The problem he encountered was so serious that he had no clue.

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

It wasn't that the stone was too hard to chisel, or that his strength was too small, but that he couldn't make a regular circle on the stone slab that was about to make the stone mill.

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

It's really helpless to say, the matter of digging a stone mill, he was actually stumped by such a thing that he had never thought about at all.

He tried for a long time on the granite slab but could not draw a regular circle, and in desperation, he had to go to the carpenter for help.

After listening to the words of the wood, he came without saying a word, but he was a little disappreciative in his heart, isn't it just a circle? It's a simple thing.

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

It turns out that seemingly simple circles are not at all simple to draw.

The stone that often holds the 'pen stick' passes by here, and after understanding the dilemma between the two, he volunteered to do it.

The circles he drew were a little worse than the ones they drew with a cripple of wood.

After a while of unsuccessful attempts, the clever and studious stone was also made lose his temper by this simple circle.

Wanting to ask Miko for a solution, Miko went to Salt Mountain, and after hesitating for a while, he had to go and ask the second wise man in the tribe.

Wu has enough enthusiasm for making soybeans from beans, and when he heard about it, he immediately came over.

After some comparisons, he was also helpless.

For a while, several people were holding their heads here in a painstaking meditation form.

A simple circle that overwhelms them all.

Wu scratched his scalp in anguish, and his hair fell out of many roots, so that the already thinning hair became even thinner, speeding up the process of approaching the Mediterranean......

At this time, Han Cheng was in Yanshan.

After explaining the structure of the stone mill to the wood, he took the army of dogs and some people from the tribe to the salt mountain.

The stone grinding can be explained to them for the wood to do, and the salt brine needs to be done by him in person.

At this time, there are many changes in Shioyama compared to a few years ago.

The desolation has decreased a lot, and there are many more people.

In one part of the salt mountain, there are a lot of rubble scattered there, and there are more traces of human chopping on the stone wall.

This is the traces left by the people of the Qingque tribe who have been beating the salt mine here for a long time to boil salt.

Not far from the salt mountain, the spring that has been expanded and rested, and downstream, the vegetation does not grow vigorously.

On the one hand, it was trampled back and forth by the people who boiled the salt, and on the other hand, it was not unrelated to the thin layer of hoarfrost on the ground.

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

This is the first wound left by the people of the Qingque tribe on this land with the continuous development of human civilization.

The salt mine is smashed, placed in a large stone mortar and smashed into a foam as much as possible, and then put into a large clay pot filled with water and stirred and melted.

After a little precipitation, wrap the mat in a linen cloth wrapped in charcoal and begin to strain......

The people who often come to boil salt have already become extremely skilled in this matter.

But this time it was different.

In the past, a basin of water dissolved with salt powder was filtered to the end, and the remaining turbid sediment would be discarded, but this time Miko did not do this, but had the turbid water mixed with a large amount of fine stone foam left and stored in a clay pot.

Although they didn't know what the Son of God wanted for these things, they did it anyway.

Han Cheng wanted these things, of course, to make salt brine.

His idea was very simple, the previous process made salt, and the salt brine was in the filtered out.

Salt brine is a very toxic thing, mainly because there are many chemical components, and some people can't think of suicide by drinking salt brine, and he has also heard of it.

The salt mines that have not been filtered, purified, and purified will also be poisoned to death after eating too much.

Contrasting the two, it's not surprising to know that the salt brine is in the filtered out.

What made Han Cheng feel embarrassed was how to extract the salt brine from these impurities.

He was stunned for a while at the turbid clay pot, and Han Cheng, who couldn't think about it, only felt that his head was big for a while.

Crossing 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, the prophet will change the direction of history quietly and invisibly.

But directly traveling to this era, it's really a bit blind.

Every time he touched on the knowledge of physics and chemistry, Han Cheng basically felt a sense of frustration that he had nowhere to go.

"Cook them too."

Han Cheng, who has a big head, can only be a dead horse as a live horse doctor, whether he can do it or not, if he has a stab or not, he will stab two poles first.

Even if the method is unreliable, it is better than sitting here and not moving, and there is no way.

When the person who boiled salt heard Han Cheng's words, he was a little stunned, could it be that these things that had been poured out in the past could also be boiled with salt?

I was puzzled, but my subordinates were not slow, and soon another clay pot was erected.

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

After a while, the water boiled and the white vapor steamed, and at the same time, the water became more turbid.

Han Cheng, who was standing on the sidelines and watching, couldn't help but sniffle, the possibility of wanting to use such a rough method to get salt brine was really not very big.

The flames continued to burn, and the water in the clay jar gradually disappeared, and something white appeared at the bottom of the pot, mixed with a lot of fine stone foam.

Han Cheng made the fire stop, took a small spot out of it, and licked it lightly with the tip of his tongue.

The flavor is full, and in addition to the saltiness of salt, there are some messy flavors mixed in with it.

Although he couldn't tell what it was, it was certain that the taste wasn't wonderful at all, and just licking it made Han Cheng grin.

And with this licking, some stone foam was left on the tongue, which was extremely uncomfortable.

Han Cheng rinsed his mouth for a while before relieving himself.

This kind of taste is estimated to be only able to bear Uncle Lu, a pervert who used to practice his tongue against Yanshan.

Han Cheng, who had rinsed his mouth, picked out the small white pieces mixed with the stone foam little by little, and his face was entangled.

Now the question is, is this thing salt brine or not?
