Of course, the Ming army built the fortress not to store food, but to limit the mobility of the Manchu and Mongolian cavalry, trapping them in the three steppes, so that they could not carry out sneak attacks everywhere. Besides, the Ming army didn't need to build a special place to store grain, because the places they passed through were full of fortresses, and there was no possibility of the grain route being intercepted at all!

100,000 or even 300,000 people to build a fort is quite amazing, plus the Ministry of Industry prepared abundant military supplies, not only the cement and steel bars are ready, but even the wooden plywood used to pour reinforced concrete is ready, so basically the cement is dry and a fort is repaired, and the construction of a fort is five or six days at most!

Lu Xiangsheng's east road is particularly exaggerated, he is not afraid of the Qing army to sneak attack, so he divided his army into two roads, he led the Tianxiong army 50,000 Wuwei army to escort 150,000 prisoners for one way, Cao Bianjiao and Li Mingfu led the first regiment of the border guard army 50,000 Wuwei army and 150,000 prisoners for the other way, the two roads started at the same time at the adjacent entrance, take care of each other, five or six days he can build two!

The Manchu Qing Dynasty had not yet learned telegraph communication, and their communication was still basically transmitted by roaring, or by fast horses, so when Huang Taiji noticed that something was wrong, the Ming army on the south and north roads had already begun to build the third fortress, and Lu Xiangsheng on the east road had already begun to build the fifth and sixth fortresses!

Huang Taiji marked the location of the fortress on the map, and couldn't help but break out in a cold sweat, the exits of the three grasslands and the interconnected passages were almost blocked by the Ming army!

"Sun Chengzong, you old king!" Huang Taiji was so angry that he vomited blood, he really vomited blood, as analyzed before, he should have a respiratory disease, and he vomited blood at every turn.

Sun Chengzong is simply his nemesis, let him be full of wisdom, this old Wang Ba only uses one trick, repair the fortress, repair the fortress, or repair the fortress, even if he has a thousand tricks, people just don't play with you, they only know how to build the fortress vigorously, what can you do with him? Is it necessary to change direction and develop hoplites? Let a nomadic tribe develop infantry and not cavalry, unless the head is kicked by a donkey!

After vomiting blood, he hurriedly analyzed the current situation, time waits for no one, according to the speed of the Ming army building fortresses, in more than ten days, all the exits and connecting passages of the three grasslands will be blocked, and at that time he will lose contact with the Horqin grassland and Hailar grassland.

After analyzing for a while, he issued an order, ordering the Qing troops scattered in the Horqin grassland and Hailar grassland to immediately ride all the war horses they could ride and rush back to the Chahar grassland from the few remaining passages, as for what to do if the Mongolian tribes on the Horqin grassland and Hailar grassland have no war horses, he can't take care of it, and if he hesitates, the passage will be blocked, and the 100,000 Qing troops stationed in the two grasslands will be given to the Ming army in vain!

He now transferred all the 100,000 Qing troops back, and there is still a chance to fight, because the little emperor still doesn't know the secret that he has a large number of muskets and artillery, if he is surprised, defeat the Ming Dynasty's East Road army in one fell swoop, and capture the little emperor, he can repeat the great victory of the civil fort of the Mongolian Tile Spur Department, and let the Ming Dynasty be in chaos!

In Huang Taiji's view, it is not impossible to defeat the army of the Ming East Road, because according to the secret agent, the total number of the East Road army is 300,000, and the little emperor is now building fortresses all the way, and each fortress must leave at least 10,000 or 20,000 people to garrison, so that the final force that can be used to attack the Chahar grassland is only 250,000 at most, and the Qing army will have 200,000 after all the troops are assembled, and the total number of Mongolian troops in the Chahar grassland is 300,000, and 300,000 to 250,000 weapons is a bit disadvantaged. But with an absolute advantage in the number of cavalry, the chances of winning should be large.

As for the problem of intercepting grain and grass, he doesn't think about it anymore, people have built so many fortresses, you know which fortress the grain and grass are hidden in, and it is more likely that there are in each fortress, so what's the point of playing down one or two, and, according to the spies, the fortresses of the Ming army are all built on the mountain bags with dangerous terrain, and no one on his side shoots far from the artillery, and the terrain is not conducive to the development of the army, so there is no way to take a fortress in a short time.

Therefore, Huang Taiji gave up the plan to cut off grain and grass, and went all out to reorganize his army for war, preparing to fight with the little emperor in the Chahar grassland!

And what is our Chongzheng Emperor Zhu Cijiong doing? He was sitting in the third fort with a telegram in a daze, Huang Taiji actually withdrew all the Qing troops in the Horqin Grassland and Hailar Grassland to the Chahar Grassland, and also rode away all the war horses, which means that he is ready to give up these two grasslands, because the combat effectiveness of the Mongolian army without war horses is not even as good as the third-class army of the Ming Dynasty!

Zhu Cijiong is also analyzing, but he has detailed information for reference, so the analysis seems to be simpler, Huang Taiji gave up the Horqin Grassland and Hailar Grassland and did not escape, there is only one possibility, that is, he thinks he can defeat his Southern Route army!

If Huang Taiji knew that Zhu Cijiong guessed his thoughts so easily, it was estimated that he would vomit three liters of blood in anger.

Since he guessed Huang Taiji's thoughts, Zhu Cijiong naturally wouldn't be stupid enough to lead such a few people to a decisive battle with Huang Taiji, and after thinking about it for a while, he finally sent a telegram to Lu Xiangsheng and Sun Chengzong:

ordered Lu Xiangsheng, the commander of the Eastern Route Army, to hand over the 50,000 elite cavalry of the Tianxiong Army to Cao Bianjiao, rush back to Haizhou, take a train to Beidaying, and then secretly rush to the southwest corner of the Chahar grassland to assemble and stand by;

ordered Sun Chuanting, the commander of the Northern Route Army, to hand over the 50,000 elite cavalry of the Guanning Army to Cao Wenzhao, rush back to Guanning, take a train to Beidaying, and then secretly rush to the southeast corner of the Chahar grassland to assemble and stand by;

Sun Yuanhua, the secretary of the military department, mobilized thirty trains to Haizhou City and Guanning City respectively, preparing to transport the cavalry of the Tianxiong Army and the Guanning Army.

Of course, he can also transfer more troops from the East Road Army and the North Road Army to the South Road to support, but, after all, the Horqin Grassland and Hailar Grassland each have 100,000 Mongolian troops, if the East Road Army and the North Road Army are only 100,000 left, or 100,000 are not left, it will be more difficult to attack the two grasslands, besides, what if the movement is too big and scare Huang Taiji away, 50,000 each is already the limit, and if you adjust more, Huang Taiji will definitely notice, in case he runs away again, it will be troublesome again.

After sending the telegram, he continued to lead the army of the South Road to the next exit of the Chahar grassland, there are still two fortresses to be repaired, first block all the exits for him, after repairing the two fortresses Cao Bianjiao and Cao Wenzhao led by the elite cavalry should also be in place, when the time comes, two dark and one bright, go straight to the location of Huang Taiji's Khan Court, see what tricks he can play!

By November 8, the construction of the last two fortresses was finally completed, and by this time, the elite cavalry led by Cao Bianjiao and Cao Wenzhao had also been in place, and their communication troops had already pulled the telegraph lines over.

Zhu Cijiong no longer hesitated, and directly led the First Army of the Praetorian Guard, the Qin Army and the 50,000 Dingliao Army to set off, and went straight to the location of the Huang Taiji Khan's Court.
