Douluo see you soon

For a civilization with no shortage of energy, the speed of construction will be very fast. As time goes by, after ten years, the highway from the land to the ocean has been completely built, including the one on the surface.

The highway and the underground highway are also built next to the underground highway, which uses magma energy and Stirling engines to provide energy at the same time.

When designing this railway, the designer considered that when a large amount of materials and people need to be transported, the trains running on the railway need to be very wide.

In this case, the distance between the rails is enlarged to a considerable extent.

In fact, humans living on earth can find that the distance between real railways is actually a bit narrow if you look closely. This can be seen from the shape of the current railways and trains. The train carriages are far apart.

It is much wider than the spacing of the track. In the earliest times, the train carriages were not like this, but were almost the same width as the track. This change occurs now, obviously because the vehicles are in order to load more

Cargo and passengers had to undergo this level of modification.

This standard is actually the spacing between tracks from the ancient Roman era. When people at that time designed the tracks, they did not consider how powerful the future trains would be in carrying capacity or how wide the tracks could bear. Compared to

People in this world are experiencing technological development at a rate similar to a technological explosion. When looking at problems, they tend to look to the future. Some technologies may not be very suitable for today, and some designs may not be suitable for today.

It may even affect the speed of industrial development, but if it is suitable in the future, it is likely that related designs will be adopted.

Human beings in this world also had the same idea when designing railways. When they first designed it, it was actually difficult to make a train that could span such a huge span of track. The materials science at that time was still not very advanced.

It was not as developed as it is now. If the train is so wide, there may be shaking in the middle. If too much cargo is loaded, the carriage may even be deformed. So the chassis of the car at that time must be made

Just be very thick.

But with the development and advancement of technology and materials science, cars have begun to become stronger. Even if it is above magma, Mercedes-Benz will not soften and deform due to high temperatures. The current track spacing has become appropriate, and

This design also makes it easier for them to transport large amounts of cargo to ocean locations.

This railway line has almost become a lifeline. After all, the cost of transportation by rail is much lower than the cost of transportation by entry.

After all, if you drive on the road in this world, you will consume energy. The car must be filled with hydrogen tanks or biogas tanks. Then, the Stirling engine on the car will be treated through the high temperature of combustion and the high temperature water left after combustion.

Heating, and these fuels are quite expensive.

In contrast, the train travels directly on top of the magma and uses the temperature difference between the magma and the air to provide power through a Stirling engine. It can move forward without almost any additional fuel, and the cost is much lower than transportation by road.

I don’t know where to go. It is after realizing this gap that the humans of this world built railways, which are much more difficult than roads.

After all, they need to estimate the location of the magma river and the water level height of the rivers along the river to ensure that the location of their railway construction will not be engulfed by magma. They also need to create a concrete-like structure to support it above the magma to ensure that it will not be engulfed by magma.

In order to be melted from below, it is necessary to ensure that a foundation is laid below the magma so that the pillars supporting the rails will not deform or fall during the flow of magma.

These are all epic-level projects for human civilization in this world, and they have successfully completed these epic-level projects one by one, which can be said to be quite successful for them.

A large amount of ore was transported to the ocean along this lifeline, and construction in the ocean developed in this way. Although when large machinery needs to be built in seawater, it cannot be supported on land like it is on land.

The ground and the deep sea are extremely deep. If production is carried out on the seabed, the huge pressure is normal and humans cannot bear it.

However, humans in this era also discovered some advantages of the seabed.

In the ultra-high-pressure environment under the sea, if some metals are cast, metals with a higher density than ordinary metals and a stronger internal crystal structure will be produced, and even the high-temperature resistance of these materials will be relatively improved.

At present, they have also begun to try to make some machinery to process objects in deep water. High-strength and high-pressure materials are now widely used in drill bits. And drill bits are also quite useful equipment for people in this world.

.

After all, they live underground all year round, and they must use drills to dig their own caves and tunnels in caves.

But once we got under the ice, we still couldn't escape the fate of digging holes.

Under the ice, they must use their drills to dig out a piece of the ice cap above, introduce air into this area, and then create a suspended platform suitable for their own survival under the dome.

The living pattern is actually not much different from that in underground caves. The difference is that here they do not rely on the high temperature provided by rivers along the river, but on the entire warm ocean, so the direction of the development and cave can be arbitrary.

Humans can dig in whichever direction they want according to their own plans. The biggest benefit of this is that they can regularly divide their living areas into hexagons during the digging process.

Areas. In other words, they are triangular areas. These triangular areas are regularly distributed, making every road orderly. Urban traffic is easier to handle than before when complex terrain had to be considered in underground caves.

many.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! These are the projects they have carried out near the sea. With the increase in population and the advancement of technology, the area occupied by humans is still further expanding.

Expand and move towards the depths of the ocean. This world is somewhat similar to the earth. The ocean surface is also extremely huge, occupying most of the entire planet.

The dome-like ice surface is like the continental plates on the earth. The characteristic of each plate is that it is thinner in the middle and on both sides. Human beings now only live on the edge of the plate closest to the sea. They

The current development method is to continue to develop from the edge to the center.

