Since human beings have the wisdom to make tools, the pace of changing the world has not slowed down, and boats and cars, these two have changed the most for land and water.

With the car, human beings can move forward quickly, turning the original end of the world into a close distance, and with the boat, they can cross the waterway that they could not cross, and move towards a wider world, and after gradually occupying the mountains, rivers and lakes, they began to move towards the ocean.

The ocean is not so easy to conquer, even in the 21st century, it is a place full of vastness and fear, let alone this era, but the pace of human conquest of nature has not stopped, and in the continuous failure, the tools to restrain the ocean have been gradually summed up.

From primitive societies, canoes, to chiseled canoes, which make people more stable on boats, to boats with sails, oars, and anchors, human tools have become more and more powerful, and they are no longer afraid of rivers, not to mention walking on the ground, and the possibility of accidents is very small.

But for the ocean, it's different, even in the 21st century, even the moon has been landed, but the bottom of the sea is still a forbidden place, a huge ocean, and the simple area is a daunting thing.

The sea water is flowing, the bottom of the ocean, is unpredictable, can not use the sea tactics, slowly groping the environment of the ocean, can only detect, speculate, and use some methods of remote sensing, but the sea water for modern radio and other tools, attenuation and offset too much, to the 21st century with advanced science and technology, in addition to the frequent access to the waterway, other places, is still unknown.

However, science and technology can not stop people from moving towards the ocean, in the primitive society, there are people going to the ocean, to the feudal society, it is even more so, the earliest record in China, the Three Kingdoms period, there are records of the discovery of Yizhou, and the connection between Japan, as early as the Han and Tang dynasties, these need to cross the sea for dozens, or even hundreds of kilometers, to be able to cross.

In the Han and Tang dynasties, there were even merchants from the Arab region, who came to China by sea for thousands of miles, and the ancient Silk Road was divided into two parts: sea and land.

It is precisely because of the vastness of the sea that the technology content of overcoming ocean ships is very high.

Sea vessels, even if the tonnage is similar to that of river boats, but the technical content is not the same, and the shipbuilding industry is one of the few technologies in feudal society that has huge technical content.

China's shipbuilding industry, from the very beginning of the development of canoes, and gradually developed a different system, a ship, is composed of all kinds of wood, but what kind of wood is used to make keel, what wood is used to make the ship, what wood is used to make the ship, what wood is used to make the mast, these are the experience and technology required, and even some ship type drawings, which are memorized in the heart of the master craftsman.

The reason why Zhao Xin chose Dinghai as the development is that Lianyungang, the largest port in central China, is definitely a prerequisite, and on the land, under the premise that he cannot hide his ambitions, the sea is the direction of inevitable development.

From the busy river transportation, Zhao Xin has seen the development of the shipbuilding industry in the Northern Song Dynasty, and the history is also clearly recorded that the shipbuilding industry in the Northern Song Dynasty is extremely developed, and since the Tang Dynasty, maritime trade has been very developed, but the top ships at that time were ships from Arabia, and the ships built by Arab shipwrights came to China thousands of miles away, and occupied most of the share of the voyage.

However, with the development of technology, at the beginning of the Song Dynasty, China's locally made ships, after absorbing various sub-projects, came to the China Development Department to have a unique type of sailing ship, Chinese-style sailing ships.

This was a backward sailing ship in the fourteenth and fifteenth century, but in the 11th century, when Europe was still playing with ordinary monorails, the Northern Song Dynasty had already given birth to 4,000 terrible sea ships, which had a tonnage of 1,000 tons and could even carry more than 5,000 materials at the same time.

However, in the eyes of later generations, ships with a cargo capacity of 1,000 tons are only entry-level ships that can temporarily sail on the sea.

Chinese-style sailing ships, mainly flat-bottomed, may not be very seaworthy in high sea conditions, and are easily affected by wind and waves, but under the premise of the same tonnage, his load capacity is higher, can load more cargo, and can be very large, which is the advantage of Chinese-style sailing ships.

