Ban Chao and Ban Yong saw this, so the father and son followed one another.

With a fearless attitude and extremely high double merchants, they repeatedly took advantage of the contradictions between the countries in the Western Regions to find the most favorable balance for the Eastern Han Empire, maintaining the influence and control of the Eastern Han Empire over the Western Regions and maintaining the smooth silk trade routes.

And they also used the forces of the Western Regions to fight to the death against the Northern Xiongnu many times, driving the Northern Xiongnu one after another, and doing their best to drive the forces of the Northern Xiongnu outward.

However, the snipe and the clam competed, the fisherman profited, and the Eastern Han Empire was declining, and the century-long Han-Qiang War exhausted the national strength before the Yellow Turban Rebellion.

Prior to this, the Eastern Han Empire fought desperately and stabbed the Northern Xiongnu to death with the last sword, and then basically lost his breath, and as a result, the Western Regions countries were liberated.

This is equivalent to two powerful bigwigs fighting each other, and they will die together, and the younger brothers below will be free.

From Emperor An of the Han Dynasty onwards, the Eastern Han government's control over the Western Regions deteriorated.

There was no such excellent leader with strong personal charm and personal qualities as Ban Chao and Ban Yong who could make the Western Regions countries obey, and the Eastern Han government's suspicion of Ban Yong's behavior of asking Ban Yong for guilt also made the Western Regions countries lose trust in the Eastern Han government.

Wang Jing, the governor of the Western Regions, was killed by Khotan, and the Eastern Han Empire could not send troops to conscript.

The new king of the Eastern Han Empire was opposed by the domestic ministers, and the Eastern Han Empire could not stop it.

Shule was in civil strife, and the Eastern Han Empire sent people to conquer it several times, but it could not win or intervene.

After one defeat after another, the prestige accumulated by the Han Empire in the Western Regions from the Western Han Dynasty to the early Eastern Han Dynasty was exhausted.

In this way, in the later period of Emperor Ling of the Han Dynasty, the Liangzhou Rebellion cut off the communication between the Western Regions and the Han government, and after the Yellow Turban Uprising, the Eastern Han Empire could not protect itself, let alone rule the Western Regions.

That is to say, from the seventh year of Guanghe to the current three years of Yande, a total of twenty years, the Western Regions have long ceased to obey the control of the Central Plains Empire.

They have become independent countries one after another, do not obey the orders of the Central Plains Empire, no longer obey their own suzerain, play with themselves, and have a lot of fun.

Happy like a 200-pound child.

The Silk Road is not isolated due to some special necessities, and the economic exchanges are still the same, and there are always business travelers who can magically appear in the two places, bringing their respective specialties back to their respective countries and earning high profits.

In this regard, Guo was very unhappy.

You guys make a lot of money, don't you?

Dare not pay taxes?!

Therefore, after Guo eliminated the warlords of Liangzhou during the Jian'an period, he ordered the Wei army to occupy all the roads from Wuwei County to the eastern part of Liangzhou, and all merchants who wanted to enter the eastern part of Liangzhou and the Central Plains to do business had to pay a lot of tolling taxes.

Then you can't go deep into the Central Plains, you can only trade with the Central Plains Business Travel in the market specified by Hanyang County, and you can't go deeper.

Guo wants to use this to tell the countries of the Western Regions and the Central Plains that there is a new master.

At the same time, Guo also complained about the Eastern Han Empire.

If it weren't for the fact that the Han Empire had left so many messes and asked Guo someone to clean up and wipe his buttocks, Guo would have sent troops to the Western Regions to tell them what it was since ancient times.

Fortunately, however, after several years of recuperation and preparation in the fields, the four counties of Liangzhou have accumulated a considerable amount of grain, straw, ordnance and materials, the rural system has been implemented, the mobilization force at the grassroots level has been basically prepared, and the newly trained 30,000 Liangzhou cavalry are also eyeing up.

Yongzhou, as the general logistics base, was also well prepared under the governance of Chen Gong, with mountains of grain and grass, and the treasury was stuffed with ordnance and supplies and the standard five-baht money as military salaries, just waiting for the start of the war.

