On the second day after the victory over the pirates, the news had been passed back, and the top brass of the Dinghai Navy, who had been worried, finally breathed a sigh of relief, at any time, war is dangerous, even if the Dinghai Navy occupies all the advantages, but the Dinghai Navy is militarily weak, this is also an indisputable fact.

The power of the ballista and the fortress, without verification, only Zhao Xin understands for the time being, even if there are only a few thousand militiamen, they can defend the Dinghai Navy impregnably.

The idea of transcending the times is also the root of Zhao Xin's peace of mind, what he wants is never to take risks, if he takes risks, entering the palace and becoming the prince again is the best choice, he almost doesn't need to spend much energy to be able to control such a huge empire as the Northern Song Dynasty, instead of being like now, busy with his feet not touching the ground, everything in the entire Dinghai Navy needs him to worry about.

Perhaps, from the development of the Dinghai Navy, the foundation is much weaker, and there are also many difficulties, but from scratch to build, Zhao Xin's control ability is strong, coupled with the productivity brought by industrialization, and finally accumulated a huge confidence for the Dinghai Navy, in the face of this confidence, what can not be faced.

Not to mention victory, even if it fails, what can it be, the result of industrialization is that all kinds of things can be produced quickly, including the most important soldiers in the war, but some pirates, and not a head-on hard resistance to the Liao cavalry, even if the pirates from the entire East Asian sea have come, it is only tens of thousands of people, how can they helpless the powerful Dinghai.

Let the top management of the Ding Navy rest assured, this is also conducive to the development of work in all aspects, Zhao Xin reported the battle report to the top management of the Ding Navy, and the Ding Navy was also inspired.

This is not a big war, at best, it is an armed march, not even a single number of dead and wounded, when the infantry comes into contact and enters the pirate island, it is where the pirates shoot a few rounds of arrows in the camp of the pirates, of course the navy has no losses, the pirates have not suffered much losses, just a few dead, facing the strong army, they surrendered directly.

The meaning is different, this is not only the first battle of the navy to the outside, but also the first battle of the city.

The direction of the development of the navy, under the leadership of Zhao Xin, has shifted from the direction facing the mainland to the sea, what is important on the sea, ports, islands, routes, the location of this island, there is no key place, and there is no route, but the island itself is already a good place.

The area of 15 square kilometers is located in a relatively close position of the Dinghai Navy, which is the main barrier of the Dinghai Navy, and it will definitely be vigorously developed in the future.

As for how to Zhao'an, how to get the information that the pirates knew, this takes time, just now, from the hands of the pirates, I have obtained the exact location of nearly 20 islands, these islands are large and small, but all the islands have fresh water, the largest of which is even the size of the Dinghai, which is an unexpected gain.

An island about the size of the Dinghai Navy, this can accommodate some industries that the Dinghai Navy can't accommodate, and it can also accommodate more people, but in terms of location, some of them go deep into the ocean, probably more than 200 miles from the shore.

What came out of the interrogation was only the general direction, as well as how long the boat had been traveling, and from which position, which made Zhao Xin unable to judge what island it was.

In the impression, in China's coastal waters, such islands are rare, can not be Chongming Island, although it is said, Chongming Island, in 800 A.D. has appeared, but its area, is gradually increased later, at this time, is just a small sandbar at the mouth of the Yangtze River.

Then, it may be the Penghu Islands, but the Penghu Islands, their location is in the Taiwan Strait, and the total area is not large.

Zhao Xin didn't dwell on it so much, Lianyungang in later generations could become such a huge island as the Dinghai Navy, and it was not impossible for the Penghu Islands to change, and even some big islands in the sea, because of the movement of the earth's crust, or some other reasons, it may not be impossible to sink underwater.

After the success of the sailing ship, although it played an excellent role in the middle of this pirate encirclement and suppression, and in a short time, it sank many ships in the port, but it had already shown its role in this battle.

The industrialized Dinghai Navy is so advantageous, the processing of materials is very fast, the previous action is slow, because everything is new, need to be slowly explored, now, no matter what the future will be, the existing one, can also be applied, start the construction of a batch, it is inevitable.

