In the Pacific Ocean, there are many clippers, and when they are laboriously transporting corn from far North America to China, an expansionary war is also beginning in the Dinghai Navy.

At that time, in order to divert everyone's attention and let those who are a little radical no longer refer to the impeachment of North American exploration, Zhao Xin started the Southern War, which has already been prepared, and the war that is nine out of ten is secure, once it opens, it immediately attracted everyone's attention.

The war in the south has risen, and Hainan, which has been in operation for so long, has become a large barracks, with more than 70 percent of the navy and at least 300,000 troops, stationed in Hainan.

All the way along Hainan, directly facing the Indochina Peninsula, perhaps, from the land, from the Yunnan border to the past, but there are mountains surrounded by arches, not only the mountains are steep, and the road is quite difficult, where to start, even if the Northern Song Dynasty gives way, the navy also needs to pay a huge price.

In the end, the choice was to land from Hainan, take the South China Sea, all the way to the Indochina Peninsula, and then sweep southward, starting from the direction of smooth rivers and convenient transportation.

The Indochina Peninsula, where it meets China, is a mountainous area in the eyes of the Indochina Peninsula, and it is also in the eyes of China, and the Yunnan-Guizhou Plateau, plus Guangxi, are some places with poor mountains and bad waters, and the natural barrier here is also in reality, separating the Indochina Peninsula from China.

However, if you start from Hainan, cross the South China Sea, and directly enter the port of Chengfang, then it is the essence of the entire Indochina Peninsula, which is what the French did in history, they came from Malacca, not Hainan, but the method used is also the same way.

The other way, of course, is directly to Indonesia, landing on the largest island, first controlling that island, and then gradually exploring, and putting Indonesia into the orbit, this Indonesia, although the land, slightly smaller than the Indochina Peninsula, most of the country, is densely covered with islands, but its mineral resources, as well as the natural foundation, are quite good, worth taking.

A war involving more than 8,000 ships, more than 300,000 people, and two ways of annihilating the country, for the Ding Navy, there is no problem at all, not even a country that can be called a strong country, perhaps, in the Indochina Peninsula, there are some countries, in Indonesia, there are also some ancient countries, but not to mention compared with the Central Plains, even compared with the countries of the Indochina Peninsula, they are greatly inferior, at most they can only be called tribes.

These places are not powerful at all, not to mention such a powerful army as the Dinghai Navy, but to say that the army of the Northern Song Dynasty or the Liao State once it has the powerful ability to transport across the sea like the Dinghai Navy, it will definitely defeat those countries.

The reason why they can survive is not because of how powerful they are, but because of their geographical location, their location, and the protection of the ocean.

In fact, in the Ming Dynasty, when Zheng He went to the West, if he wanted to make a move against Southeast Asia, Southeast Asia was already in crisis.

Zheng He went to the Western Ocean, it was not a simple merchant fleet, it was a huge army, and there were several battles to destroy the country.

However, in the end, Zheng He's purpose was not to destroy the country, but to show the prestige of the daimyo, not to open up the territory, and these natives in Southeast Asia avoided the danger of extinction.

This luck did not last for many years, one or two hundred years after Zheng He went to the West, more powerful Western navigators arrived and announced their tragedy, for the Western navigators who swept the whole world, they did not have the so-called benevolence and morality, their means were only occupation and suppression.

If you are not convinced, if you don't want to, then kill, even the Indians can go from tens of millions to the extent of being protected, what are these Southeast Asian natives.

Now, the Dinghai Navy has replaced the Western colonists, perhaps, it will be gentle, and it will not cause so much killing, but for the natives, or these tribal kings, the effect is the same.

The two sides are not at the same level of strength, once they fight, it must be overwhelming, and the two armies of the Dinghai Navy are almost all on the march, as long as the march arrives, they can be occupied, and there may be a little bit of resistance on the road, but it is just a parade of guns, killing some people, and the natural resistance will collapse.

While occupying the land, it is also exploring the land, attacking Southeast Asia, and shifting the target is only one aspect, the more important purpose is to obtain a large amount of resources.

Since landing on the Indochina Peninsula, good news has come one after another, in Zhao Xin's memory, most of the territories worth occupying have been occupied by these armies, but those mineral deposits have not yet been discovered.

Although it is said that the Dingjun Navy carries a lot of mineral experts, but they are more familiar with minerals, only iron, coal, and a small amount of shallowly buried copper, and the rest, not good.

However, in the industry, iron is one of the minerals needed, but what China lacks the most is copper, aluminum, nickel chromium and other metals, but this needs to wait slowly, and for a considerable period of time in the future, it will be discovered through slow geological exploration.

Zhao Xin relied on his memory, and only gave a general direction, at present, he has found a lot of iron ore, coal mines, and oil, especially oil, Indochina Peninsula is not very much, but in Indonesia, there are many, and the location of several large oil fields, Zhao Xin still remembers, and even pointed out specifically.

Southeast Asia is rich in oil and gas resources, and the burial is relatively shallow, and with Zhao Xin's guidance, of course, it is easy to find, and even found some self-blowing wells, which are not easy to use for the natives, and the existence of the magic water is called the existence of the ancient magic dragon, which is highly poisonous.

I don't know if the oil is poisonous or not, but the black color of the oil, as well as the stench it emits, is still very deterrent, not to mention that these natives in Southeast Asia are afraid, even the ancients were afraid, in the Sichuan oil mine, at the beginning, it was also a Jedi.

In later generations, oil was called the bloodline of industry, and it was an indispensable thing for industry, but in this era, it was not as important as me.

