Salt boiled in urine certainly doesn't taste as good as pure salt.

So the leader who learned the truth was silent, he couldn't imagine that there would be these things in the pee that he sped every day.

Seeing this, Yan Zheng chose to cook it himself and use salt to make a meat for these savages to see.

He found some animal oil in the thatched hut and used a stone knife to finely chop a piece of stewed meat.

After putting animal oil in the clay pot, put some salt in it, and when the salt and oil are combined, put the meat into the clay pot.

After stir-frying a few times, add a piece of leftover wild ginger, and the fragrance will spread in the thatched house.

The leader watched silently, his eyes falling on the particles from time to time. He's been stimulated more these days than he's been in decades.

When Yan Zheng finished frying this dish and invited him to taste it, he picked up a piece of meat, tangled it for a while, and then put it in his mouth.

After only one bite, the leader was stunned for a moment, and after a few more chews, he picked up a piece of meat with his hand and put it in his mouth.

After eating several pieces in a row, the leader seemed to come back to his senses, sat down silently on the side, and began to be silent again.

Yan Zheng didn't understand what the leader was wringing, so he put the target of feeding on the old man.

When the first piece of meat entered the old man's mouth, the old man's mouth couldn't stop, and there was greed in his eyes.

His mouth was full of oil, and his throat made a whining sound, but he was still longing for Yan Zheng to quickly stuff the meat into his mouth.

Judging by the desire to control himself, the leader is a hundred times stronger than this old man.

Maybe the leader knew it was coming from urine, so he had something he wanted to hold onto.

After eating it all, the old man's expression gradually became normal, and he lay with his eyes closed, as if he had been savoring.

"This thing, if you want it, you can find it!" Yan Zheng simply gestured with the leader.

The leader shook his head, he seemed to think more.

Yan Zheng didn't want to say anything more, he made these salts so that the people of this tribe could know that there was a taste called salt salt.

He took the salt and left the chief's thatched hut and went to the place where the young prisoner was being held.

The young captive was tied to the tribe's pyre at the moment, and after seeing Yan Zheng, he smiled reassuringly.

Yan Zheng gave him food for the past two days, and he could see that Yan Zheng saved his life.

And today, Yan Zheng is going to do something even more risky, he wants to release this teenager.

He had already observed the route, though the tribe had no real vigilance to speak of.

"You don't understand what I'm saying, but I hope God can bless you and understand me a little more."

Yan Zheng smiled bitterly and started to communicate body language again, and his body language has improved a lot these days.

He took a little salt and touched it on the boy's lips, waiting for the boy to look surprised and happy.

He poured the remaining salt into a clay cup, stuffed a burlap into it, and then gestured to the young man, "This, you, take it back, I will release you." ”

The young captive's face showed a look of horror, but he nodded anyway.

Yan Zheng drew two more circles on the ground, placing the pottery cup in one circle and a stone in the other.

After making an exchange motion, the young savage nodded, and stretched his neck, motioning for Yan Zheng to remove the bone ornament from his neck.

After Yan Zheng saw that he understood, he let out a long sigh.

After saving the teenager that day, he had this idea, and he felt that people had to understand that there was a possibility of exchange.

Once barter is formed, trade is formed.

The profits from trade will make it more expensive and difficult to start a war between tribes, because there is more to take into account when going to war again.

In the past, it may have been fought for a pig, but in the future it will have to be at least for a cow.

Yan Zheng gestured for a while, signaling to the young man that if he wanted this thing in the future, he could come over and change it.

Then, regardless of how much the boy understood, he untied the rope and motioned for him to follow him.

Almost without encountering any obstacles, Yan Zheng sent the boy away from the riverside of the tribe.

The boy also bowed gratefully before leaving, and then ran lightly into the woods.

Yan Zheng looked at the young man and felt that he was doing something very meaningful.

Later generations may record: political benevolence and virtue, the enemy will be released, the enemy will feel his kindness, and then the clan will return.

Of course, this is just his obscenity. There are more than a dozen words in the history books, and there may be many hardships and darkness behind them.

After doing this, Yan Zheng returned to his thatched hut.

Lan Ya was still dealing with the skin, and when she saw Yan Zheng returning, she immediately brought a glass of water.

Yan Zheng sat down peacefully and stretched out his big feet.

Lan Ya began to pinch it knowingly, and while pinching, she also accepted Yan Zheng's guidance.

Although this girl's strength is a little bigger, Yan Zheng is painful and happy.

After pinching it for a while, Yan Zheng's gaze fell on the skin again.

He got the salt, but he didn't expect that the yield of this boiling method would be so low.

And salt is not synthesized by the human body, it comes from ingestion.

Therefore, boiling salt with urine is just no way, and Yan Zheng can only hope that these savages can taste the taste of salt.

That would make it easier for him to convince these people to follow him in search of salt.

He thought about it in his mind, but in his heart he sighed, whether it is for a country or a tribe, it is born and will be there for a lifetime.

If this tribe had been born in a place facing the sea, he would not have been reduced to boiling urine and making salt.

It can only be said that natural geographical conditions are the eternal restricting factors for human development.

He looked at the leather that Lan Ya had treated, and his memory also came up about the processing technology of leather.

Although human beings first treated the skin with coarse salt, in fact, it was the nitrate salt that played a major role.

Now he doesn't know when he will be able to obtain salt in large quantities, so he has to try to make nitrate.

But nitrate is inedible, except for processing skins, I really don't know what this tribe can do with nitrate.

Among the soil methods he knows, the most productive is the stacking nitrate method, which can be refined by using the oven method.

This method requires the nitrate of soil to be mixed with the manure in proportion. Then put the mixture on dry and ventilated flat ground, as long as the thickness is kept at one to two feet to prevent it from getting wet by rain, and pile it up for about 20 days, you can get artificially cultivated nitrate.

Of course, you can also find nitrate directly on the toilet wall, or you can go to the nitrate hole.

However, the yield is not as good as the nitrate, and the more the nitrate is piled, the more trouble-free, because the nitrifying bacteria that play a role in it will be continuously optimized.

It's just that according to this method, he just finished cooking urine, and he has to play again.

In a tribe that doesn't pick on, collecting feces is definitely something that will be considered heretical.

And he had to get the soil first, in this tribe that just had a toilet, the soil in the roots of the old wall did not necessarily have much nitrate.

After thinking about it, Yan Zheng felt that it was necessary for him to look and see if there were any caves nearby.

He felt that since he had the conditions, he should get the nitrate out as soon as possible, after all, this is also a traditional Chinese medicine, and he can also add some charcoal powder to pretend to be a ghost.

If he finds sulfur, he can directly master chemical energy, and directly make the wild man kneel down and call Dad.

After Lan Ya finished pinching her feet, she carefully wiped the bone staff and skull in the room.

Yan Zheng didn't understand why she was so respectful to people.

Maybe it's because I've seen a lot since I was a child, so it's not strange.

"Lan Ya!"

"Father!"

Yan Zheng instructed her to put the bone staff and human head at the base of the wall and cover them with animal skins.

Lan Ya looked at Yan Zheng hesitantly after understanding.

Yan Zheng sighed, as soon as he opened his eyes in the past two days, he saw the skull, he was afraid that over time, he would not be surprised.

He himself got up and placed the bone staff and skull in the corner of the wall, covering them with animal skins.

One day, he will bury all the skulls of the tribe.
