Of course, Bumu Butai said that Jaisang was sick and could not afford to travel long distances, which is also true.

However, the injuries on Jaisambel have actually been better for a long time, and his real illness is in his heart, that is, "heart disease".

Especially after he received his first letter from Harizula, his heart became "very serious".

Now the future and fate of more than 40,000 people in the Horqin left-wing Mongolian tribes are in his hands.

If one misjudgment or one misdecision, the future and fate of these tens of thousands of people are likely to be buried.

A few decades ago, when the four tribes of Horqin accumulated more than 200,000 people, and when they moved south from further north, not only did the other tribes in the steppe of Eastern Mongolia dare not confront them, but even the powerful Jurchens who have risen do not dare to underestimate them a little.

However, decades have passed, and the more than 200,000 Horqin people who went south at the beginning have not only not increased much, but also seem to have lost a lot compared with the past.

The Horqin left-wing Mongol tribes alone have been fighting for the Jurchens of the Later Jin Kingdom in the past few years, and have followed the Jurchens to fight in the south and the north, and the population and livestock they have gained and the people and livestock they have lost have offset each other, and the total number of men and horses in their departments has dropped a lot, and the total loss has been nearly forty percent.

If, as usual, the Jurchens of the Later Jin State were invincible and invincible, and the losses of the Horqin left-wing Mongol tribes could be compensated or replenished after the war, then everything was okay.

But now, the Jurchen Eight Banner nobles in the Houjin Kingdom can't even replenish the losses of their own Jurchen bannermen and armored people, so how can they give the Horqin people anything to supplement?

Although Zhai Sang did not go to Shenyang City to make a pilgrimage to his brother-in-law and son-in-law, he had a lot of eyeliner in the Khan palace of Huangtaiji.

His sister Zhezhe is Huang Taiji's concubine, and his youngest daughter Bumu Butai is also Huang Taiji's Xigong Fujin.

Not to mention the two women around Huang Taiji, it is the Horqin maid next to these two women who can convey the news that Zhaisang is interested in or not, intentionally or unintentionally, back to the ears of their family members in the Horqin left-wing Mongolian tribe.

From the palace of the Khan to the homes of some other Jurchen nobles who married with the left wing of Horqin, a lot of news will pass through the channels of the Horqin women and finally be sent to the hands of Jaisang.

There was a food shortage in Houjin that starved many people to death, and of course this news could not be concealed from Jaisang.

Under such circumstances, the Jurchen Eight Banners of the Later Jin State are simply too busy to take care of themselves, how can they help the Horqin left-wing Mongolian tribes in distress?!

Therefore, when Haskan arrived in Chaganhot with Yang Zhen and Deng Tianhe, and a caravan composed of hundreds of camels, mules and horses that had been coming from Zhangjiakou, Zaisan quickly made a choice.

No matter how the other three banners of Horqin Mongolia choose in the future, and whether they really want to change their banners in the future, and follow the army of the Ming Dynasty to launch an attack on the Dajin Kingdom in the east, the first thing to do now is to get the benefits of sending them to the door first.

This benefit is the caravan from the Ming Dynasty, that is, the trade between the Mongolian tribes of the Horqin Left Banner and the Ming Dynasty.

The Horqin left-wing Mongol tribes, like almost all other Mongol tribes, needed iron pots to stew meat, iron kettles to boil water, iron tools to make scimitars and arrowheads, and salt, tea, and other spices to maintain and improve their lives.

And all this, in the Mongolian steppes of this era, was difficult to obtain through legitimate means.

The caravans that traveled from east to west and north from south to north were the main channels through which they obtained these supplies through peaceful means.

This is because even relatively powerful Mongol tribes like the Horqin left-wing Mongols do not know how to explore and exploit iron ore and smelt steel.

In this regard, the Outer Mongolian tribes of this era were slightly less civilized than the Jurchens who rose in the northeast.

Although the level of iron smelting of the Jurchens in this era was not particularly high, they had mastered a considerable degree of iron smelting technology by absorbing some Han people from Liaodong into the banner.

The vast Mongol tribal areas in Saibei, with the exception of Kuku and Tuncheng, which originally belonged to the Tumut tribe and later belonged to Chahar, were able to smelt iron and steel, and were able to make their own iron, bronze, gold, and silver tools, other small tribes did not have this ability at all.

Therefore, for many Mongolian tribes, iron tools have long been a relatively scarce or even very scarce material in the steppe.

This situation is no exception for the Horqin left-wing Mongol tribes.

Especially after the major battles outside the Ming border in the south, the weapons, arrows, and iron armor of the Mongolian tribesmen on the left wing of Horqin suffered serious losses and needed to be replenished urgently.

