If the entire northern land is regarded as a battlefield, then the northeast of the right flank of the Yulin battalion as the central formation is the Southern Xiongnu Wang Ting Meiji, and the left flank area due north and west is Yinshan.

Yin Mountain, the terrain is very peculiar, just like a ladder of nature, the north slope of Yin Mountain is gentle, in the Inner Mongolia Plateau, more wind and less rain, the temperature is very cold, and the south slope of Yin Mountain is steep, and there is precipitation brought by the flow of big rivers, the temperature is relatively warmer.

And to capture Yinshan, it is necessary to take Wuyuan.

Wuyuan County, because there are five fertile pastures along the big river in a row, Anyang, Chengyi, Yiliang, Heyin, Linwo, and north of Wuyuan, is the most famous Yinshan South foot of a passage, known as Manyi Valley.

The Xianbei Zuo Dadang, who originally went south to attack Feiqian, was stationed here.

The defense system of the entire Yinshan Mountain is the Xianbei general stationed in the Guangmu Prairie under the Yinshan Mountain, commanding the right big danghu stationed in the fertile field and the left big danghu in the five plains, each commanding 10,000 cavalry, that is to say, this time Fei Qian went north, facing 20,000 cavalry troops.

Of course, Fei Qian didn't think about saying that he would have to carry it head-on with 20,000 cavalry, as long as Wuyuan was taken down and the Yinshan passage of Manyi Valley was cut off, he could block the Xianbei general and the right big danghu in Yinshan under Yinshan, and then slowly push it in little by little......

Anyway, the big river has created the abundant water and grass in the south of Yinshan, and it has also brought two huge desert areas, which just block the passage in the south of Yinshan, and the west and north of Yinshan grassland are steep Yinshan mountains, so as long as the mouth of Wuyuan is blocked, it is equivalent to sealing these people in the pocket of Xianbei.

Of course, this pocket is not so easy to seal.

Because of the foot soldiers and baggage carts, Fei Qian's group did not walk fast, and when they arrived at the abandoned city of Zhenlin, which is more than 100 miles northwest of Epingding, they were stationed.

Zhenlin was originally a city in the northernmost part of Shangjun, and it was also the forefront of Shangjun's defense against the Hu people, but now the glory that may have existed in the past is gone, and only the broken walls remain, proving that this was once a human settlement.

"Gongming, if you are the commander of Xianbei, where will you attack next?" Fei dived off the horse, stood on the side of the ruined Zhenlin City wall, and asked Xu Huangdao.

"Yuvro?" Xu Huang said.

Fei Qian nodded, agreeing with Xu Huang's opinion.

As long as the commander of the Xianbei people is not a fool, he will inevitably attack Yu Fu Luo first, the reason is very simple, Yu Fu Luo has just entered the South Royal Court, and the people's hearts have not yet settled, and it is the time when it takes time to integrate.

And there is an additional advantage of attacking Yuvro, that is, it can collect the defeated troops of the Southern Huns and make them the forerunner, just like a snowball, every time the snow powder is contaminated, it will always make the snowball bigger, and finally become a behemoth.

The problem is that Fei Qian also wants to roll the snowball of the Southern Huns......

"Then do you think Yuvro can resist it?" Fei Qian asked the second question.

The reason why Fei Qian asked Xu Huang these questions was that he hoped that Xu Huang would focus more on thinking about the overall battle situation, rather than focusing more on the implementation of specific affairs.

It is enough for Ma Yue and Zhang Ji to carry out military orders, and the commander of the army always needs to have a person who can have a higher vision and look down on the entire battlefield, Xu Huang is originally relatively smart, and Fei Qian naturally does not want to bury Xu Huang's talent in this regard.

Xu Huang thought for a moment and said: "There are no less than 10,000 cavalry in the Southern Royal Court, plus more than 5,000 cavalry brought by Yu Fuluo, so it is not a big problem to gather 20,000 cavalry...... If the Xianbei people want to win, then at least more than 20,000 horsemen must be dispatched, maybe the number of 30,000 horsemen will be more certain, but ......"

“…… Would the Xianbei people really be willing to send twenty or thirty thousand cavalry to attack the Southern Royal Court? Xu Huang asked Fei Qian, "That's almost more than one-third of Budugen's troops...... And in the event of the defeat of Yuvro, the pressure on our side will probably not be small......"

Xu Huang didn't have any opinion on Fei Qian's use of Yu Fuluo as a shield, he just had some worries.

In case the shield of the Southern Xiongnu is not too strong and fails to play its due role, once the Meiji Royal Court in the northeast cannot withstand the attack of the Xianbei people, then Feiqian's side will not only have to deal with the Xianbei troops in Yinshan, but also need to face the powerful offensive of the Budugen group.

Although it is said that Zhao Yun has been sent to Budugen's flank to harass him, it is difficult to grasp whether he can be in place in time and whether he can have the desired effect.

Fei Qian also nodded, Xu Huang's worries were also reasonable.

After all, on the battlefield in ancient times, the most difficult thing is the transmission of communication information, don't look at the history books at every turn, there are several armies out together, as if a big battle is determined by how many armies are coordinated, but in fact, these armies are basically rarely coordinated to fight, in most cases are each fighting their own, the reason is very simple, that is, there is no way to transmit information.

Therefore, if you want to fight together, or even use a semi-friendly army like Yu Fu Luo to fight, you must make a certain arrangement for the battlefield, so that the whole battle situation is tilted in the direction you want.

Just like fishing, you can catch fish without bait, but the area where you put bait always gathers more fish, which naturally increases the success rate of the catch.

Fei Xi picked up a sharper stone on the ground, and then motioned to Xu Huang to squat down together, drew a schematic diagram, and said: "This is Zhenlin, and then Meiji is in our northeast, and there is a horizontal desert area in the north of Meiji, and there is a big river to obstruct, so the Xianbei people want to attack Meiji from the Yanmen area in the clouds, if you don't want to make a detour, you can only take the road between Shanan and Tongguo...... Therefore, if Budugen wants to attack us, unless we go south around Taihang Mountain and take Taiyuan, we will inevitably pass through Meiji ......"

"Then we here, the Xianbei people near Yinshan Mountain in our northwest direction, if we want to attack the Han land in the south, we must either go south from Meiji, cross the Great Wall of Zhao along the Fenshui, and take the Yuanyin side of the mountain, or defeat us head-on and take the route of Zhenlin, Baitu, and Yulin......"

"Zhonglang is here to see how the Xianbei people are selected," Xu Huang said while looking at ......the schematic diagram, "Or ...... There are other pictures......"

Fei Qian laughed, then stood up, stretched out his foot a few times to cross out the schematic diagram, and said, "Okay, since you guessed it, let's go and prepare......"
