Liu Shengyuan's effect was very fast, and it didn't take long for him to select two groups of strong laborers from the city, and a group of people were handed over to Yang Meng to lead, and let Yang Meng take this group of people, holding ropes, stone chisels and other equipment, to the top of the mountain on both sides of the valley, and choose a place to set up a rolling stone trap.

The other group, mostly composed of masons who were proficient in construction, were prepared to go to the valley to find a suitable place to build a low wall, according to Yang Zheng's instructions.

Yang Zheng led dozens of Han laborers, holding mud buckets and brick knives, carrying construction tools such as shovels and iron drills, and pushing several wooden carts filled with clear water lime, and went out of the city with great interest.

Among these construction laborers, there is a master master, called Lao Sun Tou, who is about 50 years old, has been a mason all his life, and his construction skills are very good, so those Han laborers in the city respect him very much.

It is said that in the past, when the Khitan people were still in Qingshi Fort, they specially asked Lao Sun Tou to be responsible for the construction of houses in the city, as well as the reinforcement and repair of the city defense.

Lao Sun Tou and others, after leaving the city, followed Yang Zheng all the way, Yang Zheng didn't say where he was going, nor did he say what he was going to do, in short, it made the group of builders behind him very puzzled.

Yang Zheng was in the long and narrow valley, so he walked and watched.

After turning almost two corners in the valley, they were already about five or six hundred meters away from the gate of the Bluestone Castle.

At this time, the road at the bottom of the valley suddenly contracted and narrowed, from a width of more than ten meters at the beginning, to only five or six meters wide.

Standing in front of this narrow pass, Yang Zheng stopped, looked up at the front of the road, and saw that this section of the road dozens of meters long was the narrowest place in the entire valley, and if you want to build a defensive low wall in the middle of the valley road, it is best to choose here.

Thinking of this, Yang Zheng immediately waved his hand, "That's it." ”

Hearing this, Lao Sun Tou immediately asked the big guys to stop, and then walked up to Yang Zheng and said respectfully: "Castle Master, what are we going to do?" ”

Yang Zheng glanced at him and said with a smile: "I want you to build a low wall here for me and seal the entire valley." ”

The old grandson was stunned for a moment, "Are they all sealed?" Do you need to set aside a door? Otherwise, the men and horses in our fort will not be able to enter and exit? ”

Yang Zheng shook his head and said: "At present, our Qingshi Fort has enough grain and grass, and for the time being, there is no need to go out." The main purpose of building this low wall is to defend against enemy invasion, and if the situation of Bluestone Fort is stable in the future, it will not be too late to demolish this low wall. ”

Hearing this, the old grandson nodded, "Castle master, I don't know how high and thick this defensive low wall will be?" ”

Yang Zheng thought for a while, then took out a branch and hastily drew a picture on the ground, "Build according to the appearance I painted, the wall should not be too high, as long as it is higher than the top of the head, if the thickness is two, at least it can withstand the impact of giant trees, and in addition, some square holes should be built in the low wall, so that it is convenient for people in the wall to observe and shoot arrows......

The old grandson listened to it in his ears and remembered it in his heart, and nodded again and again.

Because I had a rough outline of a building in my heart, soon, Lao Sun Tou arranged for everyone to start work.

Sprinkled with water and mud for drenching water and mud, carrying stones for carrying stones.

All of a sudden, in the middle of the valley, the masons were busy.

Yang Zheng called the old grandson aside and asked in a low voice, "Can it be completed before sunset today?" ”

Old Sun Tou lowered his head and thought for a while, and said, "As long as the stone supply is timely, half a day is enough to complete it." ”

Yang Zheng nodded with satisfaction, "This is very good, after it is completed, I will reward you heavily." ”

As soon as these words came out, dozens of masonry craftsmen present were smiling happily and working harder and harder.

With the continuous supply of stone in the city, the defensive wall was built very quickly, and it took less than an hour to build a stone wall more than one meter high on the road.

Yang Zheng was very satisfied with the progress of the project, nodding his head from time to time to praise them, and occasionally ordering some tea, wine and meat to come from the city, which flattered the gang.

This low wall is very important to Yang Zheng.

He plans to deploy this place as the first line of defense of Bluestone Castle, and it is also the most lethal line of defense.

As soon as the defensive low wall is completed, when the time comes, Yang Zheng will install the two Czech light machine guns stored in the infinite armory.

With two light machine guns, there are many holes in the low wall that are convenient for shooting, and when the time comes, five AK47s can also be placed here.

In the face of two light machine guns and five AK47s in the low wall, no matter how many enemies rush in front of you, you will definitely not be able to get close to the low wall for 100 meters, and you are guaranteed to let as many enemies come and die.

Just now Yang Zheng carefully observed the environment in this area, both sides of the low wall are steep stone walls dozens of zhang high, there is no need to worry about the enemy will attack from above, even if the enemy ventures to climb to the top of the mountain, Yang Zheng can also arrange some gunmen to keep an eye on the defense.

Outside the low wall, there is a straight valley road hundreds of meters long, which is extremely open to the eye, and at the same time, that section of the valley road is completely exposed to the range of machine guns.

The widest part of the valley road in front is only less than 20 meters, and two light machine guns are placed here.

Standing at the construction site and looking at it for a while, he felt a little bored, so Yang Zheng immediately returned to the city tower and prepared to observe around the city defense to see if there was anything that needed to be strengthened.

As soon as he ascended the city tower, he smelled a strange fragrance coming into his nose, Yang Zheng's heart moved, and when he looked back, he found that Lian Bijun appeared behind him at some point.

I have to say that Lian Bijun is indeed a very rare beautiful woman, not only with exquisite facial features, but also with a tall and plump figure.

She and Yang Zheng stood side by side on top of the city tower, and they were almost as tall as him.

After two days of cultivation, Lian Bijun's complexion returned to normal, and his gorgeous face was more radiant than before.

Looking at the sunset gradually setting in the west, Lian Biyun suddenly said, "I'm curious. ”

"Curious about what?" Yang Zheng turned his head to look at her, and found that there was a strange light flickering in her watery eyes.

Lian Bijun sighed faintly, "I'm curious, how did you capture Bluestone Fort with more than 100 men and horses that night?" ”

Yang Zheng said casually: "The Khitan people are loose and arrogant, so we have a chance to take advantage of it, if it is under normal circumstances, it will be difficult for our men and horses to capture Qingshi Fort." ”

Hearing this, Lian Bijun's beautiful eyes flashed, and he said with a smile: "Lord Yang Bao is not simple, not only can he capture Qingshi Fort with more than 100 men and horses, but even with more than 100 laborers, he can easily break through Panlong Town and loot the food and materials of the Qinglong Gang. ”

Yang Zheng said casually: "What does Miss Lian want to say?" ”

Lian Bijun looked at his eyes deeply, and said lightly: "Has Lord Yang Castle ever thought of joining Chishui City, my father cherishes talents the most in his life, you are so capable, if you can serve Chishui City, in the future, in this Western Wilderness, you will definitely be able to shine and have a bright future!" ”

Yang Zheng shook his head and smiled, "I'm a person who naturally likes freedom, and I don't want to be controlled by anyone, so it's better to join Chishui City." ”

Speaking of this, he paused, looked at Lian Bijun with a playful expression, and said slowly: "However, if you can stay and be my concubine and warm the bed for me, I will consider considering forming an alliance with you Chishui City." ”

Seeing that his words were light, even Bijun was not angry, but just smiled faintly, "You really dare to think about it." ”

With that, she floated away without looking back.
