Chapter 2039 Exploration of the Center of the Earth
  While humans in this world are utilizing the water resources in the ocean, they are also exploring why the water in the ocean does not solidify. Some people think that the upper ice sheet plays a role in keeping warm. For people in this world, the perception of soldiers is not cold.

In terms of ice, which is close to melting temperature, it is actually quite warm from the perspective of human body perception. After all, the soldiers in this world are actually hotter than ordinary delayed steel. It's just that their characteristics in this world are more resistant to high temperatures, which makes them always appear in the form of ice without melting.

Under this special physical environment, people take it for granted that the ice layer can retain heat like a large quilt.

In fact, not only in this world, but also on the earth, ice can also keep heat. Houses made of snow in extremely cold areas can have a certain warming effect, at least maintaining the internal temperature at Around 0 degrees, the most important thing is to be able to block the cold wind from outside.

The efficiency of flowing airflow in taking away heat is much faster than that of normal gas. Is this one of the reasons why you feel cool when the wind blows in summer? This is also one of the reasons why air fryers can cook food quickly.

However, the ice layer simply insulates the underground and cannot explain why there is so much water in the underground. Scientists gradually discovered that the ice layer is getting thinner and thinner in the water. To be precise, the ice layer in the water will melt slowly, but the overall thickness of the ice layer will remain constant.

This is the feedback result given by the detector placed in the deep sea. The ice in the area calibrated by the detector began to thin, but after detection through echo, positioning and other methods, the overall thickness of the ice remained unchanged.

That is to say, the ice layer below is melting slowly, while more water vapor above condenses on the surface of the ice layer, and then solidifies into part of the ice layer. The entire ice sheet circulates at an extremely slow speed.

After learning this, people in this world boldly guessed that there is a source of high temperature underwater. It is this source that heats the seawater and keeps the seawater at a high temperature. Only in this way can it be maintained like this all the time. A large expanse of liquid seawater.

And this conjecture is not completely without evidence. According to the exploration of deep water by people in this world, it can be determined that the temperature under the water is higher than the temperature on the surface. This is an unreasonable phenomenon. Logically speaking, the density of water should be maximum at 4°C. The density will decrease at temperatures above and below this temperature.

Of course, this world will not have this four-degree scale, but another temperature scale. But this does not affect the properties of water. In other words, the water at the deepest point should be at this stable temperature, rather than the water temperature getting higher as you go deeper. This abnormal situation often means that there is a heat source in the mountain water, which heats the deep water and causes convection. This special situation occurs when the heat is not completely brought to the surface.

However, from the analysis of the existing exploration area, no underwater heat source has been found. The temperature of the rocks at the bottom and the water temperature at the bottom are almost the same. That means the heat source should be somewhere else, perhaps farther away in deep water.

At present, there are still too few areas explored by humans. Especially the deep sea is difficult to explore.

In the deep sea, the ice surface has penetrated deep into the sea water. Human beings can only dig caves one after another on the ice surface and survive in the caves. In fact, it seems that there are hundreds or even hundreds of ice layers suspended below the water surface. Thousands of meters thick, if you want to explore under the ice, it will be a quite large project.

One way is to penetrate the ice below and create a deep cave. This is relatively easy to do. The other way, which is more difficult, is to go around the ice from the side and go directly underneath.

This is more difficult, but can save costs. The problem lies in the depth of thousands of meters. Want to keep your own hull stable. rather than being crushed into pieces by water pressure. It is a very difficult thing, especially under the physical conditions of this world, the temperature of water is very high, and it is easy to flatten the existence in the water.

Under high temperatures, ordinary steel becomes extremely soft. Only some special materials can maintain their strength in high-temperature water. The configuration of these materials is obviously very difficult. At present, it is not difficult for humans in this era to create extremely strong materials above the water surface, but it is not difficult to create an existence of the same strength below the water surface. The difficulty was simply astounding.

Therefore, in this era, submarines that can dive into the deep sea have not yet been developed. What do humans know about the abyss under the ice? Now we can only speculate. However, the rapid development of science and technology has made the newly developed humans in this world more rational than the normal primitive world. They believe that the underwater world can also be explored and understood, but their abilities are still insufficient now.

They did not directly imagine the abyss as a place where demons live. In their imagination, there may be some creatures living in the abyss, but they are either very small in size or have difficulty coming to the surface of the water.

From their point of view, the pressure in the bodies of living organisms in the abyss should be very high, just like the human body is also under pressure. They have tried that if the gas is removed, the pressure in the human body will stretch the human skin very ugly.

In fact, this phenomenon is easy to discover. As long as you understand the principle of cupping, you can realize this. This is a physiological phenomenon caused by people living in an air environment for a long time. If they live in the deep sea for a long time, the pressure in the body should be higher. If they float to the surface, they are likely to explode directly and die. .

So in terms of physiological structure, although humans in this era are full of curiosity about the creatures in the abyss, they are not very worried about the invasion of creatures from the Yuan.

With the in-depth exploration of this event, human beings have begun to further develop under the water, and the direction of their development is somewhat different from what humans on earth imagined. When normal humans choose the direction of exploration, they tend to look toward space.

