At the construction site of the Hongluo Mountain defense line, at noon, all the people began to rest in three shifts, and the resting people gathered in the open space behind them, and they were queuing up to receive lunch.

Flatbread larger than a sea bowl was handed over, and a large spoonful of piping hot broth was poured out, and the bowl was immediately full. Although there is only some minced meat in the broth, and it is also made of cured meat, it is already a first-class delicacy for these people, and even the family can't drink such broth during the New Year.

Under the attraction of this delicacy, some of the people in the crowd began to cut in line, and even directly snatched the people who had finished their lunch in front, and the soldiers of the new army in Qinglai Town, who maintained order around them, saw it, and rushed up directly to arrest those unruly people, and beat them violently in front of all the people, so that they cried and cried for mercy.

The surrounding people all applauded when they saw it, and their hearts were completely down-to-earth, and it was the first time that such a reasonable official and army had seen it.

Chen Xun had just sent Liu Yan away, and at this time the construction matter was on the right track, Liu Yan naturally would not keep an eye on it here, and only when the main project was completed, Liu Yan would come back to inspect.

At this time, Chen Xun saw that the soldiers who maintained order began to shout, and asked the people who had almost finished eating in the previous class to take over the work.

The soldiers who served shouted loudly, brandished their hoes and pickaxes, and kept digging trenches and digging earth. There are also people who carry dustpans and baskets, who are responsible for carrying the soil, and there are people who build walls, who use splints to throw soil into the board, and try their best to ram them with pestles, and the sound of the bag is continuous, and the scene is in full swing.

Due to the large number of people on Hongluo Mountain, the seemingly huge project was basically completed in only two days, and the rest of the matter was the specific deployment of the soldiers of the former battalion.

Chen Xun immediately paid all the people, and then ordered the soldiers to send all the people down the mountain and hand them over to the staff of the Governor's Palace for arrangement.

The good days ended so quickly, which made all the people very low, and almost everyone thought in their hearts that it would be good if the project here lasted a year and a half, but this can only be a good wish.

On the same day, Chen Xun took Wei Han, Guo Mingxu, and Shen Donglai to inspect various places and began to deploy troops in the defense line, and more than 12,000 soldiers in the front battalion, as well as a large number of firearms such as Xiaoforang machine guns, Baizi guns, and Huzun cannons were also deployed one by one.

At dusk that day, Liu Yan received the news and rushed to the Hongluo Mountain defense line, and after inspecting it accompanied by Chen Xun, he was very satisfied. After a lot of manpower construction, coupled with the terrain advantage of Hongluo Mountain, this is destined to be a much more terrifying place than the Julu defense line and the defense line under the city of Jinan, if the Qing army dares to attack the mountain, it will become the defeat of the Qing army!

Early in the morning of the second day, Hong Chengchou, the governor of Jiliao, who got the news, also led a huge number of generals to the Hongluo Mountain defense line to inspect.

In just two or three days, Hongluo Mountain has completely changed its appearance, and the trees and weeds of the whole mountain have been cleared, making the mountain up and down, and the line of sight is extremely open.

As they walked up from the foot of the mountain, the trail seemed to become gentler and the road was easier to walk, and everyone did not understand what was going on at first. Isn't this convenient for the enemy to attack?

Hong Chengchou didn't understand either, so he asked, and Liu Yan explained that this was to let the Tartars concentrate their forces as much as possible in this mountainous area, so that the artillery on the mountain could better concentrate on killing.

A chill swelled in everyone's hearts, this Liu Yan was too ruthless, he could think of such an idea?

Then everyone was about to reach the mountainside, and the slope was not easy to walk, and there were deep trench traps everywhere, and there were sharp wooden thorns under the trenches, which made people feel cold, and if they fell, they would definitely become meat skewers.

Moreover, these trench traps are quite cleverly disguised, with a gentle low wall or mound in front of them, so that the view is not clear from behind, but the consequences of jumping over are ......

