On the morning of the second day, Xia Tuo left the tribe with the deer, carrying on his back a rattan basket woven with vines, in which were placed the skins of the animals to be exchanged for salt.

In the past, every time he went to the Lu tribe to exchange salt, he would consume the resources such as animal skins stored in the tribe.

The deer followed behind Xia Tuo, and the rattan basket on his back contained the skin and scale armor of the black wolf, which was the black wolf he hunted yesterday, and it also exuded a strong blood qi.

"Patriarch, cross that Niutou Mountain and enter a valley to the Lu tribe. ”

Lu had followed Hong to the Lu tribe to exchange salt, which was also the reason why Xia Tuo took him out.

The Lu tribe is in the valley under Niutou Mountain, Xia Tuo speculated that there should be a salt mine in the valley, but he didn't know how pure the salt was, but the Lu tribe did have a master, and he actually mixed salt into the gravel to trade.

After the two of them climbed down Niutou Mountain without danger, they were blocked at the mouth of the valley.

Shout!

An arrow feather shot out of the dense forest and pierced not far from Xia Tuo's feet.

"Arrows. ”

At this moment, Xia Tuo's eyes were straight, there must be arrows and bows.

At Xia Tuo's signal, Lu stepped forward and shouted loudly: "We are from the Xia tribe, come to exchange for salt." ”

Not far away, a huge tree leaning against the mountain wall, a sound sounded, the branches on the branches of the giant tree were entwined into a huge bird's nest, and the two figures were stained with a lot of bird feathers, lying in the bird's nest and looking at Xia Tuo and the two.

"Xia tribe?"

Tu tilted his head and glanced at Bai beside him, and asked, "I haven't heard of it." ”

"We came from that valley outside the nine mountains, and I was here last time. ”

"Is that him?"

Shiro squinted at the deer.

"You know him. ”

Bai shook his head and said, "I don't know." ”

There are many tribes in the Wangu Mountains who have come to their Lu tribe to exchange salt, and he can recognize everything.

At Xia Tuo's signal, the deer then shouted, "We brought the scale armor of the black wolf of the Split Stone Realm. ”

Xia Tuo's eyes looked at the huge bird's nest on the tree, and he really thought he was a bird with a hair on his head.

Soon, the two guys in the bird's nest tumbled down from the branches, and taking advantage of this opportunity, Xia Tuo walked forward quickly, grabbed the arrow feathers tied on the ground, and threw them into the forest behind him.

His gaze was fixed on the two men who had come as they came, with simple animal skin armor on their bodies, one of whom was holding a large jet-black bow in his hand.

Sure enough, the Lu tribe had a bow.

Missed the system again.

"In Xiaxia, the tribal leader came to your department to exchange salt. ”

"Your name is down?"

"We are the Lu tribe, not the noble tribe. ”

“......”

Looking at the two guys with bird feathers on their heads, Xia Tuo directly closed himself.

"Hehe, the bow is good. ”

Looking at the guy with the bow, he suddenly stepped forward and said with envy in his eyes.

"I am the most powerful archer of the Lu tribe. ”

The guy with the bow was complimented by Xia Tuo, and suddenly got up and forgot to even look for the arrow to shoot.

"I'm white, he's Tu, you have to change the salt, I'll tell the leader later. ”

After speaking, Bai took the bow and slapped Tu next to him, and Tu ran towards the valley with a reluctant face.

"Being able to hold a bow makes you the most powerful warrior in the tribe. ”

Looking at the wary look in his white eyes, Xia Tuo dispelled the urge to look at the bow in his hand.

After a while, Tu ran back from the valley and shouted, "The leader let you into the tribe." ”

Under Tu's guidance, Xia Tuo and Lu entered the Lu tribe in the valley, and like their tribe, the Lu tribe also relied on the caves in the valley to live, and there was a defensive wall formed by huge stones at the mouth of the valley.

Tribal warriors were stationed on the defensive wall, and beyond that, Tu and Bai were hiding in the bird's nest as a warning.

"It's you who want to change the salt. ”

As soon as he stepped into the tribe, Xia Tuo walked over to a strong man, with a white bone beast head on his head, two horns, hanging all kinds of scattered small animal bones, and the animal skin clothes on his body were shiny.

The strong man was two heads taller than Xia Tuo, and there was a faint dark cyan totem pattern flickering around his neck, and a strong blood qi rushed towards him.

"Something left. ”

Without waiting for Xia Tuo to speak, the strong man waved his hand, and someone behind him stepped forward and placed two stone jars in front of Xia Tuo.

The strong man's words directly made him feel like he had entered a wolf's den, and it was really a seller's market, and he could do it.

"Okay. ”

Xia Tuo grabbed the deer, took off the animal skin from the rattan basket behind him, put the two stone jars in it, pulled the deer and turned around and left.

After Xia Tuo turned around, the black wolf scale armor they brought was immediately picked up by an old clansman of the Lu tribe and carefully examined it.

"Chief, there are several large holes in this wolf's skin, which should have been pierced by stone tools, and the wolf's bones on his back are shattered. ”

Even if the wolf skin was broken, there was still satisfaction in the old man's eyes.

