The influx of sea boats also gave the top brass of the Ding Navy a better understanding of the ocean, and sea ships were different from their common ships, and their starting point was the largest of the river boats, which were larger, almost dozens of times the largest of the river boats.

The top leaders of the Ding Navy came from the followers in Baozhou, and a few of them were recruited after the establishment of the Ding Navy, and among them, except for a few people, the others did not know much about sea ships.

The development of the Ding Navy, from a small ship of a few hundred materials, has climbed step by step to a sail warship of 10,000 materials, and the top level of the Ding Navy feels that it is already quite powerful, seeing these 20,000 materials, or even 30,000 materials, and they are coming one after another, and they have seen too much, and they are numb.

Too much is one aspect, and on the other hand, as long as you know the future development plan of the navy, you will know that among the large ports in the navy plan, a dock of 40,000 or even 50,000 materials has already been planned.

Zhao Xin put the key to the future of the navy on the ocean, and these high-level officials of the navy also understood that the size of the dock determines the size of the shipbuilding, and the large dock can build small ships, but the small dock cannot build large ships.

The dock of 50,000 materials can build a large ship of 50,000 materials at most, even if it is the largest shipyard in the south of the Yangtze River, there is no such a large dock, they do not have a deep understanding of shipbuilding, and they do not know that when the ship is large to a certain extent, the technical difficulty will increase geometrically.

Among the Western sailing ships, the primitive warships rarely exceeded 1,500 tons, the reason for this limitation was that by the end of the 19th century, perhaps there was a certain breakthrough in technology, which might support larger ships, but the era of sails was over.

With the current level of science and technology in the 11th century, even if it is supported by a card system, the limit of the tonnage of the sail warship is only 50,000 materials, that is, the limit is about 1,600 tons, which is the limit.

For Chinese-style sailing ships, the increase in tonnage is just an increase in cargo capacity, as well as an increase in personnel, but for sail warships, the increase in tonnage is very terrible, 300 tons, 500 tons, 700 tons, 1000 tons, this represents the grade of the battleship, when the first-class battleship meets the third-class and fourth-class battleships, the numerical superiority can no longer be the focus.

The personnel of the Dinghai Navy do not doubt that the Dinghai Navy will have such a ship in a short period of time, and Zhao Xin will create such a miracle, and Zhao Xin does not doubt that it is only a matter of time before some quite advanced technologies appear and reach the peak standard of sail warships.

As an island, especially an island with industrialization as the standard, a huge problem lies in the transportation capacity, even if the Dinghai Navy is very close to Haizhou, only forty or fifty miles, but the rough sea, or make the transportation quite unfavorable, even if it has become the coast of the Northern Song Dynasty, the busiest waterway, the same is true.

Before the navy, it could only rely on its own maritime transportation capacity to support the needs of the navy, at most some merchant ships from the south, even Zhao Xin did not realize that in the Northern Song Dynasty, there was such a huge capacity.

This time the timber import, all of a sudden to release this capacity, many foreign maritime merchants joined, so that the Ding Navy of all kinds of goods more sufficient, the transportation capacity suddenly increased dozens of times, whether it is raw materials, or the transportation of goods, there is a huge improvement, the factory of the Dinghai Navy, can finally go all out to develop, do not have to wait for raw materials, manufactured goods, do not need to weigh left and right, choose the best products, but entrust this capacity to all shipped out.

Dinghai's partners throughout the Northern Song Dynasty, as well as some directly operated shops, became the direct beneficiaries of this transportation measure, especially in the south.

In itself, the Dinghai Navy established a turnover base at Hongze Lake, with Hongze Lake as the center, with the help of the Huai River, into the Beijing-Hangzhou Grand Canal, and then into the whole of northern China.

This is the focus and lifeblood of the navy, starting from the Qin and Han dynasties, the north of China, are the focus of development, here has a long history, the depth of development is also high, as long as a little recuperation, you can obtain a huge population and wealth.

