Early in the morning of the second day, Dong Shouye set off with 20,000 soldiers and horses donated by Dong Min, and the four newcomers, Wang Fang, Wu Xi, Cui Yong, and Zhang Bao, also set off with Dong Shouye.

Dong Min also personally walked out of Yiwu ten miles away to see him off.

After Dong Shouye bid farewell to Dong Min, he led the soldiers and horses all the way west, along the Weishui Shuo River, and arrived at Chencang.

After arriving at Chencang, Dong Shouye did not continue to move westward, but led his troops to the northwest, going upriver along the Huangshui, going through Yulu, passing through Wangxian, passing through Longxian, and then exiting from Longguan in Longxian and entering Liangzhou.

The reason why Dong Shouye walked from here this time was to see how Longguan was shaped.

Longguan, the early Han Dynasty set up a pass, because of the Longshan, so the name Longguan (or Longshan Pass). In the first month of the second year of the Han Dynasty (95 years ago), Emperor Liu Che of the Han Dynasty toured back to the middle of the country, and encountered a thunderstorm through Longguan, and changed Longguan to a large earthquake.

Maybe you may not understand this expression, so to put it simply, Longguan is the street pavilion, and the Ma Tan lost street pavilion is happening here, or near this place. In this way, the key process dù can be seen at a glance.

Dong Shouye wanted to set up heavy troops in Longguan to guard against Xiliang, and at the same time regarded Longguan as a bridgehead and a base for his future operation of Xiliang.

Now Dong Shouye's eyes will not be limited to Chang'an and Luoyang, because no matter how prosperous and rich these two places are, they are such big places. Dong Shouye hoped to look farther away, so that the Xiliang army could occupy more places.

Dong Zhuo, Dong Shouye, father and son are now based in Guanzhong, but nine times out of ten rebels in the world, no one wants to see such a situation, and everyone wants to change.

Dong Zhuo, Dong Shouye, father and son, want to run Guanzhong well, but they must face a big problem, that is, Xiliang. The rebels in Xiliang have been threatening the security of Guanzhong. If Dong Shouye wants to ensure the safety of Guanzhong, he must remove the threat from the rear.

The geographical pattern of ancient China is like a big chessboard, and Guanzhong is located in the northwest corner. There is a saying: "Golden horn and silver edge grass belly." Cao Cao's Yanzhou is a "grass belly", so later generations respect him incomparably, because he was the first in history to use the "grass belly" to dominate the world, and finally achieved a decisive advantage.

Guanzhong occupies an advantage in the process of dominating the world, and it is relatively easy to develop power, so Dong Shouye and his son operate Guanzhong, and then want to develop a broader space.

For Xiliang, Dong Shouye is bound to win in the future. Only by taking precautions can we be invincible.

When he arrived at Longguan, Dong Shouye stood on Longguan and looked at the mountains on both sides of Longguan.

At this time, Jia Xu said: "Son, the west of Guanzhong is Longyou, from Longxi from the Weishui River Valley to the middle of the storm, there is a tendency to build a tower, I have to guard against it!" ”

Dong Shouye heard the words and said: "What does the military advisor mean is to build a young man who passes through the west of Liang? ”

Jia Xu replied: "Yes, if you want to ensure the safety of Guanzhong, you must control Longxi." ”

Dong Shouye thought for a while: "Right now, Han Sui and Ma Teng occupy Longxi, and its terrain is high enough to overlook Guanzhong. It is very easy to attack the key points from Longxi, but it is more difficult to arch Longxi from the Guanzhong! Han Sui, Ma Teng, Tiger and Wolf nature, although a little profit can make them satisfied for a while, but they will definitely harm us, if they are not removed, they will definitely suffer. If our army uses troops against the Kwantung region in the future, once Han Ma makes trouble, he must return to the division, so won't the division and brigade be tired and it will be difficult to achieve great things? ”

Jia Xu nodded and said, "Childe is reasonable, he must prepare 1"

Dong Shouye asked, "I don't know what the military advisor has planned?" ”

Jia Xu smiled and said, "I don't have a clever plan for the time being, but some arrangements are still okay." Gongzi can send his henchmen to guard Dasanguan and Longguan, and then try to arrange Hanyang Taishou as our henchmen. At present, the imperial court is still powerful, and it still has influence in the Xiliang region, and now Liangzhou Mu Weiduan is now asking for help from his son, which is an opportunity. At that time, after repelling Han Sui and Ma Teng, Gongzi Ke proposed to Wei Duan that he should protect Gongzi as the Taishou of Hanyang. Wei Duan asked for help from the imperial court, and Gongzi led the troops to support, Wei Duan can be said to be a favor of the former Gongzi. Childe asked him to return this favor, but he was also dumb and ate coptis, and he couldn't say it. ”

Dong Shouye was puzzled: "Military advisor, this son is going to help his father in Chang'an City, how can he take time out to serve as a taishou in Hanyang?" ”

Jia Xu smiled and said, "Childe only needs to be named, and he doesn't have to kiss himself in Hanyang." At present, several generals under the Gongzi Association have already gained some experience, and it is just right to arrange for them to be in charge alone. At that time, Gongzi planned to be selected as the adjutant of Hanyang Taishou, but asked him to act as the Hanyang Taishou and let him lead the soldiers and horses through Hanyang. At the same time, it is backed by Dasanguan and Longguan, and the soldiers of these two passes have also provided support and support each other. In this way, within a few years, he will be able to gain a firm foothold in Hanyang, and when the time comes, Gongzi will send more people to slowly plot, gradually encroach on Xiliang, and finally control Xiliang in his hands. ”

When Dong Shouye heard this, he nodded and said, "This plan of the military advisor is very clever and very feasible. ”

On the map, it seems that Dasanguan, Longguan and Hanyang County form a triangle.

This triangular defensive ring is very solid. If the enemy encircles Hanyang, the soldiers and horses of Dasanguan and Longguan can go out of the pass to support and contain the enemy, and even if the troops are insufficient, they can also be funded in terms of grain, grass and materials.

If the enemy wants to block the support of Dasanguan and Longguan to Hanyang County, he must send a large number of soldiers and horses to surround Sanguan and Longguan. At the same time, a part of the troops was also allocated to contain the garrison on the Hanyang side.

Moreover, Dasanguan and Longguan are both Xiongguan and precipitous, and some soldiers and horses have no threat to it at all, so that Dasanguan and Longguan will contain a large number of soldiers and horses to relieve the pressure on Hanyang County, and also indirectly support Hanyang.

The subtlety of this arrangement lies in the fact that the three corners of the triangle can be supported at any time, and can be used as strategic support for each other. The garrisons of the three places can exchange military and material exchanges.

There have been similar triangular defense circles in history, that is, after Cao Wei obtained Jingzhou, after a period of operation, established a strategic defense circle with Xiangyang, Hefei and Jiangxia as the triangle, and then Sun Quan wanted to break through this defensive circle several times, but each time it was in vain, but it was a loss of soldiers and generals, and a lot of soldiers and horses were lost in vain. That is, to resist Zhuge Liang's attack. As a result, Cao Wei was able to resist calmly even in the face of the two-front attacks of Eastern Wu and Western Shu, and had the spare strength to launch a counteroffensive.
