Although the scene is still a little weird, since there is no danger anymore, even if Chen Xu is still a little strange in his heart, he can't drill the horns.

After a few simple turns in this underground space, Chen Xu confirmed his understanding that there were really no creatures living in this space.

At least, in an area of several kilometers centered on the spider's nest, even the dense vegetation in the original underground space has been burned clean, revealing the dark rocks underneath.

As the saying goes, the breeze is gentle and the water is not rippling, and at this time, this area is like a quiet pond, even if the wind blows, there are no waves.

After turning around a few times and finding that there was nothing abnormal, Chen Xu returned to the copper mine area, climbed up along the hole again, and came back to the living area of the Black Rock Tribe.

After this period of construction, the apes have established several settlements on the site of the original Black Rock Tribe, relying on the original stone caves.

Piles of bonfires had also been raised, and the skinned, salted meat of the beast had been set on the grill, and the rich aroma was being licked by the tongue of fire.

Four large groups of ape-men were patrolling the surrounding jungle, occasionally driving away some terrifying beasts around them, and at the same time beginning to widen the non-trivial road to the Vulcan tribe.

Other ape-men who were not true warriors also began to get busy, and the entire barren Black Rock Territory had gradually regained some popularity after some tidying up, and had the appearance of a human settlement.

Chen Xu came out, took a breath a little, and immediately ordered someone to find the four hunting captains and began to arrange the mining of copper mines.

With the ape's current stone weapons, it is not easy to easily mine copper ore, but Chen Xu does not plan to mine it on a large scale now, he only needs to build a settlement here first, and then slowly mine copper ore to improve the weapons of the tribe.

Soon, the sky darkened, and the sun gave its last rays of light, and finally retreated into the heavy twilight, and after some intense labor of the apes, the summer night arrived belatedly.

A monstrous bonfire was lit, and the apes began to rest next to the newly built settlement.

After half a day's work, using simple baskets and ropes, the apes completely sorted out the cuprite area in the underground space and transported all the remaining good cuprite ore.

Although it was plagued by the unknown copper beast, there are still a lot of these copper mines left, just this half a day of mining and salvage, the apes have made a full dozen baskets of copper ore, in Chen Xu's opinion, these copper mines are estimated to have a thousand catties of weight.

If it is applied well, it can create at least a few hundred bronze weapons, which will bring a huge improvement to the tribe's armament.

But that's the end of the easy thing, the surface of the bare cuprite is completely mined, and the rest is a little bit of copper of different purity.

If you want to mine them from the underground space, and then refine the red copper, the difficulty is not as simple as it is now, and the difficulty of this plus one will be far greater than two.

With these red coppers, Chen Xu divided the team into two, and he led four hunting brigades of warriors to transport the red copper back to the Vulcan tribe first to build red copper weapons.

The rest of the ape-men stayed here, slowly cleaning the underground space to see if there was any remaining cuprite, and began to slowly dig into the copper ore inside.

These ape-men numbered about four or five hundred people, and they were under the unified command of the hunting captain, the Toba ape-man, and although their combat effectiveness was not as good as that of the eight regular brigades, they were not weak.

Really counted, even compared to the previous Shengfan ape warriors, it is not much better, so let them stay, Chen Xu does not have to worry at all, they are fully capable of living here.

After explaining everything, Chen Xu led the four teams of ape warriors to leave the Black Rock Tribe, and followed the road he came to the Vulcan Tribe.

It's just that this time the speed of travel is not as fast as last time, this time walking, Chen Xu directly ordered the ape-man to pay attention to opening up the road, those big trees that are more than one person thick are not easy to deal with, but the countless small trees with thick fists are much easier.

In fact, there are not many big trees on this road, many of them are thorns and small trees, as long as all these things are eradicated, if nothing else, at least this road is completely formed.

Although the apes could not understand Chen Xu's intentions, it did not prevent them from doing what they were told.

This trip lasted for three days, and all the small trees on the road that were less than the thickness of a fist were uprooted, although from the outside, you still can't see the rudiments of the path, but walking inside, you can clearly feel the existence of this road.

There were no words all the way, and after Chen Xu and the others came out of the jungle and came to the Vulcan Tribe, the other four brigades quickly set off for the Black Rock Tribe according to his orders.

This time, they had enough torches in their hands and began to use the power of the flames with the assistance of some miscellaneous apemen to completely sinter the path that was basically formed.

At the same time, more and more apes poured into this road, constantly widening this road, and according to Chen Xu's orders, they tried every means to remove the obstacles on the road.

While constantly opening up roads, he also swapped roles with the ape-men who were mining in the Black Rock Tribe, taking turns working and transporting the mined copper ore to the Vulcan Tribe.

As those copper ores were completely forged into elite bronze tools, the development of the road became smoother and smoother, and the tempering of copper ore in the Vulcan tribe also reached a new stage.

