This is undoubtedly an extremely important but also very cumbersome project, in this regard, relying on Du Erxin alone is obviously not enough, but also need more outstanding talents in engineering, but unfortunately, the generation of the Black Iron City, so that today's engineering, mechanical excellence is too few, and because of the perennial son inheritance of the father's business, resulting in the competitiveness of the Black Iron City is not strong, the whole society is very comfortable, there is not much competition, such a society, although very peaceful, there will hardly be any pressure to struggle, But at the same time, it is difficult for science and technology to progress, and at the same time, because of the shrinking population and even regression, it is precisely because of this that there are only a few dozen engineering students in universities today, the level of teachers is not high, there are very few people like Du Erxin who are interested in a subject and go to research, most of them just read, and then become professors and get paid, and there are some engineers who only have the ability to build a bridge across the river, in this situation, It was really difficult for Shu Han to transform today's gunpowder factory.

For this reason, Shu Han specially from the children in Huajin City, temporarily set up a college entrance examination, as long as the children who pass the grades, they can directly enter the university, in this way, to form their own university to cultivate talents, as for the teacher is a large number of experts such as Du Erxin, at the same time Shu Han himself also serves as a teacher, he has a large number of drawings in his hands, and at the same time he still understands basic physics and chemistry knowledge, even if he doesn't understand, he also has a systematic knowledge of these knowledge.

Therefore, Shu Han also forced himself to study, borrowed a lot of books from the library that no one had read for a long time, and then studied the materials, and at the same time found the books found from the ruins of Joaquin City and the books found from various tribes, directly built a museum in Joaquin City, after Shu Han's efforts for half a year, now there are more than 14,000 books, it can be said that covering all aspects, the entire library is directly placed on the university campus, which is convenient for students to borrow and read, and for going to college, many students are also very curious, And this time, the enrollment is not only for the people of Huajin City, but also for the people of Yangcheng, other tribes, and even the children of Zitong, Shu Han recruits all of them, as long as the test results are passed.

At the same time, due to the uneven development of various cities, the development of the city-state, so the education of the children is not the same, the children of the Black Iron City have been educated in the nursing home since childhood, and the natural level is very high, so in this regard, Shu Han takes the topic of logic overthrow, from real life, and then tests the children's logical ability, for scientists, logic is very important, the second is the ability to observe, there will be some difficult to distinguish problems in the questions raised, which requires strong observation ability, Only then can we find the mistakes and deduce the correct answers, and recruit in this way, from fifteen to twenty years old, you can sign up, and finally recruit two hundred children into the school, because now Shuhan is in urgent need of science and engineering talents, and at the same time, most of the experts in his hands are of this type, so two hundred children and one hundred and eighty people have entered the type of science and engineering.

And there are twenty more into the liberal arts, their main job is not to study literature, history and philosophy, but to follow their mentor to classify and manage the books that Hua Jincheng has now, and at the same time engage in translation work, you must know that many of the materials found in Hua Jincheng are in English, and there are also Japanese, which can be said to be very complicated, and Shu Han needs to know what is written in these materials, and at the same time, there may be a very important part of engineering.

Shu Han needs to learn more by deciphering these documents and archives, which is what liberal arts students mainly do now, and as for science and engineering, they will start to systematically study engineering, mechanics, and science and engineering content again, and the study time will be one year, during which they will be exposed to a variety of disciplines, and then according to their talents, they will be re-divided after one year, and then they will study for four years, and they can graduate after four years, of course, they can also stay in school and choose to go on to higher education, but that is later.

In this regard, Shu Han has no choice, but the talent is fatal to the whole society, and it is an extremely slow time to cultivate talents, and Shu Han does not have much time to wait, he wrote to Liu Sanyi, hoping that he can conquer the opponent's large cities on the battlefield, if he can bring back a few scientists, it would be great, yes, in the case of the inability to have professional scholars in the short term, it is obviously a good way to directly seize it from the outside.

Shu Han also has no way, otherwise this has been dragged, the electricity created by the thermal power station can only be wasted forever, and the electricity can not be converted into productivity, which is obviously not possible, and on the other hand, Shu Han can only give up the manufacture of weapons first, and start to think about other uses of electricity, first of all, the first point is to improve the convenience of the factory, in this regard, the professional knowledge involved is much easier than directly building a weapons factory, in this regard, Shu Han is eyeing the smelting of steel, yes, today's Black Iron City is no longer a small force of thousands of square kilometers, but a prince spanning tens of thousands of square kilometers, in this case, it is very difficult to rely on dirt roads and cement roads to connect with each other, whether it is the transportation and integration of materials and the exchange of personnel, new infrastructure construction is required to complete, and the railway is the place that Shu Han values.

Although the population of Black Iron City is less than 600,000 now, it is really a little difficult to build a railway of more than 200 kilometers, but there is no problem in building a railway of 70 or 80 kilometers, this railway is the railway from Zitong to Huajin City, as long as this railway can be repaired, then the time from Huajin City to Zitong can be shortened to less than half an hour, which is of great help to Huajin City.

At the same time, although there are mountains between Huajin City and Zitong, but relying on the strong infrastructure of the country in the 21st century, these places themselves have some wreckage, such as caves, which have long been excavated, and now almost a year, these caves have been found under the search of the expedition team of Huajin City, as long as they are sorted out to a certain extent, they can continue to be used, and then this road will bring huge copper production to Huajin City, and also bring opportunities for the development of Huajin City, and more importantly, the increase in steel production. For Joaquin City, steel production undoubtedly represents a country's production capacity, and before World War II, a country's steel production was often a measure of a country's strength, because whether it was building a cannon or a warship, it needed a lot of steel to complete. happy

Shu Han's plan, undoubtedly let Huajin City once again become the focus of attention, in the recent period, with the Black Iron City also from the support system to the traditional system, the opening of the market, but also let the flow of people become frequent, one after another many people from the Black Iron City to live in Huajin City, which also makes the population of Huajin City has reached nearly 70,000, although it is still not much, but for Huajin City, this is a good rhythm.

