04-05 A gearbox, a magic turbine, and…
The next morning, after Jin woke up and had his breakfast, he began making a gear .
First, he created a linear gear as a reference .
First he prepared a straightened adamantium strip, then he made the teeth of the gear . He didn’t worry about the module (the size of the teeth) . This is how Jin normally works . (TLFalin: It actually says module and has the part in the parentheses, it seems the author researched this to give a more authentic explanation, so there may be more as the chapter progresses)
「Is this much good?」
Because Jin plans to use it for a car, it needs to be strong, but since he’s using Adamantium, it’ll be work well at a small size . Although it’s simple to make it big by itself, Jin decided to start from something small .
For the time being, he made 200 copies of his first one . These were made without difficulty .
If lined up face to face, it becomes immediately apparent that the spacing of the teeth is the same and they’re all identical .
「Well, if I can make do with one band, and . Could I… yes, I can do it!」(TL: He’s muttering, so this was hard to translate)
He completed the teeth on the linear gear .
「After that, yeah… make a gear with the number of teeth that I need to fit this . Yes, it’s a success! Now, into a circle . I think I’m done with the outside of the gear with this . 」
At this stage, he has a gear with his desired number of teeth . It is, so to speak, a doughnut with teeth .
「Now, to fill the inside circle of the gear, . Great, it worked!」
In front of Jin laid a completed spur gear .
When Jin made another gear with a different number of teeth and tried to engage the two, they engaged so neatly that Jin began to feel like dancing .
If a spur gear is made, Jin can make a bevel gear somehow as well . However, it will be limited to the same number of teeth .
Still, it was fascinating that it could change the rotation 90 degrees, and it would quickly increase the kinds of machines Jin could make .
「Yosh, let’s make a car!」
He made the chassis with light silver and got carried away and made a 4 cylinder engine, no, a 4 part engine . The tires are made neatly from rubber and in the afternoon the car is completed .
「Un, un, it’s nice . 」
Because there’s no transmissions, it can only be operated by an accelerator and a brake, so it’s not automatic . Because the output of the golem is constant, it can work .
After driving around in the flat area in front of his research center, Jin got off satisfied .
「Father, I feel that the golem horses were more versatile . 」
「Huh?」
Jin couldn’t understand Reiko’s question for a minute, but shortly after realized the implications of it .
The airplane had a and the ship had a
Although Jin had thought of the golem engine for land that’s paved, he forgot that most of the world hasn’t been paved .
How much time until it’s a cars turn in this world?
「Hmm, did I become complacent? Well, it’ll work for this island . 」
Was said,
「Reiko, have Topaz make a road network on the island . You don’t have to pave the surface, use , It’ll prevent the weeds and also allow something heavy to go across it . 」
「Yes . Should I give priority to Tatsumi Bay, the fields, and the airport?」(TL: Was it called Tatsumi Bay in a previous translation? I’ll have to come back to this . )
「Ah, yes, please . 」
Because I made the airport for the airplane, the maintenance of the road was urgent business . A large Warp Gate is installed at each place as well, but a road is still necessary .
「Aaah, I’m hungry . 」
It was already pitch black out .
「Father, I made dinner today . 」
「Ah, Reiko, I’m looking forward to it . 」
Because Soleil and Luna were busy mass-producing the airplanes and ships, Reiko took charge of cooking for Jin .
「It’s pure white bread, isn’t it?」
「Yes . 」
Reiko peels the wheat, one by one, and the bread was made with the ground down flour .
「Mmm, tasty . 」

