In fact, if Carlos builds a country based on the territory of South America, the scale is not small.

Mexico has a population of 8 million, and Peru and Chile have a combined population of 3 million, and this new Aztec empire will be a country with a population of more than 10 million, of which the native white people also exceed 1 million, which is no less than the population of some small European countries.

If we can rely on the native white people as the social elite, unite the mixed race as the middle class, and appease the Indians as the grassroots labor force, it will be of positive significance to promote the development of civilization in the Americas. But in Carlos's eyes, perhaps fighting the War of Succession was more important, and the Spanish colonial territory was just a tool to help him gain legitimacy.

This made the native-born white class more and more dissatisfied with Carlos, and the endless wars made them feel that Carlos had become another shackle on their heads, no different from the Spanish Empire in the past.

This contradiction accumulates day by day, and sooner or later, a new war of independence will break out.

It was the greatest victim of the world war, the Spanish Empire, who fought for power with the Carlos regime. As a dead empire, she was co-opted by Britain and the United States and drawn into a war that she could not afford to fight, and as a result, most of the colonies fell apart and were seized by China's political enemies who supported her, paying a heavy price. In the original history, they had long since lost all their colonial territories, and in this history, it was with the help of China that they maintained these territories, but they lost them because of the confrontation with China.

The situation in Spain and America has some peculiarities, whether it is the Spanish government or the Carlos regime, the strength is relatively weak, Spain has been unstable in the country, hovering between liberals and conservatives infighting, it is difficult to reach a balance, the Carlos regime has a large population, but the economy is backward, the cultural differences are huge, the internal contradictions are greater, it is difficult for both sides to integrate their national strength for war, so although the war continues, the scale has not been large, and there are few tens of thousands of people participating in the big war.

Even so, if it were not for the support of the outside world, it would be difficult for the two sides to continue fighting. Britain and the United States supported the Spanish government, which successfully established its rule on the Atlantic coast and retained most of Florida, Cuba, and New Granada. China supported the Carlos regime and allowed him to dominate the Pacific coast.

Sandwiched between the two sides are the liberal-leaning La Plata and the direct Chinese control of Panama.

Therefore, the division of the Spanish colonies is still largely the result of the great game between China and Britain.

Although China won a world war, it was not capable of directly defeating Britain, and as long as the British navy remained, Britain would always have the confidence to engage in a worldwide political and diplomatic battle with China.

The United States, at least in the Americas, began to cooperate more and more with British foreign policy, because the United States did not have the power to confront China alone, so it could only rely on the power of Britain. Without China's involvement, the United States would have been ostracized by Britain.

Of course, the political game is not static, and there is also a situation in which the United States and China jointly squeeze out Britain, but the general trend is gradually that the United States and Britain confront China.

This general trend has not improved because Huang Qiuwei replaced the crown prince in the Americas, at most it has only eased. On the one hand, the Americans are trying to strengthen their economic ties with China and the five provinces of America, and on the other hand, politically, the Americans are trying their best to reject China's eastward infiltration.

Of course, the outbreak of a war between Britain, the United States, and the West against China is still a mistake in the crown prince's administration, at least the three parties should not be allowed to confront China at the same time.

No matter how you look at it, the conflict of interests between China and Spain can be reconciled, but the contradictions with Britain and the United States cannot be resolved.

Even if Huang Qiuhou is in power, China's relations with the United States in the Americas have begun to be tense again, because the Panama Canal project built by Huang Qiuhou has already started in full swing, and once it is successfully opened, the western part of the Americas will communicate with the Gulf of Mexico, and the Chinese navy will be able to enter the Americans' doorstep at any time from the direction of the Pacific Ocean, which makes the United States feel threatened at the political level.

The British also did not want Chinese influence to penetrate into the Atlantic, so on the Panama issue, Britain and the United States were getting closer and closer. It's just a war, and they can't stop China from opening this canal for the time being. Therefore, it is logical to choose to continue to support Spain.

Ironically, if the United States controls here, it will definitely build such a canal, and the British control it will also build it. Because the opening of this canal is something that will benefit everyone, the east and west of the Americas are more closely connected, and there is an important passage between the Pacific Ocean and the Atlantic.

But whoever controls it will be resisted by the other two, and this is not about economic interests, but about national security, because either side will have a greater military advantage over the other two sides if they build a canal here.

