Liu Yan wants to have a larger population, relying solely on the womb of a Han woman to increase the number of people, and that speed will be really slow.

If you really want to maintain the purity of the bloodline, with the number of Han ethnic groups after the establishment of the Han State, the population will be nearly 10 million, and if the mixed-race children are recognized as Han Chinese, the number of people will definitely be reduced again.

Calculated in terms of a population of 10 million, not everyone is at the age of childbearing, and the number of women who can give birth will not exceed 1.5 million at most.

At the same time, not everyone of the 1.5 million women who can get pregnant can safely give birth to their babies under the current sanitary conditions and the current level of technology.

Not everyone can grow up healthy, and at today's general rate, only about six out of ten babies will eventually reach adulthood, which was a common phenomenon in ancient times.

It takes at least thirteen or fourteen years for a person to become a new reproducing individual from birth, and each new generation needs a period of growth, which is a very long process.

"The widow can't wait that long." Liu Yan has never hidden his ambitions: "If there is really not enough population, it is an extravagant hope to expand outward." Even if it is defeated, there is no population to use it in the past, so what is the use. ”

The ministers had heard Liu Yan say similar things more than once, including that the current era was the best era for the Han people to expand, and if they did not seize the opportunity in front of them, they would inevitably suffer.

In the late Eastern Han Dynasty, the Han people fought against each other and experienced two large-scale typhoid fevers, and the population dropped rapidly from the official record of 56 million to 7.6 million.

"Success or failure turns empty, the green mountains are still there, and the sunset is red several times." Liu Yan didn't come up poetically, he sat in the car on the road and watched the scenery that kept speeding by: "The mountains and rivers are always there, but the people are generation after generation. ”

If you really look at the pedigree, it is unknown whether the population of the Han State established by Liu Yan can exceed 10 million, and it will take about fifteen years to have a group of people who will become a labor force, which is something he cannot accept.

Then there is one thing, the ancestors of Zhuxia were so many people at the beginning, they absorbed and fused the defeated tribes in the process of continuous conquest, and slowly made their own tribes grow, if they confirmed the ethnicity purely by blood, no one including Liu Yan dared to say that the bloodline on their body was the bloodline of the first generation of Zhuxia.

It is said that it is Zhuxia, which means that it is the combination of multiple ethnic groups and produces a sense of ideological identity in the form of culture.

A nation must not give up merging and integrating with other nations, and that is actually the right way to increase the gene pool.

To put it simply, siblings or siblings must not be combined, and it is not to reject incest at the beginning, but to understand that the offspring born will have various genetic diseases.

The difference between humans and animals is that they will make changes when they know that they are wrong, and animals will repeatedly combine with each other to produce offspring, because the intelligence of animals is just like that, unless there are obvious physical defects, or it is difficult to see whether the intelligence is up to standard, but people are really different, no one wants their offspring to be a retarded.

The patrol team had turned back and walked the road line from Gaoxian again, and their destination this time was Ma Shijin.

Liu Yan's inspection on the Northeast Plain lasted for a total of five days, and he roughly inspected several places, so it was enough to have an intuitive impression of the local area, and he would not go deeper into the north or east.

Unlike other parts of the Han Kingdom, snow begins to fall in autumn, and the ground should be covered with snow and ice near the middle of autumn.

Liu Yan's trip to the grassland was delayed because of an enemy attack, and he was trapped by ice and snow in the northeast, although both were forced to stop, but the two are really not the same thing.

Compared with being involved by the enemy army, there will be more uncertainty about the difficulties from nature, at least those enemy troops will not pose a real threat to Liu Yan, even if they can't handle it on patrol, they will move back over time, and countless Qinwang troops will rush to reinforcements.

Nature is not something that people can resist in many cases, and if there is a sudden snowstorm, there will be cold preparedness and death and injury will inevitably appear, and if you want to open a way out, you really don't know when.

Coincidentally, as soon as the patrol team returned to Gaoxian, there was news of a sudden snowstorm there, and no work outside could be done, and traffic was cut off.

"The Prime Minister's Mansion has already carried out the work of transferring slaves in advance." Lu Tai will follow Ma Shijin before returning to his work again: "Your Majesty saw some time ago that it was one of them. ”

After the snow season, there is nothing else to do in the Northeast except for Maodong, so the Han Kingdom will not leave so many slaves idle to do.

