The person I'm communicating with is Doran.
　Doran has the job of understanding exactly what magic tools I want to develop and communicating the finished product to Paula and the others.
　Until now, there haven't been a lot of magic tools that I wanted, so I never asked him to do this, but....

　Well, since we've allowed them to develop whatever they wanted until now, the skills of the employees of the Technology Development Department should be reasonably high.
　The first of them are Paula and Lisian, Lyna has the idea of being a reincarnated person, and after all, Toretto-san is here this time, so the possibility of developing it is extremely high.
　With that in mind, I decided to send a reminder to Doran.

'Dolan, can you hear me?'
　Thanks, I'm not very good at telepathic communication, so that's out of my voice.
　As I waited with that in mind, I received a response a little while later.

I'm sure you'll be able to find out more about this.
I have a mage that I need you to make as soon as possible.
'Oh! Unusual. And what exactly do you want me to make?　There's plenty of ore and magic stones to spare, so I'm sure you can make most of them.''
　You seem very happy about that. I thought Dolan wouldn't show much interest in magic tools.

It's not just a matter of time before you'll be able to get your hands on a new one. Something that can be sorted out even if the demon race is transformed.
''Unu ... it's difficult, but there's nothing we can't make. But if we still activate the Sanctuary Barrier on the city, even if it's still a village, won't we be antagonizing the Adventurer's Guild?''
　Hostility is not a gentle thing to say. And with the Adventurer's Guild........

What makes you think that?
''Certainly, if we can activate the Sanctuary Barrier in the village and town, the demons and demonkind will not be able to get close to it. But what happens to the corpses of the demons and the parts and materials that are proof of defeat?　Won't it burn?'
Ugh, I wasn't thinking that far ahead.
　I don't think even the corpses of demons can burn, but I'm not sure it's ever going to happen.
　And I forgot that there are demon users (tamer) in the world.
　I thought I had good intentions, but it doesn't mean I won't create an unnecessary spark.......
　I guess it's one thing for me to develop new magic on my own.

''Luciel-sama, you seem to be lacking a bit of composure. What's going on?''
Yeah, actually...
　This is how I told him about my visit to Nerdal.
　And this time I received a simple reply of approval.
'....I see. I understand very well. I'll get right to work.'
Well, can you do it?
''I can do it. A magic tool similar to that already exists from the beginning. I'm sure the Holy City of Surur has a similar mechanism. Well, it's not working right now.
Oh, okay.
　It's obvious, but there have always been ways to keep the demons away, right?
　And Lord Leinster thought the same way and laid a ward in the holy city of Surur, didn't he?
　At the time, I thought it was another dimension of existence, so I completely forgot about it.

''I just need to improve it. However, it uses quite a bit of materials and magic stones, so can you prepare it for me?
''Is the magic stone I gave you yesterday not enough?
'Not enough. Of course, if it's just Yenis, there's no problem, but it's not quite enough to protect the villages and cities that exist in every country.'
　...Oh, I see. If I told you that I'm going to protect the town and village, of course you'd make that decision.
　Well, if you want to gather magic stones and materials, you can gather them if you want to, and if you think of it as an advance investment for the peace that will eventually come, it's a small price to pay.
I understand. Then I want the entire technical development department to work on the development of this magical tool.
"Awesome.
　That's where I ended the communication.

　The water spirit and the dark spirit still seemed to be investigating the six people who had been turned into demons, so I decided to ask them about the summoning magic circle.
''If I improve this summoning magic circle, is it possible for me to summon something as well?
'I think I can do it. It looks like this magic circle is an improvement on the magic circle originally used to summon heroes from the other world.
　I wonder if some of the brave men and women have been called from Earth to this world?　Too much of Lord Leinster's track record or too great, and even if he was there, he'd be in a complete haze and wouldn't be able to follow his tracks.
　As I was thinking about that and looking at the magic circle, Lydia came over at a small run.　　

''Luciel-sama, I've found out about those people.
I'm listening.
'First of all, the country those men served, but they were researchers sent from the Duchy of Branges, the Kingdom of Rubruk, and the Empire of Ilmassia.
Disconnected?
　I look again at the clothes of the demonized ones, but they are wearing the same robes.
　But since the two of them are wearing armor, are they in a position to be guards?

'Yes. And surprisingly, I had no memory of the last few months.
'Does that mean you were fascinated or brainwashed?
　
　If we respond poorly, this time they'll drop us.

''I don't know the details, but the Water Spirit-sama and Dark Spirit-sama are like that.
That's why it took you so long to gather the information.
　I didn't know how strange it was.
　I can't believe it's taking this long when I have the ability to immediately see into the future and peer into my memories.

''So, but you said that there was a demon race when Luciel-sama fought, right?
Yeah, two of them. The Holy Dragon swallowed them both and purified them from existence.
"...I hope I'm wrong, but maybe one of them is my brother.
How did you come up with that?
　I did the same to Lydia, who had a sad expression on her face, as much as I could.

''The Spirit of Water and the Spirit of Darkness tell me that there seems to be a dinner party hosted by my brother and Lord Camilla in the fragments of my memory, and I seem to be missing the memory of what happened afterwards.
　You mean that Lord Kamiyah was here in Nerdal?　But Brange's researchers didn't say anything like that, did they?
　They seem like a troublesome opponent, and I'll just act on the assumption that they're alive.

''So you don't know why we're here or the purpose of drawing this magic circle?
He's trying to restore that missing memory now, but it's not working.
　Then there's no reason for me to be here anymore.

''Well Queen of Spirits, may I ask you to take care of Nerdal and the inhabitants of Nerdal?
'Yes. That's fine, but do you have any ideas?
'No, but we're going to fall behind if we don't, so we're going to prioritize raising our strength as much as possible.
　Even if you think about it, I don't have the power to see everything or develop anything.
　The only thing I can do is heal people's injuries.
　But if I can help my masters raise their level of performance, then all I have to do is simple things.

''I see.''
''Besides, this Nerdal has the World Tree, and with it being protected by the Spirit Queen and the Great Spirits, even the evil gods won't be able to touch it so easily.
　The Spirit Queens will put the World Tree before the inhabitants of Nerdale.
　But Nerdal is a place that you have fond memories of building with Lord Leinster, so I'm sure they want to protect it.
　If that's the case, I'll ask him to protect the residents as well, and I'll concentrate on what I can do to make good luck.

I see........I understand. We'll protect you here. I expect you to defeat the evil gods as soon as possible.
Don't get your hopes up there.
　I'm sure they can see through my intentions.
　But I'm sure he understands that the situation won't change even if I'm the only one struggling.
　If my masters are on the same level as me, even if they are a small group of elite, they will be able to control Brange.
　Now it's just a matter of how many trump cards you can prepare against the evil gods, but the best thing you can do right now is to increase your odds of victory as much as possible.
　I bowed to the spirit queen with a renewed resolve and moved to Yenis with Lydia.
