After calming down, Su Yang found that it was not so simple, copper and bronze are two concepts, copper refers to pure copper and red copper; Bronze is already an alloy, an alloy with tin or lead. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

If it is only pure copper, the texture is soft, and it is used to make cables, which is leveraged and has good conductivity. It is also possible to make various tools by hammering, but it is not practical, it is easy to be blunt, and it will oxidize when exposed to the air for a long time, so it cannot be used as a weapon or agricultural tool.

In the period when primitive people used pure copper, it is also known as the red copper age, the era of gold and stone, and the era of ruin copper.

But this copper is already very troublesome, natural copper is limited, and every piece that can be found is consuming character. The melting point of copper is close to the temperature of 1,100 and needs to be maintained for a long time, and the process of purification is not easy, there are several steps in the middle, and the need for combustion, the design and construction of copper furnaces and so on.

In the end, a large amount of copper is obtained, and it is necessary to smelt tin or lead, mix it proportionally, and after obtaining the bronze, it is necessary to model and infuse the embryo of the object, which is forged and formed, polished and opened.

At this time, Su Yang himself deduced that it should be in the late Mesolithic period, that is, the transition stage from the Paleolithic to the Neolithic. The Neolithic Age was marked by the polishing of more sophisticated stone tools, the tribes had planting, animal husbandry, pottery, textiles, etc., and primitive people came out of the caves to form villages.

At present, some super large tribal alliances, such as the Dongyi Long clan, are already moving towards the Neolithic Age, but the Jiuli tribal alliance can only be regarded as semi-developed, or the Mesolithic Age.

After entering the Neolithic Age, it also means that the matrilineal clan has reached its peak, and the prosperity must decline, and in the late Neolithic period, the emergence and use of red copper also marked the rise of the paternal line, and it is unknown how many years from modern times.

In other words, if he makes red copper now, it will span a Neolithic period of thousands of years, but it may not be able to make the paternal line rise on a large scale. Since the existence of primitive man, I am afraid that it has always been the matriarchal king, and its women may be inferior to men for hundreds of thousands of years, and women's rule for so many thousands of years can be overthrown just by the appearance of red copper.

In his understanding, there is a paternal line first and then a red copper, the paternal line does not rely on the red copper to overthrow the maternal line, the root is still in eating, who can feed more people, who is the king, natural transition!

As for Su Yang himself, as long as he can be called emperor when he is alive, it doesn't matter whether other tribes are matrilineal or patrilineal. Maybe he will become Wu Zetian in the primitive matrilineal clan period? A unique patrilineal king!

Okay, wipe the corners of your mouth, it's time for Su Tianzi to wake up from his daydream, if you want a copper mine, you must first kill the Xiyi people, otherwise it won't work out in the end.

His previous plan was about to change, he had originally wanted to use clay to persuade the Salt Clan to join the Twilight Alliance in the war, but now there was no room for anyone else to be contaminated here, and it was up to him to do so.

"Bearded, remember what I told you earlier?"

"Yes." The bearded man nodded, and this time he didn't look at him.

"Very well, you go to the people of Xiyi in front now, and I will have someone follow you. If the Heyi guards are willing to take you in, then do as I say. If they want to kill you, run and we'll pick you up. He felt that this arrangement was still very appropriate, and the Xiyi people did not kill people when they saw them, and besides, the bearded man was a true performance.

This time is also just right, the Xiyi people will not send troops in the evening, and if the Xiyi people are really robbing the Youyan clan, it is very likely that they will also send people, so that there is a time difference, stepping on the time point, and letting the Xiyi warriors be divided into two, which is more beneficial to them.

Immediately he gave orders to the bearded man, and let him go on his way, and he took thirty men with him, and the rest of the warriors continued to guard here, and if he found a small group of Xiyi people, he would kill them as he had done before.

Because Chun has already explored the road, they walked very fast, and it took ten minutes to enter the mountain range, sure enough, there are stones everywhere here, but it is not that you can bend down to pick up cuprite, malachite, not to mention natural copper, but it is indeed a treasure land, just the surface of the ore, can make him do a lot, build weapons to improve combat effectiveness.

Most of the leaves of the trees here are red, and he doesn't know what kind of tree it is, but the scenery is very good, it looks like a mountain forest with flames, and the further you go, the more scarce the trees become, which is probably related to the distribution of ores.

The bearded man went out alone, and as he walked away, he saw some of the Xiyi people appear, talk to the bearded man, and finally take him away.

"It's done, let's withdraw too, don't leave a trace."

Their task is still very heavy, and they need to rush to arrange it overnight, but sure enough, it is more leisurely to stay in the tribe, and they can't stop after they come out.

Don't say anything, run, you'll be a running man in the future. They didn't run blindly, but slowly and rhythmically with their fists clenched.

When they arrived at the place where the traces of the fire were found before, ten people were left, Chun and Feng Bo were left, and as expected, this was the dividing junction. He didn't send anyone to check on the situation on the Yan side, because he was not familiar with the terrain there, and he didn't have time to do it.

"You spend the night here, be careful, and run back as soon as you find the Xiyi, it's best to have a rough estimate of the number of people, and we'll intercept the enemy halfway."

Because the wall of the garrison has not yet been completed, I am afraid that it will be difficult to defend, and this time it is to kill more Xiyi people, so it is inevitable to engage in close combat.

Continuing on the road, after about two hours, thirty more people were left, and then Su Yang returned to the tribe with twenty people, which was already the middle of the moon.

During the day, the rain was affected, and instead of being completed, the wall was washed away and needed to be repaired. It's not the best choice to start a war at this point in time, but now you can't regret it.

When he arrived at the tribe he didn't say anything, and he didn't let the Prabhu say anything, and he simply ate some food and went to sleep, but he was woken up before dawn.

"Go and wake everyone up, the non-combatants should be evacuated to the mountains and forests, the clay pots should not be moved, and only light supplies should be taken." He is going to clear the field, prepare for the worst, and if he feels invincible in numbers, then run away.

Although these auxiliary personnel can also take up arms to participate in the battle at a critical moment, it is not the time to fight to the death, and he will not agree to exchange a few people for a Xiyi person, let alone do it.

After everyone arrived, he briefly talked about the situation of the Xiyi people, and asked the elders to retreat with nearly two hundred people, and they could enter the mountains and forests in about an hour, and after entering, there was a piece of territory from the Xiong clan.

At that time, regardless of victory or defeat, someone will be sent to inform you, and the number of people left to participate in the battle is a total of two hundred, as long as the Xiyi do not exceed this number, then they can all fight, and now it depends on whether the bearded side has played a role.
