In fact, as early as when the troops were sent to attack Zhujianze, the plateau already had the idea of attacking Yinshan and attacking the Xiongnu camp, the reason was that on the one hand, the threat of the Xiongnu in Yinshan to Daijun was indeed too great, and this Xiongnu force must be removed, on the other hand, it was also hoped to give the Xiongnu a stern lesson, so that the Xiongnu understood that Daijun was never easy to provoke, so that the Xiongnu would not dare to invade the area of Daijun lightly in the future, so as not to suffer the enemy in the future.

Although the current Xiongnu nation is in the rising period, but has not yet reached its heyday, its own population is not much, less than two million, and there are many nomads who can compete with the Xiongnu in the northern grasslands, there is not enough strength to fully invade the south, this time send the right Xian Wang Tou Su to lead a Xiongnu south to Yinshan to station, but also heard that the Zhao State was destroyed, Li Mu died, so test the reaction of Daijun, if the Yinshan camp is breached, it will definitely be able to make the Huns' future actions somewhat restrained, Win at least a few years of steady time for the northern border of Daigun. On the one hand, the plateau can strengthen the defense of the northern border, and on the other hand, it can also gain a certain amount of time for stable development.

However, the assault on Yinshan is still just an idea, if it is to be truly realized, there is still a lot of work to be done, and before the preparations are completed, the plateau does not plan to make a big fanfare, only let a few people know. Therefore, there were only four people who participated in the discussion: Yuan Xuan, Li Yinghong, Jiang Huanwu, and Ling Feng.

But after Yuan Xuan listened to Gao Yuan's plan, he still didn't say anything for a long time. Although the plateau asked him to find people who had been to Yinshan, Yuan Xuan could guess a few points, but listening to the plateau himself, Yuan Xuan was once again shocked by the boldness of the plateau, because in this era, this kind of deep into the barren land, long-distance marching and raiding tactics has not yet had a successful example, like the plateau, running three hundred miles, attacking Zhujianze, it is an unprecedented battle, and now the plateau actually plans to travel two or three thousand miles away to attack the camp of the Huns, although Yuan Xuan is also a veteran general who has been in battle for a long time, But I still think that this idea of the plateau is too whimsical.

Of course, Gao Yuan also knows that this kind of long-distance raid tactics is indeed a new tactic in this era, on the one hand, it is the concept of people, on the other hand, the cavalry tactics of this era are not yet mature, and in the other time and space, in the Han and Tang dynasties, the long drive went straight into the north of the Saibei, which is also the time when the development of cavalry tactics in ancient China reached its peak. However, now Daijun has basically given up the chariot and established an army with the cavalry as the main force, and the application of double-bridge saddles and horse pedals, the combat effectiveness of the Daijun cavalry is not much different from that of the Han and Tang dynasties, and it can also be said that the objective conditions for the implementation of such long-distance raid tactics have been completely prepared.

And the tactical concept of long-distance raids is not a problem, at least in the mind of the plateau, there are countless similar successful examples. So all that is left now is a sound tactical plan and preparation.

The most important point is to send a reconnaissance team to infiltrate the Yinshan area to understand the details of the Xiongnu, as well as the route of the march and the camping points along the way, there must be detailed arrangements. Because in the northern part of the army, food supply is still secondary, and the army can carry at least fifteen to twenty days of food, plus hunting along the way, and if necessary, they can also kill horses to satisfy hunger, and ensure a supply of thirty days, which is completely feasible. The most important point is the water source, the reason why Zhujianze was able to become a temporary camp for the Xiongnu army, and it used to be a trading market for various ethnic groups outside the Saiwai is because there is a large lake here with sufficient water sources. Therefore, it is necessary to ensure that there is enough water on the route of the march.

Although Gao Yuan wanted to personally lead the team and sneak into the Yinshan area to reconnoiter the situation of the Xiongnu, this was obviously impossible, so he could only hand over this important task to Jiang Huanwu and Ling Feng to complete. That's why the two of them were able to participate in this discussion. However, the matter of reconnaissance and road exploration, now Jiang Huanwu and Ling Feng are familiar with the road, in these successive wars, the Wu'an army has been able to achieve heavy victories, Jiang Huanwu and Ling Feng's special combat team efforts are inseparable, it is precisely because they have cleared the road for the army and explored the reality of the enemy army, so that the plateau can grasp the enemy's movements, make targeted arrangements, and be able to win victory after victory. It can be said that the special combat team led by Jiang Huanwu and Ling Feng is the biggest hero of the Wu'an Army.

Therefore, this time to go to the Yinshan area to reconnoiter the situation of the Xiongnu, and to set the important task of setting the march route of the army, can only be handed over to them again. And the plan for the use of troops in the body also needs to wait for them to come back and report the situation of the Huns before it can be formulated. And Yuan Xuan breathed a sigh of relief, although Gao Yuan's idea was very bold, but when it was implemented, he was still quite cautious and cautious. It's not just a rush to make a rash move.