And what's even more poisonous is that these trench traps are all serial sets, jumping over one and another, sometimes seven or eight in a row, and if you don't fall to death, you will die of exhaustion. 33

These trench traps, which are still irregular, zigzag between the various slopes, make the slopes extremely difficult to navigate. If the attack is covered by shield vehicles, it will not be possible to advance smoothly in any direction, and if you do not dig up the countless low walls in front of you and fill in the countless trenches, you will not want to force the front. And if the Qing army really did this, I don't know how many people would die!

Looking at the cleverly camouflaged, but deeply frightening trench, as well as the sharp wooden thorns below, except for Yang Guozhu, he was arrogant and arrogant Bai Guangen, the chief soldier of Jizhen Town, and they all subconsciously stayed away from Liu Yan, this guy is too vicious, who are the people under his command? I also came up with this kind of ghost idea, not a human being.

Wu Sangui looked at Liu Yan with deep meaning, asking himself this kind of defense, even if he wanted to break his head, he couldn't design it.

Then they saw a number of passable passages, about ten passages, each about twenty paces wide, which went down the hill to the mountainside, without any obstacles, which facilitated the enemy's attack, and made them crowd into a crowd, making them an excellent target for the bird-bearers in the rear.

And the soldiers of the new army in Qinglai Town can also rush out of these passages when they counterattack, which has a great effect.

At this time, everyone's hearts were already shocked, and these arrangements were only the first line of defense. When they reached the front of the first low wall, they saw that the front was suddenly much steeper, and it could be seen that the slope of the mountain had been clearly transformed, and it was all cut into a slope shape along the mountain from north to east and from south to west.

On the top of the slope, a low wall stood tall, about the height of each person's chest, but it was very thick, and the soldiers behind the low wall could rely on the low wall to shoot at the targets in front of them.

Even the slope has a low wall, the wall is about two zhang high, there is a deep large trench in front of the low wall, and there are two small trenches in front of it. The big trench is one zhang deep, one zhang wide, the small trench is half a zhang deep, half a zhang wide, the trench is placed under the sharp wooden thorns, the front end of the wooden thorns has been roasted with fire, and the sharp and hard are incomparable.

The three trenches are separated by two steps, and on the flat ground between them, there are layers of wolf's tooth and strange stone-like red deer barbs, and the sharp barbs on them have to choose people to eat.

The day before yesterday, Liu Yan said that every three low walls and trenches were a line of defense, and every time the Qing army attacked a low wall, it would have to face three fierce firepower from the upper and lower fires.

At this time, Hong Chengchou, Wu Sangui and others looked at the defense line in front of them, and finally understood what Liu Yan meant.

I saw that there was another sloping wave not far behind the low wall, and there was a wall on the slope. Then there were slopes, and then there were low walls. Three low walls, along the mountain, one higher than the other, towered in front of everyone's eyes.

Looking at the three slopes and low walls, everyone understood what it meant to be three up and down, three-dimensional firepower strikes.

At this time, the former soldiers of the new army in Qinglai Town were stationed in Hongluo Mountain, and seeing that they had been stationed in various parts of the three defense lines, Hong Chengchou and others could already imagine what a tragic situation the attacking Qing army would be when the soldiers of the new army shot from the three low walls at the same time.

At this time, everyone was talking about it, and they admired Liu Yan's defense line very much. Cao Bianjiao, the chief soldier of the Oriental Association, and Wang Tingchen, the chief soldier of the former Tun Guard, were even more excited, and the two of them made a calculation, and then asked Liu Yan for advice, Liu Yan immediately agreed to send someone to Wudaoling to guide the two subordinates to build a defensive line, Cao Bianjiao and Wang Tingchen were overjoyed and thanked Liu Yan again and again.

Hong Chengchou also praised Liu Yan, and even praised Liu Yan as the first person in the army's defense.

Then the people entered the rear through the passage, walked a few steps to the right, entered the second low wall, and then walked more than ten steps to the left, and after entering the third low wall, this is a relatively gentle slope, about dozens of steps wide.

There were already many tents here, and many sacks filled with dirt were piled up around the tents, forming a half-man-high wall to block possible artillery bombardment by the Qing army. It was used as a garrison and resting place for the soldiers of the former battalion, so the fortifications were also indispensable.

