Chapter 217

The underground world of the moon.

In the underground space of the main mining base, it is located in the deep mine which is directly connected to the lunar surface in the center. Suddenly, it is like a waterfall, and the silver liquid metal poured out!

These are the mechanical insects with a weight of about 500 tons, which were separated by Nie Yun. They were dredged and leveled all the way along the mine. At this moment, they finally completed the task and arrived at this underground base.

It means Nie Yun's energy crystal for underground space is about to enter the stage of large-scale exploitation!

After a large number of liquid metal landed, they immediately turned into nearly 10000 small robots, and began to drill into every corner of the core area of the base with small short legs to repair equipment, replace parts and upgrade mining technology.

The original ant robot production workshop was replaced by Nie Yun's small robot growth line, and the spherical mining vehicle manufacturing factory was restored and re opened

After tens of thousands of years of silence, this base has regained the flavor of civilization!

The huge base covers an area of hundreds of kilometers. Even if such a number of robots enter the sea, it is like a bullock entering the sea. It only occupies a few key functional buildings and core areas, and then it is unable to expand. It is expected that there will be a period of time before the resources in this base can be completely digested.

It is much faster to repair and reconstruct the original base than Nie Yun to rebuild the mining capacity of the same scale. If the existing underground mining sub bases are included, the mining system left by aliens will save Nie Yun a lot of time.

A large number of iron and steel materials in the base also provide sufficient phagocytic materials for the mechanical insects. Although the aging is serious, it is like instant noodles soaked for a long time. In addition to the poor taste, Nie Yun says that the mechanical insects are not picky.

But mechanical insects only eat steel, if from this point of view, it is a bit too picky!

"In the future, you have to find a way to change your stink. Your parents used to it when you were a child." Nie Yun expresses dissatisfaction to this characteristic of mechanical insect.

Mechanical insect:.... "

Nie Yun has not yet come to a definite conclusion about why mechanical insects only eat steel. At present, even if the scanning tunneling microscope with the largest magnification is used, it can only observe a single atom by non visual means at most.

However, the volume of nuclear level mechanical insects only accounts for hundreds of billions of atomic volumes. Even at the speed of Nie Yun's scientific and technological development, it is not possible to observe atomic nuclei in a short time.

If we talk about how to shorten this time, Nie Yun says that he can only expect visitors from afar. After all, people are rich without windfall

……

Soon, the first batch of soil containing trace energy crystal particles was collected, and they were directly put into a robot insect liquid pool. After decomposition and phagocytosis of the mechanical insect, a cube energy crystal with a side length of 1 cm was slid out from the lower discharge port 10 minutes later.

From the point of view of cutting, transportation and convenient use, the shape of cube is undoubtedly the most suitable. Nie Yun has planned to use this specification of energy crystal as the standard energy block used by his own machinery.

Although small in size, it contains energy comparable to a small nuclear fusion power station. If installed on a small robot, it can run at full power for thousands of years.

However, Nie Yun will not be extravagant enough to use this precious energy crystal on this kind of small machinery. This kind of high-density energy material can only reflect its real value in high-power weapons and equipment!

For example, just acquired the graviton technology, the core component of the gravity bomb is installed with this kind of energy crystal!

From the consumption point of view, the graviton acquisition device is normal, but the energy consumption of the position shield is astronomical!

Even if Nie Yun has the miniaturization technology of nuclear fusion, if he uses nuclear fusion instead of energy crystal to maintain the operation of this position shield for a long time, then the fuel volume consumed alone will be enough to fill the whole bomb.

From the perspective of interstellar navigation, the quality of nuclear fuel that a space warship can carry is limited. If you use a stand shield in a battle, even if you can greatly improve the protection, your fuel reserves will have to be consumed by 7788 after a battle.

In this case, the endurance combat capability of warships will be greatly limited, and even a large logistics fleet is required to follow in order to conduct long-range operations.

Take a look at the history of modern human science and technology, from coal for steam engines to fuel for internal combustion engines, to electric energy in the era of electrification, and the era of nuclear energy that has not yet fully arrived.

The stage of scientific and technological development of civilization is closely related to the energy and materials used at present! Every industrial revolution, can be said to be a large-scale popularization of new energy!

From the perspective of the structure of gravity bomb, this foreign malicious civilization not only possesses graviton technology, but also develops the use technology of energy crystal.

In addition, both the lunar relic civilization and the eresian civilization, the maker of mechanical insects, have mining and internal records of such things as energy crystals.

The common ground of the three shows that energy crystal is not uncommon in the universe! It is also used by advanced civilization as an advanced energy source of nuclear energy.In Nie Yun's opinion, energy crystal It is the necessary new energy in the interstellar age!

This material can not even be analyzed by mechanical insects, which means that it can hardly be produced by ordinary means. It belongs to non renewable energy. If we look at the oil war, we can see that if its quantity is scarce, it will certainly become a precious resource for everyone to fight for!

Well, to a certain extent, the amount of energy crystal reserves can greatly affect your star wars potential.

Seeing the amazing development potential of this kind of thing, Nie Yun will step up the pace of exploitation and even be ready to leave a nail here even if he loses the war and loses the solar system!

……

Just as the development of multiple lunar bases gradually unfolds, the recovery robots of two alien probes are finally approaching their targets!

Near the two Lagrangian points, two micro thrusters began to jet in the opposite direction and slowly slowed down to approach the wreckage of the two detectors.

As the distance between the two sides gets closer and closer, the two thrusters begin to deform and expand, and they are soon transformed into two thin-film capture nets of about one kilometer.

20 kilometers 10 km 5 km

The distance between the two sides approached rapidly. Finally, the huge net contacted with the wreck. Under the action of inertia, the extremely tough capture net was blocked by the debris, and then directly rebounded and wound up, wrapping several pieces of debris layer by layer.

Soon, the cyborg burrows into the wreckage of the detector. Visible to the naked eye, a silver spot begins to expand on the wreckage
