After the tribe appeared in this cave as the traveler Chengying, the people of this tribe learned how to smelt metal. In the water environment of this world, metal smelting became a very easy thing.
The temperature of water in this world can reach thousands of degrees, enough to melt steel. At this high temperature, smelting metal and making various metal utensils is as easy as kneading plasticine.
Because water does not harm the human body, you can directly put your hands into the water to process various metal materials.
Especially if you are using tools, you can find some stones in this environment that will not melt in magma. Polish them into the shape of the required tool. This way you can cut those in the water that will not melt in the high temperature.
Softened steel. Hand accuracy is limited, but with these tools, fairly precise parts can be made from the start.
In this special environment, the cost of making steel parts is really low.
There is no problem with the human brain in this world. But after they can easily make many very precise steel structures, they gradually realize that this material is far stronger than the human body. It can make many tools, such as the simplest knife.
These steel materials will make people feel extremely cold if they are held in human hands, but there is a way to alleviate this cold feeling. For example, using wood as the wrapping material for the handle of the steel material,
Or wrap it with animal fur and keep the animal fur in a moist state. This will prevent the person holding the knife from feeling cold for a long time.
In this case, using these knives can play a considerable role in the natural environment.
Not only knives, but more tools are manufactured, such as shovels, hoes and the like.
After learning to make these tools, humans in this world also began their own farming life. Before, they only collected plants in caves as their own food and let these plants reproduce in the caves.
However, there is still a huge gap between the yields of wild crops and those grown by humans.
If crops were grown artificially, it would be enough to feed more than ten times the current population. However, the land before was too cold. The land suitable for the growth of these plants is a very cold place for humans. And if they were allowed to use their hands or
It is those simple stones. It is too difficult for them to cultivate the hard and cold ground. They can only let these plants grow in places suitable for them.
But now that we have steel tools, it's a completely different story.
You must know that this was only popularized on a large scale during the feudal era. Even in the early feudal era, the usage rate of iron tools was not very high. More things like bronze were used.
Because it is quite difficult to smelt steel. But there is no doubt that steel tools are much easier to use than bronze tools.
Especially after mastering the skillful technology of making steel materials, humans are now able to reclaim land in caves and use it to grow crops.
And the tribe in this originally small cave also began to increase in population.
They have the ability to feed more people easily. If this is the case, the number of people who can survive here will also be greatly increased.
This is a long process. Although Entropy lacks patience, he has always put his eyes on this place, and he can see the development of this tribe bit by bit.
As this tribe continues to grow and develop, the number of people is increasing. Foreign people have also integrated into this tribe. The tribe that originally had less than a hundred people now has thousands of people.
And this population size can already support some larger-scale processing industries.
Under normal circumstances, a tribe of thousands of people can't even smelt steel. At least not under a normal physical environment, because smelting metal involves not only the metal sector, but also you.
If someone wants to mine, the miners need to be out of work, and for these people, other people must produce food supplies.
And how many people produce food that can supply one more person who does not produce food determines how many people in a tribe can engage in handicrafts.
Under normal circumstances, with the level of difficulty of steel smelting technology, maintaining a handicraft population of that size would require at least a town of tens of thousands of people.
But their cost of metal smelting is too low. They only need to throw the metal into the water and squeeze mud in the water. Even children can do this kind of thing, and even some children are better than adults.
Doing better, because some children have relatively less labor experience and their hands are more delicate than adults. At least they have an advantage when performing processing that requires higher precision.
And as the population of the tribe reaches a thousand people, and with the difficulty of metal smelting being so low, it is possible to try to develop some industries.
For example, if you are making some simple machinery, something like a spinning machine, jumping to a steam engine is still a bit too much. You need to let these people understand what machinery is first, so that they can learn to become more advanced and complex step by step.
Manufacturing of machinery.
The structure of the spinning machine is relatively simple. For people in this world, it is not difficult to understand. They also have certain needs for this kind of equipment. After all, after eating, what is left
Just wearing them, clothes are very important to people in this world, because their clothes can keep warm. And in this extremely cold environment, relying on your own body temperature is more effective than relying on your own body temperature.
People are more comfortable near magma. If they live near magma, their skin will gradually dry out. To the outside world, the body temperature of the human body is actually very low, but the rules of this world are so strange. If the body temperature can always be maintained
If so, there will be no risk of harm to oneself due to the freezing of blood in the body.
In other words, as long as we wear enough warm clothes, humans can survive for a long time even if they enter an icy and snowy environment.
The weird rules of the world have caused a high demand for warm clothes in this world.
In the past, they could only use the furs of wild animals in this world that they occasionally hunted as their clothes. On the one hand, the quantity of such things was small, and on the other hand, they lacked many chemicals to process these furs and wear them.
It's very uncomfortable on the body.
