Lu Zhe actually had a big question in his heart, the records of the Western Regions in ancient Chinese history only began after the conquest, and the classics did not mention the origin of the various ethnic groups in the Western Regions, so there was no way to understand whether the ethnic groups in the Western Regions were originally aborigines or migrated from other places.

The Western Regions is a general name, and the Western Regions is also a title imposed by the Chinese ethnic groups after they conquered that land, and the locals may not call it "Western Regions".

But to be honest, who cares so much, the powerful party has the right to name everything, just like the British colonized the world, those place names have been used, and even Ah San, who was not originally a nation, was forcibly pinched into a nation by the British Governor of India. Of course, the British governor did not succeed in really forming a complex ethnic group, but allowed India to form a national consciousness and finally become independent.

What is happening in the West, and why are so many populations migrating to the East? What Lu Zhe was more curious about was that the Da Yue clan was not migrating to the west? So did the Otsutsuki clan clash with these races that migrated from west to east?

At present, the intelligence line of the Han State has not extended so far, and many things rely on rumors. Lu Zhe did not see any information about the Da Yue clan in any official documents about Saiwai, which had to make him suspect that the Da Yue clan was staggered with those races that migrated eastward.

There have been many migration tides in the history of the world, and this migration tide must have arisen because of war. According to the real historical stage, not only some ethnic groups in the west are migrating to the east, but some ethnic groups in the east are also migrating to the west, such as the Otsuki clan, which is moving from east to west.

In the era without Lü Zhe, the Qin Empire was first destroyed, and then it fell into the melee of the princes and the struggle between Chu and Han, and there was also a wave of migration in the land of China, and people from the Liaodong region poured into the Korean Peninsula. There was even a part of the Chinese ethnic group who crossed the ocean and ran to Wa Island. According to some records on Wajima, the first to bring culture were the Chinese who fled to Wadao at the end of the Qin Dynasty.

Subsequently, during the Eastern Jin Dynasty and the Northern and Southern Dynasties, a large number of Chinese people fled to Wadao, and a large number of people fled to Wadao in the following five dynasties and ten countries, so the nobles on Wadao really used the name "Hua", and until the Song Dynasty, Wadao still had the habit of going to the mainland to "cross the species".

In fact, archaeological and anthropological perspectives suggest that the Wadao people were mainly composed of the Tungusic people of Northeast Asia, the ancient Central Plains people (referring to the Chinese people of all dynasties), a small number of Wuyue people in the lower reaches of the Yangtze River, a small number of Malays, and Indochinese people in the Indochina Peninsula, and gradually migrated to the Wadao people.

What is Watari? It is the Wajima woman who ran to the Great Song Dynasty to "ask for comfort", and ran back to Wajima immediately after she became pregnant with a child, and these are not the unauthorized actions of the Wajima woman. They also did not have the ability and financial resources to do such a thing, which was an official collective act of the nobles of Wajima at that time. These Wajima women, who were pregnant with the heirs of the Great Song Dynasty, would immediately become some daimyo women when they returned to their homeland, and the children they gave birth to would later become "natural nobles".

Lu Zhe originally thought that some records were nonsense, but don't forget the era he is in now, and don't forget that he has already sent people to land on Wa Island.

Now there are a group of primitive people on the island, those primitive people are generally about 1.2 meters tall, living a life in the Stone Age, and even the use of fire has not yet reached the popularity, most of them eat raw food.

Lu Zhe is not a scholar of anthropology. I don't know what kind of race those primitive people living on Wajima are counted, but some records mention that those dwarf hominids are the ancestors of Wajima, and it seems that they are called Ezo people or red deer people, but the real Japanese aborigines were artificially eliminated (extinct) in the subsequent historical development.

Just before the return of the Northern Expeditionary Army. The fleet of the Han Kingdom has made more than 100 sea voyages to Wajima, and the Han troops that have landed have established more than a dozen bases along the coast of Kyushu Island.

The Han army's naval routes are miraculous, as there are several routes in Lü Zhe's memory that can safely travel from the mainland to Wadao during the non-typhoon season, and the first discovered naval route was in the waters of the Korean Peninsula. That is, the route of modern Jeju Island, and the second route that was discovered was the route from modern Ryukyu Island to Sikoku Island. Lu Zhe originally had the mentality of giving it a try, but the route was really explored. That's why there was a follow-up landing.

