Chapter 217

The underground world of the moon.

In the underground space of the main mining base, located in the deep mine leading to the moon in the center, suddenly "bang" like a waterfall, silver liquid metal poured out!

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

This means that... Nie Yun's energy crystal for underground space is about to enter the stage of large-scale mining!

After a large amount of liquid metal landed, it 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 plant was repaired and re opened

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

The huge base covers an area of hundreds of kilometers. Even if such a number of robots enter it, it is like a clay ox into the sea. They occupy only a few key functional buildings and core areas, so they can no longer expand. It is expected that there will be some time before the resources in the base are completely digested.

The repair and transformation based on the original base is much faster than Nie Yun's re establishment of mining capacity of the same scale. If those underground existing mining sub bases are included, the mining system left by aliens will save Nie Yun a lot of time.

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

However, the mechanical insect only eats steel. From this point of view, it is too picky to eat!

"In the future, we have to find a way to change your stink, which was used to by your parents when you were a child!" Nie Yun expressed dissatisfaction with the characteristics of mechanical insects.

Mechanical worm: "

Nie Yun has not yet reached a definite conclusion on why mechanical insects only eat steel. At the current level of microscopic observation, 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, nuclear level mechanical insects account for only a few hundred billion parts of the atomic volume. Even with Nie Yun's scientific and technological development speed, it is not possible to observe the atomic nucleus in a short time.

If we say how to shorten this time, Nie Yun said that we can only look forward to visitors from afar. After all, people are not rich without windfall wealth

……

Soon, the first batch of soil containing trace energy crystal particles was collected. They were directly put into a liquid tank of mechanical insects. After decomposition and phagocytosis by mechanical insects, ten minutes later, a cubic energy crystal with a side length of only 1 cm slipped out of the lower discharge port.

From the perspective 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 for his machinery.

Although the volume is very small, the energy contained in it is comparable to a small nuclear fusion power station. If installed on a small robot, it can operate at full power for thousands of years.

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

For example, just obtained the graviton technology, the core components of the gravity bomb are indeed installed with this energy crystal!

In terms of consumption, the graviton acquisition device is normal, but the energy consumed by the position shield is astronomical!

Even if Nie Yun has nuclear fusion miniaturization technology, if nuclear fusion is used instead of energy crystal to maintain the operation of this position shield for a long time, the fuel volume consumed alone is 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. In case of battle, even if the protective power can be greatly improved by using position shield, your fuel reserve will be consumed after a battle.

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

Look at the development history of modern human science and technology, from the coal of steam engine to the fuel of internal combustion engine, to the electric energy in the era of electrification, and the nuclear energy era that has not yet fully arrived.

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

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

In addition, the lunar relic civilization and the Ares civilization, the maker of mechanical insects, have mining and internal records of energy crystals.

The common ground of the three shows that energy crystal is not rare in the universe! It is also used by higher civilization as an advanced energy of nuclear energy.

In Nie Yun's view, energy crystal... Is the necessary new energy in the interstellar era!

This kind of material can't even analyze the structure of mechanical insects, which means that it can hardly be manufactured by ordinary means. It belongs to non renewable energy. Look at the oil war. If it is rare, it will inevitably become a precious resource that everyone competes for!

To a certain extent, the reserves of energy crystals can greatly affect your interstellar war potential.

It was when Nie Yun saw the amazing development potential of this kind of thing that he stepped up the pace of exploitation and even prepared to leave a nail here even if he lost the solar system in the war!

……

Just as the development of multiple lunar bases was gradually spreading out, the recovery mechanical insects of the two alien probes finally approached the goal!

Near the two Lagrange points, two micro thrusters began to spray in the opposite direction and slowly slowed down to approach the remains of the two detectors.

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

20km... 10km... 5km

The distance between the two sides approached rapidly. Finally, the huge net contacted the debris. Under the action of inertia, the extremely tough capture net rebounded and wound directly after being blocked by the debris, and wrapped all the debris layer by layer.

Soon, the mechanical insect drilled into the wreckage of the detector. Visible to the naked eye, a silver spot began to expand on the wreckage
