The group stood in front of a large mountain range that stretched for tens of thousands of miles, and the difference between this mountain range and the side was that there was a strong miasma between the valleys. The miasma is like a white mist, with a faint purple color, which is obviously not small.

Xue Wenrui and Mu Yan saw this valley for the first time, and they couldn't help but gasp. Mu Yan couldn't help but blurt out: "This is the Dark Demon Valley! This is too big, isn't the Dark Demon Valley just a valley?"

"Hehe, I thought the same way before I came! After I came, I realized that I thought badly!" Li Feiyan said with a smile.

Xue Wenrui was also shocked in his heart, he was once again glad that he was not reckless and came alone, otherwise even if he arrived here, he would not know where to find Xuanjin Mountain.

Although there is a miasma in this mountain range, the aura is surging between many valleys, and it is obvious that there are demon beasts with advanced cultivation lurking in it. These demon beasts are highly cultivated, and they are not afraid of this miasma at all. Instead, the miasma can be used as a natural barrier here, keeping out those low-level demon beasts, demon cultivators, and outsiders.

"Didn't you say that the Dark Demon Valley was a gathering place for untransformed demon beasts?But this valley is full of miasma, how can those demon beasts survive?" Xue Wenrui couldn't help but wonder.

"The gathering place of untransformed demon beasts is only the periphery of the Dark Demon Valley, because there are few monks in the Dark Demon Valley, so the demon beasts on its periphery are gathering more and more. The demon beasts in the Dark Demon Valley are extremely rare, because they can't resist the poison of this miasma. A sixth-level Great Perfection old man explained that although he had never been here, he was aware of this misinformation.

"I see!, but Xuanjin Mountain can't be in the middle of this mountain range, right?" Xue Wenrui muttered, took out the map that the monkey ghost had prepared for him, and looked at it.

Li Feiyan glanced at the map, pointed to a gray-colored dot thousands of miles away in the middle of the Dark Demon Valley, and said, "It's that mountain peak, that dazzling black dot." This Xuanjin Mountain is famous, but the person who can go in and mine it has not yet appeared. ”

Xue Wenrui compared the location, it was really that position! It seems that this Xuanjin Mountain is among the high-level demon cultivators of the demon clan, and there are not a few people who know it. It's just that this purple-throated miasma can isolate divine thoughts, and they can only look at it from afar, and they can't see clearly at all.

"Why hasn't such a person appeared yet, is there any danger in it?" Xue Wenrui asked.

Li Feiyan explained unhurriedly: "This miasma is one of the risks, this miasma is called Purple Throat Miasma, which is extremely poisonous, and it is difficult for ordinary sixth-level demon cultivators to resist. The second is the demon beasts among them, and the demon beasts that can come here to live for a long time are all people with high intelligence, and they regard this place as their own territory, and outsiders will attack them in groups. The third is the lazuli itself, which is not only extremely heavy, but also hard and abnormal, and it is difficult to split it with a low-grade magic weapon, so it is not easy to mine it. ”

"That's a whole mountain!Is it all Xuanjin soil!" Mu Yan asked, after all, Xuanjin soil is very valuable, if the quantity is sufficient, it can be used as the main material for refining medium-grade or even high-grade magic weapons.

"It's a Xuanjin stone, not a Xuanjin earth! Or that whole mountain is a whole huge Xuanjin stone! If you can take it whole, you don't need to use magic weapons, even the best magic weapons, even weapons that surpass magic weapons can be refined. Li Feiyan replied, her tone was also full of envy.

"Xuanjin Stone!" all the monks present were shocked, even the three old men, this was the first time they had heard this allusion.

"Since it's such a heavenly treasure, why didn't the powerful cultivator take it away?" Mu Yan asked, and the rest of the people were also very curious. It's incredible that such a treasure should be left to dry here.

"Because there are high-level demon beasts that have broken through the sixth order in this Dark Demon Valley, and it is not one, maybe more than ten are possible. Li Feiyan replied with a solemn expression.

