Maybe I really chose a good place, but in the past half a day, I found that someone had dug up quartzite. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

"Okay, this is it." Su Yang is in a good mood, and now he can solve the problem of solvents.

The biggest role of quartz sand is to make slag, whether it is copper smelting or iron smelting, and at the same time, once this thing comes out, it can keep the secret of bronze to some extent.

Because the natural copper has been used up, even if it is available elsewhere, the amount of this thing must be very, very small. There's not much cuprite, malachite or anything.

The rest, whether it is chalcopyrite or any other copper ore, is only matte copper extracted by the separation method, with a content of 20 to 70 percent, and generally 50 or 60, which is not pure copper.

If you want to get pure copper, you will use quartz sand, blow it, and finally mix it with tin ore to get a bronze alloy.

The whole process is not to mention the primitive man, even he pondered for more than half a year, and through practice, he almost understood it.

After thinking about it, Su Yang decided to get the arsenal to the ruin mountain, so that the secrecy would be higher.

To put it simply, let the kogasa burn charcoal at the foot of the mountain and send it to the top of the mountain; Hangai refined the ice copper and tin on the side of Xiyi Mountain, and then sent it to the top of Taixu Mountain; Here, he planned to hand over the responsibility of the Heavenly Wolf Elder, and after mining the quartz sand, he would also send it to the top of Taixu Mountain.

He arranged for his cronies to be blown in Taixu Mountain, and after mixing it into bronze, he handed it over to craftsmen to create weapons.

In this way, even if an enemy occupies Xiyi Mountain, it is useless and cannot get bronze; Or capture the savage area here, it's useless, take the quartz stone casually.

"I'm so witty." Su Yang clapped his hands, and the biggest hidden danger was temporarily lifted.

Immediately, he asked people to invite Elder Heavenly Wolf, and transferred some people from the Youxiong clan, and he himself took people to work here for three days to get the first batch of quartz stones. Originally, it was not easy to mine stone, but after the bronze ware, it was different.

"Elder Heavenly Wolf, in the future, the salt field and this stone field will be handed over to you to be responsible."

"Sue, don't worry!"

Well, his mantra has been learned, how can he feel uneasy.

The weather was getting warmer and warmer, and a few days later, Su Yang appeared on the top of Taixu Mountain, and the craftsmen who made the weapons had been mobilized, and the ice copper that had been smelted before had also been brought over.

The number of people in Xiyi Mountain was reduced, and there were only 300 people left, but there were 1,000 people at the beginning, there was no way, and people had to be employed everywhere when the stalls were spread.

Dakang stayed in Xiyi Mountain, and Hangai brought 200 people to Taixu to support the construction, and the first batch of burned lime was sent over, so that the wall could be built.

As long as the city wall is built, he will dare to move most of the people to Taixu and truly assemble the grandeur of a large tribe.

At the foot of the mountain, the pit of the foundation has been dug and the foundation stone is being buried, and supplies are being delivered almost every few days, and more and more people are gathering here, the total number of people has reached nearly 800 people, and all of them are capable of work.

This made the ten small tribes who joined the Taixu Alliance a little panicked, it wasn't that it was just a place to build an alliance meeting, but now it seems that something is wrong.

But it couldn't be stopped, and among the eight hundred people, more than six hundred were from Su Yang, occupying the dominant position.

"Look, mix the mortar in such proportions." He picked 100 people to learn to build walls, but it is estimated that it would be good if there were twenty or thirty people who learned in the end.

The whole construction process is well planned, using grouping and segmentation, the entire city wall is about two kilometers long, and the area under the circle is enough for the time being, not to mention that there is a mountain behind it.

The thickness of the wall is tentatively set at one foot, that is, about 33 centimeters, and the height is about 10 meters, so it will be calculated that more than 6,000 square meters of stone will be used, which is about 15,000 tons, which is definitely a huge challenge.

Fortunately, this is a mountain forest, as long as it is a stone, it can be used, no matter how big or irregular it is, once it is completed, even if the mammoth comes, it is useless.

I feel that there is still not enough manpower, but there is no way, it is the limit to be able to mobilize 800 people, and it is necessary to ensure that the materials can keep up, and the mammoth is still needed to save the city, and the tons of meat have made a great contribution to the construction of the tribe.

At this time, after the lime mortar was mixed, he grabbed a wooden board that looked like a shovel, scooped a lump of mortar, and with the other hand, grabbed a stone and glued it to the base, and it didn't take long to build a zigzag.

Immediately after that, five living beasts were carried over, slaughtered on the spot, and the blood of the beasts was poured on them, which was the sacrifice.

He didn't hold a grand sacrifice, and when it was finished, he didn't dare to ask for a height of ten meters in the early stage, and if there was a five-meter high, he moved the clansmen over.

"Alright, let's get to work."

Immediately a hundred wall builders were paired with two hundred auxiliary ones, and the lively action began, and he rode the Kui ox back and forth, and when he encountered the unqualified ones, he was called to stop, and then he was asked to see the ones that were slightly better.

Using this method of selection, elimination, learning, and re-employment, if there is really no talent for building walls, he will continue to train in the second phase, it can be said that there are 800 people here, each of whom has the opportunity to try, and in the end only the best is left.

The city wall is no joke, if it is built, it suddenly collapses one day, and it is called a tragedy.

Fortunately, the technical content of this kind of city wall is not high, just like playing Tetris, trying to find a way to pile up irregular stones up, the most difficult thing is that he requires horizontal and vertical, these four words are the most difficult to grasp.

For example, the person in front of him has been built a foot high, but it is crooked, and the foundation is like this, can you still expect it to not collapse when it is ten meters high?

Of the 100 people he trained in the first phase, only fifteen were left in the end, and he was also drunk, but he was not discouraged, and believed that he would get better and better in the future.

After being eliminated, he went to work as a coolie, and there were many other things that needed to be done, and although he didn't seem to be working, he was actually under a lot of pressure, and he slept less than ten hours a day, uh, in fact, it was okay.

Progress on the top of the mountain is still relatively fast, the furnace is completed, the converter is also under construction, and it will not be long before the bronze can be produced.

Lime was a little unable to provide for it, so he gritted his teeth and once again dispatched 100 people from Xiyi Mountain to run the transportation, and once again gathered 100 boy scouts to devote themselves to the construction.

With such a large investment, the results are also remarkable, the wall is rapidly increasing in height, the bottom meter has been connected, and with the foundation, it becomes much easier to stack on the top.

Unconsciously, it's the day of the ruins, in fact, it's not appropriate to talk about the full moon to catch the ruins, because those small tribes can come over to trade at any time, but the power of inertia is very great, even if you don't change anything, when it comes to the day of the ruins, most of the tribes will still send people.

Especially if there is such a big movement, how can it not attract the attention of other tribes, and there is just the opportunity to come and observe it openly.

Su Yang doesn't care, just visit, not only to see, but the warriors of the small tribes in the alliance are building walls, and even this skill has been learned. But the small tribe had no labor, no lime, and could not build such a magnificent wall after learning.

But to his surprise, Taixu came to a person who shouldn't have appeared! (To be continued.) )
