Survival in Another World With My Master

Failure is based on success.

If you fail, it is a word that reflects on the cause and leads to ultimate success by modifying the method and shortcomings. I mean, what are you saying? Do you understand?

"Uuuuuuuuuuu"

"Koske, Fight"

"This is it... this is it"

"It's a little cosy."

Recently, I feel like it's not compatible with the vehicle... No, I think this kind of thing might be associated with the development of the vehicle.

In conclusion, it was avoided that the board would tilt heavily by putting a magical instrument of retention on the square of the board. However, it is not advisable to apply a measuring golem eye to the square to keep a constant distance from the ground.

There was nothing wrong with moving around flat as a paved road, but when I moved through the wilderness, it swayed like a ship rubbed in a storm. I am a grokie in five minutes.

Me and Ira continued to improve without fail. Should I reduce the frequency of correction by the golem eye? Should the sensor be positioned in four places, front, rear, left and right, instead of squares? Wouldn't it be better to position the sensor in the middle? You don't need a sensor, do you? It took too long to realize that.

Yes, correction by sensors was not necessary in the first place.

The magic of this retention, no matter how much it moved, was designed to maintain its height according to its magic amount, based on where it was first activated. The magic itself contained a technique that remembered the advanced reference point. There was no need to deliberately install sensors in squares to update the altitude reference point in real time and correct the slope.

In other words, a magical instrument of retention is placed in a square so as to maintain the balance of the object to be floated, and a sensor that serves as the reference point measurement position at the initial startup is placed in the lower middle of the vehicle. Then, it would have been better to use only a mechanism that equalizes and controls the amount of magic flowing to the magical instrument.

It was a fractured crust on the far side.

"I've never used a lot of television... sorry."

"No... I'm glad you succeeded. I was able to reconfirm the magic principle of levitation. But what happens if I use it on a high mountain?

"Now....? I don't know because I've never done it before."

Would it be possible to keep the altitude of the top of the mountain if it moved toward the foot with a retreat on the high mountain...? Theoretically, if the point of reference is the point of the levitation... we'll have to try it. I have a feeling it's not going to work.

"Anyway, I was able to build a carrier that didn't shake and wasn't affected by the ground. You think you can use this as a tool for transporting heavy goods?

"Nh, even kids can carry heavy baggage full of carriages."

In fact, I tried to put heavy loads on this cushion-sized experimental device, but even Isla was able to move the luggage easily. However, as the loading weight increases, it consumes so much magic. Therefore, if magic suddenly expires during the transportation of heavy objects, a major accident may occur. We'll need to put some kind of safety device on.

Next is the propulsion system. This has a plan. I just need Ira's help. "

"Of course I'll help."

"Yeah, thanks. I need the help of the court sorcerer, Ira. Wind magic, isn't it?

"Yeah."

"Some of the magic of the wind is just like blowing the wind."

"Yes, this is the easiest wind magic."

When Ira pointed her fingertips at me, a breeze blew into my face from her fingertips.

"Yeah, that's right. I mean, how does that happen?

Ira leans her neck against my words.

"No, the wind is the air flow, isn't it? I don't think there's air coming from my fingertips, and I think it's probably collecting the air around it and releasing it from my fingertips. Can you keep the wind coming out of your fingertips?

"Nh, okay."

As a result of various experiments, it was found that wind magic still collects magic around it and ejects it from the tips of fingers and canes.

"I know the truth... and I know that I don't know anything."

"Well, it doesn't really matter when it comes to using magic normally, does it? But, fuhm."

It turns out that some wind magic gathers the surrounding air and releases it in a constant direction. Didn't you see the magic? The blade of the invisible wind and the magic of emitting it, the magic of flying a compressed air bomb, I didn't understand... what kind of principle is that? I have no idea.

Anyway, what I tested this time was the magic of releasing wind from the tip of my fingers and cane. This is the magic of collecting air from around you and releasing it in a certain direction. In principle, it is the same as a jet engine. However, there are obvious differences from jet engines.

That's weird, isn't it?

"What's wrong?

"No, the magic of the strong wind and the wind of the momentum that blows me away?

