"What is this crystal?"

Know also can't ask the result, simply Li Xian then take the black crystal stone in the hand to say.

"The spirit crystal that the dead gathered the spiritual power of heaven and earth is called the dark crystal. It has certain special power and belongs to the variety of Spirit Crystal."

I don't know whether it's because of weakness or other reasons. Jiutian Xuannv answered directly, and didn't beat around the bush.

"Ming Jing, and this kind of thing, should be very valuable."

Li Xian said to himself, "he knows what is crystal spirit. It simply explains that the essence of automatic speaking is the essence of cohesion. Generally speaking, it is the thing used by the practitioners. It is very precious. This crystal should be considered a variant.

"Hum, I haven't seen the world before. This inferior crystal is useless. It's good that dozens of pieces can produce a little weak power. The Lingjing you are in contact with now is useless in other places."

Nine days Xuan female light hum a say.

"Yes, you are right."

Li Xian doesn't care. He's already used to the way Jiutian Xuannv looks.

Along the way, Li Xian quietly solved the zombies, but the harvest is very general, only some simple crystal, and in the conversation with Jiutian Xuannv, Li Xian has a better understanding of crystal.

According to the size and quality, the value of crystal stone is different. Similarly, according to the properties, the function of crystal stone is different, and the function of crystal stone is also different. The simplest thing is to attach it to weapons and armor to produce different effects.

For example, the dark crystal in front of us is a kind of crystal stone attached with the power of death. If it is attached to the armor of weapons, the user will enter a state of violent walking, similar to these corpses, fearless.

If it's a spar of fire attribute, it can enhance the spirit power of fire attribute, as well as other attributes.

The star sky pyroxene is also a kind of crystal stone. It has no other function. Its biggest feature is that it concentrates the spiritual power in a high concentration. According to the nine heaven Xuannv, a crystal stone the size of a palm is about equal to the spiritual power of a yuan infant realm practitioner.

This undoubtedly makes Li Xian a little strange.

"It's almost the limit."

After a long journey, Li Xian said breathlessly.

In the face of being in power, the practitioner can't absorb the spiritual power around him. In other words, he can only rely on his own spiritual power to fight. Li Xian has encountered hundreds of zombies, and the spiritual power in his body consumes a lot.

And, as we move forward, the number of zombies per time is even greater.

"This should be a low-level alien world. How could it be so huge?"

Nine days Xuan female also some don't understand to the present situation.

"I said, or today, let's go out and find a way."

Li Xian frowned and said that he was not afraid of danger, but he would not be so bored that he could not live with himself. Now, if he was besieged by hundreds of zombies, it would be a luxury to leave.

"There's no good way. You can either use human life to fill the hole, or you can take crystal stones as supplies. Damn it, if only you could get a large spirit weapon now."

Nine days Xuan girl's mood is obviously very bad.

"There's always a way."

Li Xian comforted and said that now he could see that Jiutian Xuannv was very nervous about it.

"Wait, what's that?"

Suddenly, nine days Xuan female point to the distance to say, in the voice unexpectedly slightly some excitement.

"Well, isn't it the XingKong pyroxene vein?"

Looking for sound, Li Xian saw countless faint lights twinkling in the distance, like stars in the sky.

"Probably?"

Don't know why, nine days Xuan female's voice some hesitation.

"Just look at it."

Li Xian didn't care about this. With a shake of his wrist, a huge and bright light came out of Xuanyuan sword.

With the sword light spreading forward.

Li Xian clearly saw that countless zombies were as dense as tides, and in the middle of them, the little starlight was like a giant dragon crawling on the ground, with no end in sight.

For a moment, Li Xian couldn't believe his eyes.

It's not that he hasn't seen the vein before. Generally, the veins of Lingjing are from east to west. It takes a lot of effort to mine. It should be more rare than the precious XingKong pyroxene veins of ordinary Lingjing.

However, this bare on the ground, nearly a kilometer long vein is several meanings.

After quietly calculating the time, Li Xian pulled out his teeth and rushed towards the vein of the star sky pyroxene.

This passage can only last for about an hour. There should be no doubt that there is nothing left at this moment. According to Jiutian Xuannv, if you want to open this passage next time, you need to wait for the crystal power of the array outside to recover slowly. Maybe it will take long.

Li Xian doesn't want to miss this opportunity.

At present, Li Xian engraved a leaving teleportation array in the same place according to the method taught by Jiutian Xuannv. Then Xuanyuan sword sped away, carrying countless zombies to the front of the mine.With a loud bang, Li Xian's sword fell down, the ground suddenly broke open, and the pyroxene vein in the starry sky was also blasted open.

Without looking at it, Li Xian grabbed it with his backhand and threw it into the storage space. Then he ran all the way to the transmission array that had just been portrayed, and he didn't hesitate to start it.

With a white light surging, Li Xian returned to the real world, sitting on the ground sweating.

The launch of the teleportation array requires huge spiritual power. There is no spiritual power flowing in the alien space, so it is all the spiritual power consumed in Li Xian's body. At the moment, he is almost exhausted.

Looking back at the array on the dead wood, it turned dark as the nine day Xuan girl said.

"After building the tomb, don't forget our agreement."

Almost has become a transparent nine days Xuannv, dropped a word disappeared.

Li Xian shook his head and set his eyes on the big piece of star pyroxene he desperately took out.

"That should be enough."

The following time, the Ministry of work can finally start to deal with the affairs of the God tomb, and Li Xian almost lives in the netherworld forest to study the world behind the passage.

According to the observation, it takes about two months for the channel to recover after one use.

After that, Li Xian went in alone, and then led more than ten elite experts of the Tang Dynasty to go in once, and then gave up the idea of exploring this alien world at this stage.

The more people go in, the more spiritual power will be consumed when they leave the meeting. Although there are many spiritual stones in the dark realm, in the words of the nine day Xuannu, they are rubbish, and the spiritual power is not enough.

So, Li Xian put the research center on the star pyroxene and the large spirit instrument mentioned by Jiutian Xuannu. ..
