It is Shitou Mandanyu's son Mao Dunzheng who is the king of Zuo Xian.

The Huns are different from the Central Plains countries in that they respect the left, and the position of King Zuo Xian is usually held by Shan Yu's heir.

Only a hundred years later, King Zuo Xian often died of unfaithfulness. The Xiongnu thought that this title was unlucky, so he changed it to "protection".

Zuo Xian Wang Mouton reminded his father:

"Shan Yu, I wait for the battle to rob livestock and property."

"Yunzhong County is full of wasteland, and Qin people's own food must be transported from the Central Plains."

"When we attack Yunzhong County, what else can we gain besides losing a large number of warriors?"

Tou Mandan answered disapprovingly:

"Grassland, a large grassland."

"The Hetao Plain is right by the Yellow River and the climate is warm, the grass is fertile and the water is beautiful and suitable for grazing..."

"If we can own these two areas for a long time, we can drive cattle and sheep here to spend the winter every year when the weather is cold, and the loss will not be that big."

"What's more, there are only more than 10,000 people in Qin. Do you think we will lose a lot of warriors when we attack the cloud?"

Touman Shanyu was right.

Although the Hetao area is located in the north, the temperature is not low in winter, but compared to the Mongolian Plateau in the north, it is a low latitude, and the Yinshan Mountains block the cold current, so it can become a haven for the Huns in winter.

The Huns’ way of life is a bit like migratory birds... When the weather is cold, they go south and go north again when the weather is warm. They go back and forth every year. No wonder everyone is required to ride horses.

Mouton objected:

"But we have already occupied most of the back and front sets."

"If you are only considering relocation in winter, you only need to hold the existing place."

Tou Man Shanyu shook his head, then spread a sheepskin map in front of Mao Dun and pointed to the location of Yunzhong County and said:

"Yunzhong County is the pedal for the Central Plains to enter the Hetao."

"If we want to have a loop for a long time, or if we don't want to find out that Qin Jun is everywhere when next winter comes next year... we must drive them all out, understand?"

Although what Touman Shanyu said is reasonable, Mouton is not optimistic about this attack.

It's not clear why Maurton is, maybe it's an intuition with some analysis...

Mouton didn't think that the Qin people were bluffing.

Mouton used himself to save people. He thought that if he were standing in the position of the Qin general, that is, Shen Bing, he would not give up the entire Hetao and only guard the Yunzhong county so easily.

From this, Mouton thought that sinking soldiers was not easy.

But at this time, Mouton was unable to prevent Shan Yu from playing, so he could only be careful with reservations.

In fact, Mouton's ability and talent are indeed stronger than his father Tou Mandanyu.

It's just that in the end they turned their eyes on each other...

Touman originally hoped that Mouton would continue his single position, and there was no problem at this time.

However, after Touman married the Que clan, he wanted to make the child owed by Que succeeded to the throne of King Zuo Xian, so conflicts arose.

Touman Shanyu played a sorrowful operation. He first negotiated with Yueshi and took Maodun as the quality... This is normal, and it is also popular in the Central Plains countries. The prince as the quality means that he will not betray the covenant, otherwise the prince will Life is not guaranteed.

Mouton did not doubt that he had it, and went to Yueshi alone.

Whoever wants Tou Mandanyu to get rid of Maodun with Yueshi... As soon as Maodun's front foot arrived at Yueshi, Tou Mandanyu led his troops to the crime.

As soon as Mouton heard the news, he realized that something was wrong, and immediately stole the horse and escaped from Yueshi.

This is mainly because the nomadic people’s city is not strictly guarded, and even Yueshi didn’t expect that Tou Mandan would overthrow the covenant so soon and there was no news, so he didn’t react at all and didn’t come in a hurry. Dun managed to escape.

After Mouton fled back to the Huns, he no longer had any hope for Mandanyu.

This servant is also a cruel master. In order to make his subordinates obey orders firmly, he always experimented with things he liked...

He ordered his subordinates to shoot wherever they fired. Otherwise, they would be punished as a death penalty for defying military orders.

Shoot the birds and beasts first, there is no problem.

Then came Maodun's love horse, someone who dared not follow, was immediately killed by Maodun.

Then came Maodun's beloved wife, someone who dared not follow, was killed by Maodun again.

This way the subordinates will know it, anyway, it's right to shoot wherever he points, otherwise he will only die.

then.

Mouton shot at the head when he was out hunting, Mandanyu...

This is the allusion of "Ming Di and slaying his father". After that, Mao Dun led the Xiongnu to conquer the north and south of the desert. Even Liu Bang was defeated by him and had to bow his head and proclaim himself in exchange for peace on the border.

Touman Shanyu’s offensive plan is simple:

With 10,000 horses led by the right sage king to attack frontally, Zuo sage king Mouton used five thousand horses to cut into the Qin army’s defense line along the Yellow River to outflank the Qin army...This is a common tactic of the Huns, even if it arrives. During the Mongolian period, it still used mobility to divide and encircle the enemy.

But the tactics do not need to be repeated, as long as they are easy to use and can kill the enemy.

The news soon reached Shen Bing.

Shen Bing is now planning the irrigation of the enclosure.

Irrigation is not just a matter of opening an artificial river and then introducing it into the field or adding a few waterwheels.

This model is indeed feasible in rainy and humid areas, but it will cause problems in dry and water scarce areas.

The reason is that there is a large amount of evaporation in arid and water-deficient areas, and the flood irrigation method commonly used by the people will make the land salinized and reduce fertility.

As mentioned before, the water is full of salt. After flooding, the water evaporates and the salt remains in the land. It accumulates year after year. After decades, the land will be salinized and no grass will grow.

The modern solution is to use sprinkler irrigation and drip irrigation, that is, directly irrigate the roots and leaves of the crops with the least amount of water to satisfy the growth of the crops...Most of the water is absorbed by the crops, and there is very little water left in the land, which is salinized. The speed is greatly reduced.

Due to limited productivity, Shen Bing could not use this method for irrigation.

What Shen Bing can do is to dig as few canals and ditches as possible, and use bamboo tubes to divert water into the fields to prevent water from infiltrating the soil during the transportation process and causing unnecessary loss.

Shen Bing left it to Shu to complete this aspect.

Fortunately, when Shen Bing came out of the artillery division, he selected talents in all fields. Now in Yunzhong County, there are people responsible for all aspects.

Just then, Cheng entered the account and reported:

"General, the Huns are a little bit moving, it seems they are about to attack!"

Shen Bing only nodded and replied:

"Got it."

Shen Bing thought that this was just Ren and the others chasing after the storm, he always thought that the Xiongnu had no reason to attack Yunzhong County.

However, when Wang Ben brought Wang Bai and Lei Hui to find it, Shen Bing found out that this might not be the case...