"Nh. I literally blew up the magic of the wind pressure above me."

"Yeah, that hurt... that's not it. Why doesn't Isla blow up when she's using enough magic to blow up one person?

……

Since air is taken in from the surrounding area to form a jet, there should always be a reaction there. Given the law of reaction, it makes no sense if Isla, who is firing the jet, does not blow up. It has also been confirmed that the third law of motion is functioning properly in this world. So, explaining the law of reaction to Isla, explaining that it doesn't make sense for Isla to blow up.

"... because it's magic?

"Don't give up! Don't give up. There! Why are you giving up there?

"I don't care if they say that."

That's what it is, so if you're convinced, it ends there. No, there's still a way to get propulsion. If you sail on the retention board (now named) and use the wind magic to blow the wind there, you'll be finished with a boat running on land. But by uncovering the magical wonders of this wind, we should be able to create a faster and more efficient propulsion system.

"In other words, I think wind magic incorporates a technique that offsets recoil. See, even dragons like Harpy and Grande fly magically in the wind? But it's strange to think of ordinary wind magic common sense, isn't it? That."

"Nh, that's strange. Magic efficiency is obvious... is that so?

"Have you noticed?"

That's what I'm trying to say. This is probably the secret to the way in which species like Harpy and Grande use magic to fly in the sky. They are able to fly for a long time with surprisingly little magic consumption. It is clear that they are involved in the magic of flight, and we know that it is wind magic.

But judging by the common sense of magic, it's strange that they can fly. If you continue to maintain enough power to float your body with wind magic, the magic consumption should be too intense to fly for that long. As far as the dragon goes, it's that giant. No matter how many dragons possess magic that comes out of the human race, can you keep flying? That's the answer.

"... are you okay?

"... that was more powerful than I thought."

After meditating for a while and thinking about something, Isla tells me to shoot an improved strong wind magic, so I put a fluffy straw block in the back and let Isla try a new magic with Isla supported from behind.

As a result, Eira and I splendidly flew backwards and collided with the straw block.

"It's fun to know more and more about new things when I'm with Koske."

"I don't feel bad if you say so, but please be careful. I knew that this time it would probably fly with a reaction, so I had prepared a countermeasure in advance. Don't play any other magic tricks to trigger a big accident.

"Nh, I know. I'm still a long way from finding the truth, but I'm still a former court sorcerer. Besides, she's older than Koske. Don't worry about it."

With straw on her head, Isla sticks her little chest. Well, Isla is a thoughtful person... isn't she? Once in a while, I can't see my surroundings... I'm worried.

"Anyway, now we have a vision of the propulsion system. After that, it's a structure... well, at first it's just a simple cylinder."

There may be a more suitable shape, but for the time being, it would be better in the form of a cylinder.

"Should I activate wind magic in this cylinder, excluding recoil removal?

"Yeah, that's fine. Can you flip the ejection direction?

It may be used as a brake if the ejection direction can be reversed. I wonder what to do about the brake problem. Firstly, physically touching the ground... No, air brakes with air resistance? No, the mechanism, how do you get that much air resistance? First of all, you can normally use grounded brakes.

"Yes, I can adjust the output as well as the magic equipment of the retreat."

"It might be good to be able to adjust the output left and right. I think it can swivel due to the difference in output."

"Nh, okay."

Should I put the rudder on the back as well? It may be better to combine the left and right output differences with the rudder. I could throw a round around the R&D department.

While Isla is making propulsion magic tools, I'm going to build a primitive grounding brake mechanism and a vehicle body to put them on. Even though it was a car body, I changed from a cushion-sized wooden board to a wooden board about the size of a double tatami mat and put on a magical piece of television in a square.

"Done."

Well, let's make a golem core and a maneuvering mechanism for the output adjustment.

I don't intend to make it so complicated when it comes to manoeuvring. The wind magic tool on the left and right of the body with the left and right levers... should I give it a name? The official name should be the wind magic propulsion system. I don't need a thruster.

Allow the output of the left and right thrusters to be adjusted with the left and right levers. The more you knock forward, the more you knock down, the higher the output, and the more you knock back, the more you retreat. When the left and right levers are lowered to the outside, they rise, when they are lowered to the inside, and when they descend, the aircraft is grounded to the ground and braked.

