Chapter 39: Chapter 39 Artificial Things
The rhizome system is expanding with all its strength, up, left, right and forward, and the extended distance has reached almost ten kilometers.
Huo Gu didn't see anything like a support pillar along the way, and his curiosity couldn't help but be more vigorous.
"The air environment is dominated by oxygen, and the proportion in the air is 67%..."
This is an amazing proportion of air. You know, during the period when the earth has the highest oxygen content, the proportion of oxygen in air will only reach 35%.
Fortunately, Huo Gu can adjust the cells. When other organisms come here, they will immediately cause oxygen poisoning due to excessive inhalation of oxygen.
Huo Gu observed the surrounding environment. To be honest, this super-giant hollow is flat beyond Huo Gu's imagination. If you just look at a small place, it is indeed uneven, but if you look at it, it is a straight surface, which does not seem to be formed naturally at all.
Even if Huo Gu's attention turned to other places, the expansion of the rhizome system did not stop. In a faint time, Huo Gu noticed a columnar object in front of him.
Support column?
Huo Gu came up with such an idea.
After hesitating again and again, Huo Gu did not slow down the coverage of the rhizome system. Of course, his vigilance against the columnar object could not be relaxed. Huo Gu was ready to fight at any time.
It's not that Huo Gu's vegetation is a soldier. In this strange environment, he encountered such a strange thing, especially who was chased into the underground void by some unidentified creatures before. Huo Gu can no longer put the underworld of this planet into the earth's Hades.
After a period of time, the columnar object changed from a vertical thin line to a vertical column. Huo Gu began to adjust the vitreous body of his eyes and turned to the true face of the column.
However, to Huo Gu's disappointment, the columnar object was not a solid, but a liquid state. It was a water column formed by the falling seawater of the ocean above. Huo Gu could also see sporadicly floating gourds and titanium snails floating from the pool under the water column.
"Although these organic materials are not a good thing to send charcoal in the snow, the icing on the cake is not a good thing, and with this water source, the supply and transportation pressure behind will be much smaller."
A conical creature quickly perchred in this water, used to collect organic materials in the seawater, and the rhizome continued to spread forward.
This expansion lasted for a period of time, and Huo Gu finally encountered the edge of this super-giant void, but not the front, but the rhizome of the expansion in the upper and left and right directions, reaching the edge at a distance of about 100 kilometers.
The rhizome that came into contact with the edge temporarily stopped spreading and expanding, and samples of these marginal substances were collected for on-site analysis. Then, the results obtained complicated Huo Gu's mood.
On the left and right sides are standard andesite, coarse rock, coarse rock, alkaline long coarse surface rock and other neutral volcanic rocks, but the top is a huge metal surface, which is the same as the metal plate excavated in other caves before. It seems to have become very rough after a long time.
Huo Gu then commanded the left and right rhizome to break through the volcanic rock. As a result, as he continued to go deep into the volcanic rock about one meter thick, the same metal surface appeared.
"Analyze the constituent elements of these metals and the half-life time."
Repeating what he had done in another underground void, Huo Gu got the answer - 800 million years, the same time as the metal plate.
Not only time, but also the components are the same, but there are nuances in proportion.
"It seems that the metal plate should be part of this metal wall."
"Well, this is really an artificial object..."
Huo Gu thought for a while and added another sentence.
"...It may also be a comet that fell on this planet."
Huo Gu thought of some comets that had been observed that most of the areas were covered with metal.
If it's that kind of comet,
When entering the planet, the metal will become a molten state due to friction with the atmosphere, completely wrapping the comet. If the comet keeps rotating at high speed when it falls, it is easy to form such a circular cross-section.This explanation seems to make a point, but the later discovery made this explanation untenable.
In the rhizome system that spreads forward and explored, a rather strange place was soon found at a distance of about 100 kilometers.
You can see a cube-shaped object, as if it was cut by hand, but it is integrated with the ground without any gap.
The position near the cube is a mound. On this mound, Huo Gu can see a round object that seems to be a wheel.
Where the cube and the mound are perpendicular to each other, there are three columnar columns, which are not connected to the dome. The diameter is about half a meter and the length is three meters. They look like an inverted test tube.
There is nothing else about these things.
Huo Gu brought his perspective closer and looked at everything here. It has basically determined that these are not natural. The underground void it is currently in is created by intelligent life.
Roots analyzed the material of these objects.
is the same as the underground hollow metal wall and the unearthed metal plate. It is better to say that it is because of this metal material that it can span hundreds of millions of years. Now in front of Huo Gu.
At that cube, Huo Gu used his roots to clean up the dust that was attached and had clumped into rocks. It was because of this 100 million-year-long accumulation of dust that the cube seemed to be completely connected to the ground.
After carefully cleaning the dust blocks, Huo Gu got several geometric figures from the side of the cube, and then it cleaned up several other dust-up objects.
After learning about the situation in the mound through roots, Huo Gu basically determined that the mound should have been a vehicle-like transportation tool, but finally could not withstand the erosion of the years, so it became today's mound.
The three stone pillars, Huo Gu speculated that they were some kind of machine. The interior is a hollow structure, and the silicon component accounts for half of them. There is no geometry similar to that exists on the cube.
Huo Gu can roughly guess what the purpose of this machine is. People are iron rice or steel. If they don't eat, they will die. In this desolate area without a village or a shop, what else can this machine do besides ensuring food and allowing intelligent creatures to continue to maintain their lives?
For the cube, Hogu began to speculate that it was a coffin, a dormant cabin and so on. However, the rhizome did not find a particularly obvious gap in the cube. Obviously, there was no such thing as a lid, so the guess was overturned.
The spread of the rhizome forward continues, and it can't reach the edge. Huo Gu will not ask the rhizome to stop the spread.
About 30 kilometers away from the strange place, a huge cube square array appeared in front of the rhizome group, where tens of millions of cubes were displayed.
