? Strange purple 'colored' crystals, diamond-shaped, exuding extremely strange energy 'waves'. This kind of energy 'wave' is different from the energy 'wave' that is common in cultivators, but it is somewhat similar to the energy 'wave' that is unique to this world.

It's not that there are no energy 'waves' in this world, it's just that there is no heaven and earth aura! There is also a large amount of energy between heaven and earth in this world, but these energies are just unable to absorb them.

There were so many of these diamond-shaped crystals on the walls of the chamber, and each one exuded a brilliant brilliance, which was too much if it was used for lighting.

Seeing these strange crystals, Chen Yuxiang instantly understood what kind of magic weapon was used by Coca in this world to refine the magic weapon!

These strange purple 'colored' crystals form a spiritual enlightenment array. Obviously, Coca used such a spirit initiation array for magic weapons to complete the enlightenment!

Retracting his gaze from the crystal without a trace, Chen Yuxiang sat down cross-legged and watched as Coca continued to refine the weapon. Wu Zixiong also sat down cross-legged, and Master Coca's face was indifferent, and all his body and mind were immersed in the '' control of the real fire, and he didn't pay attention to Chen Yuxiang and the three of them at all.

Chen Yuxiang's eyes were locked on the magic weapon in front of Master Coca, but there was a huge 'wave' in his heart. This kind of strange crystal, this is not the first time he has seen it. Now that he saw this crystal again in this world, his heart naturally couldn't calm down!

Danyang Xia Ziyan leaned on a fairy sword and pressed the Rakshasa Mage Tower alone. When Chen Yuxiang's divine sense scanned the City of Holy Light, he had also seen this 'girl'. That fairy sword made a very deep impression on Chen Yuxiang.

Xia Ziyan's fairy sword is exactly the same as the Qinggang sword, the difference is that within the seven grooves of the sword handle, the Qinggang sword is usually inlaid with the best spirit stones, and after the spirit stone is inlaid with it, the Qinggang sword will immediately absorb the energy, while the fairy sword in Xia Ziyan's hand is inlaid with seven strange purple 'color' crystals in the grooves!

The appearance of the crystals is exactly the same as the crystals above the secret room, but the volume is slightly smaller.

These two crystals are actually one of the kind. The crystal on the Xia Ziyan Flying Sword is slightly smaller, that is because the groove on the hilt of the sword is only so big, and the crystal itself will automatically become smaller during the inlay process, just like the top grade spirit stone inlaid on the hilt of the Qinggang Sword.

"Xia Ziyan's immortal sword should be something from the 'immortal realm' of the intermediate plane. These crystals inlaid on the hilt of the sword are naturally energy sources from the intermediate plane. After all, immortal weapons and magic weapons require different sources of energy, and Xia Ziyan is a human realm monk after all, so it is impossible to generate energy that can drive the immortal sword. She was able to use the Fairy Sword, apparently because of the power provided by these crystals. ”

"In this way, these crystals should be similar to my 'Wood Essence' Hua! Of course, I'm afraid that the level is still inferior to my Wood Essence Hua. The abundance of this crystal in Coca suggests that it is a common energy source in the Intermediate Plane. And my Wood Essence Hua should be a more advanced energy source, in the intermediate plane, it is estimated that it is the status of ordinary spirit stones and top-grade spirit stones!"

"What does this mean? It means that my guess should be correct, this Void Prison is really an intermediate plane! Otherwise, my natural bow should not be opened at all, this kind of crystal used on the fairy sword cannot appear in large quantities at all!"

"This kind of item, let's call it fairy crystals! There are so many fairy crystals in coca, obviously this thing is not a precious thing in this world. However, Coca obviously understands the value of these crystals, and is already using them instead of the best spirit stones to set up the spirit array!"

"No wonder Coca can mass-produce high-grade magic weapons! Using this kind of energy source from the intermediate plane instead of the best spirit stone to complete the enlightenment, the resulting instrument spirit is naturally much better! And a good machine spirit is the greatest guarantee for the grade of a magic weapon!"

After Chen Yuxiang came to this world, he knew that each of the three major forces had a refining master who could disassemble low-level magic weapons and refine high-level magic weapons. And in this world, the price of magic weapons is definitely not too expensive. For a long time, Chen Yuxiang has been 'confused' and 'confused', how did these refining masters complete the spiritual enlightenment of the magic weapon? After all, the spiritual enlightenment array of high-grade magic weapons must be completed with the spiritual enlightenment array of the best spirit stone.

Now all doubts and 'confusions' have disappeared! The appearance of this kind of "immortal crystal" has solved all of Chen Yuxiang's 'confusions' and 'confusions'. Obviously, not only coca, but also the refining masters of these forces should use this kind of immortal crystal to set up the spirit array. It was precisely because of this that they were able to use the raw materials dismantled on top of the low-grade or medium-grade magic weapons to refine high-grade magic weapons that were close to or even surpassed the Qinggang Sword!

