For salt making, Yan Zheng knows that there are several methods, such as boiling salt and drying salt, which are the most common methods.

As for finding salt, there are also relevant records in the pamphlets he has read.

Mineral salt can be found, which is the best case, because it is more convenient to mine and purify mineral salt.

It has been recorded that mineral salts are generally more likely to occur in areas with low transpiration and precipitation.

This is because sedimentary salt layers are formed in the depressions of these areas due to the accumulation and evaporation over thousands of years.

In a vegetated place like the South, where there is a lot of vegetation, it is unlikely that there will be easily minable mineral salts.

Another stable source of salt is the sea, which can be boiled and dried as long as the salt content of the sea is clear.

Yan Zheng only took a look at the thatched house, and ruled out the first possibility.

The place where he was located was lush and green, with vegetation somewhat similar to that of the subtropics.

It is almost impossible to find exposed mineral salt in such a place, which is why this tribe did not know that there was salt.

Can you go to the sea?

He didn't know the bottom of his heart, he felt that with the current situation, it seemed difficult to launch a prospecting operation.

So he really felt uncomfortable at the moment, he knew what the problem was, but the objective conditions were there, which made people feel a sense of powerlessness.

The leader didn't know when Yan Zheng came behind him, and when he saw a little lonely look on his face, he also frowned.

"#¥%%......," he said with a kind smile.

Yan Zheng came back to his senses, looked at him and smiled: "You, the leader, are really stupid and stupid!" I don't know so much, so I don't have to worry about these things at all. ”

The leader muttered a few more words, as if he was reassuring Yan Zheng.

"Forget it, let's make do with it first."

Yan Zheng stretched his waist, it was too difficult to find salt, but it was not difficult to get a little salt.

He thought of how the Soviet area boiled out some salt in the face of Chang Kaishen's blockade.

"@#¥......" The leader patted him on the shoulder, motioning for him to follow.

Yan Zheng followed into the big thatched hut and found that the old man was fully awake, but he couldn't get up now.

When he saw Yan Zheng and the leader come in, he smiled and stretched out his dry hand.

The leader immediately walked over, grabbed him and whispered a few words.

The old man seemed to have phlegm in his throat, and looked at Yan Zheng as he listened.

“！ @##¥%......" The old man beckoned weakly and motioned for Yan Zheng to walk over.

After Yan Zheng walked over, he pointed his dry fingers on Yan Zheng's forehead and chanted softly.

Not only did he sing, but the leader sang along.

Yan Zheng looked at it in confusion, thinking to himself whether this was a spell or a ballad?

When he had finished singing, the old man smiled at him, and the leader beside him respectfully handed over a cane.

Yan Zheng was still a little stunned, so he instinctively took over the white crutch.

But when I looked closely, his hair stood on end, which was a cane made of thigh bones.

And then, the leader took out something that made him almost pee.

A delicate human-headed skull!

The leader handed the human head skeleton to Yan Zheng with a very solemn expression.

Yan Zheng forcibly calmed down and took it with a trembling hand.

In any case, there is nothing wrong with following others at this time.

Seeing that he had taken the human head and skeleton, the old man smiled kindly and said a few words to the leader.

The leader nodded knowingly, and walked out of the thatched hut with Yan Zheng.

With the leader's shout, the people who were close immediately rushed to the open space in front of the thatched hut.

After seeing Yan Zheng holding a bone staff and a human head and skeleton, the clansmen erupted in bursts of cheers.

Hey hoo...... Hey hoo...... Hey hoo......

Seeing this scene, Yan Zheng understood that this must have granted him some kind of recognition.

That's fine, at least from this moment on, he's a weirdo who has a place in the tribe.

The leader muttered for a while, and the people below became even more ecstatic, and they scattered and ran back to their thatched huts.

In a short time, they ran out with stone spears, stone knives, bows and arrows, and other weapons.

With a shout from the leader, the young men ran out of the tribe.

What's going on?

The leader patted Yan Zheng on the shoulder again and led him back to the thatched house.

As soon as they sat down, several young girls brought food from six clay pots.

There are three kinds of meat, one type of beans, porridge, and two kinds of wild vegetables.

The leader smiled and made the gesture of eating, and he himself held a clay pot of porridge and drank it.

Yan Zheng also chose to drink porridge, if the clay pots of meat yesterday were like this, he was very suspicious of what he was hungry for, so he could eat it without noticing the taste.

The leader saw that he had a bad appetite and was slightly puzzled.

Yan Zheng didn't take a few sips, then got up and said that he was going out to do something.

Although he had seen a lot of problems in this tribe, he had to eat one bite at a time.

After teaching the wild man to take a hot bath, he had to speed up the popularization of some hygiene concepts.

At least they can't be allowed to at will.

After all, when he saw a savage girl boldly walking out of the thatched house, freely and happily between heaven and earth, and didn't wipe it after wiping, Yan Zheng felt that the whole person was not good.

Excrement is fertilizer if it's done right, and it's a breeding ground for bacteria if it's not done well.

A tribe with haphazard excrement is doomed to have a somewhat smaller lifespan.

And in the days when there were no chemical fertilizers, it was a bit of a waste to give excrement to wildflowers and weeds.

So Yan Zheng decided to dig a few toilets in the tribe.

And for the location of the toilet, it is also particular.

First of all, it must not be in the core area of the tribe, and secondly, it is better to be closer to the possible agricultural belt in the future.

After a little consideration, Yan Zheng arranged the location of the first toilet on the periphery of the tribe near the side of the river.

At the same time, he also plans to dig a toilet around the tribe.

As for one toilet per household, this goal is still somewhat long-term.

Under the command of Yan Zheng, several savages began to dig the pit.

Due to the lack of iron tools, the efficiency is low.

Fortunately, Yan Zheng's requirements are not high, just have a toilet here.

As long as the wild people in the future see that the dung can be used to make the crops grow better, they will naturally accept the toilet.

After they dug a pit, Yan Zheng felt that the depth was a little worse, and he was afraid that something would splash when he pooped in the future.

So he had the wild man cover the hole with thick wood, cover it with a layer of thatch, and cover it with earth.

Only one by one appropriately sized excretion openings are left.

The savages worked tirelessly, and Yan Zheng was also hungry and commanding.

By the time the toilet shed was erected, it was almost dusk.

Looking at the toilets that had taken a day to make, the leader naturally couldn't associate this shed with such a thing as.

He gestured and asked what the shed was for.

Yan Zheng walked in with a smile, peed, and then made a action.

The muscles on the leader's face froze for a moment, and several wild men who had been tired all day were also surprised, and even showed anger on their faces.

They worked hard all day, and the result was a place to.

Can't you just behind the house?

Yan Zheng saw that the leader didn't understand, so he pulled the leader to a thatched house.

There, he held back his nausea and found a piece of, which was already crawling with some kind of creature.

"This, harmful! If you live in a place where you have these, you will get sick like that old man! Yan Zheng gestured and explained to the leader.

After the leader understood this, he also thought about it.

He, who has been pooping casually for decades, is suddenly told that is harmful to the tribe, and it takes time to accept.

However, the leader's next move still put Yan Zheng at ease.

The leader summoned the clansmen, and I don't know if he gave an order not to at will, so many clansmen were full of incomprehension.

But the next actions of the clansmen almost made Yan Zheng vomit out all his bitter bile.

The clansmen began to clean up the feces in the tribe, and they didn't have a better cleaning tool, so they got started!
