After Rolf's spell plug-in, Song Ye's efforts, he finally got the spell model of the Communication Stone.

After some research, Song Ye found that this spell model was optimized to be able to exchange sound and image information in addition to text information.

Of course, Rolf chose to optimize, although those functions are not needed at this stage, but these things always have to be updated, right?

He also suddenly realized that this ...... Isn't it the basic version of VX? Rolf is determined to speed up his research, and when the time comes, won't it be a weapon to make money?

After he got the optimized spell model, he carved the spell model into the magic mirror with mental power.

After hearing about Rolf's idea, Song Ye directly optimized this communication circle into a magic circle similar to the sub-mother array, through which information can be exchanged between each sub-array.

And what Rolf has just carved into the magic mirror is the mother circle of the communication circle.

After the depiction was successful, he casually picked up a newly bought notebook, carved a communication circle, and prepared to experiment.

The message written by Rolf in the new book magically appeared in the Horcrux diary that had been integrated into the soul before.

Could it be that because this Horcrux diary has added the soul energy of the magic mirror, it can receive all the information of the communication circle?

In other words, this diary is a doppelganger of the magic mirror?

Rolf was thrilled by this discovery, which was the most powerful way to spy on the entire wizarding world, but only if it could be sold in large quantities.

Otherwise, if there are not a few wizards to use it, everything is just empty talk, who can Rolf spy on?

Next, Rolf told the elves to suspend the refining of the thermostat and leave it all to Awan alone.

And the rest of the elves were all put into the refining of the new communication notebook.

In Rolf's vision, each page of the notebook depicts a communication circle, and then leaves each other's magic imprints to form a one-to-one exchange of information.

And this magic imprint is the epitome of the wizard's own magic power, which is irreplaceable.

This magic sigil is unique to each wizard, and it is impossible for two people with the same magic power to appear, just as there are no two people with the same fingerprints.

Rolf excitedly picked up the notebook of the test product No. 2 just now, and personally carved out the communication circles, preparing to conduct further experiments.

The next thing to experiment with is how long this information can be kept, and the magic mirror's answer is that if his soul energy can be further enhanced, this information can be stored forever.

But the notebook obviously can't hold so much information, but fortunately this is a wizarding world, and with a wand, Rolf easily solves this problem.

Each communication parchment can display 20 lines of information, and if you want to find previous chats, you need to use your wand to pronounce the keyword you want to find.

You may not believe it, but this function is actually achieved by flying to the spell.

By carving the Flying Charm on parchment and connecting it to the spell model of the communication circle, Rolf enabled wizards to quickly find the information they were looking for as they searched for it.

With the success of one experiment after another, the communication notebook has become more and more perfect, and finally the idea of group chat, but at present, this function is still difficult to use at will.

Rolf's solution is to create an independent information channel similar to a chat room through the Magic Mirror, and only a notebook that recites the correct spell can enter the chat room

However, this chat room needs to open up another line, and the exchange of information in it will consume a lot of the computing power of the magic mirror.

Rolf was going to call it the Owl Notebook, and considering that most wizarding families were not wealthy, the price of each page of parchment engraved with the communication circle was 5 silver sicos.

1 gold galleon = 17 silver sike, and 5 silver sik is about equal to 20RMB, which is still acceptable to the average wizard family.

Each owl notebook has a signature formation on the cover, and wizards represent their magic imprint by filling in the relevant symbol or name.

For now, it's a bit unrealistic to ask Rolf to buy or rent a shop in Diagon Alley, as he doesn't have that much gold galleons.

But he can't sell it by himself, first, Rolf doesn't want to reveal his identity, and second, he is about to start school, but he doesn't have time to manage this.

In the end, he decided that it was better to cooperate with the shops in Diagon Alley to sell **, and each piece of parchment with the formation burned, the store could draw one percent, which should be quite attractive.

After the comparison, Rolf chose the Transform Ink Stationery Store, as for why, because the store was able to provide Rolf with parchment paper for free......

As a result, the day after the cooperation was negotiated, Malfoy's owl sent two notebooks, which were the owl notebooks he had made, and attached the letter with how to use the notebooks and Malfoy's letter:

Yesterday I heard that there is an owl notebook in Diagon Alley, which allows wizards to communicate directly from a distance, so I brought one for you and Harry, and when we meet, we can leave a magic mark on each other, and we don't need owls to send letters anymore!

Just as Rolf lamented that Malfoy was well-informed, the system prompted that the mission system had been updated.

Rolf is surprised to open the quest system and prepare for what triggered the system to issue a new quest.

Main Mission 1: Earn 400 XP to upgrade to Level 3 Plane Merchant (104/400)

[Mission Description: Gain 3 experience points after each successful first-level transaction, and 1 experience point after five-star praise, work hard to complete the task and become a better plane merchant!]

Main quest 2: Create your own shop and open a branch in the Atlas, you can get 0.5 general experience points for each transaction in the store, and 1 point of lottery experience for each transaction in the branch. （0/1）

[Mission Description: As your home base, how can the Overworld not have a shop? After successfully owning a shop, it means that you have enough ability, so keep working hard!]

Rolf regretted that he had taken the newsletter parchment and the owl notebook to the Transform Ink stationery store and sold them.

What a lot of experience is this! It's all gone, so we can only collect funds as soon as possible, supply less, and try to recover some losses.

Hey, I should have thought a long time ago that I could get experience points by opening a branch in the other world, and I would definitely be able to open a store in the main world!
