As the collectors of the seabed gradually adapt to the seabed environment, the rhizome spread speed in the underground void has also returned to its previous efficiency.
Huo Gu continued to observe the collection of the collectors through the rhizome system. After determining that there would be no more problems for the collectors, he was relieved to focus on exploring the underground void.
The rhizomes in the void soon covered half of a previously discovered underground void.
The void brought a lot of surprise to Huo Gu, in which Huo Gu found a crack with continuous influx of sea water, as well as gourds and titanium snails scattered on the ground. Obviously, this gap is also a passage to the upper seabed.
In this way, Huo Gu's channel for water can be multiplied by two, and there is no need to widen the original channel.
Of course, if it's just this kind of thing, it won't make Huo Gu, who has experienced so many things, feel 'shocked'. At most, it's just a surprise. What really surprises it is something found in the void.
It is a regular tri-edged cone, which is not large, about a few centimeters in size. The vertebral body extends under the rock layer, which is easy to associate with the sharp part of the top of an object buried in the rock layer.
It is still because of the root of the rhizome system that the rhizome needs to be fixed in the position of the root. When the root is plunged into the rock layer, because the tri-edded cone is far harder than the surrounding rock, the root forms a 'V'-shaped shape in the rock layer, which successfully attracted Huo Gu's attention.
Although there are many ores in the rock layer that are harder than the rock layer, it is really rare to think of such a regular shape.
Huo Gu didn't think too much, but just excavated the place with pure curiosity. Unexpectedly, he really discovered such a shocking thing.
looking at the trigonal pyramid exposed from the rock formation, Huo Gu suppressed the excitement in his heart and said his thoughts in disbelief.
"Artificial products?"
There is no other reason. This shape is too regular and doesn't look like a natural product at all.
Huo Gu rubbed some molecules on the tri-eddered cone with a root and analyzed its components.
"Iron?"
"No, there is still carbon in it. Is it steel?"
"That's not right, and potassium, titanium, silver, lead..."
More than 20 elements have been found in it one after another. However, Huo Gu still can't make a conclusion immediately. The void was once a gathering place of basic lava, and it is normal for a large number of metal elements of various types.
In order to further confirm his ideas, Huo Gu commanded the rhizome and started his old job - archaeological excavation.
Excavation from the roots of the rhizome is far more efficient than human beings excavating with small brushes, and they can be accurate to the molecular scale. The damage to the excavations is far smaller than that of small brushes.
To Huo Gu's slight disappointment, the downward part of the triangular cone body became less regular, although it was still angular.
This means that the possibility that the excavation is a natural product increases.
Although his enthusiasm was seriously hit, Huo Gu decided to dig out the excavation completely, which may be caused by obsessive-compulsive disorder or because of occupational diseases.
Roots' ability is very strong. In addition, Huo Gu, an archaeological veteran, is operating. The excavation work is progressing very smoothly. All kinds of possible excavation accidents have been avoided by Huo Gu in advance. The excavation work is coming to an extremely fast speed and is presented in front of Huo Gu.
It was a metal plate, 30 meters long and 82 meters wide, with a certain curvature, and the shape of the edge is irregular, like fragments of paper torn by the naughty child at will.
The thickness of each part of the metal plate is not uniform. The previous measurement was six meters, but the measurement results at other edges were eight meters, seven meters and five meters.
In short, the thickness is in the range of eight to five meters.At first glance, it seems to be a naturally formed object, but Huo Gu keenly noticed a rather interesting feature on the excavation.
Although one side of the metal plate is not straight, it is generally similar to the plain hillside, with quite small fluctuation, while on the other side, there are a large number of potholes, potholes of different sizes, just like the surface of the moon, and some pits are connected to the reverse side, which looks like they have been penetrated by something.
"Is it..."
Huo Gu seemed to understand something. The horror was mixed with disbelief, and he couldn't help muttering to himself.
"No! It's too early to make a conclusion. Let's determine the time of the metal plate.
The roots of the rhizome system penetrate the metal plate, which is easy for them. Although the metal plate is harder than the rock, it is also composed of molecules. As long as the gap between the molecules can be explored, the roots can easily penetrate.
A sample of the excavation was removed by the roots, and
then involved in the rhizome system. Huogu wanted to analyze the proportion of half-life atoms of the metal plate and calculate how long the metal plate has gone through.
Soon, the results came out.
"Hual hundred million years..."
A number that makes Huo Gu feel tongue-ppointed. Dinosaur fossils are only 200 million years old. Now it can probably understand the reason why the thickness of various parts of the metal plate is inconsistent. In such a long span, the chemical reaction in the strata will still cause erosion to the metal plate, so the thickness becomes inconsistent.
However, this cannot explain the phenomenon that the metal plate is pitted on one side and not on the other.
Huo Gu once again thought of 'artificial objects', but there was no conclusive evidence. He did not dare to be so arbitrary, and nature was not without the conditions for the formation of such metal plates.
The matter in this void came to an end for the time being. Huo Gu continued to explore other voids. During this period, nothing similar to the metal plate was found.
A kind of emotion that is unclear, I don't know whether it is disappointment or something else. With Huo Gu's mind now, maybe it is subconsciously looking forward to it as an artificial object.
"Next is the exploration of the big void."
"I hope to find something."
The rhizome that had been stopping at the entrance of the big cave finally had a movement again, and the transportation problem of water had long been solved. Under Huo Gu's instructions, the rhizome spread like a broken bamboo.
Entering it through the vision of the rhizome, Huo Gu once again experienced the empty huge space. If it hadn't been for the wall behind him, Huo Gu even felt that he had come to the surface again, a ground that could not be seen.
"My God, how on earth did this void form?"
Huo Gu rose again and became curious about this void.
