Rectangular cuboids are very common objects in geotry, and even among real objects there exist many rectangular cuboids, such as a box, a case, a pack of cigarettes, a cabinet. These ordinary things all have the structure of a rectangular cuboid. Even now that Xiao Yu has beco a Level 6 Civilization, this situation has not changed.
But these rectangular cuboids, whether those of the human era or those of the present Level 6 Civilization, are not rectangular cuboids in the true sense, or one can only say they are rectangular cuboids in a fuzzy sense. Because they only look like rectangular cuboids. If slightly more precise detection thods are used, one can discover that they are rely objects of irregular shape. Perhaps one face has a slight tilt, or one edge is a little longer or shorter than the others. Because chanical manufacturing will always have error. Technological developnt can reduce error but cannot eliminate it completely.
The rectangular cuboid now before Xiao Yu, however, is not like those fuzzy rectangular cuboids. It is a genuine rectangular cuboid. Each pair of opposite faces is absolutely parallel. All pairs of opposite edges are absolutely equal. The two edges where two faces et are absolutely perpendicular. It has not the slightest error, at least as far as Xiao Yu can tell.
Its length, width, and height are in the exact ratio of three to one to one. Based on distance asurents, Xiao Yu asured the length of this rectangular cuboid as 9.3 ters, and its width and height as 3.1 ters. This data is extrely precise, neither a bit more nor a bit less. At least at present Xiao Yu cannot detect any error.
A thing without error is a frightening thing, sothing that exceeds the limits of Xiao Yu’s understanding. Xiao Yu does not know how such a thing could be made. Xiao Yu can now manufacture precision chanical components with error only at the level of five femtoters. One femtoter is one ten quadrillionth of a ter. This is a degree of precision unimaginable to humans of the Earth era, yet an error is still an error.
That is to say, Xiao Yu cannot manufacture a steel plate whose length happens to be exactly one ter. No matter how careful Xiao Yu is or how precise the equipnt used, the steel plate Xiao Yu manufactures will always be a little more or a little less than one ter. This is error, sothing that even a Level 6 Civilization cannot eliminate.
Yet at this mont the rectangular cuboid before Xiao Yu has no error. Its length happens to be 9.3 ters. Its width and height happen to be 3.1 ters, neither more nor less. Moreover, its surface is absolutely smooth. Even with Xiao Yu’s femtoter-level resolution, he still cannot find any bump or hollow on its surface.
In this respect it is very similar to the Droplet probe Xiao Yu encountered before. When Xiao Yu was still weak, upon first seeing the Droplet probe, he marveled at its seemingly absolutely smooth surface. But that was only relative to Xiao Yu at that ti. With his present detection capability, Xiao Yu can easily detect the surface material structure of the Droplet probe and thus know that it is not absolutely smooth. In fact, the Droplet probe already shows unevenness at the picoter scale. It was only that Xiao Yu at that ti could not detect these things.
Just an ordinary rectangular cuboid gave Xiao Yu a feeling of shock as if heaven and earth had been overturned. Xiao Yu had never imagined that in this universe there could exist sothing so precise, sothing without error.
Think about it. If the balls in chanical objects could present an absolute sphere with an absolutely smooth surface, if the teeth of two gears fitted together perfectly without the least friction, then to what height would the transmission efficiency of force reach. To what terrifying degree would the utilization of energy reach.
In such machinery, lubricating oil would probably be entirely superfluous.
“No, no, impossible. Error cannot be eliminated. This should be a truth of the universe. Even if this civilization has reached the level of a Level 7 Civilization, they absolutely cannot break this theorem. That must be it. The error of this rectangular cuboid is too small, so that with my present detection capability I cannot find it. That must be it. That must be it.” Xiao Yu murmured, doing his utmost to calm his surging feelings.
“Could this be the manufacturing capability of a Level 7 Civilization of the chanical direction. If they can manufacture such a precise rectangular cuboid, then what exactly is there that they cannot manufacture. No wonder, no wonder they could roam across hundreds of galaxies on the mass of a single star. For manufacturing capability to reach such a degree, this should be an extremity.”
Although using elental decay and matter-antimatter annihilation as energy sources can in theory achieve the complete conversion of a piece of matter into energy, in practical application it is not so. Xiao Yu has no way to utilize all this energy. In the process of chanical operation, unavoidable losses always occur. This is the greatest bottleneck that restricts increases in chanical efficiency, error. It is conceivable that if Xiao Yu could achieve complete elimination of error, or even only elimination at the level of this Level 7 Civilization, his energy utilization rate would make an enormous leap.
