For the second brother of King Kong to use the gambling curse to swear this trick, it really worked very well, the primitive people's awe of the gods, so that the fish's doubts were completely eliminated, and after weighing the pros and cons, he was immediately freed from the dilemma.

Although there are only 20 male warriors in his tribe now, he has to take out 5 warriors to exchange at once, which is equivalent to reducing his strength by 1/4, but as long as these children are saved.

Let them survive this winter, and in less than two years, the River Tribe will be able to reappear twenty or thirty warriors, so they immediately agreed to the proposal.

But he has never heard a sentence: what is bought is never sold! Wang Tianzhi was in the entire River tribe, this time even God helped, how could he give up this God-given opportunity.

Yu, the leader of the River Tribe, immediately decided to exchange 5 adult warriors for food with the Tianlong Tribe, and those half-grown children also sent 20 people to the Tianlong Tribe.

He selected 5 thin adult warriors as the object of exchange with the Tianlong tribe, and Wang Tian didn't care, you are just thin, live in the Tianlong tribe for a few months, and keep you strong.

In fact, the people of the entire River tribe are relatively thin, and these 5 people are just a few telephone poles picked out by the thin people.

Wang Tian glanced at the children in the tribe and found that there were as many as 50, and there were more than 20 pairs of spouses in the River tribe.

Wang Tian estimated that this was related to the cave they were in, which was a cave of malachite, malachite contains natural copper, which can activate the natural antioxidant enzymes in the skin, so that the antioxidant enzymes in the skin can play the maximum role and achieve the purpose of antioxidant.

This is also the reason why people in the River tribe look relatively white, wearing malachite jewelry can slow down the formation of the stratum corneum of the skin, so as to achieve the effect of delicate and soft skin.

In addition, malachite also has the effect of disinfection and regeneration, desaprophylaxis, and the ancient Egyptians once ground malachite into powder and applied it to festering wounds to treat external injuries.

French scientists have extracted a natural active substance in malachite, which can enhance the activity of cells, and the people of the River tribe live in such caves every day, which is estimated to be of great help to the "little tadpoles".

That's why the people of this tribe are so capable, and as for these people who are so thin, in addition to the food, it should also have something to do with these heavy metals around the cave.

Of course, these are Wang Tian's own speculations, whether there is a scientific basis or not, he himself is not clear, the next is the conditions of exchange, this is naturally the second brother to talk to them, there is no need for Wang Tian to care.

Taking advantage of this skill, Wang Tian carefully observed the cave of the River Tribe, he felt that the heavens were really magical, the cave of the Tianlong tribe was a natural salt mine, and the cave of the River tribe was a natural copper mine.

Moreover, through his observation, there was pure elemental copper in the cave, and he took advantage of the fact that he used his saber to cut some of the foam with his hand, and found that it was 100% metal.

And the wound that was cut out, the golden light is like gold, which is completely different from the copper in Wang Tian's impression, it seems that he has been deviated by the pictures of the media network, and when people in later generations mention copper, the first thing that comes to mind is the appearance of bronze.

In fact, the pure copper that has just been produced is really not much different from gold, the same golden brilliance is brilliant and dazzling.

God was still very generous to him, two caves, a salt mine and a copper mine, and both had 100% pure single crystal salts and elemental copper.

He was now looking forward to visiting the other two tribes, wondering what other surprises were waiting for him in these two tribes? Will it be iron? Or the tin and lead necessary for the refining of bronze alloys...

It is impossible to estimate lead, can this person live in a lead mine?

Just when Wang Tian was thinking about this, the second brother of King Kong came over and said that the price had been negotiated, and the five warriors each used 3 times the food that the five people could carry as compensation, or "dowry".

That is, 15 adults can carry food as a dowry, except for the Tianlong tribe, the other primitive tribes do not have the concept of weight, so they can only use this primitive measurement method.

As for this child, it can only be the maximum weight that a child can carry, so in order to be able to exchange more food, the River Tribe will inevitably choose to send a larger child to the Tianlong Tribe.