However, whoever controls the area will not abandon the plan to build the canal. Historically, as early as 1534, King Carlos I of Spain ordered a survey of the Isthmus of Panama in an attempt to build a canal to connect the Spanish colonies on the east and west banks; The Spaniards prepared the way for the excavation of a post road through the isthmus with cobblestones along the ridge, but unfortunately the Spaniards did not have the technical ability to dig a large canal, even if the canal was less than a hundred kilometers away. In the 18th century, the Spanish colonial government successively sent personnel to explore four alternative sites, in 1771, the Isthmus of Tehuantepec, in 1779, the Isthmus of Nicaragua, and in 1814, when Spain finally decided to dig the canal, but the Latin American War of Independence broke out.

In the first year of the war, the crown prince personally led his troops, and instead of attacking the main American forces, he went south to sweep the Spanish colonies, and Panama City was occupied under this situation. The purpose was clear, it was to build a canal. During the occupation of Panama, the crown prince sent an army of mappers to conduct a detailed survey of the terrain of Panama, all the way to the Caribbean coast, drawing a detailed map with the height of each mountain.

The crown prince was transferred back to the mainland before completing the exploration, and Huang Qiuwei ruled the Americas, and then supported Carlos, abandoning Peru and Chile, but did not hand over the lands of Panama to the Carlos regime, but continued to send people to survey and select the site, and finally determined the plan to build a canal in Panama.

Spain did not have the technical ability to build the canal at that time, and in history, the French built it here for more than ten years without repairing it, and the Americans took over and repaired it for more than ten years before finally making the canal navigable. The French mainly made the same mistake as the Suez Canal, in Suez, Napoleon's engineers measured that there was a difference between the Red Sea and the Mediterranean, but in fact there was not, in Panama, the French thought that the Caribbean Sea and the Pacific Sea were parallel, and without even carrying out rigorous mapping, they blindly carried out the construction, and as a result, the first four years were almost in vain.

When Huang announced that he would build the Panama Canal, the world did not doubt China's ability to build it.

The biggest difficulty with the canal is that how to make the river over the mountains is still a technical problem in the West, and how to manage the locks for a long time is still a management problem. But no one doubts the technical and managerial ability of the Chinese, and the French books on water conservancy in China have been distributed around the world and translated into many languages. As long as Western water conservancy experts study the Lingqu, they know that the technical problems of the Chinese do not exist at all.

Although the length of the Ling Canal is not as long as the Panama Canal that is planned to be built, the nature of the project is the same, all through the sluice to ensure the passage of ships, the Chinese built a large number of ploughshares, balances, channels, culverts, steep gates, weirs, embankments, bridges on the Ling Canal, which is a small and complete engineering model. Including the water distribution function of the ploughshare, the water lifting function of the steep door, the water discharge function of the balance, the water intake irrigation function of the water culvert and so on.

Since the Panama Canal communicates with seawater, it doesn't even need to think about irrigation, so the design could be simpler. After precise measurements, the Chinese published data show that the sea surface of the Isthmus of Panama near the Pacific end is more than 20 centimeters lower than the end of the Caribbean Sea, this drop has historically killed the French, but for Chinese technology, it is not a problem, the elevation of the head of the Lingqu Canal is 212.08 meters, and the elevation of the mouth of the Linghe River is 181.8 meters, which is more than ten times that of the Panama Canal.

With this drop comparison, the shortness of the Ling Canal reflects the level of the project, with a length of more than 30 kilometers, it balances the height difference of more than 10 meters or even more than 20 meters, and there is no reason to use a length of 100 kilometers to solve the drop of 20 centimeters.

You must know that the Lingqu is a project built by the Chinese during the time of Qin Shihuang two thousand years ago, and then the world was abandoned in chaos, and the peace of the world must be restored, and the successive generations not only maintained, but also repaired, to the most valuable ship lock nature of the steep gate, to the Northern Song Dynasty, it increased by 36, and later dynasties have not exceeded this number, and the Qing Dynasty has retained 35.

Successive generations have not only been able to build and abandon the canal, but also to restore and expand, which shows that the Chinese's ability to build and manage the canal has not been lost, but has been improving.

This worries Britain and the United States even more, because China's canals are rarely built for purely economic purposes.

The history of the Chinese clearly understands that when Qin Shihuang attacked Lingnan, soldiers could not enter for three years because it was difficult to transfer military salaries. Therefore, in the twenty-eighth year of Qin Shi Huang (219 B.C.), he ordered the superintendent Yu Shilu to take charge of the supply of military supplies, and supervised the soldiers and people to build a canal between the Xiangjiang River and the Li River across Lingnan for transporting grain and wages. In the thirty-third year of Qin Shi Huang (214 BC), the Ling Canal was hewn.

The following year, Qin Shi Huang pacified Lingnan.
