Airships need a lot of power to take the airship itself and the cargo it carries into the sky. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info It was originally developed by the surface people, so it was also a mechanical engine used in the initial design. Due to various limitations, its output is generally limited to a certain extent, and it is enough to fly on the surface, but if you want to fly to the floating continent...... That's basically impossible.

The Floating Continent is too high, far beyond the power limit of ordinary airships, and there are only two ways to get the airship to reach the Floating Continent:

The first is to build airships with very large power and volume, but very small capacity. As long as the total weight of the engine and the load part is controlled, it can fly to the floating continent - however, this kind of airship is quite uneconomical, very low cost performance, and can generally only accommodate one or two people to and from the floating continent; moreover, the safety of this type of airship is extremely unguaranteed, except for some people who "want to go to the floating continent anyway" who have both money and ideals, no one will fight the idea of such an airship.

The second airship...... It's even less affordable. This kind of airship is through strict control of the weight of materials, with the most advanced and efficient engines, so that the normal size of the airship can also fly to the floating continent - however, the cost of this kind of airship is a dizzying figure, only a few large empires can build - yes, referring to the previous one that ruled the surface of the earth. The hull is made of expensive materials that are particularly stiff and lightweight, and the engines are made of special metals with very limited surface storage, and the price is ......

It's not easy to explain from the front, so let's look at the side: after the war passed, there were dozens of submarines sent to the sea below the floating continent to search for the metal of those engines, and it is said that one or two pieces were found - the evaluation of the surface at that time was that it was too lucky, and it was a lot of money.

Its high price consumed most of the Empire's strength, so much so that there was no way to effectively suppress it in the subsequent surface restoration.

As for now, the engine of the first type has been completely banned from being manufactured, and the engine of the second type ...... First of all, no country on the surface of the earth has the money to make such an airship; second, what is there to do with such an airship?

However, the people of the Floating Continent are still quite generous and benevolent. Airship engines are expensive, but they are much easier to solve with the addition of "magic" - mechanical technical problems can be easily solved by magic, so much so that surface engineers exclaim, "This is not scientific!"

Of course, it's not science in the first place.

The people of the Floating Continent are not stupid, they know that they have to keep a hand in everything, they have taught the surface people how to make a regular magic engine, but they have not taught them how to make a high-power magic engine that can fly on the Floating Continent. The production of all high-power magic engines is carried out in cooperation with both sides, and the core technology of the Floating Continentals is kept absolutely secret; moreover, every engine produced has a numbering and monitoring system, and when it is time to scrap it, it must be destroyed by the Floating Continentals - there is no way to leak secrets.

However, if this technical challenge can be overcome...... The surface people may really sneak up on the floating continent.
