And through the high-precision three-cutter wheel machine tool, the industrial level of the Black Iron City has also improved a lot, the original some bearings, drive levers, gears, etc., have been greatly improved in accuracy, which undoubtedly has a huge effect on industrialization, such as gears, if the accuracy is relatively low, then the number of gear sets can not be more, because in the case of low precision, if the number of gears is too much, there will be a jam.

And the higher the precision, the more the number of gear sets can be arranged, which is why good watches are so expensive, not just because of the name of luxury, or because they are indeed a peak of the mechanical industry era, and many of these gears are handmade, in this case, a watch, hidden more than 100 gears, this kind of technology, is indeed called the pinnacle.

But compared with the industrial machine tool, it is obviously a lot inferior, under the modern industrial system, people who do not understand if they see the machine tool working for the first time, they will even think that this is the subject of science fiction films, but in fact, like what we can see in our daily life today, everywhere is full of this kind of scientific and technological content that is difficult for ordinary people to understand.

Just like now there are more than a million transistors hidden in a chip, and his area is only the size of a fingernail, this is the pinnacle of human industrial technology, compared to this, no matter how good the ancient craftsmen are, it is impossible to achieve such a point.

Through these machine tools to process parts, on the one hand, the pressure on the workers is reduced a lot, and the progress of the project is accelerated a lot, and at the same time, these parts have also promoted the birth of a large number of industrial tools in the pastoral era, such as welding guns, protective covers, and rammers, etc., have begun to be used on a large scale, including the transformation of steam engines and generators, which have great effects, not only to improve the capacity and speed of trains, but also to improve the efficiency of the use of coal in power stations.

At the beginning of human research on the power station, the ratio of coal energy to power generation was almost 7.5 percent, that is, only 7.5 percent of a ton of coal was used to generate electricity, and the remaining energy was all wasted, which was undoubtedly a huge waste, although compared with the steam engine era, the utilization rate of less than 5 percent was much better, you must know that even in modern times, under the premise of such advanced science and technology, the utilization rate of coal power generation is only about 70 percent, because coal is heated by water. Then the thrust of water vapor is used to drive the power generation group to generate electricity, in the middle, the water has to absorb energy, and the surrounding facilities and equipment will also absorb energy, and in the process of energy conversion, a part of the energy will naturally be consumed, so 75 percent, which is almost the largest value of human beings using coal to convert into electricity.

In comparison, the power station of the Black Iron City is obviously much behind, the main reason is the level of science and technology, because of the low industrial capacity, so the parts made are often stupid and black, which makes the need for a closed machine, the sealing performance can not be fully mastered, and there is the internal steel pipe sheet, too thick and heavy, resulting in very poor thermal conductivity, like many modern thermal conductive materials, often only a few nanometers or so thin, especially the nuclear power plant steel pipes, is even thinner like cicada wings, This is why the heat is transferred to the water as much as possible, which causes it to boil and then evaporate.

After all, it is really difficult to make a steel pipe only a few nanometers thin by hand processing, which still requires the use of high-precision machine tools, and at the same time there is progress in materials science, which is a very difficult discipline to move forward quickly.

After all, modern materials science is not just a simple steel and copper, it needs to add a lot of rare elements to be formed, and the distribution ratio is also to be tried thousands of times, even if the Black Iron City has the data of these metal materials, but how to match the raw materials according to the above percentages, with the industrial technology of the Black Iron City can not do it at all, and the same is true for the temperature of metal materials.

Different materials need different temperatures to be able to match each other, which requires a lot of time to arrange, so in this regard, Shu Han naturally has no way, and it is impossible for anyone to do it in the entire Black Iron City, in modern times, the things that need to be used to run such a material factory are far from so simple, so now it is the limit that the machine tool can achieve by controlling these heat steel pipes between seven or eight millimeters, but even so, it is enough to increase the efficiency of the power station by a few percentage points, Don't underestimate these percentage points, which can make the use of coal even higher.

Although a railway has been built from the coal mine to Joajin City, which can ensure the transportation of the railway, and you can obtain a steady stream of coal mines, the coal mines that can be transported by this railway every day are limited, because the number of mining workers is limited, and there is no modern machinery, in most cases, it is necessary to rely on workers to manually pick up these coals from the ground and then put them on the conveyor belt, so that the number of coal mines obtained every day is actually very limited, and there are only four or five train cars.

Because of this, even if the power station is built more, but there is no coal is also in vain, which also makes the industrial development of Huajin City can not rise one step further, which is a huge problem, so in this regard, if you can use these coals to a greater extent, so that their energy does not disappear out of thin air and waste in vain, this operation is undoubtedly the best, which can make it impossible to increase the amount of coal, get more electricity, so that the entire industry of Huajin City can rise to a higher level.

It can be said that the emergence of new machine tools is epoch-making for the entire Black Iron City, which makes the industrial capacity of the Black Iron City one step ahead of other city-states and reaches a more advanced level, which is naturally a good thing for the foreign trade exports of the Black Iron City, especially for the Holy Alliance.

Because the Holy Alliance has a gold mine in the place under its jurisdiction, which is the hard currency of the apocalyptic era, through trade, a steady stream of gold flows into the territory of the Black Iron City, of course, the Holy Alliance has also benefited, a large amount of gold can be exchanged for huge benefits for them, and the inflow of a large amount of gold and silver in the Black Iron City has made the people's lives much better, first of all, in daily life, the number of people wearing gold and silver is increasing, and it is difficult to find a few gold jewelry on people before, but now, it is often appearing, This is undoubtedly a change.

