The border towns and Mongolia have a long history, and both sides take their own needs. However, such trading has a great relationship with the court's policies. Since the Wanli period, because Nurhaci raised an army to oppose the Ming Dynasty, this trading has basically stopped. Especially after Nurhaci sent troops to conquer Mongolian tribes, the court basically couldn't hear the court talking about trading.

The primary living condition for mutual trading is that both parties can conduct fair transactions in a fixed location. If this foundation is lacking, it is not a transaction. Because of the strength of the Later Jin Tartars, over the years, Mongolian tribes have followed the Later Jin army and plundered deep into the Ming Dynasty for plunder, and easily obtained wealth. There is no need to trade with each other.

The production technology of the Later Jin and Mongolia was very backward. Whether it was grain production or smelting technology, they could not compare with the Ming Dynasty. Therefore, they lacked a lot of things, including grain, iron tools and even weapons. Although they continued to invade the mainland of the Ming Dynasty, including Huang Taiji of the Later Jin Dynasty, they admired the Ming Dynasty very much and admitted in their hearts that the Ming Dynasty was prosperous and progressive, representing the direction of prosperity.

Judging from this situation, it seems that there is no need for mutual trading, but it is not entirely true that the gap between the rich and the poor in Mongolian tribes is even greater. The tribe leaders have a lot of wealth. However, the ordinary herders below are still as poor as they join the army. They are not in the eyes of the powerful and powerful class, and few people notice them that farmers and herdsmen at this level need to trade with each other and exchange them for food through horses, so private trade still exists.

The risk of this kind of mutual market is very high and there is no guarantee. Maybe during the transaction, there will be forced robbery or even murder. Humans will die for money and birds will die for food. Despite many unstable situations, mutual markets will still survive tenaciously because someone needs it.

The profits of mutual markets are very huge. For example, the price of each horse in Mongolia in various parts of the Ming Dynasty is at least fifty taels of silver. A good horse can even exceed 100 taels of silver. According to the grain conversion, fifty taels of silver can buy more than one hundred stones of grain. The grain prices in Shaanxi are high, and rice and wheat are five cents of silver and one stone. However, during the exchange of mutual markets, about thirty stones of grain can be exchanged for a horse.

The price of iron tools is higher. The farmers and herdsmen of Mongolian tribes do not understand smelting technology at all and rely entirely on purchasing these things from the Ming Dynasty. Some farmers and herdsmen with poor conditions pay attention to not using iron pots, but rely on natural barbecue to make cooked beef and mutton, because of the invasion of the Ming culture. Farmers and herdsmen with good conditions have long started using iron pots. This must have affected many families, so the demand for iron tools is huge.

There are also weapons, which are prohibited from trading, but only a genius knows about private transactions.

With these huge profits, there is also transaction. The court cannot prohibit the border troops stationed in the garrison even participate in the transaction and get a share of the pie.

Su Tiancheng has learned about these situations. In less than a month, the information collected through the dark lines fully demonstrated the trading situation in Shaanxi border towns. In this case, King Qin, King Rui and King Han accounted for a share.

Overall, the mutual market is generally under the control of the border army, but because of the weakness of the border army, it is impossible to effectively protect the people of the Ming Dynasty. As a result, the vicious incidents of the mutual market emerge one after another. Some small merchants who joined it even died. The border army of the Ming Dynasty can discover the business opportunities. The leaders of the Mongolian tribes are not stupid, and they can still discover the mystery. During the process of the mutual market, the Mongolian tribes often appear, that is, the Mongolian Eight Banners. The border army is not the opponent of the Mongolian Eight Banners at all, and the people who suffer in the end are still the people.

This situation has undergone a subtle change.

Nothing else, Jiangning Camp came to Shaanxi.

The reputation of Jiangning Camp has been introduced to Mongolia. The 100,000 army led by Ajige entered the mainland of the Ming Dynasty, collided with Jiangning Camp, and encountered an unprecedented defeat. Even Huang Taiji began to notice Jiangning Camp. In addition, Jiangning Camp had just entered Shaanxi and immediately annihilated 100,000 bandits, which even prompted the Mongolian tribes to pay attention.

Of course, the focus here is the order issued by Huang Taiji. The Eight Banners of Manchuria and the Eight Banners of Mongolia were not allowed to enter the pass easily, so as not to encounter the Jiangning Camp and cause major losses.

But such a change is not very obvious. After all, the Mongolian tribes fully feel the convenience of robbery. As long as they send troops to the Ming Dynasty, they can rob them everywhere. The Ming Dynasty's border troops are just decorations.

As the Spring Festival approaches, everyone is going to celebrate the New Year. This is also the best time to rob.

When Su Tiancheng was still thinking about how to carry out a trade, he received an emergency from the border army.

It turned out that as the Spring Festival approached, the annual plundering time was ripe. The leaders of the Mongolian tribe organized an army and began to enter the places where Ningxia's left and right guards and Yulin guards were stationed, plundering property and capturing the population.

