Seeing that the great Vulcan took this matter so seriously, Ape One couldn't help but shake his head, and quickly told everything he knew.

For a long time, Chen Xu lifted the red copper knife in his hand, and the light in his eyes gradually flashed, but he didn't expect this red copper knife to come like this, so it seemed that there was no need to change his next plan.

According to Ape One, the bronze knife was discovered by accident in the soil at the bottom of the pit when he was cleaning the battlefield for the last time, and he just thought it was an ordinary stone tool and did not pay much attention to it.

However, in the activity of cutting down trees after the return, the sharpness of the red copper knife was fully revealed, which was many times better than the stone tools used by other ape-men, and its cutting efficiency was so high that it exceeded the sum of several ape-men.

When they returned in the evening, all the apes talked about it, and after the ape-man No. 1 showed the red copper knife, it caused an uproar among the apes and alarmed Chen Xu, and things were roughly like this.

According to Ape Man No. 1, the apes of the Black Rock tribe seemed to know this red copper knife, and it was because of this that they made a loud noise.

"Could it be that this red copper knife is something from the Black Rock Tribe? Trap, trap!"

After pondering for a while, Chen Xu ordered Ape Man No. 1 to leave and find the Black Rock Witch Doctor, who had something to inquire about.

After a while, the Black Rock Witch Doctor stepped into the range of the ring of fire with a puzzled expression, and as soon as his eyes saw the red copper knife, he couldn't turn at that time, obviously he really knew this thing.

Waving his hand to signal Ape Man One to retreat first, Chen Xu woke up the Black Rock Witch Doctor from his daze and began to ask about the Red Bronze Knife.

Later, the Black Rock Witch Doctor told him what he knew, and as a result, as Chen Xu expected, this red copper knife was the thing of the Black Rock Tribe, and it was originally the personal weapon of the Black Rock Leader.

According to the Black Rock Witch Doctor, the possession of the Black Rock Chieftain owes much to this bronze sword, which in the Black Rock Chieftain's narrative is a heaven-sent weapon with endless divine might.

Before the death of the leader of Black Rock, the Black Rock Witch Doctor thought that this weapon had been lost in the jungle, but he didn't expect it to appear again, which really surprised him very much.

Letting the Black Rock Witch Doctor retreat, Chen Xu stroked the red copper knife in his hand, and he was most sure in his heart that this red copper knife should come from somewhere near the Black Rock tribe.

In that place, there was a rich open-pit copper mine, and the leader of the Black Rock found this miraculous red copper knife by some coincidence, and chopped it down with stone tools to intimidate the entire tribe, and truly achieved the absolute dominance of the tribe.

"It seems that the strategy for the Black Rock tribe is about to be put on the agenda, but I didn't expect that there is a rich copper mine there, it's really unimaginable, just with copper ore, it's just that you just have copper ore, if you want to refine copper, there is one thing that is necessary, that is, the restoration of the high living surname, carbon!"

Eyebrows raised slightly, Chen Xu determined the idea in his heart, and began to think about the future, if you want to smelt copper, you can't do it without carbon, if you want carbon, in addition to digging coal from the ground, you can only burn charcoal by yourself.

In this Stone Age, there were mortal dangers everywhere, their range of activities was not large, and the number of people was small, so it was undoubtedly more difficult to find an open-pit coal mine than to climb to the sky, and if you wanted to smelt copper, you could only focus on burning charcoal yourself.

"Charcoal burning? It's really a lot of work, grandma's, how do you burn it?"

After thinking about it for a long time, Chen Xu finally remembered some knowledge he saw when he was a child, and knew that the production of charcoal was caused by the incomplete burning of trees, and it seemed that with the current means, if you want to burn charcoal, you only need to set up a bonfire on the ground, and then put a few layers of wood on top of the bonfire, and then completely cover it with thick leaves, and then let the bonfire burn.

It seems that this will make some charcoal.

But after thinking about it, he still has no bottom in his heart, this method seems to be too unreliable, I'm afraid that if it is not controlled well, the entire firewood pile will burn completely.

In the end, Chen Xu thought about it for a long time, and decided to give it a try, otherwise just imagining it out of thin air here would not play a role at all, anyway, in this Stone Age, he lacked everything else, just no lack of time.

After a lot of busyness, it turned out that he was a bit wishful thinking, either the branches outside were directly burned, or the bonfire inside was directly extinguished because of the lack of air.

In the end, he realized that if he didn't add a way to leave the exhaust gas after burning inside, then under such conditions, he would never want to burn charcoal for the rest of his life.

After a few days of busyness, after dozens of failures, in the early morning of this day, Chen Xu finally burned out a few sections of black charcoal, looking at these inconspicuous pieces of wood, he couldn't help but feel some tears in his eyes.