However, at the beginning of the Three Kingdoms, this situation occurred slightly and deflected, especially in the Eastern Jin Dynasty, which was almost ruled by crossing the river in the south, and this passive southward migration directly affected the south, and the south began to develop.

The south of China itself is much better than the north in terms of climatic conditions, but because it has not been developed for many years, the primeval forests, and some because of the hot climate, infectious diseases and miasma have formed, which has made the south a dead land, from the Han and Tang dynasties, the south is where exile is.

The Chinese nation is industrious, and under the pressure of survival, they are not afraid of death, let alone some miasma, as long as the miasma is not close, it may not kill people, and the same is true for infectious diseases.

With the development of human activities, the miasma will gradually dissipate, so step by step from the south of Hubei, Hunan, all the way to the south of the Yangtze River, now the Yangtze River Basin, except for a few places, has become the land of fish and rice.

With the current degree of penetration of the Yangtze River, the ships opened from the Dinghai Navy can be directly transported to the hinterland of the Yangtze River, and can quickly penetrate into the middle and lower reaches of the Yangtze River through several ports.

It's just that the capacity was limited before, and only a few important cities in the south of the Yangtze River could be taken into account, at most they went up to Jiankang.

Now, with the huge capacity of sea vessels, the entire Yangtze River basin can be taken into account, and the turnover of naval commodities can be further improved.

At the same time, the emergence of these maritime merchants represents the opening of a broader market.

Every maritime merchant who crosses the ocean represents the rich man of a region, who can own more than 10,000 large ships and come to the Northern Song Dynasty with all kinds of goods, how much wealth he has, not to mention the local price of the products of the Northern Song Dynasty, compared with the local price of the Northern Song Dynasty, I don't know how many times it has increased.

The wide opening of these markets represents the products of the Dinghai Navy, which are more widely disseminated and can get more benefits for the Dinghai Navy.

Ding Haijun's products are based on the Northern Song Dynasty market, many products, the price is quite low, only enough breadth, can obtain huge benefits.

For example, Dinghai iron tools, yeast, and all kinds of basic materials, these things that must be touched in the lives of ordinary people, are the key to the benefits of Dingjun.

These things, in this era, do not meet the needs of maritime merchants.

The size of maritime merchant ships is limited, even if it is a large ship with more than 20,000 materials, or even 30,000 materials, their carrying capacity is limited, and they must bring the smallest and highest profit margin products when crossing the ocean.

These products of the Dinghai Navy are good, maybe they can be shipped overseas, and they can also get a lot of benefits, for example, iron yeast and the like, but these things, all packed together, a ship full of 30,000 materials, may be about hundreds or thousands, and the benefits, that is, thousands of yuan.

In this era, because of the unique form of navigation, the cost of thousands of miles of sea is quite high, and even the cost of staying for half a year is quite high.

Maritime merchants choose either large quantities and more expensive products, or rare and exotic treasures, only in this way can they obtain sufficient profits.

The reason why China has become the center of world commerce for a long time is very simple, China has the necessary commodities for the ocean, and the commodities that can jump dozens or even hundreds of times the profits.

In other places, maybe one, is enough for a country to gain a foothold, but in China, there are three.

Three is already the limit, even after thousands of years of development, in the eighteenth and nineteenth centuries, China's main products are still silk, tea and porcelain.

These are the ones who can get huge profits, and they can get several times, or even ten times the benefits just by transporting them from China to the Arab region, but these profits, from the Arab region to Europe, will multiply several times.

After integration, from China to Europe, high-end products such as porcelain and silk have increased a hundredfold, which is considered normal, even if it is tea, there are dozens of times the profit.

Such a product is quite rare in the whole world, from the place of origin to another place of sale, can have 10 times the profit, which is already good, 100 times, but it is very few.

However, Ding Haijun also has high-end products, such as glass products, Ding Haijun's crystal workshop, which set off a frenzy in Bianliang and attracted the attention of the nobles of the entire Northern Song Dynasty, which is not only a glass mirror, but also other whimsical designs.

The magic of nature, under the action of manpower, is even more wonderful, and it is extremely precious when glass has not yet been popularized and popularized.

