"Your Majesty, this is Ji County. There is a mountain here called Lingqi Mountain, and there is a cave in the mountain called Jizhou Cave.
The cave covers an area of one hundred acres. It is warm in winter and cool in summer, so it is very comfortable for five to six thousand people to be stationed there.
The important thing is that this place is the only place to go from Zunhua to Beijing. It is more than two hundred miles away from Beijing in the west and less than a hundred miles away from Zunhua in the east.
If something happens to Zunhua, we can make a quick march from here and arrive in one day. "
After Sun Zushou finished speaking, he pointed to another place: "This place is Qian'an City. There is a mountain here called Jiangjunmao Mountain, and there is also a cave on the mountain called Hongyu Cave.
The overall distribution of the caves is in the shape of beads. The larger ones are fifteen or six feet deep, four to five feet wide, and three to four feet high. The smaller ones are seven to eight feet deep, three to four feet wide, and two to three feet high.
The holes are connected to each other, and the holes are connected to each other. It is not a big problem to station more than 10,000 people.
It is only more than a hundred miles away from Ji Town and is the only place to pass from Zunhua to Shanhaiguan. "
"The third place is located in Xinglong County. There is also a cave here. The cave is extremely empty and can accommodate more than 10,000 people."
"Your Majesty, Cao Min and Commander Cao have personally led people to inspect these three places, and also asked Jin Yiwei to inspect them locally. There is absolutely no problem.
I believe that these three places are excellent hiding places. As long as we do a good job and seal the cave entrances,
There is no problem in creating some legends about bandits, horses and thieves who took over the mountain as kings, jackals, tigers, leopards and giant pythons hurting people, mountain collapse, and the passage of Yin soldiers. It can be kept secret for two or three months. "
Chongzhen looked at the map and said nothing, but he was making rapid calculations in his heart.
If Jiannu retraced the route of the Jisi Revolution in the second year of Chongzhen, he would divide the east and west routes and attack the Great Wall Passes Longjing Pass and Da'ankou respectively, and then break through the west wind pass.
Then from Xifengkou to Hanerzhuang, go straight to Zunhua, and then break through the Santun Camp.
They transferred their troops to attack Jizhou and besieged the city of Beijing. They finally defeated the towns of Qian'an, Zunhua and Luanzhou and returned north.
Sun Zushou mentioned three places, Xinglong, Jizhou and Qian'an. Xinglong is more than 130 miles northwest of Zunhua.
Jizhou is less than a hundred miles due west of Zunhua, while Qian'an is more than 130 miles away from Zunhua and more than a hundred miles away from Santun Camp.
It just happened to surround Zunhua and Santun camps in the middle, allowing them to attack and block the enemy.
The most important thing is that Xinglong is less than a hundred miles away from Da'ankou and Longjing Pass where Jiannu entered the pass, while Qian'an is only more than a hundred miles away from Xifengkou.
The goal of the Baigan soldiers and the Tengxiang left guard was to block the retreat route of the Jiannu entering the Pass. The main force that really surrounded and killed the Jiannu was the Nine Guards of the Forbidden Army and the troops from Jizhen.
Once the Jiannu attacked Zunhua, the two troops would be able to block the Great Wall pass. With the natural danger, the Jiannu could only retreat eastward, and they would encounter reinforcements rushing from Shanhaiguan.
At that time, the troops from Shanhaiguan, Beijing City, and surrounding garrison stations can rush to support Zunhua, and the purpose of the siege will be achieved.
"Cao Aiqing, your Tengxiang left guard immediately moves to Hongyu Cave!"
"Qin Aiqing, you white-pole soldiers immediately move the division to Xinglong Cave!"
"Sun Aiqing, during this period of time, you are responsible for the central coordination and the supply of food and grass. If you need any support, please contact Jin Yiwei directly."
"My dear friends, this matter is the highest secret of the imperial court. No one can reveal it except the four of you. The speed of changing the location can be slow, but the news must not be leaked."
"I understand!"
The four people immediately stood up to respond, saluted and left.
After the four people left, Chongzhen let out a long sigh.
As expected, marching and fighting had to be done by professionals. He had thought it was simpler before.
