Compared to on the ground, space operations are silent operations, there is no sound, only light. However, as the saying goes, "silence is better than sound at this time", because silence leaves a space for imagination.

There are not many spacesuits, only a group of ten people, even if Zhang Jingyuan and Gao Chengyang are already great masters in the Jindan period, they don't dare to test their endurance in space. As long as you need oxygen one day, don't try to walk unprotected in space.

Under the guidance of scientists, standing on the side edge of the space station, Zhang Jingyuan quietly looked at the behemoth in front of him; The strong sunlight gilded the sunny side of the steel monster with a brilliant color. At a distance of 500 meters, the distant shady position is hidden in the dark space. And the photovoltaic cells in a radius of ten kilometers, only a wide blue line can be seen in this position, like a sharp blade, across space

A steel plate 100 meters long and about 6 meters wide trembled and fell on the steel shelf, relying on the automatic welding robot arm adsorbed on the space base to crawl automatically and accurately, and accurately weld the steel plate to the skeleton. Its accuracy can ensure that the weld of ten kilometers long can not find the disadvantage of the size of a needle's eye.

Such steel plates are basically welded and polished on the ground before being placed in the cabin of the Space Shuttle Rise and sent to space. Such a heavy steel plate, with a thickness of more than 3 centimeters, is about 150 tons per piece, and in order to ensure the safety of the space base, the outside should be covered with 3 layers of such steel plates, which add up to 10 centimeters thick.

In the construction of space, after comprehensive consideration, the master company abandoned the titanium alloy that was thought to be born for aerospace, and chose bulky steel instead. The reason is very simple: the mass production technology is mature, the process is stable, and the maintenance is convenient in the later stage; The most important thing is that under the existing conditions, steel is still among the best metals of the same thickness, and if you count the cost, etc., it deserves to be the first.

A welding robotic arm landed in front of Zhang Jingyuan, a group of three welding guns, easily melted the steel, and the special welding rod was exactly the same as the material of the steel plate, achieving a perfect fusion. The welding robot arm automatically retreated, leaving a red weld in front of it, and then quickly cooled down in space; Throughout the work, there was firelight, but there was almost no debris. This is one of the hardest parts of space operations. Compared to the Earth's land, detritus settles automatically; And in space, the slightest debris can penetrate the human body like a bullet.

And even so, the protective steel plate specially installed on the outermost part of the spacesuit on the staff has been pitted. There are very few operating environments that can be compared to space; Beautiful and great, but with the danger of life.

Feet gently and slowly landed on a steel plate that had just been welded, and a loud noise came from under his feet, which was the sound of the steel plate impacting, and not far away, a steel plate had just fallen to the skeleton and began to weld.

And then there's the roar of the engine's work.

In order to adjust the orbit of this behemoth, a full 10 K01 engines were placed in different positions, and thousands of small ion engines provided by the state were used to correct the orbit in space.

Every time the steel plate and steel column land, the orbit of the space base will be disturbed, and one or two points may not be visible; But if you don't fix it, at most a day, this monster will crash.

And to adjust such a behemoth, just the existing steel bracket weighs more than 20,000 tons, and to adjust such a monster, even the engine of the K01 model must be started with all its might. Then, it needs to be turned off within 0.3 seconds, otherwise the monster will rush out of orbit.

Standing on such a man-made object, you will find that people are so small, but it can also be seen that the space base that the master company has set up to awaken and build is not idle, it is not a narrow space capsule in the traditional sense, but a real space base. This will be able to meet the living needs of more than 10,000 people. It will also be the first real space migration base for mankind.

Zhang Jingyuan and others returned, and the rest of the master company executives came down to inspect one by one. In the age of space, you must have a view of the sky! And the shortest way, and the most difficult way, is to take a look at space!

To put it simply, it's a trip; However, it is difficult to say, and it is easy to understand, the space shuttle, not the bicycle! Then, all the senior management of the master company stayed in space for 48 hours, including watching the moon, watching the earth, watching the third unlucky comet, looking at the interval of a solar magnetic storm, rushing into space, and enjoying space surfing.

The process of the space shuttle returning to the ground is wonderful, even Zhou Feixuan, a master who is close to the Jindan period of the catastrophe, also let out a terrifying scream. Orange-red flames enveloped the shuttle; No, it's not a flame, it's a stream of air that heats up after intense friction, but just what it looks like on the outside. At this time, the space shuttle had a speed of up to 7 kilometers per second, which was the most vulnerable moment for the space shuttle, and once it was attacked, it had almost no ability to resist.

Zhang Jingyuan is very self-aware, and it is estimated that many countries want to destroy the master company, not to mention anything else, the United States and Russia, if there is an opportunity, these two countries will definitely not be soft. Therefore, Zhang Jingyuan did not dare to test with his own life, and he was prepared for the best and the worst. In fact, since the take-off, the satellites in space have not stopped working, and the 50 space shuttles have really made all countries pinch a cold sweat; The master company is afraid of a sneak attack, but these countries are also afraid that the master company will suddenly have a convulsion and destroy all the satellites in space! Although it may be low, it is not possible that someone will have a convulsion......

Therefore, the master company is a batch of ten planes, slowly rushing into the atmosphere, until one wave stabilizes and can move flexibly in the atmosphere, and the second wave begins to sprint.

Because this time they are all at the top of the master company, none of them have cultivated below the 6th floor during the training period, so the pilots are relieved to brake, and the acceleration has climbed to more than ten times in an instant, and in just about half a minute, it has been leveled, and in the atmosphere, flexible flight.

When the 50 planes of the master company landed collectively, the huge scene made all the representatives of various countries who came spontaneously lose their voices.

Through the porthole, Zhang Jingyuan smiled, this is his purpose! Yes, Zhang Jingyuan is not just for visiting space, but more importantly: Liwei!

In the space age, values in the traditional sense have completely collapsed, and in the trillions of space transactions at every turn, even the major European and American powers, with all their national efforts, feel at a loss for the development of space.

The Swiss side of the deal, and not secret, these people already know. Switzerland, a small country with an area of 40,000 square kilometres, has to pay such a price.

So, what does a country like the United States pay for?
