Many of the struggles between the army and navy will eventually be reflected in the distribution of military spending.

Because both the army and the navy attach great importance to military spending, because military spending directly represents the establishment, war funds, and merit.

A large number of soldiers below are staring at it, and the bigwigs above will naturally do their best to compete.

and the head of the Operations Department of the Privy Council of the Army, the Minister on Duty in the Imperial Study, and the Army General Revan; Minister of the Navy Military Command Department, Minister on Duty in the Imperial Study, Admiral Bao Yifen, why did the two of them actually not participate in any large-scale battles, let alone outstanding merits, strictly speaking, the two of them are not even commanding generals, they can only be said to be civilian generals, but in the end, they were able to enter the Imperial Study, and even among the heroes at the end of the eighth year of Xuanping, they each became generals, and the other generals were not unconvinced.

Because, they are all representatives of the army and navy in the imperial study!

Their mission is to serve as a bridge of communication between the Holy Son of Heaven and the army and navy, and at the same time, to fight for the best interests of their respective branches of the military in the Imperial Study.

And they've done a pretty good job over the years!

Therefore, the other generals have no unconvinced thoughts about them.

In the army, in addition to the need for senior generals like Hao Bonian who can command large corps operations, there is also a need for Lei Wan, who can negotiate with the cabinet and the navy and safeguard the interests of the army in Jinling!

Bao Yifen in the navy has the same role as Lei Wan.

Therefore, on this occasion today, they also spoke most actively, Hao Bonian started, the navy followed, and then Admiral Lei Wan began to quote scriptures to join the battle group, explaining the necessity of advancing to Annam.

And when Rewan said this, he didn't just think about it from a military point of view, although he also said that the march into Annam could protect the interests of the southwest of the empire and directly threaten Malacca on land.

But he also said that there is a large-scale high-quality coal field in the northern part of Annam, and the Ministry of Commerce has noticed that in the past two years, many businessmen have imported coal from the northern part of Annam.

According to the Ministry of Commerce, the coal produced in the northern coalfields of Annam was the finest anthracite, and large coalfields capable of producing high-quality anthracite coal in large quantities had not yet been found within the empire.

What is coal used for?

The simplest is to use it as fuel, and in recent years, with the large-scale development of coalfields in the empire, and after the promotion, briquettes made from coalfields have been used as fuel for cooking and heating in many cities.

Speaking of which, the briquettes were still made by the Royal Institute of Technology under the guidance of Li Xuan!

But more importantly, coalfields are also important industrial raw materials!

Because with the continuous improvement of the steam engine at the Royal Institute of Technology, the steam engine has begun to be widely used in industry, and the first application, and the largest application at present, is to act as a pumping machine in major mines.

However, it is also gradually being used in other industries, such as the Jiangnan Textile Company, which has installed a steam engine as the power of the textile machine in the Songjiang Textile Factory under its command.

Although the current steam engine power is more expensive than the cost of water power, it has also been reduced from more than ten times in the early years to four or five times, although the cost is high, but it also brings another advantage, that is, stability!

Hydrodynamic power is affected by various external influences too much, and the power output is not stable enough, while the steam engine is not so troubled, as long as the machine is not broken, and the coal is sufficient, then it can continue to output power.

Based on the demand for civil fire heating and the gradual expansion of the industrial application of steam engines, the Ministry of Commerce has listed coal as a strategic import material, and has greatly reduced import tariffs.

At the same time, the major enterprises under the Ministry of State-owned Enterprises are also actively developing coal mines, and for this reason, the Ministry of State-owned Enterprises has even prepared a northern coal company to develop the coal fields discovered in Tangshan, Hebei Province.

In addition to coal resources, Admiral Lei Wan also highlighted the fertile land in Southeast Asia such as Annam, which is the most suitable place for growing rice, and also cited Champa rice as an example.

Champa rice is an imported multi-season rice, which is currently cultivated more in Guangdong, Guangxi, Yunnan and other regions of the empire.

With Champa rice as an example, it makes people think that the Southeast Asian peninsula is a granary with fertile land!

But the admirals are well-informed, and they just debunk the tricks of the army, saying that although the Southeast Asian Peninsula has abundant rain, the rain is too abundant, and every rainy season is flooded, and it is almost a swamp or simply a vast ocean, what kind of fields to plant!

And all kinds of poisonous insects are everywhere, the climate is quite harsh, and some areas are even worse than Luzon and Banten Islands

In this regard, the army side retorted, saying that the flooding was because the local natives did not understand water conservancy construction, and after the empire occupied the Southeast Asian Peninsula, it would definitely build a large number of water conservancy facilities, and when the time came, who would dare to say that the Southeast Asian Peninsula with abundant rain was not a granary?

As for the disease, this is a difficult problem, but if there is a problem, do you have to be afraid of it?