The entire Jiangnan, large-scale shipbuilding, only a small part of the Northern Song Dynasty itself, the Northern Song Dynasty's maritime merchants, the traditional North Korean Japan, and Southeast Asia's shipping lanes, beyond the Strait of Malacca, it is not easy for maritime merchants to get involved.

Chinese sailing ships are of good quality and low price, so they have attracted many overseas orders, and the general shipyards, as long as there are no large-scale accidents, are basically developing very well.

In Zhao Xin's view, the shipbuilding industry, which could be piled up as long as it cost money, was hindered in the Northern Song Dynasty, and the shipbuilding industry did not concentrate enough craftsmen in a short period of time like blacksmiths.

It is very difficult for such a stable shipbuilding factory to recruit personnel from the middle.

The original stable environment, coupled with the intricate clan relations in feudal society, is not something that you can recruit with two or three times your salary.

In particular, some masters and cores either have very high salaries, or they rely on marriages themselves, and their relatives are enveloped, and their departure is to pull out the radish and pile up the mud, which is difficult to achieve overnight.

Zhao Xin began to go in the wrong direction, he was like a blacksmith workshop, he set his sights on the top master, but after some efforts, there was no effect, a little bit of ability of the big work, can not be found, all of them are some broken households, and even the helpers do not have the existence of a teacher.

If Zhao Xin went to Bianliang, maybe the shipbuilding workshop would have stagnated, just taking advantage of the opportunity to set up an ironmaking plant, Zhao Xin simply sorted out the shipyard.

I'm not afraid to do it, I'm afraid to be attentive, Zhao Xin's carefulness is also visionary, and after a careful understanding, Zhao Xin found out the key to the problem.

Since the master can't help the premise that those legends who make big ships and master the core technology can't get their hands on it, then start from the next level, or even the next level, first solve the problem of whether there is one, and then consider the core technology.

Even unceremoniously said that the core technology of these ships in the Northern Song Dynasty, in Zhao Xin's view, is so thin, and the core technology spawned by countless lives and experience in the future Age of Discovery, in Zhao Xin's place, how many or how many, but based on the specialization of the art industry, there is no way to take it out, no matter how Zhao Xin is, he is just a student of history, not an engineer of engineering, and his hands-on ability is a little worse.

For example, Zhao Xin does not know smelting, but he can lay the steel foundation of the Dinghai Navy by pointing Niu Dali, and he can also rely on the guidance of shipbuilding to lay the naval foundation of the Dinghai.

A port, if you don't develop the navy and the shipbuilding industry, you will directly scrap more than half of it, which Zhao Xin knows very well, but shipbuilding is really not so easy, it was a little radical before, but it dragged down the development, and now with a correct understanding, the whole development is completely different.

In the previous direction, Zhao Xin directly aimed at the top group of craftsmen in the entire Northern Song Dynasty, and recruited direct sea ship craftsmen, which can be regarded as obtaining some, but most of them are the lowest level that has not even finished helping them, and only these will be tempted because of the relationship between Yu Lu, and everyone else is quite stable.

Since these large shipyards can't get enough manpower and can't find suitable craftsmen, then change directions, on the one hand, for some shipyards that are not well run.

There are various reasons for the poor management of these shipyards, and it may be that the ability of the craftsmen is not good, but on the whole, the strength obtained is a little stronger than that of the helpers.

However, this progress is not fast, the entire Northern Song Dynasty, whether it is river transportation, or shipping, has developed vigorously, and there are very few shipyards that really can't operate, even if they can't operate, the craftsmen who are slightly capable have been poached by other shipyards.

For the shipyard that starts construction and makes money as long as it is built, I don't know how many days the orders have been scheduled, and if there is a chance to get skilled workers, it will definitely cost money.

After Zhao Xin got feedback on the situation, he also began to change direction, extending his hand to his most powerful officialdom, especially the military of the Northern Song Dynasty.

