Under the moon!
Nie Yun looked around for a week and was stunned.
It is different from his imagination of an empty space or the construction of an alien base full of science fiction.
This is a huge and desolate underground world, but it is not completely natural, but there are a large number of man-made pillar structures!
Looking around, the height of this underground space is about tens of kilometers, and every hundreds of kilometers, there is a black support column like an Optimus giant standing there, as if countless Optimus giant hands have opened up this world!
Although stalactite columns in natural karst caves can form similar landscapes, it can be judged that they are not naturally formed, but man-made supporting structures only by looking at the color completely different from the surrounding soil and the uniformity of distribution!
"Here... What's going on?" Nie Yun was completely shocked by the scene in front of him.
Just think, if not only here, but also the whole moon is in this situation, how much should this project be?
Can it be completed after all mankind has worked for 5000 years?
Nie Yun carefully observed the surrounding environment. It was obvious that the ground had been preliminarily leveled, and there were some slight traces of suspected large-scale construction machinery moving on it.
"Step!" Nie Yun stepped heavily under his feet, and his body ran up hundreds of meters like a flea, and then slowly flew to the nearest black stone pillar several kilometers away.
It is close to the lunar core, and the gravity has been greatly weakened. It is almost one tenth of the gravity of the lunar surface and about one sixtieth of the gravity of the earth. Nie Yun, 200 kg, is as light as a swallow.
The scene of flying across the sky appears in this underground world. At least if Nie Yun makes a film, he can not hang Weiya.
With the strong power of this body, Nie Yun realized a high-speed movement of 240 kilometers per hour by No. 11 road alone. After only two or three jumps, he came to the target.
From a nearby point of view, the diameter of this black stone column is about 500 meters, just like a majestic mountain!
Nie Yun looked closer and found that the stone pillar was not black all over, but had a fine black grid. The general lines covered the original gray stone pillar, and even extended to the interior of the stone pillar, which was a little similar to... Parthenocissus?
"It's really weird! It seems to be a reinforcement means?" Nie Yun guessed.
He tried to grab a handful of black material and pulled it. He almost tried his best to break it. For the strength of this body, this degree of tenacity is quite amazing!
Nie Yun then directly put his palm on the black material, then swallowed it, closed his eyes and felt it. Nie Yun opened his eyes in surprise.
This black material contains a lot of metal components, and its microstructure is similar to... Plant fiber?!
"Is this really a plant?" Nie Yun was stunned.
Nie Yun walked around stone pillar, but found no other abnormalities.
It takes so much time to build such an underground space, but there are no buildings here. It's not like expanding the base or living space?
Aliens don't drive Lanxiang. Is this their excavator training base?
"It seems that there is some space... Eh? Wait! Where does the light come from here?" Nie Yun finally found another abnormality.
The underground space is extremely empty, but there is no bright light source, but it is as bright as day. Nie Yun observed carefully and finally found that the light source is... The gray soil around!
He leaned over and grabbed a rock to look at it carefully. Then he frowned. He pinched it hard in his hand, and the rock was directly pinched into powder by him.
Then he spread out his palm and looked at the powdery material on it. The pupils in his eyes contracted for a while, adjusted the focal length and turned into a pair of "microscopic eyes". Finally, he saw that there were small red crystal particles that could not be observed by the naked eye, and the light source was emitted from them.
"What's this?" the curious Nie Yun simply lost another phagocytosis identification technique.
The powder on the palm was quickly broken down, but Nie Yun was stunned to find that the identification technique... Failed!
In addition to the soil rich in metal materials, the red crystalline material was indeed decomposed, but to his surprise, the mechanical insect did not obtain the microstructure model of this red crystal!
The invincible "phagocytosis * identification" failed! This is a situation Nie Yun has never met.
In his induction, the red crystal was apparently broken down by mechanical insects, but the decomposition was not complete. Soon he found the reason for this situation.
We know that the scale of the mechanical insect itself is the nuclear level, and so is its decomposition scale. The basic microstructure of this red crystal... Is even smaller than the nuclear level!
"Is there a natural crystal with this structure?" Nie Yun was surprised.
Although the mechanical insect can not completely decompose the crystal, it can be kneaded and constructed on the micro scale.
Because the content of this red crystal is too rare, Nie Yun then swallowed some soil, which slowly grew a small red particle the size of sesame in the palm of his hand. Nie Yun carefully placed it on the belly of his index finger and observed it.
The surface is very smooth, like red crystal, and emits soft light at all times.
Nie Yun looked at the tiny crystal and was suddenly stunned. He felt inexplicably that he seemed to know this thing!
"This is... Energy crystal!" Nie Yun exclaimed.
When Nie Yungang just got the mechanical insect, the mechanical insect once conveyed a message about absorbable energy.
The energy that mechanical insects can use includes solar energy, electric energy, chemical energy, thermal energy, nuclear energy, energy crystal (focus), antimatter annihilation energy
After nuclear power, it is the energy crystal!
Absorbing energy is the instinct of mechanical insects, so Nie Yun can also sense that the crystal in his hand... Can be eaten!
"Absorb!" he thought.
"Hiss ~" Nie Yun trembled, and a huge amount of energy poured into the body. Nie Yun shouted to stop!
"Hoo! It almost burst, which is too exaggerated!" Nie Yun, who was flashing a light of leakage, looked at the red crystal that seemed to be dimmed in his hand and felt a lingering fear.
Just a sesame sized grain, the energy output just now is even more exaggerated than the instantaneous output power of the main energy core of the sea wolf!
Nie Yun knew that he had found a treasure!
Needless to say, this kind of energy crystal, which even mechanical insects are listed as absorbable energy, but people on earth have never heard of, must be an ultra-high-density energy storage medium! An extremely precious cosmic mineral!
"Wait, that is to say, there are such precious energy minerals in the interior of the moon, will it..." Nie Yun looked at the countless black stone pillars.
Is this a mining area?!
