<h4>Chapter 38: Excavations</h4>


    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 regr tri-edged cone, which is notrge, about a few centimeters in size. The vertebral body extends under the rockyer, which is easy to associate with the sharp part of the top of an object buried in the rockyer.


    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 rockyer, because the tri-edded cone is far harder than the surrounding rock, the root forms a ''V''-shaped shape in the rockyer, which sessfully attracted Huo Gu''s attention.


    Although there are many ores in the rockyer that are harder than the rockyer, it is really rare to think of such a regr shape.


    Huo Gu didn''t think too much, but just excavated the ce 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 regr 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 itsponents.


    "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 ce of basicva, and it is normal for arge number of metal elements of various types.


    In order to further confirm his ideas, Huo Gumanded 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 urate to the molecr 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 triangr cone body became less regr, although it was still angr.


    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 excavationpletely, which may be caused by obsessivepulsive disorder or because of upational 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 idents have been avoided by Huo Gu in advance. The excavation work ising to an extremely fast speed and is presented in front of Huo Gu.


    It was a metal te, 30 meters long and 82 meters wide, with a certain curvature, and the shape of the edge is irregr, like fragments of paper torn by the naughty child at will.


    The thickness of each part of the metal te 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 nce, 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 te is not straight, it is generally simr to the in hillside, with quite small fluctuation, while on the other side, there are arge 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 prated 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 te.


    The roots of the rhizome system prate the metal te, which is easy for them. Although the metal te is harder than the rock, it is alsoposed of molecules. As long as the gap between the molecules can be explored, the roots can easily prate.


    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 te and calcte how long the metal te 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 te is inconsistent. In such a long span, the chemical reaction in the strata will still cause erosion to the metal te, so the thickness bes inconsistent.


    However, this cannot exin the phenomenon that the metal te 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 tes.


    The matter in this void came to an end for the time being. Huo Gu continued to explore other voids. During this period, nothing simr to the metal te 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 hade 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.
