In the dark night, there was no other light in the River tribe except for a bonfire, and the air was filled with a charming atmosphere, Wang Tian looked at the women of the River tribe, surrounding the warriors of his tribe, all of them were eager to try.

And the warriors of their own tribe seem to be suppressing the little thoughts in their hearts, and under the strict orders of the Son of Heaven, no one dares to take a step beyond the thunder pool.

The thick drumming of the two weddings still seems to echo in everyone's ears, which is an order and a spur.

The people in the cave seemed to be itching one by one, including Wang Tian, but everyone thought differently, in order to prevent the people of the River tribe from misunderstanding, the second brother explained why he didn't make villains according to the tradition.

And welcome the people of the River tribe to come to the Tianlong tribe to participate in the party after the beginning of spring next year, but at the same time, it also shows that their tribe only hosts, and does not participate.

After Yu understood that this was the request of the Son of Heaven, he was puzzled again, knowing that this was a tradition, a matter recognized by the surrounding tribes, and this way of population reproduction was indeed advanced in this era, and he did not understand why the Son of Heaven of this tribe did not approve of this.

Wang Tian didn't sleep at this time, he was holding a bamboo sword, concentrating on dealing with a piece of elemental copper, you must know that this is a piece of pure copper, after cutting it off, it can be directly smelted into copper water.

There was no reason to return empty-handed after entering Baoshan, but Wang Tian had a sneaky feeling, an experience he had never had before.

How much can be deducted tonight, early tomorrow morning, after the people of the Tonghe tribe have said, Wang Tian will mine with everyone for half a day, and bring as much copper ore back to the tribe as possible.

Will return tomorrow afternoon, Wang Tian is still not very worried about the safety of the tribe, what kind of reaction will the Niu clan make after suffering losses one after another?

When he went out this time, Wang Tian had explained to the leader, and tried not to have a conflict with the Youniu clan, the cattle in their hands were too important to the Tianlong tribe, if he could, Wang Tian hoped to obtain it in a peaceful way.

Since copper has been discovered this time, Wang Tian does not plan to continue to explore, he just hopes that tomorrow he will find the associated mineral of tin in the process of mining malachite.

Later generations of knowledge made him understand that it was normal for these two minerals to accompany each other, and perhaps it was for this reason that the birth of bronze was possible.

Wang Tian was thinking that maybe people in history didn't know that copper and tin could be put together to get harder and more durable bronzes, but they were only accidentally discovered in the process of casting, because these two substances were accompanied by each other.

In fact, he used a bamboo sword to dig the cave walls of the River tribe, which had long been clearly seen by others, but the people of the River tribe thought it was just a child's game, so they didn't pay attention to it.

After Wang Tian found out about this situation, he was even happier when he pried the corners of other people's walls, of course, he was specially looking for a place to dig pure copper after choosing.

Wang Tian couldn't understand a little, the rock salt ore of the Tianlong tribe looked like fragile white stones, and it was reasonable to say that they were not noticed by everyone, and for these glittering "stones", they didn't even attract the attention of the river tribe, which made him a little puzzled.

After he had withheld the third piece of pure copper, in the cave that was not well lit, these were all the results of his sneaky observation during the day and the location of the note.

It is impossible to find pure natural copper again in the now dim cave, and the total weight of these three pieces of pure copper is estimated to be more than sixty catties.

It seems that tomorrow I will take some malachite with me, and forget it, as long as I get enough malachite raw materials for experiments, the main focus is still on finding tin ore, after all, it is only pure copper, and the use is very limited.

With these three pieces of sixty or seventy catties of natural pure copper, a lot of things have been made, and now the most important thing is to find tin, and through experiments to determine the method of refining copper and the proportion of copper tin smelting into bronze alloy.

