One hundred and twenty miles north of Laoniuwan Fort, on the bank of the Qingshui River, Shiwankou.

"Second master, why did you say that our general came to build a military fort in this place where birds don't?"

A shirtless sturdy man asked Huang Erdan, who was patrolling around with his hands behind his back and happened to pass by.

Huang Erdan stopped and waved his hand mysteriously: "General Qin said that no one should leak military aircraft to the outside world. ”

Another thin man next to him, who was also shirtless, took over with a smile: "Second master, who doesn't know that the general is going north to kill the Tartars and grab the territory, don't sell the guanzi." ”

Huang Erdan was anxious: "How can this be called robbery?" General Qin was recovering the lost territory of the Ming Dynasty. ”

"Yes, yes, what the second master said is, this is not called robbery, it is called reconquest, the villain's mouth is ......"

"Second master, I heard that the Tartars in Hetao have been driven away by Jiannu, and there are not many enemies in that area at all, so why don't you just lead troops to kill them?"

"You know the fart, General Qin is called a battalion step by step, and if he fights down, he has to build a city to defend it, and prevent Jiannu from coming over, besides, there are large tracts of wasteland on both sides of the Qingshui River that can be reclaimed, and there are many ravines around it that are suitable for farming, and if you build a military fort here, you can move people here to farm."

"What the second master said is that this vision is different from ours."

"By the way, second master, can you tell me how you found out that Lou Nu had a slave, and how you ran to report to the general?"

Hearing this question, the surrounding men looked over one after another, looking at Huang Erdan with curiosity and hope.

Everyone's eyes made Huang Erdan very useful, pretending to hesitate for a moment, then slowly sat on a big stone, and said: "Okay, it's nothing to tell you, there was nothing to do in the cold back then, so I thought about going up the mountain to make up for my mother-in-law and baby, but I didn't expect ......"

As soon as the topic opened, Huang Erdan was out of control, and talked vividly about when he went up the mountain to dig squirrels, he accidentally found Jiannu, and risked his life to run to inform General Qin.

The migrant workers who were working around all put down what they were doing, gathered around, and listened attentively.

Hearing that General Qin personally led a hundred red-clothed attendants to break off in order to protect hundreds of craftsmen and people, and was still fighting bloodily with more than a dozen knives and arrows under the siege of two hundred Jiannu elites, the surrounding migrant workers clenched their fists one after another.

Not far away, several big foremen of the engineering team were gathering together, discussing construction problems in front of a pile of drawings.

On a newly built road, countless mules and horse-drawn carts are in an endless stream, transporting building materials such as steel bars, cement, sand and gravel, formwork, and top wood to the construction site.

These building materials were first transported from Lou Fu to Yatou Pass, and then from the side wall of Lao Niuwan Fort to the Qingshui River.

The whole journey of more than 400 miles, Jiannu began to transport before entering the customs, until now, there are still transport teams starting from Lou Fu every day, and there are mules and horses every day in the states and counties along the way to supplement forage and replace mules and horses.

The construction of a large number of military forts in the Hetao area was a huge and protracted project.

Nowadays, there are two military forts that are started at the same time, one is at the mouth of Shiwan, and the other is at the confluence of Qingshui River and Tumao River, which is the place where Qinchuan attacked and killed Laosa, built on the south bank of the Qingshui River, close to the mountains and rivers, easy to defend and difficult to attack.

The distance between these two military forts is sixty miles, forming horns with each other, echoing back and forth, which can not only rely on the Qingshui River to block the road to the south, but also control the Qingshui River, the only water source within a radius of tens of miles, so that the enemy from the east cannot advance west along the water source.

In addition to the defensive position, these two military forts were also the pedals for Qinchuan to go north.

Because, the Qingshui River is only two hundred and fifty miles away from the city of naturalization.

For the two military forts of Qingshuihe, Qinchuan mobilized 2,000 construction teams and 8,000 people, a total of 10,000 laborers, and more than 2,000 mule, horse-drawn carts and chicken carts.

At the same time, Yan Sanqi is leading a group of craftsmen to build a new cement factory near Bitouguan, and after it is completed, there will be no need to transport cement from Lou Fu all the way.

As long as there is a river, there will be available sand and gravel, just dig the sand on the spot or nearby.

