Meanwhile, by then, Noir and Alexia had both been packing their rooms since the morning and had been working on the development of new magic instruments and movable prostheses.

I have to say, it was these two who brought home the biggest harvest in this incident.

Even though ancient magical civilizations that once flourished on earth did not reveal the whole story, a glimpse of one end of the technology at the time is an unusual harvest for them.

Numerous technologies used, ideas and perspectives of product development, and manufacturing machines to realize them.

They were well above contemporary standards, and even if they were incomplete, they were all knowledge that would undoubtedly improve the living environment of the Kingdom.

However, it is difficult to think about reproducing all of the knowledge brought back at once, and it is the main thrust of the work that the two of us are working on now that we will gradually and steadily realize it.

"Small things, tricks from where you can. It's easy to say with your mouth, but you'll be in a hurry if they show you that."

Alexia smiled joyfully while playing with the internal mechanism of her prosthesis on the workbench.

"Whether you look to the right or to the left, there's a lot of lost technology. Digits from the level of infrastructure as well as tools. There are a lot of things I want to reproduce, but I don't have enough time or cost, and above all, there is only one body. A happy scream is exactly what this is about."

"Ah, ahh... really... it was an amazing sight..."

Noir also smiled at his mouth, empathizing with Alexia's feelings.

I'm just remodeling the internal magic that moves the prosthesis, but if the magic expert saw this work, he must be surprised that the magic transfer mechanism is extremely efficient.

Among the many pieces of information obtained from the world of ancient magical civilization, the first thing they were trying to put into it was a mobile prosthetic limb, one of the state-of-the-art technologies.

As the War of Continental Unity rallies and the battle against Agart Lam is expected to intensify, the demand for high-performance prostheses to regain lost limbs by function continues unabated.

Higher performance, closer to the original arm, even returning to active service.

The required performance from society is the blue ceiling.

Technological sophistication considered necessary for realization is also the highest.

I can't think of anything more than putting in the harvest that was brought back from ancient magical civilization first.

"... now that your prosthetics are getting lighter... don't go any further..."

"Weight, Performance, Strength and Cost. If you stand over there, this would have been a typical example of not standing up."

"I can't believe that... in such a way... you can simplify the structure... while maintaining its strength..."

"The method of improving the strength of the parts is also called scaling from the eyes. While halving the weight of the joint mechanism, the strength will improve rather than stand still, which is really bad."

Noir and Alexia, without stopping their work, exclaimed their admiration for the performance of the new technology they were putting into their prostheses - ancient in time.

It is desirable that the weight fits within a range that does not differ significantly from that of the living arm, rather than fitting as an arm.

However, if you want to be able to move in the same way as the living arm, the internal mechanism will inevitably be complicated and the weight will increase, and the overall strength of the prosthesis will decrease if the non-mechanical weight is reduced.

If we want to solve these problems all at once, we need to use a lot of rare materials, like the prostheses Luke is wearing, and the manufacturing costs jump at a level that prevents their spread.

However, by putting the lost technology of ancient magical civilizations there, it is possible that this dilemma will be solved.

"Instead... in this case... weights, weights, weights are necessary to balance..."

"Hmm... when arming a boulder, it's unlikely to go 'like a living arm'. It's a weapon, so you have to cut it off, so this time it's a civilian product... will you finish it in a normal way that will naturally lead your everyday life?"

"Ji, in the accident, I lost my legs... my arms... because there are people... unexpectedly..."

"You're surprised at the Green Hollow, too. Something like an accident when you cut a tree, something you did while you were hunting."

Eventually, a single prosthetic hand is finished by the joint work of the two.

It was thinner than what Luke was equipped with, and had an overall feminine curve.

It is a flat specification with no weapons, and the design has the highest priority of being able to be used as usual.

"Yeah, perfect! But when the finish comes this far, you'll finally want to reproduce your tactile senses. It seems like it can be realized by applying a five-sense connection with the user demon, right?

"In theory... but I don't know if it's going to work..."

"The next research theme is decided! There's no magic around here, because you can't stand up, and you really expect magic."

"Well... it's hard to drop magic into a magical instrument... but... it's worth trying..."

Noir had a smile that he enjoyed challenging difficult topics while pretending to be bothering his head.

"In the meantime, would you like me to test him for today? Say hello to your sister."

"Ah, ah... okay... I'll be right back..."

"Take your time. I'd like to rest for a while."

Alexia packed her prosthesis and pushed it into Noir, pushing her back out of the room.

Noir was reluctant at first, but Alexia ran away in a rush to find out if the door to the room had been closed lightly.

"Absolutely, it's a good excuse to see my sister, so don't hesitate to come."

Bran, Noir's twin sister, was hostile to humanity in the Demon King War for good reason to survive.

Originally, it was a position where capital punishment was possible, but after a tortuosity, it calmed down in the form of "being imprisoned under the surveillance of the Knights of Silver Wings, while engaged in labor to assist in the creation of magic equipment for the White Wolf Shop."

Of course, Noir, who is in charge of magic equipment, will be the main contractor, and bringing in the work is a great opportunity to honor the incarcerated sister.

"... well, I haven't seen Julia either, so I can't say anything great. You're hesitating, I knew it."

Alexia, recalling an old friend in a situation similar to Blanc's, quickly headed towards the living room to pick up some tea snacks during the break.