At present, the petrochemical level of the navy has not yet reached the large-scale development of this resource, and in the future, there will be steamships, mainly steam ships, heavy oil tankers and internal combustion engine ships, for the time being, it is unlikely to appear, in this case, the most important fuel is still coal, not oil.

As for the petrochemical industry, although it is said that under the leadership of Zhao Xin and the gradual investment of the Ding Navy, it began to appear, and some polymer materials were developed, but it still takes time before it is really used.

On the contrary, China's relatively scarce copper, nickel-chromium and other materials, for the time being, there is no large-scale discovery, and even to a certain extent, the development of Southeast Asia is still based on occupying land and opening up plantations.

Unlike China's development, from the Yin Shang period thousands of years ago, China began to develop land on a large scale, and the hard-working Chinese kept planting various crops and fed the Chinese with countless grains.

Under the premise of underdeveloped society and insufficient productivity, the population represents the output of grain to a large extent, and China's land is not too fertile, at least compared with India and the tropics, it is far behind, but it has made up for all this with hard work, intensive cultivation, and a lot of labor, and this kind of diligence is also recognized by the world.

Compared with China, the planting conditions in Southeast Asia have always been very good, fertile land, abundant sunshine and water, for these primitive natives, it is possible to sow the seeds, do not care, can get a good harvest, and even do not need to plant, in the forest, in many environments, there are all kinds of fruits or other things, can be eaten and drunk for them, this is an objective fact that cannot be changed, but also a natural condition.

Therefore, the characteristics of Southeast Asia, greed, laziness, even later, the development of the world, the development of information, did not change.

Now, the Chinese occupy this area, facing the most fertile, and for thousands of years, there has been no large-scale cultivation of land, and it is the best choice to use it for cultivation.

However, in the south, the more tropical and humid the place, the less human activity there is, the place where there is dense forest everywhere, all kinds of naturally breeding poisonous insects, parasites, these things, are the most dangerous places for land reclamation.

In the future, if you want to develop this place, you must pay attention to this, and similarly, an important problem in Southeast Asia is malaria, which is also a very serious infectious disease in later generations, which can be transmitted by mosquitoes and other methods, and has a huge infectious effect and lethality.

However, malaria is not untreatable, and traditional Chinese medicine has been similarly documented, which can play a role in prevention and prevention.

Zhao Xin knows that the best way to treat malaria is to produce cinchona cream in the Americas, which is native to the Gangdis Mountains, is in South America, and has been widely distributed all over the world in later generations, and Indonesia is also his main production area, accounting for more than 9% of the overall production.

Before, there was no choice to attack Southeast Asia, and I was worried about this, but now, there is no problem with small-scale entry.

Some diseases, if you don't pay attention, are the gods and demons, for example, the miasma that has developed the south, the miasma may be there, but it is not the point, it is rarely fatal, what really makes the people die is the parasites all over the rivers and lakes.

Long-term in the north, because of the cold and dry relationship, there are few parasites in the water, but the south is warm and humid, giving all kinds of insects and bacteria space to grow.

Malaria is also a parasite, it is different from direct drinking, it relies on mosquito bites and other transmissions, which can provide a certain amount of protection, for example, as far as possible not to expose the body, in a certain area, to explore, for example, not to choose a more humid, dense water network place.

For the station, do a good job of mosquito control, do a good job of protection, so as to reduce the spread of malaria as much as possible, the same way, Chinese medicine for malaria also has a certain research, in the ancient prescription, there are also treatment methods for him, this point, not only in the Dinghai Navy, in the Northern Song Dynasty to make some arrangements, accumulated some diseases, and even in the early exploration, also added Chinese medicine.

After all, if you want to attack Southeast Asia, you can't just start the attack casually, and if you don't do a certain amount of exploration, don't get the nautical charts, and the location of some ports that can be docked, and make a rash decision to attack, the final result will definitely end in tragedy.

The natives and kingdoms of Southeast Asia have almost zero resistance to the Dinghai Navy, but the natural environment, the ocean and various tropical poisonous insects are blocking, and among them, the most terrible is malaria.

In the Northern Song Dynasty, the accumulation of cases in the Dinghai Navy, and at the same time sent excellent doctors to go deep into Southeast Asia, in the name of caravans, and many tribes and kingdoms in Southeast Asia to communicate, while communicating, but also did the accumulation of malaria cases, very accumulated some experience, the ancient recipes were purified and modified, assisted by some modern scientific means, and finally formed a few prescriptions, may not be able to completely cure and eliminate the impact of malaria, but as long as the multi-pronged approach, malaria, parasites and other diseases can be reduced to a minimum.

In the future, if you can enter South America, then Cinchona will be the most effective drug for treating malaria, but for the time being, it can only be in North America, maybe a year or two later, you can enter Central America, and if you go to South America, it will be two or three years later.

Central America is very complex, with vast seas and islands, and this is especially true of South America, and in this era, the entire Brazilian rainforest, which is the most complex and variable, is also a huge variable, and those that are good, such as rubber, cinchona, and many South American plants, it is not very easy to get.

As far as the navy is concerned, as long as there is no impact, or when the impact is minimized, it can be done, and on the premise that malaria and other diseases can be solved, it is logical to take the risk of attacking Southeast Asia.

In fact, all kinds of protection, doctors and prescriptions have played a very good role in prevention, although in the process of attacking Southeast Asia, among the 300,000 people, at least 5,000 people were infected with malaria, and even deaths have been recorded, but for the entire Dinghai Navy, the casualties are at an acceptable level, and will not affect the overall attack much.

When malaria is only a small impact, not a large-scale impact, the protection of Southeast Asia under the premise of the disappearance of the biggest umbrella, Southeast Asia, is only a matter of time.