In addition, Qinchuan also sent people to look for iron ore near the border, preparing to open iron ore outside, and build steel factories to supply the construction of military forts, and also build pot factories to prepare for the mass production of iron pots, which were sold to Khalkha, Yarkand, Rakshasa and even the Middle East and Europe.

You can consider exchanging the iron pot for some Yanmar to come back and play.

On several mountain beams not far from the east of Shiwankou, there are two flags in turn, one pole is written with the word "Luo", Luo Daniu's first camp is stationed there, and the other pole is written with the word "Ren", which is Ren Liang's Longwu camp.

Near the construction site of the Tumao Chuankou, there are also the Tiger Guard Battalion of the Lynx and the Tiger and Leopard Battalion of Liao Sangun, with a total of 12,000 troops at the head of the four battalions, commanded by Luo Daniu, to guard the construction of the two military forts.

Qin Chuan began to consciously cultivate the generals under him, he needed a few generals who could lead the troops alone, and when the territory expanded, he had to divide several border towns like the Ming Dynasty, and each general would manage the defense, and after the overall strength was large enough, he would also formulate multiple offensive routes and hand them over to the generals under his command.

The key training is naturally Luo Daniu, Li Dingliang, and Liu Youzhu, these three are all old brothers of Jiuji Mountain, loyal, and have fought for many years, and can be convincing in terms of experience, qualifications, and ability.

followed by Luo Ba, Lynx, Li Dingguo, and Cao Bianjiao, among these people, the first two are also old brothers of Jiujishan, and they have abilities and qualifications.

In the latter two, Li Dingguo has the potential to become a generation of good generals, although Cao Bianjiao is not as famous as Li Dingguo in real history, but he leads the troops to charge into battle very well, with Cao Wenzhao when he usually leads the cavalry all the way to the storm, and during the battle of Songjin, he also rushed to the front of the Huang Taiji sweat tent, which is the best choice for the vanguard general.

There are also Zhao Wu, Liao Sangun, Ren Liang, Feng Yilong, Liu Wenxiu, Ai Nengqi, Feng Shuangli, Zhao Sandao, Hu Hai, Zheng Qiting, Qin Boyang, Zhao Lishan, etc., these generals are the mainstay of the future, and they are also among the ones that can be cultivated.

Now, Bobcat, Ren Liang, Liao Sangun, Cao Bianjiao, Li Dingguo, Feng Shuangli, Zhao Sandao, Zheng Qiting, Qin Boyang and other generals are gathering in Luo Daniu's camp, discussing something in front of a map and a sand table.

The map depicts the terrain from the side wall to the Naturalization City, and is marked with a number of black dots and two red dots, the black dots are the settlements of the various tribes of the Tumut tribe, several of which are marked with triangular flags, which are the big tents of the leaders of each tribe, and the two red dots are the locations of the two military forts that the Guan Emperor Army is preparing to build.

This map, drawn by Zhao Wu under the description of Batu and the rest of the Chahar people, and corrected by field surveys, is very accurate, and it is so detailed that most of the mountains and ravines are drawn.

The sand table is based on a map, outlining all the important roads, mountains, and ravines, so that the generals can more intuitively understand the environment of the battlefield.

Since the arrival of the Guan Emperor's army at the Qingshui River, several small tribes of the Tumut tribe who were grazing cattle nearby have fled when they heard the news, according to the news from the area around the Naturalization City, the various tribes of the Tumut tribe are gathering in the Naturalization City, but there are not many soldiers and horses, and the adult males detected at present are only about six or seven thousand.

Obviously, Emperor Guan's army suddenly sent troops to the Qingshui River, making the Tumut troops feel like a great enemy.

With their little strength, they didn't dare to take the initiative to attack, and the Tumut Department also suffered a big loss from the Guan Emperor's army in Xuanda, knowing that this suddenly rising army was very difficult to mess with.

Therefore, they are likely to withdraw first, and report to their Jianzhou master as soon as possible, and wait for the master's army to arrive before making a decision.

The task given to Luo Daniu by Qin Chuan was not only to protect the fort, but also to attack the Tumut Division, defeat the opponent's main force, drive away some of them, and surrender some of them.

After discussing with the generals for a long time, Luo Daniu planted four flags on the sand table, and then issued orders one by one.

Not long after, everyone left, and soon the camp was filled with shouts and whistles.
