Datang, Hanhai Prefecture.

As the first governor of Hanhai Prefecture, Tian Meng told the truth, life was still very difficult.

Although the Tang Dynasty has plans to establish a city in Hanhai Prefecture, most of the area is still in a traditional nomadic state, which is different from Qinghai.

Qinghai has Hehuang Valley land that can be cultivated, but except for a small part of the land in the entire Hanhai Prefecture that can be cultivated, most of the land cannot be cultivated, and can only be grazing.

It is not that crops can grow where grass can grow.

Moreover, according to the information given by His Royal Highness, the grassland of the entire Hanhai Prefecture is actually very fragile, and if it is not properly managed, I am afraid that it will completely become a desert in the future.

Therefore, the future plan of the entire Hanhai Prefecture is to concentrate the main population in the north, east, and south directions, and further west is not the scope of Hanhai Prefecture.

Of course, at present, the current area of Hanhai Prefecture is also a little too large, and it may be possible to redivide it in the future, but now, it is not.

At present, the main construction site is Hanhai City (later Ulaanbaatar), as well as several small cities stretching to the south, and further north is Beihai City, Beihai City is located on the edge of Beihai, which is the largest freshwater lake in the north, surrounded by mountains and forests, but the climate is very cold.

This place is winter most of the year.

However, with Datang's current technology, especially after the large-scale use of wool, it is not difficult to live here.

In addition to this, the widespread popularity of fire walls, and the creation of high-yielding crops such as potatoes allowed them to feed large populations here.

The main task of Hanhai Prefecture in the past two years is to find out the road to this area, and then plan the route reasonably, and then to gather out the primitive tribes in the surrounding mountains, and then to move the boundary monument of the Tang Dynasty to the north as much as possible.

However, on the map, the borders of the Tang Dynasty have reached the northernmost Arctic Ocean, as His Royal Highness calls it. It is said that half of the year is daytime and half of the year is night.

Not to mention, after more than a year of exploration, there are not many primitive tribes in these places.

Under the strong co-ordination of the nomads, these primitive tribes naturally integrated into the Tang Dynasty smoothly, and even the nomadic tribes lived so miserably, not to mention these primitive tribes.

In the past two years, the whole Hanhai Prefecture has changed the most, a large number of herdsmen have been arranged as a whole, and after reasonable arrangements, each family can graze more cattle and sheep, and the real grassland is different from that of Qinghai Prefecture, and each herdsman is allocated about 3,000 acres of grassland.

All the allocated pastures are high-quality pastures in the eastern part of Hanhai Prefecture.

This was a decision made by Li Ke, and the current jurisdiction of Hanhai Prefecture is probably Mongolia in later generations, plus the area around Lake Baikal and the central region of Inner Mongolia.

Including the later generations from the nearby grasslands such as the Siziwang Banner in Hohhot all the way to the east, Xilin Gol Grassland, Paradise Grassland Ulagai, East Wuzhumuqin Banner, West Wuzhumuqin Banner, until it was close to the border of the Xing'an League, and then all the way to the north.

In the east, the later Arshan, as well as the Daxing'an Mountains and the Hulunbuir Grassland, will be divided into the eastern Murwei Prefecture.

These grasslands are excellent grasslands for future generations, let alone in the era of the Tang Dynasty.

There is still a big difference between the Tang Dynasty in the north and later generations, for example, in the Hetao area, the Mu Us Sandy Land in later generations has been vigorously governed, and there is still a vast desert, but in this era, it is still rich in water and grass.

However, there are already a few areas showing signs of desertification, and if grazing in these areas is stopped at this time and the population is moved out, there is a high probability that the place will return to its original state, but if it continues, it will gradually become the future in a thousand or two thousand years.

Similarly, the Saihan Dam in later generations was still dense and handsome in the primeval jungle during this period.

In the future, the beautiful paradise grassland Ulagai, now you can really see the scene of cattle and sheep in the wind blowing grass. In the later generations, the Xilamuren grassland north of Yinshan in the north of Hohhot, which is the north of Wuchuan, the current military town of the Tang Dynasty, is now a piece of green, and the grassland can reach people's knees.

More than 1,000 years later, the Xilamuren grassland is almost desertified, and the grass in summer cannot even grow to the ankles, which is caused by overgrazing.

In fact, the reduction in precipitation in the Hilamuren steppe has an inexplicable impact on the dramatic environmental changes in northern Mongolia. So now Li Ke has designated almost all of Mongolia's western part as a fragile ecological nature reserve.

And these high-quality pastures have been strictly calculated by later generations, and there is no problem in feeding five sheep per acre of pasture, which can be easily competent, and does not damage the water and soil.

If it is a cow or a horse, one acre of land can probably support one cow, or two horses. According to this proportional reduction, this will be the sustainable development strategy of Datang on the grassland in the future.

In other words, theoretically, these herders could raise up to 4,000 sheep per household, a number that would not have been imagined for herders at this time.

Of course, for the time being, Datang has not yet announced this policy, but the sustainable development of grasslands and the conservation of soil and water in grasslands have begun to be taught to all herders.

In fact, these herders seem to be uneducated, but they can understand and listen to this knowledge. Because generations of herders know very well that the grassland is their greatest capital and their hope for survival.

Therefore, the herdsmen hate the destruction of the grassland the most, they just didn't understand the truth of the operation of this heaven and earth before, but now that Datang teaches them, of course they are willing to listen.

It can be said that although Xue Yantuo and other surrounding areas have been completely attached to the Tang Dynasty for a short time, what these herdsmen have felt is unprecedented, and now you let Zhenzhu Khan Li Yinan come back here to rule them, and the herdsmen here are estimated to be able to pull out their swords and cut them back.

It is precisely based on this state that Tian Meng has some distress now, because around Hanhai City, there are now more and more herdsmen gathered.

These herdsmen are from the subordinate tribes, although these herdsmen are currently attached to the Tang Dynasty, but here temporarily retains the title of the ministry, in Hanhai Prefecture, the ministry is equivalent to the village. There is no reform in the townships, counties, and counties above the tribes.

And these herders from various tribes have only one demand...... That is to fight for His Highness.

"Governor Tianmeng, you make a decision, they have to fight for His Highness, according to the statistics from the outside now, I'm afraid there are nearly 100,000 people, according to them, this is the tradition of the grassland people, His Highness gave them a new life, they have to work hard for His Highness, since Goguryeo dares to provoke our Tang Dynasty, they will go to kill the Goguryeo people." Cui Liang, the general of the Hanhai Prefecture garrison, said helplessly.

"You think I don't want to, the problem is that His Highness has a death order. No ordinary person is allowed to participate in the war without permission. Tian Meng was a little helpless.
