Originally, Liu Yu also reached a tacit agreement with Murong Rou, he did not enter Hebei, so that Murong Chong and Murong Chui had no chance to unite with the outside world, forcing Murong Chong to be cornered, and it was best to let him bèi'bī die, while Murong Rou expressed his willingness to let Liu Yu determine the occupation of the first line of Shandong.

This condition actually met Liu Yu's expectations, so he agreed at that time. Of course, the main reason for agreeing is actually because the army has long been very tired, and during the last Northern Expedition, it was almost exhausted, because the last time it was really unjust, and it was lost to its own people, so that everyone was not convinced, and they held back their strength to fight all the way from Jingkou to Guanggu.

But manpower is sometimes exhausted, they are iron army, but not iron men, they will be tired, they will be hard, and they will not be able to endure xìngzi, now, they have almost reached the limit, if they continue to fight, not to mention that they can't swallow Hebei at all, even Huaibei and Shandong, which have already been obtained, may also be lost, it will be too cost-effective.

Of course, one of the reasons is also because Fu Rui's army, after all, is still lying on the side and rear, although Liu Yu is not without deployment, but after all, Fu Rui is not comparable to others, Liu Yu also got the detailed information of the previous battle in Beibi Mountain, he knows that Fu Rui is not easy to deal with, and only by going into battle himself can he be sure to block it.

But what Liu Yu never imagined was that Fu Rui actually set out ten days earlier than he expected, and in the first battle, he broke through the important town of Zhongli, and the defender Wang Wang died in battle, and all the more than 3,000 people of the Jin army were killed, and the two Huai earthquakes were great!

As we all know, the capital of the Jin Kingdom is Jiankang, because Jiankang has unique conditions as the capital of the south of the Yangtze River. Jiankang is close to the river, the transportation is convenient, the west passes Bashu, Jingxiang, the east is connected to Sanwu, and the north is two Huai. Bashu and Jingxiang are enough to protect the upstream; Sanwu is rich enough to provide human and material support; The Lianghuai region is a place for attacking and defending and retreating, and attacking and defending should be based on Jiankang.

Jiankang itself is based on the big river in front of the river, and it is close to Chongling in the south, and the situation is unique and victorious. Because there are many hills around Jiankang City, such as Zhong Mountain, Fuzhou Mountain, and Shogunate Mountain. Sun Wu originally built the capital here, Zhuge Liang called "Jinling, Zhongshan Longpan, stone tiger, the emperor's house." ”

Of course, Jiankang, the capital of Jiankang, is actually a last resort, because Luoyang was captured by the Hu people, but the Hu people did not say that they took your land, even if it was over, they also wanted to unify the world, so how to defend Jiangnan is a big problem. And the entire defensive system, the most important thing, is actually the first line of the Huai River.

As the old saying goes, to guard the river must guard the Huai, and the Huai River and the Yangtze River play a double barrier role. The reason is very simple, since the north and south were divided and ruled, the Huai River is often used as the barrier of the Yangtze River. Jiangnan takes Jianghuai as a risk, and those who guard the river are better than guarding Huai. As long as the south can hold the line of the Huai River and ensure that the opponent's cavalry is blocked, then half of the country will be safe, and if the northern regime can break through the Huai River defense line, the south of the Yangtze River will definitely perish.

If the defense of the Yangtze River is purely passive, then the Huai River has both defensive and active offensive significance. The south confronts the north, and in terms of defending, the Huai River can be used as depth through the vast area of Huainan; In terms of attack, it is possible to enter the Central Plains out of Huaibei. Most of the tributaries of the Huai River originate from Huaibei, especially Surabaya, and can be connected to the Yellow River after a little excavation, so that the power of the south can be cast far into the Yellow River Basin; And guarding the Yangtze River alone, if one place is broken, it has entered its henchmen.

The vortex river is another important communication line between the Central Plains and the Jianghuai River. The confluence of the vortex river and the Huai River is called the vortex mouth. Zhongli is facing the mouth of the vortex, blocking the rush of the vortex river. At the time of the confrontation between the north and the south, Zhongli and Shouchun were both important towns in Huaixi. If you want to defend the Huai River, Zhongli is rushing south from the direction of Xu Luo, originally Liu Yu sent Wang Wang, but he felt that Wang Wangqi was not enterprising enough, but there was more than enough to defend the city, as long as Zhongli County was still in hand, then his back road was guaranteed.

Moreover, Zhongli County is high and deep, with abundant grain and grass, and the dangers of rivers and mountains, Liu Yu also left the most elite army to garrison, and it must be no problem to defend for half a month. And half a month, even if it is far away, it will be too late to save it.

Liu Yu never calculated, in just three days, Zhongli County was broken, and Fu Rui did not give up, and had already sent troops to take Shouchun directly.

If Shouchun makes another mistake, it will be a big trouble.

The tributaries of the upper reaches of the Huai River mainly include the Ying River and the Whirlpool River. The confluence of the Ying River and the Huai River is called Yingkou, and the confluence of the Whirlpool River and the Huai River is called the Whirlpool. Shouchun is facing Yingkou, blocking the enemy in the direction of Yinghe River and Huai River; Zhongli is facing the mouth of the vortex, blocking the rush of the vortex river.

Therefore, Shouchun controls Huaiying, and takes Jiangtuo with Jiangtuo, which is the key point of the northwest and the shield of the southeast. In addition, the Shouchun area, a part of the Huanghuai Plain, has fertile soil, convenient irrigation, and is suitable for tun farming. Therefore, its geographical advantage is enough to defend the war.

If Shouchun is lost, it is obvious that Liu Yu's back road will be completely cut off, and whether the tens of thousands of troops can go back is a big problem. Originally, this time, in order to achieve a sudden effect and ensure the speed of the march, Liu Yu ordered to travel lightly and go north at a speed. But if Fu Rui cuts off his own line of communication, when the time comes, the army is short of food, and the invincible Beifu Army will still be able to maintain its fighting spirit, that is a question.

In any case, Liu Yu must react quickly, since the Guanggu generation has been taken, Liu Yu will leave He Wuji to guard Guanggu, and he will lead the main force to go south under the starry night.

A fierce war is about to start.

*******************************

Jincheng County is actually a vast and sparsely populated place, in addition to Nan'an, Jincheng, Warrior Fort and other cities, in fact, many places, are unmanned, and unlike Dunhuang outside the city of desert Gobi, here is actually mainly grassland.

In the grassland in spring, everything recovers, flowers are in full bloom, the sky is white clouds, and the ground is cattle and sheep, this scenery is really beautiful. On weekdays, the leisurely shepherds will herd sheep and sing here, and the sturdy young man will go to please his beloved girl.

However, since the rebellion of the beggar Guoren, he ordered the herdsmen here to temporarily gather and not to move, because at that time, almost as soon as he raised the army, Duan Ye had already been ordered to come to crusade, if those herdsmen were allowed to continue grazing on the grassland, if they were loyal, they would be tú'shā by the army, and their betrayal would bring them a lot of trouble, so it was better to come to the clear field of the strong wall with peace of mind.

Now, although Fort Warrior has changed hands, Duan Ye had a lot of things to do at that time, and he didn't take care of this stubble. Moreover, it is not advisable to let them graze freely until the internal purge is completed.

But now, Duan Ye himself has brought some people to this beautiful Gannan grass beach.