However, their use of immortal crystals is probably limited to this! The energy in the immortal crystals is obviously impossible for cultivators in the human realm to absorb, otherwise everyone wouldn't have to be so crazy about snatching spirit stones! And Ying Qin's establishment of a blood pool to provide energy for the natural bow shows that these immortal crystals have not been embedded in his natural bow. At least, Ying Qin did not master the method of mosaic.

Seeing these crystals, Chen Yuxiang was even more convinced, the Void Hell was an intermediate plane, and it should be at least a transitional plane, otherwise it would be impossible to explain the appearance of these immortal crystals. This naturally caused him to have greater doubts and 'confusion' in his heart.

Why can a family in a lower plane control a middle plane?

Since the Xia family can control this plane, why don't they move to this world to survive? After all, they can completely get rid of the pain of life and death here, and as for the spirit stones used for cultivation, with the Xia family's status on the Kyushu Continent, it is not a problem to move dozens of spirit veins.

In front of Coca, the real fire is still rising. Chen Yuxiang looked at the coca refiner and pondered these questions at the same time.

About an hour and a half later, the true fire in Coca's hand rolled back and was withdrawn into his body, and the narrow flying sword was still floating in front of him.

Looking at the flying sword in front of him, Coca's eyes showed a solemn 'color', his eyes looked at the flying sword for a moment, and he muttered: "This is the last work of the old man! I hope that this time my luck is good enough, and I can refine a better magic weapon!"

After speaking, Coca waved his hand, and the fairy crystal on the wall shone brightly, and in the void, more purple 'colored' diamond-shaped crystals appeared. A faint coercion emerged in the chamber, as if a huge soul had been awakened.

In the face of this kind of coercion, Chen Yuxiang and Xiao 'Mao' didn't care at all, but Wu Zixiong saw sweat on his forehead, and his face became extremely pale. Sweat instantly soaked his clothes, and he was still gritting his teeth.

Coca still didn't care about the changes in the outside world, he snorted, and his hands played a few tricks like the wind, and on each piece of purple 'color' crystal, there was a thin line of purple 'color' energy that seemed to be there, which was entangled on the magic weapon, and then on the surface of the flying sword, a layer of purple 'color' appeared in the glow.

The purple 'color' brilliance seeped into the flying sword like water, and the aura of the magic weapon was also slowly changing. Chen Yuxiang watched all this for a moment, trying to remember every trick that coca played. After all, coca has more than 100,000 years of refining experience, which is extremely rare among the cultivators of the human realm. His refining technique has definitely reached the highest level of refining magic weapons. And these, after he leaves this world, can become the most important wealth of the Hehuan Sect!

The process of enlightenment lasted just half an hour. Coca had indeed completed the refining of this magic weapon in two hours. After Coca played the last trick and the purple 'colored' crystals in the room disappeared, a brand-new high-grade magic weapon was freshly baked!

Compared with the flying sword that has not completed the spiritual enlightenment, the flying sword at this time is like having its own spiritual 'nature'. Such a magic weapon, if there is no such high-level instrument spirit, is limited by the material, even with the ability of coca, it can at most surpass the lowest level of high-level magic weapons. It is precisely because of the existence of this high-level instrument spirit that the magic weapon has a level close to that of the Qinggang Sword.

However, it was clear that Coca was not satisfied with "his last work", and after a sigh, the flying sword flew automatically to the wall and hung up.

This flying sword, for Coca, is just an ordinary work, and the most anticipated top-level work, just like the Cold Crystal Sword, he himself has been able to refine one once in a while for a long time.

"Two, please do it!" Coca sat up straight, looked at Chen Yuxiang and Wu Zixiong and said calmly.

"Hehe, master, why should I kill you?" Chen Yuxiang looked at Coca and smiled.

"I'm also the one who won Qin, won't you kill me?" said Coca in surprise.

"Only coca is not evil, I have heard this sentence a long time ago! We killed Ying Qin, but it was only because this person was violent and wanton, and did many evils. I came to disturb the master today, just to discuss some refining techniques with the master. Chen Yuxiang looked at Master Coca and smiled, "In addition, the new owner of this manor is under the order! If the master does not give up, he can still refine weapons here, and I will absolutely guarantee the safety of the master!"

"As long as I can continue refining without being disturbed, it will be the same for whoever I refine. Coca looked at Chen Yuxiang and said, "But there is one thing, I don't call you master." When Win Qin was there, he also treated me as a guest. ”

"This nature, I have great respect for the master, how dare I treat the master slowly!" Chen Yuxiang smiled.

"That's good!" Coca nodded, "You said you want to discuss the technique of refining weapons with me, that is, you also know how to refine weapons?"

"I understand a little. Chen Yuxiang smiled and said, "But after coming to this world, I really haven't refined a weapon! The main reason is that there are not enough top-grade spirit stones, and I can't enlighten the magic weapon at all." When I saw the master's refining today, I felt an eye-opener. Master, what are these crystals that you use to enlighten your soul?"
