The founding monarch has supreme prestige and majesty that no one dares to shake, even if the new system has not yet been produced and the new system has not been deeply rooted in the hearts of the people, but when Yu Lu Zhe was in his prime, he did not have to worry that the army would become a threat if it was handed over to someone. This confidence was not only due to Lü Zhe's prestige and majesty, but also because the Han army itself had formed a system of supervision, so the obstacles that hindered the endless expansion of the ethnic groups under Lü Zhe's leadership were only the constraints on the road.

What kind of geography is it at the moment? It is an environment where most of the non-populated areas are primeval forests and wilderness, which means that there are few people who have not walked on the roads that have not been "walked before". In this situation, transportation is also destined to be extremely underdeveloped, and many areas do not know whether they can walk, and even if they can walk, they do not know what they are going, maybe it is a smooth road, it may be a swamp, and it is more likely to be blocked by mountains that cannot be climbed.

Road construction is not a light thing in any era, even in the era of mechanical engineering machines, it will be limited by the natural environment, such as during the Han army's southern expedition, in order to make the southern expedition of the Han army have a smooth and convenient supply line, Lu Zhe not only mobilized nearly 300,000 auxiliary soldiers to repair the road, and even used nearly 300,000 prisoners, the road was finally built, but the casualties during the road construction were more than 200,000.

In the jungle environment, the construction of more than 200 miles of roads alone has caused more than 200,000 deaths and injuries, and what about the environment blocked by mountains and full of Gobi? How many dead and wounded would it take to build a gallop (national highway)?

The construction of the Nanling road leading to the counties, several roads used more than three million people, the total number of manual use is more than 20 million times, so the huge manpower and material support, or in the form of expansion on the old road have spent nearly five years, several roads with a total length of more than 2,300 miles can be regarded as completed, so how much manpower and material resources should be used to make the territory have a smooth road, and how long should the total length be?

As long as you are willing to invest a lot of manpower and material resources, roads can always be built slowly. Especially in densely populated areas, it is easier to build, after all, the use of non-agricultural busy seasons to hire manpower from the private sector can find enough manpower, and people's enthusiasm for building their own homes is quite high, but there are not many people in the frontier?

The Chinese mainland is an area where the ethnic group has lived for a long time, and no matter how difficult it is, it can be regarded as the land that has been adapted, and the area outside the traditional habitat is an unfamiliar territory for the Chinese ethnic group. The strangeness here is not only ignorance of the geographical environment, but also the failure of the body to adapt to the local climate, and some dietary surprises, which are extremely easy to produce the phenomenon of adaptation to the water and soil.

Adaptation has always been the greatest enemy of every ethnic group's territorial expansion, often resulting in the ability of armies to conquer. However, after the army successfully captured a territory at the cost of the army, the displaced native people did not adapt to the local environment and developed a terrible disease, forcing the land that had already been occupied to be abandoned.

If Lu Zhe wants to expand endlessly, the first thing to solve is the trouble caused by some unadaptation.

In fact, it is not so difficult to solve the problem of adaptation, and if you pay attention to it, you can find the answer in the shadow of the expansion of the nomads and the British Empire.

Nomads have always been able to stay in the grassland environment before the popularity of tea, and after tea drinking became a common habit, the grassland people really took the step of expanding to the non-grassland environment, and this so-called expansion is to be able to inhabit the non-grassland environment without losing a large number of people due to disease.

The grassland people have their own explanation for the pursuit of tea, saying that tea can eliminate oiliness. Anyone who has ever had a habit of drinking tea knows a little. The more greasy the food you eat, the more you drink tea, it will always make the fat in the stomach and intestines surge up, and you will have a feeling of wanting to vomit, and once you burp, you will always really vomit some fat into the mouth.

So does tea really get rid of oiliness? The answer is obvious, saying that tea can eliminate oiliness is just a cover for the steppe people. In fact, tea can have a special metabolic effect on the human body, so that the body can adapt to the unfamiliar environment, which is the most primitive way to treat soil and water adaptation.