He put two of the pure copper pieces into the back basket, then picked up a lighter one and found the leader of the River tribe, Fish, and said, "Boss Fish, this stone in your cave is so beautiful, I dug three pieces, can you give them to me?" ”

The giant salamander has never seen such a brazen person now, you dug it all up, and put it directly into the back basket, but now you have a tone of discussing with others, can people refuse?

The giant salamander knows that Wang Tian is not an ordinary child, and the things that can attract his attention must be good things, and the Son of Heaven does not have a hobby of playing with urine and mud.

Now that the Son of Heaven is interested in a few stones, it means that these stones are good things, because the Son of Heaven is now smiling so much that he can't see his teeth, and the harvest that can make the Son of Heaven so happy, everyone can't imagine what these golden stones do.

For Wang Tian's statement, who can refuse a child's request, it is only three golden stones, not to mention that the Son of Heaven also gave so many pottery to his tribe, these things are extremely precious in the eyes of everyone in the River tribe.

Then Wang Tian took the opportunity to ask to collect some of these beautiful malachites back to the tribe tomorrow, saying that he would also make a necklace, and then he picked up the back basket and picked up all the malachite that had just been dropped from digging pure copper into the back basket.

For Wang Tian's request, the leader of the River Tribe, Yu, was not surprised at all, children like these strange things, this is too normal.

However, on the second day, he discovered the abnormality, because the people of the Tianlong tribe collected malachite as if they were collecting food, no matter how big or small, whether it was beautiful or not, as long as it was a stone, they would pick it up.

Now, of course, it is impossible for the people of the Tenryu Department to dig in other people's caves, but they choose a relatively gentle rock wall and dig it.

Malachite is, after all, ore, and the tools they brought such as hand plows and stone hoes were not easy to use when mining, but were the most primitive spears and sticks.

The second brother of King Kong took the back of a metal axe and struck a hammer in the east and a hammer in the west on the rock wall covered with malachite, until the rock wall cracked out of the cracks.

Then the Tianlong tribesmen added wooden sticks into the cracks to pry, and continued to beat the ground with stone hammers on the side, and the two ways worked together to speed up the loosening of the ore.

Wang Tian was in the cave at this time, continuing to look for traces of pure copper and tin, but unfortunately two more pieces of pure copper were found, but the silver tin was never found.

Wang Tian did not give up, and after not seeing any traces of pure copper, he took his second brother around the mountain on the other side of the cave of the River tribe and continued to beat.

But in half a day, in addition to harvesting some malachite, nothing else was found, after this half a day's work, the Tianlong tribe harvested a total of about 100 catties of pure copper, nearly 2,000 catties of malachite.

After lunch at noon, Wang Tian was about to return to the tribe, and at this time, the originally cloudy sky turned into a gray patch, looking like it was going to rain.

The temperature in the air also seemed to have dropped a lot, seeing such a situation, the second brother of King Kong was worried that it would rain or even snow soon, and he also urged everyone in the River tribe to prepare to set off.

The malachite collected in the morning had been loaded on two bamboo rafts, and in addition to the five warriors and 20 half-grown children who were used for the exchange, there were 20 other adults who went with them.

These 20 adults are half male and half female, so that the River tribe has 25 adults at once, which has accounted for more than half of all their adults.

After everything was ready, a team of nearly 60 people in total began to set off, with two bamboo rafts each from the Tianlong tribe and the river tribe, and the river tribe's bamboo rafts were mainly pulling children.

In order to speed up the advance, Wang Tian asked five warriors of the Hehe tribe, who were already counted as the Tianlong tribe, to come to the bamboo raft of his own tribe, so that the six warriors rowed together, three on the left and right.

At the stern of the bamboo raft, there are 2~3 warriors holding the penny, and begin to go up the river along the long water, although the bamboo raft of the Tianlong tribe is more than 1000 pounds, but because the water flow of the long water is stable, although it is countercurrent, but the 6 oars are danced fast by the soldiers, plus the borrowing of the bamboo artemisia at the stern, the speed of travel is not slow at all.
