Hogwarts Kryptonian

"I really don't know what you want to do. What is the use of this kind of thing??"

Lu Yunkai brought his newly researched product to Zabini Magical Items Store and handed the sample mirror to his best friend at Hogwarts, Blaise, when he heard his question.

"Why is it useless?" Lu Yunkai spread his hands, "If you write on it, I will receive it immediately... This is a very complicated spell..."

"It's so complicated! It's just the Revealing Spell and the Binding Spell, and at most a Fixing Spell..." Mrs. Zabini interjected from the side.

"Madam, Blaise shouldn't know any of the spells you mentioned, right?" Lu Yunkai glared at her, "And it's not that simple at all!"

Young people talk, but old people hold back and interrupt! !

Do you know that I didn't sleep for five days in a row so that one mirror could send messages to two mirrors alone or at the same time?

"Then you are stupid. This effect..."

"An owl can do it! What's the use of this thing?" Blaise interrupted his mother.

"From the time I write to you receiving the owl, it takes half a day at the fastest, right?" Lu Yunkai shook his head, "But my product is written on my side, and you can receive it immediately, and my mirror can now Send a message to four people at the same time, and you can choose to let one or a few of them see it... Well, although four is not a lot, don't you think it is interesting? "

"It's so complicated!" Blaise interrupted Lu Yunkai's introduction.

"Oh! You don't understand!" Lu Yunkai lamented like a summer insect.

If you live another thirty years, if you have the ability, wouldn’t you use this set of things?

Oh, wizards may not really use it...

"Can it be seen by everyone, or by a specific person among them?"

Upon hearing Lu Yunkai's words, Mrs. Zabini was stunned.

She immediately realized the value of this thing.

If she had one, she would send a message to Blaise when she needed to talk to her son, and contact Lu Yunkai when she needed to talk about business...

Very practical! !

"Yes!" Lu Yunkai nodded with satisfaction seeing that Mrs. Zabini finally understood.

"Isn't that an owl..."

"You can make an owl send messages to me, Draco, and Daphne at the same time, and then let us see them at the same time?" Lu Yunkai explained to Blaise, who still didn't understand.

"Is that necessary? In the worst case, just let the owl deliver it a few more times."

"Well, for example, the four of us have an appointment to come to Diagon Alley to play. You want to choose next Thursday. Draco said that he has something to do on Thursday, so it would be better to go on Friday. Daphne has to spend time with her mother on Friday, and I only have Sunday. If you have time... Come on, do the math. How long will it take you to finish sending the message using an owl?" Lu Yunkai continued to ask.

"..." Blaise was stunned.

Mrs. Zabini on the side laughed.

When he looked at Lu Yunkai again, his eyes were full of appreciation.

Don't tell me, this kind of thing could really happen. Just like when she and a few of her girlfriends and friends wanted to make an appointment to go out for fun or something, they would use owls to send letters to discuss. Sometimes they couldn't make a decision for a month, so they had to find some time to get together to discuss it, and then they could make a decision.

It would be great if there was such a thing!

"How many mirrors are there in a set?" Mrs. Zabini was already very interested in Lu Yunkai's products.

"This thing doesn't matter the group." Lu Yunkai shook his head, "As long as you have one mirror, and then exchange a number with another person who holds this mirror, you can send messages to this person."

"……serial number?"

"Yes." Lu Yunkai nodded, "This number is the number of this mirror in an information transfer system I established. The information you send to another number will appear on the mirror with the corresponding number after being transferred there."

"Can't I make a mirror myself?"

"Your mirror doesn't have a number in my information transfer station, and it doesn't have any related magic!"

"It sounds like this thing of yours has something to do with the method Granger came up with to help you deliver owl letters?" Blaise, who had already understood a little bit, interjected.

"That's where I got the inspiration." Lu Yunkai nodded.

And this thing is called a call center in the Muggle world...ahem.

"Where is your research going?"

Mrs. Zabini, who had completely understood, was so excited that her face turned red.

After being baptized by Lu Yunkai's lucky bag sales, she has gained a little bit of knowledge about doing business, and she has completely understood the business opportunities in Lu Yunkai's set of things.