Even for people on earth, the deep sea is actually more unknown than space. The deep seabed is closer to us than space, but few people pay attention to exploring the deep sea. More attention is focused on space. It is as if everyone subconsciously thinks of the boundless space when they think of exploring unknown areas. . This is because we are humans living on the surface. We can see the starry sky when we look up, while the deep sea is a distant existence to us, at least from an intuitive perspective.

But for people in this world, it's just the opposite. They live in the deep sea, and when they lower their heads, they can see what seems to be an endless pitch-black abyss. Over time, their impression of the pitch-black abyss underwater is just like our impression of the pitch-black abyss. The impression of the starry sky is average.

So their exploration direction is downward. Although I haven't concluded that the thing under my feet is a planet. But according to their judgment, the temperature gets higher the further down you go. For them, there is no doubt that the high-temperature areas on this cold planet often contain more resources that can provide them with survival resources. The development of the underground is far more attractive than the development of distant space.

It has to be said that, to a certain extent, they have actually missed some opportunities by focusing their main development direction on underground development.

Although the stars in this world are quite dim, the sunlight emitted by the stars is ultimately the main source of energy for any world. If a large amount of sunlight can be gathered, a large amount of liquid water can be created on the surface of the earth and an area suitable for human survival can be created. A large amount of energy can also be obtained through this method.

In addition to conventional physics, there are some magical phenomena in this world. In other words, you can use magic and fighting spirit just like the outside world. It is possible to become a warrior or a mage, but humans are still cursed. Even in such a remote area, the number of humans who can become extraordinary is very small.

If development proceeds according to the normal trajectory, humans in this world should gradually develop from the barbaric era to the world of swords and magic. The existential power of a mage is easier to obtain. At least compared to summarizing a large amount of scientific knowledge, it is actually easier to gain power through self-cultivation. If you want to gain powerful power by summarizing natural science knowledge, then It must rely on a huge scientific research team and industrial system.

This is undoubtedly more difficult for humans who have just emerged from primitive society. But similarly, if we embark on the path of industrial development after coming out of the primitive era, the power gained by industry will develop at a speed far exceeding the speed of imitation development.

Although the speed of personal training is already very fast, it still takes several years for a mortal to be able to fight against firearms, and it must be talented and reasonably talented to do so.

For ordinary people, it is much easier to get a gun than to gain strength through such complicated training. This is one of the reasons why technology and magic are sometimes incompatible.

In a world with advanced technology, the difficulty of obtaining power is at least much easier than obtaining some power that is not particularly high level than practicing.

This is one of the reasons why the magic system in this world develops relatively slowly. However, as humans gradually explored the deep sea, the development of magic began to gradually flourish. It is mainly a matter of materials science, which is difficult to overcome in a short period of time, while magic has the ability to strengthen spells and the like. Materials can be enhanced through such spells. Above the ground, the role of these reinforced materials is relatively limited. After all, under normal temperature environments, humans can already create materials with considerable strength. The problem is that in the underwater environment, most humans now The materials that can be made are soft and fragile. If it can be combined with material-strengthening spells, then theoretically, materials with quite high strength can be constructed. Able to withstand high temperatures underwater.

Along the direction of material strengthening spells, some powerful mages have also developed spells such as projection magic, which can temporarily directly project recorded powerful materials, but the whole process will consume magic power, and more At this time, this strengthening ability should be based on some kind of existence, so that it will consume less when used.

After all, the extraordinary beings in this world grow up through trial and error. The most powerful extraordinary being may only be at the second level, or may not even be a high-level existence.

However, as some geniuses devote their energy to this aspect, it won't be long before legendary existences can actually be born. After all, the population base of this world has increased, and although extraordinary power requires the accumulation of experience, it relies more on personal talent.

Some races with only a few million people. It is also a population that can give birth to many high-level powerhouses. If there are more, it is normal to give birth to legendary powerhouses. The same is true for humans in this world. Although their current population base is still around one million, with the continuous expansion of their living space, it is only a matter of time before they reach tens of millions or even hundreds of millions.

There are no other ancient races here to hinder their development. They can continue to develop with this unique technology.

When Entropy saw the development of these humans, he did not feel that their development was a threat to all races in the wild. The biggest reason is that the human technology tree in this world is crooked. It is a technology tree based on the special point of the water temperature in this world.

If they explore the outside world and successfully connect with other worlds, they will find that except for some knowledge of mechanics and mathematics, most of the technologies they have summarized are useless. After all, water is almost indispensable in industrial production. , and if the characteristics of water change significantly, it will be enough to completely collapse the industrial system.

In such a small world, no matter how powerful they develop, they will be knocked back to their original form after leaving. And the civilization that such a world can support, even if the population reaches hundreds of billions, is beyond any other civilization. The number of individual races in the prehistoric world, after all the outsiders are beaten into ordinary people, will have minimal impact on the entire prehistoric continent. However, although he felt a little impatient when watching the development of human beings, he kept watching. After all, he lost 1/6 of the innate spiritual treasures because of laziness last time, but he would not be distracted this time.