On the day of the return of the battle report, Zhao Xin arranged the construction of at least 12 sailing ships, and after the previous experience, the keel could be built on a large scale.

The advantage of steelmaking blast furnace is that as long as the formula is studied, it can be continuously reproduced and produced, and the grinding tools that have been built can be used continuously, and the steel keel will be completed in the shortest possible time, and then a large number of personnel will be dispatched to assemble, and the 12 ships that will start construction at the same time may only take 20 days, or half a month, to complete the construction.

The emergence of a large-scale sail fleet is the moment of large-scale expansion of the navy, the vast sea, ports and islands, is the fulcrum and connection, and the route is also very important, these need to be explored by personnel.

The appearance of a pirate island made the Dinghai Navy nervous, but it did not change the established direction, and now the most important thing for the Dinghai Navy is the nautical chart drawn.

In order to draw the nautical chart, the Dinghai Navy invested a lot, and even Zhao Xin spent a long time to build a primary nautical chart, but this construction was only a foundation, and the initial nautical chart only included the Dinghai Navy, as well as the surrounding ports, and even the Yangtze River estuary was not involved.

This is the foundation and the foundation of the Dinghai Navy, and only by making the surroundings of the Dinghai Navy clear can we gradually expand on this basis.

A nautical chart is gradually expanded in the process of continuous improvement and accuracy, and now there is no problem in determining the strength of the navy in the entire Northern Song Dynasty, but personnel is a big problem.

Zhao Xin has weakened everything as much as possible, for example, there is no need for the surveyors to understand the meaning, just measuring, but this is it, and it is more difficult.

This is a completely different field, the time, the height of the sun, the angle, this is a completely new field, the same future, with the massive expansion of the Dinghai Navy, almost every ship, must have a qualified personnel.

This person is not a simple measurement, they must calculate the results of the measurement, convert it into latitude and longitude data, and then mark it on the chart.

It should be very difficult to train such a group of people in a short period of time, but it is related to the future of the navy, even if the progress is very slow, it must be done all the time.

With the help of developed shipping, a large number of people brought special things to the most important coastal areas of the Northern Song Dynasty, as well as the cities on the Yangtze River, but the distance there was a little far, and even if the data was measured, it would take time to transmit it.

The tentacles of the Dinghai Navy are only in the northern part of the Northern Song Dynasty and the Yangtze River valley for the time being, and there are no farther places, but Zhao Xin's preparations are still ongoing, for example, sending people to follow the sea ships and take a trip, if it is Southeast Asia, Japan, North Korea and the like, a year or the like, it can almost be turned around, but farther places, for example, Malacca, India, and even Arabia, it is not possible in a short time.

In the Age of European Discovery, a complete nautical chart also takes decades, or even hundreds of years, to complete, similar to the Dinghai Navy, which is already regarded as open, but there is no 10 years, and the accurate nautical chart on the East Asian side is simply impossible to complete, and as for the farther, it will take longer.

Charts are the basis of navigation, and these cannot be reduced, and they must be prepared in advance, even if they encounter danger, there is no way.

The sea itself is unpredictable, and even in the 21st century, with satellites, radars, and better communication methods, there are some very technologically advanced ships, and under such conditions, on the sea, there will be missing or sunk, and some, even in the end, have not been found.

This is also the relationship between the lack of scientific and technological development, although the earth has been able to launch space probes, has been able to make such a terrible weapon as the atomic bomb, at its peak, the atomic bomb of all countries on the earth combined, can destroy the earth more than a dozen times.

But this destruction, I'm afraid more, is located on the surface of the earth's human beings, if you want to destroy the earth, it is almost impossible, even if the Wenchuan earthquake, equivalent to 600 million tons of TNT explosion energy, will only affect the surrounding area, at most it will affect the crust of dozens of kilometers up and down.

The overall thickness of the earth's crust is more than 6,000 kilometers, and tens of kilometers are nothing.

