"Well, let's look at it the other way around. If Brokens is better defended, fewer Desibatoreans will be stationed at Brokens.

"...... So you're saying that it will be easier for the Deceiver Treasures to go elsewhere. That certainly seems to have a big impact. ......

The Desibatoreans are the largest force of adventurers in this country.
If they are concentrated only in Desibatore, the damage caused by demons will increase.
Even now, some of the Desibatoreans are fighting in other frontline cities, but if we can increase the number of them, we can reduce the damage caused by demons.

But we still need to call for help in case something happens suddenly.

When you say call, do you mean to other cities?　Even with the fastest means of communication, it would take a long time to contact cities other than Desibatore from Brokens. ......

It's true that Desibatore is far from the normal towns .
Indeed, Desibatore is a long way from a normal town, and it would take a Desibatorean nearly half a day to reach Phothren.
If you want to reach other cities from there, it will take several days.
But ...... actually has a solution to that.

We use an artifact to communicate.

"Artifacts?　I don't think there were any artifacts that could be used for communication. ......
Mercia is right, there are no artifacts that I know of that can be used directly for communication.
Communication is very important, so if there was such an artifact, it would have been the first thing that came to my attention.
However, there is one that could be used in place of .......

I have an artifact that blocks magic.

I said, and took out an anchor from my pocket.
This anchor is a counterpart to the anchor that Mercia has, and in an emergency, it can be shattered to communicate an anomaly.
This method of communication is still used to some extent today, but ...... crushing is not the only way to make the anchor's reaction disappear.

It's a good idea to have a good idea of what you're looking for and how you can use it.　You can use it as many times as you want without destroying it.

Oh. ...... That's not all. If you use that magic tool, you'll be able to communicate more accurately.

If you just want to use it multiple times, you can use the normal method of shattering the anchor, or just prepare a lot of anchors.
However, if you use [magic power blocking], you will be able to flash the anchor thousands of times.
If you do this, you will have a different use for it.

Until now, anchors have only been on and off. But if you use the [magic power blocker], you can make it blink. If you change the pattern of the blinking, you can transmit information in many ways.

In short, it's like Morse code.

"I see. ...... That sounds useful. ......

"That's not all. You can make as many blinking patterns as you like, for example, by assigning letters to it. ......

"You mean, we can have perfect communication?

Yeah. That's what I mean.

There is a time lag in the response of the anchor, and it will not be possible to communicate as much as you want, but ...... you will be able to communicate over long distances much faster than before.

This is not ...... going to change the world, is it?

Yes, it might change a lot.
But that's okay.
It's too much trouble to have to rely on birds and humans for communication in a world where artifacts are so convenient.
