Yan Zheng didn't understand why the leader and Wu were so enthusiastic about hatching eggs.

When he got up early in the morning and saw two haggard men with dark circles under his eyes, he was actually scared in his heart.

He thought to himself how to explain it to the two of them if it was yellow.

What's more, he was really afraid that the eggs would not hatch, but he boiled the old man away.

He hurriedly inspected the condition of the four eggs, turned them over, and sprinkled a little water to increase the humidity.

From the point of view of the feel temperature, this way of maintaining the temperature is still very effective.

After doing this, he went to the back of the house to inspect the transplanted Peilan, Xinyi, and Shiso.

It was found that the leaves showed no signs of hanging and wilting, indicating that there was a high probability of survival.

He was very satisfied with this, and when it was strong, he planned to pour some more manure water, anyway, the tribal toilet was already a little stocked.

Since the leader gave the order on the day of the fight, there have been quite a few clansmen who will go to the toilet.

However, most people are still accustomed to finding a place to solve problems in the world close to nature.

The only difference is that they no longer pull in front of the house and behind the house, but learn to find a place far away.

Of course, after not letting them in front of the house and behind the house, there will naturally be people pulling in the thatched house.

Yan Zheng has nothing to do about it, and the popularization of the concept of hygiene is really a process.

He went to the place where the pottery was made, and found that there were already a dozen or so industrious clansmen gathered here.

Maybe there was a witch's instructions, so they burned a batch of pottery according to Yan Zheng's method a few days ago.

With the addition of the end of the broken pottery, the success rate is much higher.

Yan Zheng looked at the clay embryos they had made and nodded with satisfaction.

And through body language, let them make more molds.

I believe that in a few months, these people's skills in making large pottery will be perfected.

And today, what he has to do requires a lot of large clay pots - he has to boil nitrate.

In one breath, he was about to take away all the finished clay jars, and had twenty young men gathered.

The principle of boiling nitrate is also very simple, that is, potassium nitrate is easily soluble in water, but as the temperature increases, the solubility rate will gradually decrease.

Taking advantage of this property, Yan Zheng asked the tribesmen to put the collected nitrate into a large clay jar and stir it constantly with wooden sticks.

If he is a little more demanding, he should actually use the method of nitrate leaching to get higher purity nitrate.

In short, it is to fill the nitrate with a large vat with a hole in the bottom, and pour it with hot water at about 75 degrees for the first time.

After pouring hot water, pour cold water again. You can get a solution with different concentrations, and then boil nitrate.

In the savage world, though, purity has no real meaning.

There are eight large clay jars, each filled with two baskets of soil, and three times as much water.

Stir until the mud and water are liquid, and then you can start to rest.

After standing still, the solution in this vat is transferred out for nitration.

Since the clansmen already had the experience of boiling urine, they thought that this was boiling salt again, and they all screamed.

Boiling these soil is much more comfortable than boiling urine.

When the first cylinder of solution crystallized in the heat, a cheer rang out.

This time, I brought back fifty-seven baskets of nitrate, which is about more than 1,000 catties, as long as I can boil out 100 catties of nitrate, it is enough for Yan Zhenghuo.

He took a look at the crystallization of the first pot and found that the quality of these nitrates was very good.

He asked his people to start stirring slowly to prevent the bottom of the vat from clumping.

When there were more and more crystals, he asked his people to fish out the crystals and put them on a linen cloth to wait for them to dry.

Seeing that a clansman dipped his finger in a little and intended to taste it, he immediately waved his hand to stop it.

This thing looks like salt, and it has a little salty taste, I'm afraid it tastes better than the salt boiled out of urine.

But these nitrifications can't be eaten, and Yan Zheng will not coax the clansmen in this kind of thing.

He wouldn't lie to them about what wasn't salt, even though he wasn't sure when he would find a reliable source of salt.

After stopping the clansmen, Yan Zheng handed over the work to the clansmen.

His gaze was on the slime that had been brought back with the nitrate.

The attached slime formed by these iron bacterial colonies must contain iron.

In the records of the soil law, there is a method of how to make a little iron from this kind of clay.

It's just that what Yan Zheng wants most is a magnet, but he has no way now, he knows some ways to magnetize iron, but it requires electric current and elements such as copper and nickel.

He planned to make the iron so that the people would recognize the form of the iron, and then let them pick up similar stones when they encountered them in the wild.

He had more people assembled, and he was going to do a preliminary job of the slime.

However, the clansman expressed his lack of manpower with a somewhat embarrassed expression, judging from his body movements. He expressed that the tribe's food reserves were insufficient, and most of the young men had to go out hunting.

This made Yan Zhenglao's face blush, and the responsibility for the lack of food reserves was almost all his.

He taught pottery, and as a result, ten young men now had to make pottery for the tribe.

He taught salt making, so the three laborers had to boil urine every day, and the freedom of the tribesmen to pee was greatly restricted.

He went on a quest, and as a result, the tribe sent out a lot of hides and dried meat.

What's more, for the sake of his exploration operation, these people did not go hunting for several days.

But Yan Zheng thinks that this is a good thing!

It's really a good thing!

Because of the previous tribe, there was no concept of insufficient manpower.

Before them, they were almost hunting, gathering, eating, sleeping, sacrificing, and communicating, and the labor productivity was very low.

And Yan Zheng has been in charge of at least boiling urine these days, and someone has to be responsible every day.

In the case of pottery, if there is no trade, it is likely that the work will end after the large pottery required by the tribe is made.

But boiling urine is different, they have to boil every day!

Isn't there a division of labor?

However, the problem of food is really a big problem.

Hunting is impossible to support too many skilled people, so it must be farmed, and salt must be found!

Yan Zheng made up his mind at the moment, in the spirit of doing more and doing more quickly, he decided to take the savages and reclaim the land as soon as possible!

If the young man goes hunting, let the women of the gatherer do it first!

One day, he will plant crops all over the mountains!

It just so happens that the solution left over from boiling nitrate is fertilizer.

Yan Zheng no longer mentioned dealing with the slime, and he led a few people to the reed field by the river.

He touched the reeds and felt that the humidity was a little high, but the top was dry.

He had dry firewood brought, made a path through the reeds, piled a large pile of firewood in the middle, and instructed them to make a few firebreaks.

Then, in the astonished eyes of his clansmen, he lit a fire himself.

The fire roared, and the reeds, which had been somewhat wet, were roasted and caught on fire, and after spreading, the other reeds were dried.

In this way, the wind fueled the fire, and the fire fueled the wind, and a reed, about 1,500 acres, was reduced in the fire at a speed visible to the naked eye.

The smoke even covered the sky and the sun, reaching into the sky.

The clansmen didn't understand why Yan Zheng wanted to destroy this reed, but looking at the raging fire, they couldn't help but be afraid.

It burned for nearly an hour, and it was not until the fire hit the firebreak that it died out that the tribesmen breathed a sigh of relief.

Looking at it again, there were still some surviving charred reeds left on the dark ground, and the remnants of sparks flashed and flickered.

Yan Zheng looked devastated and devastated, but his heart was extremely heroic, he felt that from the moment the human race was born, it was born for destruction.

Our construction is based on destruction, we have destroyed everything that was originally on the earth, and we have built everything that belongs to us human beings.
