After Liu Bei finished reading it, the teacher took out the handwriting of Liu Tao, the imperial history. Yan Imperial Court may use his mentor as a councilor, Dongguan to investigate Confucian scriptures, and participate in the continuation of the work of "Hanji" (historically known as "Dongguan Hanji").

"Look, look, watch also". It refers to tall buildings.

Dongguan is located in Luoyang South Palace. The building is tall and gorgeous, the top floor is twelve high pavilions, the surrounding palaces and pavilions face each other, the green trees are shady, and the environment is elegant. It is the main place for the collection of picture books and archives and the compilation of historical books for the imperial court.

Yilang, Hanzhi, is one of the Lang officials under Guangluxun. The head of the consultant copes, impermanence. The rank ratio is six hundred stones. Recruit more virtuous and upright people.

Liu Bei said with a smile: This Lang official is idle.

The teacher also smiled: This is to continue to write "Han Ji", which is exactly what I want. As a teacher, you can go first, and when everything in the city is arranged, you will come to Luoyang.

Liu Bei nodded: Okay.

The freshness of sandalwood has become a big disaster. Liu Bei didn't remember who had won against Tanshi Huai. This time he went north to fight for thieves, and he was bound to be defeated. Fortunately, Tanshi Huai died young. Xianbei was thus split into three parts, and the previous trend was no longer restored.

After class, Liu Bei returned to Fuzhong. Summoning Wulian to inquire about Xianbei.

Wu Lian said that since Tanshi Huai unified the Xianbei tribes. Then he divided the territory into three. The east of the right Beiping is the east, the right Beiping to the upper valley is the middle, and the west of the upper valley is the west. The three departments are managed by adults, and they are directly under the sandalwood acacia.

Wu Lian also said that there are three things on which the Hu people depend for their survival: "water and grass", "shearling", and "salt land". After Tanshi Huai became the Lord of Xianbei, he set up the royal court in Danhan Mountain, and went to Gaoliu North for more than 300 miles. The soldiers and horses are very prosperous, and the adults in the east and west are all returning. After that, the south copied the edge, the north rejected Ding Ling, the east but the husband, the west hit Wusun, according to the Xiongnu homeland, more than 14,000 miles from east to west, more than 7,000 miles from north to south, covering mountains, rivers, rivers, and salt ponds. Momentum is growing.

As Wu Lian said, there are three resources that the Hu people rely on for survival: "water and grass", "shearling" and "salt land".

Aquatic grass is a natural pasture with abundant aquatic grass. Hay, which means hay. Salt land, naturally, refers to the land where salt is produced.

Nowadays, the salt mainly includes: sea salt, pond salt (lake salt), well salt, and rock salt (mineral salt). Pond salt has a long history, and in the Western Zhou Dynasty, Jiechi has produced pond salt on a large scale. Because the salt pond is in Xie County, Hedong, it is called Xie Pond, also known as "Hedong Salt Pond". And because the salt grains of the pond are white, it is called "the big salt of Hedong". The pickles pickled in the pond salt are beautiful in color and taste, and they will not rot for a long time.

There are also pond salts in border counties. For example, Wuyuan County has two salt ponds of Bai and Wu.

These salt ponds were also the focus of the Hu people's plunder.

China is a country based on agriculture, and since ancient times, water, drought, and locusts have been listed as the three major evils. "The Book of Songs: Xiaoya" has a record of "removing its moth". Teng is a locust.

Locust plagues often go hand in hand with drought. On the one hand, in dry years, locust eggs are greatly increased due to the drop in the water table, the hardening of the soil, and the decrease in water content. At the same time, during drought years, rivers and lakes shrink and low-lying areas are exposed, providing more suitable places for locusts to lay eggs. On the other hand, plants grown in arid environments have a lower water content, and locusts feed on them, growing faster and having extremely high fertility.

Therefore, since ancient times, there has been a saying that 'locusts are in the dry pole'.

The locust plague has spread extensively. The grasslands were also affected. Therefore, Xianbei, who is often only old in Koubian, plundered the border counties this year in the spring and summer when he should have accumulated horses and raised fat.

Xia Yu, the captain of Wuhuan, saw the fighter plane that flashed in this crisis. I want to take advantage of Xianbei and weakness to pacify Saibei in one fell swoop.