Wang Tian looked at the second brother of King Kong, but he didn't expect this rough man to have such a scheming, and Zhang Fei could use it, which was the blessing of the Tianlong tribe.

In later generations, it would be very good to be able to easily carry 100 catties of cement (referring to the back instead of picking), and these thin people of the River tribe, even if they were fierce primitive people, Wang Tian estimated that they would only be 200 catties on the top.

Moreover, it is a concept to be able to carry it, and whether there is something to pack is another concept, the Tianlong tribe can generously provide them with a basket, but a basket of fish, there is no 50 catties to die, even if it is a little more generous, the largest basket of the Tianlong tribe will be measured, and the top of the sky is 100 catties.

Wang Tian clearly remembers that the weight weighed in the first fishing was about 70 catties per basket on average, although it was only flat, but even if it was all full, it was 100 catties.

That is to say, the tribe can use a maximum of 2,000 catties of fish to exchange for 5 adult laborers and 20 and a half children.

In this regard, Wang Tian "generously" said that the tribe can use salted fish as exchange food, and his statement immediately attracted the belly slander of the giant salamander: "In addition to salted fish, are there any fish without salt in the tribe!" ”

In fact, the fish promised to the River Tribe can be caught on the spot at the door of the River Tribe's cave now, but how could the shrewd and cunning Son of Heaven reveal this secret to them!

It seems that the people of the River tribe are destined to make an extra trip to their own tribe to pull fish, not to mention the time and effort, with such a trip back and forth, the people of the River tribe will not have time to drive away the monsters they are talking about!

Of course, the giant salamander is just too much mental activity, in current terms, that is, this guy will come to trouble, which does not mean that he is disrespectful to the Son of Heaven.

On the contrary, since the Son of Heaven helped him hide the fact that he escaped by urine because he was afraid of death, and the Son of Heaven also used his own blood to help him detoxify the monster, causing the Son of Heaven to be in a coma for a day and two nights, he has become a die-hard fan of Wang Tian.

The reason why he made such a meticulous observation was only due to the worship of the Son of Heaven, and Wang Tian knew more or less about this guy's psychological activities, after all, he had the artifact of stream of consciousness in his hand.

For the careful observation of the giant salamander, Wang Tian is appreciative, the giant salamander has a strong sense of direction, and the ability to recognize the way is first-class in this era, don't underestimate this ability, there are many people in the tribe now, and the southeast and northwest are still not clear.

With this ability, Wang Tian planned to hand over the work of trading with other tribes and communicating with other tribes to the giant salamander in the future.

In the future, the giant salamander will be equivalent to the head of the trade department of the Tianlong tribe, and the madman next to the giant salamander, this tenacious guy, is the captain of his bodyguard team in the trade department.

The madman's bow and arrow skills have become more and more rebellious, and even Wang Tian has to bow to the wind, he can already hit the heart in eight or nine out of 10 shots from 50 paces away.

Wang Tian specially customized a bow and arrow for him, and only the leader and the second brother of the entire tribe could pull it, but if he wanted to shoot and ensure accuracy, he couldn't do it.

Bow and arrow as a long-range weapon, used to protect the trade team such a small number of people, is really suitable, with this Wen and a military general, if the wild horses on the grassland are tamed, then although the world is big, with the skills of these two people, you can get anywhere!

The giant salamander was analyzing the psychology of the Son of Heaven, but Wang Tian was arranging his future, but the leader of the River tribe obviously did not understand what salt was.

After solving the problem of food, the leader of the River Tribe, Yu, had just discovered that the outfit of the Celestial Dragon Tribe in front of him was significantly different from the last time they met.

The fur on everyone's body is so fitting, as if the animal skin grows according to the human body, and the animal skin used to wrap the feet is also so obedient.

And the weapons they held were also very strange, except for the spear, everyone was holding a piece of bamboo with strings, and the two ends of the bamboo piece were connected to the wood, and it seemed to be naturally connected, and there was no trace of the connection at all...