Looking at those sacks, Hong Chengchou said: "These are the things that Mr. Liu mentioned that can prevent the shelling of slaves and thieves?" ”

"Exactly."

Immediately, Liu Yan explained it simply, and everyone also remembered it, and they also had to prepare some spare ones after they went back.

The group continued to march, and behind the slope was a low wall of a trench, the same as the previous defensive line. After three successive passages, when they reached the top of the mountain, they saw a fort under construction, built on a rocky protrusion, with a wide view of the surrounding area, from which they could overlook the whole mountain.

Then everyone went to the top of the mountain, the top of Hongluo Mountain is quite wide and long, and there are some ups and downs, which are composed of several small mountain ranges, so it is called Hongluo Mountain. Here, around the front and back of the fire road pier, many soldiers from the former battalion of the new army in Qinglai Town are busy building the walled city.

The walls, gates, and residences of this walled city are basically built with large pieces of solid mountain stones, and the walls are also concave and convex, and towers are still being built at intervals, which is expected to form multiple strikes of crossfire.

However, this project is huge, and it will not be completed in a while, but fortunately, the front defense line is completed, and the city wall in the rear can be calm.

In the main village, there will also be many granaries, Hongluo Mountain is the place where the Ming army is stocked with grain, Hong Chengchou is also very happy to see this, and then ordered the prison army Zhang Ruoqi to transport a few batches of grain and grass over, the defense line here is strong, you can hoard as much food as possible, and you should be foolproof.

Zhang Ruoqi also nodded in agreement, and then commanded everyone around him.

At last they reached the northeastern part of the mountain, where there were also several low ditches that meandered along the river to the northwest side of the mountain. On the northwest side, according to the topography, several stone walls have been built.

When everyone looked at the Hongluo Mountain defense line, whether it was Hong Chengchou, Zhang Ruoqi, or Wu Sangui, Yang Guozhu and other chief military officers, everyone agreed that this place was impregnable. There is a Hongluo Mountain defense line, and the back road of the army is foolproof.

The next day, Hong Chengchou led the main army back to the camp and prepared to march. At the same time, Liu Zhaoji, the chief military officer of Liaodong Town, Dou Chenglie, the general of the meritorious staff of the general patrol, and Zheng Yilin, the deputy general of Xingshan Road, led more than 20,000 defenders in Liaodong, and stationed in Xingshan Fort, Daxing Fort, and Dongqingbao inside and outside the periphery, and together with the soldiers of the front battalion of the new army in Qinglai Town, Hongluo Mountain, to guard the back road for the reinforcement army.

Cao Bianjiao and Wang Tingchen also recruited a large number of people to dig trenches and build walls in Wudaoling, and imitated the actions of Hongluo Mountain according to the topography.

At this time, the Qing army scouts also began to appear in the area of Wudaoling and Hongluo Mountain to investigate, but the front camp of the new army and the two towns were very effective in not collecting at night, and the Qing army scouts were driven away one after another, and the two sides fought very hard.

At the same time, Hong Chengchou, who was in the camp, also received urgent reports from various ministries, learning that the main force of the slaves and thieves was on the north bank of the Daughter River, which was more than ten miles away from Wudaoling, and it seemed that they were also building on a large scale.

On the same day, Hong Chengchou, the governor of Jiliao, Zhang Ruoqi, and Ma Shaoyu, the superintendent of the army, accompanied Liu Yan, the chief military officer of Qinglai Town, Yang Guozhu, the chief military officer of Xuanfu Town, Wang Pu, the chief military officer of Datong Town, Zuo Guangxian, the chief soldier of Shanhaiguan Town, Ma Ke, the chief soldier of Shanhaiguan Town, Bai Guangen, the chief soldier of Jizhen Town, and Tang Tong, the chief military officer of Miyun Town, set off as a whole army.

When the various departments of the Ming army opened the large camp, each lined up in an orderly manner and marched northward, the Ming army was extremely prosperous, including Li Fuming, the general soldier of Shanxi, and Wu Sangui, the general soldier of Ningyuan, who were in Songshan at this time, a total of 210,000 people, like a red wave that seemed to reach the horizon.

Some people died, but not completely......
