With the death of Lin Dan Khan due to smallpox in the grass beach of Qinghai, the light of the golden family was completely annihilated in the long river of history, and the Chahar department, which had a brief period of glory, also fell apart.

As early as the seventh year of the Apocalypse, the leaders of the Naiman and Ao Han tribes in the four left wings of the eight Chahar tribes were at odds with Lin Dan Khan, and turned to Houjin, and the leader of the Uzhumuqin tribe, Daojir, also led his subordinates to migrate to the area of the Krulun River to settle down and have close contacts with the Houjin.

At the same time, there are also sharp contradictions between the four divisions of the left wing and the four divisions of the right wing, in the fourth year of Chongzhen, when the left-wing Alakzhuo Department went out to fight with Lin Dan Khan, it was attacked by a team of 300 sentinels on the right wing, and thousands of old and young were killed.

In the seventh year of Chongzhen, the Keshiket Department also surrendered to Houjin under the leadership of Shalalata, a descendant of Genghis Khan, so far, the left wing of the Chahar Eight Divisions was completely out of the control of Lin Dan Khan, and the right wing of the four divisions were also declining.

During the escape to Qinghai, the two wings of the general officer Tashhai, Huluke Zhaisang led more than 2,000 households to surrender Houjin, Chongzhen seven years in June, Badasisse and other five leaders with more than 1,000 households surrendered, after which the Chahar Department faced the crisis of food shortage in Qinghai, even to the point of killing people and easy to eat, relying on frequent invasion of the Ming border looting to barely survive.

As soon as Lin Dan Khan died, Dou Tumen Fujin, one of his eight wives, took the initiative to surrender to Houjin with the Huluduo tribe under his control, and soon remarried Huang Taiji.

Lin Dan Khan's other wife, Uyunna Fujin, took Alakyut Huluduo away from Mobei, but was attacked by a tribe in Mobei and his whereabouts were unknown, and Alakyut Wanhu Huluduo also perished.

The remaining six Fujin led their respective tribes of Huluduo, either continuing to live in exile in Qinghai or returning to the Hetao region in the cold winter.

Among these six women, some want to escape to the north of the desert and take refuge in the three great khans of Transkhalkha, some want to follow the general trend and surrender to Houjin, and some still hold the hope of restoring the glory of the golden family and want to make a comeback in the Hetao area.

At the same time, the two brothers, Dolgon and Azig, were leading 5,000 Houjin elites across Guihua City to the Houtao region to search for the whereabouts of Ezhe and Lin Dan Khan's remaining Fujin.

Leading the way for the Dolgon brothers were 7,000 Mongol cavalry from the Ordos Division, Naiman, Ao Han and other Chahar Tribes, with a total strength of 12,000.

At the same time, Huang Taiji also ordered Korqin, Tumut, Nekhalkha and other departments to gather 6,000 cavalry to be stationed in the area of Guihua City, in case Qinchuan suddenly went north to cut off Dolgon's back road.

……

In late February of the eighth year of Chongzhen, Emperor Guan's army, which had been dormant for a winter, suddenly had a large mobilization.

A large amount of grain, grass, armaments and other materials were gathered from all over the country, shoveled snow through the newly built official road to the north, and were transported to Tumaochuan Fort and Shiwankou Fort in Qingshui River respectively, and the accompanying Guan Emperor army also continued to merge into these two military forts.

As early as before the snowfall last year, Zhao Wu scattered the 200 nights and sharp whistles outside the Saiwai, and these sentinels trained by him pretended to be business travelers, herdsmen, horse bandits, rangers, etc., and haunted Tumut River, Ordos, Houhetao, and even Trans-Khalkha and other places, spying on the military situation and keeping a close eye on the movements of the various parts of Outer Mongolia.

Zhao Wu even went out in person, and just after the New Year, he took a batch of handcuffs and pretended to be horse bandits and roared north.

Qin Chuan knew that Ezhe had a jade seal and a golden Buddha in his hand, and Huang Taiji wanted those two things.

Especially the former, which is the jade seal of the Northern Yuan Khanate, has great authority over the Mongolian tribes, and it is of great significance to Huang Taiji and even the entire Houjin.

For Qin Chuan, this thing is also of great significance, and if he gets it, he can make the situation in Southern Mongolia more chaotic, make it difficult for Huang Taiji to unify the southern tribes, and prevent Huang Taiji from forming an alliance with the northern tribes.

Only by chaos can he stand firm.

Qin Chuan also knew that Zhu Youzhen would definitely take advantage of the hot fight between him and Huang Taiji to stab him in the back.

According to the information collected by Lao Huang's intelligence department, the Xuanda border army is increasing troops in Shuozhou one after another, and there are also several Ming troops gathering in the area of Zhending Mansion in the east and Weihui Mansion in the south.

Even, there is a new Ming army in Fenzhou, about 5,000 people, according to intelligence, this Ming army should be recruited by the gentry in Zhuzhou County in southern Shanxi, the new recruit is not long ago, and now it is being trained in Fenzhou, and the leading military commander is Jiang Xuan, the deputy chief soldier of Shanxi.

Among the complicated pieces of information, there was one piece of information that caught Qin Chuan's attention: not long ago, a strange fleet of ships appeared in the canal, only seven ships, without any flags, and the goods on them were also covered with cowhides, the number was not much, but the draft was very deep, and the ships were heavily guarded, the guards were unknown, and there were a large number of equally unidentified people accompanying them on the way north along the canal.

According to the intelligence section's whistle description, most of them were dark-skinned, with thick calluses on their hands and wide feet, which did not look like people who could not afford to buy shoes, but many of them were barefoot on cold days.

Along the Grand Canal, there were many officers and soldiers who blocked the road and demanded money, but when all the officers and soldiers blocking the river encountered this fleet, they would get out of the way in a gloomy manner, and no one dared to stop them.

At first, the flotilla was not too conspicuous until they turned into the Yellow River and broke through the thin ice on the river and continued northward, attracting the attention of the intelligence sentry.

This piece of information also attracted Qin Chuan's attention.

Obviously, the fact that the fleet was carrying something very important to some people, and that no officer or soldier dared to stop it along the way, indicating that the fleet was not small.

The draft indicates that the cargo is heavy, and it is very important to carry heavy cargo...... It's either gold or silver.

But along the Yellow River, along the way up the boundary wars are frequent, the rogues are repeatedly suppressed, and a little further up is the territory of Qinchuan, who will transport a few ships of gold and silver to this dangerous territory in this period of war and chaos?

The gentry in the north are busy transporting gold and silver to the south to hide, who will swim against the current?

Fool not to be?

Isn't it gold and silver?

What would that be?

Qin Chuan couldn't figure it out, and he couldn't find a reason for finding a group of subordinates to discuss for a long time.

He only knows that when things go wrong, there must be demons.

Therefore, he strengthened the defense in the south and west, and specially transferred more cannons to Gujiaobao and Yongning Prefecture, including the fortress cannon newly built by Chen Zhan.

It's not a lot of it, but it's powerful, and the downside is that it's too bulky and only suitable for defense.

After the defense arrangements in various places were in place, Qin Chuan led two thousand red-clothed attendants who had just expanded the army to fight north.

On this trip, he was going to rob a few widows to come back.

Prior to this, the generals such as Bobcat, Hu Dawei, Cao Bianjiao, Batu, and Li Dingguo had already divided their troops and led their respective generals to go north to find those widows.