The memorials of the border army and the information on the hidden lines were all placed on the desk. Su Tiancheng had read them many times. He had been thinking about whether to send troops to severely attack the arrogance of the Mongolian tribe.

The information on the dark line is very detailed. This time, the Xibe tribe and Dawuer tribe in Mongolia were harassed by the border. These two tribes are very famous in history. During the Shunzhi and Kangxi periods, the Xibe tribe formed the Xibe camp, and the Dawuer tribe formed the Soren camp. The two battalions were the most capable battalions in the Qing Dynasty. The combat effectiveness exceeded that of the Eight Banners of Manchuria and became the pride of the Qing soldiers.

However, these two tribes have not yet formed a strong combat power and are not as famous as that.

The tribes in Mongolia were basically recovered by Huang Taiji and have become places under Huang Taiji. The tribes that Mongolia can fight are mainly concentrated in the Hetao area. They were previously affiliated with the Aoerdusi. To this day, they have long become the biggest threat to the Ming border army. The Xibe and Dawuer tribes are concentrated here.

Mongolian farmers and herdsmen have lived on horseback since childhood. They have superb cavalry, strong combat power and quick action. When the Ming army faced Mongolian cavalry, they did not have any advantage and were almost beaten. However, Mongolian cavalry, like the Later Jin army, have a fatal weakness, that is, they cannot attack the city. Therefore, after they entered the Ming territory, most of them also moved around towns. Perhaps for this reason, the Mongolian army did not have much impact on entering the Ming territory, nor did they attract the attention of the court.

The Ming border army built many castles. These small barriers are called Huoludun. Su Tiancheng once saw them in Northern Zhili. This Xuludun can prevent the attacks of the Tartars, but it also trapped the border army to the greatest extent. To be honest, Huoludun only protects the safety of the border army and cannot protect the people at all.

What can cause shock to the court when the Tartars invaded the mainland is that the city was destroyed, or the fire road pier was attacked or even destroyed in large numbers. As for villages and towns, the people suffered tragic losses, it is nothing in the eyes of a certain senior official of the court.

After Hong Chengchou came in, Su Tiancheng pointed to the memorials and information on the table and signaled Hong Chengchou to take a look.

Half an hour later, Hong Chengchou spoke.

"Sir, are you thinking about attacking the Mongolian army?"

"I'm still thinking about it. It's not easy to attack the Mongolian army. The time is different now. It's the Spring Festival soon. At this time, it will probably cause some panic."

"What the adults said is that this always requires some reason to attack the Mongolian army. I wonder why I am thinking about sending troops. In other words, the Mongolian army is the places where Ningxia Guards and Yulin Guards are stationed, and it has not affected other parts of Shaanxi for the time being."

A smile appeared on Su Tiancheng's face.

"Mr. Hong, you probably didn't notice that the profits of mutual markets are too high. The expenses of Jiangning Camp are increasing day by day. We need a stable source of income. If we can directly control the mutual market, we will have a generous income. For this reason, we must teach the Mongolian tribes a lesson. Besides, I heard that the Xibe and Dawuer tribes are very brave. Let's try it out, how hard their necks are."

Su Tiancheng took out a letter from his arms and handed it to Hong Chengchou.

Hong Chengchou looked at the letter quickly, and the expression on his face gradually changed.

"Sir, I really didn't expect that the profits of mutual trading are so huge, but the court strictly prohibits the mutual trading."

"One time, another time, the imperial court was not allowed to trade with each other, because they were worried that the Mongolian tribes would become stronger, including the Later Jin Dynasty, and the situation was also prohibited. But now, we were not allowed to trade with each other. The army of Mongolian tribes had not yet been plundered in the Ming Dynasty. There were only two ways to prevent such a situation. One was to severely attack the army of Mongolian tribes, to fear them, and even went deep into the Hetao area, and copied their nests to make them afraid of Jiangning Camp, so they became honest. The second was to carry out trade with each other. After all, farmers and herdsmen of Mongolian tribes also had to live, and they lacked necessary daily necessities, so they could not survive. Mongolian farmers and herdsmen had a large number of horses, cattle and sheep, as well as gold, silver and treasures. The focus of the lack was food, iron, etc. As for silk and other supplies, even if they were luxury goods, why not seize such an opportunity to gather wealth."

Hong Chengchou's eyes shining, and trading with each other is a future matter. There is no need to consider it at present. It can be used to attack the Mongolian tribal army, or even to the Hetao area, and to attack the Mongolian tribe's nests. What a spectacular thing this is. Think about the Han Dynasty and Tang Dynasty, Wei Qing, Huo Qubing, Li Jing, and these familiar generals went deep into the Hetao area, and even further away, and severely attacked foreign invaders. They have become famous throughout the ages and become the objects of worship in later generations.
