There is not much information about the Ryukyus, but Zhou Zhong looked at it very carefully, just like a history of land reclamation, hundreds of people were thrown on an island, or an uncultivated island, from clearing the forest to building the foundation, they needed to do it.

A few hundred people, plus tools, and some basic supplies, just like this, to build a settlement on the island, even if there are tools for the Ding Navy, the speed is not fast.

In the first house, it took more than 20 days and almost a month to live in it, and in the previous month, it was still a tent, and then, after the follow-up materials and tools arrived, it was faster. 0

For a whole day, Zhou Zhong was here, carefully watched the entire Ding Navy, the description of the Ryukyus, had a certain understanding of the Ryukyus, and also strengthened his opinion, after the large-scale expansion of maritime transportation forces, the next development of the Ding Navy was indeed the Ryukyus.

Ryukyu is an island, a very large island, far more than the Ding Navy, the Northern Song Dynasty in this era, the elite's understanding of the island, is still placed in a similar Ding Navy, thinking that among the islands, even if there is a larger island, that is, similar to the Ding Navy.

Since the Tang Dynasty, the relationship between China and Japan has been relatively close, and it is also known that Japan is an island country, but how many people have been to Japan.

For Japan, it is more believed that it is a place similar to the Northern Song Dynasty, but it is just overseas, and it is rare to know that it is an island country.

This also has a lot to do with China's position in East Asia, China's coastal waters, there are very few larger islands, later China, the three major islands, Taiwan is the largest, more than 30,000 square kilometers, Hainan is the second largest, just a little smaller than Taiwan, but to the third, it will go to Chongming Island.

Chongming Island is the third, but there is a big gap between its area and the previous two, only less than 1,300 square kilometers, dozens of times smaller than the previous two.

Now Chongming Island, or a small sand island at the mouth of the Yangtze River, without the sediment brought by the Yangtze River, without more than 1000 years, Chongming Island does not have such a large area as in later generations, you know, in later generations have calculated, Chongming Island increases the area every year, about 10 square kilometers.

In this era, because of the dense forest, the soil and water conservation in the Yangtze River basin is still very good, and the expansion area of Chongming Island is far from that large.

Even Chongming Island, an island of more than 1,000 square kilometers, can be regarded as the third largest island, which shows the lack of islands near China, and to put it bluntly, most of China's coastal waters are small islands with a circumference of no more than 10 kilometers.

The sudden appearance of such an island as Ryukyu is really a refreshing cognition, especially Zhouzhong.

Land, in other places, may not be so important, dividing large counties and small counties, land is not the focus, population is, the more population means, the more taxes can be collected, and the more important this place is.

After arriving at the Ding Navy, the population is directly proportional to the land and economic development, a huge island of tens of thousands of square kilometers, compared with the Ding Navy, at least hundreds of times larger, such an island, must be the key to future development, the industrial zone because of the development of the Ding Navy and some plans to stop, must be placed here.

Zhou Chong, as the head of the port area, he knew some things about the Ding Navy best, and in order to cultivate their abilities, Zhao Xin opened up all the others except for some top-secret research.

Especially some new products, for example, petrochemical industry, as well as some fields of general chemical industry, although, the change of this point, some make Zhou Zhong feel incredible, two or more things, just under certain conditions, become another thing, isn't this alchemy?

But in any case, things that were expensive in the past may become very cheap, and some new products may occupy a broader market in the future.

It's just that these things have not been promoted for the time being, and the reason is the pollution that Zhao Xin said.

Pollution is definitely a new term, some nouns that he had definitely not heard of before coming to Ding Haijun.

However, after Zhao Xin explained and experimented with some living creatures, he understood that the simplest was the cement factory.

Zhao Xin's layout in the cement factory, at the beginning, there was a certain controversy, why so many areas were vacated, why those trees, why they had to be done, and why they had to wear masks in the dust workshop.

Masks are very inconvenient to wear, in winter, a little better, but in summer, it is uncomfortable.

