

"Magic!" Van Lin said, "through the contract, I clearly remember the information of everyone's magic power, and your magic power has its own attributes, all of which are recorded, and only need to be output." At the same time, it is also possible to make a multi-person call when multi-person is active, but I don't recommend doing this, it will be very confusing, of course, if you want to speak to only one person, you need to add a name in front of it, you know, names are very important for wizards, and there are some principles of curses. ”

"Like that?" Hermione said, a little magic activated, and a message came out of the gold coin clearly, but there was no sound around, as if it was coming from the ear.

Harry and Ron tried as well, and in an instant, what Van Lin had said before reappeared in their minds.

"It's fantastic," Harry said, "that we don't have to be found out about our connections, and we wouldn't have been able to get together in the first place......

"You mean Umbridge's new rules?" asked Vanlin.

"Yes, you know?"

"I saw it when I came out in the morning, but it's not a strange thing, isn't that what Umbridge did? she's here for one purpose, to bring down Hogwarts, and banning everyone from communicating is a good option, and there will be more rules in the future. ”

"What's in it for her?" Hermione said, puzzled, "stump she didn't walk out of Hogwarts?"

"I'm afraid not," Ron shrugged his shoulders, "I don't think the house would take her, and Slytherin's words...... My dad told me that Umbridge guy wasn't a pure-blood wizard either. ”

"Don't mention pureblood, not pureblood. "I'd like to believe that Umbridge is from Slytherin, after all, if the pureblood family had been kept pure-blooded, the pure-blood family would have been doomed a long time ago, and you don't know what the consequences of marriage would be?"

"What consequences?" Ron looked at Van Lin in disbelief.

"It's an idiot...... "Fan Lin rolled his eyes, "Either it's a squib, or some mental illness or physical illness, anyway, it's nothing good, like the Gaunt family, it's just a miracle, especially since the bloodline of the first pure-blood wizard is combined with powerful magical beasts, this will be a problem sooner or later." ”

"You mean the Gaunts?" Ron said, "I've heard my dad mention that they ......."

"They're already exterminated, right, that's the end. Van Lin said that he didn't seem to be going to continue the issue, otherwise it would not be a reliable thing to talk to Ron about Voldemort's past and present.

"By the way, Harry, you and Ron find a way to get this thing out of everyone's hands, everyone has it, and then tell them how to use it, as for the place to practice......"

"How about this? Room of Requirement, it's big enough here, I think it's ......"

"Let's talk about it then, the next meeting is still scheduled for Hogsmeade, and I'll find a way before that, in fact...... The castle is not too safe. Van Lin thought about it, he didn't want Umbridge to destroy his lab because of this.

"What are we going to do next?" Van Lynn asked.

"Professor Binns's History of Magic. Hermione replied, "I wish Professor Umbridge would come over and get a good look at history." ”
