Survival Base of the Trial Division, Research Institute.

Elise sent Xia Duo to the research institute and left, and then took over Xia Duo's entry process by a research assistant named "Rhodes", who is also a high-level mage.

After completing the entry procedures, Rhodes took Xia Duo to get some necessary supplies, and finally arranged a place for Xia Duo to live, and before leaving, he also reminded:

"After three days, Vice Dean Samuel will review your improvement plans, and if you can satisfy him, then you will be promoted to Level 1 Researcher and have your own independent research room."

Rhodes' words revealed envy, and Xia Duo did not get carried away because of this, he sent Rhodes away with kind words, and then returned to the room to open the mission book he had just received.

"The positioning technology based on the background fluctuation of the magic network is widely used in the field of communication and transmission?"

The task book is very informative, in addition to the specific details of this positioning technology, it also provides a variety of application scenario examples for Xia Duo's reference.

And this technology, in terms of advancement, has actually surpassed the application of the communication spell and teleportation spell that "Mercard" mastered before.

Xia Duo flipped through the mission book back and forth no less than three times, and combined with his previous understanding of the background communication of the magic web, this technology was no longer difficult for him.

The so-called "positioning based on the background fluctuation of the magic network" is actually not a unilateral active positioning, but an immediate positioning that requires the target to cooperate with the response.

When one party sends a signal, if the target does not respond, then the teleportation or teleportation is similar to the probabilistic cloud state that spreads around, and only when the target responds, the teleportation or teleportation cost will be instantly converted into a concrete event.

Before the target responds, it is possible for almost anyone to decipher and access such a signal, and at the same time access to transmit or transmit.

However, when the target responds, the person outside the target will lose the vast majority of the opportunity to crack it.

As long as both parties agree on the key in advance, the security of the transmission or transmission will be greatly improved, and most importantly -

Since this technique is essentially to locate a key with certain characteristics, it does not reveal the actual geographic coordinates of the transmission or communication target.

This plays a crucial role in the concealment of the various bases of the remnants of the Empire.

Matching with this, "Mercard" has almost no concept of positioning technology such as six-dimensional coordinates pointing to actual geographical coordinates, let alone the concept of detecting actual coordinates in a certain place.

This is definitely artificially erasing the traces of related spells and techniques.

Xia Duo went through the Arcane Empire period, and at that time there was no positioning technology based on the background fluctuations of the magic web, maybe there were, but it did not become mainstream, or it was not accessible to him at that time.

……

"How can this be improved?"

After reading the mission book, Xia Duo almost immediately thought of the communication management spell researched by the main plane Gilles Tower.

This spell was published in the Arcane Federation monthly magazine along with the [Magic Web Background Communication] at the time, and it was functionally similar to the answer interface of a mobile phone, and you can choose to answer or reject.

Of course, even if you choose to answer, you will only receive magic messages such as voice or video, not real-time communication like a phone call.

If there is no such spell, the background communication of the magic web can be used as a harassing text message.

As long as the communication positioning is not based on the key positioning, but only on the simple constraint condition, or even the acceptance condition, this is really "space broadcasting".

Ordinary people, even mages who have not mastered the spell of rejecting the background communication of the magic web, can be drowned in endless spam text messages.

Perhaps anticipating such a scenario, the Gilles Tower gave a communication management spell with the communication spell.

Now, Xia Duo didn't think of using this spell to block spam text messages, after all, most of the remnants of the empire are located by keys, which can be understood as real-name authentication, and there won't be many spam text messages.

However, since both the communication and transmission require a target response, this will waste a lot of time on the responder in practice.

……

Take Elise's Division, for example, as the Division's Director, a veteran Arcanist, and a Teleportation Mage.

Ranwen

Otherwise, those who go out on duty will not be able to contact the base when they get outside, and they will not be able to teleport back, and they will really become savages.

That is, the Elise branch has only been established for a long time, and there are only two task teams in total, like other branches, there will be full-time teleportation mages.

Including this time, Xia Duo and Elise returned to the survival base of the Inquisition Division headquarters, which was also guided by a teleportation mage.

Otherwise, even a veteran arcanist like Elise might not be able to return to the headquarters.

Teleportation mages are undoubtedly a great waste of important manpower, and day after day, they stay in the teleportation room waiting for the transmission signal, and they can't do anything.

Otherwise, if you delay important information or key transmission opportunities, you will inevitably be punished.

If a teleportation management spell similar to a teleportation management spell is introduced, allowing the teleporter mage to automatically respond to teleportation and transmission signals, then as long as he is in the base and in the teleportation room, his normal activities will not be delayed.

Just remember to keep the [Management Spell] with you at all times.

……

In addition to the [Teleportation and Communication Management Spell], another improvement that Xia Duo can think of in a short period of time is the communication lock, or even the teleportation lock.

The latter is actually what Nia is studying, starting from the fluctuation of the background of the magic web, combined with the information provided by Xia Duo, she wants to research a communication lock with a wide range and can be used by everyone.

If you add the teleportation function, it will be a kind of divine surrender.

It's just that this kind of improvement is not something that a newcomer like "McCad" who is not even an arcane at the academy can make.

Even Xia Duo can't do anything for the time being, Niya has been studying for so long, it can be regarded as a small progress, and he wants to come up with a plan in three days, which is simply unrealistic.

However, the relevant ideas are still proposed, which can more or less improve the above evaluation of "McCader".

……

Three days passed in a blink of an eye.

At noon, as soon as Shado had lunch, Rhodes came to the door, "Master McCad, are you ready?" Vice Dean Samuel will see you in Lab 003 on the second floor! ”

"Got it."

Xia Duo answered and brought the prepared "Several Application Scenarios of [Teleportation and Communication Management Spells] in the Field of Teleportation and Communication" and "Some Ideas on the Establishment of [Teleportation and Telecommunication Puzzle]", and went out with Rhodes.

……

The headquarters of the Vengeance Judgment Division, as far as Xia Duo now knows, has a total of four floors, and the lowest level of which is inhabited by a large number of civilians, including academy students, young children, etc.

McAde lived there before he became a high-level mage, and the ground floor was up, where the research institute was located, and the whole floor was there.

Before today, Xia Duo thought that the research institute only had one floor, but he didn't expect that there was also a negative second floor, of course, that was the level where the high-level was located.

As for the last layer he knew, it was the transit layer, where external teleportation or teleportation to the outside world had to take place.

Under normal circumstances, the vast majority of people in this base will never be able to come into contact with it in their lifetime.