This Level 7 Civilization of the chanical direction, with a simple rectangular cuboid, was unscrupulously displaying its technological strength here and mocking this crowd of insignificant existences.
At this mont, the shock in Xiao Yu’s heart had turned into a feeling of powerlessness. Xiao Yu seed to see a tall mountain he could never cross standing before him. Now Xiao Yu could not even give rise in his heart to the thought of surpassing this Level 7 Civilization.
“This should be the ruin left behind by that Level 7 Civilization, right. Could it be that their ruin is just such a rectangular cuboid.” Xiao Yu thought, full of doubts. “Why have these powerful existences who are watching nearby not struck to seize it. Where has the Sweepers Civilization gone.”
Although it is a bit strange to use a rectangular cuboid as the ruin of one’s civilization, it is not unacceptable. At the very least, by studying the manufacturing process and materials process of this rectangular cuboid, one could bring a leap in the relevant fields of one’s own civilization. Moreover, as an artifact of a Level 7 Civilization, it ans that as long as one’s own civilization has not beco a Level 7 Civilization, one can continuously draw nourishnt from this thing. And science is originally a discipline in which one thing leads to another, at least for civilizations below Level 7. Therefore, in a sense, using this one rectangular cuboid to drive the technological progress of an entire civilization is not impossible.
Moreover, most importantly, if there truly exist various different developnt directions among Level 7 Civilizations, then for a Level 7 Civilization specializing in space technology, this thing, manufactured by another Level 7 Civilization, still has enormous value. So, in a certain sense, this thing would be greatly attractive even to a Level 7 Civilization.
Since its attraction is so great, why have these powerful existences around not made a move to seize it.
When circumstances are unclear, going with the crowd is the safest approach. Xiao Yu wisely suppressed the thought of making a move to take it, even though this thing had an attraction for Xiao Yu so powerful it was almost impossible to refuse.
“This is the creation of a Level 7 Civilization of the chanical direction. The Sweepers Civilization’s Neutron War Star is the creation of a Level 7 Civilization of the extre stellar body direction. The two-dinsional fragnt of a spatial lifeform you obtained was manufactured by a spatial lifeform incorporating a portion of the technology of a Level 7 Civilization of the space direction.” At this mont, sowhat unexpectedly, Xiao Yu received a ssage from Technology Taihao.
Xiao Yu did not find it strange that Technology Taihao knew these things. In fact, from birth until now, Xiao Yu had never completely escaped the influence of the Taihao Civilization.
A slight stir arose in Xiao Yu’s heart.
Xiao Yu noted two terms. One was Level 7 Civilization of the extre stellar body direction, and the other was Level 7 Civilization of the space direction. Quite to Xiao Yu’s surprise, the Neutron War Star that dominated the Milky Way Galaxy for tens of millions of years was actually a creation of a Level 7 Civilization of the extre stellar body direction, and the two-dinsional weapon he had developed actually mixed in a portion of the technology of a Level 7 Civilization of the space direction.
These two terms completely confird Xiao Yu’s conjecture.
“It seems my speculation was correct. There truly exist many different developnt directions among Level 7 Civilizations.”
“Taking the initiative to tell this information, is the Taihao Alliance proactively conveying goodwill to . Very good. Although for so unknown reason the Taihao Alliance incited the Arboreal Race Alien Beast to attack , at least on the surface our two groups have not completely fallen out. Then under the present situation, it is only natural for us to form an alliance. Very good. As long as the Sweepers do not co, the two Alien Beasts, even adding the Guardian Civilization, are not our match.”
“Why have the Sweepers not co? What are you all waiting for? Why has no one struck to seize this rectangular cuboid?” Xiao Yu asked three questions in succession.
All these questions concerned the present situation. Not one touched on the grievances between Xiao Yu and the Taihao Civilization. Xiao Yu also used this to state his stance, naly that whatever grievances exist between us can be discussed after this event.
Xiao Yu believed that Technology Taihao would certainly understand his aning.
But to Xiao Yu’s surprise, Technology Taihao’s answers to these three questions were all the sa, and unusually concise.
“Wait.” said Technology Taihao.
