According to Dong Zhuo's confession, Liu Zhang excavated several treasure burial points in Chang'an and Yiwu, and harvested very richly, he asked people to use these money to buy a large amount of grain from the hands of Yi and Jing wealthy households, ploughing cattle and transport them to Chang'an, and ordered people to build many production tools, ready to rent them to the people of Guanzhong for farming in the coming year.

At the same time, Liu Zhang asked people to hold Dong Zhuo's letter to persuade the remnants of Xiliang scattered everywhere to surrender, and the Xiliang army saw that the general trend had gone, and there was Dong Zhuo's order, and they surrendered one after another to ask for forgiveness. Liu Zhang almost bloodless took the remnants of the Xiliang Army, only Duan Xuan had a strong army (after Li Dao left, he recruited a large number of soldiers, Wuwei After a long war, the people were not happy, and the people were in a difficult situation, and many strong men had joined the army in order to have two meals and one night, and Duan Zhuo had raised 40,000 people in a mere time, no wonder his confidence was inflated), and when he saw Dong Zhuo's defeat, he was self-reliant, and not only ordered the defenders of Wuwei to step up preparations for war, but also killed Liu Zhang's messenger who held Dong Zhuo's letter to persuade him to surrender. Liu Zhang was furious after receiving the report, and ordered Wei Yan and the others to be sure to annihilate Duan Xuan, who was trying to use his mantis arm as a car.

Wei Yan got the order, and then began to arrange the attack on this last Xiliang army, in order to solve Duan Xuan in the shortest possible time, but also to minimize the casualties of the Yizhou army, he ordered people to find Beigong Yan, asked Beigong Yan to write a letter, and secretly handed it over to the two thousand Qiang cavalry generals under Duan Xuan's command. After receiving Beigong Yan's letter, this Qiang general named Li Jing agreed with Wei Yan that he would send troops at an appropriate time to cooperate with Wei Yan to attack Duan Xuan.

At the same time, Ma Chao, who had fled into Zhangye, quietly returned to Wuwei and met with Wei Yan, who was the ancestor of the army, and quietly summoned Wuwei's Ma Teng's old troops under Wei Yan's arrangement to cooperate with Wei Yan to eliminate Duan Xuan. It turned out that since he knew that Ma Teng and Han Sui perished, Liu Zhang sent an envoy to Zhangye to look for Ma Chao and others, these people did not fail in their mission, and fortunately found Ma Chao, who was a little disheartened, and the desperate Ma Chao saw Liu Zhang's messenger, seeing that revenge was hopeful, Ma Chao immediately agreed to join Liu Zhang's command, and then returned to Wuwei with Ma Dai, Pang De and others in disguise.

Needless to say, although Duan Xuan had tens of thousands of soldiers and horses under his command, most of them were new soldiers, and they were completely a group of rabble, plus the Qiang cavalry turned against him, and Ma Teng's old department also took advantage of the situation.

Wei Yan knew that Ma had a very high reputation in Wuwei, and was worried that Ma Chao would cause trouble if he stayed in Wuwei, so he asked Ma Chao to go to Chang'an with 2,000 cavalry in the name of the threat of the Xiongnu.

Liu Zhang learned that Jin Ma Chao came to surrender, and there were Pang De, Ma Dai two brave generals together, overjoyed, in front of everyone Ma Chao promised, he will select soldiers from the captives and recruit recruits from the people of Guanzhong and Qiang, after primary training, a new divisional cavalry unit will be formed, and Ma Chao will become the commander of the newly formed cavalry division like Zhang Xiu, Pang De and Ma Dai will also have their own reuse, Ma Chao, who has lost all his territory, readily accepts this, for Liu Zhang hopes that he and Pang De, Ma Dai temporarily assist Hua Xiong, Beigong Yan, Li Dian and the others agreed to the order without hesitation.

Liu Zhang got three generals in one day, and immediately ordered a big feast to celebrate, and after getting drunk, he naturally inevitably had a upside down with Su Fei and Shihan......

After Wei Yan solved Duan Xuan's problem, the troops did not stop and continued to advance to the northwest.

