For Shu Han's approach, most people are very agreeable, after all, people themselves have the aesthetics of life, no one wants to live in a dirty place, but there are also people who are puzzled by what Shu Han did, after all, this world is not luxurious enough to spend so many resources to build the city beautifully, all in all, although many people like Shu Han's approach, but there are also many people who express opinions, but in any case, living in such a beautiful environment, The mood of the people is indeed much more relaxed, and if you ignore the huge wall about 30 meters high, then this small town is almost no different from those small towns in modern Europe.

As a flat city, although it is on a high ground, but unlike Yeyu City, there is no geographical advantage as protection, so it is natural to need a city wall to protect the safety of the city, and in the era of reinforced concrete, the construction of the city wall is undoubtedly more convenient than in ancient times, and the height of the city wall is also very scary, like the city wall of the black iron city was built three hundred years ago, and the people at that time still retain a lot of knowledge about modern times, so the city wall directly reaches about seventy-five meters, and it stands on the ground and looks at the past, there will be a sense of shock, Because of this, many people in the Black Iron City believe that the wall was given to them by a certain god, that it is a creation of God, and so on.

This can also be understood, why did ancient Europe build so many towering churches, is because tall buildings can give people a visual shock all the time, so that through guidance, it can become a spiritual shock, those Christian churches will almost all build a very high and wide roof inside, so as to ensure that people are in the church, can only feel their own insignificance, this architectural style, is to highlight the high of God, the insignificance of people, high walls also have this effect, In the case of the loss of human technology, it is understandable to worship a wall.

Now it is naturally impossible for Joaquin City to build such a tall city wall, firstly, there is no technology, and secondly, there is not enough manpower, so the engineers gave Shu Han the advice to build a thirty-meter-high wall to separate Joaquin City from other surrounding areas, which Shu Han supports, at the same time, the defense of Joaquin City cannot completely rely on the city wall, just like the defense of aircraft carriers does not rely on the aircraft carrier itself, the surrounding frigates, destroyers, submarines on the bottom of the sea, and planes in the sky, Together, these form the defense system of an aircraft carrier, and the same is true for a city.

As a plain, each mountain pass has to be rushed, so it is natural to build forts to ensure the safety of the headquarters of Joaquin City, and at the same time, at some commanding heights, lookouts should be built to monitor and reconnoiter distant places, so as to ensure that when the enemy appears in front of him, Joaquin City still has time to deal with it, and at the same time build new roads around the city and the countryside to ensure the smoothness between each other, these are the most basic, and a city must have in this era.

At the same time, it is almost summer now, according to the weather in the area, it is already very hot, but farming cannot be stopped, otherwise the food problem will soon affect the development of Huajin City, so Zhang Song and others are almost not in Huajin City these days, but in the surrounding villages, to investigate the local development, because these lands have not been planted for a long time, plus most of the farmers in Huajin City are tribesmen from various places, they are sparsely populated, so there is very little scientific and technological inheritance for their ancestors, There are also some descendants of city dwellers, who don't know how to farm at all, and only know how to sprinkle seeds in the ground, as for how to take care of these rice seeds, they don't know at all.

This takes time, and the land is cultivated for the first time, and it also takes time to make the land more fertile, these tasks are very trivial and complicated, Zhang Song and others are also too busy to touch the ground, but even so, there is still a lot of work, for this reason, Shu Han specially asked Lin Bida to take the army, simply no longer perform other tasks, but to the field to help the farmers dig ditches, plant seedlings, and establish a water conservancy system to ensure that the autumn grain can be sown on time, so as to ensure that the follow-up food problems can be solved.

And in the city, the major factories are also set up according to the existing pace, from the musket factory, to the smelter, to the blacksmith shop, etc., almost all the factories in the Black Iron City have moved over, among which Zhang Ruoming has undoubtedly made a great effort, of course, the other families are also cunning rabbit three holes, no one can guarantee that the Black Iron City is foolproof, if you can leave a back road, it is naturally a good thing.

This whole year, because of the withdrawal of the Holy Alliance, the development of Black Iron City can be said to be relatively stable, including Black Iron City, Zitong, Rongcheng and Yeyu City, etc., are all developing step by step, and at the same time, after Shu Han announced the restoration of the traditional system in Huajin City, Yeyu City, Zitong and Rongcheng have followed up, and the number of outsiders in these cities is generally relatively large, and the traditional system is still relatively acceptable, so they have followed up one by one after Huajin City. At this time, only the Black Iron City was left to follow the footsteps to change, but in the Black Iron City, the storm of change has begun to brew, and it will only take a while, and it will inevitably take the necessary changes.

During this period of time, because of the bumper harvest of food and the improvement of material conditions, the fertility rate of various cities has been increased, especially the infant parenting rules jointly compiled by Zhao Qingtian and Fu Erdong, so that many parents when taking care of their children, the mortality rate of children has greatly decreased in Black Iron City, the mortality rate of infants and young children is very high, because of the decline in medical standards, and at the same time, a large number of children born to men and women with the same gene sequence are often weaker for various reasons, and even disabled.