"Ten?!" several people screamed in horror.

"How many demon cultivators in the entire Demon Domain are over level six?" Mu Yan asked curiously.

"This ...... It's taboo, don't ask, even if it's an old man, don't dare to inquire about it at will!" Li Feiyan sighed and said no more.

"Senior Li, how can we get close to that Xuanjin Mountain? we can't just watch like this, right?" Xue Wenrui looked worried. If you look at it from a distance like this, it will be regarded as a condition, and he will not agree to anything.

Li Feiyan took out a jade bottle and said, "I have a few Purple Throat Pills here, which are refined with an elixir called Reverse Demon Grass. This anti-demon grass only grows in places where there is a purple throat miasma, and its medicinal properties are mutually reinforcing with the purple throat miasma, so it can refine the elixir that restrains the purple throat miasma. There are also many demon beasts below the sixth order in the Dark Demon Valley, and the reason why they can survive here is because they often swallow the Reverse Demon Grass. It's just that the old man's Purple Throat Pill is all refined with the anti-demon grass on the periphery of the Dark Demon Valley, and the medicinal properties are not high, and it is estimated that he can only enter the Dark Demon Valley for about a hundred miles. ”

He pointed to an old man and said, "Old Xiu, you and I should accompany Xue Xiaoyou in, you two are waiting here, strengthen your vigilance!" But we can only go a hundred miles, if we go further, not only will the poison of the purple-throated miasma invade the body, but we will also be found by high-level demon beasts, and we will not be able to return!"

"Thank you Senior Li!" Xue Wenrui bowed down and thanked him, this Li Feiyan didn't see any bad intentions, although his purpose was to win himself over.

"Now that Xuanjin Mountain has also seen it, why don't Xue Daoyou make an oath before going in and serve this princess for ten years!" Mu Yan asked without losing any time.

Li Feiyan listened, didn't interject, just looked at Xue Wenrui.

Xue Wenrui directly refused: "Let's wait until I come out, if this is also seen, Xue might as well not come." Of course, if Princess Mu Yan thought that she could see the Xuanjin Mountain clearly and describe the surrounding scene to Xue, Xue would admit it. ”

Mu Yan thought about it for a while, and then she didn't say much, she was worried that Xue Wenrui would not be able to see clearly after entering Baili, and she would tear up the original agreement at that time. But as soon as she thought about forcing the other party to comply, it was better to wait for him to come out before doing it.

In case the other party really has to see Xuanjin Mountain clearly, there is no need to force it. Forcing the other party to join your own clan will not do you any good.

Li Feiyan and the old cultivator, one left and one right, sandwiched Xue Wenrui in the middle, and the three of them all had a Purple Throat Pill in their mouths, and they raised their legs and walked to the middle.

Xue Wenrui guessed that because he had the Spirit Sea Tree that devoured all kinds of poisons, he shouldn't be afraid of this Purple Throat Miasma, but he didn't want to be too conspicuous, so he also swallowed the Purple Throat Pill.

The effect of the Purple Throat Pill lasted for six hours, enough for them to go back and forth. They didn't control the magic weapon and flew above the Dark Demon Valley, because Li Feiyan told them that no demon cultivator had ever been able to fly over the Dark Demon Valley alive, no matter what kind of cultivation he was.

Li Feiyan and the old cultivator are both advanced in cultivation, although they are walking among the trees in the Dark Demon Valley and still carrying Xue Wenrui, their speed is not slow at all.

Stepping into the Dark Demon Valley, Xue Wenrui found that the valley was not withered and yellow as he imagined, but lush, much greener than outside.

Xue Wenrui sensed it carefully, it should not be that these plants and trees are not afraid of the purple-throated miasma, but that the purple-throated miasma does not harm all plants and trees. "It doesn't hurt the grass and trees, but it can poison all kinds of demon beasts and monks, and the toxicity of this purple-throated miasma is really special!" Xue Wenrui said to himself in his heart.