Liangzhou is a land of bitter and cold people, sparsely populated, and this phenomenon is worse in the northwest, especially in the three counties of Zhangye, Jiuquan, and Dunhuang, and the subject country of Zhangye and Zhangye Juyan, the total population of the three counties and the two countries at this time is less than 200,000. Of course, the original number was even larger, which was all thanks to the prosperity of the Silk Road, but when Emperor Ling, the Han Empire broke out one after another Qiang rebellion and the Yellow Turban Rebellion, and the declining Han Dynasty was unable to manage the Western Regions. After the rebellion of the Qiang people was quelled, many stragglers rushed into Zhangye and other places, robbing houses, killing people and stealing goods, and the people who lived by the trade routes lost their source of livelihood, and after the garrison withdrew, there was no one to protect them, so the family migrants abounded, and the population of Zhangye and other places naturally dropped. No wonder whether Ma Teng, Han Sui, or Dong Zhuo are indifferent to Zhangye and other places that are close at hand, they all understand that it is easy to lay down a big piece of land in the northwest, but it is difficult to operate, and the poor people of Ding Dangxiang not only can't provide much tax, but you also have to pay money to operate (since it is your jurisdiction, you always have to garrison the army, right?). The army is a place where money is like flowing water), which has also caused more than ten years of anarchy in the vast area west of Wuwei.

Wei Yan led the 12th and 15th Infantry Divisions, the 8th Independent Infantry Brigade, the 3rd Cavalry Division, and the 1st Field Corps, a total of more than 45,000 people and infantry troops all the way to the west. Wei Yan easily eliminated more than ten evil horse bandits, and the army went straight to the first line of Yumen and Yangguan, so that it could be truly announced that the entire Liangzhou was included in Liu Zhang's territory.

Wei Yan obeyed Liu Zhang's order, did not continue to advance, the army stationed in Yumen Pass, Yangguan and other places, busy repairing passes, reassuring the people and surrendering bandits, etc., and at the same time recruited some people who knew the situation in the Western Regions, asked them to lead the way, led the envoys to various countries to promote the prestige of the Han Dynasty, and communicated with various countries on the reopening of trade routes, hoping that all countries could ensure the safety of the Han caravan after entering the Western Regions.

In fact, with Liu Zhang's current strength, he is fully capable of completely controlling the Western Regions, but he has no intention of resetting the Western Regions for the time being, there are many small countries in the Western Regions, and there are many contradictions between countries, and the situation is very complicated, he now has to concentrate on the Central Plains, if he falls into the quagmire of the Western Regions and delays the war in the Central Plains, it will be worth the loss.

Liu Zhang's plan is to station an elite army on the front line of Yumen and Yangguan to deter the countries of the Western Regions, not too much, about 20,000. The largest of the countries in the Western Regions is Khotan, Yanqi and Shule, of which the largest Khotan is only about 80,000, Yanqi is about 50,000, Shule is slightly more than Yanqi, about 65,000, and other small countries have fewer populations, some only a few thousand. Although 20,000 elites are not enough to capture the Western Regions, it is also the largest armed force in the Western Regions, and these 20,000 elite soldiers are like hanging a knife over the heads of the countries in the Western Regions, so that they dare not fight the idea of caravans. As long as the caravan can safely travel between the Western Regions and Chang'an, Chengdu, Xiangyang and other places, it can bring Liu Zhang great wealth, and he can use this wealth to speed up the war in the Central Plains, and wait until the Central Plains is unified, and then wave the northwest to sweep the Western Regions.

However, when the war reports from Yumen and Yangguan arrived in the hands of Liu Zhang, who was far away in Chang'an, he had a headache, why? It turned out that he was worrying about who should be allowed to sit in Yumen and Yangguan. Whether it is Wei Yan, Chen Gong, or Shan Fu, everything in the northwest is a piece of cake, but Liu Zhang doesn't want to leave them in that position, it's not that Liu Zhang doesn't trust them, but if they are allowed to deter the Western Regions and protect the trade route, wouldn't it be too big and useless?

In the end, after consulting with Man Chong, Xun You and others, Liu Zhang decided to appoint Yan Pu, deputy chief of staff of the Fourth Field Army, as the chief of staff of the Western Regions, temporarily stationed in Yumen, fully responsible for military and political affairs west of Wuwei, and the Changshi Mansion was under the jurisdiction of the Pang Yi Independent Eighth Brigade, Yang Ren's Independent Fifth Brigade, Liang Xi's Third Cavalry Division and a new brigade (composed of new recruits and some surrendered troops, the number of 6,000 people) and other departments, with a total strength of 30,000 troops, of which 5,000 were stationed in Yangguan, 7,000 were stationed in Yumen, 10,000 were stationed in various counties to protect the territory and the people, and the rest were stationed along the trade road to protect the caravan from horse bandits.
