This precipitous decline is not only reflected in the number of veins, but also in the quality of the veins.

The first-grade dark crystal veins are not only common, but also the reserve level of tens of millions is not uncommon, the second-level dark crystal veins have many million reserve levels, and the third-level dark crystal veins, not to mention the million reserve level, even the 100,000 reserve level are very rare in the Canghai Empire.

As for the fourth-level dark crystal veins, only a very small number of forces can safely possess them, and most of them only have reserves of less than 10,000 pieces.

And this pure fourth-level dark crystal vein in front of him, which was randomly placed on the ground, Lei Yuan only made a rough estimate, and found that its total amount would not be less than 100,000 pieces!

Lei Yuan's heartbeat accelerated to an unprecedented level, if this news spreads, I am afraid it will lead to a fierce competition between the four major sects and the royal family!

Could it be that the fluctuations of the Phantom Cracking Purple Polar Array are because of them?

When Lei Yuan confirmed that this was a fourth-level dark crystal vein, he could not suppress a crazy idea in his heart, and it was also because of this crazy idea that Lei Yuan would let Xiaoyu disguise his momentum.

At the edge of this strange space, there was a strange sound in the thick white fog again, and a thick murderous intent appeared in the beautiful eyes of the woman in the black dress floating in mid-air.

After all, the woman in yellow is a half-step king-level powerhouse, although she didn't expect that there would be a low cliff behind the passage, but she didn't step into the air in embarrassment, the long sword in her hand drew a few sharp scratches on the mountain wall, and the woman in yellow landed safely with Xia Lingsheng in her arms.

As soon as she landed, the woman in yellow felt an incomparably suppressed killing force enveloping her, and when she looked up, her face changed greatly.

"A king-level early powerhouse?" The woman in yellow immediately recognized the strength of the woman in black floating in mid-air, and after a thick surprise, she didn't show much fear, but a different kind of jealousy flashed on her face.

Just because, the beauty of the woman in this black dress is too unearthly, the graceful figure is like a perfect orchid blooming quietly, and the slightly tight black dress outlines the perfect curve of the woman's slender and round long legs and the slender waist of Yingying, and the woman's breasts that almost want to break the placket are even more proud.

The woman in the black dress was just floating in the air, without any movement, but she exuded a different kind of charming temptation.

This woman, just her bewitching posture is far better than the woman in yellow, although her face is covered by black ice silk, but her earthly temperament makes no one doubt the peerless face under the ice silk.

Whether it is posture or appearance, or temperament and strength, the woman in yellow was perfectly crushed by the woman in the black dress in front of her, who didn't say a word.

Women are jealous, this sentence may not be right, but it is not wrong at all when it is applied to the woman in yellow, not to mention, she is the eldest princess of the Canghai royal family, the sister of the current emperor, how can she tolerate such a perfect woman appearing in front of her safely!

"If you dare to look at it again, I'll gouge out your eyes immediately. ”

The cold and piercing words of the woman in yellow suddenly woke up Xia Lingsheng, who was completely distracted by the beauty of the woman in the black dress.

Immediately, Xia Lingsheng was mercilessly slammed to the ground by the woman in yellow, and Xia Lingsheng, who had no cultivation, almost fainted in pain.

"I am Wan Zhenfeng, the eldest princess of the Canghai royal family, who are you? At such a young age, you have the strength of the early stage of the royal level, and you must be at least from a first-class force, why hide your head and cover your face like this, are you already ugly and can't see people?" Wan Zhenfeng's last sentence didn't even believe herself, but deep in her heart, she instinctively expected and thought that this woman in a black dress who hid her head and covered her face was just an extremely terrifying ugly monster!

Although she was powerful in the early stage of the royal level, Wan Zhenfeng did not have much fear, because she was confident that with the hole cards she had accumulated in the Canghai royal family for so many years, it was impossible for the woman in the black dress to kill her. What's more, in this Canghai Empire, who would dare to kill her, the eldest princess of the royal family.

The woman in the black dress floated quietly in the air, without saying a word, even Wan Zhenfeng's moist gaze when he mentioned the Canghai royal family did not fluctuate in the slightest.

"Pretending to be a ghost!" Wan Zhenfeng's heart was furious, and her eyes suddenly noticed the thunder source on the right side of the lake, the dying thunder source did not attract much attention to her, but the fourth-level dark crystal vein beside Lei Yuan, which was directly exposed to the ground, made her pupils shrink suddenly.

"At least 100,000 pieces of fourth-level dark crystal veins!" Wan Zhenfeng's blurted out voice was almost deformed in surprise, and a thick greedy color suddenly flashed in his eyes.

One hundred thousand fourth-level dark crystal veins, even if the Canghai royal family searched all over the Canghai Empire and did not obtain one, but one suddenly appeared in front of him, and the shock in Wan Zhenfeng's heart was simply indescribable.

If a general-level consummation source wants to break through to the king-level realm, he must absorb enough fourth-level crystals, because only fourth-level crystals can provide enough pure heaven and earth source qi!

Wan Zhenfeng was stuck in the general-level consummation realm for nearly ten years, although there was a reason for her lack of talent, the lack of enough fourth-level crystals was also one of the important reasons, and it was impossible for the Rao is Canghai royal family to provide too many fourth-level crystals for her to cultivate.

