In his opinion, the reason why the Holy Alliance is powerful is because the other party has improved its firearms, and now, the cannons mastered by Black Iron City are more advanced than those of the Holy Alliance, so that the enemy will definitely not compete with him in artillery, and the only thing he can rely on is the incredible number of Skywalkers.

Liu Sanyi didn't pay attention to this, in his opinion, the Holy Alliance was attacked everywhere, although its own strength was strong, but there were many enemies, it was impossible to gather all the Skywalkers together, and then start a war with Black Iron City, so no matter how much attention was paid to Black Iron City, the number of Skywalkers was at most twice that of Black Iron City, and this numerical advantage could be made up for by using the power of artillery.

To this end, Liu Sanyi's ambition to require the factory to produce more than 30 cannons in four months, which is undoubtedly a huge challenge for the factory, these cannons are not like red-coated cannons, the structure is relatively simple, only more than 100 parts, now the cannon of the Black Iron City, to improve the range, and at the same time to improve the accuracy of the shells, the number of parts is as much as more than 470, each cannon, need more than 100 skilled workers to continue to operate, to be able to assemble the completion, The difficulty of this is definitely not small, but Liu Sanyi is obviously determined to start a war, and the families also believe that it is not a good thing to sit back and wait to die, taking advantage of the current advantage in firearms and trying to create a new situation is a good thing in itself, and at the same time, it would be better if some more people could be snatched from the enemy's territory.

Now with the expansion of the territory, Black Iron City also hopes to have more people to fill these blank lands, otherwise these lands are so empty, it is a waste of vain, at this point, Shu Han also very much hopes that Liu Sanyi can do it, this time, Shu Han does not fight directly, but is commanded by Liu Sanyi himself, and the assembly of the army is after the cannon is manufactured.

However, although Shu Han did not participate in this war, he has also been in communication with Liu Sanyi for a period of time, as the only commander in Black Iron City who has the ability to lead troops alone, Liu Sanyi also needs Shu Han's opinion, for this war, Shu Han's opinion is very simple, that is, take advantage of the enemy's unpreparedness, immediately carry out a sneak attack, and then plunder their population, don't put hope on seizing the land.

First, all the land outside the forest is a plain, if there is no way to hold on to it, when the enemy's reinforcements arrive, it will directly cause the weak forces of the Black Iron City to be exposed to the enemy's strong forces, which is unfavorable for the Black Iron City, unless the Black Iron City can directly hit the Yangtze River before the enemy reacts, and occupy all the passes on the Yangtze River, so that it is possible to hold this plain under the situation of occupying the Yangtze River.

But obviously, Black Iron City still does not have such ability, according to the words of the lonely villagers, on both sides of the Yangtze River, the Holy Alliance has built a total of more than forty fortresses, each fortress has more than twenty soldiers, and food that can allow them to survive for more than a month, all fortresses are from fifteen meters underground to three meters, within eighteen meters of space, there are bedrooms, ammunition depots and grain depots, etc., it is very complete equipment, if Black Iron City wants to capture these fortresses, There must be enough artillery.

But the cannons of the Black Iron City do not have wheels, although the Black Iron City has cars, but with the classic cars that the Black Iron City has now, it can not drag these bulky cannons at all, only with a few war horses and manpower can be pulled, it is precisely because of this, it is impossible to make these cannons move quickly, but the enemy has cavalry, as long as the enemy reacts, even if it is rushed back from hundreds of kilometers away, it only takes one day, and it is impossible for the Black Iron City to occupy the entire Yangcheng Plain in one day, which is unrealistic.

Another consideration is that today's Black Iron City has tens of thousands of square kilometers of jurisdiction, including more than four or five thousand square kilometers of plains, and now the most lacking thing in Black Iron City is not land, but population.

For this point, Liu Sanyi also agrees, the purpose of the war is primary, if this point is not clear, then there will be no order when fighting, and in addition to this, Shu Han also put forward an opinion, that is, to treat these prisoners of the Holy Alliance as well as possible, for this, Shu Han is not selfish, nor is it the Holy Mother, but because it is good for Black Iron City.

In "Romance of the Three Kingdoms", Liu Bei once said to Zhuge Liang why he was able to succeed, when Mr. Kong Ming wanted Liu Xuande to seize Yizhou, Liu Xuande thought it was very immoral to do so, and Mr. Kong Ming thought that this was the land given by God to the lord, why not take it?

Liu Xuande said at the time: "Today, those who are enemies of water and fire, Cao Cao, Cao Yiyi, Cao Yiyi, I am wide; with violence, I with benevolence; with me, I with loyalty; Contrary to, things can be heard. "The meaning is Liu Bei, why I can succeed, is because Cao Cao is too impatient, then I have to be lenient, Cao Cao atrocities, I will be merciful to the people, Cao Cao is cunning, I am loyal, everything is the opposite of Cao Cao, I win.

The truth in this is undoubtedly very interesting, when Liu Bei is the opposite of Cao Cao every time, then those who oppose Cao Cao will become Liu Bei's supporters, and now Shu Han's approach is like this, now under the rule of the Holy Alliance, the people at the bottom of the city-states often live a life that is worse than death, they are brutally exploited, regarded as the wealth of the upper class, without dignity at all, like mustard.

At this time, as long as Black Iron City can give them a little care, they will quickly integrate into the social system of Black Iron City, and there will be no obstacles, and as for those who are still in the Holy Alliance, when they see how Black Iron City treats those captives and surrendered people, they will plant a seed in their hearts, although it will not have any effect in a short time, after all, the Holy Alliance is strong, and it will be difficult to deal with him, but an enemy, while being strong on the outside, does not mean that it is also strong on the inside.