Untreated leather will become quite hard after being air-dried for a long time. It is more appropriate to call it a piece of armor than clothes.
That kind of thing cannot be worn on the body for a long time. In comparison, the cost of clothes made by weaving plant fibers is lower, and they are more comfortable to wear and can also achieve the effect of keeping warm.
Therefore, things like spinning machines and textile machines have room for existence.
And humans in this world are gradually understanding what machinery is.
Under normal circumstances, these mechanical equipment are actually made of wood and the like.
You can also find some wood-like plants in caves, but their yield is not very high. In comparison, the cost of processing steel into steel pipes as a support structure for these machines is actually lower.
After having clothes, the people of this tribe can more easily travel to other tribes and travel through ice and snow areas more easily.
A large number of travelers began to be born, and they were able to reach other tribes, which meant that warm clothes could be sent to other tribes for trade.
The most basic trade product. With enough metal materials, another thing appeared, that is, a car. Although there are very few large animals in this world, there are no large animals that can be tamed to travel in the ice and snow.
Animals are used as livestock to pull carts, but even if people push carts, they can carry much more things than what can be carried in a backpack on a simple and smooth road.
For vehicles with metal structures, after humans in this world had a certain understanding of machinery, they also began to try to make springs and suspensions. Wrap a layer of gel-like stuff around the wheels of the car to reduce vibrations. After various treatments,
The car became much lighter when pushed by human power.
As a result, the volume of trade also began to increase. Now the most precious industrial products in the world are various textile machines and vehicles. If these things are transported to other tribes, they can even be exchanged for all their goods within a year.
output.
Because clothes and transportation are really necessities in this world. It is difficult to connect human beings who are isolated in different underground caves. After experiencing the life of owning these handicrafts or simple industrial products,
Some people accept their original life.
At the same time, in the process of metal smelting, humans in this world are also constantly trying to make metals that can withstand high temperatures.
This attempt is to add water during the smelting process. The water in this world is not only different in temperature from the water in the regular world, but also different in another aspect, that is, the chemical properties, under some special conditions
Under the condition, it can be integrated into the metal like an alloy. In terms of the properties of metals with water molecules inside these atoms, the strength is reduced to a certain extent, but it achieves the effect of high temperature resistance, that is, once cast
After forming, it will not melt in water.
This phenomenon can be said to be an almost revolutionary change for today's humans.
This means that, in addition to the ore they named obsidian, there is finally a tool that can be used underwater, and unlike obsidian, this tool can only change its shape simply by polishing it.
The material is resistant to high temperatures and has slightly higher strength than obsidian. It can also be made into the shape you want by casting.
After being taken out of the water, its strength is slightly lower than ordinary steel, and it can be cut and polished with tools made of steel. This means that humans can try to make simple machine tools underwater, and they do not need to be very big.
power, because in this environment, all kinds of metals are quite soft, and after the relevant materials are mass-produced,
Another technology was born among the tribes, and that was stamping.
Under normal circumstances, stamping metal at room temperature requires a lot of force and extremely high-strength materials. Under the current productivity conditions, it is theoretically impossible to achieve.
But under water, metals are in a nearly molten state, which means they are quite soft and can be easily stamped and formed.
As a result, the production of pots, pans, and other relatively simple-shaped materials has gradually increased to an incredible level.
The cost of metal vehicles, which previously required a large number of parts to be assembled, began to drop significantly, and communication between different tribes of humans became much easier.
Because of the increase in productivity, the duration of slavery in this world is quite short. Because in the production process, the importance of calculation and knowledge is gradually realized, the role that slaves can play is getting smaller and smaller, and they cannot
It is difficult for slaves who exert their subjective initiative and do not engage in in-depth study to complete this preliminary industrial production.
In addition, the cost of management and suppression is too high, and it is not as simple as the employment relationship.
It is precisely because of the development of productivity that slavery only lasted for a short period of time before entering a situation similar to the feudal system. And the current group of human beings who have just touched the threshold of industry are indeed more suitable for the feudal system.
The reason is also very simple, that is, underground caves are equivalent to city-states for humans. Although they already have warm clothes and transportation, the cost of crossing the long distance between city-states is still quite high. The central government
If you want to suppress the local area and directly govern the local area, you can only do it in a few caves that are relatively close to you. If you want to manage the remaining ones that are further away, you can basically adopt the method of enfeoffment.
Otherwise, it will be beyond our reach and there will be various rebellions everywhere, which will increase the cost of national management sharply.
To change this situation, what is undoubtedly needed is higher productivity, productivity that is enough to allow humans to survive outside the cave.
And as people have reached the threshold of public welfare, all of this has opportunities, but one problem is that the steam engine in this world may not be built.
The reason is very simple. Water is not a suitable medium in this world. It would be very difficult to boil the water in this world.