At present, Lu Zhe's main focus is on the merger of internal countries, followed by the war outside the Seychelles, and he does not have much energy to pay attention to Wadao at all. His instructions to some of the relevant personnel were to send professional prospectors to the island in search of all kinds of minerals, and those professionals were protected by the Han army throughout the process.

The main direction of mineral exploration on the Wajima Islands is to concentrate on Kyushu Island, where the first landing is made, because the landing time on the island is not long, and most of the bases are built on the seaside, so there is not much progress so far. However, Lu Zhe was not in a hurry at all, he was very sure that he would be able to find rich gold and silver mines on Wajima, after all, there were too many records about Iwami Silver Mountain, Sado Gold Mountain, and Fuji Gold Mountain.

The gold and silver reserves of the Wa archipelago were astonishingly rich until the 16th century, and since the mainland of China had trade with Japan, the Central Plains Imperial Dynasty accounted for 65 percent of the country's total gold and silver from the Wa islands. It is no exaggeration to say that until the discovery of the Americas, Wajima accounted for 40% of the world's silver production at that time, and it was gradually depleted due to overmining during the Wajima Sengoku period and the shogunate period.

Lu Zhe naturally has his reasons for setting his sights on the sea, whether it is the Han State or the imminent empire, the use of copper as a material of currency alone will definitely form a deformed monetary consequence, and the monetary reform of gold, silver, and copper is imperative, so having enough gold, silver, and copper is a prerequisite for monetary reform.

Wadao can obtain a large amount of gold and silver, and many islands in the Philippines can obtain unimaginable copper, which is the plundering target that Lu Zhe can think of at present, and it is also the best plundering target, after all, there is no state form of existence in the two places, and there are a large number of indigenous people in the two places, relying on the combat power of the Han army to carry out population captivity and become slaves, don't there be ready-made labor forces? Then, as long as there are enough ships in demand, a large amount of minerals will be continuously transported back to the mainland from the sea.

In addition, Lu Zhe also has a deep intention to do that, nothing can arouse the desire for development more than plundering wealth~ hope, when people find that there is amazing wealth on the sea, there is no need for official urging, and the people will begin to move their eyes to the sea, once they find the richness of the sea. Then the Age of Discovery will also be opened by the Chinese ethnic group.

Because of the direction of plunder, Lu Zhe has recently consciously reduced the amount of local minerals extracted, which is a kind of self-protection measure that many countries have in modern times, that is, they can plunder and never produce themselves, and they can trade to obtain absolute mining.

Lu Zhe firmly believes that the country will be stronger than ever before in his generation, so it is natural that he should accumulate more things for future generations. It is with this idea in mind that he keeps his eyes on the sea while not giving up the surrounding area, such as Jiaozhi, which also has a large number of mineral resources, including Inner Mongolia and Outer Mongolia.

Of course, Lu Zhe is also very aware that this practice will bring inconvenience to transportation. However, in many cases, this is not a bad thing, and the need for transportation will lead to a considerable number of industries, and for an empire with a large population, transportation alone can generate countless jobs, not to mention the construction of roads because of the need.

The construction of roads is a beneficial and harmless thing for the country, and it is always better to build roads under the premise of convenient transportation than to build them because of simple national defense needs, isn't it?

“…… The construction of the road from the Central Plains to the grassland can be planned for five years, during which more Central Plains leaders can be hired, which will also promote public security and stability maintenance. Xiao He was standing in front of a huge but hanging map of mountains and rivers, and his hand kept moving on the map of mountains and rivers when he spoke, and when he moved his hand to the northwest, he continued: "There is already a straight road here, and this straight road is from Xianyang to Jiuyuan......"

The time period when Daqin built the straight road was when Lu Zhe came to this era. He himself was personally involved in supervising the construction of the straight, which in retrospect seems to have been yesterday.

