In the eyes of ordinary Northern Song Dynasty officials, the Dinghai Navy is just a barren land, they do not have a deep understanding of everything about the Dinghai Navy, and even some of those who have come to the Dinghai Navy will be easily blinded by inertial thinking if they do not have a comprehensive understanding of all the scientific and technological standards of the Dinghai Navy.

If there is another traveler who comes to the Dinghai Navy, simply from the size of the Dinghai Navy, the situation of the goods handled by the port, and the output of steel, you can quickly judge the strength of the Dinghai Navy and put him in a very dangerous position.

However, at that time, in the edification of the 21st century, the result of judging science and technology, steel production, and other simple aspects was not how much more powerful their talent or intelligence was than these talents of the Northern Song Dynasty in this era, but the common sense and vision brought by the information age of the 21st century.

In the view of the Northern Song Dynasty, the real strength is the army, if you have 500 elite soldiers, you will have 500 combat effectiveness, and if you have 1000 or 2000, you will have these, some logistics, steel, and scientific and technological strength, which will not be placed in the category of evaluation at all.

In the eyes of these Northern Song Dynasty officials, all kinds of commercial achievements, this is indeed noteworthy, the soldiers and horses go first before the grain and grass are moved, the rich places can afford to raise enough soldiers, the navy has iron, can build weapons, and the population, it should be worth noting.

However, the biggest weakness of the Dinghai Navy is the land, which is a hard wound, especially in the eyes of the Northern Song Dynasty, which cannot be solved.

No matter how densely populated it is, a place only a hundred miles in size, in the eyes of any general, it does not have any strategic depth, and it is simply not enough to undertake military tasks.

The appearance of the fortress may be able to solve this problem, but at this time, even a genius commander like Di Qing has insufficient estimate of the role of the fortress, he doesn't know that the densely arranged fortress group can have a strong defense in itself, not to mention the weapons such as warships and gunpowder weapons to keep the enemy out.

It can be said that as long as the fleet and gunpowder weapons are developed, the problem of determining the navy does not exist, let alone a strait dozens of miles wide, even if it is a sea area several kilometers long, for the weak side, no matter how many people can cross it.

The leading technology is not within the reach of manpower, and only Zhao Xin can see this clearly, and other people, without this experience, will certainly not see it.

This is not something that intelligence can think of, but insight, for example, even a genius general and a genius commander as strong as Di Qing would not have thought of such a terrible defensive weapon as a fortress before he had seen it.

It can use a number of less than 1,000 people to resist 100,000 troops, or even more troops, but this kind of fortress that exists specifically for defense has successfully explained all this, even Di Qing has to admit that this is a genius, a fortress that makes defense to the extreme.

The same is true of thermal weapons, one side has a hot weapon and the other side does not, that is the difference between heaven and earth, then it is really like queuing up to be shot, the difference is that one side has a gun and the other side does not, which is no different from slaughter.

Only the traverser can realize this, and on the premise of not seeing the real thing, even if Zhao Xin unmistakably tells others that a strait is enough to block the attack of thousands of troops, I am afraid they will not believe it.

Understanding the above differences, so that the Dinghai Navy is developing rapidly, and even under the premise of accumulating terrible forces, it is still the foundation of stable development, and even now, with a population of more than one million, it has not attracted much attention.

Of course, if the navy is set to develop to 10 million, 20 million, or even 30 million people, it will be different.

The population of more than 1 million is nothing in the Northern Song Dynasty, compared to the terrible population of the Northern Song Dynasty, the population of more than 1 million is only one percent, and the population of the larger states has exceeded 1 million, and those populations are still much worse than the productivity of the Dinghai Navy.

The difference between the production efficiency of the agricultural civilization in feudal society and the level of productive forces that has entered the level of real industrialization and assembly line is heaven and earth, and the difference between this is not 10 times, but dozens of times.

That is to say, with a population of 1.2 million, the production efficiency is at least 30 times or more, so 1.2 million people can exert a productivity of nearly 40 million people.

Driven by the strong productive forces, several major fist products of the Dinghai Navy have developed rapidly, and these are the pillars of the Dinghai Navy.

Steel is one, tens of thousands of people, can produce 2.2 million tons of steel per year, and the average person, the annual output, is more than 100 tons.

This figure is very terrible, and it has exceeded the average output of China at the end of the 80s, which is the ultimate in all aspects under the premise that large-scale power tools are not widely used.

This is already very terrible for an ordinary blacksmith shop, more than 50 catties a day, and this is even without counting apprentices.

You must know that the blacksmith shop is more based on the blacksmith as the calculation, generally a mature blacksmith, if he makes kitchen knives, he can produce four or five a day, which is already a lot, that is, some large farm tools, and the more iron consuming farm tools, will consume a little more.

The output of the steel plant is strictly based on the comparison between the total output and the personnel, and the output of each person is very amazing.

Even if they expand their average output several times, in a year, ordinary blacksmiths are about two or three tons, and now the output of more scientific steelmaking blast furnaces is more than 50 times that of before, which is still for safety, reducing a lot of radical output, otherwise, it would have exceeded 4 million tons.

Now the ex-factory price of steel in steel mills is 10 Wen, but after the systematic cost reduction, the cost of steel has been reduced to a very low level, almost to the extent of less than 3 Wen, that is, the gross profit is as high as 2 times.

Not to mention the profit, according to the average ex-factory price of 10 per catty of iron, one ton is almost 20 guan, the annual output of 2.2 million tons, the total output value of 44 million guan, the profit in the middle is more than 7 percent.

The output of steelmaking is the fist product of the entire Ding Navy, most of which are supplied to the Privy Council of the Northern Song Dynasty, and have a large share, which is the direct production of military products, such as arrowheads, various weapons, and armor.

