After the bow and arrow were made, the weapons for long-range attack and melee combat were available, and then, it seemed that there was only a number of accumulations left, as long as all the strong and strong of the Black Stone Department were equipped before the people of the Xue Man's Department came to retaliate, it seemed that they would not have to worry much about not being able to do it.

Of course, this wall had to be built to be on the safe side.

In any case, it is safer to hide in the city and guard the general army in the field to fight with people.

At this time, the ten large brick kilns of the Black Stone Department have begun to produce terracotta bricks, and it is not a problem to produce tens of thousands of terracotta bricks every day, so it is time to consider the problem of building a city.

Zhao Hao silently observed in the vicinity of the Black Stone Department for a few days, and then found Cangwu, stood with him on the mountain in front of his tree house, looked at the messy thatched houses and tree houses built around, and said earnestly: "Leader Cangwu, your clansmen of the Black Stone Department live so scattered, it is very troublesome to build a city wall." ”

When Cang Wu heard this, he couldn't help but nod and said, "Well, I've also thought about this, otherwise, I'll let them all squeeze around here, so that we can build fewer city walls." ”

Zhao Hao slowly shook his head and said: "This still doesn't work, the scope is still a bit large, and besides, the place where you live now is staggered with mountains and valleys, which is extremely unsuitable for building a city wall." ”

When Cang Wu heard this, he couldn't help but say a little anxiously: "Ah, what should I do then?" ”

Zhao Hao raised his hand, pointed to an independent mountain not far away, and said wisely: "It's very good there, the valley where the brick kiln is located is much closer than the place where you live now, I have gone up to see it, there are streams on the mountain, don't worry about the water source, and the scope of that mountain is also large enough, enough to live all of your Black Stone Department, why don't we build a city there, the name is Salt Stone City, after it is built, all the people of your Black Stone Department can move to the city, We have people from the salt department who can also come to the city from time to time to fix it. ”

Build a city?

Also Salt Rock City?

What is the city?

When Cang Wu heard this, he couldn't help but have doubts on his face, he thought about it carefully, and his face couldn't help but show embarrassment.

Although the mountain is not very far from the Black Stone Division, there are thousands of people in the Black Stone Division, all of them have moved there, and after the city wall is built, they have to rebuild the thatched huts and tree houses, what a lot of effort!

In these years, if you talk about hunting and getting food, everyone is full of energy, and if you want to move, it is estimated that few people are happy, because it is too troublesome.

He thought for a while with a puzzled face, and then said carefully: "Why don't you just make do with building a city wall here, I'm afraid everyone won't want to move!" ”

Reluctant to move?

This is a question that needs to be carefully considered.

His idea of building a city was originally a good thing, but if everyone was unwilling, he forced everyone to move, which would be in vain, which was very detrimental to his future plans.

So, what should I do, how can I make the people of the Black Stone Department move to Salt Rock City willingly?

Early the next morning, he dragged Cangwu to the brick kiln, and asked Cangwu to gather a group of veterans, and then, in front of everyone, he used a large wooden stake to cut a mold.

This mold is composed of two parts, inside and outside, inside, is a cylinder with three finger thickness of the protrusion, the outside is two semi-circular arc-shaped assembly blocks, the two semi-circular arc-shaped assembly blocks are closed, just can be combined with the middle cylinder to form a larger cylinder, between the three there is a gap of three finger thickness.

After the mold was done, he demonstrated it again, first smeared the surface of the mold with fine sand, and then directly pasted the cylinder in the middle with clay, and then took the two semi-circular arcs outside to press the middle, and then scraped off the excess soil at both ends, and then carefully removed the cylinder in the middle and the cylinders on both sides, and there were three arc-shaped pieces about the thickness of a finger and the width and height of the palm of the hand.

His miraculous operation made everyone's faces full of puzzlement, everyone knows that the reason why he cut out that strange mold is to make this arc-shaped piece, the question, what is the use of this piece?

Zhao Hao still followed the old rules and did not give any explanation.

He just kept pressing tablets with a mold, pressing all over the ground, enough to have thousands of pieces, he stopped and said to Cangwu and the others: "Everyone understands, just do this, dry it again after you finish it, and wait for this thing to dry, and then put it in the brick kiln to burn it overnight, you try to make as much as possible, I will use it tomorrow and the day after tomorrow." ”

After saying that, he left everyone and walked straight to the big tree house where the iron was struck, leaving only Cangwu with a confused face and a group of old masters looking at the tiles in a daze.

That's right, the things he made were tiles, tiles for building brick houses.

Of course, to build a brick house, it is not enough to have tiles, you also have to have nails.

After he came to the blacksmith tree house, he found a finger-thick branch to sharpen the front end, and then asked Ah Hua to take a square clay block for clay molds, and then used the sharp branch at the front end to poke a bunch of holes with small nests on the clay block, and then put the clay block next to the furnace and roasted it until the clay block was almost dry, and then let Ah Hua and them burn some molten iron and pour it on it.

This time, he didn't have the patience to wait for the molten iron to cool down naturally, he just poured water from a clay pot on top of the clay mold, and then used a clamp to clip out the iron lumps that were roughly cast into the shape of nails, and put them on the fire of the furnace to roast them a little, and then they picked them up and hammered them quickly, and before long, a pile of nails with a slightly square front end appeared in the thick clay pot filled with stream water.

Ah Hua and the others were also full of confusion, because they didn't understand what this small, spiky thing was for!

Zhao Hao didn't explain, after the nails were built, he took a thick wooden stick with an arm, and then directly pulled out the divine soldier, split the wooden stick in half with a knife, and then closed the two halves and put them on the ground, and then took two more nails, directly picked up the sledgehammer, "Ding Ding Ding" is a few times, and directly knocked the two nails into the wooden stick split in half.

After knocking it out, he picked up the wooden stick, broke it slightly, and then said with a little smugness in his hand: "Try it, see if you can break it." ”

Ah Shan probably understood that this thin, pointed thing was used to put two wooden pieces together, and he took the wooden stick in his hand and broke it hard, but he didn't break it!

This is not to say that he is not strong enough, the main wooden stick is a round, not very easy to exert force, if two wooden nails together, it is estimated that even if he nails a few more nails can be broken.

However, none of this matters, what matters is, what is the purpose of splitting and closing the sticks together?

He really couldn't understand it, you said that you split the sticks and burned them as firewood, and it was better to burn them, and you put so much effort into creating a thin, pointed thing, and put it together, what was the use?

Zhao Hao didn't know that he had made a wrong demonstration, which made people feel inexplicable.

He only knew that the nail, if he did this, he could use it, although it was a disposable thing, and he couldn't take it out and use it again, but there was finally a nail.

He can then use it to build a house.