In the Northern Song Dynasty, there is a very unique thing, the shipbuilding industry of the Northern Song Dynasty is the best in the world, and the whole world comes to buy the ships of the Northern Song Dynasty, but the official face of the Northern Song Dynasty does not attach importance to shipbuilding.

More than 100 years later, at the end of the Southern Song Dynasty, at the juncture that was already in danger, it was necessary to flee to the sea, and there were no official ships of the Song Dynasty, all of which were omenous civilian ships, which has to be said to be an irony.

Of course, Zhao Xin didn't think that in the official face of the Northern Song Dynasty, he would find a few masters, but some qualified craftsmen were still possible, Zhao Xin's purpose was only to build a qualified shipyard that could produce ships, and rely on the advantages of the Dinghai Navy to gradually expand this shipyard and build suitable ships in the gradual exploration.

Although this is a little slow, on the whole, it may not necessarily be slow, the level of craftsmen, in fact, is compatible with the degree of stubbornness, in the blacksmith workshop of the Daimyo's mansion, as well as the steel mill of the Dinghai Navy, except for Niu Dali, a special case of talent, other blacksmith masters, the faster to accept new technology, is often the kind of middle-level craftsmen.

Those people themselves are produced under the guidance of the masters, obey orders, obey commands, has become a habit, change a person, change a method, instinctive resistance is relatively less, after they do it, it is easy to find the benefits, and they can better grasp it.

The same approach can still be implemented in shipbuilding, compared with the current shipbuilding technology, what Zhao Xin has is actually in hundreds of years of change, through war and death, gradually accumulated things, it is not easy to get in touch with it.

In this era, the Northern Song Dynasty did not pay attention to the ocean, but because of the vigorous development of the ocean, there were still naval armies in some key places.

For example, in the southern city and the northern land checkpoint, the goods from the sea trade will pass through these two respectively, and after paying the tax, they will enter the sales of the Northern Song Dynasty.

Because of the fee, some naval patrol battalions still have, and the area they patrol is not large, most of them are at the mouth of the river, or the location of some important islands, compared to patrolling the ocean, more patrolling the river.

There is a patrol battalion here in Haizhou, and there is a small shipyard attached to the patrol battalion, which is said to be a shipyard, but in fact, I am afraid that it can only manufacture small boats of a few dozen materials.

However, this shipyard is only unable to build larger ships because of the imperfection of various equipment, and the craftsmen are all experienced, which is what Zhao Xin values the most.

Through the relationship, after the big work was included, he began to stretch out his hand to Huainan East Road and West Road, spending a lot of favor and money, and finally reluctantly set up the shelves of the shipyard to form the Dinghai Shipyard.

In the future, this shipyard has important significance in the history of China's oceans, and even in the history of the world's oceans, and has written a strong stroke, as early as the beginning of its establishment, it is really a grass team, not to mention compared with the famous shipyards in the south of the Yangtze River, even if it is an ordinary large shipyard, it cannot be compared here.

The highest-level master engineer only has the experience of co-building an 800-material sea-going ship, and the independent construction of a 300-material ship or a river boat has nothing to do with the seagoing vessel.

When the highest tonnage of river ships has reached 1,000 materials, 300 materials of sea vessels, converted into tonnage of only more than 100 tons, can be regarded as auxiliary vessels on a huge fleet of sea vessels, and there is no even the problem of going to sea alone.

It sounds very unreliable, and even this craftsman does not have the confidence to make it, and he is not sure that he can make a ship suitable for launching the ocean, and he is already the most suitable shipbuilder that Zhao Xin can find.

The first thing Zhao Xin needs is a qualified craftsman, a good team, a shipyard that can really start construction and use various tools to build ships.

It seems that there are only a few dozen craftsmen, one or two hundred helpers, traditional shipbuilding equipment, and almost few shipyards, but it has become the beginning of the Dinghai Navy's ocean exploration, and this shipyard, which is not a prototype, has become the first step of the Dinghai Navy towards the ocean.
