However, it is a bit regrettable that although humans have detected that these crystals contain huge energy, they cannot extract the energy in them for the time being, because according to the detection, the energy inside these energy crystals is very stable. If you want to destroy the structure inside the crystal, there is really no good way to destroy these crystals except to directly destroy these crystals.

In addition, these crystals have very strong hardness and willfulness. In terms of hardness alone, they are about fifty times that of diamonds. It can be said that even if these crystals are not used as energy sources, their uses are very considerable in terms of industrial cutting and other aspects.

After all, the technological development of human civilization is getting stronger and stronger, and the performance of its materials is getting stronger and stronger. However, the development of material technology has also brought new problems, that is, the welding and cutting of these new materials is a big problem. It is easy to say in the welding of these metal materials. After all, with the current technology of human civilization, even if the temperature reaches thousands or even tens of thousands of degrees, it is possible to achieve it.

But in terms of cutting, it is different. Take the keel and shell inside the Dijiang spacecraft as an example. Nowadays, human civilization can only use casting methods to directly cast parts, and then use other methods to slowly cut these materials. It takes a day, one night, or even longer to cut an alloy material that is only one meter and is less than 30 mm thick.

Of course, compared to cutting, drilling holes is actually even more troublesome. However, there is no way to do this. After all, drilling holes must be carried out in many places on warships.

Not to mention using machine tools to process these materials, it will be even more troublesome. After all, the hard-mouthed materials of human civilization are only less than 10% harder than those of warship keels and other materials. The knives and drills made of these materials are very brittle, and even if they accidentally fall to the ground, they may be crushed to pieces.

Therefore, you must be careful when processing. If you are not careful, the speed of the machine tool or drilling machine is too fast, then the tool may be directly broken.

It can be said that the most important reason why the Dijiang spacecraft designed by Tiangong Technology is so slow is that it is also the reason. If the problem in this regard can be solved, then the manufacturing speed of the Dijiang-class space fighter of Wang Bin and Tiangong Technology can at least reach one ship per month, and as time goes by, the lunar base is becoming increasingly perfect, and the speed can be increased.

Therefore, even if human civilization still does not understand these crystals, it is impossible to derive the energy inside the crystal. Its importance to human civilization is also very important.

Of course, what made Wang Bin and others most happy was that at this time, the reserves of these crystals on Ceres reached nearly 200 million tons. Such storage was enough for human civilization and had been used for a long time.

However, at this time they did not know that even if the storage capacity of minerals such as Ceres, which reached nearly 200 million tons, it would be far from meeting the needs of human civilization. Even if human civilization discovered more such ores in the Kuiper Belt in the future, it would not be able to meet the needs of human civilization.

For this reason, human civilization had to go out of the solar system, go to a wider universe, and compete with other civilizations in the Milky Way for resources.

With the attention of the command center, more than 20 super-large aerospace planes have been transformed in less than ten days, and all have been loaded with materials to prepare for construction. At the same time, there are natural professionals who go to Ceres with these materials. This time, there are more than 300 people who follow the materials.

Of course, in addition to materials and personnel, there are also various professional engineering construction machinery and equipment for vacuum environments.

Since human civilization began to build a large number of projects on Mars and the moon at this time, engineering machinery has gradually improved. Even among the people, there have been many cosmic engineering construction machinery companies. Many of the equipment produced by these companies are very professional and safe, and even the process machinery produced by some companies are unique.

Of course, compared with the private sector, the engineering equipment produced by official enterprises is better.

Although the number of super-large aerospace planes to Ceres this time is as high as twenty, and each super-large aerospace plane carries as many as thousands of tons of supplies, compared with the construction of Ceres Fortress, this little bit of supplies is simply a drop in the bucket and is far from enough.

Fortunately, the transformation of super-large aerospace planes is still underway, and their speed is not slow. On average, two or three aerospace planes are being renovated every day, and the existing super-large aerospace planes are being quickly transformed.

In addition, in terms of the production of super-large aerospace planes, Tiangong Technology is now driving full power, producing at an average rate of one to two a day. It is conceivable that in no time, the number of cosmic long-range transport aircraft owned by human civilization can exceed one hundred. At that time, as long as these aerospace planes are transported continuously, they can basically meet the needs of Ceres.

Of course, if other asteroids in the asteroid belt also start to build fortresses by then, these aerospace planes will definitely not be enough, but at the current speed, it will not take long to meet the construction of these fortresses.

Just when the Dijiang spacecraft was inspecting Ceres, the first space warship of the Earth civilization near the Earth's forbidden orbit Ziwei space station, the Xuanming space warship, was completed after several months of outfitting, which made the human civilization's own foundation suddenly become much more complete.

After all, although the Xuanming space warship is the first space warship of the entire human civilization, no matter what, according to the previous level classification of space warships by the Blue Star civilization, the Xuanming space warship is already relatively the main ships of other civilizations in the Milky Way. In terms of performance of the spacecraft, except for the lack of protective covers, other performances are no less than the main ships of major civilizations in the Milky Way.

According to the previous statement of the Blue Star Civilization ‘Sea’, such a battleship can easily kill a fleet composed of more than ten planetary warships.