The impact power of Comet Shoemaker-Levi-9 on Jupiter is equivalent to 750 times the TNT equivalent of the existing nuclear weapon, but these are only on the surface of Jupiter, leaving some traces, perhaps the Earth is not comparable with Jupiter in terms of size, but it is purely solid Earth, and its resistance is also higher than that of Jupiter.

Being able to launch a spaceship, or even landing on the moon in the 21st century, space exploration, and understanding the Earth itself are two different things.

Being able to leave the Earth's gravitational spaceship, but there is no way to get a tool to dig deep into the earth's crust, the resources consumed to excavate the Earth are far more than landing on the moon, and scientific researchers' understanding of the Earth is mostly through some side speculation.

In this case, the understanding of the earth itself is also very superficial. Not to mention the entire crust and crust, the world's deepest drilling well is only 12,262 meters, but the diameter of the entire earth is 12,742 kilometers.

That is, drilling to the deepest place, there is not one thousandth of the earth, one thousandth of a ball, in this case, not even the fur.

The ocean, even more so, although the earth already has submarines that dive to a depth of thousands of meters, but the entire ocean is still an unknown place for the earth.

Even the continental shelf in the offshore sea has not been developed, let alone the deep sea, which is deeper into the ocean, and the deep sea is also a forbidden place for the earth at that time.

In places where satellites are full of satellites and radars of all kinds, it is difficult to find a plane wrecked in the ocean, as long as it is not floating.

A world-famous air crash in Southeast Asia, mobilized countless manpower, ships, and a large number of search teams to search millions of square kilometers of sea area, but in the end, it has not been found.

The more you know, the more awe-inspiring, Zhao Xin knows his own value very well, he is irreplaceable, although he has made so many changes to the Northern Song Dynasty, even a butterfly's wings, the Western Xia has been floated away, and he has also brought a longbow that is the most suitable weapon for the Northern Song Dynasty, but as long as he doesn't have it, how many changes will he have in the end, it is really unknown.

The biggest possibility is that Zhao Xin helped the Northern Song Dynasty to continue his life, without the-stirring stick of Western Xia, the economic situation of the Northern Song Dynasty would be much better, and the application of the fortress and the longbow would reduce the military pressure on the Northern Song Dynasty.

However, with the state of literati in power, I am afraid that Zhao Xin's introduction of steel mills and industrial production will gradually decline, and the Northern Song Dynasty will return to the traditional level of the dynasty, perhaps better than the Northern Song Dynasty in history, and even last longer, but the inherent dynasty will definitely allow him to be replaced.

In the absence of high-yielding crops, until there was no way to solve the problem of land annexation, the fixed state of the dynasty was like this, and around 300 years, when the population increased to the point where the land could not support it, the dynasty naturally perished.

The annexation of land, as well as the consumption of the privileged class, has intensified this process, which is a fixed law of development, and there is no way to change it for the time being.

If the territory of China is expanded, it can solve part of the problem, but the control of the dynasty also has a limit, with the current communication and transportation situation, the current dynasty is already the limit, and the management of the marginal places is basically free-range, so that there will be Western Xia.

Changes in railways and various means of transportation can strengthen the cohesion of the dynasty, but in the entire Northern Song Dynasty, the places suitable for laying railways are basically traditional regions, which may be able to extend to Central Asia or Southeast Asia, but there is no way to change the overall situation.

Only Zhao Xin understood that how to develop the Northern Song Dynasty was the best, and it was meaningless to say that he would not die without the necessary certainty.

In this case, even if he is full of affection for the ocean and likes the madness of the Age of Sail, for his safety, he will not rashly choose to go to sea.

It is impossible for the Dinghai Navy not to take a ship, but this boat is only limited to going back and forth between Haizhou and Dinghai, this relatively close place, the safety performance can still be guaranteed, and it is really uncontrollable when it reaches the depths of the sea.

In this era, even if there is really a sailing ship suitable for the sea, it is quite dangerous, unless it is a real steam-powered ironclad, and at the same time, it is necessary to measure and predict enough, so you will choose to take a sea ship to feel the glory of the age of sailing.