These things have a higher technical content, and of course, the profits are also higher, and these occupy almost three or four percent of the share of the entire Dinghai Navy, creating terrible profits for the Dinghai Navy every year, and becoming one of the important pillars of the Dinghai Navy.

If it is said that the output of steel is the fist product of the entire Dinghai Navy, but other various products are also a huge support, and most of these products are civilian.

Some civilian products include new products of the Dinghai Navy, such as cement, iron products and other new products, as well as some traditional products.

Compared with these new products, new products open up new markets, and traditional products are really broad, and even can occupy the market without development.

For example, the reason why the iron of the Daimyo Mansion was able to directly occupy the market of the entire Northern Song Dynasty was that the iron itself was very widely used, and the Daimyo Blacksmith Workshop reduced the cost.

This is the key, again, or under the premise of higher quality, it also reduces the cost and lowers the selling price, even if it is a little lower, it is enough to occupy the market.

The same thing, through modern production methods, reduces costs, improves efficiency, and brings about cost reductions, of course, with very strong competitiveness.

If it weren't for the popularity of the fortress, the large-scale procurement of the Privy Council, and the consumption of the navy itself, if these things were produced too much, they would be easy to squeeze and unable to be sold and generate profits.

But in daily life, the things that can be seen everywhere are different, porcelain, black pottery, all kinds of handicrafts, all kinds of iron tools, these things, are common in daily life, as long as the quality is not reduced under the premise, one or two percent of the price is reduced, it is enough to have a strong competitiveness.

Such a reduction in costs is not a problem at all for the modern production and the Dinghai Navy that adopts assembly line technology, and some efficiency improvements and cost reductions generated by large-scale production are more than one or two.

For example, the traditional black pottery kiln, one-time production, that is, tens of thousands of pieces of black pottery, in many aspects of control, is not strict, sometimes the yield can be guaranteed to be more than 7 percent is already good.

However, the Navy hired famous craftsmen from all over the country, and then through aggregation and scientific experimental methods, it reduced consumption step by step, reduced some unnecessary consumption, and also strengthened the formula and improved the efficiency of the finished product.

The energy consumption is reduced by one or two, and the yield is increased to more than ninety into eight, so that all aspects are reduced, and the cost can be reduced, which is not a reduction of one or two percent, or even a reduction of five or six percent.

Among commodities, a decrease of 10% is enough to make a family prosperous, 20% is enough to create a regional specialty, and more than 30% is incomparable, and no relationship or background can compete with it.

Just like the Daimyo Blacksmith's Workshop, even if Zhao Xin is still a prince, under the same conditions, even under the premise that the cost is slightly less, it is impossible to shake the blacksmith's order.

However, the Daimyo Blacksmith Workshop directly reduced it by half, from about 80 Wen to 40 Wen, and later, it was reduced to less than 30 Wen, which is still a finished product, not the most primitive iron material, in this case, even if Jia Chaochanggui is a privy envoy, he cannot shake such an order.

Now, other products are the same, even if they are civilian products, but they are more suitable, for the small people of Shengdou, under the premise of the same utility, they can save costs, for ordinary farmers, it is a big surprise, they can not refuse.

The handicraft industry replaced by industry will inevitably bring about the bankruptcy of the original handicraftsmen, because the wealth of the Northern Song Dynasty has not yet shown this terrible for the time being, but Zhao Xin has taken precautions, and the demand for the population is endless, as long as the shipbuilding industry develops, basically obtaining similar ocean-going ships, it will expand outward.

A fixed navy can accommodate more than 1 million people, so the many islands on the border, Taiwan, Hainan Island, and even Southeast Asia, the vast ocean will give him enough nutrients, and with the help of these nutrients to gradually develop, and eventually become a behemoth.

It is conservatively estimated that Taiwan, aside from the central mountain ranges, is enough to accommodate more than 50 million people in these plains by the sea, which is still relatively sparse under the premise that Taiwan in later generations even has a population of more than 20 million. This is on the premise that it does not circulate with the mainland, otherwise it can accommodate at least more than 50 million under the premise of large cities and concentration.

A small Shanghai has a resident population of more than 30 million, not including a large number of floating population, and the accommodation degree of a megacity is far greater than that of other cities.

A fixed navy, such a small territory, can accommodate more than 1 million people unimaginable in this era, and a larger Taiwan can accommodate even more.

Not to mention that after Taiwan, there is a smaller Hainan Island, even larger, and even rich Southeast Asian islands, which are themselves naturally distributed on the islands next to China, but after China gave up the ocean, it became someone else's fat, and now, after Zhao Xin crossed, he deeply realized that the future belongs to the premise of the ocean age, it is even more impossible to let go, and it will definitely achieve greater development.

Zhao Xin came out of the shipyard, today's progress is more satisfied, but there is a gap with what he expected, but these things are not in a hurry, can only take his time, he walked slowly on the port, the second and third phases of the port, is being carried out intensively, this is a huge modern port.

Looking at the sunset in the distance, Zhao Xin is imaginary, the Northern Song Dynasty has been almost two years, except for the first half a year, has been struggling on the premise of survival, is passive, strengthen the development of combat effectiveness, and then a year and a half, from the Daimyo Mansion to the Dingjun, all in the development of commerce and industry.

This development momentum is very ferocious, that is, after the huge accident in the ironworks, it slowed down slightly, but it still developed rapidly.

In half a year, in addition to emphasizing safe production, Zhao Xin also made some adjustments to production, from the original four-sided flowering, and gradually put it in the purposeful development.

Dingjun already has the appearance of a city, and after removing all the hidden dangers, it is moving forward steadily, but in Zhao Xin's eyes, this is still a little too slow, and the direction needs to be decided, so Zhao Xin needs to make a choice.
