Many people have forgotten about one force in the past few years, and that is Houjin.

Since surrendering to the Ming Dynasty, becoming a vassal and demoting themselves to the tribal level, the Houjin is at least not too miserable, at least the Ming Dynasty has rewarded them with the position of Tusi.

It's just that so many years have passed, and they naturally don't have any gratitude to Daming in their hearts, on the contrary, their hatred deepens as life gradually embarrasses.

This is not surprising, in the past, they could continue to go south to plunder the people of the Ming Dynasty, and then produce for them as an effort. And they only need to continue to learn the ability of riding and shooting, and the so-called wealth will be handed over to the minions to produce.

Since the surrender, they have no way to go south at all, Daming's firearms are becoming more and more advanced, and the cost of going south is getting bigger and bigger, which is not cost-effective. If you can't catch slaves, you will naturally not be able to produce wealth, and even if there are some slaves originally, slaves will give birth to new slaves, but the Manchu people will also increase.

As a last resort, in recent years, they have only been able to develop in the direction of Mongolia.

In line with the idea of the Mengman family, the Agobeles of the Later Jin Dynasty married the daughters of the Mongolian tribal patriarchs, and then married their own princesses to the Mongolian young patriarchs. Through a series of marriages, the two sides quickly merged together. Of course, the so-called Mongolia here is the part close to the Houjin, and to the west, there are more Mongolian tribes in the diaspora, at least today's Mongolia, has not yet formed a strong centralized regime.

At this stage, the slaves of the Later Jin Dynasty came from this part of the Mongol tribes. Together with the allied Mongol tribes, they went west to hunt and conquer more than a dozen large and small tribes, but the captured population was still too small. So Houjin had no choice but to explore the north appropriately.

In the north, there is no other existence except for some remote Jurchens, and they are very rare. After a long time, it loses the meaning of exploring.

In the end, he chose the old way, moving eastward and attacking North Korea.

It seems that the Ming Dynasty acquiesced in this kind of attack between the states, as long as the Houjin did not occupy too much land in Korea, and caused others to come to the door to say that the Ming Dynasty was the suzerainty but did not help the vassal states, then it would be acquiesced.

Huang Taiji completely grasped this mind of the Ming Dynasty, and only plundered a large number of Koreans and gold and silver treasures each time, but did not occupy an inch of North Korea's land. This made North Korea cry to Daming several times, but Daming remained silent.

After several plunders, Houjin has somewhat recovered some vitality and abundant resources.

The most important thing is that Hou Jin and Zheng Zhilong have a relationship. It was a fleet of ships that came to North Korea to do business, and they hooked up together.

Mr. Chung needed a variety of North Korean specialties, including some of the more expensive furs, wood, and ginseng. Of course, the animal husbandry business can also be used, but it is only a war horse business. It's not that nothing else can't be earned, but the profit is too small, and the space occupied by animal husbandry is too large, and the preservation of raw meat is a big problem, so I simply don't do it.

War horses from Houjin and Mongolia can still be bought at a good price, especially in the south where there are no horses, a scout cavalry or a handcuff cavalry is the dream of all forces, but there is nothing to be done because of the lack of war horses.

Zheng Zhilong saw this business opportunity and made a deal with Houjin, trafficking horses to the south for sale in exchange for 300% of the profits.

As for the remarks of doing business with the enemy chieftain, with the return of Houjin to the Ming Dynasty, there is no worries. Everyone only sees the immediate benefits, and does not care about the long-term problems, and perhaps no one will believe that Hou Jin's ambitions are so big that he still dreams of going south to invade China again. Of course, it's not too big to say big, at least Houjin still has the ambition to annex the whole of Huaxia, after all, they don't have the strength to do so.

The deal with Zhang Hongbin is still ongoing. The Republic also needs a lot of meat, and the Mongolian side is the best source of meat, and war horses can also be used, as scouts and messengers. Especially with shotguns, the musket cavalry is also fully capable of being formed. Not to mention ginseng or something, the ginseng of Changbai Mountain has always been of good quality.

Because of this, Hou Jin also bought a large number of firearms and ammunition through Zheng Zhilong and Zhang Hongbin. After the armament was completed, the war against Western Mongolia and East Korea continued. While expanding westward, he also drew nutrients from Korea.

It's just that there is a problem recently, that is, the western border of North Korea is getting less and less nutritious, and the people are becoming more and more clever.

They often hide in the deep forests or secret hideouts when the army comes, and the warriors of Houjin will not be able to find them. It also means that nothing will be gained from this attack. If you want to get something, you can't do it unless you keep going deeper.

To go deep means to pay the risk of being ambushed or surrounded. Even if North Korea's firearms are very poor, even if North Korea has been beaten by itself, Huang Taiji does not dare to take this risk with Houjin's warriors. But if he doesn't continue to invade, he won't gain anything......

Therefore, Huang Taiji is also having a headache at this moment.

"Xiandou, now our development has reached a bottleneck...... If you continue, you can only slowly deplete Houjin's vitality. Can you sue me what we should do? "By Huang Taiji's side, the best strategist is Fan Wencheng.

"If you want to develop, you have to go west or east. The western part of the country is vast and sparsely populated, and it is not interesting to occupy it. So keep heading east! Fan Wencheng seemed to have an idea and replied respectfully.

"To the East...... Xiangdong is too dangerous, we have to take care of Daming's thoughts...... "Huang Taiji is also depressed, depressed about how his power is developing so slowly.

It's not that he doesn't want to develop industry, it's that Houjin simply doesn't have the basis for developing industry. Even though he has recently made many Manchus start farming and learning skills, this kind of people are mainly hunting people, and they are not interested in these two. Even if you change jobs, the learning speed is slow. All the scientific research work is pressed on the Ming craftsmen, and even if Huang Taiji has a clear reward system, there is still no way to improve the efficiency of research.

Not to mention, Houjin is located in a cold place, and there are no resources at all, and even if they do, they will not mine, and can only mine the kind of minerals in the open pit. As a result of the lack of raw materials, many of them need to be considered, otherwise they will have to wait for the next batch of materials to arrive. Speaking of this, Huang Taiji is also very envious of Zhang Hongbin, scientific research experiments can be tried and tried without restraint, and he is not worried about the scrapped part at all.

"If it had been a few years ago, I might have been scared. But now, even if we don't go south, we don't have to worry about going north. Fan Wencheng said with a smile.

"What do you mean by that?" Huang Taiji immediately became excited.

"Da Ming is busy revising the constitution at the moment, and it seems that he is learning the administrative model of the republic. It will take them a few years to get used to this pattern. Of course, this is not the point, the most important thing is that their reforms and changes have touched the fundamental interests of the local gentry, especially the big landlords, and they have to spend a lot of energy to rectify them, so they have no time to care about other things.

Others occupied the world first before they began to develop, but the Republic and the Ming Dynasty were very stupid, they expanded while developing, and the result was that they were held back by a steady stream of political problems and could not get out.

Besides, we have accumulated a lot of firearms and ammunition in recent years, and it is still possible to really fight a garrison battle with Daming. With the current situation of the Ming Dynasty, it only needs to maintain an undefeated battle, which is enough for them not to dare to go north. And we can go down the east and occupy all the land we need to occupy! Fan Wencheng analyzed it seriously.

"Haha, Xiandou, you are really my Zhuge Liang!" Huang Taiji was really happy.

"Not only North Korea, but also the Japanese state of North Korea, which looks to the sea, we can also consider ......," Fan Wencheng said more vigorously.