If it weren't for Sun Zushou's rescue, even if the plan could be implemented smoothly, he would have been huddled in a cave for two or three months without training.
The combat power of the white pole soldiers and Teng Xiang's left guard will also be greatly weakened, and their blocking effect will be much worse.
Judging from the current situation, the Guanning Defense Line built by Sun Chengzong is extremely correct. With the establishment of the Guanning Defense Line, Jiannu had only three ways to enter the Ming Dynasty.
Either directly attack Ningyuan City, push all the way to Shanhaiguan, and then break through and enter.
The second is from the water route, but Jiannu does not have a navy, and even if it did, it would not be able to withstand the pincer attack of Pidao and Denglai navy.
The third is to take a detour to Mongolia, but most of the Mongolian tribes are resistant to and look down upon the slaves.
Therefore, Jiannu could only defeat the Mongolian tribes and form an alliance, so that he could have a chance to attack the Ming Dynasty in a detour.
Without the Guanning Defense Line, Jiannu would have too many opportunities and places for sneak attacks.
After rearranging the things he had been worrying about, Chongzhen could finally live a stable life for a few days.
But just a few days after the peaceful days, on the third day of June, before Chongzhen returned to Dongnuang Pavilion after leaving court, Li Ruolian hurried over with a sealed box.
"Your Majesty, Xuanfu Town is full of Gui General Soldier's 600-mile rush!"
"Xuanfu?"
Chongzhen was a little confused: "Tear it apart!"
As Chongzhen talked, he walked towards Dongnuang Pavilion, secretly guessing in his heart, could it be that Jiannu wanted to attack from the Xuanfu defense line?
The possibility is not high. If Jiannu dares to attack Xuanfu, then Lin Danhan will definitely not let go of this opportunity for a flanking attack.
When they arrived at Dongnuan Pavilion, Li Ruolian presented the secret letter to Chongzhen.
"Man Gui, the commander-in-chief of Xuan Mansion, respectfully invites His Majesty to pay homage to His Majesty. On the second day of the sixth lunar month in the first year of Chongzhen,
Xuanfu scouts discovered that the Jiannu Allied Forces, which were more than 500 miles away from Xuanfu, began to accelerate their march to the west. The target was suspected to be Tumut Guihua City.
At present, it is known that there are more than 70,000 people in the Jiannu coalition army, including more than 30,000 people in the Jiannu headquarters.
The remaining Aohan, Naiman, Khalkha, Horqin, Zharut tribe, and Kalaqin each contributed from 5,000 to 10,000.
In addition, the six Hongyi cannons sent by the Firearms Research Institute have been fully installed and test-fired, and I have sent scouts to pay close attention to the movements of the slaves. "
After reading the urgent information from Xuanfu, Chongzhen made a judgment in his mind that Lin Danhan and Tumut must have started to collide, or even finished the fight.
Next, let’s look at the transaction between Hei Yunlong and Lin Dan Khan, and the collision between Lin Dan Khan and Jiannu.
Xuanfu's Hongyi cannon has been installed, which makes him feel more confident.
A few days ago, he went to the Firearms Research Institute, and Xu Guangqi reported that he could now produce three to four Hongyi cannons every month.
From the establishment of the Firearms Research Institute to the present, a total of twenty aircraft have been produced.
Eight of them were sent to Liaodong, and he intercepted the twelve to be sent, six each from Xuanfu and Datong.
There are Hongyi cannons in the two towns, plus the horse pit that extends for two miles and the Juma stake in the city.
There are also troops transferred from Zhenbao, Changping, and Jingying, so the defense should be no problem.
"Your Majesty, Datong Town Commander Hei Yunlong Liubaili is urgent!"
Another voice interrupted Chongzhen's contemplation, and Chongzhen, who woke up, immediately said: "Tear it apart!"
Then he said: "My dear companion, Sun Chengzong and Yuan Keri have come to see me in Dongnuan Pavilion!"
There was an emergency report from Xuanfu in the first place, and an emergency report from Datong Town in the second. It can basically be concluded that Tumut and Chahar Lindan Khan started to collide.
While talking, Li Ruolian opened the lacquer box, took out the secret letter and presented it to Chongzhen.
