Three hundred years ago, the Jin dynasty crossed to the south, taking away not only the wealthy families in the north, but also the advanced production technology and farming equipment in the north, which made the farming in the south of the Yangtze River suddenly change from slash-and-burn farming to the most advanced place in Chinese agriculture.

On the contrary, the farming culture of the north has been severely damaged by years of war, and it is only now that it has gradually recovered, but in terms of farming technology, the south has shown a leading momentum, after all, the nomads in the north themselves lack management experience in farming.

After Yu Wenxian lost the two main agricultural lands of Guanzhong and the Central Plains, if he wanted to maintain a sufficient amount of grain, he had to improve his grain production efficiency.

Funnily enough, Li Xinchen has enough technology, but there are not enough people, which makes the amount of grain produced in the south cannot be compared with the north after all, so Li Xinchen also hopes that the two sides will exchange markets, in order to make up for the pressure on food demand brought about by the rapid population growth of the Han Dynasty.

Of course, food is only one of the reasons, in addition to this, there are all kinds of equipment needed in the north, especially for war. With the advent of gunpowder, the Han Dynasty began to gradually focus on the research and development of related weapons, and the bows and trebuchets that had been developed before were actually no longer considered advanced equipment, so it was not impossible to sell them at a reasonable price to make extra money.

As for Li Xinchen, if he wants to really compete with Yang Jian now, he still needs a large number of war horses, but the northwest has not been in Li Xinchen's hands for a long time after all, and it is difficult for Li Xinchen to obtain a large number of horses in a short period of time through the northwest.

Cavalry is never a good class to cultivate, and after obtaining enough horses, it is necessary to select men and conduct all kinds of training to be able to train an ordinary foot soldier into a qualified horse warrior. In this regard, the farming people have a natural disadvantage, for the peoples on the grassland, they are originally a people on horseback, they have lived on horseback since childhood, and naturally do not need additional training.

The formation of a qualified cavalry is less than a year, and at most two or three years, and now Li Xinchen can no longer wait for the Northwest Horse Farm to send enough war horses, so that when the cavalry is trained, the daylily will be cold, so Li Xinchen must also try to get more war horses from Yu Wenxian.

In fact, this time Yang Jian and Yu Wenxian went north to drive out the Turks, in fact, there is another purpose, that is, to be able to occupy more northern horse farms, especially for Yu Wenxian, who has a huge number of Xianbei cavalry under his command, having a horse farm can naturally ensure the continuation of this cavalry, otherwise as long as the war horses have no source, then even if there are more cavalry, what is the use?

This mutual market is obviously a rare opportunity for both sides. And for the two Huai, who have been divided and antagonistic for hundreds of years, this is also an opportunity to melt the ice.

Of course, the southern businessmen who have been gearing up for a long time are also counting on being able to rush into the broader northern market through this time, you must know that when the south has begun to establish a complete money system, the government's supervision and participation in commerce and trade are rising rapidly, which means that there is less and less room left for these businessmen to obtain huge profits and even seek more benefits.

No one was better able to grasp the trends of business and economic development than Li Xinchen, who was completely familiar with the way finance worked in later generations, so in the south, businessmen found themselves in the almost seamless rules that Li had laid down, and could no longer seek the opportunity to get rich overnight as before.

The north is different, now the north is almost still in the most primitive stage of independent business, and it can even be said that it is a blank, these merchants rush into the northern market, and naturally they will no longer be bound by the laws of the Han Dynasty.

However, everyone also knows that Li Xinchen intends to use the merchants as gunmen, and through them to occupy the grassroots market of the Northern Zhou Dynasty first, it is equivalent to occupying the lives of the people of the Northern Zhou Dynasty. When the people of the Northern Zhou Dynasty were accustomed to using the goods of the south and trading with the southern merchants at fair prices, the northern merchants would naturally be attacked and annexed, and the large and small families who had lost the support of the grassroots people and had an inseparable connection with the merchants were all attacked, and the rule of the Northern Zhou court would naturally become weaker and weaker.

But this itself is a disorderly process, and even Li Xinchen himself does not know the result, what these businessmen will make things look like is actually Li Xinchen himself is not sure, but at least there is no harm to the big man.

Trade is the most important article of the treaty, and the rest of the two sides send envoys to each other, send annual offerings to each other, and so on, in fact, all of them put the two sides on an equal footing.

Being able to achieve such a result in negotiations with Yu Wenxian is actually very satisfying to Li Xinchen. After all, Li Xinchen really doesn't have the strength to go head-to-head with Yu Wenxian now, at least he can solve the Huainan problem for so long, and he can make the entire front come alive.

Xu Shanxin took a deep breath, wrote down his name with a pen, and then handed it to Liu Xiuzheng next to him. Liu Xiuzheng also signed his name as the envoy of the Northern Zhou Dynasty, and then Yu Wenxian waved his hand, and the attendant took the seal of King Qi.

This contract is in duplicate, first stamped with Yu Wenxian's big seal nearby, and then it will be sent back to Jiankang Mansion to be stamped with Li Xinchen's big seal, and then both parties will hold one copy.

Looking at the bright red seal, Xu Shanxin's hand trembled slightly, and then the whole person relaxed.

I wonder how long peace between the two sides can really be maintained after this peace treaty is signed?

Moreover, since Li Xinchen and Yu Wenxian have made a peace treaty, it means that the Han is about to sharpen his knife and Huo Huo will make a move on Yang Jian.

War, which should break out soon.

Seeing Xu Shanxin leave quickly with the peace treaty, Yu Wenxian in the council hall also breathed a sigh of relief, although the two sides did not clearly explain the peace treaty, but even the most tense Lianghuai front line has become a place of trade, so it means that Li Xinchen acquiesced to the fact that the two sides now have a common enemy.

"Yang Jian, this time the king wants to see what you use to deal with such a situation." Yu Wenxian said with a sneer.

And Liu Xiuzheng next to him frowned slightly, and sighed helplessly.

He had already expected that in this troubled world, it was impossible to really avoid all wars, and the resolution of a war was just to make way for a more intense war.

Even he felt that his ideals were a little too full.

And the reality has always been skinny.

"Brother Xian, stay by the king's side this time." Yu Wenxian said earnestly at this time, "With your help, this king has swept the world, like a tiger with wings!" ”
