This cave was chosen and discussed after the relocation of Yanjiao, and the most suitable place to place the nucleus was decided.

The distance from the place of residence, not far and not close, does not affect the life of the tribesmen, nor is it too far to affect transportation and guarding.

Nuclei can have an impact on both living and non-living substances, especially those who are weak and have poor resistance, such as those who have not awakened the power of the totem, they can't get too close, even if they are powerful totem warriors, they need to be a certain distance away from the place where they are placed, even if they use some herbs that can enhance their resistance every day, they can't withstand the effects of nuclei at close range.

Therefore, here, the guards are still some distance from the cave, and in the middle of this place, there are dense traps, and only those who are familiar with the layout of this place can pass safely.

After Shao Xuan arrived at the entrance of the cave, he did not let the guards follow in, generally if it is not necessary, the guards do not want to enter the cave often, every time they stand at the entrance of the cave, there will always be a terrifying feeling that the alarm of the whole body is sounded, for the Yanjiao people who often hunt and have a keen perception, that feeling is quite bad, if they don't know that what is placed inside is a nuclear seed, which is an important source for making weapons, if they encounter this situation in other places, they will only choose to stay away.

The person who guarded the insect skin had already given it to Shao Xuan. After the entrance of the cave was replaced, Shao Xuan moved the big stone at the entrance of the cave, walked into the hole, and moved the stone back to block it, and the light outside was suddenly cut off, only the wind blown in by some hidden vents drove the air flow inside.

The water moon stone that was taken out was much brighter than usual in this cave, which Shao Xuan knew when he was in the desert before, and this was also the impact of the nuclear species on the water moon stone.

There was an aura of death in the cavern, which seemed to warn all living beings to retreat. That's why many beasts stay away from here.

It took a lot of effort to dig this hole in Yanjiao, and the passage in the cave was wide enough and high enough. This makes it easier for them to transport the stones. For other tribesmen, they need to rely on auxiliary means of transportation, or at the same time need a lot of manpower to carry it, but for the Yanjiao people, sometimes if the stone is not particularly large, they can carry a piece alone.

A passage leads directly to the place where the stone was placed, which was carved into a wide circular field like a square. For the sake of the nucleus, the people of Flamehorn almost hollowed out this place.

Pieces of carefully selected stone are placed there, circle by ring, ring by ring, around the core of the very center.

The better the stone, the shorter the cycle of change, and the better the smelted material. If there were no nuclear seeds, no gold tools, they would still select stone and polish it into stone tools. Nowadays it is different from the past, now everyone chooses stone to send it here, so that they can get better weapons, and people always like to change in a better direction. It's a need to survive.

Among the stones stacked around the center, there are walkways. It's convenient for people to go over and see. Every once in a while, someone would come over to see what stone had been moved to the foundry.

In Shao Xuan's special vision, he didn't need to rely on the bright light of the water moon stone, he could see the changes in those stones.

In the past, the quality of the stone would be directly distinguished by light and dark in the special field of vision. But here, the stones that have been left for a long time have begun to change, and the images presented are no longer uniform, but seem to be divided into segments. The color shades are different, and what is needed for casting is only one of the special sections, which is the metal ore needed to forge new bronze, and the metal ore in the other stone sections may be precious, but at least for now, the Yanjiao people don't need it. When the forging technique reaches a higher level one day in the future, perhaps the target will be shifted to those stone sections.

Shao Xuan didn't look at other stones, but went directly to the place where the crystals were placed, and there was a special area to place the large crystals traded from the Qi tribe, and at a glance, only it was obviously different from other stones.

At that time, Shao Xuan was just a whim, originally Zhengluo they wanted to put up those crystals, and then go to the sea to trade with the slave owners in the future, after all, the people over there prefer crystalline, beautiful and rare stones, it was Shao Xuan who asked people to send some of the large crystals here, and the rest of the smaller ones, some of them were tuned, as Zhengluo and Duokang thought they were, and they might be used for trading in the future, and the other part was taken by Shao Xuan to polish the lenses. The magnifying glass I made was used by Gui Ze to study medicinal herbs, and I also made a few telescopes for everyone to use for sentry and travel.

When I came to the place where the crystal was placed, in the special vision, most of the original light of the crystal had changed, only the surface layer had not changed much, but the inside was completely different.

Especially in the middle of the place, in Shao Xuan's special field of vision, like the bright moon, the light emitted by other stones is as dim as a star. This is also the reason why he later asked people to trade a lot of crystals with the Qi tribe and put them here, but no one objected.

These crystals, under the influence of the nucleus, have undergone very peculiar changes.