In the protracted war with Xiqiang, Xianbei and Wuhuan, our dynasty has sharpened a group of loyal ministers and famous generals. For example, "Liangzhou Sanming": Huangfu Gui, Zhang Huan, Duan Xi. Not only are these three very talented, but a group of adjutants and generals under their command are all generals. Xia Yu is one of them. Xia Yu was Duan Xi Hu Qiang Sima in his early years, and he made many military exploits, and he was the Taishou of Beidi County in Liangzhou when Xia Yu was in Xiping. Xianbei Kou Beidi, Xia Yu pursued and broke it. Captain of Wuhuan was sealed.

Liu Bei asked Wulian, at this time, the grassland that should be green grass is not growing at all. All the seedlings were eaten by the locusts. The locust plague in the seven states of the Han Dynasty, the imperial court opened a warehouse for disaster relief, and the peasants may be able to live. However, the grassland herdsmen, if they have no cattle and sheep, can only starve to death. The reason why Xianbei made an exception to attack in April shows that the situation is urgent.

Just like Zuo Feng's secret letter, this battle is inevitable.

Thinking of this, Liu Bei hurriedly took out the topographic map scroll and observed it carefully.

He also summoned his henchmen Huang Zhong, Xu Rong, Wu Lian and others to ask: If you are a general, how should you enter the army?

Xu Rong crisscrosses Liaodong, and the terrain of the border counties is in his heart. This said: After Tanshi Huai unified the Xianbei tribes, he divided the territory into three. The east of the right Beiping is the east, the right Beiping to the upper valley is the middle, and the west of the upper valley is the west. If I am a general, there are three ways to be a soldier: to make an army out of Daijun, an army to go out of Yunzhong, and then an army to go out of Yanmen. Three ways go hand in hand, go straight to the royal court!

Liu Bei hurriedly took the lamp to see.

Three hundred miles north of Gaoliu County in Dai County, it is where Xianbei Wangting Danhan Mountain is located!

In other words, Xianbei copied the edge in the south, rejected Ding Ling in the north, and attacked Wusun in the east. According to the hometown of the Xiongnu, more than 14,000 miles from east to west, more than 7,000 miles from north to south, covering mountains, rivers, rivers, and salt ponds. Such a huge territory is just in the middle. Why did you put the royal court in Danhan Mountain, which is so close to my Han?

Seeing that Liu Bei seemed puzzled, Xu Rong explained: There are three things that the Hu people rely on: water and grass, shear, and salt land. And these places are all counted. And the location is fixed, all close to my border.

That's why. As soon as the two Han Dynasty came, they often used the Hu people as their guides, or through the border people who knew the Hu language to provide information, and the imperial court used cavalry maneuvers to carry out rapid and accurate decapitation operations on the Hu people's garrisons and eliminate the opponent's living forces. It is called: pounding the nest.

Take the meaning of smashing the enemy's nest directly.

Xu Rong said again: It is expected that the imperial court will make a nest attack this time!

I see!

Because of the strategy of pounding the nest, and because of the sandalwood acacia, Xianbei is divided into eastern, central and western parts. Therefore, the troops must be divided into three ways. All of them are big men riding fine horses. Galloping day and night, but if there is a way to break the enemy, you can go straight to the enemy's nest. If you can kill Hu Sheikh Tan Shi Huai, Xianbei will be chaotic. After the split, Xianbei was no longer able to fight against the Northern Xiongnu and the Wuhuan of the three counties, which were Hu people who belonged to the Han court.

It makes sense to do so.

But if you can't fight quickly, you will be hit with one blow and fall into a protracted war. Now the Han Ting with internal and external troubles cannot support it at all.

Xia Yu, the captain of Wuhuan, said: "Please recruit the soldiers of the counties of Youzhou to attack it, and the birds will be wiped out in the first winter and second spring." "It is also limited to this battle within one year of 'one winter and two springs'!

In this way, it must be a nest strategy.

Seeing that Huang Zhong was silent. Liu Bei then asked: What does the father-in-law think?

Without waiting for Huang Zhong to speak, Wu Lian shook his head: "This strategy is dangerous. ”

Liu Bei hurriedly asked: Why?
