Like the earth, the interior of the moon also has a layer circle structure. From the center to the lunar surface, the moon can be divided into three layers: the lunar core, the lunar mantle and the lunar shell.
The thickness of the lunar crust and mantle add up to about 1000 kilometers, and Nie Yun is now at the junction of the lunar mantle and the lunar core!
These black stone pillars are equivalent to spreading the moon's core and mantle, forming this underground world.
Nie Yun guessed that perhaps at the beginning of the formation of the moon, a unique cosmic environment that can form energy crystals appeared at this position, and then it was discovered by a cosmic civilization, and the energy crystals were mined out by means of large-scale mining.
And the rest is just slag
Thinking so, Nie Yun's heart is a little unbalanced, which is equivalent to that you had a lump of dog shit at the door, but you were trampled by passers-by a before you went out!
Without this hateful passerby a, the lucky one should be his own!
My energy crystal! My heart hurts
wait! But there's something wrong. In such a huge mining area, why haven't I been jumping on people's heads for so long?
When planting mushrooms, it's equivalent to beating gongs and drums and setting off firecrackers at people's door every day. Can aliens tolerate it?
Is it a year beast, frightened?
Looking at the traces here, it seems... It's very old. It doesn't look like someone has been active recently. Has it been completely mined and evacuated?
Nie Yun didn't find any other abnormalities around, so he followed the already fuzzy traces on the ground and prepared to follow the steps to find out each other's mining base.
He sa Yazi ran wildly in this huge underground world. The open terrain and the ideal drag racing environment without resistance made Nie Yun quickly soar route 11 to more than 600kmh. The dragonfly skimming the water is generally turned into a residual shadow flying over the land, and the speed is still improving!
An hour later, the shadow of a huge base finally appeared in front of Nie Yun.
"Boom..." Nie Yun's feet ploughed out two deep gullies on the ground and extended for several kilometers. Only then can he stop more than ten kilometers in front of the ruins, leaving a long-standing dust belt behind him.
What appeared in front of Nie Yun was the remains of a huge mining base. Yes, the remains!
That shabby and desolate scene definitely doesn't look like it's still running.
Nie Yun's pupils contracted and drew his eyes closer to observe the interior of the ruins. In addition to some semi-circular functional buildings, the base was a row of strange machines nearly 100 meters high in the open space, and a semi-circular pit was in the center.
Seeing that there was no sign of danger, Nie Yun jumped into the base.
There are no walls or gates built here, which are transparent on all sides, and these buildings have no obvious defense facilities. Obviously, in this safe underground depth, the owner of the ruins has not done anything to kill one stone.
Although it seems that it has been abandoned for a long time, and some buildings and mechanical equipment have collapsed, which seems very dilapidated, the main body of the base still maintains a certain integrity.
Nie Yun first came to those very conspicuous huge machines.
This is a kind of six legged construction machinery that looks very bloated. It looks like a mechanical ant with two drill arms. It looks like an engineering robot for mining. The bloated body should be a storage space specially designed to facilitate the transportation of mined minerals.
"Bang bang!" Nie Yun tried to tap a mechanical foot of the mining ant in front of him.
"Jam!" a crisp sound similar to glass fragmentation came. A crack directly appeared on the knocked mechanical foot, and then the crack spread rapidly.
"Click!" "click!" "boom!"
In Nie Yun's staring eyes, the mechanical ant first broke a mechanical foot, and then the remaining mechanical feet broke like a chain reaction. Finally, the whole mechanical ant tilted and collapsed and turned into a pile of dust and parts in front of Nie Yun.
"Er..." Nie Yun was silly. How long will it take for the alien's steel materials to age like this? You know, this is a vacuum environment. Pinch your fingers. It must have been tens of thousands or even hundreds of thousands of years?
Tens of thousands of years ago, humans were still drilling wood for fire in caves, right? These aliens have the patience to observe humans for 10000 years?
He was even more confused. Then he ignored the machinery here and turned into those semi-circular buildings to find clues.
"The warehouse... Is empty! Well, as expected. It can be seen that these aliens are greedy!
This is an energy pipeline? He didn't even leave me a generator! Hum! What a small family!
Here... It seems that a robot automated production line has been demolished. How is it an ant? Are you ant stars? What hobbies? "Nie Yun make complaints about the sour taste of grapes.
As a result, no trace of alien life was found, but it confirmed the other party's extraordinary love for ants.
The discovered robot automatic growth line is a small ant robot only 2 meters high. It seems to be a basic unit for construction and maintenance, with some broken robot debris inside.
Seeing no other clues, Nie Yun tried to devour a relatively complete ant robot carefully. After a long time, he opened his eyes and frowned.
The information obtained from the robot is not much. Its chip uses a completely strange program compilation language, and of course it is not binary. Without a large number of data samples, Nie Yun can't completely decipher it.
Just like when Nie Yun first saw those abstract paintings, he could clearly see the color of each molecule in the painting, but combined... Who knows what ghost he painted?
In addition, a considerable part of the chips inside the robot have been aged and damaged and can not be repaired. The broken information has brought greater trouble to Nie Yun's decoding work.
Therefore, in addition to some empirical values of "multi legged robot" architecture and materials, the biggest gain at present is to find the command release source to control it.
When he came to the huge semicircular pit in the center of the base, he could see that there were dense lines and pipes in the pit, but it seemed that a section had been cut off by Sheng Sheng. That's all.
"There should have been a spherical base core here, that is, the alien mining vehicle! Has it been recycled after mining?
In other words, what is left are aging equipment or cheap tools that have no recycling value? "
Hey! Isn't that a little out of line? Even if you eat dry and wipe it out, you should lick the dishes you have used before you leave. Is it erha's!
Nie Yun's righteous anger is hard to calm!
