America is a very magical continent, after BC, basically did not lead the entire era, but in the long history, many miraculous crops were born.

First of all, the most famous, is the three high-yield crops, this food crop is unique to the Americas, before the Age of Discovery, has been feeding the people of the Americas, but also after the emergence of the Age of Discovery, only gradually spread, these three food crops have the ability to change the whole world, South America's three high-yield plants, their emergence and widespread cultivation on other continents, has also caused a huge increase in the world's food, and then let the population expand, to a certain extent, to promote the development of the world economy and science and technology.

In fact, the Americas are more famous, and they really have to be said to be plants, not to mention food crops, tobacco, rubber, coffee, these are all native to the Americas, and even in later generations, molecules, and even deeper eras, from the primeval forests of the Americas, to obtain special plants, and then extract some effective ingredients to manufacture medicines, which is also the practice of Zhu Ahyo of the later generations of medicinal material groups.

The Americas did not develop a high degree of social civilization, nor did they form a force that influenced the whole world, but the three high-yield crops and various cash crops were the root of the Americas changing the world, and later, on the land of North America, the world's first power was born, and in the entire 20th century, and even in the 21st century, it gradually influenced the whole world and became the strongest pole in the world.

Zhao Xin set his sights on North America early on, because of the three high-yielding crops, which are the highest priority for Zhao Xin.

Food-oriented, without food, there will be no splendid civilization, even if it develops to the interstellar age, there is no way to get rid of the cultivation method, food is still very important.

Of the three high-yielding crops, the most important and the highest priority is not the other two with the highest yield, but the lowest of the three.

Originally cultivated in the Americas, after the discovery by sea, it began to spread to the whole world, and was cultivated throughout the world, and gradually became the world's third largest food crop, and corn is also known as the best quality green grain in the 21st century, which has been cultivated by the Indians of the Americas for countless years.

In terms of overall output value and nutritional value, it is not as good as wheat and rice, but the overall value is extremely high, you know, the real corn is full of treasures, its rhizomes and leaves, after a simple green storage, can become feed for livestock, reduce a large amount of food consumption, the Northern Song Dynasty, to adjust the structure, let the race develop in a better direction, meat is far better than grain.

In the era of China's material shortage, eating two or three catties of steamed buns, or nests and the like, abound, the reason is very simple, under the premise of insufficient oil and water, you can only rely on the amount to accumulate, which will add a great burden to the stomach, and at the same time, the production of muscles is not good, and the physical fitness will not go up.

Only a balanced non-staple food, increase the intake of poultry eggs, etc., is the best way, before the navy in the whole of China, popularize all kinds of breeding, but for most of the places in the Northern Song Dynasty, even people can not afford to raise, let alone animals, high-priced purchases, just let them get a certain development, not a full flowering, the real full flowering, everyone breeding in the era, must be a large number of feed to appear.

Corn is one of the most important products of feed, and the development of feed has a lot to do with corn.

In terms of comprehensive effect, corn must be the strongest, which is undoubted, but the other two are also very important, if you only solve the food problem, in fact, the other two, their effect is better.

In the Northern Song Dynasty, when the grain output was still two or three stones, four stones were already very amazing yields, these two crops could easily reach the yield of 20 stones, or even 30 stones, from the stomach and feeding more people, these two are more suitable.

Potatoes and sweet potatoes are also necessary to get, and the other, infused with tobacco, rubber, coffee, and some other cash crops, as well as a variety of spices, which is also very critical for the entire Dinghai Army, in addition to food, rubber is a must to get.

With the technology of this era, and even with the help of Zhao Xin, it is not yet possible to enter the Americas on a large scale, on the sea, there are many routes, in the age of sailing, the most important route is to take Southeast Asia, Hawaii, Midway line, and then sail directly to the Americas.

This route, in Southeast Asia and Asia, has many islands and supplies, and after passing through Hawaii, it is a smooth road, which belongs to the calmest route in the Pacific Ocean, as long as you grasp the direction, you can cross it.

No matter how calm it is, it is also the ocean, especially without islands as a reference, in the middle of the sea, it is easy to get lost.

Dinghai Navy, just going to the ocean, with the help of fishing and sparing no effort to cultivate, then trained a lot of sailors on the ocean, but these sailors, not can be wasted casually, for example, if you can use the exhaustive method, send 1,000 ocean-going ships every year, keep entering the ocean, all the way to the east, deep into the ocean, there will definitely be to reach the Americas, and even fortunately, there are back, but this method, the loss is too great.

These seeds of the sea will be tragically buried at the bottom of the sea, even in unknown places, leaving behind, perhaps one or two glorious sailors, and similar things have been done too much, and in a few decades, they will definitely be able to flow out of a suitable passage and go to the Americas.

This is not Zhao Xin's choice, and at the same time, it is too slow, so after vetoing this route, he can only pass through the northern line, along the Aleutian Islands and the islands on the American side, all the way through.

It's a place where hot and cold air currents meet, and the wind is high and the waves are strong, but it's not without its benefits, there will be no tropical hurricanes in it, even the steel battleships of the 21st century can't withstand the storm, and at the same time, there is often an island every hundreds of nautical miles.

Different from the land, on the ocean, the island is the role of the city of feudal society, not only an important node on the ocean, but also a key point of exploration.

With a fixed island, there is no need to collide with the ethereal fate through the method of one-time collision with great luck, and the method of possible death can be used to collide with the ethereal fate.

With an island as the center, as long as a supply center is built on the island, a temporary ship repair point can form a key node, and subsequent ships can reach here safely through a fixed channel, and then take the island as the center, slowly, showing a circular outward detection.