Not every stone is suitable for being placed in the area of influence of the nuclear species, some stones, such as jade, etc., are not suitable, their changes are too slow, a jade is placed here, and after a few years to take it out, the changes may not be obvious, and the better the jade, the slower the change, so that no one can have that time to wait.

What's even more peculiar is that Shao Xuan also selected some crystals from other places at that time, among which there were many stones similar to the crystals taken out by the Qi tribe, but after a while, they found that only those crystals of the Qi tribe had the most peculiar and fastest changes.

Perhaps, the crystals of the Kai tribe are not the ordinary crystals that Shao Xuan thought, and they can be treated special by the people of the Kai tribe, and it seems that they still have their own characteristics.

There are too many stones that look the same, but the essence is different, and it is not so easy to distinguish them, even Shao Xuan can't tell them with a special vision. And now, he has discovered this method of distinguishing by nuclear species, but this method takes a long time and cannot be decided in a while.

It was rare to see a stone suitable for placing in the nuclear cave, and the tribesmen would certainly not object to Shao Xuan's decision, they were more willing to create something more valuable for themselves than the benefits obtained from trading with the slave owner with crystal.

Up to now, Yanjiao has exchanged more and bigger crystals from the Yan tribe, but, because there is no way to know whether the things in the crystal are needed by Yanjiao, they have not all dragged them in, after all, if the things obtained Yanjiao cannot be used for the time being, it is better to rely directly on other stones, saving time to occupy the place, but what is obtained is a chicken rib result.

But if it turns out that the contents of the crystal are needed by everyone, and are more precious than the materials obtained from other stones, and can bring more benefits to Yanjiao, then Yanjiao will transport all the crystals he has hoarded here.

Removing the special vision, Shao Xuan looked at these crystals with the light of the Water Moon Stone.

Most of the people of the Qi tribe took out colorless crystals, and now, the original colorless and transparent crystals have become unrecognizable. The most conspicuous is, of course, Andes.

Inside the transparent crystal, the central part is covered with various colors, such as dyeing the original colorless crystal into a colorful look, and some yellow, red, gray, brown and other colors are distributed irregularly around, covering the things inside, making it impossible to see what it looks like inside.

The crystal heart was very small at the beginning, but as time passed, it slowly grew up, and Shao Xuan also felt that the crystal heart should "grow" almost, so he came here, what he needed was the most central things, not the colorful stones surrounding the crystal center, and the crystal heart was the brightest thing Shao Xuan saw in his special vision.

In the special vision, the brighter the thing, the more precious it is, this is the experience summed up by Shao Xuan's things that he has been encountering.

Because he didn't know what the crystal core was, Shao Xuan just picked the smallest crystal block inside.

After starting, Shao Xuan's hand holding the crystal block sank down, which made Shao Xuan couldn't help but be surprised.

Sink!

The crystals have become much heavier!

This is not a little bit of change, such a change is too obvious, it is directly several times the difference, and it is difficult to ignore it.

Without Shao Xuan's consent, the other people who came in to carry the stone, even if they were curious about the changes in the crystal, did not dare to move at will, they just looked at it from the side, and then informed Shao Xuan of the changes they saw after going out. So until now, no one knew that these crystals with a change in the center could be so heavy!

This also made Shao Xuan more curious about what was in the crystal heart. Put the crystal heart in the animal skin bag that had been prepared a long time ago, leave the cave, take off the white insect skin coat to the guards, and Shao Xuan took the crystal to the tribe's foundry room.

The people in the foundry room have been busy casting weapons, they hope that each warrior of the Flame Horn can have their own new bronze, but the green-faced fangs are limited, and the blood that can be taken at a time is limited, and they also have to ensure the health of those blue-faced fangs, after all, they don't know if there is an eighth green-faced fangs in this world, the original fierce beast mountain forest was so badly destroyed, how many fierce beasts survived they can't know, and whether there are green-faced fangs in the mountain forest here, no one can be sure.

Everyone still knows about sustainable development, and this kind of thing cannot be rushed.

Therefore, the people in the casting room will also have some free time, in these free time, everyone will get together to discuss the recent foundry and experience, Yanjiao is already lagging behind others in this regard, communication can promote the progress of skills, they are good at this, if they do not make any progress at all, they do not have the face to meet the people of the tribe, and they may also be replaced by others.

"Hey, Great Elder, why are you here?" The person who was chatting saw Shao Xuan coming over, and quickly got up to greet him.

"Brought something for you. As he spoke, Shao Xuan took out the crystals contained in the animal skin bag. (To be continued.) )
