Hogwarts Kryptonian

Although Lu Yunkai had a very busy life in the first two days of summer vacation, he soon became free.

Erin Hill quickly agreed to Lu Yunkai's invitation and took over the job of working three days a week in Lu Yunkai's herbal garden and three days a week at Zabini's magic item shop in Diagon Alley, with one day off.

The monthly salary of 3,800 gold galleons plus the perfect attendance bonus of 200 gold galleons is several times higher than her current income of less than 500 gold galleons a month, and she seems to have no reason. reject.

Because Mrs. Zabini offered a high price, she gave the girl who was eager to find a reliable job a hard time and forced her to sign a lot of magic confidentiality agreements.

However, considering that she has been working at Horror Journey for two years, even if she wants to resign, it will take a while. In addition, Lu Yunkai has been living at home recently, and I always feel that if Irene comes in and out of the house, It seemed a little weird, so he agreed to the arrangement of waiting for her to officially join the job in September.

As for Daphne, Lu Yunkai only went there for two days in a row and found that the two of them didn't seem to have much to do except sit together in a daze. Before, Daphne thought that it would be enough for the two of them to study the archeology her father had prepared for them during the summer vacation. The identification spell was given up by Lu Yunkai because he couldn't figure out why the wood carving was so rare.

So Daphne also said that Lu Yunkai didn't really need to go to play with her every day, he just needed to go there and have dinner together every day.

Naturally, Lu Yunkai would not refuse: Although Xue Li was very quick at work and kept the house in order, her cooking skills were... hard to describe.

In comparison, the Greengrass house elf's craftsmanship is excellent.

It was just two handfuls of Floo powder. He could afford to "transfer" from his home to the Leaky Cauldron and go to Greengrass's home.

And after dinner every day, Lu Yunkai can also tell Daphne, her younger sister who will finally go to Hogwarts this year, about various things about the school, such as the mountain monster, the forbidden forest, the chamber of secrets, the basilisk... which makes people originally full of enthusiasm for the school. Astoria, who was looking forward to it, now feels that Hogwarts is actually another spelling of Dragon's Pool and Tiger's Den.

Ahem.

In this way, Lu Yunkai's summer vacation switched to a rhythm that made him so leisurely that he felt a little flustered.

Just when he felt that relying on the gold Galleons in his hand, this life had been enough to make him die, and he didn't want to fight anymore, he finished visiting his friends in Knockturn Alley and ran all the way (Chrissy said it "only" ran away) After two hours), after returning to the new house, Chris immediately picked an empty room and moved in, ringing his alarm bell.

"It's because the wizarding world is filled with people who think like you that Voldemort can cause trouble!"

After hearing that troublesome name, Lu Yunkai's thoughts of eating and waiting to die suddenly disappeared.

It would be a natural death to wait for death. It would be a shame if someone killed him with a death curse.

It's just that the broken cat that disturbed Lu Yunkai's leisurely life couldn't figure out how to get out Voldemort. He just kept urging Lu Yunkai to learn more while he had time and be prepared, otherwise he would be in trouble when needed. If not, I would be dumbfounded.

Chris's words were correct, but Lu Yunkai really didn't know what he could study.

If he really wanted to study the forbidden book list that Mrs. Pince gave him, Chris might kill Voldemort first before he could take action.

After experiencing the "rapid progress" in the second grade, Lu Yunkai has understood that it is easier to make progress by studying and supplementing knowledge for a certain purpose than by learning what the teacher teaches without purpose.

Well, to put it more professionally, this thing is called a project.

Last year's topic was notebooks and basilisks, but now, Lu Yunkai felt that although it was good to take the identification of wood carvings or the cultivation of herbal medicine as topics, they were not what he was particularly interested in.

And at this time, another person who was not very used to having "leisure time" and lived an extremely fulfilling life gave him a reminder...

After Hermione proved that she could forward a letter to Lu Yun, she would basically write him a letter in two or three days. In addition to various exchanges about learning magic, the content of the letter would occasionally mention some gossip, and a certain She accidentally mentioned in her letter that day that she had installed a landline phone at home, and then suggested that Lu Yunkai could install one if he had a house in the future.

"Muggle things are still very useful."

Hermione felt that Lu Yunkai, like herself, was born as a Muggle, so he shouldn't be from a wizarding family like Ron, who would sneer at these things...

Well, actually Ron doesn't either. The privately modified car that almost caused his father to be expelled from the Ministry of Magic last year showed that the Weasley family still has a positive attitude towards Muggle things.

But Hermione didn't know that although Lu Yunkai already had a house and had no objection at all to installing a phone at home, he had no way of doing it.

If you want to connect to a landline phone in this house, you need to use a magic spell to control the Muggles to lay a long, long dedicated phone line, and then you have to use the Oblivion Charm...

It is estimated that after he has finished this set of things, people from the Ministry of Magic have been waiting for him at home, and he does not need to go back to Hogwarts.

The landline phone was not available, but something that had been sealed in Lu Yunkai's memory came to mind: a mobile phone.

To be honest, most of the Muggle world things in his previous life were forgotten when he first came to this body. The only one Lu Yunkai still remembers and never forgets is probably that he always writes a letter with an owl every time. The mobile phone comes to mind...