But if he got this fourth-level dark crystal vein, Wan Zhenfeng had absolute confidence that he would be able to break through to the king-level realm!

This fourth-level vein must be hers!

"No wonder there will be a king-level powerhouse here, it turns out that there is a fourth-level dark crystal vein, if you want to successfully mine the fourth-level dark crystal vein, you must have a fourth-level crystal array master, and the Canghai Empire has only my royal family and the four major sects with a fourth-level crystal array master. ”

Wan Zhenfeng looked at the woman in the black dress with burning eyes, and a threatening meaning flashed in his eyes: "Your aura should not belong to the four major sects, so this fourth-level dark crystal vein has nothing to do with you, if you don't want to offend the Canghai royal family, just leave here obediently and don't reveal any rumors to the outside world." ”

The mining of the first and second level of dark crystal veins is not very difficult, only some auxiliary tools such as the excavation jade hoe used by Lei Yuan before can be used, but the mining of the third level of dark crystal veins needs to be protected by a third-grade crystal protection array, otherwise it is very easy to damage the dark crystal during the mining process.

And the mining of the fourth-grade dark crystal ore requires a fourth-grade crystal protection array, and it requires the fourth-grade crystal array master to be in charge personally, and all the miners must be crystal array masters to be able to mine, which is also the reason why Wan Zhenfeng said such domineering words.

Seeing that the woman in the black dress still didn't react, Wan Zhenfeng was furious: "Are you dumb? Don't think that I will be afraid of you in the early stage of the king level!"

"Get out of here...... Or...... Die. ”

Lei Yuan, who was about to make a move, suddenly took a break all over his body, and the qi and blood in his body accelerated by several points.

Not because of how much coercion and persecution they have suffered, but only because of ...... The voice of the woman in the black dress exiting.

The voice of the woman in the black dress is very good, the timbre is as graceful and clear as the yellow warbler in the early morning of dawn, and the sound quality is as quiet and elegant as the spring water slowly emerging from the deep mountains and valleys.

But this is not the key, the key is that the voice of the woman in the black dress is too soft and charming, and the flattering sound that hits the soul seems to be able to truly seduce the soul, even regardless of gender! Not only Lei Yuan, but even Wan Zhenfeng was momentarily stunned for a moment.

The woman in the black dress had a naturally soft voice with a hint of coquettishness, but it didn't make people feel the pretentious posture of other women at all, as if she was born to be like this.

No wonder she hasn't spoken, it's just that her voice is too ruinous to the atmosphere!

Lei Yuan's face was strange, recalling the extremely charming face of the woman in the black dress before, Lei Yuan's heart became restless for no reason, and it took a lot of concentration to restore calm.

After a short period of stunned, a thick jealousy flashed on Wan Zhenfeng's face, and he snorted coldly: "Death, it's up to you? Although you are in the early stage of the king-level, but this place has been broken into by people one after another, but you have not had any prior perception and prevention, with the perception of the king-level source, it should be easy to detect the abnormalities outside the passage." ”

"But you didn't react at all, which means that you must have suffered a lot of injuries that caused your soul perception to drop greatly, and the three of us broke in one after another, but you didn't have the slightest intention of making a move, and even that kid in the early stage of the sergeant rank was not wiped out by you, which means that your injuries are more serious than I wanted. ”

"With you like this, maybe even I can hit you hard, why do you let me die?!"

Wan Zhenfeng's successive words made Lei Yuan slightly stunned, he didn't expect this woman to have such subtle observation, in fact, this was also Lei Yuan's suspicion from beginning to end.

"Let me meet you for a while, how much strength do you have!" The long sword in Wan Zhenfeng's hand flickered, and a sword aura suddenly shot towards the woman in the black dress in mid-air.

In the face of the sudden attack of sword qi, the woman in the black dress remained motionless, her slender hand crossed a graceful curve in the air, and the pink pi lian suddenly shot out along her radiant jade hand ring, easily blocking Wan Zhenfeng's sword qi.

"Canglan Sword Technique...... Cross Sword Qi!" Wan Zhenfeng did not hesitate to use the sword technique that he had intended to kill Lei Yuan before, and the silver-gray cross sword qi erupted with a tsunami-like momentum, stirring the water on the surface of the lake into waves several meters high.

The eyes of the woman in the black dress were a little more solemn, her hands were folded, and a wonderful handprint was formed in an instant, and the pink source power flashed behind the woman in the black dress like butterfly wings, and then the butterfly wings suddenly rushed towards the cross sword qi.

The collision between the two was different from the violent explosion caused by the collision of the Desolate Dragon Seal and the Cross Sword Qi of the Thunder Source before, but this time the collision was surprisingly quiet, and did not cause any ripples of fluctuations.

I saw that the gray-white cross sword qi completely disappeared without warning, and the pink butterfly wings above stabilized after trembling violently, although the color became lighter, it still rushed towards Wan Zhenfeng at great speed.

Wan Zhenfeng dodged the butterfly wings, the pink butterfly wings blasted a huge hole in the mountain wall behind him, and the corners of Wan Zhenfeng's mouth were overflowing with blood.

In this fight, the woman in the black dress undoubtedly had the upper hand.

But suddenly, the body of the woman in the black dress in mid-air trembled slightly, and then slowly fell, floating on the surface of the lake.