The British colonizers had a well-known saying, "We can hold a teacup in one hand." The other holds a musket in his hand to conquer the world."

Discover the history of British colonization, all the way to the introduction of tea to Britain. The footsteps of the British are limited to Europa and the surrounding islands, the Maritime Silk Road allowed Chinese tea to be transmitted to Europa through trade, the British were the first to discover the secret from tea, and since then they have used national power to guide the people to develop the habit of drinking tea, and they have strictly promoted tea drinking in the army.

The British, who discovered the secret of tea, have been trying to obtain tea planting technology from China for centuries, and the Chinese people do not know that tea has a magical function, but tea is the bulk of foreign trade, and even more popular than ceramics, and the transportation cost of tea is far less than that of ceramics, so they naturally do not want tea planting technology to be passed on.

It is recorded that the British obtained the secret of planting tea from the Japanese side, and then the British introduced it back to Britain, but because of the relationship between soil and climate, it could not be planted in large quantities, so that the British wanted to obtain colonies in areas with similar climates, and the most ideal was of course the Chinese mainland, but it was obvious that even if the Chinese mainland continued to self-destruct itself after repeated changes of dynasty, it was not something that the British could conquer, and finally set their eyes on Indochina, which was partially colonized by Spain and France.

Many people say that the British ruled India before completing the colonization of most of the world, which is not wrong at all, but it does not only mean that the British plundered wealth from Indochina, it should include the fact that India became the largest tea planter outside the Chinese continent under the control of the British, and India under the British colonization even surpassed the Chinese mainland to become the world's largest tea planter, and extended a new tea species, that is, black tea.

On the road to conquering the world, there is always a leaf of tea that has been brewed, whether it is a habit of drinking tea or whether strange things will be added, such as flowers, milk, sugar, oil or something, but tea is a necessity on the road to conquest, and there are things that go hand in hand because of the appearance of coffee.

There are no materials for making zuò coffee on the Chinese mainland, but because of the continental shelf and the natural factors of the geographical environment, there is tea. What is more puzzling is that the people who live on the Chinese continent have not discovered the secret from tea in the long history. However, the inhabitants of the non-Chinese continent dug out the secret of tea, which is really ......

The "sharp weapon" to conquer the world, the generous gift from nature, Lu Zhe, who understands the secret, has been studying tea since he occupied Nanjun. Of course, it was not he who did the research on tea himself, but he recruited or assigned professionals to do it.

Up to now...... Wrong, it should be said that before the conquest of Lingnan, the research on tea has already achieved results, in addition to the ancient pre-Qin era of tea brewing, the process of roasting tea has been studied. However, it may be that the process is not mature, Lu Zhe always feels that the tea is not delicious, and has complained more than once.

The first to promote the habit of drinking tea was the army, and the promotion of this habit coupled with the requirements for sanitary conditions, the Han army's conquest of Lingnan did not appear large-scale water and soil adaptation, even if there was a loss, it was because of various typhoon seasons, insects, poisonous miasma, swamp factors, a small part of which were combat casualties.

In the recent Northern Expedition, in addition to grain and military equipment, the largest amount of transportation was tea. If it weren't for the fact that lemons don't have a corresponding preservation method, they may be added with lemons.

Yes, lemons are one of the gifts of nature that are indispensable for a people to expand outward, in addition to tea. It can solve a disease, that is, scurvy, which is one of the indispensable foods for navigation.

The appearance of lemons was not found on the Chinese mainland, but was discovered by the Han army in the southern expedition to the farther south of Lingnan. The Han army in the southern expedition had received orders from Lü Zhe. When you find a fresh species, you must send it back to the mainland, and there are two subsequent rice varieties and some strange plants. There are precious species of wood, and the appearance of lychee and lemon is also a trophy in the conquest.

The "prescient" Lu Zhe will solve the restrictions on the human body from some environments one by one, so that people can still maintain their health after changing the environment, so that they can continue to expand outward.