On the premise of ensuring a safe distance, gradually exploring the surrounding places clearly, there may be some twists and turns, some losses, but with the purposeless dispatch of ships to the North American continent, I don't know how much safer it is, and the efficiency is much higher.

Because of the odds of this kind of thing, good luck, maybe one in ten million odds, you got it, you are the head of good luck, perhaps, the people of Shengdou can buy lottery tickets to daydream, but a country, a force, relying on such a lottery ticket, this is very unreliable, you must rely on such a down-to-earth method, take your time.

Dingjun has almost infinite manpower, has the most terrifying production capacity in the world, and at the same time, the construction capacity is also first-class.

Zhao Xin is a traverser, in the 21st century, which construction capacity is stronger, the world to find China, China's terrible civil construction capacity, on the one hand, comes from the development of science and technology, all kinds of heavy equipment and scientific and technological development under the formation of a strong foundation, on the other hand, is the ability of Chinese to bear hardships and stand hard work, the combination of the two, is unstoppable.

Choshin chose the most difficult path, but it was the most suitable path for the navy, starting with the occupation of Jeju Island and Hokkaido.

These two large islands, which are natural bases in themselves, then follow Hokkaido, step by step, explore along this arc, and find a suitable island, first of all, construction, on the islands that can be built, build docks, bases, repair shops and supplies, and then a large number of ships come, draw nautical charts, find out the surrounding situation, and tentatively develop outward, find the next springboard, continue to repeat this action, and move forward slowly.

Before the attack on Liao, there was also the middle of the attack on Liao, because of the occupation of ships and capacity, although the production capacity of the Dinghai Navy was terrible, and the new ships were constantly launched, if they could, the tonnage could be doubled every year, but there was no way to speed up the training of talents.

Ocean voyages are very demanding for sailors, and in a more dangerous and high sea environment, any error in judgment and operation will make all efforts go down the drain.

If it is just ocean transportation, sailing on a fixed chart, this requirement is a little lower, but this is completely in an unfamiliar sea, a little exploration, even if the navy adopts a safe method, it is also thrilling, hitting the reef, storms, and even some other things, almost several times or even dozens of times the transportation, non-elite cannot.

From the time of the construction of the shipbuilding base, the Ding Navy began to train ocean-going sailors, but before taking the Liao State, it can not go all out, the Liao State is the first battle of the national fortune, only with the land of the Liao State, the Ding Navy has the foundation to take root, otherwise, just like some island countries in later generations, maybe when the fortune opens, it may be able to soar into the sky, but after a soaring sky, with the decline of fortune, it will be beaten back to its original shape.

Only by truly owning a huge amount of land, and owning the cities, factories and people on top of it, can a strong state be formed.

There are as many ships as there are to transport things, but there are not enough people, especially the big operation designed to the Liao State, which is related to the national fortune and involves the transportation of tens of millions of people and a large amount of material resources.

At that time, these sailors were evacuated, and even if there were some crews, they were only on a small scale, and they were only in the discovered sea area, and they could not be carried out on a large scale.

After taking the relationship between the Liao State and the Northern Song Dynasty, this process began to speed up the reconciliation with the Northern Song Dynasty, and it could be developed with great fanfare, and a large amount of human resources were obtained from the Northern Song Dynasty.

The emaciated camel is bigger than the horse, of course, this sentence is not quite correct, the Northern Song Dynasty is huge enough, and after so many years of development and accumulation, it has accumulated a considerable amount of manpower, these manpower, the Northern Song Dynasty also made use of it, but there is no way to use it very well, put it here in Dingjun, of course, it is very well used.

At the same time, after the large-scale transportation has come to an end, after a period of high-intensity transportation tasks, some half-hangers, or not very experienced, have accumulated considerable experience, and can also be independent, and these people can perform the current transportation tasks.

Before, the elites who were in the transport fleet were drawn out and continued to the east and north along the islands that had been explored in the distance, with the goal of preparing to follow these islands in northern Hokkaido, all the way to the Americas.

Of course, if you go directly to the north, Sakhalin continues north, and it should not be difficult to find the Bering Strait, which should be quite close to Hokkaido, at least twice as close as the Aleutian Islands.

But that's the worst option, for the simple reason that the Bering Strait, which is the northernmost point of the entire Northern Hemisphere, separating the Pacific Ocean from the Arctic Ocean.

The Bering Strait is very narrow, and it is not difficult to cross, but from the Bering Strait to the American continent, thousands of kilometers are a tundra, and the north of Asia is the same, so even if this is the closest road on land, even in the 21st century, there is no news that this road is connected.

The most suitable and easiest way is to gradually think about the northeast direction from Hokkaido, and then to the north of the Pacific Ocean, connect to the Aleutian Peninsula, and then go all the way to the Americas, where the dimension is still higher, but it is acceptable.

In the early days of the Northern Song Dynasty, in addition to attracting millions of foreign workers, among these people, after screening, there were almost no professionals, but the Northern Song Dynasty did not have it, after the inheritance of history, the Northern Song Dynasty had a lot of talents, a lot of talents, and did not make reasonable use of them, this part, all need to be recruited.

Dinghai does not let go of anything, as long as there is a certain amount of craftsmanship, you can give a huge amount of money to recruit, but among these, the most critical is the seafarers and sailors, and there are the craftsmen of the ship, even if these craftsmen are only building ships according to experience, they can only be conservative, but if after a series of training and development, it may not be possible to give birth to one or two talents, genius for a certain industry to promote, is obvious to all, perhaps, may not be able to give birth to Niu Dali, The genius who influences an industry, however, as long as there is a slight breakthrough, has a huge development for the navigation industry of the Dinghai Navy.