After owning the three major horse breeding grounds of Liangzhou and Youzhou, plus the equipment of the three artifacts of cavalry, in a few years, the number of cavalry of the Wei army has expanded from 70,000 before the establishment of the Wei State to 170,000 today.

In the past few years, 100,000 cavalry joined the battle sequence of the Wei army, which greatly improved the mobility and combat effectiveness of the Wei army, and also greatly improved the endurance of logistics.

The addition of a large number of mules and horses greatly improved the Wei army's logistical radiation ability on land.

The Longxi Horse Farm in Liangzhou, the Yanmen Horse Farm in Bingzhou and the Liaoxi Horse Farm in Youzhou have raised more than 800,000 war horses.

At present, this number is still increasing, and it should exceed 900,000 within three years.

As one of the only Jiuqing who is now in power, Taifu Xian Yuyin personally sat in the Longxi Horse Farm in Liangzhou, herding more than 500,000 horses, and gave Guo Peng great help in terms of war horses.

Guo Peng also gave Xian Yuyin a lot of help in the breeding of war horses.

The special funds are earmarked, and the funds for raising horses are specially set up, which are calculated separately from the state treasury and the inner treasury.

This independent war horse fund allowed the Wei Empire's transportation efficiency to begin to take off.

Especially at the military level, the addition of more and more war horses allowed the Wei Empire's army to gallop on the battlefield at a maximum speed that surpassed that of all the armies of its time.

The time savings are incalculable.

Guo Peng placed in Liangzhou and handed over to Cao Ren's commander in the Northwest Corps, with a total of 55,000 people, 30,000 troops from the Hanyang battalion, and 25,000 garrisons.

It turned out that the number of cavalry in the Northwest Corps was around 20,000, which was the highest proportion of cavalry among the major corps.

At present, the Northwest Corps has achieved a full cavalry.

Everyone is a cavalryman.

Because of the equipment of the three artifacts of the cavalry, they not only have a strong ability to fight on foot, they can form a military formation when they dismount, they are proficient in infantry tactics, and they are also good at riding on horseback, and they are not afraid to charge the battle on horseback.

The equipment of the three artifacts of the cavalry has greatly accelerated the speed of cavalry training and formation, from the initial three or five years to the present within a year, and the efficiency has been greatly improved.

The comprehensive cavalry of the Northwest Corps is also Cao Ren's self-satisfied achievement, and he mentioned this incident more than once in his performance to Guo Peng, indicating that he is very confident.

This time, Zhang Fei will also be transferred to the 10,000 particularly elite and fierce iron cavalry under Zhang Fei's command, and continue to let Zhang Fei take the lead, join the Northwest Corps, and accept Cao Ren's control.

With the addition of such a new force, the total strength of the Northwest Corps could reach 65,000 men, and it would be easy to restore all of Liangzhou and proclaim the prestige of the country.

Under the premise of such an abundant supply of war horses and transportation horses, the Northwest Corps can even achieve a comprehensive one-man two-horse system, as well as a full-mule horse system for logistics.

Everything can be done with animal transportation, which greatly enhances the ability of the Northwest Corps to march and logistical transportation.

It can be said that the Northwest Corps under Cao Ren is the most capable corps of the Guo Wei Empire with long-term combat capabilities.

In fact, the large cavalry regiment is not needed in Jiangnan.

The south of the Yangtze River is covered with dense water networks, hills, broken plains, swamps, and many undeveloped primeval jungles, which are really not suitable for the gallop of large-scale cavalry regiments.

Therefore, the three major corps in the south of the Yangtze River are mainly infantry troops, as well as naval armies, and troops that are good at mountain warfare.

The main cavalry were concentrated in Liangzhou, Bingzhou and Youzhou.

Such a corps under Cao Ren was prepared by Guo Peng for the Western Regions.

In the future, this powerful cavalry legion will enter the Western Regions and establish his prestige in the Western Regions.

Before that, Guo Peng needed to send enough secret agents to the Western Regions to understand the specific situation of the countries in the Western Regions in an all-round way.

Otherwise, you don't know anything, what's the use of being blind in both eyes?

Twenty years ago...... No, according to the lag of information, this is already the information of thirty or forty years ago, and the vicissitudes of life, the information of thirty or forty years ago is really not very useful.
