Of course, this time can't be too long, otherwise the food in Black Iron City will not be enough, and at this time, Shu Han obviously does not have this worry, relying on the strong defense line on the north bank of the Yangtze River, Qiao Xuan wants to attack over, it is obviously not so easy, the three parties once again entered the peace before the war, of course, this kind of peace is illusory, and now everyone is only hindered by no one being able to conquer who will enter a period of calm, as long as anyone can break this balance, the war will break out immediately.

And the balance lies in the progress of science and technology, although countries now have their own black technology, but these technologies are not epoch-making, just like the hot air balloon of the Holy Alliance, its technical content is not high, after plundering a large number of people of the Holy Alliance, the Black Iron City can be copied immediately, as for the ironclad ship, although the difficulty is a little higher, but as long as there is a superb smelting industry, it can also be imitated, but the time is a little longer.

But even if it is an ironclad ship, its scope of application is relatively small, there must be big rivers, these ironclad ships can play their role, otherwise the range of the cannon can not reach at all, Shu Han has no way, these weapons in the final analysis, can not determine the outcome of the future war, can not play a decisive role, it is naturally difficult for countries to enter the defeat of the commentary in a short time.

So in order not to carry out meaningless wars, all countries have gradually stopped, and among them, the loss of Guangyuan Country is undoubtedly the largest, not only by the Holy Alliance plundered more than 300,000 people, but also by more than 200,000 people burned alive, these losses are huge, at the same time, the level of entering the Holy Alliance was taken away by the Holy Alliance, so that Guangyuan Kingdom lost the initiative, I have to say that in this battle, Guangyuan Kingdom suffered very heavy losses, and Black Iron City undoubtedly got the most benefits.

But Shu Han did not dare to take it lightly in today's strength comparison, Black Iron City is still the worst one, so he has to be more urgent than others, in the face of future wars, Shu Han discussed with everyone, and put the main research direction on machine guns, grenades and automatic rifles, as for what missiles and the like, although their power is indeed huge, but with the technology of Black Iron City today, the missile manufactured is probably a large cannonball, but it cannot be guided, and the hit ability is very limited.

And the above three, for today's Black Iron City, are all possible, and have great value, in World War I, the use of machine guns, it will greatly ensure the safety of the defender, a machine gun, a minute of bullets can reach a minimum of 700 rounds, or even 1,000 rounds, if it is a modern machine gun can reach 2,000 rounds in a short time, if it is those equipped on the cruiser machine guns, it can reach the level of 50,000 rounds a minute.

Of course, the current Black Iron City is categorically unable to create such an advanced weapon, but even the lowest-end machine gun is already a revolutionary progress for this era of widespread use of back-rifled guns, but the machine gun is very difficult, so Shu Han did not expect to be able to build it in a short time, and the same is true for automatic rifles, Shu Han's bigger idea now is to further improve the manual rifles that have been studied to a certain extent, so that their production speed can be faster. At the same time, the frequency of the bore can be reduced a little.

Compared with the rear-rifled rifle, the manual rifle is much simpler, as long as the bolt is pulled, a bullet case can be equipped with about 12 bullets, enough for the soldiers to use, but although this kind of firearm can be manufactured in today's Black Iron City, the manufacturing speed is very slow, ordinary rear-rifled rifles are produced on the assembly line, and often more than 1,000 guns can be manufactured in a month, and these manual rifles, at most more than 70 guns a month, can not fully equip the troops, and the price is very expensive.

Therefore, Shu Han hopes to reduce the technical content of this in a short period of time, reduce the parts in the firearm, or be able to manufacture parts in batches faster, which is more important for Shu Han, as for the machine gun, it takes time to study, Shu Han didn't even dare to think about it before, but now he has obtained a large number of scientific researchers, including many of the top weapon manufacturing engineers of the Holy Alliance, this will give birth to such an idea, otherwise with the power of the previous Black Iron City, They don't dare to make these things.

As for the grenade, it is relatively simple, and it can be completely solved with the technology of Black Iron City today, but one of the more important places, so the research of the grenade has also been placed in a relatively important position by Shu Han, hoping that it can be studied in a short time.

Compared with artillery shells, the use of grenades is more convenient, simple and can also adapt to a variety of different needs, corresponding to different targets for blasting, at this point, Shu Han is very hopeful that his side can win, and because of this, Shu Han has also invested a lot of money in grenades, the above three points are the main direction of Shu Han's development.

As for airplanes and tanks, with the strength of the Black Iron City today, it is naturally impossible to build, Shu Han's biggest pursuit now is for the ironclad ship, judging from the previous battle to seize the river, the combat ability of the ironclad ship is indeed very strong, and it has a decisive role in water warfare, and at the same time, there are a large number of cities in the Holy Alliance that are established by the water, which is also the norm in the agricultural era, in this case, having a strong naval army can ensure that their water territory will not be violated by the enemy, Second, he can attack the enemy's land and make the enemy useless, so at this point, Shu Han has invested a lot of money.

In the process of building the two ironclad ships, Shu Han's engineers also gradually figured out a set of methods for building warships, and then put forward new drawings to Shu Han, according to their experience and the drawings left in the pastoral era, they newly designed the hull of the warship, which is different from commercial trade ships, paying more attention to speed and the pursuit of vision, and at the same time greatly improving the balance of the hull, there will be no more embarrassing situation that the command room is located under the cannon, which is exactly what Shu Han needs, Seeing such drawings, Shu Han immediately ordered the shipyard to start construction immediately, and to build two warships within three months for the use of the country.

As for the transformation of merchant ships, it will be put down for the time being, after all, the front line now needs a large amount of goods, which requires merchant ships to transport, if the transformation is carried out at this time, the number of workers in its own shipyard is not enough, so Shu Han decisively gave up the transformation of merchant ships, of course, there are also two warships that are now enough to deal with the Holy Alliance, the Holy Alliance itself does not have ironclad ships, and now if you want to build it, even if you have drawings in your hand, it will take at least a year or two to explore before you can make it.