"It's not easy, it's not easy, grandma's, it's really not a human job, but fortunately, it finally succeeded, otherwise I really wouldn't be able to hold on." ”

Wiping the dust off his face, Chen Xu couldn't help biting his lip, looking at the black charcoal below, his whole body trembled, and the excitement in his heart was self-evident.

After a few days of temptation, his original flat charcoal burning mode has also completely changed, into digging holes to burn charcoal, in the case he does not understand, step by step towards a simple cave type charcoal burning method, perhaps, this is the best proof of practice to know the truth.

The early risers around them, watching the black-faced leader behave like this to a few pieces of black charcoal, all looked strange, but in the past few days, they were also used to this kind of thing, so after a little surprise, they went their separate ways to prepare for their daily work.

Charcoal successfully appeared, after a few days of common labor, and after facing many dangers in the Stone Age together, more than 400 apes of the Vulcan tribe also truly merged together to form a big family, and there was no longer any difference between Vulcan and Black Rock, and these captives were completely heartfelt.

Realizing this, Chen Xu couldn't help but look up at the clear sky, and let out a sigh of relief, thinking, "The charcoal has appeared, and the ape-man has also fused, it seems that it is time to go to the Black Rock Tribe again, this time, not only to annex the remaining Black Rock Tribe, but also to find the copper mine there!"

"Perhaps, it's too early to mine the copper mine, but the location of the copper mine must be determined as soon as possible, as long as I annex two or three more tribes the size of the Black Rock Tribe, I will have the strength to smelt copper. ”

With his eyes narrowed slightly, Chen Xu withdrew his gaze from the distant sky, and with a shout, he gathered all the ape-men together and announced his decision to go to the Black Rock Tribe.

Hearing this news, the Black Rock Ape People did not react excessively except for their slightly dim expressions, which made Chen Xu, who had been secretly observing, nod secretly, and finally determined the effect of tribal integration in his heart.

One hundred warriors of the Vulcan Tribe hunting team, plus one hundred elites of the Black Rock Ape Man warriors, under the leadership of Chen Xu, were fully armed and formed this second hunting team.

As for the other apes, they were left by Chen Xu to watch over the house, and during his absence, under the command of the old ape-man, they continued to carry out all kinds of labor, and most importantly, continued to burn pottery and charcoal.

These two things are more and more in this Stone Age, they are the most fundamental things, and they are the cornerstone of the rise of the entire Vulcan tribe, and there can be no sloppiness.

Everything was ready, Chen Xu led more than 200 elite ape warriors, armed with bamboo spears and longbows, like warriors going to the frontier, quickly rushed into the jungle and disappeared into the territory of the Vulcan tribe.

With the experience of the previous time, coupled with the guidance of the deerskin map in Chen Xu's hand, this time the speed of everyone was much faster than the last time, and by the time everyone arrived near the pit under the big tree, the sun had not yet risen to the proper top.

When the cool forest wind blew, the road that existed as a trap appeared in front of everyone, and after so many days, the ashes burned on the road were still accumulating, and when the breeze blew, it raised a piece, like a long black snake lying in the jungle, constantly trembling lightly.

If you look closely, you will find that there are many huge footprints on the road, all of them are domineering, and in a trance, it seems that they can imagine their powerful body through the footprints.

"Let's go!"

With a low snort, Chen Xu waved his hand at the warriors behind him, and was the first to bend down and step on this path full of ashes, which was the nightmare of the Black Rock Ape Man, but it was the ladder for him to start.

It was believed that along this road with obvious traces, their speed would be one level faster, and through this dark path, Chen Xu seemed to faintly see the black rock that appeared like it, and saw the lovely apes around the black rock.

Two days later, a black shadow flashed in the jungle of the Black Rock Tribe, and it peered at the mountain rock in front of it through the hazy starlight.

This person was naturally Chen Xu from afar, but his trip was not as smooth as he imagined, and when he led the soldiers to the vicinity, he found another sign of ape-man activity.

In order to prevent accidents, Chen Xu ordered other soldiers to lurk in the jungle, and he himself performed light skills and rushed out of the jungle to investigate the situation.

As a result, the scene in front of him made his heart jump violently, and his ominous premonition was completely confirmed.

The Black Rock Tribe, which should have been emptied, was surrounded by elite warriors at this time, and these people were definitely not the people left behind in the Black Rock Tribe, because they all had elite stone tools in their hands, and they were full of violent aura, and in terms of aura, they were even stronger than the Black Rock warriors who went to the Vulcan Tribe.

And at the edge of the rock, Chen Xu noticed that some ape-man corpses were thrown directly there, and there seemed to be a faint stench coming from the night breeze.

(Write the opening report, it's almost handed in, and the other one may be late, tears run!)
