Although if the sea wolf sells grain to Jiannu, it will get extremely high profits, and now the price of Jiannu sitting on the ground to buy grain has been as high as a dozen silver, and the grain is transported from the south to Liaodong by sea by sea, and a stone of grain can earn at least ten taels of silver, and this boat of 100 tons of grain can earn tens of thousands of taels of silver.

However, Yu Xiaotian strictly ordered his subordinates in charge of this matter not to sell a single grain to Jiannu, but only to sell tea and salt and other commodities to Jiannu.

Jiannu itself does not know how to make salt, and the weather there is very cold, and the cost of boiling salt is also very high, so the salt they eat is mainly dependent on imports, so salt is also a commodity they need very much.

For tea, although the consumption of Jiannu is not much, but salt tea these two things, their allies Mongolian tribes are very needed, after Jiannu gets these salt tea, they sell it to the Mongolian tribes, and they can make a lot of profits, so these two commodities are still quite popular with Jiannu.

But things like glassware and soap soap, which are still luxuries, are not needed by Jiannu, and their nobles are limited in number, even if they want, they only need a very small amount, and in order to solve the problem of eating, Huang Taiji strictly ordered that luxury goods should not be imported for personal enjoyment, so these fist products of the sea wolf have become chicken ribs among the items traded with Jiannu.

However, things like some daily ceramics are still relatively popular, in order to further open up trade routes and earn more profits from Jiannu, Yu Xiaotian thought about it again and again, and finally approved the export of some Indian cotton cloth or Songjiang cloth that is currently unsalable in the south to Jiannu.

In this way, the trade between the two sides was immediately in full swing, and there were often ships coming from the south to stop in the Denglai area, and then continue to sail north to the Liaodong area to trade with Jiannu.

But in exchange, let Jiannu take all the real money to buy these things, but it is not realistic, because Jiannu does not have so much cash on hand, so the two sides finally discussed, Jiannu will pay part of the cash to buy materials, and the rest of the money will be exchanged with some iron ingots and local products such as tiger bones, deer antlers, ginseng, Korean ginseng, mink and other specialties from Liaodong, and the price agreed by Jiannu is not high.

Drugs like ginseng, Daming is in great demand, in the south of the whole medicine shop now, ginseng is basically priceless, the price of a pound of ginseng, as high as a hundred taels of silver, so it is difficult to find a ginseng.

However, the price negotiated between the sea wolf and Jiannu, a pound of ginseng, was only seven taels of silver, and after being transported back to the south, it could immediately earn more than ten times the profit.

Therefore, this kind of trade is also very cost-effective for the sea wolf, and the sea wolf trade personnel also proposed that they can be exchanged for raw mouth, and one stone of grain can be exchanged for two Han slaves from the hands of Jiannu.

Every time Jiannu enters the customs, a large number of people will be taken captive, and most of them are women, mostly young and strong men, all of whom are good laborers, but because of the lack of food outside the customs, these slaves who were taken out of the customs have a very poor quality of life, and it is not easy for Jiannu to feed them, even if they are given the worst things to eat, they must be something that can be eaten.

Therefore, Jiannu didn't care too much about exchanging the population for salt, tea, cotton cloth and other things, so the two sides also reached an agreement in this regard, every month, Jiannu would provide hundreds of raw mouths to the sea wolf personnel who used to trade, and then be transferred back to Denglai or Jeju Island by the sea wolf for resettlement.

These slaves who were exchanged back, when they set foot on the homeland of the customs again, many of them cried loudly, and when they were outside the customs, they were all slaves who were treated as pigs and dogs, and they were not as good as dogs, not even pigs, not to mention the clothes they wore were good, and many of them were not even covered in the cold.

Now that they have been exchanged for the sea wolf, although they are still slaves, everyone has been given new clothes, they can wear warmly, and although they still eat multigrain cakes, they are already better than when they were outside the gates, and many people still feel like a dream until this time, and they can't believe that this is true.

Even if it is to be a slave to the new masters of the sea wolf, it is a thousand times better than to be a slave to the Jiannu, so when they are brought back, they are grateful to the new masters of the sea wolf, and they are extremely deferential.

These people are regarded by Yu Xiaotian as the seeds of the future counterattack on Liaodong, everyone here has a bitter hatred for Jiannu, as long as they are well raised, they will be trained into an army in the future, and when the time comes to attack Jiannu, these people will definitely not show mercy.

At this time, Yu Xiaotian specially approved the establishment of a new battalion on Jeju Island, which was specially responsible for absorbing these Liaodong Han people who had been gathered from Guanwai and Shandong, and trained them into a northern army, just waiting for the future to be put into the northern battlefield.

Jiannu probably never imagined that they would trade with the sea wolf, and these slaves handed over to the sea wolf would become their gravediggers in the future, if Huang Taiji knew that Yu Xiaotian was doing this kind of plan, I am afraid that he would kill him, and he would not do such a deal with the sea wolf.

