âFather, the arrangements for lunch is done . â
Reiko informed the group while they were relaxing on the beach, looking at the sea .
It was a few minutes past 1 PM . That is after taking the time difference between Kaina village and Hourai island into consideration .
Â
Sheets were laid out on the beach for them to sit, with the baskets just beside them . Even a tarp was set up .
A tarp is a cloth used to block the sunlight . Itâs usually set up using simple props and the tension of a rope .
It was already June and, as Hourai island was located in the Northern Tropic, the sun was blazing down on them from above .
âOoh, now this is comfortable . â
As the tarp can block off sunlight very well, it was refreshing underneath it . Sun shades are quite important here as the temperature is higher near the coast .
âEveryone, there are many different items so please feel free to choose whatever you like . â
Reiko said, opening the lid of the basket .
âOohhâŚâ
Sandwiches, smoked meat, boiled egg, pelshika and citran, each of these were put into different baskets .
And inside the last one wasâŚ
âOnigiri?â
Onigiri, seasoned with salt and wrapped with edible seaweed .
âJin, whatâs this?â
Reinhart asked with a curious expression, looking at it .
âAhh, thatâs called âOnigiriâ . Itâs made with cooked rice and wrapped with âlaverâ, a kind of seaweed . â
Â
Saying that, Jin was the first to take a bite into the onigiri . Reiko, who had been observing from the side, poured him tea from the thermos flask .
One bite . These onigiri which are seasoned with Hourai islandâs seaweed salt are tasty by themselves .
âHmm, tasty!â
Saki was the second to try it after seeing Jin happily stuff his cheek with onigiri . She took a bite and said,
âOhâthis really is tasty . Itâs simple but has a profound flavor . â
Hearing that, Elsa, Reinhardt and Belche also tried it .
Itâs black on the outside because of the seaweed but pure white on the inside .
âJin-nii, this is tasty . The scent is also nice . â
âOhh, it truly is! This is⌠awn⌠no, rice!â
âJin-sama, unlike its appearance, the texture and taste is quite something . â
It seemed the 3 of them truly liked it . Jin was happy that they liked the taste of seaweed .
âThank you . Itâs the taste of my homeland⌠Reiko, it was Laojun who did this, right?â
Jin asked with a grin . Laojunâs surprises are somewhat bittersweet since they remind him of his homeland .
âYes, father . â
âI see, as I thought . Itâs delicious . â
Jin gulped down his fourth piece .
âThese are also delicious . â
Belche said while having a sandwich .
âThese boiled eggs are so good, even though itâs just normal boiled eggs with salt . This salt is not our usual salt, is it?â
Reinhardt tried out the boiled egg and was surprised by its good flavor .
âWhich one, which one? âŚâŚHmm, Jin, this isnât some normal salt, is it?â
Saki also supported Reinhardts claims . They are quite sharp .
Â
 âYeah . Thatâs seaweed salt and can be harvested around this area . â
Jin answered, pointing at the Tatsumi bay .
âYou make it by burning the seaweed gathered from here, then dissolving the ashes in water and desiccating the clear top layer of the liquid . â
âHmmm, if you do that, does that mean thereâs something mixed in here thatâs in the seaweed?â
âExactly . Itâs salt with the umami thatâs in the seaweed . â
Although the taste gets dull if itâs used inappropriately, it seems it goes quite well with boiled eggs .
âBy the way, the salt used on the smoked meat is also harvested from this sea . â
âItâs such a clean sea, after all . â
As Saki said so while looking at the sea, Aqua suddenly emerged from it . Number 33 .
âUwaah!â
Saki was so surprised that she toppled over on the sheet . The others were also considerably surprised but not as much as her .
âThatâs Aqua, a golem maid . Itâs in charge of ocean development . It seems it has just harvested some laver . â
Â
As Aqua had just suddenly appeared with the laver that they had all been having, all of them unanimously looked at Aqua 33âs hand .
It was holding a large amount of dried laver .
âThatâs seaweed?â
âIt actually is sea weed, huh?â
âHow do you process that to make it edible?â
As expected, it was Saki who came asking the recipe . Jin answered her question .
âAfter cleaning and drying off the clean sea water, itâs minced and put back into normal water . Afterwards, itâs filtered with a wooden flask and drainboard before drying again . â
It was quite an abridged explanation but Saki was able to somewhat understand the process .
âI see . So, basically, after slicing them up into small bits, you flatten them out and dry them, right? Interesting . â
 It was at this moment that Jin had decided to discuss paper making with Saki later on .
After lunch, when they were having fruits, Hydro 2 and 3 returned from outside .
Reinhardt had ridden them before once during the turmoil caused by the Unifiers but Belche and Saki were seeing them for the first time .
âJ-Jin-sama, what is that ship?! Itâs moving without an oar or a paddle!â
As expected, Belche was surprised seeing the Hydroâs propulsion system, as she was somewhat knowledgeable about ships .
âItâs called the Magi Water Jet, it moves forward by gushing out the sea water . â
He explained it quite simply but Belche was unable to comprehend it .
âMarine 2, 3, are you done with todayâs patrol?â
They answered in the affirmative to Jinâs question .
âYes, my lord . â
In reality, it was Laojun who skillfully handled the scheduling without even letting the Marines know .
In the first place, it was weird for them to return here, at the sandy beach, even though the bridge is just some distance away .
Of course, Jin too noticed this but didnât say it out loud .
âIf so, would you give us a little ride?â
âYes, anywhere, anytime, as long as itâs your order, my lord . â
The Hydros were 4-seated . As the Marines were handling the ship, Jin, Elsa, Saki and Reiko (Reiko could fit since she was small) boarded Hydro 2 . And Reinhardt, Belche and Neon got on Hydro 3 .
Â
Unfortunately, Aal, Edgar and Noir had to stay back this time .
âAlright, letâs go . â
âUnderstood . â
And like that, Hydro 2 and 3 started moving .
âO-o-ohh, this isâ!âÂ
Saki was amazed by the acceleration .
âKyaa! What is this?! This speed?!â
Belche was also astonished .
âHmmm, this really is amazing!â
Even Reinhardt, who had ridden it once, couldnât hide his surprise .
âI would also like to try building one but I should start with a paddle steamerâŚâ
Reinhardt was well aware of his abilities .
Hydro 2 and 3 were moving at about 50 kmph .
âJin-nii, this is really fast . Amazing . â
Elsa said, feeling refreshed with the sea breeze .
The ebb and flow difference in the seas of this world is small since the moon is small .
Moreover, as occurrences of typhoons are comparatively low, the seas here are also gentle .
Â
And today as well, the movement of the waves were gentle . Catamaran-styled Hydro displayed impressive stability with speed .
âJin, this feels really good! This ship is amazing! I know thatâs all I have been saying but I just canât help it!â
Saki half-shouted, being somewhat excited . Hydro 2 and 3 rode through the never-ending, vast, blue ocean, leaving a white trail of foam .
After about an hour of riding fast on the sea, they returned back to Tatsumi bay .
âWelcome back . â
Edgar, who was in charge of the luggage, had come over to the foreshore to welcome them . As for Aal, he was making seaweed salt with Aqua 33 . And Noir had taken a fixed stance as if to protect the luggage .
Jin felt this to be interesting, as their personality could be seen from their roles .
As they drank the cooled pelshika drink, their dried up throats moistened and they felt refreshed, even under the hot sun .
After having the rest of the fruits, the group got back on the automobile and headed back to Jinâs research lab .
