"It needs some special refining methods, and the golden sword also told me, and when the time comes, I will tell you, I don't know if there is any gold sand left, and it is also very good to use it to transform other battle armors, this thing also has the effect of improving the ability of the battle armor, but the effect is a little smaller." Li Zhan said lightly.

"Hehe, this time we took almost all of the sand out there, there should be a lot of it! Take it out and take a look!" Yu Tianxiang said with a smile, turning the sand out of his pocket and pouring it on the table, and after removing the sand in it, only the sand in it remained. And everyone else did the same, and when they were all cleaned up, they were piled up together, and they looked a bit like small mountains, but in fact there were not many of them, and if they were put in a bowl, they would probably be such a big bowl.

Looking at the Tianjing Sand that was only a little bit, several people were stunned, all frowning, as if they were thinking that this bowl of Tianjing Sand could be used by several battle armors. But at this time, it was Li Zhan who said with a smile, "Oh, it seems to be really good! There can be so many, if this is put in a bowl, how can it be a big bowl!"

"Eh, that's it, more, how many armors can be used?" Xiao Yun said with a pout. "Heh, you think the celestial crystal sand is an ordinary thing! This thing is very precious, at this time, the outer heaven spar splits into sand, it is very lucky to have so much, it is estimated that there are not too many of these things on the earth. Li Zhan said with a smile.

Yu Tianxiang and the others looked at these heavenly crystal sands, and their eyes were a little green. "Hurry up, method, let's go and renovate it again. Yu Tianxiang suddenly said with a smile. After a few discussions, they began to work again.

If the heavenly crystal sand wants to have the effect of gathering spirits, it is necessary to form these heavenly crystal sands into a group, and they must be set of rings, so that the speed will be accelerated a lot, the only drawback is that it is very troublesome when combining, once the combination is wrong, it needs to be restarted, which makes Yu Tianxiang and others study for a long time to sort out the wonders of this small spirit gathering array, even if this is the case, there are a lot of mistakes in the combination, this is also due to the chain effect is too serious, one ring after another, if it is an ordinary person, even if it is an ordinary person, it will be dazzling, a dizziness stopped, I believe that few people can persist in studying for so long。 Yu Tianxiang and others were divided into five groups, Yu Tianxiang and Liu Mingkong were each in one group, Li Zhan and Xu Haoming were in one group, Xiao Yun and Fengxing were in one group, and He Jun and Liang Zhiqiang and Yang Long were in one group.

But now Yu Tianxiang and the others have been studying there for more than ten hours, and they are still continuing to study, combining them on their own battle armor, just such a small celestial crystal sand, with special techniques, but also to integrate into it, it seems very complicated, Li Zhan and the others will stop and rest for a while when they look dizzy, and then continue. But Yu Tianxiang and Liu Mingkong are constantly trying to do it, fortunately, the current technology is advanced, for the smelting of the crystal sand, there is a special flame, and they don't need to know what smelting flame they know, as long as they use science and technology, they can melt the crystal sand slightly, and then inlay it on the battle armor, so that they continue to smelt and inlay on the battle armor, without a break, just where they have been focusing on smelting. Li Zhan and the others were all inspired by the seriousness of the two, but there was still no way to be like Yu Tianxiang and the others, maybe there were some special reasons, in their opinion, maybe it was because Yu Tianxiang and Liu Mingkong had some strange abilities! This is not difficult to see from Xu Haoming's state, Xu Haoming obviously lasted longer than Li Zhan and others, but their experience was insufficient, and they only had a vague concept of this battle armor, which also caused his speed to be very slow.

For more than a day, Yu Tianxiang and others were locked in the laboratory by themselves, and they didn't go out for a day and a night, they turned off their smart instruments, even Zhang Xuerui and others couldn't contact them, and they were directly blocked. This made Zhang Xuerui and the others anxious for a while, and they didn't know what these people were doing when they were trapped in the laboratory.

"Haha! That's it. Suddenly, Yu Tianxiang burst into laughter, Yu Tianxiang got up, looked at the new battle armor in front of him, and for a while there was a trace of brilliance flashing on the battle armor, which was released by those heavenly crystal sand embedded in it, maybe these heavenly crystal sand were absorbing energy! Yu Tianxiang sensed the energy in the battle armor again, and the expression on his face suddenly changed to shock.

"Brother Xiang, what's wrong?, what's the phenomenon of your battle armor now?" At this time, everyone else curiously approached Yu Tianxiang's side and asked. "Hehe, I promise you won't think about it, now the energy in the crystal bead is continuing to rise, it seems that we have lost a lot of energy in these days! But now it seems to be recovering, and the speed is so fast, even if I use my own powerful moves now, I can recover quickly, oops, this day crystal sand is really a baby!" Yu Tianxiang said happily.

Yu Tianxiang put the battle armor on his body, but the battle armor at this time was light and fluttering, without a trace of weight, and Yu Tianxiang obviously felt that this battle armor seemed to have become much thinner, but the strength had increased a lot, and he might be able to barely have the combat power of Wu Zong. But at this time, there were some other changes, at this time the armor was much thinner, much lighter, but it became a lot tighter, much stronger, and the original gun holes and other things that were left behind, actually disappeared at this moment, it seems that at this moment this armor has become a battle armor that specializes in improving the strength of the human body, and it is not the kind of armor that can be attached to machinery or the like, this one, maybe the armor has reached perfection, and all other foreign objects are excluded. The only thing that remained was the energy shock in the palm of the hand, but the eyes on the helmet were two sunglasses-like blindfolds that became even brighter, as if it was likely to shoot a ray of light from it.

Looking at the battle armor that Yu Tianxiang was wearing, for a while, Li Zhan and the others felt different, but they hadn't experienced it personally, so they didn't know what it was. At this time, Yu Tianxiang held his hands together, his eyes flashed, and suddenly the black eyes left by the blindfold actually shot out a beam of light in an instant, and inadvertently rushed towards Liu Mingkong, and for a while, Liu Mingkong was startled.
