<h4>Chapter 40: The Book of Arrays</h4>


    "How can you have a sense of terracotta warriors and horses..."


    The rhizome group spreads non-stop, allowing the rhizome to cross the vertical from the interval between these cubes.


    The roots of the rhizome extend out, and they skillfully plunge into the cube, carefully secrete the connecting protein, strengthen the cube itself, and clean up the dust blocks covering the surface.


    In this way, the rhizome system cleans up the ''cultural relics'' while growing and spreading at an unabated speed.


    After cleaning up those dusty rocks, the original appearance of the cube was presented in front of Huo Gu, with a length of two meters, a width of half a meter and a height of three meters. This data is not absolutely urate. The side length error between each cube is about one to three centimeters. The material is the same as the metal wall. Maybe this is also the array can be soplete. The reason why there are hundreds of millions of years.


    It can be seen that the things in this cube array are not the same as the cubes seen before. In terms of appearance, these array cubes are more like tombstones.


    On the surface of these repaired cubes, there are countless lines, which are not formed naturally. It is not that Huo Gu, an experienced guy, finally made a mistake, but the lines that these cubes originally came with.


    These lines arebined on the surface of the cube into geometric patterns of simr size. Each pattern upies an area of four centimeters square meters on the surface of the cube, and is arranged neatly in rows. Between the geometric figures, there are scattered symbolsposed of dots.


    Obviously, this is a text, an unknown word that ispletely different from humannguage.


    "This should have nothing to do with the tombstone, which is more simr to the tes in the tomb specially used to record important information, that is to say..."


    Huo Gu looked around, and the whole array was endless. Even if Huo Gu mediated the eye distance, its scale far exceeded that of any tombs on the earth.


    "Is this a book?"


    How to keep the information longer?


    This is quite a difficult thing, because in this universe, entropy is everywhere, and natural erosion will definitely destroy the stored readable information into uninterpretable noise. The difference is nothing more than the length of time.


    On earth, there is only one way to preserve information on a time scale of hundreds of millions of years - to engrave words on stones.


    It is not really using stone as the carrier of information, but a metaphor, that is, ''recording information on a solid that is extremely difficult to change''.


    Obviously, the intelligent life that was burning words on the cube array thought of it with the human beings on the earth, so it made such a huge ''book of arrays''.


    "It''s a pity that I''ve never been good at deciphering this kind of thing."


    Huo Gu stared and looked at the words on the cube with regret. Although he was born in archaeology, it focuses more on improving the excavation skills of those cultural relics. If it is an ancient text of the history on earth, it has a little foundation to read the general meaning, but for alien words without any foundation, it is really ipetent. For strength.


    Deciphering apletely unfamiliarnguage really requires a scientific research team specializing innguage and a national mainframeputer.


    Put aside the matter of the cube array for the time being. Huo Gu turned his attention to the rhizome that spread all the way forward. At this time, the rhizome finally spread out of the cube array. Huo Gu roughly calcted the scale of the cube array, 100 square kilometers, which is equivalent to 14,000 football fields. Area.


    At the farther end of the cube array, Huo Gu can see two thin lines in the distance, like ropes erected between heaven and earth.


    "There is another seawater column?"


    Huo Gu looked at his current distance from thest water source. Although it is still within the eptable range and can be solved by expanding the transportation volume, since there are more supply points that can relieve logistical pressure,


    That''s not a bad thing.In order to save organic materials, Huo Gu gave priority to the rhizome system to cover two distant thin lines.


    However, this time the thin line made Huo Gu puzzled. The thin line became thicker in Huo Gu''s vision, but the figure was still blurred. It seemed that there was still a long distance between them, and both thin lines were like this.


    Huo Gu immediately noticed this apathy.


    "It''s strange that the crack on the top floor is rtivelyrge, and these two columns of water are thicker than the previous one?"


    The answer will soon be revealed. The spread of the rhizome continued, spreading for about 40 kilometers, and finally extended the rhizome to the position of two pirs.


    These two pirs are not water columns, or even have nothing to do with water. They are the supporting columns that support this huge underground void, which is a giant pir with a diameter of one kilometer.


    At the farther end of Huogu''s current position, there are also vertical thin lines distributed on both sides. It can be guessed that it is also a support column simr to the current position.


    "The pirs here seem to appear frequently in the field of vision. Why can''t you see any supporting pirs in the previous distance?"


    Huo Gu has traveled almost more than 370 kilometers so far. However, he has not seen a simr giant support for the support column at this distance.


    ording to the structure of the underground void currently observed, there should be a supporting column in the distance that Huo Gu passed, so the question is, where are those huge pirs?


    Just as Huo Gu was meditizing, he inadvertently saw the cube array that had beenpletely upied by the rhizome system, and suddenly realized.


    Obviously, the construction of this huge cube array requires a huge amount of alloys that canst for hundreds of millions of years, so where is the source of these materials?


    It is impossible to dismantle the metal wall, because it is underground, and at that time, the possibility ball was still in a molten state. The whole is a giantva ball. Removing the metal wall is purely a death-seemination.


    Then there is only the support column that uses the same material, because it is the form of the that is still in apletely molten or semi-melted semi-solid, and the pressure cannot be asrge as the underground pressure of a solid, which makes a point.


    "So, what is this underground void...?"


    Intelligent life makes something, which generally gives a certain purpose in it, and like the underground void in the depths of Huo Gu, this technology can''t even be done by the human world. It is already a big project at the level of civilization, so this void is by no means the product of the idle guy who is boredom.


    Not to mention the ''Book of Arrays'' that covers an area of 100 square kilometers.


    So what is the meaning of this ce at the beginning of construction?
