Survival in Another World With My Master

I gathered many insights into magic, magic, and miracles - special abilities that could not be thought of in the original world.

First of all, it was clear that all abilities, whether miraculous or magical, used magic in some way. I almost certainly think that the main application is the energy source when causing various events, but I think the conversion efficiency is very good.

For example, it's Isla's lightning spell, but it seems to have almost the same power as a naturally occurring lightning bolt. Surely the lightning voltage and current is at least about 100 million volts, tens of thousands of amperes. Needless to say, the energy generated instantaneously by one human being is an out-of-standard number.

Huh? It's amazing, isn't it? That's right... the 5.56 mm NATO ammunition commonly used for assault rifles has about 1300 joules, the 7.62 x 39 mm ammunition has about 1500 joules, and the 12.7 mm ammunition used for antimaterial rifles has about 18,000 joules of energy.

In contrast, the energy of a single shot of lightning is roughly 1,000 megajoules. It's not Jules. It's Mega Jules. That's a billion joules. Well, it may not make much sense to directly compare the energy on a bullet with the energy of the lightning itself, but still, the energy difference is about 5500 times that of a 12.7 mm bullet.

Isla can treat such energy with such a small body. Moreover, if the magic is in a state of total pleasure, it seems that about ten shots can be released in a row. I think you can see how magic and magic can't be considered in common sense in that world.

"So I decided to stop thinking about clarifying the magic itself and how energy conversion efficiency works. I want to leave it to the scholars or magicians of the future."

"Nh"

"What are you running from?

"I'm not running away. This is a turnaround."

Things seem to say. It would be a very reasonable decision not to think because it seems like I have no choice in thinking about it. It's an unexpectedly self-portraying level decision.

"So, here it is. I want to go back to basics."

"What do you mean?"

"I mean, it is. I don't have any urgent issues, so I'm going to run to my hobby."

"I've begun to pronounce myself a sabotage."

"Oops, don't get me wrong. I don't eat, sleep, or get soaked. They make tools that might be useful to people. In some cases, mass production may be officially decided and disseminated to the public to dramatically improve people's lives."

Put your hand out on the freezer with Jito's eyes facing away, raise your index finger and shake it to the left and right.

"Nh, Koske's idea of an airboard has actually been adopted by the Liberation Army, and now we are also running a low-cost version of the test. It should be available to the public soon."

Isla says the inexpensive version of the airboard is a new carriage with flotation equipment installed instead of conventional wheels. Maintenance costs quite a bit, but it seems to have gained a reputation for being able to carry more luggage more quickly than ever before. As there is no friction between the wheels and axles, it seems that the travel distance per day has nearly doubled due to less burden on the horse.

With regard to the flotation devices used in airboards, they are made within the scope of conventional techniques, such as the magic of levitation, so there seems to be no need to conceal them. However, it can be said that the propulsion system created by intentionally eliminating the recoil removal technique from the blower magic is quite a breakthrough technology, and since new technology has been introduced for the operation system, there is no intention to sell airboards with full specifications so far.

"Even if you say you make tools that help people, is it that easy to come up with?

"That's it. I'm thinking of using magic to recreate the convenience of my world."

I see.

"Hmm... for example?

"I don't know... maybe a fridge or something."

When refrigerators become popular, they can make fresh food more sustainable. Will the general family be valued in restaurants and restaurants, of course?

"Beautiful?

"What's it like?

Um...

Explain what a refrigerator looks like to Isla and Ifrita.

"I see. Sure, in summer, raw things get damaged easily. I know that food is less likely to rot in dark, cool places, such as basements, than in warm places."

"There's an ice-cold room in the castle that keeps ingredients frozen, but there's nothing like that in a commoner's house."

"There's a freezer!?

"It's called an ice-cold room, not a beauty room. It's as cold as midwinter in summer when you come in. But the ice cold room in the castle used such a large spiritual stone to sign a contract with the ice spirits."

Ifrita showed the size with her hands. It's a little bigger than a softball... about the size of a baby's head. Spirit stones are sure to be made by Elves processing gems. That certainly seems expensive.

"Of course I don't use anything that works. Isla, of course there's magic in making ice, right?

"Nh, there is. Ice Bullet"

So Isla put out her hand, and in an instant she made a chunk of sharp ice on her hand, and showed it to her.

"The magic is like making ice, sharply molding it, and flying it to the point."

"It's kind of like that."

"Is there any magic to freeze the water there?

"... I've never heard of it."

"Nh... maybe it's not in the existing magic. But I think it can be made by applying the magic of ice bullets or the magic of snowstorms. I think spiritual magic makes it easy."

Don't you have one? Specializing in attack magic? The magic of this world.

"It's okay to make magical ice with ice bullets just by pulling out the magic ceremony and turning it into a magic instrument. I'm thinking about an ice fridge."

I'll give you an overview of the ice refrigerator I'm trying to make on paper. An ice refrigerator is a large box with two levels of upper and lower insulation. Place a metal box with good thermal conduction efficiency in the upper stage and put ice in it to cool the air in the lower stage. And by keeping that cool air trapped in a box made of highly insulating material, we keep the ingredients inside cool.

Prior to the spread of electric refrigerators, they were widely used around the world. I heard that there were a lot of ice shops that supplied each household with ice at that time.

"In my world, I was able to freeze and chill food directly in every home without using ice and electricity. It's hard to stably supply a lot of magic in this world, isn't it?

"Nh, it's hard without a blow-out hole in the ground vein."

"I see. But then you don't have to put ice magic on each of those fridges? Just like in your world, it's more profitable to sell only boxes, make magic tools to make ice, and run an ice shop in the country."

"... oh"

"Sure."

Unexpecting to point out the Ifrita, I hit him. That might be the case. There was a consciousness of creating a new tool using magic, but considering the refrigerator as a commodity, it seems more profitable for the Kingdom of Merinard to create a new interest and employment as an ice shop.

"You guys are technicians somehow...."

Ifrita sighed and shook her neck sideways.

"I can't say anything if you say so... but I think it's more convenient to use magic tools to make ice."

"If you put magic equipment on each one, it will be expensive. Even if it's convenient, can't ordinary people buy it?

"Kh... that's for sure."

"I'm not good at money accounts either, so I think it would be better to talk to Merti who is good at that kind of thing. I think it would be a good idea to clarify how much it would cost to make these three prototypes, starting with just the box of ice, the one with the magic equipment to make ice, and the magic equipment for ice makers to make ice. Then you can take it with you."

"Yes"

"Okay."

Me and Ira nodded honestly. You can't just make things that are efficient and convenient... is that what scales fall out of your eyes?

"What are you looking at?"

"No, I was just suddenly reflecting that I was looking at people with preconceptions."

"I see. Can you tell me exactly what you thought of me?"

It took me a while to forgive the ifrita that smiled while floating blue muscles in my temples, but with regard to the enclosure, I was able to use my craft ability to make some prototypes early. Let's go talk to Merti as soon as Isla makes ice magic equipment.