This is not all the products of the Ding Navy, the weapon is the most critical, after knowing the nationality distribution of these maritime merchants, they began to develop them in a targeted manner.

Rich in some Indian Buddhist ornaments, such as glass, steel, and others, which look simple, but in line with the national conditions of each country, there are weapons, not ordinary weapons, but divine weapons.

Ordinary weapons are fine, one or two weapons may not be in the eyes of maritime merchants, but thousands of weapons can.

However, under the premise that thermal weapons cannot be popularized and the navy is not proficient in thermal weapons, it is still not allowed to export weapons on a large scale.

However, these are difficult to determine the navy, since there is no way to use ordinary weapons, ordinary weapons cannot attract the attention of maritime merchants at all under the premise of less than 10,000, and cannot meet the requirements of maritime merchants, but the magic weapons are different.

Divine weapons, in the era of cold weapons, are supreme, a brave general, and then have a suitable weapon, the combat effectiveness that bursts out must be multiplied.

However, it is said that most of them are before the Tang Dynasty, and even in the later period of the Tang Dynasty, there are not many people fighting generals, the reason is very simple, the bow and crossbow are constantly strengthened.

In the early Han and Tang dynasties, as long as there was an excellent iron armor and good force, the role of the bow and crossbow and the fierce general could be ignored and exerted to the extreme.

However, after the Han and Tang dynasties, with the improvement of the technology of making bows and crossbows, the power of bows and crossbows became stronger and stronger.

For example, the divine arm crossbow can break 700 steps, and the strength starts at more than 20 stones, no matter how strong the flesh and blood are, how can it be compared with steel, especially a large number of people gathered together to form a steel explosion, which is difficult for anyone to resist.

It stands to reason that because of the gradual decline of the fighting generals, the generals have more pursuit of divine weapons.

Although there is no fighting general, there is no way to completely exert the combat effectiveness of the divine weapon, but in the chaotic battlefield, the role of the divine weapon is still very large, and a divine weapon may be able to save lives on the battlefield.

Even if you have money, large-scale equipment with divine weapons also has a strong effect, some elites, everyone holding divine weapons, can change the pattern of the entire battlefield, and even dominate the fate of the two countries.

Just like before, during the battle of Liaoxi, which heavy armored cavalry, even if there were only 2,000 people, could cut through the camp of tens of thousands of people, and achieved a huge role in the war of 100,000 or even more.

The impact of small-scale sales of divine weapons on the Dinghai Navy and the Northern Song Dynasty is far less than that of tens of thousands, or even hundreds of thousands, of sophisticated weapons, for a very simple reason, because the Dinghai Navy has an advantage, not to mention thermal weapons.

Once it is replaced with a thermal weapon, it will be different, except for the magic weapon such as the bow and crossbow, the others face the strength of the thermal weapon, compared with ordinary weapons, there is not much difference.

In a sense, such a divine weapon has little effect on the new forbidden army of the Northern Song Dynasty, which is dominated by longbows.

No matter how thick the iron armor is, it doesn't have much effect in the face of such a divine weapon, but the steel armor is different, especially the steel armor that has passed the production of the Dinghai Navy and has been treated on the surface.

Because of mass production, their hardness is between 58 and 59, which may not be as good as a magic weapon, but it is about the same.

The effect of the divine weapon is only for ordinary iron armor, the huge hardness contrast between iron and steel, coupled with the blade that has passed a reasonable range, cut and honed, is enough to show the magic of cutting gold and breaking jade.

The steel armor is different, the hardness of itself is about the same, at most about 0.5, plus the thickness and overall performance, even if it is not as good as the magic weapon, it can also resist one or two, at least it is not a simple one or two knives can be split.

That's fine, in the longbow as the main force, the role of the heavy infantry is only to delay the edge of a part of the attacking troops, and then, when the longbow washes the ground, at this time, even if it is holding a divine weapon, facing a longbow with strong penetrating power and even armor-piercing effect, the result speaks for itself.
