In the sci-fi blockbusters of the Old Earth period, there are always many scenes where human beings use ultra-high technology to calmly find wormholes and fly freely in multi-dimensional voids, even if they are far away.

It's a pity that due to the continuous war and some unspeakable factors, in the "future" (3042), none of these super-dreamlike flying methods have been realized - the door of space technology seems to be closed to mankind until now.

In fact, even if human researchers accidentally discover a stable wormhole, no one dares to defy it. After all, there are too many uncertainties in the Void Channel, such as Void Devouring, Void Rays, Void Turbulence, etc., and if you enter it rashly, not only will you not be able to fully deal with these variables, but you may also get lost in the Void. When that time comes, there will be no second fate except death.

Therefore, human beings are still in the same down-to-earth, step-by-step flight mode as before. If anything, it can only be said to have become faster, higher, and stronger.

However, due to the vast territory of the Human Federation and the large area spanning it, it is extremely time-consuming and labor-intensive to simply fly. For example, if you want to go from the location of Huaxia Star in the Northeast Star Domain to the Federation Capital Star in the Southwest Star Field, even if you send the strongest Federation-class warship to fly in a straight line at a speed of light close to 30km/s, it will take as long as a month. It is not known how high the energy consumption will be. But everyone knows that such a theorized full-speed flight does not exist in reality, and there has never been such a thing as a straight course in interstellar flight.

In addition, even if the starship already has a relatively stable energy shield to protect their safety, it is also equipped with various functional areas that can ensure human comfort. To some extent, the starship can basically meet the flight requirements technically, but the human beings in it may not be able to withstand this kind of near-prisoner interstellar flight for a long time.

For this reason, human beings have invented various types of accelerators, such as curved surfaces, slingshots, springs, swings, and projectiles, according to various principles that can accelerate objects. In the process of interstellar flight, human interstellar spaceships or warships can be fixed in the planet's airport along the way according to their own needs, using accelerators of different speeds, without stopping, the ship can be accelerated, and at the same time, it can also complete the recharge, which greatly improves the flight efficiency.

For example, on the Federation map, the distance between Huaxia and Liberty Nine is not too far, but that refers to a straight-line distance, not the actual sailing distance. The shipping route between the two would have to stop at 20 airports for acceleration, which would take at least 10 days.

Speaking of this accelerator, we have to mention the ships used for interstellar flight.

According to the Federal Interstellar Flight Regulations, ships of different classes can only use accelerators of the corresponding level, and no overstepping is allowed.

Unlike the planetary ground civil spacecraft system, which is only allowed to fly on the surface of the planet, and can only use conventional energy sources, such as solar energy, the ships used in interstellar flights generally use microscopic particle energy, such as nuclear energy. Of course, the exception is the Dreamy Custom Ship, which can also fly interstellar if you can change the power engine and energy system.

With all the above restrictions, the manufacture or use of these interstellar ships requires them to apply for various licenses in accordance with laws and regulations in order to pass unimpeded. And those unlicensed and unlicensed black ships, once discovered by official patrol teams, may face frantic pursuit and even hunting.

As for the classification of those interstellar ships, in fact, there is still a big difference between them and civilian ships on the ground. Generally speaking, in order to distinguish the difference between ground-based vehicles and interstellar vehicles, they are called a little differently. For example, the term spaceship is generally only applied to ground vehicles, while interstellar vehicles correspond to interstellar spaceships and interstellar warships - spaceships are civilian and warships are used in the military.

In a sense, civilian starships are starships that have been weakened in various levels in terms of power engines, energy systems (energy types, energy capacity, etc.), hull materials and processes. There is still an essential difference between the two.

Functionally, starships are only used for passenger and cargo transport, while starships are only used for warfare. The former level can refer to the ground spacecraft, and the latter level has five levels - from low to high, which are city level, free star, regional level, star field level, and federal level.

City-level, as the name suggests, is named after the city, such as the Eight Tigers, Huaxia City, etc.; Freedom Star, named after the planet, such as Huaxia Asterisk, Capital Asterisk, Nine Free Star, etc.; At the regional level, it is mainly named after the head of one party's forces, such as the Miaozhu ship, the Pope's ship, etc.; Star field level, most of which are divided into federal administrative regions, such as east, south, west, north, etc.; Federal-level, more special, mostly in the name of legends......

It is worth mentioning that above the Federation class battleship, there is also an ultimate weapon, which combines the strongest attack power and the strongest defense power.

That's Mobile Fortress, aka Battlestar.

This is the ultimate weapon controlled by the federal gendarmerie "Protector of the Law" from the very beginning of the establishment of the Human Federation, mainly to defend the dignity of the Constitution and human freedom. They are above the Federal President and in the hands of the Federal Parliament, but they are only at the behest of the Federal Constitution of Mankind. It can be said that because these Battlestars have been above board for a long time, but they are cruising in all corners of the Federation out of nowhere, to a certain extent, they have deterred and discouraged the ambitions of many conspirators, so that it is difficult for the Federation to rise to gunpowder now.

With such a hierarchy, the construction standards of civilian interstellar spaceships used in interstellar flights will generally stop at the Liberty star.

In today's world, since the Sea of Death incident, with the status of the Tianxing family, its travel has changed from low-key and secretive, to high-profile dressing, and the choice is basically a Liberty-star-class starliner. In order to encounter those shady means again, causing fatal injuries.

However, this time the situation is different. Because the potential enemy is the Heavenly Spirit Temple, the trouble is huge, and it is also a private matter to go to the ninth free star, so naturally the more low-key the better.

Therefore, they went to Liberty Star 9, and naturally they took a city-level starliner.

"What are you two doing here whispering? You can't have any bad thoughts, do you? Don't you think this matter is big enough......"

Tianxingkang found Tianxing Rongruo and the copper coin in a corner of the first floor of the square hall array ring, and when he saw that the two were still chatting leisurely, he was so angry that he couldn't help but accuse a few words when he opened his mouth, and then saw that the time was urgent, and he had to rush to go.

"These days, until the problem is completely solved, give me a little peace...... Well, we have to hurry to the airport of Huaxia City and board the starliner at half past one in the afternoon......"
