"Alas......"

Ye Xi touched the kaolinite clay in his hand with his fingertips, and suddenly sighed deeply.

Although he is anxious now, he can't wait to build 10,000 stone houses from the ground now, but the steps that should be completed still have to be completed, the nine-story platform, starting from the soil, can't build a house in one step, and can't become a fat man in one bite.

Ye Xi brought people in and began to give orders one by one, assigning work in an orderly manner.

"Pingyao, you let Chief Youshi lead the way, and immediately lead a hunting team to mine a large number of this clay block, and put aside the matter of mining bluestone for a while. ”

"Chief Nest, you lead another hunting party to mine limestone. ”

"Chief Gongtao, you can help select twenty excellent craftsmen, and you will come with me later. ”

The three of them responded in unison: "Yes!!"

The two thousand-man hunting brigades were quickly cleaned up and set off in a majestic manner.

The twenty craftsmen of the pottery were also quickly found, Ye Xi nodded at them and led them to hurry towards the cave.

Although the materials are ready, it is still not easy to make cement in this prehistoric and barbaric era.

The first problem was that all the excavated limestone blocks, as well as the kaolinite clay blocks, had to be ground into a fine powder.

Ye Xi asked everyone what they would do if they were asked to grind the stones into powder, and the answer they got was that they would first smash them with hard rocks, and then crush them one by one after they were smashed into gravel.

Obviously, this method is cumbersome, time-consuming, and if you are not careful, there will be small stones mixed together, and it is not easy to pick out, and it will be very troublesome in the later stage.

Therefore, Ye Xi led the craftsmen of the pottery and asked them to make ten improved versions of the stone mills according to the drawings.

Grinding powder with stones is definitely much more efficient than smashing with rocks, and it is more labor-saving, even children with more strength can help.

It is not enough to have stone grinding powder, people are not machines, and it is inevitable that they will accidentally leave hard small pieces that are not ground, so Ye Xi led the Qiao woman to make a few large sieves with oil-soaked fine rattan, and told everyone to carefully sift the stone powder with a fine sieve after grinding it to ensure that no small stones are mixed in it.

Wait for the powder to finish grinding and sifting.

Ye Xi mixed limestone powder, clay powder, and iron ore powder evenly in the proportions of 8/10, 2/10, and 1/10 respectively.

I have to mention here that in fact, iron ore powder should be the most difficult to find, but Ye Xi and they are very lucky, the main component of the big meteorite hidden by the Zhu tribe is iron, and the amount of iron powder needed to make cement is very small, so it is enough.

After the three materials are mixed, the resulting material is called cement raw meal, and it is also calcined.

If you want to calcin, you must have a kiln, and burning cement is not burning ceramics, and ordinary kilns are not working, so Ye Xi racked his brains, and the craftsmen who led the pottery spent two days tossing out the original version of the manpower rotary kiln.

A few days later, after the manpower rotary kiln was made with great painstaking work, and everyone calcined the cement raw meal into mature material, Ye Xi suddenly slapped his head and said with remorse: "...... Oops, forgot to look for plaster!"

Cement clinker should be finely ground with gypsum, and it is real cement after being mixed in proportion.

Without gypsum, he didn't know what the cement looked like.

Everyone was taken aback by Ye Xi's appearance.

Ye Xi has always been calm, mysterious and omnipotent in everyone's impression, even when the meteorite shower descends, he looks calm. Leng Buding showed such an annoyed look, and everyone couldn't help but feel worried and panicked.

Although none of them knew what a plaster was......

Seeing that it had caused everyone to panic, Ye Xi suddenly didn't dare to show his annoyance, so he barely picked up a confident look, and forced a smile to appease everyone.

But after returning to the cave, he was still anxious.

After tossing for so many days, he saw that it could be completed with one kick at the door, but he was delayed here, how could he not be in a hurry......

Although he no longer showed it on his face, his body was very honest, and after a night, two small crystal bubbles grew next to his mouth, and he was dragged by the sharp-eyed doctor witch to heal him.

In fact, the reason why Ye Xi was in such a hurry, in addition to the fact that the day of winter was getting closer and closer, was also because he was worried about the people of the Xia tribe. The Xia tribe was too weak, Ye Xi was really difficult to feel at ease, and originally thought that after the construction here was on the right track, he would immediately set out to take over all the Xia tribe people.

But it dragged his feet again......

In fact, it's no wonder Ye Xi.

Because of the production method of cement, Ye Xi heard it from a home improvement worker by chance in his previous life, and it is remarkable that he can still remember so much after so many years, and it is really normal to miss a plaster.

But fortunately, Ye Xi didn't rush for long.

Things soon took a turn for the better.

On the second day, Ye Xi suddenly remembered that he had heard from the tribesmen that there was a huge rock salt mine cave about twenty miles away from here.

That rock salt mine contains an endless supply of natural rock salt, which was discovered by a small tribe by chance a hundred years ago. This small tribe developed the rock salt mine into a mining cave, and slowly developed it with the help of rock salt, and finally changed its name to the Youxian tribe.

Originally, relying on this huge wealth, the Youxian tribe could develop steadily, but unfortunately, more than ten years ago, they unfortunately encountered a powerful beast.

The ferocious creature was very satisfied with the rock salt mine cave of the Youxian tribe, and overbearingly drove away the people of the Youxian tribe and occupied this big mine.

The Xian tribe couldn't beat it, and later relocated, and there was no news again.

Ye Xi has always kept this rock salt mine cave in his heart since he heard the tribesmen say this.

Because the hunting team had never found saline-alkali land when they were hunting, nor had they found natural salt producing areas such as salt lakes and salt springs, Ye Xi planned to wait for the cement matter to be settled, and then free up his hands to deal with the murderous thing and occupy the rock salt cave.

But now that he was in dire need of gypsum, it suddenly occurred to him that there was gypsum among the companions of rock salt!

Thinking of this, he couldn't sit still any longer, and immediately led all the fifth-level warriors of the alliance to fly towards the rock salt mine cave on three fierce birds, the big bustard, Qingtian and Daxue, and finally joined forces to kill the murderous thing.

This huge rock salt mine cave is nothing short of spectacular.

The people of the Xian tribe mined this rock salt mine from the bottom of the mountain like digging a cave, and when they stepped inside, the crimson beautiful rock salt was like pink crystal inlaid on the cave wall and the top of the cave, and the whole cave was filled with a magnificent crimson light under the sunlight.

At that time, the chief of Ganqi and the chief of Gongtao opened their mouths and were completely stunned.

Ye Xi was also a little dazed, and muttered, "...... It's really posted. ”

This kind of natural rock salt was ten times more expensive than ordinary salt in the previous life, and the rock salt with such good quality and such transparency is probably even more expensive, and the most important thing is that there are so many rock salts here, even if the people of the entire alliance eat it for several lifetimes, they can't eat it all!