Jin eats the bread and has vegetable and fish soup, after all, the bread without the crust is is more delicious when mixed in .
「I’m sorry, the rice hasn’t been found yet . 」
「No, I understand, I’m asking for a lot . I’ll search for it in the western country I’m going to this time . 」
Since they couldn’t find rice in the port town, Port Rock, Jin thought they might find it in a western country where the things might be different and unusual .
7 days since he returned to Hourai Island…
「Might as well make a turbine . 」
The first day Jin began with the lines . The principle was simple, to put an impeller in a sealed container and turn it with wind magic .
Since wind doesn’t need to be taken in from the outside it circulates well and doesn’t leak, so it can be done easily .
「Oh, the number of revolutions is high as expected . 」
Because it’s basically a windmill, the rotation speed is high . On the other hand, the torque is inferior to a golem engine .
「Oh well, it’ll be useful for something . 」
It was fun to make .
Reiko savors the significance of being near someone like Jin .
The data of the work Jin completed is also saved in Reiko, and it’s put in order and preserved so that it may be possible to reproduce at any time . It is the role of an auxiliary storage device for Jin .
「Father, what happened to the talk of creating a weapon?」
And, like a secretary, she points out what Jin forgot .
「Oh, did I say something like that? It will be necessary for the defense force . 」
Jin said and then was lost in thought
「, and …」
He decided to make a laser standard equipment .
The reason being that it’s easy to make non-lethal if he changes the strength . Although the defense method is limited, it’s easy to aim and hard to make . (TL: pretty sure he’s talking about for others, so if one gets lost, they can’t just reproduce it) .

「Ok, I should be able to make it like this . 」
Jin has Reiko get the materials right away so he can begin manufactureing . The structure is simple . In the form of a thin flashlight, he writes the inside . (TL: is it just me, or is he making a light saber?)
「Ok, now for authentication . 」
「Father, what is authentication?」
Reiko asked about the unfamiliar words .
「Ah, let’s say, for example, you lost it and someone else found it, it still won’t work for that person . 」
Without Jin’s magical power waveform it won’t operate . It was name magic waveform authentication .
Because all the golems and Reiko inherited Jin’s magic waveform when he made them they can use it without a problem .
「And that’s done . 」
The prototype was completed . It looked like a tube and wasn’t of the pistol type . (TL: I guess it’s not a light saber)
「Do you want to try it?」
They go outside of the laboratory and aim at a pile of rocks at the edge of the open space and fire the laser .
Thin rays the size of a needle pierce the rock in a few seconds .
「Yes, a success . 」
Jin changes some of the settings while saying so and prepares to fire once again . The range is short, which slightly diffused the rays, but the rock was vaporized immediately this time .
「This is dangerous, we shouldn’t use it except in an emergency . 」
Jin said and decided to consider another low power weapon .
「How about paralysis… . a stun gun!」
When Jin first met Beana in the Blue Land, she had a “Paralysis Cane” . This allowed him to understand that such a magic tool already exists . (TL:Was it called a Paralysis Cane before? Oh well, I’m going with that for now . )
「Well, I’ll make something a few stages above that . 」
Jin was enthusiastic but…

「Father, it’s almost time for lunch, please make sure you eat . 」
Reiko told Jin and he obediently left the research center and went towards the house .
「Did Soleil make today’s lunch?」
The menu was toast, citron marmalade, a salad, and eggs sunny-side up . Although it looks like breakfast, Jin doesn’t worry about it and eats .
「Gouchisousama . 」 (TL: Although I figure most of you know this already, it’s a formal way of saying thanks for the food after they’re done eating, no real translation for it though . I could just put “thanks for the food” or “I’m done” but I think I’ll leave it at that . )
Immediately after eating, he headed back to the laboratory .
「As usual, when it is about making something, father always lose sight of his surrounding . 」(TL: Thanks to T . Y . for helping with this line . )
Reiko followed immediately after Jin to help him .
The stun gun was easy to complete, because he had looked at the “Paralysis Cane” before . He resolved some of the faults and improved the efficiency .
Its looked similar to a wand and was about 30cm long . He also made 2 police baton type ones as well . The wand was for self defense and the baton was for security .
The wand was made of light silver and the baton was made of a mithril and adamantium composite .
「Since it’s come to this, I’ll also make an army . 」
Jin said so and made 20 golems and name them from 1-20, Land .
With this, Hourai Island’s armed forces were completed .