Of course, doing business with Jiannu is not smooth sailing, many powerful people in Jiannu are quite arrogant and vicious, many Han businessmen who used to do business with them, and they have shipped goods outside the customs, and many people's goods have been embezzled by these Jiannu magnates, and there are many people who have lost their money, and even killing people and selling goods are really normal.

Therefore, in the early days, the ships that used to trade also encountered some difficulties from Jiannu, and there were even cases of Jiannu trying to loot ships and goods.

The Seawolf's cargo ship was not a vegetarian, and the people on board were all naval reserves, and the ships were equipped with a lot of small and medium-caliber guns, and they were also armed with a lot of muskets.

In such a situation, the captain of the ship would not sit idly by, and even if he gave the order to open fire, the guns and cannons on board would turn the Jiannu who had tried to rob the ship's cargo on their backs, leaving the corpses on the ground.

Jiannu immediately learned to be obedient at this time, knowing that this sea wolf could not be provoked, people had sharp guns on hand, and if they wanted to bargain on their hands, they had to pay the price of blood, and after the accident, Jiannu Huang Taiji heard the news and immediately sent someone to inquire, and learned that it was their people who were plotting against him, and he was immediately furious.

Finally, now a group of sea wolves are willing to do business with them, but some people want to make personal gains, and if they don't do so, they will cut off this trade route, so Huang Taiji immediately ordered the execution of a few guys led by them, which can be regarded as completely suppressing those Jiannu who tried to plot against the sea wolf's ships.

Moreover, since this incident, whenever the ships of the sea wolves dock for trade, Huang Taiji has ordered the Jiannu troops stationed at each trade point to provide protection for the ships of the sea wolves, and also provide support for the ships of the sea wolves.

This trade route, although for Xiaotian, the profits earned are nothing in the profits he earns every year, but it also makes Yu Xiaotian initially build an intelligence network in the Liaodong area, and he can collect some information about Jiannu.

In the ninth year of Chongzhen, Jiannu waved his army to break through the pass and went south to the land of Gyeonggi to raid and plunder, a certain kind of Cheng dù had a little to do with the trade of the sea wolf, in order to exchange for more materials from the sea wolf, they did not have enough cash on hand, and the number of raw mouths available for trading was not much, so they could only find a way to rob the Ming again.

This prompted Jiannu to rush into the pass as soon as Huang Taiji ascended the throne and became emperor in the ninth year of Chongzhen, and rushed into the pass to loot it.

In this year, Jiannu entered the customs and robbed more than 100,000 people in the Gyeonggi area, as well as various goods, which were converted into more than 700,000 taels of silver.

In such a situation, although the impeachment of Xiaotian between the government and the opposition has been higher and higher, Chongzhen is currently in a state of anxiety by Jiannu and the Wandering People's Army, and he has no energy to think about how to deal with Yu Xiaotian, so this matter has dragged on.

When Chongzhen's tenth year came, Yu Xiaotian made a count of the strength of his hand, and at present, the strength of the three major fleets of the Yu Jiajun Navy has reached more than 20,000 people, and there are more than 300 medium and large warships, and the number of fast and light sailing ships such as various anti-smuggling ships and smuggling boats, as well as the fishery supervision clippers who are responsible for monitoring the fishing grounds and collecting taxes at sea, the number is as high as nearly 1,000.

Now the first fleet of the sea wolf, has been in the family army sequence, was officially renamed the Northern Fleet, under the order of Xiaotian, the fleet was moved to Fushan, that is, the Qingdao port in the later generations, and truly formed a control over the northern coastal area, the responsibility area includes the entire Shandong coast, the Bohai Bay area, to North Korea and even the sea surface around Jeju Island, all belong to the Northern Fleet responsible for control, and they are responsible for handling something.

The Second Fleet, on the other hand, was responsible for the coastal areas of Fujian, Zhejiang, and Nanzhili, and the fleet's home port remained in Weitou Bay for the time being, but it actually controlled the Dongtou Islands off the coast of Wenzhou Prefecture, and stationed a detachment there, using the Dongtou Islands as a base to control the coastal areas around Zhejiang.

In addition, the Zhoushan Islands outside Hangzhou Bay have also been actually controlled by the Yu family's army, which used to be a gathering place for pirates, and it is also a gathering place for maritime smuggling in Zhejiang.

So a few years ago, Yu Xiaotian instructed the navy to begin to infiltrate there, and soon in the name of a group of pirates, it rose in the local area, quickly killed a large number of local gathered pirates, integrated various forces there, and then controlled the entire Zhoushan Islands in the hands of the sea wolf, until the control of that side was completely completed, and some people knew that the newly rising group of pirates over there turned out to be the people of the sea wolf, but it was too late.
