Airships that are specially designed for passengers are not common in the empire. Although each person's ticket is expensive, compared with the airship's own consumption, no matter which size or level, it is not a good deal. The general method is to mainly carry various commercial goods and take human-to-air behavior assistance.

The front we went to this time was specially selected by Bolang based on Mercelia's position. Not only the convenience of the itinerary, the number of events on the front, but also the number of people sent to the front by hostile countries is also one of the benchmarks to consider. There is some pressure on Cassia now, after all, it is the first time to go there. Even in the military school, he is well-trained and has strong ability to withstand various emergencies. However, the current situation is not much different from the first time he went to Gerun Oasis to perform tasks. At least he can find similar places in his mood.

It is a front line close to the territory of the common country of the distant sea, facing north. When we set out, the sky of Mercelia was already filled with black clouds. Shortly after taking off, the airship could see through the circular windows in the room, a layer of mottled ice had been formed on the bronze iron sheet.

The altitude was raised in a short time after a violent shaking of the airship. When we arrived at the altitude, there was a cloud like a brand new continent below. The sunlight that had not been seen for a long time in winter can be seen through the windows, and the clouds were dyed brightly.

Cassia sat by the window and looked at the borrowed books. From time to time, she looked at the scenery outside that had not changed much for a long time. The sky was still deep blue, and it was really like a quiet lake, as if it could absorb and swallow everything.

It is a deep blue altitude and is one of the taboo areas currently belonging to humans. It is surrounded by powerful airflows without any regularity for many years. The cruiser-level airship can last for only more than a minute, and this is the result of overloading the steam furnace and other numerical numerical overload. As time stays for a long time, when the various stresses gathered on the airship reach the critical point, they burst out in an instant, and it is not difficult to turn a cruiser-level commercial airship with a length of more than 400 meters into fragments in the sky.

Cassia knows that all of this is obtained from the book. It is an experiment by scientists, various levels of airship tests, and over-control seems to be relying on some trained death row prisoners. Due to the special climate in the deep blue sky, radio signals will be greatly disturbed. Except for its own internal lines, external signals are no longer able to accept them.

In the end, without exception, the book did not include military use in the calculation range. The final introduction to military airships was just a sentence that could barely sail in the low-level deep blue field, that's all.

What is the difference between commercial and military use? Cassia has not yet formed a specific concept in his head. It may be because he has never really seen a military airship so far. When he returned to Manoma from Oria, he had a modified airship used by Weberi to transport arms. Although in terms of appearance, all the airships in the Empire have an unavoidable over-bloated figure and the installation location of the lift device is mostly the same, but on the airship in Weberi, you can still see some of the steel plates that were later welded. It seems to be the position of the dismantled gun barrel, or the launching device of the aircraft as the most common weapon of the airship - the bomb. The number is very large. For an airship, it is definitely a completely disproportionate design, covering its entire body. A volley, the firepower covered will definitely be visible terrifying.

It only takes three days to sail in the sky. The closer you go north, the closer you are to the distant sea common country, the more obvious the cold climate of the empire is. Although there is no phenomenon of a surge of more than ten degrees in temperature, most of the snow clouds that have been gathering in the sky have disappeared here.

Cassia remembered that during three days, this kind of commercial airship occasionally flew low, and you could see a piece of white below. There were many areas with heavy snow, but the more time went by, this phenomenon gradually became less.

When Cassia got off the airship and hurriedly chased the express train schedule, most of the regional weather had been away from the snowy days, and the temperature was as cold as it was, but the sky was always clear, and there was a rare sign of snow. The falling white snowflakes would be a relatively rare thing for people near the common country of the distant seas.

If it weren't for the fact that many mountains of varying heights existed on the junction line between the Empire and the Common Country of the Distant Sea, the hot wind brought here from the central current belt would erode more areas of the Empire.

The next three days of journey were all taken by different high-speed trains. The location of the front line is already very close, and the three-day sailing distance of the airship is not comparable to that of high-speed trains. However, the closer to the front line, many commercial equipment does not want to go to do business. Even though there is a long and specially isolated barren area between the boundaries of life and the front line, only the imperial railway tracks were laid here without cost. On the one hand, for civilian purposes, but more importantly, as the exclusive railway line of the Imperial military, machine accessories and ammunition, etc., most of them are transported by railway lines in peacetime. Just a re-train of the Empire is often enough to last for a long time, as long as the senior officials in the military do not have a particularly big appetite.

The lights on the horizon are no longer visible at night. Here, when the distance between the position and the front line exceeds a value, the population begins to decrease step by step. It is difficult for aggregational large cities to appear here, and the population is completely insufficient to support such construction and consumption.