This is why Lu Yunkai always dislikes writing letters using owls.

Moreover, Lu Yunkai felt that this thing was much easier to achieve in the magical world than in the Muggle world.

But Lu Yunkai had searched the system before and found that there was no such thing at all, otherwise he would not have had to communicate with Mrs. Zabini through the item transfer cabinet.

But just because there is nothing for sale in the system, it doesn’t mean that Lu Yunkai can’t do it!

And considering his previous experience with powerful curse-removing potions, Lu Yunkai successfully made something and let the system identify it. The system can immediately sell and supply unlimited quantities. This makes Lu Yunkai very ambitious to make a mobile phone belonging to the magic world. .

As long as one is successfully made, Zabini Magic Items Store can sell mobile phones directly!

The thought of this filled him with passion.

However, before he could even check the information, Chris poured cold water on him.

It told Lu Yunkai that it had heard of a kind of mirror that could communicate with each other before. It could not only talk but also see each other's faces. It was so superior to Lu Yunkai's idea that it could only transmit text...

This suddenly opened up Lu Yunkai's mind: Isn't this a video call? ?

Why write a letter when you have such a thing! ?

Then he immediately searched the system and found the thing officially called "Twin Mirrors" among a lot of unrelated items.

It’s not very expensive either, a set costs one thousand gold galleons…

Well, for Lu Yunkai now, it's really not expensive.

After buying a set and researching for a while, he discovered that it is not difficult to make such a "twin" thing using magic. There are even "triplets" and "quadruplets" mirrors for sale in the system...

But these mirrors must be set up with objects that can communicate with them when they are "factory". If you want to add more mirrors to them later, sorry, it's impossible.

This is of course different from what Lu Yunkai wants. What he needs is a mirror that allows him to add and delete his address book at any time, a mirror that allows him to video chat with all his friends, and also allows him to talk to a friend alone...

After finding a topic of interest, Lu Yunkai immediately devoted himself passionately to the study of magic spells and the production of magic items.

And after experiencing the baptism of fruitfulness last year when the book he had been researching for several months was worse than going to the Leaky Cauldron to chat for two days, Lu Yunkai also gave up the idea of ​​working behind closed doors.

First go to Diagon Alley and Knockturn Alley to inquire.

And the facts once again proved that Lu Yunkai's decision was extremely correct: on the first day of his stay at the Leaky Cauldron, a drunk old wizard bragged to Lu Yunkai that he knew a parchment that could be cursed by him. The words he wants will appear at any time.

Of course, the old wizard was a little too proud of the spells he knew and refused to tell Lu Yunkai, but this was not a problem for Lu Yunkai.

Parchment that can transmit text, right? After searching for a whole morning in the system, Lu Yunkai finally found it.

Of course, he didn't want to buy this kind of parchment from the system. He wanted to check out the introduction of the item in the system that he always complained was "detailed and lengthy."

As expected by Lu Yunkai, just like the necklace that Mrs. Zabini sold to Malfoy's mother was stated in the introduction to be "cast with a powerful beauty-preserving spell", the introduction to this parchment clearly explained the above Three spells were cast.

After that, Lu Yunkai used these three spells as keywords to search the system and found the magic items involving these three spells. He looked at their approximate functions and confirmed two of the spells. One was to make text The Appearance Spell is a spell that maintains clarity and durability, and the Enchantment Spell is a fixation spell that enhances the magic circle that ensures that fragile items will not fail due to wear and tear on the items. The remaining one is naturally a useful spell.

Then I looked up the relevant information about this spell from the book...

Magic research is actually quite fun.

However, Lu Yunkai did not realize that in the magic world where magic research is mostly a secret, being able to figure out how much magic is used in the magic items sold is far more difficult than making the items and using magic itself. .

No maker of magic items would let anyone other than themselves know what magic was used on the item, or what magic circles were involved...

Only Lu Yunkai could use the "detailed and lengthy" system description to learn information that was far more valuable than the magic items themselves, and conduct similar research.

Just like that, more than half a month passed in the blink of an eye, and Lu Yunkai finally made the first batch of "prototypes."

The five mirrors were cut into a suitable size according to Lu Yunkai's memory, and the edges were polished so as not to cut hands, making it easier to hold.

Although it is a mirror, it does not support video or calls, and can only communicate by handwriting. It is not inferior to the "quintuplets" mirrors that can be sold directly in the system, but the magic used in these mirrors is the same as what is sold in the system. completely different.

This made Lu Yunkai very excited.

Because he remembered a spell he often used: soar into the sky.

Lu Yunkai did not find this spell in the thickest magic encyclopedia, so he believed that this spell might have been "discovered" by Voldemort himself.

Similarly, in the dungeon, the spell that Lu Yunkai saw Snape using was the magic of Shen Feng Wu Ying. Afterwards, he felt that the spell seemed very powerful and wanted to find the source, but couldn't find it...

Although Lu Yunkai is still a little short of Voldemort who developed his own spells, at any rate, he can already use completely different logic to achieve the same effect.

And with this logic, there are more possibilities!

What he has to do now is to test whether this set of things is stable and reliable.

As for the testing method, he had already thought of it.
