Without the authorization and order from the navy, they can only develop on a small scale, because this area, in later generations, is also the more elite area of the United States, such as Los Angeles, which is the second largest city in the United States, the location of Hollywood, and for example, San Francisco, a series of port cities, here is the essence of the West Coast, these lands together, there are almost hundreds of thousands, or even close to a million square kilometers, to develop comprehensively, not only needs time, but also needs a lot of support.

Here, the problem of communication is shown, if there is a telegraph, there is no need for wired telegraphy, even if it is wireless telegraphy, as long as it crosses the ocean, through contact, it can be reached instantly, even if it is a report, you can also get feedback quickly, the speed of radio is the same as the speed of light, 300,000 kilometers per second, in the entire earth, that means 7 and a half times around the earth every second, this speed is no different from seconds.

But now, if it is a small matter, these garrisons can deal with themselves, but if it is a big matter, they can only return to the Dinghai Navy through a certain channel, report to Zhao Xin, and let Zhao Xin make a decision.

This is the disadvantage of this era, thousands of miles away, even if it is a ship, a ship like a clipper, it takes a month or two, and if you count the waters of Mexico, it will be even more distant, which is a very troublesome thing.

This is also a matter of no choice, because the ocean is vast, from the Americas to the Dinghai Navy, the road is far away, often tens of thousands of kilometers, or even more, at this time, they have not yet come into contact with the telegraph, and they do not know that there is such a thing as a cross-sea telegraph, which can be connected by two sides in an instant.

Of course, Zhao Xin knows, however, the research of cross-sea cables has not yet been finalized, but the phased results have appeared, if the navy wants, it can be laid in 3-5 years, such phased results, compared with the final one, the effect is worse, the fault tolerance rate is low, and it must be replaced every 3 years.

The construction time is 3 to 5 years, and it needs to be replaced in 3 years, that is, from the day of laying to the completion, it needs to be replaced constantly, which is unimaginable for future generations, but in this era, this has surpassed the cable telegraph cable that once spread all over the world.

When Europe and the United States started, the level of science and technology was not very high, and they only used many years and the premise of continuous development to catch up with and surpass the footsteps of the East, and finally overtook in the corner.

If Zhao Xin was not a traverser, he was just an ordinary ruler, after discovering such a telegraph line and controlling the territory of the Americas, he would almost certainly have made a move and spent a lot of money to build a cable to North America.

If nothing else, let's just say that North America, with 22 million square kilometers, a territory more than twice the size of China in later generations, is a mouth-watering territory.

Without a telegraph, it is easy to have problems in establishing a force overseas, and the tail is too big to fall, or even independent and semi-independent, but with the telegraph, coupled with the fleet across the four seas, this is not a problem at all, at least, it is impossible to have a problem during the reign of Zhao Xin.

As long as there is a buffer of decades, or even a hundred years, it is not impossible for this batch of territories to belong to China, but Zhao Xin is not a native ruler, he is a traverser.

Traversers have easier solutions, for example, wireless telegraphy, even if wireless telegraphy needs a base station, along the Pacific Ocean, the entire Aleutian Islands, all the way to build a base station, it is much stronger than submarine fiber optic cables, after all, in this era, technical indicators, and laying methods, are not satisfactory under the premise, wireless than wired, much easier.

It's just that there are still some problems in the basic theory of wireless, the emergence of the telegraph, which has promoted the generation of radio on a large scale, according to the fixed method, is helpful, rather than the initial confusion, some theories of electromagnetic waves have also begun to appear, but how to emit, amplify, and accurately transmit out, there will be a series of problems.

Although it is not difficult to emit an electromagnetic wave, it is not difficult to accept it, but it is very difficult to accurately control each one and let him carry accurate information.

Cable telegraph, in a closed wire circuit, may be affected, relatively few, and not easy to appear a series of problems, but once placed on the radio, there are many problems, for example, buildings and solid occlusion, will reflect the radio, this is actually the principle of radar, there are some materials, can be absorbed, some of the same emitted waves, can interfere, these are the problem.

The initial theory was completed and was only a basic theory, using electromagnetic waves, transmitting and receiving, and then obtaining the means of wireless communication, but laboratory research and practical application have a long way to go.

Radio research is still continuing, and it is expected that the results will take at least 2 years, this is a problem, is to wait two years, until the radio is mature, to build base stations on many islands, step by step relay, spread to North America, or through submarine cables, this point, there is no way to solve it, for the time being, the Navy is laid, only the telegraph line on the land.

This is easier, to put it bluntly, the telegraph line is just a little more precise, can be transmitted in multiple strands of cable, which is for the Dinghai Navy, to achieve this, there is no substantive problem at all, at the same time, on land, whether it is construction, or maintenance is much more convenient, telegraph really solves a lot of problems.

Without a rational development method and a quick means of communication, the communication between the Dinghai Navy and North America is destined to be very difficult, and it can take two or three months at every turn, and the timeliness is very poor.

In addition to the problem of communication, there is also the problem of range in front of the North American executors.

From the Dinghai Navy, along the Sea of Japan, all the way to the north, along the Kuril Islands to the Kamchatka Peninsula, and then along the Aleutian Islands, across the Pacific Ocean to contact the Aleutian Peninsula and the Americas, this is the Dinghai Navy, which took several years, with countless silver, blood and tears, this is a road to survey.

Since the emergence of this road, there is no obstacle between China and North America, and the perfect link can be carried out, and at the same time, in the continuous search, the Dinghai Navy has finally obtained the important food crop corn from North America, which has further improved the food security and breeding of the Dinghai Navy, and from this point, the Dinghai Navy has benefited a lot.

