Chapter 319 – The Shackles of Magical Tools

After the instructions and introductions for the Demon-Slaying Knight Order, the subsequent social gathering disbanded in the early afternoon. Elliot immediately went out with Camilla to look at potential new homes.

Regarding the shipyard, aside from the cafeteria, the interior and furnishings were not yet complete. Once those aspects were in order, the training for the Demon-Slaying Knight Order would likely begin in earnest. At that time, we would also proceed with preparations for the full moon labyrinth for the party members in parallel. It should serve as a good example for how to use aerial combat gear.

As for the airship’s keel and exterior, the materials had already been brought in, so it should be possible to start constructing the airship’s exterior around the same time as the training.

The Demon-Slaying Knight Order would also be boarding the airship as crew. I think the environment of being able to train while watching the airship being built from the corner of their eyes would be quite motivating.

Now then. We returned home and decided to relax in the game room while discussing the magic tools to be installed on the airship with everyone, including Alfred and Viola.

In the game room where Irmhild and the others played music, we spread out blueprints and took notes while drinking tea.

As for me, I proceeded with the meeting while writing down recordable spell formulas on paper.

“You mentioned changing the properties of magic stones and fixing them… Does that mean you can also create magic stones with properties similar to Claudia, Irmhild, or Seraphina?”

“Yes. It should be possible to adjust the quality of a magic stone to resemble someone’s personal magical aptitude. Changing a magic stone’s properties and fixing its element involves pouring magical power into it while using a spell formula.”

Valentina nodded but added, “However…”

“Turning a race-specific technique into a magic tool… Wouldn’t that be difficult since the spell formula isn’t established?”

“There’s no need to worry about that. Even magical power usage methods not found in existing spell formulas can be recorded for incorporation into a magic tool by, for example, having Seraphina use her technique while I directly observe how she moves her magical power with Circulating Ki.”

Since it’s a magic tool, its actions become somewhat fixed, so it won’t be as free and versatile as Seraphina’s sound manipulation.

Output Irmhild’s Cursed Melody using a wind magic stone, and give it directionality using sound manipulation from a magic stone imbued with Seraphina’s characteristics… Yeah. The mechanism of the sonic cannon itself should be fine.

“…I see. So by sensing the flow of magical power with Circulating Ki, you can also see how to manipulate it. That’s a convenient thing.”

“Until now, we could research and record spell formulas… but the more we tried to do advanced things in the process of utilizing them, the more problems arose.”

Alfred nodded at my words.

“There’s also the issue of magic stone capacity, and it felt quite difficult to utilize them as magic tools.”

“Same with treating them as magic. Special techniques are meaningless with just the spell formula if the magical aptitude doesn’t accompany them.”

What proved practical were items like the Amulet of Evil Repulsion, for which we obtained established production methods from BFO… But even that is a consumable specialized for a single function—anti-curse magic—as a magic tool, and it shatters after blocking curse magic a few times. It’s undoubtedly excellent as countermeasure equipment, though.

“So, with the addition of the technology to change magic stone properties, various shackles have been removed.”

“That’s right.”

When I answered, Valentina smiled happily. The scope has broadened, so applying it should allow for various things.

“Surprisingly, old magic tools with unknown production methods might have been made that way.”

When Grace said that, Rosemary nodded.

“I see. In an era when more people could use Circulating Ki, it might have been possible to turn the unique skills of monsters or specific races into magic tools using the same method as Theodore…”

“…It’s only natural that valuable magic tool production methods would be kept secret. As a result, the methods also get buried.”

Old Sigmund widened his eyes in admiration at Rosemary and Claudia’s words.

“…Hmm. That line of thinking might be correct.”

“With the help of the labyrinth village residents, we might be able to create various magic tools.”

Somehow, a hypothesis was formed in an unexpected direction.

Ouroboros… At the very least, it’s certain that someone who could use Circulating Ki in its production was involved. It might be an item originating from the Seven Sages, but well.

“Well, it seems we’ve strayed a bit from the topic. Let’s return to the airship discussion.”

