And these small tribes, even if the population cultivated out of production is only a few hundred, with such a small number of people, there is no way to inherit any difficult knowledge, a large amount of knowledge has been gradually forgotten in the long river of time, so although in more than a month, almost more than 60,000 people have been recruited, but these people all only have the production and manufacturing capacity of the most elementary agricultural society, and they have very limited knowledge of more advanced science and technology.

This made Shu Han and Liu Sanyi very disappointed, but it is better to have these people than nothing, at least through them, more people can be removed from production, so that more people can leave the countryside and enter the city, and learn the knowledge left over from the pastoral era, which is undoubtedly a good thing for Yi Kuiluo.

However, the speed of the talents obtained by education is too slow, and there is no substantial benefit to the existing technology system of Black Iron City, which makes Liu Sanyi and Shu Han more anxious, but since people can't find it, let's see if there are any books that can be preserved, at least it can enrich the libraries of various cities.

In the end, I did find a little, but unfortunately these tribes, even people's lives are very difficult, let alone how to preserve these books, the inheritance of knowledge, not everyone is so respectful, in this case, the preservation of books has also become very difficult, so they get not many books, but very few, only a few hundred in total.

Because further west are already hilly areas, the terrain in these places is broken at the same time, the biogas is relatively heavy, the preservation of paper books is very difficult, there is no ability to preserve for a long time, so most of the books are damp, there are many traces of insect moth, which is a trouble for today's Black Iron City.

And Liu Sanyi did not give up looking for a big city, after all, the entire west is very unfamiliar to Black Iron City, and people don't know much about it, and it is precisely because of this that the speed of searching is also very slow, and there are still a large number of fierce beasts on the way, which makes their speed not fast at all.

Shu Han is concerned about Liu Sanyi's progress on the one hand, and on the other hand, he is also distributing the new city residents, Liu Sanyi found more than 60,000 people from the west, and Huajin City naturally got more than 10,000 people, which made it possible for Shu Han to build a second power station and expand the current coal factory at the same time, and on the other side, Black Iron City and Asakusa City also began to build their own power stations with the help of Dürxin.

Today's Du Erxin can be said to be a busy man, the success of the Huajin City power station, let people see that the era of civilization is not far from them, which makes them very excited, after all, many of them have read the articles of the pastoral era, know that in that era, people's lives are inseparable from a thing called electricity, they can make the night like day, can make the machine run on its own, can make everyone even if they are thousands of miles away can communicate with each other, that era there is also a thing called the Internet, They can connect everyone to a virtual world, and these things that are written in words, although people have not seen them, know that they are things that only existed in the age of madrigals.

More than 300 years have passed, and the once beautiful era of mankind is now gone, which has made many people have taken the stories in the books as legends and stories, and now, the lights of Joaquin City have begun to revive the memory of that trace of ancient reminiscence, so that the cities of the Black Iron City now want to build power stations, so that their cities can be bathed in the lights of civilization again.

But it's a pity, now the power station is not difficult to build, but the job of digging coal is really very difficult, in the absence of truck transportation, relying on manpower alone, it is really a very difficult thing to transport a large number of coal mines, which also makes people have a thirst for larger transportation equipment, so in this time of 60,000 people, Liu Sanyi specially allocated 20,000 successful railway workers, the main task is to build a railway connecting the coal mine between Huajin City and Black Iron City, a total of more than 150 kilometers, It will take about four years, and now Liu Sanyi hopes to invest 30,000 manpower, which must be completed within a year, and stable production must be achieved within half a year.

This is undoubtedly a very complex task, the difficulty factor is also very high, although now the Black Iron City has begun to build the railway between Zitong and Huajin City, the experience of the railway is relatively not as ignorant as at the beginning, but at the same time, the railway repair is not the whole task, but also to connect the coal mine transportation system and the railway system to ensure that the coal that was blown up by the bomb can be transported to the carriages as soon as possible, so that it can be transported as soon as possible to transport the coal to the power station.

Of course, there was also a discussion in Black Iron City, that is, it is not good to simply build the power station next to the coal mine, and generate electricity here and there. But unfortunately, Shu Han had already thought about this trick at the beginning, but due to reality, he could only give up in the end.

First of all, a problem is that it is too far from the coal mine to Joajin City or Black Iron City, if you build a power station, then you will need to pull a long wire, which requires telephone poles, and also needs a large amount of copper and iron raw materials, and now the production capacity of Black Iron City is very low, and it is impossible to produce so much.

The second point is more important, that is, the population of the Black Iron City is too small, and the technology is relatively backward, like most of the modern wires will be hung on the tower, the main reason is to prevent the wires in the wild from being bitten by those animals, resulting in leakage, in order to affect the development of the city and electricity, the power station will be repaired very high, so as to ensure the safety of the wires. 33

But in this era, the tower can't be built so high, at most it is about twenty meters from the ground, such a little distance is nothing, some cats can climb up completely, there will be no problems, the second is that the birds of this era are very fierce, they can completely bite off those wires, and the population of the Black Iron City is too small, it is impossible to protect the entire wire, there will inevitably be a large number of no man's land, which will cause a lot of damage and accidents, and there will be a lot of problems with power supply.