However, from the beginning of the development of the Americas, especially after the dozens of ports in the Americas were determined, the relationship between the coordinates of some ports and the coordinates on the charts of the Dinghai Navy was clearly indicated.

Needless to say, the longitude represents the distance, but there is a problem with the dimension, where the navy is located, the dimension should be forty or fifty degrees north latitude, if you go north, to the Kuril Islands, it may rise to 50, or even 60 degrees, and then, along the Aleutian Islands, it is another nearly straight voyage, and then to the south.

Even if there is no map, no globe, as long as you are a person with rich sailing experience, you can see the problem from these coordinates, that is, there is a detour, and there are many detours.

From 40 degrees to 60 degrees, don't look at only 20 degrees, but the road is at least more than 2,000 kilometers, if you count the sea, it is more, in North America, the more south, in this sense, purely from the latitude and longitude, at least more than 4,000 kilometers of detour.

This is not a very short distance, you know, the average daily speed of the clipper boat, is only more than 200 kilometers, that is, if you find a closer road, this can save 20 days.

For a voyage that may be 40 days, or even 50 days, 20 days is really not a small amount, and many people are wondering, is there a way to get closer?

Of course, from the Dinghai Navy, as long as you go south, along the open sea of the Philippines, it is almost the same dimension as the core region of North America, here all the way to the east, is Hawaii, and then after Hawaii, to the Americas is a flat river.

From here to the Americas, although the road is long, three or four thousand kilometers, but relatively smooth, there are hardly any major storms, or reefs and the like, and navigation is relatively easy.

As long as you find the center of the Pacific Ocean, a few important islands, and continue along these islands, it is not a difficult thing, compared to the northern route, there are fewer islands, the key islands, that is, Midway, Hawaii Island, etc., but compared with the northern route, at least more than 5,000 kilometers of voyage will be saved.

The most important thing is that this sea area is calmer than the north, with fewer storms and accidents.

Compared to the Europeans occupying the Atlantic, both storms and waves are much calmer.

But since this aspect is so easy, why didn't the navy choose such a method before, the reason is very simple, it can't be gradual, or rather, put a few ships, put them in the Pacific Ocean, sail along a certain latitude and longitude, you can definitely find the opposite side, but such uncertainty is too high, and there is no controllability, and it is easy to get lost without a perfect way of contact, and you don't even know whether the ship in front of you has found the right course or is drifting in the sea.

Zhao Xin's control ability is very strong, he doesn't like such uncertainty, but chose the more difficult north, it turns out that the north is correct, if you choose the south, the Americas are a very uncertain place, there is no direction and chart, even where the Americas are, I don't know, how to determine the course, above the sea, miss the slightest mistake for thousands of miles, in case of getting lost elsewhere, back and forth in the middle, waste of flowers splashing a lot.

Now, the Americas have been discovered, and on the east coast of the Americas, a series of ports have been set up, and these ports, all of which have coordinates.

Exploration is a difficult thing, but it is not difficult to find the shipping lane, between two points, the straight line is the shortest, linking two places with coordinates, and knowing that in the middle, there is only a vast ocean, and there is nothing to obstruct, these waterways are not difficult, even if you add the search for islands.

It doesn't matter if you find it, it doesn't matter if you don't, there is no problem with the current ships of the Navy crossing the ocean, and on the premise of determining the distance and time, the ocean is crossed by flying clippers, that is

Yes, it's just that it's more to carry food and water, if there are islands in the middle, there are relays, it's even better, if there are none, it doesn't matter, it's not an unacceptable thing, after all, whether it's clippers or Spanish sailboats, they are all ocean-going fleets, and this ocean-going fleet, itself, has the ability to cross the ocean.

This matter, but there is no need to report to Zhao Xin, exploration is the main task here, whether it is the North American continent to explore, or elsewhere, they can be self-determined, they are not qualified, to get a large-scale investment like the exploration of the Aleutian Islands and the Americas, but it should not be a problem to choose some ships and cross the ocean.

For this reason, 20 fleets were specially selected, a total of 80 ships, for the exploration fleet with deep pockets, even if these ships, these people were completely buried in the sea, without a trace, for the Dinghai, for the situation in North America has no impact, not to mention, Dinghai, even more minimal.

Nautical exploration is a game of the brave in itself, and every explorer is full of the spirit of the explorer, especially in North America, without which they cannot step out of the Dinghai Navy and fight on the ocean.

After entering the Americas, they had less exploration of the seas and shipping lanes, which represented a more stable life for the average crew, and they could enjoy peace and pay with peace and ease, but for those who were full of adventure, this life was relatively comfortable.

These unruly and adventurous people, on land, have nothing else to do except drink and fight, and they have caused a lot of trouble.

Now, 80 ships, 20 fleets, for exploring the middle of the Pacific Ocean, finding suitable islands, and exploring a new shipping lane, these immediately ushered in the pursuit of these adventurers, after selection and screening, the crew of 80 ships was quickly assembled, and then, after choosing an auspicious day of the zodiac, after worshipping the heavens, began to set off.

Regarding the exploration of navigation, under the intervention of Zhao Xin, it has changed, and after finding a waterway to North America from the northern passage with the most stupid and safest method, it is now back to the original point, navigation and exploration are the business of adventurers in themselves, a boat, or a few ships, fighting in the ocean for a long time, is what adventurers should do, and now it is back to the original point.