Moreover, the medical department of the Royal Institute of Technology has compiled a set of methods for the prevention and treatment of immigrant diseases, according to this set of methods, when the experiment was carried out on Dayuan Island, the invasion of the disease has been successfully and effectively curbed, and the mortality rate of new immigrants has been reduced from 30% to 15% within a year!

At that time, this method can also be replicated in the Southeast Asian peninsula.

When he heard Lei Wan of the army say that the mortality rate of new immigrants had been reduced from 30 percent to 15 percent, Li Xuan, who was sitting on it, sighed!

Not to mention that outsiders really don't know, the death rate of immigrants in these years is quite high!

The local immigrants from the mainland are okay, although there will be situations where they are not adapted, but they can still be overcome.

But it's much more difficult to emigrate overseas!

For example, Dayuan Island, which has been developed by the Tang Empire for many years, although this island is called the mainland, it has actually always been sparsely populated and extremely difficult to develop.

So much so that for the past few years it has been the main penal colony for criminals.

Why, because it is necessary to replenish the population of Dayuan Island by exiled criminals!

Because of the impact of water and soil adaptation, the mortality rate of immigrants to Dayuan Island has been high in recent years!

In the early years, there were 1,000 immigrants, and it would be nice to have six or seven hundred people left alive after a year, and the rest died for various reasons.

This is the case on Dayuan Island, and even more so on the Luzon and Banten sides, and the only better situation is the Ryukyu Prefecture, because this place is comparable to the climate of the empire itself, and the situation of water and soil adaptation is not so serious.

Later, Li Xuan instructed the medical department of the Royal Institute of Technology to spare some time to study some methods to prevent and treat immigrant diseases when studying corpses.

In particular, the prevention and control of mosquitoes, flies and other pests is a top priority!

The madmen of the medical department at the Royal Institute of Technology naturally took this task very seriously, and after some research, they came up with a way to prevent and treat the diseases of immigrants.

However, it is said that it is a method specifically used to prevent and treat migrant diseases, but in fact it is only a method to prevent and treat infectious diseases, and the focus is not on cure, but on prevention.

Because with the current medical department of the Royal Institute of Technology, which only stays at the level of anatomical medicine, it is not very reliable to rely on them to treat diseases, and this year, it is still traditional Chinese medicine that is more reliable, but even traditional Chinese medicine is not adapted to this so-called water and soil, in fact, it is a variety of infectious diseases, such as dengue fever, filariasis, etc.

If these viral diseases can be solved, Chinese medicine will not be Chinese medicine!

Not to mention traditional Chinese medicine, even if it is modern medicine in the 21st century, the disease of dengue fever can only be based on prevention, and the treatment can only be to treat the surface, such as bed rest, replenishment of body fluids, lowering body temperature and other auxiliary means, as for directly killing pathogens, sorry, can't do it.

Dengue fever is just one of many diseases, and with the different geographical environment and climate, there are many infectious diseases, especially in the tropics.

Therefore, the prevention and control methods of the Royal Institute of Technology Medical Department are actually also a general method for the prevention of common infectious diseases, focusing on isolating the source of pollution, including isolating the sick, cutting off the route of transmission, maintaining hygiene, doing a good job of disinfection, and protecting the vulnerable population.

And this set of methods also matches the neat and tidy appearance that the Tang Dynasty has been pursuing.

In the early years, Li Xuan hated dirty and messy, and was even more afraid of death, so he strictly required every city to do a good job of sanitation.

Therefore, in today's Tang Empire, the work of city appearance is one of the most important tasks for the chief officials of almost every city.

And this habit also continued to the overseas colonies.

But even so, the mortality rate of immigrants is too high.

After all, in the absence of various antibiotics, it is still quite difficult to fight against various infectious diseases.

But this does not mean that the empire will stop the pace of overseas immigration!

Overseas immigrants of the Empire, that is paved with bones!

Not only the corpses of the local natives, but also the corpses of their own soldiers and immigrants!

After watching the direction of the war between the army and navy from Malacca to Annam, to the entire Southeast Asian peninsula, and then to overseas colonization, sea transportation and other messy issues.

Li Xuan finally couldn't help it, and stretched out his hand slightly!

As soon as he made this move, the army and navy generals, who were still noisy and noisy, shut up in unison, and then sat down and raised their chests, because they both knew that the time for the two sides to argue had come, and it was time for the Son of Heaven to speak.

If you are not respectful, you will find death!

Watch the ministers sit down and shut up!

Li Xuan slowly looked around!

Then he said slowly: "The peninsula issue will be discussed later, and today we are talking about the Portuguese problem!" ”

In this sentence, it can be seen that the generals of the army and navy are all relieved and postpone the discussion, which means that they still have a chance!

"As for the Portuguese problem!" Li Xuan paused when he said this!
