Dungeons for the Devil, Dungeons for the Core (Book Version Title: A Different World Dungeon Made with the Devil)

Are you guys...?

It was the three spirits, the "Three Pieces", who were fully open to Nakatsugi disease as dungeon master apprentices of the "Mai-no-Hideyosho" who raised the famous accusation.

And the proposal was appropriate for the patients with Necrosis Disease, but it seemed promising.

Do you want to extend the underground tunnel for interception under the town...?

”Along with that, I'll also use it as a passage of magic power... huuh...”

The military advisory groups such as Peter and Ness are also admired - or dumbfounded - for their unexpected ideas. Not to mention the reactions of the Conscientious, but the Nakamichi, headed by Keane, was overjoyed. It was a crowe who was already worried about it, but it was also true that the three-piece proposal was a shame to kill.

Odrant is a vast dungeon.

I heard that your Majesty (Majesty) helped me to keep the secret safe.

If you do it with that kind of help, you'll have a good plan.

The three-piece proposal is, in short, the installation of a voice tube. It has already had a track record of operation in the Shard's covert dungeon, and is still listening to rumors about the Illustrious soldiers stationed there. I was concerned about the value, but the cost of building it - in Crowe's subjective opinion - was significantly lower. In order to determine the position of the voice pipe piping, it is necessary to explore the arrangement of houses in the town in advance, but on the contrary, it is about that much trouble. If it is a tunnel of a human scale, you will be aware and vigilant, but if you are using a spirit, something like a very narrow crack will be enough. Then you won't be noticed, will you?

More! If you tunnel in each dungeon under His Majesty (Majesty)!

It's possible to build a huge intelligence network underneath Theodorum!

In addition to knowing what's going on in that country in your hands, can you solve the magic circulation problem?

No... I can't even build a tunnel network overnight.

"Is it possible if it is not done in the morning and the evening?" No one will stick it in anymore. Isn't that what you can do?

(As for Theodorum, it's the practicality of the intelligence tunnel right now......)

The question is whether it will yield enough results to deploy personnel.....

(...... even if it is of low value as an intelligence base, can it be expected to serve as a passage for magic and spirits......)

It was a magical passage that was a condition for the spirit gate, but it could be formed by any method other than planting trees. On the ground, magic power dissipates immediately, unless there is a structure to suppress it. This is why caves and ruins tend to become dungeons, and if you consider this, it seems that there is enough computation to restore the magic circulation through an underground tunnel.

Hmm... it's an interesting idea, but I need to experiment somewhere.

It was Crowe who thought that there was no affordable place.

(...... speaking of tunnels...... there was definitely something about the Spirit Gate of the "Rotten Hut"......)

When the Spirit Gate was built on the outskirts of the village of Bezin in Islamaphan, it seemed that the spirits entering and exiting the gate were witnessed by the villagers, and it seemed that there was a fuss with the human soul (a duma) of the ghost fire. This is embarrassing. In the meantime, I extended the underground channel from the spirit gate in a way that bypassed the village of Bezin, and then connected it to the small animal's nest in the cave - already abandoned - to deal with it......

(...... Do you want to extend the intercepting tunnel under the village? After all, I have to check on the situation once... can I have the spirits check what's going on with the flow of magic power...?)

If you like, you can capture the intelligence hub and magic aisle all at once. If you combine it well with the corridor of magic by planting trees (Corridor), the choices will spread a lot.

This should be tested with temper.

There were a number of developmental plans, and it was a crowe that I really liked... but when this happened, I wanted to scratch my greed to see if there were any other good ideas. There is no mud under the willow, and it is an anecdote of the Song people who protect the stocks they learned as students. [Rabbit's Roaring Nekko] comes to mind, but it's good enough to ask.

Ah... do you have any other suggestions?

- To my surprise, I got a reply.