In itself, in the dust workshop of the cement factory, it is relatively hot because of the pollution, and then wearing a mask is not an ordinary ordeal.

Even if strict regulations are made, there are people who do not follow the regulations, and even deducting money cannot stop it.

Zhao Xin is very concerned about this, dust pollution, may affect a person's life, on the one hand, he strictly requirements, let the cement factory strengthen patrols, as far as possible to eliminate the occurrence of this phenomenon, on the other hand, also did experiments.

Find a few pigs, live in a place with more dust for a long time, this is not difficult, find some cement, just raise it all day, this experiment has lasted for about a few months, such dust invasion is long-term and chronic, sometimes it takes a few years to be able to show up, fortunately, Ding Haijun does not need a few years.

Kill the pig directly, and then take it out of the lungs, and see the particles that cannot be degraded appear in the lungs, even if it is just a little bit, it is also shocking, and the thought of becoming like this, the danger that I told before may appear on them, even if it is stubborn, I accept it.

This is just one kind of pollution, in addition, toxic and harmful gases, heavy metals, and some nutrient hazards, these are all fresh, so that Zhou Zhong learned a lot.

Zhou Chong has only been here for about a year, but he has already realized that Ding Haijun is a good place, the foundation for him to climb to the top, a military state that is strong enough to influence the entire Northern Song Dynasty, and a military state with a population of millions and no worse than Bianliang, will have a very high status in the political arena of the Northern Song Dynasty in the future.

Zhou Chong is insightful, but he is born at a level, he is only a person, he has just come into contact with the political arena, and he does not have a clear understanding of the situation in the Northern Song Dynasty, so he misjudged, from the early stage of the development of the Ding Navy, at the moment when the steel plant and cement plant were built, the Ding Navy has surpassed the entire Northern Song Dynasty economy, and the emergence of Dinghai currency has laid the foundation in one fell swoop, as long as there is no general directional error, the development of the Ding Navy is not comparable to the Northern Song Dynasty.

With the existence of such a traverser as Zhao Xin, there is a mistake in direction, is it possible, as long as Zhao Xin still has direct jurisdiction over the Ding Navy, then the Ding Navy will definitely develop rapidly.

In a few months, in addition to the initial work on the stabilization base, later, a general survey of the entire island was also done.

In fact, the size of the Ryukyus has been recorded in history, but Ding Haijun did it more finely, according to the measurement, the circumference of the island was taken out, and then through the circumference, the area of the island was judged, and the error was not small, but the order of magnitude went up, that is, tens of thousands of square kilometers.

There is no laser ranging and satellites, and simple measurement cannot be very accurate, but the latitude and longitude are considered to be very small, and the basic data will come out after measuring in four directions.

Tens of thousands of square kilometers, this is a huge place, as far as an island is concerned, it is even more precious.

In Ding, the navy has determined that it will no longer develop to the land of the Northern Song Dynasty, and all that can be found is islands, such a large island, which can accommodate almost all the industries of the Ding navy.

Such a huge land, not much population, full of primeval forests, in the plains, there are no traces of people, everywhere dense forests.

After being reminded by Zhao Xin, they also sent elites to the mountains to do a small area of exploration, not to find the location of the aborigines, but to look for traces of human activities, and sure enough, they found it in the deep mountains.

At present, the indigenous people of the Ryukyus are mainly Takayama people, and they live more often in the mountains.

The Ryukyus are an island born of volcanic and crustal activity, and the violent volcanic activity has made the overall height of the Ryukyus quite high, and there are nearly 4,000 high mountains in the central mountain range of the island.

This is rare among the islands, a single mountain is nothing, but the entire island, there are more than 260 mountains, more than 3,000 meters above sea level, which is a little scary.

In any place, it is better to be a plain, whether it is a product or something else, but Taiwan is just above the Tropic of Cancer, most of the area, within 20 degrees north latitude, this area is the place where the typhoon is raging, plus it belongs to the position of the ocean current and the Pacific Ocean, and it does not suffer from dozens of typhoon signals every year, so I am sorry for the location.