And now, the Black Iron City continues to introduce people from various places, so that the people of the Black Iron City and people in different places intermarry, so as to kill and reduce the marriage between people with the same genetic sequence, which makes the health rate of children begin to increase, and the number of disabled children begins to decrease, which first of all makes the survival rate of children greatly improved, on the other hand, in the care of children, Zhao Qingtian and Fu Erdong plus Lan Xin, combined with their own experience and understanding of medical textbooks, The children's lives and health problems are described in great detail, and Shu Han also has a pediatric department in the hospital in Joajin City to take care of children's illnesses to ensure that every child survives.

This makes the child's survival probability higher, and at the same time every child born can be raised by himself, the original birth of a child is to complete the government's indicators, born to the city, so each family only has one, will not have more, because no matter how many you have, these children have nothing to do with you, and now, the children born can be raised by themselves, and at the same time the material conditions are abundant, the Black Iron City has expanded from the original thousands of square kilometers of living environment to the current land range of twenty or thirty thousand square kilometers, This made the material conditions of Black Iron City take a leap, the material conditions and spiritual conditions were mutually satisfied, and the baby boom naturally came.

This year, the population of 500,000 people in the Black Iron City, the birth of more than 60,000 babies, this is already a very terrifying number, you must know that in the modern society, the land of China, 1.4 billion people, a year born of only 17 million babies, this number in East Asian countries is already very much, and compared with Japan, with a population of 120 million, the number of babies born every year is 860,000, and now the Black Iron City with the number of 500,000 people, born more than 50,000 people, I have to say it's a miracle. 126 Chinese Net

And in this year, there are three Skywalkers who have been awakened, aged between eleven and thirteen years old, one of the three children is in Joaquin City, Shu Han ordered, directly return the child to their parents, which makes the child's parents very happy, originally they were just an ordinary family in Joaquin City, as the work of ordinary office workers, and the mother is a female worker, working in a factory, and now a Skywalker suddenly appeared in the family, both life and social status have been unprecedentedly improved, which is naturally a great help.

The other two were born in Black Iron City, and the parenting relationship around them has become the key to the problem, because Black Iron City is still a parenting system, so these two children should be handed over to the family according to reason, but now under the Black Iron City system, the remaining four cities have been changed to the traditional system, so the children themselves are also affected, they hope to return to their parents' families, and ordinary people don't know who the parents of these two children are. Therefore, they also support the return of the children to their real biological parents, because in this way, everyone will have the opportunity to become the parents of both children.

A movement on institutional change was launched in the Black Iron City, for all this, the other four cities are naturally very concerned, after all, the Black Iron City, as the most populous and geographically important city among the five cities, also has the most resources, and the decisions made here will eventually affect the other cities, which cannot be ignored by others.

And in this movement, the people of Black Iron City and the families are undoubtedly very opposed, although the families also want to restore the traditional system, but in the face of the two Skywalkers, they naturally want to swallow them, at least most of them think so, the limitations of their thoughts make their ideas framed in a limited range and difficult to change.

Of course, more important is the issue of interests, you must know that before the appearance of these two children, the attitude of the people of Black Iron City and the family towards the traditional system was diametrically opposed, at that time, the family wanted to restore the traditional system and inherit the family inheritance to their own children, while the ordinary people wanted to maintain the current system, because this system is very stable, their work can be done from life to death, and their children can take over their own classes, life is very comfortable, and no special effort is required, Just work hard.

And now, the minds of both sides have been completely changed, which is undoubtedly because of interests, becoming the parents of Skywalkers, this is an unbearable temptation, as long as there is a Skywalker among their children, then their family's status in society will be completely changed, and they will move out of the slums to live in high-end commercial areas, and become a human being, this kind of thing, naturally everyone wants to do.

It is precisely because of this that the baby boom in Black Iron City has also detonated, many parents hope that there will be a Skywalker among their children, so that their lives and future will be guaranteed, and it is precisely because of this belief that parents will have so many children, resulting in a shortage of workers in Black Iron City in the short term.

Because many women have been giving birth to children at home, they have little free time, at a rate of one a year, to contribute to the development of the Black Iron City, there is not much time to work, half a year is waiting for the birth of the child and the recuperation of the body, in this case, the population of the Black Iron City will increase so rapidly.

And in this regard, Shu Han and other high-level leaders are naturally happy to see it, he has always thought that the population of the entire Black Iron City is too small, only more than 300,000, and even a basic social structure cannot be formed, you must know that in modern times, even a small city, has a population of millions, let alone a country, if you want to restore the prosperity of the industrial age, technology, science and technology are indispensable, and the population is even more so, without enough population, it is impossible for industry to develop, so of course he hopes that the population of Black Iron City can be as much as possible, Nowadays, it is very difficult to grab the population from the outside, and the land around Joaquin City has been searched by Shu Han, and it is very difficult to find a large number of people, unless you go further.

But because the external situation is already very dangerous, there are almost all demonic beasts entrenched in the remaining places to explore, Shu Han does not want to provoke them, so in this case, only the internal self to solve the population problem is the way to go, so he naturally hopes that his parents can have more children, which is also a benefit of the traditional system.

The struggle movement in Black Iron City lasted for more than two months, and various opinions were also fiercely clashed, and finally after many negotiations, it was agreed to restore the traditional system, and the two Skywalkers also returned to their own families.

However, in the process, the two Skywalkers who returned to their own families did not enjoy any good family life, in the eyes of their parents, they were just tools to fight for power and status, they were not raised personally from childhood to adulthood, and their feelings for their children were naturally not very deep, and in the end, family life was naturally full of contradictions.