Slaves staying in the Northeast not only caused waste, but also a waste of both materials and labor. After all, slaves cannot be allowed to freeze to death and starve to death, the additional clothing must be added, and then it must be burned every moment, stoves, large kangs, bonfires, etc., even if local wood is everywhere, all that can be consumed is wood stored in advance, not wood that is frozen by ice and snow to the point that it is difficult to burn.

Han is now extremely short of labor, and after the snowfall season in the northeast, development will inevitably come to a halt. Sending slaves out of the Northeast to places where it also snows but is not as bitter as Northeast China, and even going to places where it doesn't snow at all, and continuing to shine is what those slaves should do.

In fact, Gao Xian went to Zhuoxian, Gao Xian went to Ma Shijin, and the two gallops were transporting people and goods to the mainland every day.

The gallop invented by the first Qin Dynasty is easy to use beyond imagination, and the speed and loading capacity of the vehicle may not be more and heavier, but compared to simply rushing with two legs, or traditional horse-drawn carriage transportation, it seems to be faster and more cargo-bearing.

"It took more than two years to build these two gallops, and more than 200,000 people were killed and injured." Sang Yu also inadvertently read the relevant documents: "There are enough timber resources in the local area, and if it is replaced by other areas, it will take longer, and there will be more casualties." ”

There is never an easy time to build a road, there are still special surveyors to designate the route, and it will be more difficult if you don't know how to choose the route to build a road.

"More than 50,000 slaves died on the road from Zhuoxian to Gaoxian alone, including those who are disabled." Liu Yan attaches great importance to the Chi Road, how each Chi Road was built, and how many costs and casualties were incurred in the construction process, he personally checked the information: "That is still the premise that we cherish the lives of slaves." ”

Liu Yan remembers a lot of information about road construction.

In order to build the road to Shudi, Li Tang dug the plank road and sacrificed thousands of people one after another, and it can be regarded as a completion after several generations, and the casualties should be counted as hundreds of thousands.

In modern times, the Chinese traveled across the ocean to pan for gold, but the gold was not found, it was sent in batches to build various roads, and it was not a joke that there was a Chinese corpse under every sleeper on the North American railway.

The galloping road from Gaoxian to Mashijin that they are using now takes more time than the one from Zhuoxian to Gaoxian, and the casualties are also heavier. That's because the terrain on this side is more complicated, and several of the sections have to be opened, but fortunately there is gunpowder, otherwise I don't know what year of the monkey will be repaired, and the casualties will definitely be several times more.

The first time Liu Yan set foot on Ma Shijin was before the establishment of the Han Kingdom, at that time, they were forced to evacuate Changguang County, or they went to the Miaodao Islands to respite, and later found this place of cultivation and recuperation on the Liaodong Peninsula.

Mashijin is actually the modern Lushun, and there is a natural deep-water port on this side, which can be very convenient to build a port. It not only has a natural deep-water port on this side, but also has a ring of arms on the periphery, leaving only a passage for ships to enter, as a military port can be more likely to avoid a sudden attack by enemy ships on the surface, but if it is blocked, it is not easy to get out, which is considered to have advantages and disadvantages.

To enter the Liaodong Peninsula, the patrol team first had to pass through a city wall that stretched for more than ten miles. The reason for the establishment of this city wall was that Murong Yan Kingdom came to attack at that time, Liu Yan did not have many troops at that time, and he gritted his teeth to build a city wall defense line with few resources, which also made Murong Yan's army feel that the cost of a strong attack was too great and chose to retreat.

Liu Yan used the system to build the city wall defense line is also this place, and then it is used to build the palace city, such as the palace city wall of Linzi and the new Chang'an, in fact, it is built by using the system, not a rammed earth structure, but a stone material.

Now that the Murong Yan Kingdom has been destroyed, although there are still remnants of Murong, it is too far away from the Liaodong Peninsula. Including Liaodong and other places and the peninsula are all Han soil, the city wall of the Liaodong Peninsula actually has no great military value, only garrisoned 500 people as symbolic meaning.

After entering Liaodong, you can clearly distinguish the difference from the northeast, you can see the villages and towns, but it will still be much more desolate than the mainland.