The plains are all good, once the typhoon weather, the impact is the greatest, once the typhoon landfalls, even the modern houses and steel can be broken, let alone the aboriginal houses.

Perhaps, in the early days, the aborigines lived in the plains, but with the influence of nature, they gradually migrated to the high mountains.

To resist the wind, it is best to be a mountain range, the mountain peaks are raised step by step, no matter how strong the wind is, in front of the mountain peaks, it will also be greatly attenuated, especially in complex mountainous areas, strong winds will affect the periphery at most.

Even if there is danger in the mountains, the natural environment is not as good as that of the plains, but there is no danger of wind signals, and in the face of the great force of nature, the aborigines can only make a choice, which is a cruel natural choice, and it is also the result of countless blood and tears.

In the Ryukyus, the mountains are the main body, and the mountains in the middle occupy almost most of the territory of the Ryukyus, but there are also plains in the north on the edge, and the area is also very large.

Traditional wooden and stone houses, because of their strength, can not withstand a strong typhoon, but the reinforced concrete structure can, the same way, some unique design, can also reduce the impact of wind on the building, so that the city can be built.

Of course, when the typhoon comes, it will definitely have an impact, even if it is developed in the future, once the typhoon landfalls, it will cause huge losses, but compared with industry and land, everything is still acceptable.

At present, the Ding Navy has only one settlement on the Ryukyus, and in terms of selection, the personnel sent by the Ding Navy have established a temporary stronghold in the northern part of the Ryukyus, in the later Taipei, where there is not only a port, but also a vast basin, which is the best place in the whole Ryukyus.

For the time being, because of the relationship between manpower, there is no way to open up wasteland for farming, the land here is wasteland, and the long-term life of various plants is quite fertile, as long as it is planted, it will definitely get a good harvest.

Although Taipei is near the Tropic of Cancer, the climatic conditions are quite good due to the influence of sunshine and marine climate.

Now, there are too few people who have settled, and there are still quite a few people who have to be responsible for the safety and security, and the rest need to be built, and there is no time to open up the wasteland and cultivate the land.

However, the long-term gift of nature has made it a lot of food here, and the food in the wild will not be rashly practical when it is impossible to distinguish whether it is poisonous or not, and the efficiency of collection is relatively low, but just the wild animals on this basin can solve many problems.

In the beginning, under the premise of ensuring safety, sending a part of the soldiers to hunt could solve the problem of food for hundreds of people, who took root in the Ryukyus under the initial transportation conditions.

However, later, with the arrival of a large number of transportation forces as the Ding Navy solved the problem of transportation, there was basically very little hunting, and at most it was a tooth sacrifice.

The increase in transportation capacity is one aspect, the emergence of all kinds of dehydrated food and canned food, greatly reducing the supply, compared with the original, direct delivery of grain and various foods, the processed food, especially after dehydration, the weight is greatly reduced, but the nutritional value has not been reduced much.

After the dehydration of the food composed of carbohydrates and fats as the main body, the overall weight may only be a quarter of the previous one, as long as water is added, it can supplement the consumption of the day, which is equivalent to saying that the original guarantee conditions, under the premise of the same capacity, can be guaranteed four times.

The settlement has not expanded for the time being, and it is still the original personnel, even if the transportation capacity is sufficient, it has not expanded.

This Ryukyu, in Zhao Xin's plan, has this very important purpose, really get some maritime merchants to go to the island, it's not troublesome, Zhao Xin will not be afraid, the future Ding Navy Navy is the first in the world, on land, maybe someone can bare their teeth, on the sea, absolutely not.

There are really people fighting for it, it's a big deal to fight back, but there is no need for this, adding some difficulty to the Ding Navy, for the time being, only trustworthy will be sent to Ryukyu, and the information about Ryukyu is only known to a small number of people.