Finally, on this day, under the interaction of refined coal and copper ore, the first touch of copper water was restored in the pottery room made of clay bricks, in a mold made of some clay.

After countless continuous improvements, the structure of the kiln for copper ore refining was completely determined, and with the refining of the first copper water, the Vulcan tribe officially entered the Bronze Age.

Later, under the guidance of Chen Xu, various types of clay molds were fired, and with the gradual increase of copper mining, the tools in the tribe were gradually replaced by copper tools.

At least the weapons used by the apes now have moved out of the category of stone tools and entered the Bronze Age.

To Chen Xu's surprise, after the condensation of the refined copper water, what was obtained was not red copper, due to the simple preparation method, the purity of the refined copper was not very high, and it was doped with many other metals, such as lead and tin, resulting in the condensed copper was not completely red.

However, in this way, the hardness of these mixed coppers is much higher than that of pure red copper.

Thanks to this, Chen Xu ordered the pure copper to be returned to the furnace and mixed with other copper water, so that although the real bronze could not be obtained, the vessel could be much harder than the red bronze ware.

It's not that Chen Xu didn't have the idea of tin ore and lead ore, but he didn't even know what these two ores looked like, and he had nowhere to look for them, so he could only refine pseudo-bronzes in this way.

Despite this, the hardness of these refined pseudo-bronzes is almost half stronger than the original red bronze ware, although it cannot reach the effect of double that of the real bronze ware, but it is many times stronger than the original stone tools and so on.

With the experience of later generations, Chen Xu personally used clay to get out some simple smelting things such as giant axes and broadswords that were suitable for chopping.

It took less than a month to use these pottery as molds, and by the time late autumn approached, the weapons in the hands of the apes had changed dramatically.

With the addition of these things, the road from the Vulcan tribe to the Black Rock tribe was completely opened, towering trees were constantly cut down, piles of salt soil were sprinkled without money, wildfires were raging on both sides of the road, and teams of apes were constantly roaring.

In the end, at Chen Xu's signal, piles of river sand were carried with pockets and gently sprinkled onto the salt soil, completely covering the road surface.

When it finally took shape, a flat sand road with a width of ten meters that crossed the jungle overlord's territory appeared in the jungle, completely connecting the Vulcan tribe and the Black Rock tribe.

With the speed of the apes, if they marched with all their might, it would only take about half a day, that is, four or five hours, to reach the Black Rock tribe, which would have taken several days to reach.

With this road, the connection between the Vulcan tribe and the Black Rock tribe became closer and closer, and with this road as the center, the majesty of the Vulcan tribe gradually spread on both sides of the road.

With the continuous burning of wasteland, the opening of roads, and the encirclement and suppression of ape-man warriors equipped with pseudo-bronze tools, the surrounding jungle overlords were gradually driven out of their homes.

The first choice was to slaughter the lone liger one by one, and soon, the remaining ligon and tiger migrated far away, and as soon as the lion and tiger left, the other jungle overlords could no longer bear it, and after trying to fight back several times, but they were all beaten by the heavily armed ape warriors, they also left this place quite helplessly.

As soon as the jungle lords left, the activities of the apes became more and more rampant.

With the Vulcan tribe and the Black Rock tribe as the center, relying on the straight road connecting the two tribes, in this jungle, the scope of the Vulcan tribe has changed from a small circle around the hill to an ellipse with the hill and the black rock as the focus and the big road as the long axis.

The Vulcan tribe gradually grew, and the Black Rock tribe gradually formed a small settlement, where copper mining also entered the formalization, and with the addition of pseudo-bronzes, copper ore mining became more and more rapid.

With the steaming of the entire tribe, the late autumn season has also arrived, looking back on the development of the past few months, based on 1,800 people, Chen Xu can be said to have done a lot.

There may be some luck in it, but it is undeniable that the changes that his modern consciousness has brought to this stone tribe are huge.

It's just that although the tribe has progressed, in this world that does not belong to human beings, any development must pay a certain price, although Chen Xu has been minimizing this cost, but it still can't be avoided.

Not long ago, he conducted another survey of the population of the tribe, and found that in these months of jungle life alone, the number of ape-men who died of disease and old age exceeded four hundred.

Now, the total number of apes in the tribe is only more than 1,300, but fortunately, now that all this has stabilized, the number of casualties among the apes has gradually decreased, which has made Chen Xu's original breath of relief a little.

But even so, it made him realize the fact that the jungle is too dangerous, and it is absolutely impossible to occupy a stable position here without paying a price.

And all the time, the tribe is in constant decline, so if you want to maintain the momentum of development, then plundering the population of other tribes has become a top priority.

It seems that the time is ripe for a trip to the Infinite Land!
