The carrying capacity of the grassland is extremely fragile compared with the agricultural area, and in order to prevent the grassland population from reproducing and causing the degradation of the grassland, and the competition for grassland due to population pressure among the territories, the primogeniture system of land should be implemented for both military and civilian populations. The well-developed factory handicraft industry in the main area of Lanzhou will absorb the population that thrives in the grassland territory.

In the discussion of the high-level of the brotherhood, Yu Furenliang and Xin Gudu proposed that the Central Plains Prefecture under the control of Lanzhou would be able to absorb the second sons of these landless steppe tribes as cavalry, but Wu Yingying vetoed them. Pure force will lead to rebellion no matter which ethnic group is in the hands of any ethnic group, and if the Lanzhou system wants to survive for a long time, it must achieve a balance in force between the Central Plains and the grassland peoples, even within a country. The An Lushan Rebellion of the Tang Empire and the rebellion of the Turkic Guards and Mamluk Army of the Middle Eastern Empire all show that it is extremely dangerous to preserve a nation within the country that has served for generations, and that excessive concentration of force is enough to lead to enslavement that cannot be resisted.

There is no distinction between ethnic groups in the professional army, and although the people of the Central Plains Prefecture are now regarded as weak, it does not prevent the emergence of elite armies that are enough to compete with the nomadic army in every era. Moreover, with the widespread spread of grass and livestock, the children of the Han people will have more opportunities to come into contact with high-quality war horses, and the more affluent society will be able to withstand the resources required to train professional sergeants. Therefore, there is no reason to be sure that the Central Plains cannot rely on its own people to build a strong cavalry army. Moreover, Lanzhou vigorously pursued the policy of advocating martial arts, but it was only feared that in any place in the future, the status of a sergeant would be the object of contention by the public, and the number of sergeants in control had a bearing on the rights of all political and economic aspects, and how could the military governments in the Central Plains be willing to hand over a large number of posts to others.

However, Wu Yingying is ready to vigorously expand the Menghu-military government system in the future, and establish a more elite teaching army, which can completely break the geographical restrictions to select the most elite warriors as the core existence of the entire army system. All sergeants are required to train in this central army for a year after obtaining their status, and then return to their hometowns. Thereafter, each officer promoted to the rank of officer is also trained. Since the Lanzhou Army has adopted the system of promoting middle- and lower-level officers, the only way to do this is to intensify the training of officers at all levels, so that they can not only meet the expectations of the people, but also have the ability and character to perform their duties.

With the spring breeze, the snow melted on the grassland, and the climate became warmer, and the Lanzhou hussar camp escorted the caravan to Dunhuang. The commander of the left army, Xingu, was also the commander of this caravan, and this time there were 2,000 people, 500 hussars, and 1,000 crossbowmen to escort it.

Xin Gu staggered and sat on the horse, and the more drowsy he felt, the more the discussion content of Wu Yingying and the others at the top of the brotherhood came to his mind. Sometimes Xin Gu couldn't understand why Wu Yingying, who now only owned one continent, wanted to take these military strategic plans that should have been hidden in his heart to the high-level of the Brotherhood to constantly discuss and refute.

"In order to form a consensus. Wu Yingying once told him this strange word, "With the existence of consensus, we are like a monster with thousands of heads, tens of thousands of eyes, hands and feet, although there is no contact, every part of the Lanzhou army can make the most suitable action in our interests according to our consensus." "The seizure of land power is a consensus reached by the Lanzhou Brotherhood.

Xin Gu shook his head helplessly, the thing that the commander said about the consensus seemed to mean that the general would not be subject to the foreign monarch's life, as if it was faith, anyway, it seemed to be nothing, it was quite complicated. However, everyone's gossip together is quite exciting. The boundless sand dunes are like undulating waves, and the hot winds blowing from the depths of the northern desert occasionally roll up the yellow sand. When the wind was strong, the caravan had to wait in a circle for all the pack horses until the wind eased before moving on. On this desert, the caravan of thousands of people is like a flat boat in the sea, all relying on the Sinan needle and the guide who is familiar with the road to indicate the direction, once lost, can never walk out of this vast sea. Fortunately, this desert trade route has been traveled to Lanzhou several times, and each time it has been done step by step, and there has been no major chaos.

In order to lighten the burden, the hussar battalion escorting the caravan handed over the excess baggage to the tribe at the last stop for safekeeping, and the last leg of the Lanzhou caravan's journey to Dunhuang would be along the seasonal Zhangye River to Suzhou. After replenishing grain and grass again, he arrived in Dunhuang through Yumen Pass.

At this time, it was spring, the melting snow on the high Qilian Mountains flowed down the Zhangye River into the Yanhai, and the Lanzhou caravan traveled all the way to the south against the river, all the way to the oasis, neither worried about the lack of water sources, nor worried about losing the road, but a rare and easy journey.

Gu Tan, the captain of the Shooting Goose Battalion who accompanied the Lanzhou caravan, rode a horse behind the caravan, and the 500 sergeants of the Shooting Wild Goose Battalion carried a total of 100 carts, of which 50 were loaded with baggage, and 50 were for the sergeants.

"The bicycle wants to ask the side, and the subject country lives extends. Zheng Peng out of Hanse, return to the wild goose into Hu Tian. The desert is lonely, and the sun sets over the long river. Xiao Guan rode every time, and they were all protected by Yan Ran. Gu Tan muttered, life encounter Ruosi, two years ago, he was just a young master in Gujiawu Fort in the south of the Yangtze River, because the Qiantang Army ransacked his homeland, he angrily joined the army, who knows that after several twists and turns, thousands of miles to the battle, he has actually achieved the position of captain in this Lanzhou army that is rising like the sun, the man should die in battle, and the horse leather shrouded and returned, only pity the elderly parents at home, I am afraid that they are still looking north in the south of the Yangtze River, hoping that their son will return safely.

The oases on both sides of the Zhangye River are full of people of all ethnic groups, and this place should be the boundary of the Uighurs in the Central Plains, but in fact, there are many of them and even Han people, and the Uighurs are only the largest of them, even if there are tens of thousands of Uighurs, the great khans of Ganzhou and Suzhou can completely control only three or four percent.

The caravans were the most welcome guests of these tribes, because the caravans had to replenish the grain, grass and water in these oasis tribes, and they would purchase the hides and skins of wild beasts hunted by the oasis tribes, the fruit wine brewed, and a large number of exquisite goods from the Central Plains or the Western Regions, and also relied on the caravans to bring them to these tribes surrounded by the desert.

Of course, if it is a lone merchant in the desert, these tribal nomads are likely to buy and sell by force, or even kill people and plunder goods, but a large caravan of thousands of people like Lanzhou, and a large caravan guarded by the army, it is only a matter of an order to destroy a tribe of about a thousand tents, so these tribes and Lanzhou are only doing their own business. Even many tribal athletes, seeing that the Lanzhou army was well treated, asked many times whether to recruit new soldiers.

"Captain Gu, you see that I shoot a good arrow, tame wild horses, and one person can kill three or five horse thieves, so recruit me. Guding pleaded as he pulled a hard bow into a full moon. He was a guide recruited in Juyanhai, originally a tribe on the bank of the Zhangye River, who couldn't hold back in the desert, so he came out to try his luck.