Therefore, in the end, the power station can only be built close to the city, so it is easier to control, unlike around the coal mine, it is too difficult to repair and maintain, so it is undoubtedly better to build a railway, first of all, it is to build a railway, which is safer than the tower, and secondly, it is more convenient to transport, the most important thing is that the technical problems are relatively easy.

In the past three months, under the guidance of Shu Han and the help of Black Iron City, the railway between Zitong and Huajin City has completed the road cleaning and began to lay the railway, which naturally encountered many difficulties, such as how much width between the rails, and then the design of the locomotive, how to stuff a steam engine into it, and how many carriages a train can drag at the same time, How to operate can be more time-saving and labor-saving, etc., these are all questions that need to be considered, and every step must not be wrong, and needs to be considered as much as possible.

At the same time, how to ensure the safety of these rails in the wild, you must know that although these wild rails are very heavy, ordinary animals can not move at all, but at the same time, there will be some animals walking in the middle of the railway, when the train passes, directly crushed, there will be a big problem for the train to run, especially if it is an elephant, giraffe and other animals, the size is too large, if it is directly blocked at the intersection, then there will be a very huge problem for the train to run, these naturally need to be solved, and in these aspects, Huajin City has indeed accumulated some experience, but there are also many difficulties that have not been encountered before on the railway from Zitong to Huajin City and from Huajin City to the Black Iron City through the coal mine.

After all, the road from Zitong to Huajin City is only 60 kilometers, which is not too long, and now the one that Liu Sanyi wants to build is about 200 kilometers, and the straight-line distance is 150 kilometers, which shows that the construction is very difficult, and the whole railway needs to be rounded I don't know how many bends, it is impossible to build as easy as the railway from Zitong to Huajin City, and because of this, this is undoubtedly a very huge challenge, but for today's Black Iron City, this is exactly what they need.

With the increase of population, increase the industrial population, reduce the agricultural population, this is a necessary step, and if you rely solely on the market, with the market of 600,000 people today, it is obviously not possible, only rely on the help of other aspects, can be done, one of them is to build a railway, so that you can quickly train a large number of railway workers through this railway, and at the same time there are train workers, smelting, engineering and other supporting industries for rapid development, which is to concentrate on doing great things, As long as it can be done well, it will be decisive for the industrial development of Black Iron City.

It is precisely because of this that Liu Sanyi will sit down and make such a bold decision, just like Shu Han noticed the crisis of the Black Iron City, Liu Sanyi could not have noticed that the Holy Alliance was also developing during this period of time, and their size, as long as it developed, would inevitably cause a very unfavorable scene to the Black Iron City, so Liu Sanyi's heart was also very nervous, because of this, he would pay so much attention to the industry, that is, he hoped that electricity could be popularized as soon as possible, so that the production of the Black Iron City could be put on a new track.

At the same time, the search team sent to the west finally came with good news, and found a city-state about 140 kilometers away from Black Iron City in the west, with about 200,000 people in number, and more than 60 villages at the same time, and the whole city retained the scale of the first industrial era, which made Liu Sanyi very excited, and immediately prepared to support the army to attack the city.

Shu Han originally only had to oppose this, to see if he could cooperate through cooperation, or alliance, so that the two sides could cooperate, but in the end he gave up this idea, first of all, the strength difference between the two sides is too much, now the Black Iron City has a population of nearly 700,000, compared to this city, the population is about three times, the strength of the two sides is completely unequal, the Black Iron City is already in the early stage of the second industrial revolution, and that city, according to the investigators, It should be barely retained in the era of industrial civilization, and it is still much behind compared to the Black Iron City.

Black Iron City wants to defeat the other party, it is not a difficult thing, another point is that there is not so much time in Black Iron City now, if you want to peacefully unify the two sides, the communication between the two sides will be a very long process, the other party is used to independence, at this time suddenly said that you want to include yourself in the other party's rule is naturally unwilling, as for the alliance, why do you want to form an alliance suddenly?

The two sides want to explain and trust each other, which will take at least a few months, so that each other can increase their understanding, and at the same time let each other know what this world is like, and now Black Iron City obviously does not have that time, they want speed, the competition with the Holy Alliance itself is a race against speed, what they lack most now is time, so the choice is naturally the least time-consuming method, that is, war, as long as it is obtained, victory, everything on the other side is their own.

But at the same time, Liu Sanyi also paid great attention to it, after all, it was to receive the other party's property and population, and it was not as simple as killing all the people, so in the process of occupation, Liu Sanyi's way was to reduce casualties as much as possible, and then salute before the soldiers, and first tell the other party how bad the situation is. Throwing the responsibility on the heads of the leaders of that city, you can blame them for negligence, and finally let things become like this, which can make the people of that city have less hatred for the Black Iron City, so that they can better integrate into the Black Iron City, Liu Sanyi is not particularly worried about this, he firmly believes that this battle will end in a short time, and the combat effectiveness of the two sides is not at the same level at all, and what needs to be done now is to build a road while negotiating, and wait for the road to be completed, It will be enough to lead the army directly forward.

On the other side, when Shu Han received the news, he was supervising the construction of the second power station, which is an area that Shu Han attaches more importance to, hearing that there are more than 200,000 people, and there is a city, he is really happy, the city represents civilization, as well as the technology behind it, knowledge, which is urgently needed in today's Black Iron City, so Shu Han wrote to Liu Sanyi, hoping that he can protect those libraries, educational facilities, etc., and not cause too much harm to civilians.
