On the south side of the Yuncheng Basin is relatively low, it is called the slope, while on the Emei Ridge, it is called the slope. The entire Emei Ridge has a flat surface, boundless, facing water on three sides and facing south.

It is precisely because of the erosion of this flowing water that steep loess cliffs and winding loess gullies are formed around the platform. The edges of the platform are mostly broken loess landforms with ravines.

If you look at Emei Ridge from the south direction of the Yuncheng Basin, this Emei Ridge is like a huge loess castle that suddenly rises from the plain. Its loess cliff runs across the east and west, stretching for nearly two hundred miles, comparable to the cliffs that isolate the frozen soil in the song of ice and fire.

On the west side of Emei Ridge, near the river, is the famous Longmen Ferry.

Of course, there are also some small ferry crossings, such as Fenyin Ferry.

In Emei Ridge, near the north, there are two high mountains, Gushan and Jiwang Mountain. The two mountains are not far apart, just like two eyes on a platform. The Fen River north of Emei Ridge is different from later generations. Because of its good soil and water conservation, its current flow is still very large in the Han Dynasty. Only in autumn and winter, the Fen River weakens a little, so it has become a natural moat to the north of Emei Ridge, which naturally has a certain defensive effect on the nomadic peoples in the north. Therefore, since ancient times, Emei Ridge has been an important line of defense for the Hedong area to defend against the nomadic peoples in the north, but now it has to face swords and guns from the Han Dynasty...

Zhang Xiu's logistics troops are now stationed in Zhangbi on Emei Ridge.

Zhang Bi is located at the northern end of Emei Ridge, near the Fen River. It was originally a military fortress used to defend against the Huns, but was later destroyed by the Xianbei hands, and was later restored by Fei Qian.

It is precisely because of this that when Fei dived to the northeast of the river, the entire area north of Emei Ridge was relatively desolate and sparsely populated. Even if everyone knew that the land of Linfen was surrounded by Fen River, if the canal water conservancy was repaired, it would be 10,000 mu of fertile land, but no one would come here to reclaim it. Compared with the Linfen Valley, Yuncheng Basin would be safer under the threat of the Hu people in the north.

It was not until Fei Qian defeated the Xianbei, educated the Huns, and expanded the entire border to the Yinshan area of ​​the Yellow River and Hetao area that the Linfen Basin became a hot commodity again.

This has led to serious inconsistencies in the relationship between the north and south of Emei Ling...

Zhang Xiu looked down the slope of Emei Ridge and couldn't help but sigh: "Why do you have to come? Why do you have to come! I have always thought about taking advantage of it, but have you ever thought that this advantage is so easy to take advantage? Now it has become a means of Cao's thief!"

Behind Zhang Xiu, Xun Chen also wore a sleeved armor, but he did not wear a pussy, but was still wearing a Jinxian crown. After hearing Zhang Xiu's words, he smiled and said, "These are all caused by the people of Hedong, and they are not worth pitying."

Zhang Xiu shook his spear, "That's right. He just pity these innocent people. As for the people in Hedong...haha..."

Xun Chen said: "The Cao army was disturbed to cover up your and my eyes. Now there must be thieves in this round of refugees."

Zhang Xiu tskated, "If you kill him, it would be simple."

A few days ago, Zhang Xiu raided and defeated the Cao army who went to Yi County to build a camp, and led some Cao army and civilians back to Linfen. This made the Cao army unable to continue to promote the strategy of building a hard camp, and could only think about it another way.

"At some point, I was not very worried and caused trouble for my lord." Zhang Xiu gritted his teeth and said, "Cao Thief is extremely shameless, he actually used such a despicable method! He deserves to die!"

Xun Chen comforted: "General Zhang does not need to blame himself. Cao thieves have many tricks and their lords are good at being benevolent and virtuous, so they must have this test. One came this time, on the order of the lord, they brought some civil servants to help so that General Zhang can rest assured, and the other was to deal with these northbound refugees..."

That’s right, refugees cannot be allowed to pour into Linfen Valley directly.

After Fei Qian received the news that Cao Cao began to act, he immediately judged the intention of Cao's army. This time, he used the people and forced the young and old to break through the Emei Ridge defense line and create an opportunity to invade Linfen.

Fei Qian believed that Cao Cao must have known the strategic importance of Emei Ridge.

Whether it is for the Linfen Valley in the north or the Yuncheng Basin in the south, it is very important. This is not only a barrier for southern forces to defend northwards, but also a strategic fortress for raising energy and attacking northwards.

In the Yuncheng Basin south of Emei Ridge, although there are Yixian, Pi, Wenxi, Anyi, Puban and other counties, these counties and townships actually do not provide a better defense system, and even if they occupy it, there is no place to stick to it.

Even if this matter is not a military expert, he only needs to know some of the history of the Spring and Autumn Period. During the Spring and Autumn Period, Emei Ridge, Zijin Mountain, and Fen River were the dangers of mountains and rivers protecting the capital of Jin State and the last line of defense for the capital of Jin State. During the entire Spring and Autumn Period, except for the negligent defense in 550 BC, the army of Qi successfully attacked and entered the hinterland of Jin State, for hundreds of years, other vassal states were rarely able to break through Emei Ridge.

It was obviously a time-consuming and extremely difficult thing for Cao Cao to attack Emei Ridge in a conventional way.

The Emei Ridge is vast and flat, and the cavalry can go lateral and lateral, while the short legs of the Cao army's infantry obviously cannot keep up with the footsteps of the cavalry. Therefore, among these refugees, Cao Cao used the "resistance" or "traps" to block the Hussar cavalry to invisibly divide the battlefield into pieces to form a local advantage.
