Flying civilization. Camelin star system. There is a huge planet here, with a diameter of 27,000 kilometers, a circumference of 84,800 kilometers, and an area of billion square kilometers, which is more than 4 times larger than the earth. The entire planet is surrounded by five suns. This is a five-body star system. Its disadvantage is that the surface heat is huge. But the advantage is obvious, there are many energy sources. As a second-level civilization, it will not be afraid of this level of heat energy. In fact, this is a good energy point. After Yan Xia and other Qiluo people arrived at the ground here, they found that the ground here was covered with sand.
However, when he stepped on the ground, he felt that the ground was not as soft as sand. He squatted down and picked up the sand on the ground. These sand grains are actually not sand grains at all, but creations. They are complete dodecahedrons, scattered on the surface of this planet, with a thickness of less than 10cm. Haru saw Yan Xia's expression and said, "These are called Grid Z, and their function is to collect light and heat energy." "The Grid Z on the surface of this planet will be collected every time it is full of energy, and then it will be rotated after absorbing the energy." "It brings considerable energy and can meet the daily needs here." Yan Xia roughly understood what it was like. In fact, collecting energy in this way is not efficient at all. As Haru said, it can only meet daily needs, not industrial needs, nor scientific research needs. But this thing itself should not be difficult to manufacture and maintain. Flying civilization is roughly just used to cultivate sentiment? Yan Xia doesn't quite understand. But it is indeed beautiful to cover the surface of the planet with sand. These Grid Z crystals sparkle in the sun, and it feels like you will get glare if you stay here for a long time. Flying civilizations, as always, arrange their living places underground. They may have become accustomed to such a life. Yan Xia is a little curious. "Why did you choose microscopic in the first place?" This question actually exists in the history books of flying civilizations.
But Yan Xia thinks there should be more than one reason. Haru thought for a while and said, "It should be that the original ancestors felt that we were too weak. If we created macroscopic technological creations, they might be discovered by other civilizations in the universe." "In the early days of civilization, some spacecraft wreckage was actually found in the universe." "From that period, our ancestors knew that there were other higher civilizations in the universe." And the microscopic. Will not be discovered. So the flying civilization turned its research direction to the microscopic. Of course, at that time, the flying civilization was actually entangled for thousands of years. Some people support the microscopic, and some people support the macroscopic. But at a certain period, microscopic technology broke out. The macroscopic technology began to be gradually submerged. This is that period of history. Haru told Yan Xia without hesitation. In fact, these histories can trace the source of the flying civilization, and through these histories, the fragments of the flying civilization can be supplemented step by step. After collecting them, perhaps it is the key to open the flying civilization. But Yan Xia didn't have this idea. Civilization will evolve countless times in the continuous process. Many ancient things will be submerged. From the 18th century to the 21st century, it took only two or three hundred years for humans to abandon most of the feudal customs and only retain the parts that are beneficial to themselves. If a civilization has developed for hundreds of thousands of years, and even explored the universe for hundreds of thousands of years. Their changes have already reached the level of earth-shaking. The key of history can indeed open a door. But civilization has more than one door. Yan Xia came to a small earthen slope on the surface of the planet with Haru and others. Only now did he realize that the surface of the planet was surprisingly flat. It should be that the flying civilization flattened the entire surface of the planet when developing this planet. Of course, there are also factors of the planet itself. The greater the mass of the planet, the greater the gravity.
When the gravity is greater, the rounder the planet itself is, and the mountains on the surface will not be so huge. Just like the highest mountain in the solar system is on Mars. If it is the earth, it can't bear a peak of tens of thousands of meters. The surface of this planet should have been relatively flat, and the highest mountain according to Yan Xia's guess is only one or two kilometers. In order to better absorb solar energy, or for construction. The flying civilization razed this place to the ground. This small earthen slope is only two or three meters high. Haru should have been here, or the entire flying civilization's buildings... The entrances are similar. It walked to the hillside naturally, and the closer it walked to the hillside, the smaller its body became. This looks a bit like Doraemon's shrinking tunnel. But the distance is actually very different. Yan Xia also walked towards the earthen slope, and his body was also shrinking. He could clearly feel that there was a layer of force field covering the surroundings. This force field would act on the atomic level and squeeze the atoms. In other words, at a smaller level, the whole body would shrink. When he was so small that the dodecahedron that was like a grain of sand just now became as huge as a tall building, his body stopped changing. At this time, the whole team also became smaller. They continued to move forward. Through the gaps between the dodecahedrons, we came to the earth slope. There is an obvious metal passage on the earth slope. It looks very huge. But if you look at it from a macroscopic perspective, it is actually smaller than the surrounding dodecahedrons. They entered the metal passage. The metal passage is transparent and emits a metallic blue luster every once in a while. Haru told Yan Xia that it was radiation. It's just that the amount of radiation is very small. After passing through the metal that makes up the pipe, it will make some fluorescent substances mixed inside the metal glow. Yan Xia doesn't get the beauty here. Haru likes this design very much. Sure enough. Even in terms of practicality, technological products are almost the same.
In things like art, the gap between civilizations is still very different. The passage is not long. When he reached the end, he saw a huge world. This world has sunshine and sky. And the ground is endless red soil, the surface of the red soil is full of messy crystal clusters, and all kinds of purple plants grow around the crystal clusters. These plants look like sponges. It's not the kind used for washing dishes, but the kind of sponge that grows on the seabed. The whole world is still relatively bright, and it looks like a relatively barren desert in another world with rare treasures. Haru flew up to the sky and looked into the distance. Then he landed again, showing joy and saying to Yan Xia: "Welcome to Camelin!" "This is a beautiful second-class city!"
