Super Mothership

Underworld of the Moon.

In the underground space of the main mining base, in the deep mine in the center that leads directly to the moon, it suddenly "popped" like a waterfall, and silver liquid metal poured out!

These are the 500-ton mechanical worms that Nie Yun separated out. They dredged and leveled the mine along the way. At this moment, they finally completed the task and arrived at this underground base.

This means... Nie Yun's energy crystals in the underground space are about to enter the stage of large-scale mining!

A large amount of liquid metal immediately turned into nearly 10,000 small robots after landing, and began to drill into every corner of the core area of ​​​​the base with short legs, repair equipment, replace parts, and upgrade mining technology.

The original ant robot production workshop was replaced with Nie Yun's small robot growth line, and the spherical mining vehicle manufacturing plant was restored and rebuilt...

After being silent for tens of thousands of years, this base has regained the breath of civilization!

The huge base covers an area of ​​hundreds of kilometers. Even if such a large number of robots enter it, it is like a mud cow entering the sea. It only occupies a few key functional buildings and core areas, and it is unable to expand any more. It is far from completely digesting the resources in this base. Think it will be a while.

Repairing and transforming on the basis of the original base is much faster than Nie Yun's re-establishment of mining capacity of the same scale. If the existing underground mining sub-bases are counted, the mining system left by the aliens will save Nie Yun. Cloud quite a lot of time.

The large amount of steel materials inside the base also provided sufficient phagocytosis materials for the mechanical worms. Although the aging is a bit serious, it is like instant noodles that have been soaked for a long time. Except for the poor taste, Nie Yun said that the mechanical worms are not picky eaters.

However, the mechanical worm only eats steel. If you look at it from this point of view, then it is a bit too picky!

"In the future, you have to find a way to correct this stinky problem of yours. Your parents were used to it when you were young!" Nie Yun expressed dissatisfaction with this feature of the mechanical bug.

Mechanical bug: "..."

As for why the mechanical insects only eat steel, Nie Yun has not yet come to a definite conclusion. 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 individual by non-visual means at most. atom.

However, the nuclear-level mechanical worms have a diameter between 10-15m and 10-14m, and their volume only accounts for one hundred billionth of the atomic volume. Even at the speed of Nie Yun's technological development, it is not a short time to observe the nucleus. can do.

If there is a way to shorten this time, Nie Yun said that he can only look forward to visitors from afar. After all, no one is rich without windfall...

...

Soon, the first batch of soil containing trace energy crystal particles was collected, and they were directly put into a liquid pool of mechanical insects. After being decomposed and swallowed by the mechanical insects, ten minutes later, a side slipped out from the discharge port below. A cube energy crystal with a length of only 1 cm.

From the point of view of cutting, transportation and ease of use, the shape of the 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 machinery.

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

However, Nie Yun would not be so extravagant to use this precious energy crystal on such a small machine. This high-density energy substance can only show its true value on high-power weapons and equipment!

For example, the core component of the gravitational bomb was installed with this kind of energy crystal just after acquiring the graviton technology!

In terms of consumption, the graviton collection device is still normal, but the energy consumed by the position shield is simply an astronomical figure!

Even if Nie Yun has the nuclear fusion miniaturization technology, if nuclear fusion is used instead of energy crystals to maintain the operation of this position shield for a long time, then the fuel volume consumed alone is enough to fill the entire bomb.

From the point of view of interstellar navigation, the quality of nuclear fuel that a space warship can carry is limited. If you encounter a battle, even if you use a position shield, the protection can be greatly improved, but after a battle, your fuel reserves will be reduced. You have to consume seventy-seven-eighty-eight.

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 combat.

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

The technological development stage of civilization has a close relationship with the energy material currently utilized! Every industrial revolution can be said to be a large-scale popularization of new energy!

From the perspective of the structure of the gravitational bomb, this alien malicious civilization not only possesses graviton technology, but also developed the technology to use energy crystals.

In addition, the lunar relic civilization and the maker of the mechanical bug, the Ayres civilization, both have mining and internal records of energy crystals.

This commonality of the three shows that things like energy crystals are not uncommon in the universe! And it is also used by higher civilizations as an advanced energy source for nuclear energy.

In Nie Yun's view, energy crystals... are the new energy necessary for the interstellar era!

This kind of substance can't even analyze the structure of mechanical insects, which means that it can hardly be produced by ordinary means. It belongs to non-renewable energy. If you look at the oil war, you will know that if it is scarce, it will inevitably become a kind of human being. People scramble to cherish resources!

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

Nie Yun just saw the amazing development potential of this kind of thing, so he will step up the pace of mining, and even prepare to leave a nail here even if the war loses and loses the solar system!

...

Just as the development of multiple bases on the moon was gradually spreading, the recovery mechanical bugs of the two alien probes finally approached their goal!

Near the two Lagrangian points, the two micro-propellers began to jet in opposite directions and slowly slowed down to approach the wreckage of the two probes.

As the two sides got closer and closer, the two thrusters began to deform and expand, and soon transformed into two film-like capture nets about one kilometer long.

20km…10km…5km…

The distance between the two sides approached rapidly. In the end, the giant net came into contact with the wreckage. Under the action of inertia, the extremely tough catching net rebounded and wound up after being blocked by the wreckage, wrapping all the pieces of wreckage layer by layer.

Soon, the mechanical worm drilled into the wreckage of the probe, and visible to the naked eye, a silver spot began to expand on the wreckage...
