(It's Monday again, and the brothers are helping me get the red ticket!) In addition, the collection is almost 6,000, work hard, brothers who don't collect, please collect it! If it's enough for six thousand, it will explode! ）

Xiao Tianjian took this drawing away, revealing a drawing below, several craftsmen looked down, the style of the things drawn on this drawing was very strange, it seemed to be a city wall structure drawing, but it was not very similar, so they all looked up at Xiao Tianjian, waiting for Xiao Tianjian to answer their questions.

Xiao Tianjian held a carbon bar, pointed to this picture and said: "This picture is a new type of walled wall structure diagram, I call it a fortress-style walled wall, the most important thing here is these protruding positions, let's take a closer look!"

These raised positions resemble towers on ordinary city walls, the upper half is a hollow structure, in which soldiers can be hidden, and there are also shooting holes on both sides, some light artillery can be arranged, and they can also be used as barracks for officers and soldiers on weekdays!

Outside the rammed earth wall, there are ready-made stones here, it is best to put a layer of stones, if you can't complete it in a short time, you can do it slowly in the next step, but the main body of the rammed earth wall must be completed first! Xiao Tianjian pointed to the things drawn on the drawings and explained to the craftsmen.

"General! Can you ask the little one, the little one is a little confused! A craftsman cautiously interrupted Xiao Tianjian's words and said to Xiao Tianjian.

Xiao Tianjian nodded and said, "If you don't understand, just ask!" It's best to ask clearly, don't be confused, it's not beautiful to get it wrong when the time comes! ”

The craftsman boldly pointed to the drawings and said: "General, the city wall is not built like this, it is so convex and concave, and it is inconvenient to fire arrows and cannons at the battlements on the wall!" What's more, if these upper perforations are opened like this, the people inside will not be able to shoot outside, whether they are firing guns or arrows! If you don't get one right, you'll hit the opposite wall! How can a general be so regulated? ”

"Hahaha...... Speaking of which is on the point! Good! You're very careful! Hehe! It's time to ask!

Let me explain it to you! You see, if the walled wall is built like this, although the thickness is only less than two zhang, but if you look closely, what is the thickness from here here? ”

Xiao Tianjian pointed to the raised position on the drawing, pulled a straight line, and asked several craftsmen.

When several craftsmen saw it, they immediately exclaimed: "If you look at it like this, wouldn't the wall be widened?" Looking at it this way, if the wall is one and a half zhang thick, it is at least several zhang thick! ”

"Yes, it is through this kind of folding that the edges and corners of the protruding wall are pointed outward, you think about it, if the enemy wants to use artillery to collapse our wall, is it still possible? I estimate that even if we don't use stones to put a layer on the outside, even if this official army pulls a few Hongyi cannons, I'm afraid it will be difficult to collapse our wall!

Look again! The positions of these perforations, you said are really good, the perforations are opened here, and they can't hit the enemy troops outside at all, but can the enemy troops hit these places?

If the enemy wants to lean the ladder against the wall, they must enter these hollows and look at the perforations on both sides! Hum! If they dare to rush here, this is their burial place! Xiao Tianjian then took a charcoal pen and explained to these people.

Everyone, including Zhang Chao, after listening to Xiao Tianjian's explanation at this time, combined with the drawings, immediately sketched the appearance of this so-called fortress-style walled wall in their minds, and at the same time sketched a scene when the enemy attacked in their minds, and then thought about the location of those perforations, several people gasped almost at the same time.

Because only now did they really understand Xiao Tianjian's The poison of the wall, such a wall, does not pay attention to the defense of the frontal enemy at all, but most of the firepower, are pointed to both sides, that is, between the two protrusions, the enemy bombards with artillery, such a walled wall is not afraid of them at all, the wall at the corner is not penetrated at all, and the enemy can only rely on people to attack the wall, and they are at the edges and corners, they must not be able to erect ladders, so if they want to rely on the wall, they must enter the depression of the wall.

But once the enemy enters the depression, they will find that they have fallen into the trap, and no matter which side of the wall they lean the ladder on, they will be shot by the defenders from behind, so to speak.

And even if they climb halfway up, the hollow position above, the defenders hidden inside, can poke out their forks, knock down the long ladder on the wall, or stab the enemy lying on the ladder with a spear, this move is really vicious, if such a wall is really built according to Xiao Tianjian's requirements, for any attacking side, this place will become their nightmare.

Therefore, this kind of walled wall does not focus on the development of frontal firepower, but highlights the development of side firepower, forming effective cross-fire in the place where the enemy attacks, and at the same time using this structure, greatly enhancing the stability of the walled wall, heavy siege equipment has no way to take it, and the cannon is also in vain.