But for this request of the Horqin left-wing Mongols, Huang Taiji could not meet it at all.

Because of the small scale of the domestic iron-smelting industry in Houjin, except for the two iron-smelting sites in the old city of Hetuala and the city of Shenyang, other places either cannot produce pig iron, or are not allowed to mine and smelt iron.

The scale of these two iron yards is not large, and the pig iron or 100 smelted iron produced is now given priority to the Ministry of Industry and the Han Army Banner set up by Huang Taiji, which is used to test and cast siege cannons.

The already small pig iron production is even more stretched after cutting off the external source, and even the Jurchen Eight Banners in their own country can't be satisfied, so how can they support the Horqin tribes?

Even a tribe with such a prominent position as the Horqin Left-wing Mongols could not receive a supply of iron from Huangtaiji.

In contrast, the Kulen Mongols, who were currently separated from the territory of the Horqin Left Banner by only one Taer River basin, received a steady stream of substantial funding from the Ming Dynasty.

It was with the funding of the Ming Dynasty, especially with the funding of the Liaodong Governor's Office, that the Ming Dynasty's canonized foreign vassal Fengyi Marquis, that is, Enkhbayar, the leader of the Kulun Tribe, was able to learn from the example of Kundulun Khan Burhatu of the Karaqin Tribe, and built a Kulun City within a radius of five miles in his own territory, that is, in the area of the later Kulun Town.

This city of Kulun is only five miles in radius, and it is actually not very big, and it looks more like a castle.

It does not have the height and majesty of the mountain city of Ulan Hada, nor the impregnable impregnability surrounded by more than 100 heavy artillery pieces at the head of the city of Yiju, two hundred miles to the south.

However, this small steppe town, built with a lot of cement and concrete and bluestone on the Yiwulu Mountain, gave Enkhbayar and his men great confidence.

The reason why the Mongols on the steppe live in felt tents is not because they like to live in felt tents, in the final analysis, in addition to the convenience of felt tents to build, disassemble and transfer, the most fundamental reason is that they do not have the conditions to build cities and fortresses.

The construction of the city requires a large amount of timber, quarrying, and labor, which is behind the large amount of wealth expenditure.

The average steppe tribe can't support it at all.

And once they have such conditions, they will of course prefer to live in a castle with strong walls and strong houses, especially in the era of wars and chaos on the steppe.

Because in this way, you can really ensure the safety of your family and property, and you can not be afraid of the enemy cavalry raids that often occur on the grassland.

After Fengyi Hou Enkhbayar returned to the Ming Dynasty, the best gift he brought to the Mongols of the Kulen tribe was such a small but safe steppe castle.

This castle gave him a strategic advantage in the steppe, which could be attacked and defended, and it was enough for the Enkhbayar brothers to pluck up the courage to lead their men to compete with the Korqin people, who were far more powerful than them in the past.

The Mongols of the Kulen tribe originally belonged to the Chahar Mongols, and they were regarded as an Otok of the Chahar Mongols under the command of Lin Dan Khan.

Kulun, in Mongolian, means courtyard, courtyard, which means that there is a courtyard of a lama temple in this place.

In that year, when Lin Dan Khan led his troops to evacuate the steppes of Eastern Mongolia in a hurry, the Chahar Otok, who was stationed in the area of the lama temple, thought that the future of migrating westward was slim and was unwilling to leave the pastures and homes here, so they did not follow the westward migration.

At that time, they chose to surrender to the Horqin people, called themselves the Kulen Mongols, and became a vassal tribe of the Horqin left-wing Mongols.

However, the Chahars are the Chahars, and they are never of the same mind as the Korqin people.

Especially because the Horqin people were the first to defect to the Jurchens and betray the Mongols, the Mongols from the Chahar tribe were generally full of hostility towards the Horqin people.

Therefore, as soon as they had the opportunity, they immediately broke away from the control of the Horqin people and sided with the side of the Ming Dynasty.

Now, two or three years have passed, and the Kulun tribe has gradually grown and grown after absorbing the nearby Mongols who originally belonged to Naiman, Ao Han and other tribes.

Although there is still a big gap between them and the Karaqin tribes or the Horqin tribes, on the strategic defense line of the Xilamulun River and the Xiliao River, the Kulen Mongols have become two important forces of the Ming Dynasty to prevent the Horqin tribes from moving south, together with the Karaqin Mongols.

In the past two or three years, Zhaisang, the leader of the left-wing Mongolian tribes in Horqin, has witnessed the rapid development and growth of the Kulen tribe, which makes him both envious and jealous, and at the same time feels a fear that time is not waiting.
