I am a Primitive Man

The problems encountered by Wood are so serious that he has no clue.

That is, he could not chisel a stone into a column that was not too thick.

It's not that the stone is too hard to be chiseled, nor that his strength is too small, but that he can't draw a regular circle on the stone slab that will be stoned.

If he can't draw a regular circle, he can't chisel a regular round stone.

It's really helpless to say that the excavation of stone was actually embarrassed by such a thing that he had never thought of.

He tried for a while on the granite slab, but failed to draw a regular circle. In desperation, he had to limp to the carpenter for help.

After listening to Mu Mu's words, I came without saying a word, but I felt a little disapproving in my heart. Isn't it just a circle? What a simple thing.

As a result, after picking up the stone and painting on it for a while, the limp also wilted.

It turns out that a seemingly simple circle is not easy to draw at all.

The stone that often holds the ‘pen with the pen’ passed from here. After understanding the dilemma between the two of them, they volunteered to do it.

Although the circles he drew were better than those drawn by wood and lame, they were still a little worse.

After trying for a while, all ended in failure, the smart and easy-to-learn stone was also lost temper by this simple circle.

Wanting to find a solution to the son of God, the son of God went to Salt Mountain. After hesitating for a while, he had to ask the second wise man in the tribe.

Wu had enough enthusiasm for making soybeans from beans, and after hearing about this, he immediately came over.

After some gestures, he was also helpless.

For a time, several people were thinking and meditating here with their heads in their heads.

A simple circle embarrassed all of them.

The witch scratched his scalp in distress, and his hair lost a lot of roots, so that the sparse hair became thinner, speeding up the process of approaching the Mediterranean...

Han Cheng is in Yanshan at this time.

After explaining the structure of the stone mill to Wood, he took the army of dogs and some people from the tribe to Salt Mountain.

Stone milling can be accounted for and let the wood make them, but he needs to come personally.

The Salt Mountain at this time has also undergone many changes compared to a few years ago.

The barren scene has been reduced a lot, and a lot of people have become more crowded.

A lot of rubble was scattered in a place in the salt mountain, and there were more traces of man-made chopping on the stone wall.

This is the traces of people from the Qingque tribe who have been hitting the salt mines to cook salt for a long time.

Not far from the Yanshan Mountain, around the spring that was expanded and renovated, as well as downstream, the vegetation is not growing vigorously.

On the one hand, the people who boiled the salt trampled it back and forth, and on the other hand, it had nothing to do with the thin layer of hoarfrost on the ground.

This is a man-made saline-alkali land, and it is foreseeable that this saline-alkali land will continue to expand over time.

This is the first trauma left by the people of the Qingque tribe with the continuous development of human civilization.

The salt mine was smashed, placed in a large stone mortar and smashed as much as possible, and then placed in a large pottery pot filled with water to melt.

After it settled a little, the mat was wrapped in linen wrapped with charcoal, and then began to filter...

People who often come to boil salt for this matter are already extremely skilled.

But this time it was different.

In the past, a basin of water in which salt mineral powder was dissolved, filtered to the end, and the remaining muddy sediments would be dumped. This time, the **** child did not do this, but made people mix the muddy and mixed A large amount of water of finely crushed stones was left behind and stored in a clay pot.

Although they didn't know the use of these things, they still did.

Of course, Han Cheng wanted these things to make bittern.

His idea is very simple. The previous procedure produced salt, and the bittern was among the things that were filtered out.

Bittern is a very toxic thing, mainly because there are many chemical components. Some people can't think of drinking bittern to commit suicide. He also heard about it.

As for salt mines that have not been filtered, purified, and purified, people who eat too much will also be poisoned and die.

Comparing the two with each other, it is not surprising to know that the bittern is in the filtered items.

What embarrassed Han Cheng was how to extract the bittern from these impurities.

Facing the muddy pot of stone, Han Cheng was stunned for a long time, and the unimaginable Han Cheng only felt big for a while.

Traveling through this matter is really not suitable for liberal arts students.

If you have traveled to a familiar dynasty, as a liberal arts student, you can also use familiar poems to slap historical celebrities in the face, or according to the familiar historical process, you can change the direction of history by prophesying foresight. .

But when I went straight to this era, I was really blinded.

Every time when he involved knowledge of physical chemistry, Han Cheng basically felt a sense of frustration that he had nowhere to go.

"Boil them too."

The big-headed Han Cheng can only be a dead horse as a living horse doctor. Whether he can do it or not, he will have to stoke two shots before he can.

Even if the method is unreliable, it is better than sitting here and being melancholy, there is no other way.

The salt-boiler was a little startled when he heard Han Cheng's words. Could it be that these things that have been dumped in the past can also cook salt?

I was puzzled, but his men were not slow, and soon they set up another pottery jar.

Pour the muddy water mixed with many stone foams into it and start boiling.

After a while, the water boiled and white gas evaporated. At the same time, the water became more muddy.

Han Cheng, who stood by and watched, couldn't help but sniffed. The possibility of using such a crude method to obtain brine is really not that great.

The flame continued to burn, and the water in the pottery jar gradually disappeared~www.wuxiahere.com~ Some white things appeared on the bottom of the pottery jar, mixed with a lot of fine stone foam.

Han Cheng asked people to stop the fire, made a little bit from it, and licked it lightly with the tip of his tongue.

The taste is full, in addition to the salty taste, there are also some messy tastes mixed in it.

Although he couldn't tell what the smell was, it was certain that the smell was not wonderful at all, and Han Cheng couldn't help grinning just by licking it.

And with this licking, some Shi Mozi remained on the tongue, which was extremely uncomfortable.

Han Cheng rinsed his mouth for a long time before relieving himself.

It is estimated that only Uncle Lu, a pervert who used to practice his tongue against Yanshan, can bear this kind of taste.

Han Cheng, who had rinsed his mouth, picked out the small white lump mixed in the stone foam a little bit, his expression tangled.

Now the question is, is this stuff bittern?
