Lately Jin has been thinking about something. That is a stove. In Kaina Village… no, in this world, firewood is typically used for cooking.
「A 《Magic Crystal》 as I thought… no, it’s a 《Magic Stone》 I need」
（It can’t be helped, what’s done is done. Hmm, from my hypothesis, the substance of magic power is a particle made up of neutrons and protons that form a nucleus. It should have a similar position to a 《Radioisotope》）
（That is to say, it has a similar concentration to uranium, however there is no materials or equipment for it）
If it was the laboratory, Jin could make a magic element concentration device, but this was Kaina Village so it couldn’t be helped.
「Onii-chan, can we go play?」
「Ah, yeah, that’s right. Where should we go?」
To the south of the village is the Erume River, a big river that supposedly runs to the capital. However, there are several waterfalls along the way so it wasn’t used for transportation by water, was what he heard from Roland.
So the two changed into their swimwear and headed to the river. Well the swimwear wasn’t much different from underwear though. Incidentally, Hanna didn’t have a problem with only wearing the bottom so Jin didn’t worry about it either.
「Ah! It’s Jin-niichan! Hanna too!」
「It isn’t good to suddenly enter the river. You should splash a little water on your body and slowly enter.」
He warned Hanna and Jin slowly entered the river. The place to swim was a deep area with gentle flow. Well it’s not really that deep, the width is 20 metres and the deep areas are only about 3 metre in depth.
「Yeah… it really does」
「Pua!」
The mischievous Kurt came and squirted some water.
「You can’t catch me~」
「Me too! Me too!」
「Caught you Hanna-chan!」
「The only one left is… Kurt?」
「Alright!」
Kurt was caught near the bottom by Mario who was skilled at swimming. At that time, Kurt was flailing about, and the sand at the bottom rolled up. Seeing that, an idea flashed in Jin’s head.
The children who finished playing got out of the water. Because it was nearly time for lunch, everyone returned home.
「Okay~」
「Fuu…」
（An atom with a lot of neutrons must be heavy, so an atom with a surplus of the substance of magic power should be heavy too. If that’s the case then sifting it should be possible like the gold dust underwater）
Hearing Hanna call out, Jin snapped out of his thoughts. Because he pondered too long in the hot water, he returned to Martha’s house while sweating. Hanna had a refreshed face.
Martha told him.
Jin said in the same usual tone, bitterly smiling.
Now the afternoon, Jin came alone to the Erume River once again. As for Hanna, she was taking a nap.
Muttering that, he entered the water. In his hand was a large bowl.
This technique of picking gold dust is called 『Panning』. Of course Jin didn’t have the experience in doing this, but he has seen it being done on the television. ⚑
「《Analyse》… yep, a fire attribute 《Magic Stone》. It has a higher grade than I thought it would」
「Hmm, maybe there’s some relation with what comes out of the hot spring. But, well, this was unexpectedly fortunate」
For that day, Jin continued to collect the 《Magic Stone》 until dusk when Hanna came to find him.
The next day, Jin secluded himself in the workshop. This time he was using iron-based materials. Handling fire is dangerous so although he felt bad about it, he had Hanna go out to play alone.
Recalling the form of the general cassette stove, Jin transformed the iron into an iron plate. Once again, he thought magic was convenient. Being able to precisely do it to this point was because he was the 《Magi Craft Meister》, however he did not realise that.
Although the prototype is in the form of a cassette stove, he hoped the final form would be a gas range.
The first thing he noticed when making it was the adjustment of the heating. The magic power supplied to the 《Magic Stone》 could be adjusted with a knob he implemented.
Bringing the finished stove, Jin went to where Martha was. Just in time, Martha was beginning to prepare for lunch. She had fetched some firewood to boil the pot.
He asked Martha who stopped her hand holding firewood,
「Well yes… this is a 『stove』, it can boil and stew food without firewood」
「That’s right. Could you try and use it?」
Placing the stove on top of the kitchen table, he put the pot filled with water on the trivet.
Martha then opened her eyes wide,
she said in great joy, and Jin was glad.
But to Martha, this magic tool, the 『stove』 is revolutionary.
After several days of testing the prototype, there were no problems, so he made stoves to go around the village. Jin taught them the method to collect the magic stones for replacing them, and all the homes in the village were very thankful for it.