Liu Bei was undoubtedly witty when he did this, but he was also helpless, helpless because his strength was too weak, so he had to stand on the opposite side of Cao Cao to succeed, if his strength was strong, he could take his own path, instead of trying to defeat Cao Cao by attacking the heart as in history.

And at this time, the same is true of Black Iron City, even if their strength is improved compared with the Holy Alliance with a population of more than two million, it is still a very weak force, in this context, hard fighting is not possible, they must rely on soft power to succeed, at this point, Shu Han does not have a Holy Heart, the so-called mercy is the hardest steel knife that Shu Han stabbed at the Holy Alliance, as long as the time is ripe, it can take the life of the Holy Alliance.

Regarding Shu Han's second suggestion, after Liu Sanyi read it, he said to his eldest son: "If I die in the future, you, as the commander, must obey Shu Han's orders, if you want to go against him, you must be 100% sure, otherwise, don't do it, he will become the most terrible commander of our Black Iron City." ”

Shu Han's two methods undoubtedly summarized Liu Sanyi's actions this time very accurately, as for other things, Shu Han did not interfere, after all, Liu Sanyi is also a general, and his command ability is needless to say, Shu Han also focused on Huajin City.

Through this year and a half of construction, at this time Joaquin City has a trace of the style of the city in later generations, the whole urban area has been planned, there are a total of three parks in the city, all of them are built very open, and there are roads in the middle to connect them, very beautiful, at the same time there are more than a dozen bathhouses in the city, both men and women have, it is convenient for people to take a bath, it can be said that today's Joaquin City is definitely the cleanest city in the entire Black Iron City system.

Under the Joaquin City, the construction of underground waterways is in full swing, compared with the buildings in the city, the buildings under the city are undoubtedly a little more difficult, but this itself is a slow effort to rush and can not be rushed, can only be built slowly, fortunately, there has been no major flood during this period of time, so that the city has not had any flood disasters, which is also the only luck.

The other is the use of power equipment, which Shu Han attaches great importance to, because if you want to develop industry, especially the industry of the second industrial revolution, it is not possible to use electricity, the size of electricity consumption, but it is a major event related to the country's industrial strength, and if you want to develop industry, it is not possible to have electricity, so Shu Han has invested great attention in the establishment of thermal power stations, and will call Duerxin almost every two or three days to ask about the situation, and a week will go to a suburban power plant to see the situation.

I have to say that Du Erxin is indeed a genius, in the research and manufacture of thermal power stations, he was able to overcome difficulties and draw the design drawings just by relying on those ancient drawings, plus the principles he mastered, which is very difficult, this is like the manufacturing principle of the atomic bomb, many people know, but how to create an atomic bomb is not so simple.

Science is difficult, science and technology is the same, otherwise anyone can make an atomic bomb, the same is true of thermal power stations, the principle is very simple, is to use coal to burn, and then let the water evaporate into water vapor, and then promote the water vapor to do work, the use of power generation groups to generate electricity, this is the basic principle, is the process of converting potential energy into kinetic energy, and then into electrical energy.

But to say simple, want to really build, the steps and processes are definitely not simple, the first is the test of safety, the family has boiled water knows, when the water is heated to the boiling point, it will begin to bubble, at that time the lid on the kettle will be opened, and then scream, and the power station is to suppress this upward force, so that these steam in a space to strengthen the pressure, and then use this pressure to promote the generator set to do work, it is conceivable, as long as there is a little leakage, Or if there is a problem with the material, the steam boiler will explode, and the entire power station will be in ruins, and the danger is very terrible.

Because of this, the key nodes are far from being able to be done with a few ancient drawings, if you want to have a full set of design drawings, at least hundreds of sheets of paper are needed to draw, and this complete set of thermal power station design drawings is not in Shu Han's hands, let alone Duerxin.

The drawings left by Su Yu are all a rough idea, that is, so that the designer can roughly determine the principle and some key steps of this thermal power station, as for how to build it, with Su Yu's ability, it is obviously impossible to get all the drawings directly, so almost all of this is Du Erxin himself with a few apprentices to figure out, this aspect makes Shu Han sigh that Du Erxin is a capable person, but at the same time, Shu Han is very unbelievable, not that Shu Han does not trust Du Erxin, but as a new product, How dangerous it is and whether its safety performance can be guaranteed is indeed a question mark, which is why the power station is built outside the city.

It is to prevent the situation from happening at that time, and Du Erxin has no way to deal with it, at that time, even if it is an explosion, at least the injured people can be controlled in the power station, and will not hurt other people, as the city lord, Shu Han naturally has to be prepared for the possibility of failure.

At the same time, on the other hand, Shu Han for the new materials required by Düerxin is to go all out to produce, mainly copper wire, the most important material for the generator set is copper wire, as the conductive performance can now find the best products, the demand for copper wire is undoubtedly very large, and the finer the better, for this reason, Shu Han increased the amount of copper mining to more than 3,000 people, and the copper produced by Zitong also gave priority to the power station, which Black Iron City is naturally very dissatisfied, after all, they are also building hydroelectric power stations, these all need copper, but Shu Han intercepted them, which naturally made the others very dissatisfied.

But Shu Han can't control them at this time, who told him that his position is very close to Zitong, take these coppers, and add more than 1,000 people in Huajin City to be responsible for refining copper ore, purifying, and manufacturing copper wire, such a huge project, only a few hundred people can be operated in modern times, and even in the case of full automation, the entire production line will not exceed 20 people, but in this era, it will take tens of thousands of people to mobilize to ensure the production of copper wire, and the output is still very low, for this, Shu Han was also helpless.