"... I'm a little out of shape"

"Because of the prototype machine, there is no way"

I never aimed for the prototype design to feel like a time machine for a blue cat robot. If you travel at high speeds, you will need wind protection to protect the pilot from wind and flying objects, and the design will be refined. It's just an experimental device.

All right, let's get this commissioned.

Be careful.

Leave it to me.

If you don't die right away, you'll be fine. Looks like you've been surprisingly sturdy since you got here, me.

First, press the activation switch to start supplying magic to each magical object. Then the next step is to knock the left and right levers out and float the aircraft off the ground.

"That's enough for now."

"Nh, I floated properly."

"Let's try moving up and down first."

Push the left and right levers inward and outward to raise and lower the prototype floating moving device. There seems to be no particular problem.

"Okay, no problem. Let's start testing the wind magic propulsion system."

"Nh"

The experiment on its own has already succeeded. In other words, the propulsion was too strong, and No. 1 blew away far away. I decided not to go looking for it because it was troublesome. I flew to the Black Forest, so at least the secrets of the Holy King's kingdom never leaked... yes, I'm sorry it was so rough.

Besides, knock the left and right levers forward. With regard to the adjustment of the output, the output can be changed to four stages depending on the angle at which the lever is knocked down.

"Oh, good, good, good."

"It's working."

Travel the wilderness with the lowest power. The lowest output seems to be as fast as walking. It can also be swiveled by differentiating the output of the left and right thrusters.

"All right, let's speed it up."

"Nh, be careful."

When both levers were knocked down another step forward, it was as fast as a rush. Mu, when you swivel, you slip sideways with inertia, and you need to get used to precise operation.

Increase the altitude of the prototype for high-speed navigation. I'm sorry that I bumped into a rock and suffered from pain.

Wow! Ha-ha! Yikes! "

It was faster than I could have imagined if I had raised the altitude and put it in the best four-speed at once. I think the speed is 50 km/h lightly. The wind on my face is strong, and above all, the dust of the wilderness that blows on my face hurts. The vehicle itself needs windshields, goggles, masks, full-face helmets, and more.

After realizing it, he slowed down and returned to Isla.

"I'll ride next."

"That's good, but you should keep it to three speeds. The wind is pouring on my face, and the dust hits my face and it hurts."

"It's okay. I'll use magic to prevent it."

"Did you get that?!

What happens with the magic of the wind barrier without installing the windshield? Should it be incorporated into the main unit? But I didn't have the magic to prevent it.

Isla's a prototype floating mobility device - it's a long one. Can I use a prototype air bike? Run beyond the wilderness on a prototype airbike. Hmm, Isla drives politely. He didn't seem to be the type of person whose personality changed when he gripped the handle.

Ira, who came back after a while, had a very satisfying look.

"This is a good thing. When this is mass produced, there will be a revolution in travel in this world."

"We have to be careful with traffic accidents... because they're faster than carriages, which could lead to major accidents."

"Indeed. Besides, there is a risk of imitation if the Holy King's people catch him. Because the technology itself is just using things from this world."

"That's right... well, I don't think I can help it when it's widely used."

"Nh, but this..."

"Prototype Airbike"

"Some of the technologies used in prototype airbikes can be used militarily, and prototype airbikes themselves can be easily converted militarily. We have to be careful."

I see.

I wonder if a wind magic propulsion system, or a spear like that, can deliver barista power without a launcher? Of course, given the speed and stability of the flight, the shape will need to be devised.

Combined with explosives such as gunpowder and magic equipment with explosive magic, it seems like a powerful weapon can be produced. I also make anti-tank rocket guns, but when it comes to warhead propulsion, wind magic propulsion systems may be technically and materially cheaper to build with this world's technology.

"Besides, the technique of turning off the wind's magic recoil... could be dangerous if they knew about it."

"Watch out?

"I'm not sure yet. However, we may be able to create new magic."

That's what Isla thought. Magic that wipes out recoil... I don't know how it works, but it certainly doesn't feel like it could be used for anything.
