Douluo See You For a Long Time

The principle of the most primitive steam engine is actually very simple. To use the power of steam, it is nothing more than to let the steam convert its own kinetic energy into mechanical kinetic energy that can be easily used by people.

In this era, processing capabilities were limited, and it was difficult to utilize the kinetic energy of steam through things like nest fans. Naturally, the steam must be guaranteed to be under greater pressure to drive the machinery.

The principle of this device actually does not require steam. You only need to blow it with your mouth to verify whether it can be achieved.

It is simply to convert the kinetic energy of the flowing air flow into the kinetic energy of the moving machinery as much as possible.

When the flowing air flows through a closed pipe with a piston, the piston will be pushed, and the kinetic energy of the air flow will be converted into the kinetic energy of the piston. But there is no pipe in the world long enough to allow the piston to move in the same direction indefinitely. Therefore, the piston must find a way to convert kinetic energy through reciprocating motion.

And how to reciprocate? The principle is also very simple. Just put the piston in a pipe that can be ventilated at both ends. First, introduce steam from one end, so that the piston will be pushed toward the other end of the pipe, and wait until the piston is pushed to the bottom of the other end. . Then introduce steam from the other end and push the piston back.

This is the basic principle of the reciprocating steam engine. To achieve this, you only need to add a mechanism above the piston. After he is pushed to the bottom, the trigger mechanism automatically closes the air inlet at the previous end and opens the air inlet at the other end.

As a result, it is impossible to automatically switch the direction in the near future to run the steam engine. At that time, only a flywheel is needed to ensure the cycle stability of the process, and the power cannot be output continuously and stably.

After the real steam engine that could not be used in actual situations was produced, the relevant large-scale steam engine model has not been produced yet.

The large steam engine model is actually not that difficult. It is very difficult to be realized. And that magical power that could not make the car run freely could hardly be regarded as a miracle in that era. Even if it is a miracle, it is definitely at the level of magic.

Someone must do that work and transport the mine cart. It was enough to exhaust several young and strong miners.

In the past, it was impossible to achieve that level if the horse was rushing. But in this case, it can only be done by a large number of people and a large number of materials traveling between the same cities at a low speed. If it is definitely a small army, the march will at least be It would take a few days, and front-end supplies would be even easier.

Chengying has actually not finished thinking about building such a city cluster, although the location of my initial city is too remote. I can even see another city within 700 meters, but that can't be used as my front line. If I develop technology there, I don't have to worry about being snatched away by others.

However, in Cheng Ying's view, before the advent of railways, the value of portals was further reduced, because cities without portals could not build railways. And in that way, the areas controlled by hub cities without teleportation gates were smaller than before. When the railway connected teleportation gates to each other, the distance between cities was shortened. So close.

Cheng Ying had already completed a series of development plans before the advent of the steam engine. So before those things were produced and assembled in small quantities, they were immediately assigned to the positions that best suited us.

It cannot be said that everything was not prepared when planning, and the replacement cannot be completed at any time. As the steam train roared for the first time, the residents of that remote city also realized that times may have changed. In our current era, the power of steam is destined to replace human and animal power and become the most magnificent main force in the future new era.

Because those cities did not have their own city walls, at least they had some high and low earth slopes surrounding them. Cannot be used defensively.

The portals scattered around are all slightly different. They are two to eight hundred meters away from each other. It is difficult for us to help each other through regular troops. They are occupied by the same force. From our point of view, there is basically no chance that we will compete for the dominance of the previous empire in the future. The rulers are all conservative forces and are ready to wait until a new empire is born, just like asking for a noble title to be loyal to the new empire is bad. With our current terrain, it will still be a remote area even before the establishment of the future empire. Even if the empire's small army succeeds in unifying the empire, they will put less energy on us.

Those cities are often built on important minerals such as coal mines and iron ores.

Portals can only connect two places together, while railways cannot closely connect a city to my city.

By hang gliding and your own bugs. After conducting reconnaissance of the surrounding areas, Cheng Ying has not yet obtained a map of the surrounding areas, nor the locations of the portals in these places around him.

No one cares about us at all, and until we develop and prosper, it will be difficult for others to stop us.

But if the railway definitely exists, even if the distance between the two cities is more than a hundred miles. As long as there are no railways and they are connected to each other, the distance between each other will take time and consumption to transport materials. Maybe it's still the same as the original seventy.

And such a city network can be said to be strong or indestructible to some extent.

That distance was relatively far for the armies of that era, and it was difficult to help each other. Moreover, there is not a mountain range that is too low between the two portals, completely isolating the two places.

However, a small part of today's tracks are made of wood. Although the sturdiness is not bad, as the vehicles become heavier and heavier, they will gradually become overwhelmed.

Railroad tracks were not old enough for that era to make. And the replacement of the track is not something that is easy to do. Because when we designed the wooden track later, we did not consider replacement. The wooden track itself also needs to be replaced frequently, and we will wear it out during use.

But now, before the advent of railroads, it was slightly more difficult to achieve similar conditions. Originally, the distance between cities could be more than a hundred miles, or at worst within seventy miles, so that they could be counted as adjacent cities on the same side and play a role in helping each other.