On the other hand, for the replacement of other resources, compared to the scarcity of resources in Black Iron City, the premises of the Holy Alliance and Guangyuan Kingdom obviously have more resources, but it is a pity, because all three are located in Jiangsu, Zhejiang and Shanghai, so there is no oil on any side, although Shu Han has always believed that oil should exist.

Because this place, the modern population is very prosperous, and after the cataclysm, the population of this area has dropped to less than one percent, and almost all the remaining people have died in the disaster, and Xia Shuhan in the junior high school knows that coal comes from dead plants, and oil comes from dead animals, so many humans die in disasters, and there are more animals that cannot escape doom in disasters, so many years of accumulation, it stands to reason that there should be oil.

Although according to the textbooks, it often takes thousands of years to change from animals to oil, but after all, this earth has become very strange, even what fierce beasts, demonic beasts have appeared, and the speed of material corruption is also very fast compared to modern times, how can there be oil, but it has never been, it seems that in this aspect, the earth has not changed his natural physical laws, which also makes Shu Han extremely frustrated.

After all, China's land is itself a lack of oil, even if there is oil, most of it is in the northeast, the northwest region, from the Black Iron City is too far away, the only place close to the sea, is the sea, whether it is the Yellow Sea, or the East China Sea, or the South China Sea, have been proven a large amount of oil, and from the Black Iron City is very close, the address of the Black Iron City is only more than 200 kilometers away from the sea, and less than 300 kilometers to the sea, there was once an oil field, but unfortunately, now the geography and climate have changedThe danger level in the sea is much higher than on land, so the Black Iron City did not dare to try at all and sent ships into the depths of the ocean.

Of course, the most critical thing is that there is no technology, marine exploration and oil production, can be thousands of times more difficult than on land, it is definitely not that simple things, after all, the previous buildings have long been wiped out with time, sea water is not land, its corrosion ability is strong, far stronger than other places, if there is no one to manage, I am afraid it will not take a few years, the entire oil production equipment will be completely collapsed, unusable, and now, is a vast sea, and the topography of the seabed has been completely different from modern times.

And even if it is the same, it is useless, because Black Iron City does not have a topographic map of the nearby sea area at all, this kind of drawing itself can only be mastered by special departments, and the number of prints itself is very small, most of them are in the computer, ordinary departments and ordinary people will not have it at all, and it is naturally impossible for Black Iron City to grasp things that belong to the level of military secrets.

In the absence of nautical charts, how difficult it is to find oil again on the vast sea, they have no sonar in their hands, let alone the ability to dig hundreds of meters into the ground, and at the same time, the number of demonic beasts and fierce beasts in the ocean is more than ten times that of the land, what should they do in the face of those demonic beasts?

In addition, it is the ocean-going ships, most of the ships in the Black Iron City are still wooden ships, although the Black Iron City has always planned to build an ironclad ship, after all, the Black Iron City has also mastered the use of the steam engine, and it is not difficult to build an ironclad ship, but because the Black Iron City is now putting all its energy into infrastructure construction, there are no craftsmen who can build an ironclad ship, and if there is, its tonnage cannot be too high, and it is impossible to build an offshore drilling platform with today's capabilities.

Because of this, the possibility of obtaining oil by sea in the last ten years must be zero, which is why Shu Han has always felt that it is best to unify the three kingdoms, and the strength of the three kingdoms can reach about eight million, which can completely develop larger-scale technology, so that many technologies can be rejuvenated, and at the same time, there is enough manpower to build larger ships to obtain oil.

As long as the most important materials under this modern industrial system are obtained, then the speed of human development will completely enter the fast lane, after all, the acquisition of oil, equivalent to the peak of the second industrial revolution, at that time, human beings will have greater power, but also can open up more places, so as to include more people, only a huge population can adhere to its strong civilization, this is inevitable.

But helplessly, the entanglement between emotions and the distribution of interests are destined to make Shu Han's thoughts simple, and no one will agree, and it is precisely because of this that what Shu Han can do is to try to improve the scientific and technological level of Black Iron City without oil, prepare for the future war, and let Black Iron City win this war.

After all, Shu Han is not a virgin, if he can, of course, he hopes that the three parties can cooperate peacefully, but if this can't be done, then he can only let his side win, after all, he already has a lot on this side, there are friends, brothers, wives and children, and hard-won status, now let him help others, maybe he can get a good answer faster, but for himself, emotionally unacceptable, At the same time, he couldn't believe that the Holy Alliance and the Guangyuan Congress trusted him as much as Black Iron City, so all Shu Han could do was to help Black Iron City get through this difficult time as much as possible.

The invention of machine tools has accelerated the industrial process of the Black Iron City, and the birth of a variety of equipment has also accelerated the construction of the railway in the Black Iron City, although the number is still only more than 4,000 people, but the progress of the work is indeed a lot happier, in just half a year, it has laid about 60 kilometers of railway, although in modern times, this number is not eye-catching, but in the forest can do this number, it is not a simple thing, and Shu Han will also engineer the troops from the original two groups of atmosphere five groups, It was not possible to carry out construction in different places before, because the equipment was limited, and the transportation capacity was also limited, so it was impossible to build it apart, and it could only be built from the two ends of the Black Iron City and Joajin City, so that the materials could be transported in time.