In fact, in addition to building straight roads, the Qin State will also build another kind of road, which is a road called Chidao, which is the highest state-owned highway in Chinese history. The construction of Chidao is a product of the extension of "car on the same track". Many of the roads were repaired or expanded on the original old roads, which shows that the Qin State was well aware of the importance of smooth roads to the country, but unfortunately, whether it was the original historical version or this version of Lu Zhe. Daqin's construction of Chidao has not been able to meet expectations.

The country under Lu Zhe's rule inherited in some ways the inheritance of many countries, and the inheritance did not refer to the wealth of precious metals, but to the original foundation of the road.

Regarding the construction of national highways, the Han State has been building roads south of the Yangtze River for seven or eight years, the first to complete is the road in Qianzhong (Cangwu County) in Nanjun, followed by the galloping road from Nanjun to Hengshan County, and then because of the need for Lingnan conquest, huge manpower and material resources have been used to build routes to South Asia, but so far many roads have not been completed.

Lü Zhe included all parts of the Central Plains under his rule, and compared with the weak foundation of the south, because the Central Plains was an area where the Chinese ethnic group had inhabited for thousands of years, the construction of many places was more mature than that of the south. Because most of the people were displaced during the war, they wanted to maintain law and order while also centralizing the management of most of the people, and there was plenty of labor under the employment of official acts, and it was always before there was no problem with the transportation of grain and straw, and the main construction of the labor hired in various parts of the Central Plains was concentrated on the roads and rivers.

Relying on the good foundation of the old Central Plains and the Qin state, Xiao He's report to Lü Zhe was that road construction plans would be more rapid in the Central Plains than in the South.

"That's right, one is empty, everything is starting from scratch, and the other is already a ......foundation," Lu Zhe nodded constantly, emphasizing: "But we can't stop building because of the difficulties in the south." ”

Xiao He naturally understood.

Because of the beginning of the development of the south, and also because of the early appearance of the two crops of rice, Xiao He, as the ruling officer, knew very well what it meant for the construction of the south. With the results of the construction of the southern counties, we can already see the shadow of some areas in the south becoming grain producing areas, and it is not against the will to assess that in the future, the grain output of Cangwu, Changsha, Lujiang, and Nanhai alone will be able to feed at least 30 or 40 million people, and that is because there is no premise of comprehensive development.

Lu Zhecai will not tell Xiao He what "the lake is wide and ripe, and the world is full", if it is developed enough, it will be a grain producing area that can feed three or four billion people.

Under what conditions was the expansion of the ethnic group based? In the Cold Weapon Age, expansion depended on population, but the prerequisite for having enough population was that there was enough food. Lu Zhe already has a relatively complete plan in his heart, that is, to invest as little as possible in the development of the south, increase the food output of the ethnic group, and then encourage childbirth, if the total population of the Chinese ethnic group can exceed 500 million within 20 years, with the early expansion case, at that time there may no longer be a need for him to rack his brains to drive, because the need for living space, even if he loses his guidance, the ethnic group will try its best to expand outward, in order to seek a larger habitat.

"Your Majesty, there is already an eyebrow about your order to search for saltpeter and brimstone. Our fleet found a large island covered in black sand and dust, I wonder if it was Iwo Jima you were talking about? ”

"Oh?! Already found??? ”

It was time for the Han ships to scurry around on the sea, after all, the first compass had appeared, and the only obstacle to being able to discern the direction on the ocean was whether the ship was strong enough.

In the past few years, Lu Zhe has set up four shipyards along the coast, because there are examples of transportation to the north by sea, the military has also become interested in conquering the sea, and is naturally willing to increase investment, many nobles do not know what the psychology is, seeing that Lu Zhe attaches great importance to the sea and follows the trend, there have been several alliances or a family nature, and shipyards have also been opened along the coast, dedicated to the study of marine ships.

Private shipyards may not have a long-term vision, and many simply want to win orders for shipbuilding from the state, but that is what Lu Zhe is happy to see, and naturally it is convenient in relevant policies.

"In addition, our exploration team has found a new landing site in the north, which is about fifty miles west of an area known locally as the Tsushi region."

"Point it out on the map."

"No!"

Lu Zhe got up and approached, and was a little stunned at first glance. If he remembered correctly, the location of Sima Xin's finger was the modern Lushun, right? (To be continued......)