"Now let's try the five mirrors." Lu Yunkai said this very rigorously, "After all, I built the transfer station myself, and the communication capabilities are very limited. I'm worried that there will be problems because it is not reliable enough. Let's run it for a while. Give it a try and then when I get back to school I plan on adding a few more..."

"Don't!! This matter can't be delayed!" Mrs. Zabini interrupted Lu Yunkai, "You said there were five mirrors. Who else did you give besides this one?"

"Tomorrow is the day Draco and I made an appointment to visit the Potions Master, and I just gave him his one. We can test it first tomorrow night. What?"

"Don't give it to him!! Leave this thing of yours to me!!" Mrs. Zabini didn't care about the astonishment on her son's face beside her, she was so excited that she even let out a girlish voice.

"……you?"

"If the news about you leaks out, people from the Ministry of Magic will probably intervene before you can escape. By then we... ahem, you will have nothing left here." Mrs. Zabini also suddenly realized that her son was still there, and hurriedly He calmed down a little and said, "They even monitor owl communications. They can't just leave this kind of thing alone."

"...Hmm." This Lu Yunkai understood.

"We must build this thing directly so that the people who join it are strong enough to unite to resist the intervention of the Ministry of Magic." Mrs. Zabini continued: "At that time, we only need to collect the communication fee to maintain the mirror every month. You can have enough food and clothing.”

"...You think further than I do."

Lu Yunkai sighed softly.

I just want to be a mobile phone buyer, and Mrs. Zabini just wants to be a telecom operator!

Such ambition! !

"Bruce! You really...have made a good friend!"

Mrs. Zabini thought that if every wizard in England had a mirror, even one person would only have to pay himself five gold galleons a month...

So excited! !

"Don't you think it's a pity that he's not your son?" Blaise looked at his mother's expression of wanting to tie Lu Yunkai to her side, with a black line on her forehead.

He said this very restrainedly, but in fact, what he was thinking about was another...

"Damn kid! What are you talking about!!"

Mrs. Zabini finally woke up from the extreme excitement after being complained about by her own son, and her expression showed a little embarrassment.

"I think I should give Draco a mirror first. After all, what I need now is to check whether this thing is stable or not." Lu Yunkai also felt that the atmosphere was a bit strange, and quickly changed the topic, "Sell it directly without testing it. Go, what if something goes wrong in the future?”

"You can give it to me first... Ahem, well, then you should study it first! By the way, can you give me this mirror first?"

"Oh, sure." Lu Yunkai glanced at Blaise, whose face was already very dark, and regretted it a little.

He shouldn't be allowed to meet in Diagon Alley today.

If I had known that Mrs. Zabini would follow, I might as well have gone to his house myself!

This thing is making a fuss...

"Okay, there's nothing else to do, right?" Blais flinched a little when he saw Lu Yunkai looking at him, and he was too embarrassed to be angry with Lu Yunkai.

To be honest, why should he be angry with Lu Yunkai over this matter? It's his mother there...

well! How can a son blame his mother?

Headache.

"No more. You should accept this mirror first. I will bring another mirror to Mrs. Zabini the day after tomorrow." Lu Yunkai was still a little cautious when he spoke, "I can also try to add an extra mirror to the original one." What an impact it has.”

"You...if this thing is really successful, it might be better than an owl." Blaise saw that Lu Yunkai was still worried about him, so he could only say a few more words.

He has to show that he is not so resistant to this thing, so that Lu Yunkai can know that he is not angry with him, right?

"The owl can also deliver goods, so it is definitely better than this." Lu Yunkai thought for a while and nodded.

However, the idea of ​​integrating the function of item transmission into the mirror secretly began to sprout in his mind at this moment...

"Yeah. Fortunately, the owl is still useful. Otherwise, I don't know what those poor little guys will do in the future." Blaise nodded, "You can't just stew them and eat them, right?"

"..."

Lu Yunkai looked at Blaise, who was laughing after he finished speaking, with an awkward smile fixed on his face.

Dude, you really can't tell a joke.

but……

Is the stewed owl delicious?

…
