Zhao Hao didn't explain to Cangwu how to build this city wall, because it was too troublesome to explain this matter clearly, so it was better to show it to others directly.

Early the next morning, he took Ah Yun and Ah Yue, under the guidance of Cangwu, and walked towards a secret place in the Black Stone Department.

What are the secrets of the Black Stone Ministry?

The secret, of course, is the firing of pottery.

The people of the surrounding tribes didn't know how the Black Stone Department could fire real pottery at all, but Zhao Hao had already guessed it.

Sure enough, after entering a small inconspicuous valley, he saw a simple ceramic kiln.

This ceramic kiln is actually a small cave dug out by hand, but the inside of this "cave" is a roughly semicircular spherical structure, and there is also a chimney.

The ceramic kiln in the black stone department is not big, and there are about two or three cubic meters inside, and people have to bend their waists to get in, and every time they can bend down and drill in, if they want to enter one more person, they can't move inside.

At this time, it was the gap between the pottery firing, and a few old masters of the Black Stone Department were digging clay and kneading pottery outside, and the ceramic kiln was empty, and there was no smoke or pottery.

Zhao Hao directly bent down and walked in to take a look, as expected, the black stone department used coal to burn pottery, and there were still uncleaned cinders in the soil pit in the middle of the ceramic kiln.

He took a general look inside, then drilled out and said to Cangwu: "Can you build a bigger ceramic kiln?" ”

Ceramic kiln?

When Cangwu heard this, he was a little confused, because there was only pottery at this time, and there was no porcelain.

However, he still understood that what Zhao Hao was talking about was the hole they took out to burn pottery.

He was stunned for a moment, then nodded and said, "Of course, the bigger ones can be dug up, but there are only a few people in our Black Stone Department who can make better pottery, why dig a bigger hole?" ”

Of course, it is used to burn terracotta bricks!

The clay and coal are ready-made, and there are several old ones, but there are a few brick molds and a large brick kiln.

Still, this thing is still troublesome to explain.

Zhao Hao thought about it, simply pulled out the divine weapon, walked directly to a nearby tree thicker than his waist, brushed a knife, cut it off, and then, with a kick, kicked the trunk directly to the ground.

Immediately afterwards, he took the trunk of the tree, brushed it with a few knives, and soon a wooden brick mold appeared in his hand.

He didn't speak, he just took the brick mold, came to an old-fashioned stone platform, motioned for people to let go first, and then he picked up the clay that had been dug up next to him, and after a while, several square clay bricks appeared in front of everyone.

He pointed directly to the clay brick and said to Cangwu: "This thing, if you burn it in the kiln, will it become as hard as a stone?" We're going to use this thing to build a city wall, and you say, a few months, is that enough? ”

The platform piled up with this square thing is naturally square, Cangwu finally understood what Zhao Hao meant, it turned out that this guy wanted to use this square pottery block to build a platform!

Well, the platform built here is naturally no problem, but the problem is that it will take a few months to enclose the entire Black Stone Tribe's settlement with a high platform built with this kind of square pottery blocks, so how many of these square pottery blocks will be needed!

Cang Wu thought for a while, and then pointed to the old trick next to him and said, "Just these few people, I'm afraid it's difficult to make so many square pottery blocks in a few months, right?" ”

Pottery blocks!

Zhao Hao shook his head and smiled bitterly: "This is not called a square clay block, this is called a clay brick, just now you also saw it, making clay bricks is actually very simple, as long as there is a mold, lift the clay quickly, fall it hard, and then scrape off the excess clay with a wooden board or bamboo or something, this kind of thing, generally young people will do it, right?" ”

Well, it's really not that hard.

The question is, how big a hole do you have to dig to burn enough clay bricks to build a platform in a few months?

Cang Wu thought for a while, but still couldn't estimate it, he simply asked, "How big do you think you should dig out a hole to be enough?" ”

Hole?

Zhao Hao shook his head helplessly and said: "I said, this hole for firing pottery is called a ceramic kiln, as for how big this hole has to be, it depends on how many people you can find to make pottery bricks. ”

When Cang Wu heard this, he couldn't help but be dumbfounded.

How big is a hole that can stand in ten people!

It was bigger than the pit that was dug to catch Dangkang, the pig demon, and the mountain ointment, and this hole was not dug in the soft mud, but on the hard hillside, and one could kill a person, and ten of them were dug out!

He thought for a while, and then he wondered: "This, I'm afraid it will take a month just to dig a hole, right?" ”

Zhao Hao said indifferently: "It's okay, we have time, and the people from Xue Man's Department will not come over until at least ten months later." ”

Anyway, he doesn't have to dig this hole, so he naturally doesn't care.

Cangwu frowned and said: "Time seems to be enough, but I don't have enough manpower, if I want to call most of the young people to dig holes, who will go hunting?" If there aren't enough people to hunt, a large number of my people from the Blackstone tribe will starve to death! ”

Will people starve to death at this time?

When Zhao Hao heard this, he was also dumbfounded.

He really hadn't thought about this problem, because at this time, the people of the Salt Tribe, who couldn't eat all the meat in a day, how could he have thought that the Black Stone Tribe's would starve to death.

Of course, this problem is easy to solve.

He was stunned for a moment, and then said boldly: "You don't have to worry about hunting, I will send you 10,000 catties of bison meat every day, it should be enough, right?" ”

10,000 catties of bison a day!

Hearing this, Cang Wu was stunned again.

He hadn't been to the current settlement of the Salt Ministry, so he didn't know that the Salt Department raised cattle, let alone how many cattle the Salt Department raised.

He was stunned for a while, and then he was curious: "Where did you go to hunt so many bison?" ”

Zhao Hao said quite complacently: "There are more bison herds on the grassland, and we have collected three herds at this time, not to mention twenty or thirty thousand heads, ten thousand catties of bison meat, that is, ten cows, ten a day, only three hundred a month, ten months down, a total of three thousand, rest assured, this bison we have salt or supply." By the way, if you don't like to eat beef and greasy, we still have 10,000 or 20,000 sheep, and it's no problem to slaughter about 10 of them for you every day. ”

Can you still eat bison meat to get greasy?

When he said this, even the old man next to him fell into a stupor.

Cang Wu was stunned for a while, and then nodded heavily: "Okay, since you have caught so many bison and wild sheep, the matter of eating will trouble you, I will let all the young people in the clan come and dig holes!" ”

When Zhao Hao heard this, he thought about it again, and then nodded and said: "Okay, you wait for three or four days, and I will order someone to drive the cattle over and slaughter them next to the river valley not far from you, so as to save the time of delivering meat." ”

10,000 catties of meat a day, it is indeed very troublesome to send it from the current settlement of the salt department, and it is different to drive the cattle to the nearby canyon and kill them.