On the other hand, Liu Sanyi officially began to attack the Holy Alliance after a month of preparation, and now it has been a week, which can be said to be very smooth, after more than a year of rest, the Holy Alliance has indeed slackened on the Black Iron City, after all, there has been no war for more than a year, which makes the Holy Alliance mistakenly think that the Black Iron City is afraid, and at the same time, the war in other directions is very fierce, and they also need to transfer their forces to other places, so when Liu Sanyi attacks, There were only 3,000 soldiers of the Holy Alliance near the entire Yangcheng point, and Liu Sanyi took the entire Yangcheng in just one day, except for the main city and the fortress buildings, and with the power of the cannons, the defense line that the Holy Alliance had worked so hard to build did not play a role at all, and it was torn apart by Liu Sanyi's troops like a pile of mud.

After occupying the vast rural areas of Yangcheng, Liu Sanyi immediately began a population relocation plan, and at the same time launched an attack on the main urban area of Yangcheng, as for the dozens of fortresses scattered in the Yangcheng area, thousands of soldiers were sent to surround them, just to surround them, so that they would not come out to interrupt Liu Sanyi's logistics supply line, and on the other hand, it was to mobilize 6,000 soldiers and all 30 cannons, aiming at the walls of Yangcheng was a round of complete bombardment.

Under the powerful firepower, the city wall of Yangcheng did not have the strong defensive ability of the wall of the black iron city, and in just half a day, there was a huge crack in the city wall, and the guards of only six hundred people after the city were quickly eliminated by Liu Sanyi, and he took the army and began to relocate the entire Yangcheng.

In this process, some Yangcheng people were not willing to go, and came out to prevent Liu Sanyi's troops from destroying Yangcheng, in this regard, Liu Sanyi and Shu Han coincided, let these people continue to stay in Yangcheng, but they could not prevent others from leaving Yangcheng, as for the infrastructure in Yangcheng, Liu Sanyi did not move, but took away all the experimental equipment in the university and all the books in the entire Yangcheng, of course, gold, pearls, treasures, and the important properties in these banks were naturally taken away, a week's time, Before the enemy came, the entire Yangcheng area was almost empty, and then before the Holy Alliance arrived, he directly chose to evacuate, and went back with the remaining more than 9,000 soldiers, this time the battle eliminated as many as 1,000 enemies, and the loss of his side was only a few hundred, and the gain was as many as 60,000 people, and there were more than 70,000 gold coins, more than 300,000 silver coins, and more than 10 million copper coins, which can be calculated in tons.

At the same time, there are more than 40,000 books, more than 20 experimental tools, including more than 70 experts and scholars, all of whom were brought back by Liu Sanyi, this battle, is undoubtedly a huge victory, and after receiving Liu Sanyi's letter, Shu Han immediately expressed his hope to be able to copy a copy of these books in Huajin City, and at the same time he hoped that Liu Sanyi could send those experts to himself, and he was willing to give Liu family five percent of the shares of the thermal power station as compensation, which Liu Sanyi agreed, He didn't care about the five percent shares, for him, money was not so important, what he cared about was the prospect described by Shu Han, bullets would be able to produce tens of thousands of bullets a day, only a few workers would be needed, and the daily production of rifles would reach a hundred, if it could really be realized, then how powerful the combat effectiveness of the troops would become.

And with these people came more than 10,000 civilians, most of the 60,000 civilians brought back by Liu Sanyi this time were residents of Yangcheng, and 20,000 were brought from other city-states conquered by the Holy Alliance, in order to prevent the growth of some conquered city-states from threatening, the Holy Alliance often moved out part of their population, and these 20,000 people were forcibly relocated to Yangcheng.

These people are naturally distributed by various city-states, Joaquin City, as an important base in the rear, is naturally allocated to about 15,000 people, which makes Shu Han's plan to build a railway naturally more practical, and at the same time, there are more than 100 people who are experts to bring their families, Shu Han has built them very good apartments for them to live in, and enjoy the best treatment in Joaquin City, so that they can study with peace of mind, and at the same time, some of the people who have taken a back seat enter the university to teach, Shu Han knows very well that science and technology are the primary productive forcesAlthough this world has a strange existence like Skywalker, it does not prevent technology from helping human social life and productivity improvement.

And for this fiasco, the Holy Alliance naturally will not give up, and a month later, it mobilized more than 40,000 soldiers to storm the fortress occupied by the Black Iron City, but it is a pity that Liu Sanyi has already taken precautions, and at the same time built a fort on the commanding heights, and at this time Liu Sanyi has more than sixty cannons in his hands, of which forty are new cannons, under these cannons, it is difficult for the enemy's soldiers to get close to these fortresses, and can only rely on Skywalker to charge.

And in these fortresses, there are also Skywalkers arranged by Black Iron City, although the number is not as large as the enemy, but under the favorable terrain, it can still produce a certain advantage, at the same time, Liu Sanyi recruited two thousand soldiers as a backup, this battle lasted for about half a month, because of logistics problems The Holy Alliance chose to withdraw its troops, this battle, Black Iron City paid more than two thousand deaths, it can be said that most of them were caught off guard by Skywalker Breakthrough, resulting in losses, the number of Skywalker deaths was seven, Six of them have evolved through the core of the fierce beast, as for the Holy Alliance, it is much more miserable, as the attacker, the time and place are not the same, with more than 5,800 casualties, and as for the Skywalker, there are as many as 17 people killed, which can be said to be a heavy loss.