Some of the constraints restricting expansion can be solved in terms of dietary habits and medicines, but it is not that way a situation of continuous expansion can be formed, and there are many more things that need to be solved, such as the stability of the internal environment, the motivation to drive the outward expansion of the ethnic group, and the goal of permanent occupation after expansion, and many, many more......

It is impossible for a country (nation) to expand externally because of the single drive of the ruler, or it needs the fundamental needs of the state (nation).

What does it take to force a nation or ethnic group to actively seek expansion? It can be a kind of **, but this kind of ** can only be found in the ruling class, and ordinary people will not actively expand**. Then there is another way, the most direct is to create a social environment with insufficient internal living space, and produce a kind of people's most urgent need for resources, resources can be land or other things, but the most important thing is land.

The nations are about to merge with the Han state, but even if it is a merged empire, the total population of the empire will never exceed 20 million, and the population of less than 20 million will make the land area of the country have a "surplus".

Lu Zhe has been working on the increase of the population, and has introduced various reward national policies to attract people to have more children, but childbirth takes a process, and it takes a while for the baby to grow up, which is a very slow method.

Driven by a national policy to encourage childbearing, the empire may be able to grow to a population of more than 100 million or even hundreds of millions in two decades. Twenty years is a long time for Lu Zhe, and the surge in newborns will inevitably cause unimaginable pressure on society, and the cost of national incentives is even more difficult to estimate, during which the state may not be able to expand externally.

Of course, Lu Zhe can wait, twenty years later, he will only be in the prime of his forties, but there are some things that can't wait, and he can't afford to wait.

The period of trying to get the people to actively seek external expansion is too long and too long, and the ruling class needs other methods for the layout and needs of the state, so the necessary strategies have been produced.

Because of the need, the local sub-collar system and the non-local sub-feudal system were born, which was a product of the administrative system dominated by Lu Zhe, and the initial goal was to channel the internal pressure outward, both to let some careerists exert their ambitions outside of the Chinese mainland.

To put it bluntly, it was Lu Zhe's interpretation of the Zhou royal family's feudal system, which was very similar to a kind of supreme ruler who controlled the land in the central area and divided the feudal heroes on the surrounding land.

The former Zhou royal family divided the feudal feuds after gaining the world, kept the richest land for themselves, and distributed it around the "king's land", so that those feudal princes became the shield of the "king's land". Many of the lands divided by the Zhou royal family belonged to the wild areas, and the reason why the land of China has the current Cheng dù is that it has been developed by the princes from generation to generation.

With the example of the Zhou royal family, Lü Zhe kept the "local" land and chose to divide the land outside the "local", which was not a maverick method, and there was room for explanation for the criticism and rejection encountered.

The nations merged with the Han state to form an empire, except for those countries that had really died in a fundamental sense, Han Wangcheng and Zhao Wangxie chose to stay in the mainland and become a feudal king, and Wei Wangjiao clearly expressed his desire to be feudal. The attitude of King Fusu of Qin has not really been revealed, but according to Lu Zhe's guess, Fusu should also be the same choice as King Wei.

In addition to the old royal family, Lu Zhe always had to reward those civil servants and military generals who followed him, so there is a fundamental other interpretation of the local and non-local sub-collar system.

In a sense, the local sub-lordship has been made into a model similar to the original historical "Wanhu Hou", which is that no matter what the name of the lord is, it is actually a lord who enjoys how many fiefs and lords, and the restrictions encountered are not much different from the "Wanhu Hou" of previous dynasties.

The non-local sub-domain system is similar to the vassal states of the Zhou royal family, and the rights they enjoy will be relatively large, and it will not be like the local lords who are restricted to death.

The princes who were divided into "local" areas because of their merits would need to "build from scratch" like the princes under the Zhou royal family, but one thing was different from the Zhou royal period, and that was that Lu Zhe would support him in some ways.

Let's examine how big the "world" obtained by the Zhou royal family was, and how much the princes who were divided into feudal areas expanded.

Maybe...... No, it was not perhaps, it was Lu Zhe who adopted such a strategy, and the starting point was to let those princes who had been divided out once again become the vanguard on the road of expansion! (To be continued......)