“Then… regarding the sonic cannon’s targeting?”

“Ah. We succeeded in an experiment on that. We managed to project the doll’s field of view onto a crystal ball. Just as Theo-kun said, when we thinly stretched Mithril Silver and directly connected the doll and the crystal ball, it solved the distance and capacity issues too. But… since what’s projected is spherical, it distorts a little.”

“Maybe making the crystal into a flat panel would be better.”

In short, it’s magical power transmission wires and a monitor panel. Since Alfred’s experiment succeeded, that should resolve the issues with the sonic cannon’s targeting and external monitors.

For long-range reconnaissance, I’d like to mount telescopic magic tools as well, but since those can be recorded as spell formulas, there shouldn’t be any particular problems with implementation.

“Next, we need a mechanism that can rotate a certain range up, down, left, and right.”

“That kind of mechanism… would be Viola’s jurisdiction, right?”

When Alfred broached the subject, Viola nodded.

“Leave that to me. Not just me, but we can also borrow the wisdom of Miriam-san and her master acquaintances. That kind of fine craftsmanship is a Dwarf’s specialty.”

Saying that, Viola lightly tapped her chest area. Mhm. That’s reassuring.

“What about the propulsion devices connected from the armor plates?”

“Normally, they take in air from the front to assist the Air Blast and expel air backward for propulsion. In emergencies, they use the magical power converted by the armor plates to mix fire magic expelled backward for instantaneous acceleration. When not in use, we can probably store it in as large a magic stone as possible.”

Sonic cannons, propulsion devices, and… many defensive devices.

Since we’re fighting demons, I’d like one more trump card… but if it’s a simple weapon, when it spreads, the people without countermeasures will be in trouble, so it’s quite difficult.

If defensive devices are fine, there are ideas like covering the ship’s surroundings with steam or illusions, or refracting light to make it invisible… If it can’t be seen visually, it would undoubtedly be powerful for reconnaissance.

Then, Elliot and Camilla returned.

“We’re back.”

“Welcome back.”

“Did you find a good property?”

“Yes. There was a quite good place very nearby.”

Camilla, asked by Ashley, exchanged smiles with Elliot, creating a harmonious atmosphere.

“We also ordered furniture. We’ve arranged for it to be delivered.”

“Once the inside is tidied up, please come see it.”

“Yes, definitely then.”

When it actually comes to moving… given Elliot’s position, it’s probably more prudent for appearances to wait until after marriage. Until then, I think it’s fine for him to stay at my house without hesitation. It hasn’t been that long since Elliot returned for Ashley either.

“Elliot’s house, a basement?”

Then Sheila asked. This is… not “Is there a basement?” but “Aren’t you making a basement?” right? She said it while making eye contact with me.

“We’ll make one if necessary, but…”

“Is that okay?”

Elliot’s expression brightened.

“Yes. If Elliot-san is fine with it. It’s not much trouble.”

“Since Camilla is here too, having one would be reassuring… May I ask you to do it?”

“Understood. Then let’s find some free time and do it later.”

“An alarm device would be good too. I’ll make it. If linked with a communication device, you’ll know immediately if something’s wrong no matter where you are.”

“Then we’ll need dolls for security too.”

Alfred and Rosemary also seemed enthusiastic about strengthening the security measures for Elliot’s house. Surprisingly, both seem to be getting carried away, thinking ‘might as well.’ Rosemary seems to be smiling, but she’s hiding her mouth with her feather fan.

“I shouldn’t just be protected all the time; I need to regain my senses so I can move when necessary.”

Camilla said. Like Elliot, Camilla seems to be a smallsword user… but she probably has a long gap since she last practiced. Hmm. Smallsword, smallsword.

“Will you train with Mihaela-san and the labyrinth village residents? Also, with aerial combat gear, you could escape by flying through the air if something happens.”

“That might be good.”

Elliot and Camilla nodded with bright expressions. Marlene was also smiling happily. Since she’s honing her smallsword skills with Mihaela, she might be pleased that the number of participants in training is increasing.
