ââŚBrother Jin, thatâs amazing . Thank you . â
While it was only the beginnerâs level, Elsa had absorbed Jinâs knowledge and was now uncharacteristically excited .
ââŚThe structure of matter, the reason that things fall, how planes fly . I finally understand it . â
Elsa had acquired an elementary to junior high school level of knowledge in science . So many things she had wondered about before were now known to her, and she was so happy and excited .
âAnd with that, you are officially my apprentice . But I must warn you, donât go around announcing it, alright? You must be cautious . â
âCautious⌠Should you really be telling anyone to be cautious?â
Elsa joked, which was also unusual for her .
Jin laughed and scratched his head with embarrassment before returning to the matter at hand .
âNow, the bed and blankets are ready . But we canât carry themâŚâ
They were too big to go through the carriage warp gate .
âFather, I think we have no choice but to wrap it up and smuggle it in quietly . â
Reiko, who had been silent up until now, said .
âHmm, I see . I suppose there is no other wayâŚâ
And so he decided to carry it at night with an invisible aircraft .
âI might have to make a floating base near Lake TosumoâŚâ
Laojun heard Jinâs muttering and would later go on to make it, but that would happen later on .
âSo, is this alright?â
Jin said as he looked at the blankets and bed that were to be a gift to Reinhart . Elsa looked at him and decided to ask him a favor .
ââŚJin, I too want to give a present to Reinhart . â
âYes, I see . Of course, you would, Elsa . So, what will you give?â
Elsa answered immediately .
âA mascot . â
âMascot?â
Jin asked, and so Elsa explained .
Apparently, there was a custom where dolls were given as gifts . They were meant to protect the houses of newlyweds . Reinhartâs mother had sent one when her brother, Moritz Randol von Amber had gotten married .
âI want to make a doll like Non and give it to them . â
Non was the Japanese doll that Jin had given to Elsa on her birthday . Elsa liked it very much and still kept it in her room in Kaina village .
âI understand . You should do it then . You can use any materials that you like . â
Not that it would require that much .
âI will help you if there is anything you want to know . â
âYes . I will try it . â
Â
And so Jin left it to Elsa to do it on her own, and he finally went to work on the other thing he needed to do . Modifying Reiko .
âReiko . You were watching Ehr, werenât you? I would like to add that same âsense of touchâ to you . What do you think?â
Reiko nodded .
âYes . I have no objections to what you believe is good for me, father . â
âGreat . â
And so Jin informed Elsa, who was busy at work, and then headed to his laboratory on the second floor with Reiko .
The materials he would use for the sensors was the flying membrane of a sea dragon .
 What moved the flying membranes of dragons was not muscle, but magic . In other words, you could freely control them with mana .
Once the flying membrane was spread open, it was no thicker than one millimeter, and yet it was stronger than steel . But on the other hand, it was soft and could be easily folded without resistance .
He could use this characteristic to make Reikoâs skin harder than steel and yet as soft as a baby .
Furthermore, it was known that the stretching and bending of the material caused magical energy to be released .
This was not only true of dragons, but any monster or beast that had wings .
However, the material that was available at the time was much worse than the wings of a sham dragon or sea dragon, and so the magic that came from it was weak . And so his predecessor had not thought to use it for anything .
But Jin believed that this skin could be used as sensors .
Â
âHmm . In that case, it will be necessary to differentiate between the magic from the wings and magic from Reiko . â
Jin thought about it for a while, before wondering if the pattern for the magic from Reiko and the skin might be different . âAlright, Reiko . Sit over thereâŚyes, try opening and closing your hands . â
âYes, father . â
At the same time, Jin used âTraceâ and âInspection to chase after the flow of magical energy .
âI seeâŚâ
Jin saw the very weak flow of magic that emitted from Reikoâs skin and analyzed it .
She repeated this for fifteen minutes .
âAlright, I understand it now . â
Through this inspection, he realized that the difference was apparent not in the âflowâ but in the âpotential . â
The larger the âforming,â the higher the magical potential . If he could read the magical potential, he would know the âformingâ amount, and he could calculate the power in it . Thatâs what it meant .
Jin imagined thermographic footage . It separated things by color depending on its temperature, but here, it appeared depending on how high or low the magic potential was .
âIn that case, I will need a Magi Device to read the distributionâŚâUp until now, he only needed to read the âformingâ of the body .
He was able to do it by imagining the âformingâ of the magic current in reverse, but there had never been a machine that read the distribution of magic potential .
It was something that Jin would take on for the first time, and it would bring a revolution to the automatas .
He carefully considered the Magi Sequence and constructed the Magi Formula .
âTrace and Inspection are the basics . After using them, and incorporating them once, add weight and location and calculate backwardsâŚâ
Jin muttered to himself as he slowly completed the new Magi Device .
It was a Magi Device that came from a Magi Formula that was about as complicated as a Control Core .
ââŚItâs complete . â
As if very tired, Jin muttered to himself before leaning heavily back into his chair .
âFather, you must be tired . âŚUm, it is already night time . I think you should go to bed now . â
Jin was surprised at her words and quickly looked out of the window . It was very dark .
âIt is already seven oâclock . â
Thank to the AL that emitted light automatically, he had not realized that it was dark outside .
âAlright . But let me put this on you first . â
âYes, I understand . â
It took about one minute to integrate it .
âItâs not linked to your movements yet, so it should not be difficult to move in . In any case, I want you to gather some data for me . â
âI understand . â
Reiko nodded modestly . Then Jin remember the time .
âOh, right . Whereâs Elsa?!â
He rushed down the stairs and saw the Elsa was continuing to work obsessively on her doll . âHey, Elsa . â
Jin called to her rather loudly . Elsa stopped as if she had suddenly returned to herself, and she raised her head .
âOh, brother Jin . â
âI just realized it now, but itâs already seven oâclock . You should stop for today and have dinner . â
âYes . âŚI am hungry . â
Elsa said with a slightly reddened face . She brushed the dust off of her hands and body and got up from her chair .
ââŚI feel like I understand you and Reinhart a little better now . â
She muttered, and then her face became even more flushed .
âHaha . Thatâs great⌠I think it is, anyway . â
She was saying that Jin and Reinhart often became so engrossed in what they were making that they forgot to eat dinner . And it had not been very long ago that Elsa had admonished them for thisâŚ
Â
Jin and Elsa used the warp gate to return to Kaina village .
There was about a two hour time difference between Kaina village and Hourai Island . And so it was just nearing dinner time in Kaina village .
âWelcome back, Master Jin . Welcome back, Elsa . We have just finished with the preparations . â
It was Mine who came out to greet them .
ââŚAh, I understand . This is time difference . â
Elsa was able to understand it now that she had the basic principles of science down .
Jin was sure that Elsa would be able to make use of this new knowledge, and he looked forward to seeing it .
âBrother, welcome back . â
Hanna also greeted them with a smile .
While it was a little different than Reinharts, there was also a âfamilyâ waiting for him here . And thinking about it made Jinâs heart feel warm .