"It seems that this Xia tribe really had a lot of luck and hunted a black wolf. ”

The leader of the Lu tribe glanced at the wolf skin, turned around and walked towards the cave, and commanded, "Make this wolf skin Lu out and see if you can make a pair of armor." ”

"Chief, will the Xia tribe ......?"

The leader turned around and glared, "Unless they don't eat salt." ”

......

"Patriarch, they've gone too far. ”

Leaving the Lu tribe, Lu shouted angrily.

This time, although they were given two jars of salt, they brought the scales and fur of the beasts of the Cracked Stone Realm.

Xia Tuo was also very angry, but he didn't show it in the Lu tribe, who let the family monopolize the salt, and he really had to pretend to be a grandson before there was no other channel.

Although he had only been in the Lu tribe for a short time, he observed that the strength of the Lu tribe far surpassed theirs, and there were no less than ten totem warriors alone.

It seems that this salt is really profitable, relying on this hand-made salt method, the Lu tribe is really nourishing, and people are so strong.

Today's treatment of them is probably not exceptional.

After leaving the Lu tribe, Xia Tuo searched for it in the forest, and he found the arrow feather that he threw into the forest.

About three feet long, the arrowhead was ground of bone, with a hardwood in the middle, some feathers glued to the tail end, and a kind of dried gelatin on it.

Obviously, the Lu tribe already knew how to refine or use this glue to make bows and arrows, and he had let the tribe polish stone spears before, not because there were no bows and arrows.

"Let's go. ”

Placing the arrow feathers in the rattan basket, Xia Tuo returned to the tribe with the deer.

Naturally, this encounter caused the tribesmen to be very angry, Xia Tuo pressed down one by one, it is not clear how many catties and taels he has, saying that it sounds good is a tribe, and if it is not good, it is a gathering point for refugees, and he wants to have a bullshit face, and when he becomes strong in the future, the face will naturally come.

Of course, many people in the tribe don't understand his thoughts, and they can't wait to copy the guy and have to fight, but fortunately, if they don't understand, they don't understand, but they obey Xia Tuo's orders.

......

At night, bonfires burn and illuminate the cave.

Xia Tuo handed the arrow in his hand to the reined elder below and said, "Can we make this kind of arrow?" ”

Elder Reins didn't speak, and handed the arrow to Hong next to him, and after a while, the arrow returned to Xia Tuo's hand again.

"The patriarch's bow can be made with animal bones, but you need to choose animal bones with curved arcs, and the bowstring has animal tendons, but we can't make this kind of arrow, and this kind of colloidal glue that adheres to feathers is unknown. ”

"This transparent glue will find a way to make the bow first. ”

Handed over the task of making a bow to Elder Reins, Xia Tuo opened the soil salt exchanged from the Lu tribe, and the Lu tribe's trade in soil mixed with salt was really prosperous.

A jar of salt and half a jar of soil, Xia Tuo took out a fist-sized stone from the stone jar, the Lu tribe is a bit excessive, the largest salt grain is only the size of a finger, but the stone is a little big.

Not only that, but the two stone jars in front of him were one large and one small, the largest one was one and a half feet high, and the diameter was about one foot, and the stone walls were thick enough to block arrows.

The smaller one was a foot high, and according to the rules, each of these two jars was a pound of salt, which was even counting the stone jars.

But this is also something that can't be helped, who let the family have their own hands.

Under the light of the fire, the salt grains glowed blue and exuded a faint astringency.

Grabbing the salt grains, Xia Tuo's expression was a little hideous under the firelight, and he said fiercely: "Lao Tzu wants to substitute salt for himself." ”

Soon after the order was given, the wind came with a woman from the tribe named Mu, and the two of them came with several stone jars and a stone with a depression in the middle, and it was dark under the stone, which had obviously burned for a long time.

After picking out the sand grains in the jar, he grabbed two handfuls of salt grains and put them in one of the stone jars, added well water and stirred, and all the spiritual salt grains melted.

As expected, the salt water was cloudy and covered with cyan flocculents.

Let the wood pick out the flocculent in the water, pour it into another stone jar, filter out the sand grains in it, and after doing this a few times, pour the brine into the groove in the stone.

While the wood was filtering the salt water, Xia Tuo built a platform on the bonfire with stones and erected the stones containing the salt water.

He used to live in a world where he was not a scholar, and he failed mathematics, physics and chemistry, so he could only remember such things, and then he could only look at the will of God.

The flames scorched the stone, and soon the water in the groove was boiled, and at Xia Tuo's signal, the wood was still adding firewood below.

Soon, on the surface of the groove, a thin layer of whitening and temporary delicacy emerged.

It's done!

Xia Tuo stretched out his head to look at the grooves in the stone, although the white temporaries still had mottled cyan, it was much better than the salt grains at the beginning.

After a long time, the water in the stone was evaporated, and a layer of fine salt crystals adhered to the surface of the groove, Xia Tuo reached out and dipped it a little, and licked it with his tongue.

Well.

Salty!

Although there is still a bitter taste, it also shows that his wild jungle version of the distilled salt method works, but unfortunately there is no iron pot.

But it's all mixed up like this, what's not to be satisfied with.

The salt in the stone groove was collected, and there was only a small handful, but it was white, and it was many times better than the salt grains in the stone jar.

It was only at this moment that the wind reacted from its sluggishness and hurriedly ran out.
