There are two lakes, one large and one small, and there are rivers between them, so they are called Mandarin Duck Anchor.

The harvested wheat fields by the lake are sparsely stubble, mixed with a large number of weeds, and a few scattered herds of cattle and sheep are grazing on the harvested wheat fields with some green weeds. The same is true for alfalfa fields, where the amount of grass planted in the first year is only half of the normal grass yield, and the density needs to wait until the third year to reach the peak yield.

An Shouluan rode over from a distance, and when he saw Liang Xing, who was directing his subordinate Tuntian military households to repair and dig a canal, he smiled and said, "How is this year's harvest?" ”

Liang Xing sighed in his mouth and replied: "There are less than two stones in one acre of land, which is almost enough to feed yourself." ”

An Shouluan smiled: "It's already a lot, I heard that it's not bad to harvest one stone per mu in the raw land." ”

Liang Xing said angrily: "What you said is a dry field, but I am watering the ground." I somewhat understand the meaning of the Son of Heaven not to allow the cultivation of dry land, and in most places in the northland grasslands, growing crops is actually not as good as growing grass. ”

Because of his military exploits in the Xinghebao Army last year, Liang Xing was one of the first batch of his classmates to be promoted to the position of commander of the Tuntianwei. This Tuntian commander is the martial arts of the eighth grade, which is equivalent to a county and county.

The rank of officers and generals of the Northern Army also continued the nine-grade system of the past, but it was divided into nine grades and twenty-seven levels, each of which was divided into three levels: positive, subordinate and attached. After the level is subdivided, it is easier for everyone to be promoted than in the past, there is no merit, and you can get promoted if you have enough qualifications, and there is hard work without merit.

An Shouluan continued: "Wu Zhenfu has sent us to count the difference between the rations of each Tuntianwei, so that we can apply for a subsidy from above, and let your Si Cao make the table and prepare to submit it. ”

Liang Xing said: "This is not necessary, there are two alkali pools in my jurisdiction, and we can exchange the insufficient part with the Chamber of Commerce." ”

An Shouluan said: "One yard is one yard, the income of the alkali pond is another matter, the above means that it is used as a development fund, and the harvest of Tuntian is insufficient, and it is necessary to apply for subsidies." ”

In autumn and winter, the grassland is desolate after the leaves have withered.

The importance of Beidi Tuntian has been told to them many times.

Only when the border land is abundant and the products are abundant enough to be self-sufficient, can the passive strategy of the Tang land against the Khitan on the grassland be completely reversed. At least until then, when the army goes out to the Northland grasslands, there is no need to worry about the supply of grain and grass. In fact, the logistical problem has always been the most difficult problem to solve because the Central Plains Dynasty was unable to completely control the grassland.

A cart of grain and grass is transported from the Central Plains to the grassland, and more than half of it will be consumed by the transportation team on the way.

Emperor Yang of the Sui Dynasty once tried to solve the problem of food consumption during transportation by transporting troops to the front line and turning them into soldiers, but in the end, the number of troops on the front line accumulated more and more, resulting in the collapse of the million-strong army due to the lack of logistics supply during the expedition to Goryeo.

The Bashang grassland was undoubtedly the frontier to prevent the westward expansion of the Khitans, so the Tang army began to build a series of Tuntian castles around rivers and lakes here.

For the Khitan, Li Qi has always maintained a high degree of vigilance, even if the war in the south is urgent, he did not send the cavalry troops in the Bashang, Yunzhou, and Hetao areas to the south.

In terms of combat experience with the Khitans, the combat ability of the elite Hedong cavalry is obviously stronger than that of the Khitan elite cavalry units, but the garrison is far behind in this regard, and it is impossible to resist the invasion of the Khitan cavalry without the help of fortresses and cities. Therefore, in Tuntian, in the north, it is still a result fortress promotion policy.

In each of the Tuntian guards, a strong fortress was built.

On the whole, Li Qi did not think that his strength would be worse than that of the Khitan now, but because the south had not yet stabilized, he did not mean to win a decisive battle with the Khitan first, but continued to adopt a conservative defensive strategy. Because he firmly believes that as time goes by, his strength will become stronger, and the comparison of strength with the Khitan will become more and more favorable to him.

The knowledge structure of the traverser itself has an absolute advantage over even the wise and resourceful figures of the ancient and modern times, and those Hanchen who worked for the Khitan are not extremely intelligent people.

This belongs to the rolling of the plane, as long as you don't forcibly lower your IQ to the level of your opponent, you have to be the battlefield with the opponent. The advantage of the traverser lies in knowledge and wisdom, in production and construction, and in invention, rather than fighting the enemy on the battlefield.

For such mentally retarded behaviors as competing with Yelu Deguang for riding and archery, Li Qi would never do it.

The biggest advantage of Huaxia for the world is that it accounts for nearly one-third of the world's population. However, when it arrived on the grassland, the long distance and huge logistical pressure made it impossible to give full play to its huge military superiority, and all of it was wasted on the road of grain and grass transportation.

It is not that in ancient times, the policy of military reclamation and border reclaiming was not implemented, but unfortunately, because of the contempt for scientific production technology, these policies were never well implemented.

Li Qi stayed in Cizhou until it was almost winter, and then set off to return to Jinyang.

Cizhou, Xiangzhou and Xingzhou were all places with more iron production in the Tang Dynasty, and it was precisely because of the existence of the Cizhou Iron Supervisor that the administrative center of the Handan region in later generations was transferred from Handan County to Fuyang City in Cizhou since the Northern Dynasties. These three states are close to the Taihang Mountains and are relatively rich in coal and iron resources, which are very suitable for the development of the steel industry.

Li Qi gritted his teeth and approved the plan of the capital water supervisor to build a reservoir on the Zhanghe River.

This is a big project, and it costs a lot, but after the completion of the reservoir, the flood control and irrigation benefits are not small.

Successfully seizing Hanzhong and opening up the trade route with Shudi, Zhang Jinda's Western Route Army finally achieved results far beyond Li Qi's original expectations.

The total annual transaction volume of silk tea and horses between Sichuan and Beidi is about 3 million, and the profits in it are huge, which is also a major reason why Li Qi is eager to open up the connection channel with Shudi. The first is to suppress the ambition of the Liangchuan Jiedu military town, and the second is to control this huge profit.

Over the years, the tea and horse trade in Shu has been mostly controlled by the big wealthy families in Liangchuan, and Li Qi disdains to do this kind of unskilled thing by using violent institutions such as the government and the army to forcibly snatch food from other people's pots.

His idea for the three major firms, including Zhang Xuan and Li Huan, was to ferment green tea into black tea, then press it into brick tea, and then transport it to the grassland for sale.

Red theophylline has a much stronger ability to decompose oil than green theophylline, and it is easier to store for a long time, so it is more popular with herders on the grassland. In another time and space history, the process of making black tea did not gradually develop until the late Age of Discovery.

As for making brick tea, it is purely to reduce transportation costs.

After all, tea takes up a lot of space, and if it is pressed into brick tea, it can save at least half of the transportation costs......
