Chapter 487: Test, global broadcast

Immediately afterwards, Xia Duo made another laboratory version of the communication artifact. After all, how to use it if there is only one communication artifact? If it is directly transmitted to a natural person, the recipient must manually unlock the encrypted information, which is very inconvenient.
In addition, in order to sell products more conveniently, Xia Duo directly restricted that only communication instruments connected through the "Twin Secret Art Mark" can communicate with each other. If two people can't see even one side, then remote communication is actually not necessary.
Of course, on the other hand, the two-loop [Background Communication] simplified by Xia Duo can also be used, but this can only be used for direct communication between people, analogous to dialogue, but what is passed is text information.
The next step is the actual test. Xia Duo put away the two laboratory versions of the communication instruments and came to the Tillak research room, first checked their research progress, and then called Dean out.
"Come and help me test a communication instrument."
"Well, good!" Dean promised readily.
In fact, he has been so busy these days that he does not know the night and the day. In addition to the experiment on eternal magic, he is more of a supplement to his own knowledge. Xia Duo provided the members of the society with theoretical knowledge such as arcane geometry. In this regard, the progress of Sami and others is slightly faster.
This made Dean feel pressured, so he used almost all of his free time, but he was a bit exhausted by squeezing himself for a long time. This time Xia Duo had something to do with him, and he just came out to relax and adjust.
Soon the two went through the portal and came to Savile Town. The first thing to test was the communication connection in the normal magic net environment outside.
Xia Duo took out the two lab version communication artifacts that had not been "encapsulated" just now, and handed one of them to Dean's hand, and then cast the [Twin Secret Art Mark] on these two communication artifacts. At the same time leaving two identical marks.
If this step is performed by two people together, it may have a certain ritual meaning, indicating that this is the beginning of a connection between two people. Of course, it is also possible to perform it alone.
Now Dean hadn't learned this spell, so it was Chardonnay to cast it.
"I will teach you how to use this communication tool first."
The use of communication instruments is very simple. You only need to activate the communication instruments in the state of concentration, and then input text, which exists in the form of light and shadow.
It is said that it is text, but it is still projection in essence, but the information carried by text projection is the least, and the 2nd-level spell can only do this step.
If Dean is an earthling, maybe you can insert some emojis in the text to express more complex information. But as of now, Xia Duo has no plans to introduce emoji in the wizarding world.
After a while, Dean fully understood the use of this strangely shaped communication artifact, but when he was about to stimulate it, Chateau stopped him again.
"Wait a minute."
I don’t know if it was the impact of the papermaking incident some time ago. Xia Duo is now very sensitive to this kind of external affairs. Although the communication instrument is already an "old thing" that already exists, he is still not sure whether anyone is doing it. Predict technological breakthroughs in this area.
But if you are cautious about everything, then don't do anything.
Therefore, after thinking about it, Xia Duo decided to put the test outside to do it, but he still had to do some simple protections, and the blessing of Dean to avoid detection was one of them.
At the same time, Xia Duo decided that after communicating the magic weapon, after the advanced arcanist, in addition to the normal "upgrade", the first thing he should do is to study the detection spell and counter-detection spell.
This is a bit like electronic countermeasures in modern warfare on Earth, reconnaissance and counter reconnaissance, jamming and counter jamming.
Mastering the initiative can be regarded as the key element of success or failure.
Doing the basic protection work, Chateau told Dean to test after receiving his notice, and then teleported to the north. He teleported to the farthest place as far as possible, and the sight was a strange forest.
Fuzzy teleportation does not require specific coordinates, but the risk is greater, but it is generally still under control. Generally speaking, wizards are reluctant to accept spells with too high uncertainty.
According to the position of the sun, Xia Duo roughly judged which side was south, and then flew to a high place to look at the south. The earth was flat, and he could see the end of the world at a glance.
But the fact is that human vision is limited, and it will be blurred beyond a certain distance. In addition, there are various mountain ranges that are much higher than the height of the eye. In fact, the scope of seeing (seeing clearly) is very limited.
Of course Xia Duo wouldn't fly too high, and the limit of his vision was probably the Wolf God Mountain south of the Green Pearl Forest.
According to the size and clarity of the Wolf Mountain, the distance can be determined theoretically, but Xia Duo doesn't need to be so troublesome. He only needs to know that the teleportation is far away this time, far beyond the range of ordinary messaging spells.
He tried a few conventional single-player communication spells~EbookFREE.me~ but Dean didn’t respond, so he probably didn’t receive it. If there is no Mage Tower-level communication array, Chateau feels like he and Niya It should not be so easy to contact every now and then.
Of course, it is not that there are no communication artifacts that can be contacted at a distance, but those communication artifacts are not based on [Communication], many of which are related to projection and summoning, and some are even related to curses.
For ordinary wizards, the threshold is extremely high, so it is better to borrow the communication circle of the wizard tower.
Chateau remembered that Mrs. Patty should have a long-distance communication artifact in her hand, and even the Langas people can contact Savile Town, but the use of that communication artifact is very restricted.
At least it's not like the communicator made by Chateau that can be used at any time.

2 Ring [Background Communication]·{Start Test}
Similar to the fuzzy transmission of [Transportation], [Background Communication] can also be sent in a fuzzy manner, but even if it is a fuzzy transmission, it is similar to the precise delivery of big data on the earth.
[Background Communication] It uses Monet's background fluctuations to transmit information, which is essentially a large-scale global broadcast.
The target that Xia Duo chooses is [South, scene, image of Dean]. Within the scope of the spell, although the spell will not automatically retrieve the target, only the target can be received.
Of course, on the other hand, this kind of global broadcast communication is also easy to be intercepted, especially when the number of users is small and not encrypted.
If there are many users, it is not easy to find specific information.
Based on this, Xia Duo also inferred that in the future, there may be monitors specifically targeting Monet's background fluctuations.
In general, encrypted communication is still a major trend, and communication instruments can't be sold.