Xiao Tianjian smiled at them and asked, "After I said this, is there anything I don't understand?" ”

The craftsman who asked out loud immediately bowed down and said to Xiao Tianjian: "The little one is blunt, at the beginning, I really didn't understand why this walled wall was built like this, but now the small one understands the meaning of the general, it turns out that if the walled wall is built like this, even the gods may be very difficult to attack!" ”

"I can't say that, if the number of enemy troops exceeds that of us by dozens of times, and we are not afraid of death, then we may not be able to attack it, hehe! It's just that I'm afraid that with the quality of the officers and soldiers, not many soldiers are willing to work so hard!

By the way, the big guy looks at the gate again, the gate here also has to be rebuilt, the gate must be opened towards the side wall, in this way, if the other party wants to hit the door, it must have its back to the side wall, and there is no big crash here, in short, to build our enemy, as soon as we get here, we can only hit the head and bleed back! Big guy see what's wrong?

This is just one of my ideas, the specific details, it depends on you to improve, how to build, the big guys discuss together, elect a steward, everyone listens to the steward's arrangement! Xiao Tianjian dropped the carbon bar, clapped his hands and said to everyone.

A few craftsmen pushed me to let me, and finally under the recommendation of Zhang Chao, a craftsman was appointed as the manager of the wall repaired this time, this person was the craftsman who just asked the question, Xiao Tianjian asked him his name, and learned that this person's surname was Lin and his name was Lin Baotian, so Xiao Tianjian gave him a name and called him the chief engineer of the Shuangfeng Zhai fortifications this time, referred to as the chief engineer! So the first chief engineer of the Xingtian Army was so freshly baked.

And the reason why Xiao Tianjian would consider building the wall of the important part of Shuangfeng Village into a fortress-style wall, in addition to operating this place into a strong fortress that makes the enemy look at the headache, there is also a reason that because in a short period of time, it is impossible for the Xingtian Army to cast heavy artillery, if it is to build an ordinary wall, once one day they attract a large number of officials and soldiers to suppress it, and the officials and soldiers pull in heavy artillery, especially if they get one or two heavy Hongyi cannons, put them in the distance, and bombard the wall, it is estimated that they will only stare and be beaten. In this era, the power of the Ming Dynasty, whether it is imported or imitated, is already considerable, and the ordinary city wall cannot withstand repeated bombardment, so since it is very important here, then it will not be stingy with labor, spend more money, and directly build the walled walls in several key places into walled walls similar to the fortress style, so that the officials and soldiers can not take them with heavy artillery!

However, he also did not think of building the entire Shuangfeng Village into a fortress, after all, building a fortress is an extremely labor-intensive and financial thing, with his current situation, if he wants to build a large fortress that is serious, there is no such possibility, so he can only be simple because of the simplicity, the wall at several key points is designed to be similar to the simple fortress-shaped wall, so that for the Shuangfeng Village, it is enough, and the amount of work can also be limited to his ability.

However, even so, the amount of work to build such a walled wall is much higher than the amount of construction of an ordinary walled wall, and of course the cost will be larger, and the amount of labor will be many times higher than the construction of an ordinary wall, but Xiao Tianjian does not consider these things now.

With the current reputation of the Xingtian Army among the local people, the common people will definitely be willing to help them, especially now that it is the time when the green and yellow are not available, the common people do not have much food in stock, as long as the cauldron is set up and the people who come to help are fed, it is estimated that there will definitely be no fewer people who come, so there is no need to spend money to hire labor, and only need to invest a batch of food to basically solve the problem.

As for the materials, cut down the woods in the west, the wood is no problem, and there is loess at the foot of the mountain, and there is limestone very close to here, and then burn some lime, and his subordinates want carpenters to have carpenters, and stonemasons to have stonemasons, there is no problem in doing these things, and he does not plan to use glutinous rice juice to mix it into the soil to build a wall, glutinous rice is really hard to find now! Therefore, if the existing materials are used to build this fortress-style wall, it will not cost much money, mainly because of the expenditure on food.

But this problem will not be too big, now he has sent Yan Chongxi and a group of people out to fetch grain, they must have shipped back a batch of grain a year ago, and he will send people to take turns to go out to fetch grain after the year, so as long as there is no big change, he should not run out of food, and there is another advantage of doing this, that is, it can attract the local people not to go out to flee the famine, stabilize the people on this land, feed them with work relief, and make full use of their manpower, so as to rebuild the wall here, There shouldn't be much of a problem.