Of course, Jiang Huanwu and Ling Feng didn't have anything to say, and immediately took over this important task. Although Ling Feng was about to face a temporary separation from Yun Na, Ling Feng also knew that there were still eight members of the Bai Ling clan in the Xiongnu camp, and this was also a great opportunity to curry favor with Yun Juan's aunt and nephew and leave them with a good impression. Because Ling Feng could feel that Yun Na had no scheming and had completely accepted herself, but Yun Juan was obviously wary of herself. Therefore, Ling Feng was also very energetic, and after the meeting ended, Ling Feng immediately began to prepare.

Yuan Xuan and Jiang Huanwu were also in action, Yuan Xuan was looking for people who had been to Yinshan among the people, while Jiang Huanwu interrogated the captured Xiongnu captives and learned about the situation of the Xiongnu camp in Yinshan from them.

Of course, this reconnaissance mission can not be completed in a few days, and the original plan of the plateau is to inspect the two counties of Yanmen and Yunzhong, because to resist the attack of the Hun army, it has been delayed for more than ten days in Yanmen County, but the harvest is also very huge, not only defeated the attack of the Hun army, harvested a large number of materials and livestock, but also subdued the population of more than 300,000 people outside Yanmen Pass, so the next step is to go to Yunzhong County to complete this inspection plan.

So on the next day, Gao Yuan led a large army from Yanmen County and rushed to Yunzhong County, leaving only Jiang Huanwu, Ling Feng and more than 100 soldiers of the special combat team in Yanmen County. And Yun Juan, Yun Na's aunt and nephew also naturally set off with the army. Before leaving, Yun Na also made a special trip to say goodbye to Ling Feng, and she looked a little reluctant, which also made Gao Yuan, Li Yinghong, Yun Yao and others very funny, it seems that these two people are making good progress. Although Yun Juan had a gloomy look, there was nothing she could do.

After the army set out from Yanmen Pass, it only rested for a day on the way before reaching Yunzhong County. After receiving the report, Chen Shi, the chief general stationed in Yunzhong County, also led his army out of the city to meet the plateau and his party.

Moreover, at this time, Chen Shi also knew the news of Gao Yuan's defeat of the Xiongnu army in Yanmen County, so he also congratulated Gao Yuan in person. Then the plateau and his party were welcomed into the city to rest.

After resting for the night, Gao Yuan, accompanied by Chen Shi, toured around Yunzhong County, first to see the settlement of the immigrants from the Yan Kingdom.

At this time, more than 300,000 immigrants from Yan have moved to Yunzhong County to settle down, and now half of the immigrants from Yan have moved into new homes, and the other half of their new homes are still under construction, and before the end of the year, all people can move into their new homes for the New Year.

After a delay of more than ten days in Yanmen County, the autumn harvest is nearing the end, but when Gao Yuan inspected Yunzhong County, he still found that there are still a large number of people working hard in the fields, because the immigrants of Yanguo have joined, so that the population of Yunzhong County has nearly tripled, close to 500,000, so a large amount of wasteland needs to be reclaimed next year to ensure next year's income, and at this time, the immigrants of Yanguo are sorting out the fields to be reclaimed and preparing for next year's spring ploughing.

In addition, there is also a heavy project in Yunzhong County, that is, to open a canal, because to reclaim wasteland, it is necessary to ensure sufficient water sources, so the canal must be opened first, which is an inevitable project. And Yunzhong County is located at the end of the Yellow River, there are several tributaries of the Yellow River, the water source is very sufficient, and there are enough conditions for opening the canal, when the plateau is inspecting, it also sees that the five main canals are being excavated, and along both sides of the canal, are the fields that are being organized, and the branches of the canals are also marked out one by one, forming a huge canal network.

Although it takes a lot of money to complete the whole project, and it will take at least three to five years, or even longer, to complete, once completed, the social productivity and economic development of Yunzhong County will be greatly improved. In the future, the plateau will attack from Yunzhong County and attack the logistics base in the north of Qin, which can also become a reality.

Building houses, preparing fields, and opening canals are also the main jobs for Yan immigrants to exchange their labor for remuneration and maintain their lives, but because these three jobs are related to the vital interests of Yan immigrants themselves, they live in houses and the whole field is also their own, and the canals are opened for better planting, and the remuneration standards formulated by the Yunzhong County Government are also very reasonable, and they do not need to work hard for immigrants, they can completely guarantee their lives, and the immigrants also have hope for the future, so the immigrants not only work very hard, And people's hearts are stable, and they all have a kind of love to live and work in peace and contentment, and now if they are allowed to go back to Yan Kingdom, it is estimated that few people will be willing.

Therefore, in addition to the inspection of Yunzhong County, the plateau has also received many praises from the immigrants, and the immigrants in many places have bowed to the plateau. And the entire Yunzhong County also shows a prosperous scene, which also makes the plateau very satisfied. In fact, not only Yunzhong County, but also Yanmen, Daijun, and Shanggu County are all in a similar situation, and the areas under their rule are generally showing a steaming momentum, and if they can develop for a few years, they can become a force that cannot be underestimated when they are among the nations.
