Although the extent of each tribe's reserve is large, these reserves are still much smaller than the vast grasslands, and the total area of these reserves is only about one-third of the entire grasslands. www.biquge.info And each reserve is not connected to each other, so that the collusion between the various tribes is eliminated, and each tribe can only live in its own reserve, once it crosses the border, it will be pursued by the Han patrol cavalry stationed on the grassland.

And because there were no horses, it would take several days to walk from the reserves of one tribe to the reserves of other tribes on foot, and it would take almost years to cross the entire grassland.

The Han army did not deliberately designate barren and barren grasslands as reserves, but on the contrary, the areas with abundant water and grass and fertile land would be prioritized as reserves, which undoubtedly relieved the leaders who were very worried about their tribes being divided into desolate areas, and greatly eased their resistance to the reservation decree.

Two-thirds of the steppe, since most of the area belongs to the Gobi Desert, this part of the area is classified as a no-man's land and no one is allowed to enter. The forts and strongholds, which were built between the various reservations, were usually garrisoned by Han troops and Han Chinese, and were also forbidden to the Hu people.

The food and salary expenses of these garrison troops are provided by the taxes of various tribes, and they can also be completely self-sufficient, without the need for the imperial court to allocate money, and only in the case of famine and disaster years, the imperial court will urgently allocate some disaster relief grain and grass to the grassland.

In order to increase the proportion of Han Chinese on the grasslands, Liu Yin suggested that the imperial court reduce the death penalty, except for the most heinous crimes of rebellion, and the sentences of ordinary condemned prisoners would be commuted to life exile, and the prisoners who were originally exiled to the south would also be exiled to the northern grasslands.

This alone could add tens of thousands of Han Chinese to the grasslands every year, and these exiled prisoners could engage in farming and animal husbandry to survive. Those prisoners who were exiled for the rest of their lives could marry and have children, but their children and grandchildren could not leave the steppe for generations.

Liu Yin wants to change the proportion of ethnic groups on the grassland through this means of grassland migration, on the one hand, to curb the development of the Hu people, on the other hand, to support the migration of the Han people, of course, the living environment on the grassland is much more difficult than the Central Plains, ordinary people are unwilling to move in, Liu Yin can only use the brains of prisoners, for those prisoners who are pending execution, exile to the prairie is already a great gift, not to mention that this is a compulsory means, they have to from.

As for the life on the grassland, although it is more difficult, the Hu people can survive, not necessarily the Han cannot, and with the support of the imperial court, it is not difficult to provide them with as much life and production guarantee as possible, so that these exiled prisoners can survive on the grassland.

This will be a long-term national policy, although unswervingly implemented for a long time, Liu Yin believes that in a few decades, it will inevitably achieve fruitful results, and only by completely changing the proportion of the population on the grassland can we truly solve the problem of the northern border.

The only way to solve the problem of the northern border is to attack and defend in the past dynasties, and there is no need to say much about defending, and the Great Wall built by hard work and money is almost impossible to effectively resist the iron cavalry roaring down by the Hu people, and the passive defense is only the part of being beaten.

But even if it is as strong as Emperor Wu of the Han Dynasty, although it can seal the wolf Juxu and go straight to the North Sea, but due to the lack of effective occupation of the grassland, those defeated Huns will soon recover and make a comeback, even if they use genocidal means, it is difficult to cut the grass and eradicate the roots, such a vast grassland, only one or two branches remain, and it will always be strong and develop in the future, threatening the Central Plains Dynasty again.

As for using Hu to control Hu and inciting fratricidal fighting among the Hu people, that is even more of a stupid means. As everyone knows, in a wolf pack, in order to compete for the position of wolf king, countless male wolves will fight to the death, killing each other, and the real final winner is the strongest Venerable. Relying on this bloody killing to ascend to the throne of the grassland, they are often the strongest characters, and after this kind of character dominates the grassland, it will have a fatal impact on the Central Plains Dynasty, such as Tuoba Jue, such as Yelu Abaoji, such as Wanyan Aguta, such as Genghis Khan, they are all heroes who have fought a bloody way out of the bloody tribes of the grassland, they can not only dominate the grassland, but also enter the Central Plains, and it is just a joke for them to control Hu with Hu.

The only way to solve the problem of the grassland is to adopt the colonial methods of the Americans in later generations to change the population ratio of the western region step by step through a large number of immigrants and massacres of Indians. At that time, the western part of the North American continent was a large canyon and a desert, and in terms of natural conditions, it was not as good as the Mongolian steppe, but it only took the Americans one or two hundred years to completely solve the western problem.

The road that Liu Yin took was indeed an unprecedented road, whether it was Emperor Wu of Qin, who lived in front, or Emperor Song of Tang who lived behind, he did not provide him with anything useful, Liu Yin could only use his own way to conduct experiments and explore a feasible path of long-term peace and stability.

As for this process is extremely long, perhaps in Liu Yin's lifetime, he may not be able to see results, but Liu Yin believes that only his method is correct, and after several generations of efforts, it may not be a dream to completely eliminate the border troubles from the north, and the Chinese nation will not have to experience the catastrophe from the Hu people from the north again and again.

Perhaps, this will be the richest legacy that Liu Yin has left to future generations.

Liu Yin went all the way north from the Wolf Juxu Mountain, came to the shore of the North Sea, the North Sea of the Han Dynasty, later generations called Lake Baikal, the pearl of the steppe is the world's largest lake with fresh water storage, the fresh water here accounts for one-fifth of the total amount of the earth, the earliest contact with the Han people in the North Sea is Su Wu, he has been shepherding sheep here for 19 years, unswerving, and Liu Yin has also become the second Han general to really set foot in the North Sea after Huo Qu's disease, picking this pearl is Liu Yin's biggest dream.

The submission of the Xianbei tribes has left Liu Yin without any opponents in this grassland, and Liu Yin went all the way north to hunt wild horses.

If you want to really curb the development of the Hu people, you must solve the problem of horses, and a simple ban on horses can not solve the problem.
