"You can leave your mage sigil and we will send it to the Supreme Council for safekeeping, and the public key of the Supreme Council has been saved in the badge, and the council can use this public key to send messages to the Supreme Council. ”

The chairman introduced to Kaichi.

Jia Yi looked at the lead box, there was a piece of parchment at the bottom of the box, he took out the parchment, and carefully examined it, this is the standard parchment of the Supreme Council, and there is also the mark of the Supreme Council on it, and there is nothing special. Kaichi activated his new badge and stamped it on the parchment, leaving a sparkling spell on the parchment.

This is the public key from the pair of keys he has just activated printed on the parchment.

He then flashed a layer of magic on his fingers, and scribbled his spell signature on the parchment, a spell signature that was the unique mark of a mage, similar to a fingerprint, and would not be the same for any two mages, and would not change unless there was no accident.

He put his spell public key into the box, and then encrypted the box with the public key of the Supreme Council that had been stored in the badge, so that unless there was a corresponding private key, brute-force opening the box would definitely destroy the original secret key, damage the box, and even if it was encrypted twice, it would leave a mark.

Some of them are more confidential, and if you break the key, the entire inside of the container will be destroyed.

This process Jia Yi is actually familiar with, and it was also this process when he first got the badge, and now he just replaced the original mage key with an asymmetric key.

Kaichi handed the box back, and the box would eventually be transported back to the Supreme Council via the guild's transportation lane, where it would be used as a secret key for separate communications.

The president then handed over a parchment and said, "This is the public key of each of Moshacher's magazines, you can save it yourself, it is much more convenient to use this public key to transmit official documents." ”

The biggest benefit of asymmetric encryption is this kind of public file transmission, the security has a great guarantee, if it is private, in order to keep it secret, you can set a key that only two people know, but the public key can not do this.

Jia Yi copied these public keys on his spell book, and the mage badge did not have too many storage functions, so he could not store too many secret keys, so he could only copy them on magic parchment, and temporarily "rubbed" them when he used them.

After replacing the badge, Jiayi put away the old badge and asked with a little curiosity: "President, may I ask why the trees in the association have grown beyond the wall, why don't you dispose of it, don't you worry about damaging the load-bearing of the wall of the chamber of commerce?"

Although Jia Yi didn't continue, he was able to think of it.

The guild leader was stunned for a moment, because no one had asked him this question for too long, he didn't react for a while, he smiled and said to Jiayi: "Don't worry about this, these trees are not simple trees, but part of the association's defense." ”

Jia Yi was stunned by what he said, although these trees look a little distorted, but they don't look like they have any power, no matter how ordinary they look.

The president introduced: "These trees were cultivated by the first president of our association, and they have been combined with the association's defensive array, if there is any change, all the trees will become immobile 'war ancient trees', and they will be able to compete with the purple-robed mage in a short time." When not activated, these trees look the same as normal trees. ”

It was a complete accident that these trees would become like this, and the first president found a few seeds of magic trees in the Ridge Bay Forest and cultivated them in the guild, but he later went out and forgot about the saplings he cultivated. By the time he returned, the saplings had grown so well that they had broken the walls, and eventually merged with the walls of the association, forming a special symbiotic relationship and providing a special layer of protection for the association.

In fact, it has always been a mystery why it ended up being the way it is, and no one has been able to replicate this miraculous phenomenon after these magic trees.

Over time, the combination of the trees and the walls has become a feature of the association, even though it makes it look like it is about to collapse.

After learning about the special nature of the association, Jia Yi relieved his heart a little, and then asked the other party: "I heard that there are a lot of medicinal herbs produced in the forest here, are there any special medicinal herbs here?"

The president thought for a moment: "There are many types of medicinal herbs here, and the yield is also high, but most of them are not very high-level, and there are very few rare medicinal herbs produced. ”

It is also because the level of medicinal herbs is not high, so most of the mage levels here are relatively ordinary, and Jia Yi is already the highest-level mage in the past two years.

"Occasionally, you can find redstone roots here, which can be used to make a very effective boiling potion, which can be used to encourage magic and expand the magic pool in the spiritual sea. ”

This is a good thing, no one will dislike their mana pool is too big and has too much mana, but this potion should not be used too much, otherwise it is easy to make the mana sea unstable and reduce the control of mana.

"Redstone roots, where can I buy them here? Are there any in the guild? I've only heard of this material and haven't used it. ”

The leader shook his head: "This kind of potion main material that can increase the capacity of mana is rarely taken out and circulated, and the output of redstone roots is relatively rare, if you want to buy it, you can go to the east market to see, most of the herbs collected from the Ridge Bay Forest will be bought and sold here, and many people will only sell the rest of the things in our association after buying and selling there." ”

The Mage Association also works part-time in the buying and selling of items, but the price will be lower, and the price of the things sold will be higher, but the quality of the things here will be better, even if there are any flaws, it will be explained, and there is no need to worry about being cheated.

In other words, the pit is also above board.

Kayi said goodbye to the president, then went to find a hotel to stay, sorted out his things, then took out his paper on copper crystal communication, read it again, copied a copy of the bottom, and then packed the paper in a wooden barrel, stamped it with the key of the journal "Electromagnetism", and prepared to send the paper to "Electromagnetism".

This is the first time he has submitted to the four major journal-level magazines, in his opinion, Tongjing Communication should barely be enough, in fact, the original Elf Rice also had this opportunity, just for the sake of secrecy, the Elf Rice did not publish any papers at all.

Soilless cultivation published a paper, but it was not published in Life.

However, it is also very risky to want to be published in Electromagnetism, and if you don't get selected, the time will be wasted, and it will take a long time to review the manuscript. Especially when he is traveling, if the review fails, he doesn't know when he will receive the message.

Fortunately, he now has Tongjing Communication, and his mailing address is written with his teacher, and if the audit fails, he will mail a letter to his teacher, and Orlando will send a newspaper to Jiayi to notify him.

After loading the paper, seeing that it was still early, he was going to go to the market mentioned by the president of the association, and even if he couldn't find the redstone root, he could find some fresh herbs to use to prepare the potion.