"There's a lot of snow in the Northeast, and it's only raining here." Yu Yi didn't understand what the phenomenon was, and he hadn't actually been to the Liaodong Peninsula: "The two places are not far apart, but they are two scenes. ”

Liu Yan has personally experienced more than once that it is raining on one side, but there is not a drop on the other side without taking a step, and he doesn't think there is anything strange.

When they entered the Liaodong Peninsula, all they saw was prosperity.

At its peak, the population of the Liaodong Peninsula was nearly one million, and although it was not a single city, you could see villages and towns everywhere, and of course there were farmland that had been carved out.

Today, the population of the Liaodong Peninsula is still more than 500,000, which is one of the most populous administrative regions in the border region, and most of them still followed Liu Yan when he was down, and there is no shortage of some meritorious family members, and they also regard themselves as the confidants of the Son of Heaven.

Liu Yan went out to patrol to this place, the people were thousands of empty alleys to greet him, the entire station, including the surrounding area, at a glance to remove people or people, and the slogans shouted one after another.

"Your Majesty." After Su Le, I looked already old, and I was elected as the representative of Liu Yan to meet Liu Yan, dressed in a costume: "Your Majesty is here again after eight years." The old man finally saw His Majesty again. ”

Liu Yan had actually forgotten who the person in front of him was, firstly, he was not impressed by Su Lewan, the patriarch of the Qiang family who was the first to be accepted in Changguang County, and secondly, there were too many things to deal with every day, and it was really difficult to remember everyone clearly.

Of course, Liu Yancai would not clearly say that he didn't know him, but smiled very kindly and asked how he was doing, how many children and grandchildren he had, and so on.

"I have a good life, and I have many children and grandchildren, all of whom are working for Your Majesty." After Su Le, I also specially mentioned Su Dong, the county guard of Liaoxi County, saying that he was his eldest son, and he had seen Liu Yan more than once when he was a child. He mentioned a few more later, either as a magistrate or in the army, as if the whole family was working for Liu Yan: "The old man is old, so he will retire here." ”

Liu Yan remembered that this family was originally a Qiang family, but it was also a Qiang tribe that was almost sinicized, and it was one of the families that he took the initiative to come over when he started. His next thought was that there were six people in the family who served as local officials, and the most outstanding one was the county guard of a county, and the worse ones were also important positions in the county, not to mention that there were four other people in the army, and the highest position was the captain, which could be regarded as an official eunuch's family.

Their nature is Su Le, and they have changed to the surname Su, and they will not be the best mixed family after the alien race becomes the Han people, but they also look quite good, there are not many naturalized Han people like the Su family, and the best mixed among the naturalized Hu is Qian Jiantong, who was originally a Hun person.

The welcoming ceremony ended quickly, and then there was an official-led carnival, and Liu Yan definitely wanted to participate in it, even if he pretended to be a hero and treat the people of the dragon with kindness, otherwise there would inevitably be a taint of being mean and unkind.

The Han Kingdom has naturalized Hu mixed heads, but it accounts for a small proportion of them, the center is only about 99.9 percent of the countless nine, the middle level is about 10 percent from the naturalized Hu but mixed up about 10 percent, and the grassroots level will reach about 20, in fact, the real right to speak is still in the hands of the ancestors is the Han people.

At present, there is only one ethnic group in the official household registration of the Han State, and those who are not Han in the household registration will definitely not be able to participate in the system, Liu Yan does not need to engage in the project of ethnic minorities for the international community, and he deeply knows that the purer the division of the people in the ethnic group, the better.

After getting on the ship, Liu Yan especially asked people to find Su Dong's resume, and at a glance, Su Dong's ability may not be outstanding, but it can be regarded as the type of loyalty. He looked at the resume of another Su Bei, who had become a school captain, much more beautifully.

"There are seventeen direct clansmen of the Su family who died in battle, and there are even more ...... side branches" Liu Yan is actually jealous of the official eunuch family he did, and he knows very well that all the official eunuch families can become a family or even a gate valve at any time: "No matter what the future generations are, at least any generation of pioneers will have to pay." ”

If you have worked hard for most of your life, but you have not created any value, even if you have created something, it will not be helpful to future generations, so what is the difference between living in vain?
