Yanmen Pass, one of the border cities of Great Xia, is a plain outside Yanmen Pass, and further north is a river, named Yinma River, also known as Wuding River, Wuding River is because this river is often fought over by the two countries of Great Xia and Dayan, and there is no definite belonging, so it is also called Wuding River.

The herdsmen of Dayan will graze horses in the upper reaches of the Yinma River, and the farmers of Daxia will use the river water to irrigate their crops in the lower reaches of the Yinma River......

They cross the river when they do something.

In winter, the river will freeze, and it is also the time for the big swallow to hit the grass valley. This time period is very suitable for Dayan's cavalry to fight, because the Yinma River is the natural barrier of Daxia, and after the Yinma River freezes, Dayan's cavalry can come directly from the other side of the river, and a part of the plain area in front of Yanmen Pass cannot stop Dayan's cavalry at all.

Despite this, winter is still a frequent time for small-scale battles, and Dayan will not easily launch large-scale wars, but it is still possible for small-scale cavalry to rob. And the emperor of Great Xia is still grumpy, the previous emperor is also grumpy, and the generals of the border pass are even more grumpy, never said that Dayan's cavalry came to rob him and let him rob it, although the loss of funds generated by the battle was greater than the loss of being robbed by Dayan, but for many years, whenever Dayan's people came to fight the grass valley, the garrison of Yanmen Pass in Daxia was always hard to go back.

The plain area is suitable for cavalry combat, but the handicraft of Daxia is relatively developed, and all kinds of equipment used for combat are taken out, and Dayan can be regarded as being able to fight. And Dayan insisted on fighting the grass valley every year, in addition to being forced to be helpless, there was no intention of testing the combat effectiveness of the Great Xia army, if Great Xia was weak, it must not be a small fight of the small-scale cavalry, but a large-scale and all-out war!

Of course, if they can't grab a little thing back every year, Dayan won't come every year, and they do not have enough food to survive the winter, but they can't save enough food by robbing, so they mainly rely on buying and selling Dayan's grain.

However, the two sides are not friendly countries, they fight every year, and the hatred between the two sides is almost irresolvable, so if you want to buy food from Great Xia, it is impossible on the surface, and the people of Dayan come to buy food from Great Xia? Isn't this looking for death? Therefore, only the smugglers of Great Xia can transport the grain to Dayan.

Although the two sides are belligerents, the merchants of Great Xia have a very high status in Dayan, and the people of Dayan will not and dare not rob the goods of the merchants of Dayan, but will secretly provide protection. This can only show that the people of Great Yan are actually definitely not barbarians, they are very smart, and they know that if the merchants of Great Xia are hurt in Great Yan, or do not get enough benefits, then there will be no merchants coming again, so the merchants of Great Xia sell grain to the people of Great Yan at a very high price, and the people of Great Yan have always bought and sold at a price.

And Dayan's cheap beef and mutton and the fur of various beasts are very popular in Daxia, so that the smuggling merchants can make a lot of money, so although the imperial court explicitly prohibits it, there are still so many profit-seeking merchants, and the smuggling merchants have something to do with the bigwigs at the border, otherwise, this city gate will not be able to go out, and how many interests there are are in it, it is self-evident.

However, recently, the smugglers in Yanmen Pass have a bit of a headache, and their goods can't get out of the city gate at all, because there is one more soldier guarding the city, who looks small, but he said that if he is not allowed to leave the city, he really can't get out of the city.

The little city defender was naturally Chu Yun, and after he came to Yanmen Pass, he was transferred by Zhou Poyu, the guard of Yanmen Pass, to guard the city gate. Chu Yun could feel that this general was a little cold to him, it stands to reason that it shouldn't be like this, although he lost the letter from Chu Shen, but after proving his identity, Zhou Poyu should be enthusiastic, for example, to get him a more comfortable job. After all, the guard before Yanmen Pass was Chu Shen, and Zhou Poyu was Chu Shen's former subordinate.

The selection of general generals will not be in this situation, for the royal family, this can easily lead to the military power of a place is not easy to control, but Zhou Poyu is as his name suggests, very capable, this Yanmen guard general, he is the only one.

Before Chu Yun met with this Zhou Polu, he remembered Chu Shen's explanation to him in the capital, saying that this Zhou Polu was extremely capable and had a very bad temper, but he would give him face. Therefore, after proving his identity, Chu Yun treated Zhou Poyu as a nephew as a son and nephew as requested by Chu Shen, and called Uncle Zhou, but as a result, he was scolded......

"This is a barracks, not a place for the heirs of powerful people like you to drill the barracks, in the barracks, you want to call me a general!"

Chu Yun's heart at that time was simply 10,000 sentences, at that time, he and Zhou Poyu were two people staying in the barracks, and they retreated left and right, otherwise he would not have called someone uncle, but he was still scolded like this, and Chu Yun had to suspect that Zhou Poyu was targeting him.

Zhou Poyu had a reason to do so.

Then, Chu Yun was assigned to guard the city at the city gate, so he was restless.

The goods to the north, all those with grain, salt, and iron, are all forbidden to appear on the camera, Zhou Poyu dared to scare Chu Yun, but the captain of the city defense team who knew Chu Yun's background did not dare to provoke Chu Yun, although Chu Yun was only a soldier under him.

And Chu Yun's refusal to let the goods appear on the scene is also in line with the laws of Great Xia, but it is their behavior of releasing water, if they are poked out by Chu Yun, everything will have an accident, so Chu Yun will not let it, and no one dares to let those goods go.

Those smugglers were really angry, and they couldn't wait to find someone to abolish Chu Yun, but when they inquired, this was terrible, Brother Gongzi from the capital, if he died, it would be a lot of fun! Therefore, the smugglers in Yanmen Pass united and prepared to say good things to Chu Yun.

To put it bluntly, it's a bribe! And the reason why Chu Yun is doing such a thing is to wait for their bribes! Otherwise, wouldn't it be death to cut off people's wealth?

The history studied by Chu Yun is the history of the nation, although it is not a time and space, but there are similarities in history, so when she was assigned to the city gate guard, Chu Yun was annoyed that Zhou Poyu gave her too hard work, and she was blowing a cold wind to work every day, but she was also happy that her development opportunity had come!

Because the defenders of the city have enough oil and water! But the newcomer can't take the initiative to ask for benefits, and he will be despised if he can't say it, so Chu Yun showed his ability to sabotage, although it was a small one, but he definitely won't die......
