Lord of Arcane

Chapter 487 Testing Global Broadcasting
Immediately afterwards, Xia Duo made another laboratory version of the communication magic weapon. After all, how to use it if there is only one communication magic weapon?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 artifacts connected through the [Secret Imprint of Twin Birth] can communicate with each other. If two people can't even see each other, then remote communication is actually not necessary.

Of course, on the other hand, the 2nd Ring [Background Communication] that has been simplified by Xia Duo can also be used, but it can only be used for direct communication between people, analogous to dialogue, but the transmission is text information.

The next step is the actual test. Xia Duo put away the two laboratory versions of the communication magic weapon and came to the Tilak research room. First, he checked their research progress, and then called Dean out.

"Come here and help me do a test of the communication instrument."

"Well, good!" Dean agreed very readily.

In fact, he has been so busy these days that he doesn't know night and day. In addition to the experiment on permanent magic, it is more about supplementing his own knowledge. Xia Duo provided theoretical knowledge such as arcane geometry to the members of the Advanced Society. In this regard, the progress of Sami and others is slightly faster.

This made Dean feel the pressure, so he used up almost all his free time, but it also made him a little physically and mentally exhausted to squeeze himself for a long time. This time, Xia Duo had something to do with him, so he just came out to relax and adjust.

Soon the two passed through the portal and came to Savile Town. The first thing to test was the communication connection under the normal magic net environment outside.

Xia Duo took out the two laboratory-version communication instruments that had not been "encapsulated" just now, handed one of them to Dean, and cast the [Secret Imprint of Twin Births] casually. Two identical imprints are left at the same time.

If this step is cast by two people together, it may have a certain ritual meaning, indicating that this is the beginning of the connection between the two people. Of course, it is also possible for a single person to cast the spell.

Now Dean hasn't learned this spell yet, so Xia Duolai casts it.

"I'll teach you how to use this communication magic weapon first."

The use of the communication magic weapon is very simple. You only need to activate the communication magic weapon in the state of concentration, and then enter the text, which exists in the form of light and shadow.

It is said to be text, but it is still a projection in essence, but the text projection carries the least information, and the second-level spell can only do this.

If Dean were an Earthling, maybe some emoji could be inserted into the text to convey a more complex message.But so far, Xia Duo has no plans to introduce emoticons in the magic world.

After a while, Dean fully understood how to use this strangely shaped communication instrument, but just as he was about to activate it, Xia Duo stopped him again.

"Wait a minute."

I don't know if it was the impact of the paper-making incident some time ago. Xia Duo is now very sensitive to this kind of work in the outside world. Although the communication magic weapon is already an "old thing" that already exists, he still cannot be sure whether someone is doing it. Technological breakthroughs in this area are predicted.

But if everything is cautious, then nothing should be done.

Therefore, after much deliberation, Xia Duo decided to put the test to the outside world, but he still had to do some simple protection, and blessing Dean with [Detection Avoidance] was one of them.

At the same time, Xia Duo decided that after the communication magic weapon and the advanced arcanist, in addition to the normal "upgrade", the first thing he should do is to study detection spells and anti-detection spells.

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.

After doing the basic protection work, Xia Duo told Dean to conduct the test after receiving his notification, and then teleported to the north. He teleported as far as possible, and the place he saw was an unfamiliar forest.

Fuzzy teleportation does not require specific coordinates, but it is more risky, but it is generally under control. Generally speaking, mages are not willing to accept spells with too high uncertainty.

According to the position of the sun, Xia Duo roughly judged which side is south, and then flew to a high place to look at the south. The land is flat, and it seems that the end of the world can be seen at a glance.

But the fact is that human vision is limited, and it becomes blurred beyond a certain distance. In addition, there are various mountain ranges that are much higher than the height of the eyes. In fact, the range that can be seen (clear) is very limited.

Of course, Xia Duo would not fly too high, and the limit of his field of vision was probably the Wolf God Mountain in the south of the Green Pearl Forest.

According to the size and clarity of the Wolf God Mountain, the distance can be judged theoretically, but Xia Duo doesn't need to be so troublesome, he just needs to know that the teleportation is far away this time, far beyond the range of ordinary communication spells.

He tried several conventional single-person communication spells first, but there was no response from Dean, and he probably didn't receive them. If there was no communication circle at the mage tower level, Xia Duo felt that it would not be so easy for him and Niya to communicate with each other from time to time. Just get in touch.

Of course, it's not that there are no communication instruments that can be used for long-distance communication, but those communication instruments are not based on [Messaging Technique], many of them are related to projection and summoning, and some are even related to curses.

For ordinary mages, the threshold is extremely high, so it's better to borrow the communication circle from the mage tower.

Xia Duo remembered that Mrs. Patty should have a long-distance communication magic weapon in her hand, and even the Langas can reach Savile Town here, but the use of that communication magic weapon is very restricted.

At least not like the communication magic weapon made by Xia Duo that can be used at any time.

……

—— Ring 2 [Background Communication]·{Start Test}
Somewhat similar to the fuzzy transmission of [Teleportation], [Background Communication] can also be sent in a vague way, but even in a fuzzy way, it is similar to the precise delivery of big data on the earth.

[Background communication] uses the background fluctuation of the magic net to transmit information, which is essentially a super-large-scale global broadcast.

The target chosen by Xia Duo is [the south, the scene, and the image of Dean]. Within the scope of the spell, although the spell will not automatically search for the target, only those that meet the target can receive it.

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 it is not encrypted.

When there are many users, it can be difficult to find specific information.

Based on this, Xia Duo also deduced that in the future there may be monitors who specialize in the background fluctuations of the magic net.

Generally speaking, encrypted communication is still a major trend, and communication magic tools are not worried about being sold.