During these years of survival, they found that the edge of the plate is relatively fragile. Ice blocks will also collide and squeeze each other during the ocean current activity below. The edge of the ice surface close to the continent is relatively stable, because

The continent is softer than the ice surface. During the collision and extrusion process, some silt-like structures can be generated for buffering. The probability of the ice surface breaking is not high, which is equivalent to the probability of an earthquake.

Very large. But on the side close to the ocean, the edge of the ice sheet often cycles through the process of breaking and freezing. The location on that side is equivalent to the volcanic earthquake zone above the earth. If someone lives there, they will

If your base is built under the ice cap there, you will face earthquakes every three to five times, which is about the same frequency as the earthquakes on the earth. But living under the ice cap, if an earthquake occurs, the casualties will be greater than

Human beings living on the ground are much more miserable. It is very likely that all the people in an underground city will be completely buried underwater.

The frequency of disasters is not much different, but the degree of disasters is very different. Therefore, the edges of plates similar to volcanic earthquake zones in this world are absolutely unsuitable for survival. Even if there may not be an earthquake for decades, earthquakes

If it happens once, it will probably lead to ecological extinction.

To be precise, this kind of earthquake cannot be called an earthquake. It should be called an ice earthquake. In order to survive in a more stable area, humans chose to move towards the center of the ice sheet after observing earthquakes occurring on the ice in the distance.

The thin structure behind and around the middle determines that the center of the plate is quite stable. Even in a collision with other plates, the center is the least likely to break. And the difficulty of surviving there and surviving in the surroundings is actually

There's not much difference.

It is nothing more than digging an area downwards as an area to carry water. Another advantage of doing this is that there is a ground similar to that in a cave.

It may sound a bit difficult to understand. But by analogy, you can understand by digging a cave. Although the oceans in this world are covered by huge glaciers, there are still sea levels. The ice surface is basically suspended above the sea surface.

. Therefore, the sea level is located at a certain height level of the ice sheet, which is the position where the altitude is 0. Human beings live on the interface of this plane.

To survive on the edge of the ice, all you have to do is knock off the excess ice above your head, and then leave enough air above the water surface, so that you can establish a survival base where the ice is underwater.

You need to excavate the cave along the horizontal plane. After successfully completing the excavation of the cave, you can clearly find the horizontal interface inside the ice layer. Just drill a hole above the ice surface to allow air to circulate, forming

A structure like a connector can ensure that the horizontal height of all areas under the ice is the same. After knowing this, survival in the ice is actually more difficult than surviving in the water.

Easy. When the water level is the same, this is somewhat similar to building a water conservancy project on land. Digging canals guides the water in the ocean to flow to the desired location on the ice surface. At this time, there is no need to make any floats.

To create an island, you only need to dig inside the ice and dig out caves higher than the water level, which can be used as land for people to live in the ice. Those places lower than the ice are rivers and lakes, and between rivers and lakes

The center is the industrial base of mankind.

When arranging an industrial base in the ocean, it is necessary to make hollow metal boxes so that the base can float above the water. But here, the base can completely sink to the bottom of the water and take root directly on the ice surface of the bottom of the water.

, this way it is almost the same as being in a cave, except that the water here is much easier to obtain than in the cave, and the living environment is much more suitable for humans than in the cave.

When designing these cities in the ice, road traffic construction will also be taken into consideration.

Tunnels and rivers will be specially set aside for the construction of rail trains.

The water surface can play almost the same role as magma. As long as the ventilation shaft above blows enough cool wind, it can ensure that these vehicles can run almost continuously with sufficient temperature difference.

With enough energy, such cities are being developed one by one.

The icy cold wind kept blowing down from the scenery above the head, while the engineer drove a water-suspended engineering machine driven by a Stirling engine, like an excavator mounted on a speedboat on the water, and quickly arrived at the place he needed.

He dug a resting cave location, and then inserted something like a hook machine on the ice surface, cutting off huge ice blocks one after another. In order to ensure that his speedboat on the water could maintain balance, he would

Stretch out four mechanical groups to grab the underwater ice surface. These mechanical groups are made of high-temperature resistant materials developed by humans in this world. They will not melt or soften even in water and can be stably fixed.

These machines. This is not how to build giant tunnels between cities. Those are tunnel boring machines that are used to dig tunnels.

This kind of small construction machinery is more used to build residential houses and residential buildings. To be precise, it should not be residential buildings. There is no shortage of space in the world, so buildings like buildings have not been designed. Everyone

They all live on the first floor, and there is a river in the room, ensuring that each family has enough water.

The water consumption of people in this world is much greater than that of people on earth. Some people are even used to sleeping in the water because it is the only environment in which they are exposed to water and water.

When wrapped in steam, the temperature environment around you is the most comfortable for you to rest. Therefore, the beds people sleep on in this world are often connected to a pool, a diving pool connected to the flowing water. As long as you don't sleep on your stomach,

You won't choke on water while sleeping, and the role of pillows in this world is much more important than on earth. After all, if you sleep on your side without a pillow, if there is a certain fluctuation in the water surface, you may choke.

Water, this can have a considerable impact on sleep quality.