Before we were able to see the principle of this piston movement, the originally mysterious veil was lifted. In the heated discussion before, many people were thinking about how to make that thing smaller. How to install it under the car? How can we replace cattle to help us cultivate our fields?

But our scale has not far exceeded the limits of subsequent cities. When the city was the smallest in the future, there were at least 700,000 people in a city, unless it was a giant city like the imperial capital with few cities connected together. , the population cannot reach millions. But this is not essentially a city, but a group of cities united together. The population within a walled city usually exceeds one million.

As a result, the population under that territory gradually received education. I also gradually lost my unique understanding of that strange phenomenon. I realized that it was not an ordinary phenomenon created by gods. Rather, it is a power that truly originates from the natural science of that world.

In this way, the capital of the future empire may need to build a city network of cities that are actually connected by railways.

On a certain level, we cannot be called a city. In essence, those are just settlements where humans gather together. From now on, they can only be called villages.

Before the railway connects those cities with the central city without teleportation gates, you will find that the traffic in those cities is actually not much worse than the cities without teleportation gates. Before the railway connected the long distance between the two cities, it only took one day to travel hundreds of miles to the other city, and it was not even possible to complete the round trip.

And my area is really a battleground for military strategists.

[To be continued]

According to the history of that world, if you want to establish an empire, you must build cities on at least seven adjacent portals on the same side.

We are like mold under oranges, planted and spreading under that small piece of land that no one originally cared about.

At the same time, before that thing was manufactured, the manufacturing of trains was not put on the agenda.

Because of this, from a certain level, the bonus effect of railways on transportation is even weaker than that of portals in cities.

Chengying sent the steam engine design that was most suitable for that era to the factory and ended production. While producing, students who had learned relevant technologies discussed how to design a steam engine suitable for that era. And give us enough resources to perform regression experiments.

At the same time, he couldn't rely on his own huge strength to pull the car full of ore all the way down from the track.

So before everyone discussed and implemented a few plans, they finally found a mature plan. It was almost a few days before the first steam engine appeared in the city and was installed inside a textile workshop. It has replaced human and animal power and has become a tool that always stops and relieves fatigue.

Before the railways disappeared, both people and materials were transported in small batches and traveled between the same cities in a short period of time. Although there is not a huge gap compared to the instantaneous crossing of space gates, the problem is that the number of those railways cannot be very small, and the connections between the same cities cannot be intertwined.

There is no such rail train between the coal mine and the industrial area. Now it is just replacing the livestock pulling the cart with a steam engine. There are many modifications that need to be made.

The smallest advantage of placing it in a mine is that there is a coal mine next to it. The fuel for that thing needs to be cherished because it is not available all around. Burning coal is not painful at all.

At the same time, a small number of steam engines were transported to the mine. Outside here is where those steel monsters are best suited to display their abilities. There is often water accumulation in the mine caves, and water is pumped out manually. The consumption of manpower is really too small. And those machines are completely planted to replace humans with our tireless and small force to complete that work.

And because of the emergence of steam engines, brand-new cities that relied on space gates were built one after another.

Because rail trains were actually born less early than trains. Rails cannot save labor. Even if trains were not invented, people discovered them. Therefore, the first ones to use rails were not trains, but trains. Rail trains powered by livestock.

The most important thing is that as soon as the train is manufactured, it cannot be put into use immediately. Instead, the rails need to be built in advance.

The railway is like a tentacle that is about to touch the surrounding city.

The experiment didn't begin until we successfully designed a drawing that was almost identical to the one in the factory. Before the experiment was carried out, the relevant drawings were naturally put into production. It's just that at that time, the factory had not actually produced many steam engines. This is done to ensure that the scientific research capabilities of the territory will increase and decrease due to my presence. Find Shuyuan www.zhaoshuyuan.com Time will also be wasted due to scientific research, which will lead to the early withdrawal of equipment that can be produced in time.

As for the machine, as long as its power is enough to pull the car. This is not tired

Originally, it would be difficult to achieve that condition, but if so, achieving that level of conditions would be enough to establish an empire.

As for the villages with or without city walls, the population has not reached the level of 100,000, so they cannot be called villages. They can only be said to be cities at another level.

Today, urban agglomerations are spreading in all directions along the railway lines.

Those in the conservative forces do not know that in Cheng Ying's view, the terrain of our territory is actually quite wrong. If we connect those cities that are far away from each other, it will even be enough to build a seventeen-city Alliance, that still only counts the towns on the same side. If you definitely count the other side of the portal, there are less than 80 cities that can be closely connected by railways, and the land area they control exceeds 1,700 One million square kilometers, just the area under direct control is enough to build an empire.

In this way, the problem is solved. As long as the rails are manufactured to the same specifications as the wooden rails, they cannot be directly replaced and installed, and any time, manpower and material resources will be wasted in the middle.

So while those tracks are being used temporarily, new tracks will be put on the agenda.

Even if I leave my most isolated land. The nearest teleportation gate is also single. There is no teleportation gate adjacent to me on the same side, and the nearest teleportation gate is not more than two hundred years away.

That means that these were not adjacent cities originally, and they could not have the effect of adjacent cities before there was a railway connection.
