HP: Hogwarts, but pro-generation

"You mean, you have already developed something that allows people to chat at any time and in any place?"

As Ander finished speaking, the curiosity of the other boys was piqued. They knew about Xia and Lily's research through their descriptions. After being in the magic world for so long, the little wizards sometimes still felt that it was inconvenient to send letters by owl. Although sending letters by owl sounded cool and very consistent with the image of the magic world, when they thought about being able to chat in real time, nothing could be cooler than this!

"Yes. Lily and I thought about it for a long time. No matter how fast an owl can deliver a message, there will still be a time lag. If there is something very urgent but there is no way to say it in person, it is still very useful to have a chat tool." Xia explained. After that, she glanced at Ander and the others and said sarcastically, "Oh, I don't know who swore on the day of the holiday that this matter would be taken care of by them~ It couldn't be you, Ander, James, Remus, and Sirius?"

When she said the last name, Xia slowed down her speech, and her tone was gentle and soft, giving people the feeling that it was like a pleasant note passing through the air. She didn't show it very obviously, and before everyone had time to appreciate the difference, Xia returned to her usual self. Except for those who knew about it, no one else noticed anything, but Sirius was half a participant after all, and he keenly sensed that something seemed to have changed quietly.

When he wanted to think about the details carefully, Ander suddenly interrupted his thoughts. He only heard Ander say loudly: "That's because we are also busy. But if there is still a need for us later, we certainly won't refuse."

After all, this chat tool was very attractive to them. As long as it was made, everyone present would have at least one. They didn't want to take the credit of Xia and Lily for nothing. With the idea of ​​helping as much as possible, Ander made the decision on behalf of James and the others.

On the other side, Christian also smiled and said that he could help, but, "Excuse me, I want to ask if everyone can chat together in real-time?"

Sirius tutted and said, "If you don't want to join, just say so." He then rolled his eyes at Christian.

"See, this is why I don't want to join." Christian spread his hands innocently, his tone was still calm, but his words were completely different. Sirius almost couldn't control his temper when he saw him like this, he wanted to continue to mock him, but fortunately Remus stopped him.

Then Christian said to Xia: "But if you need help, I won't refuse."

"Oh! Thank you in advance, Christian." Xia responded with a smile. She thought carefully about what Christian said and felt that his idea was very feasible. She said, "It's a good idea. Maybe we can start with a one-on-one chat."

"We have tentatively decided to chat in a diary. If it is inconvenient to carry, we can also chat on parchment." Lily added, "We will use the Apparition Spell and the Vanishing Spell - if we don't want the chat content to be seen."

"There's a problem." Remus pointed out sharply, "Is everything going to disappear? That would be a shame."

Regulus nodded in agreement. He had also discovered the problem, but Lupin had just said it before him. However, he thought of a solution: "You can inject magic power. I know that many magic items that recognize their owners are infused with magic power. All you have to do is use your own magic power as a key and connect it to the vanishing spell."

"Oh! What this means is that if you inject your own magic power, you will be able to see it. If it is not your own magic power, all you will see is a blank. This way, you won't have to worry about someone else picking it up and seeing the contents after you lose it."

Regulus gave James an affirmative look, as if to say that he didn't look that stupid. James didn't care about these little details, he smiled and accepted the affirmation from Regulus. Seeing James's complacency, Regulus couldn't help but turn his face away and sighed that the boys in Gryffindor were really a bunch of shameless guys.

"Since magic power can be injected, as long as each party's magic power exists in the other's notebook, they can start chatting." Severus mentioned.

But this seems a bit difficult. How can you make sure that the person on the other side is the one you are looking for? Several little wizards huddled on the sofa, one hand holding up their chin, the other hand supporting the elbow of this hand, and began to think. Penny was not interested in their chat. She was completely indifferent to the magical world. After many problems, maybe two years ago she would want to join their chat, and if she couldn't join, she might be angry, but now she knows that there are some things that she can't join just because she wants to.

But she still said, "Then why not mark it when leaving the other person's magic?"

Seeing that everyone else's eyes were all on her, Penny felt a little uncomfortable. She brushed the hair that hung by her ears and said, "Well... I mean, we - that is, Muggles, can already chat online[1]. We add each other as friends and click on the avatar. Why can't we treat magic as an avatar?"

Her words gave great inspiration to the little wizards present. They gave Penny an appreciative look and said that her idea could be of great help. Xia and Lily seemed even more excited.

"In this way, as long as each 'avatar' is marked, people with magic in the same 'avatar' can chat together. If an 'avatar' only has the magic of one person, then it's a single-person chat." Lily combined her little knowledge of the Internet and quickly began to think divergently.

"Oh, Penny!"

After hearing Lily's thoughts, Xia hugged Penny fiercely. Lily on the other side put her head on Penny's shoulder. The two of them held Penny tightly on the left and right. They raised their heads together and looked at the blond girl who was a little shy and timid at this time, and said, "I can't imagine what we would do without you!"

"Hey! We obviously contributed, why doesn't Xia thank me?" Ender muttered softly, but was completely refuted by Remus' words "girls' friendship". He swallowed the rest of what he wanted to say and said reluctantly: "Oh, okay, you are right."

But when Ander looked at Xia opposite him, he inexplicably felt a surge of pride in his heart. See, my sister is so amazing.

If Xia knew what Ander was thinking, she would probably say that she had always been so capable, but Ander just didn't know it because he lacked the eyes to notice it.