When I think that when Black Iron City developed ironclad ships, it took more than four years, almost five years, to find a way out of this, and finally make ironclads, the joints involved are not so simple, although the palms of the Holy Alliance have drawings of the old era, but many of the parts and designs in these drawings do not conform to this era, after all, most of the modern ships are propelled by hybrids, and there are all kinds of modern electronic components, The same thing as these antiques is completely different, so it is natural to change, and at the same time, the difference in the quality of the steel also makes a huge difference in the load of the boat, which needs to be changed.

Just like the answer to a math problem is placed in front of you, you won't be the same, advanced mathematics, Gaussian theory, even if you put the equation on your face, it won't be the same, these things, not just have drawings, and at the same time have to carry out a lot of calculations, and it is undoubtedly a huge challenge for heavy industry, with the strength of the Black Iron City, it will take four years under the leadership of Shu Han, not to mention the Holy Alliance, although they have a more powerful scientific research team, but within two years, it will definitely not be created, So at this point, Shu Han has an absolute advantage, which at least guarantees that in the next two years, it will be impossible for the Holy Alliance to regain control of the water from Shu Han's hands.

And after determining this, Shu Han can naturally build a navy in the rear, and at the same time, Shu Han will take out 50,000 of the more than 200,000 people and let them build roads, Joaquin City leads to Black Iron City, Black Iron City leads to Picheng, and the road in Foothill City must be built now, otherwise the transportation of resources is too wasteful of time, as for the road from Asakusa City to Dingbei City, it has now been paved, and there is a small tributary that can be reached, so there is no such a hurry for the time being.

So in this matter, Shu Han is not in a hurry, as for transporting materials from the south bank to the north bank, Shu Han has a large number of ships in his hands to transport, Shu Han also thought about whether to build a bridge to connect the two sides at first, so that the traffic becomes more convenient, but then think about it, forget it, first of all, the scientific and technological ability of the Black Iron City is simply unable to build such a road, if it is to be repaired, it will inevitably cost the Black Iron City a large amount of scientific research funds to solve the troubles encountered in the construction process, And now there are no more engineers in Black Iron City to devote themselves to such a protracted project.

However, Shu Han was fortunate at this time, because of the phased victory of the war, the original anxious atmosphere in the Black Iron City was now gone, replaced by excitement and excitement, and strong patriotism, although among them, the families of those victims were still very sad, but these people were only a minority, and Shu Han gave them most of the wealth brought back from the Holy Alliance, although it was not to say that it was glorious and rich, but it could definitely allow their families to spend their old age in peace, so that their children could finish college, Grow up, so as not to live up to these lives lost because of Black Iron City.

Although it is still difficult to let those relatives feel relieved, after all, these dead people will never come back, but the economic subsidies and social preferential treatment will undoubtedly allow them to live the rest of their lives without worry, and at the same time slowly come out of this sad mood, so in today's Black Iron City, they support the war, love the Black Iron City, and are optimistic about the prospects of the war.

Although these are just a mood and an attitude, they can also be transformed into productivity, for example, the two most important infrastructure projects in Black Iron City today, when the war was not smooth before, the construction speed of the project will also slow down, because the workers will also be afraid, afraid of the defeat of the war, afraid that these things will eventually make wedding dresses for others, and now the victory of the war has undoubtedly inspired everyone's spirit, at this time the battle is very brave, and the rear is responsible for logistics There are no longer any complaints, The entire Black Iron City was twisted into a rope.

As for those who were taken captive from the Holy Alliance, because they had accumulated a lot of experience in the treatment of Foothill City and Picheng before, they didn't encounter any big problems when entertaining them, although there will still be people who are dissatisfied, and some people will not be used to it, but under the treatment of carrots and sticks, most people will not have any opinions, and Shu Han also believes that soon they will integrate into the social order of Black Iron City, after all, here, they can live with others on an equal footing, Especially now, all the Skywalkers have been taken to the front line by Shu Han, they have no way to use their influence to discriminate against these people who have migrated from the Holy Alliance, as for the civilians, they don't care who these people are at all, and the speed of integration is actually quite fast.

As for the battlefield on the front line, there have been few major changes in the past month or two, and at the beginning, there will be sneak attacks or something from all sides, but the number of sneak attacks has increased, and all parties have naturally been prepared, the layout of the posts has become more professional, and at the same time, the vigilance has also increased, in this case, the basic problem is not too big, so Shu Han took advantage of this time to hand over the defense work to Lin Bida, and he returned to the Black Iron City to convene a meeting of all scientists, Many problems that were not solved before have been solved.

For example, let all the scientific research institutions in Black Iron City be organized together and set up a unified organization to manage them, so as not to waste human resources, Shu Han actually wanted to do that before, but at that time, the families controlled these human resources, and Shu Han had no way to decide.

And now, these families are fighting on the front line, naturally it is too late to stop Shu Han's actions, of course, this is not the point, the point is that now the war has given the people a sense of urgency, whoever can develop advanced weapons first, who can win the war, at this time, it is naturally much easier to absorb a large number of scientific research teams belonging to the families into the entire team of Black Iron City, even if there are many dissatisfaction in the hearts of Skywalkers, but at this time, no one dares to stand up against Shu Han, It's just slander in my heart.

Gathering these scientific research talents together, Shu Han has set up more than 30 groups under the Academy of Sciences to study different topics and projects, which are the most important in Black Iron City today, and the most of them are engineering and mechanical two majors, which is also the most realistic direction of use today, as for basic scientific research, there is only one, that is, the study of purple stone.
