As soon as her words fell, suddenly from the valley, there was an extremely sharp whistling, which pierced the night sky at once, and the piercing sound seemed to pierce everyone's heart. Lan Xiang was startled, she looked up into the air, as if she sensed an extremely powerful aura slowly waking up. At this time, Gu Yan suddenly raised his face mirror and shone it towards a dark corner, "Look! ”

Lan Xiang turned her head to look over, and the vermilion mirror emitted a green glow, although it was dim, she could also illuminate it clearly, she saw it clearly, and immediately gasped, "Oh my God! ”

There is a big pit that looks incomparably wide, under the mountain wall, stretching to the endless depths, almost impossible to see at a glance, under the big pit, buried are countless white bones of the forest, skeletons of various sizes are countless, it can be seen that those skeletons are extremely powerful monsters in life.

Lan Xiang was almost speechless in surprise, she had walked in Cangwu for so many years, and she had seen a lot of strange things, but she had never seen so many demon beast skeletons gathered together, she pointed her finger in amazement and said, "Here...... At least tens of thousands, right? ”

Gu Yan was much calmer than Lan Xiang, she counted silently in her heart, and said: "This pit is at least a few miles in radius, and tens of thousands should still be estimated to be less." It seems that the missing demon beasts we talked about at the beginning were all buried in this place. ”

Lan Xiang only recovered from his surprise at this time, "Danxia Mountain is also a blessed land of immortal mountains, not the kind of poor mountains and bad waters overseas, how can there be so many demon beasts growing?" ”

Gu Yan said categorically: "These demon beasts must not have been born locally, someone brought them over from outside!" ”

Lan Xiang was surprised: "How much effort does it take to bring so many demon beasts over?" ”

Gu Yan shook his head and said, "It's not particularly troublesome, most of these demon beasts are in the third and fourth order, although they are vicious." But a Jiedan monk can easily deal with it, and the Tianji Mountain Range, which is separated from the Central Plains in the southeast, stretches for hundreds of thousands of miles. There are hundreds of millions of monsters inside, and it is not difficult to catch some from there and bring them here. It's just that Danxia Mountain is such a small place, bringing these demon beasts here. What exactly is to be done? ”

She is from a casual cultivation background, although Lan Xiang is an elder of a faction, but it is not a big faction, and she has a very clear calculation of the economic accounts, and the Yuan Dan of these demon beasts, if she takes it out and sells it, it is at least a huge amount of money. It is enough for a gate sect like Bixia Sect for a hundred and ten years, and it takes such a lot of effort and handwriting, it is definitely a great shili, and with those people of the Danyang Sect, it is absolutely impossible to do it. In Yunze Kingdom, there are such generous people, except for the royal family, there are only the Qin and Yuan families.

The two men glanced at each other, and both felt as if they were unintentional. Caught in a great secret, and they're too deep in it to get out. Gu Yan thinks about it now, back then, the Danyang faction wanted to seize the Danxia Sect. Probably wanted to seize it as a place for the array, but after Bi Zhenzhen escaped back, they didn't pursue it anymore, so as not to startle the snake, and spent a lot of effort to use the technique of making shapes according to the place to build three peaks in the distance, and at the same time left the weak sect of Danxia Sect there, probably to facilitate the blindness. Otherwise, the disappearance of a small sect for no reason will always arouse people's suspicions. Anyway, Bi Zhenzhen was also injured, and at the tasting meeting at the end of the year, the Danxia Sect would be quietly removed, and then the Danyang Sect could quietly annex the Danxia Sect and bring the entire Danxia Mountain under its rule. And the secrets in this valley will probably no longer be known to outsiders.

It's just that Gu Yan still has a question that he doesn't understand, why the Danyang faction has been so eager to do things in the past few years, and at all costs, even the danger of damaging the leylines of Danxia Mountain, they have to gather the aura here to arrange such a formation, could it be that the Danyang faction, which has been slowly plotting for hundreds of years, has suddenly become urgent only in the past few years?

With that sharp whistle, it seemed that the whole earth was trembling, and the countless trees planted around it kept shaking, and some of the bones in the pit actually flew up on their own, flying towards the sky.

Gu Yan said in a low voice: "This is the method of driving the tiger and devouring the dragon!" These people put the bones of the demon beast here, it is through the leylines of this place to nourish the corpse qi, these bones have been sealed for many months of adulthood, and they have begun to conjure up demon qi on their own, which is the most powerful food to nourish the demon beast! ”

She looked around and pointed to the nine towering trees around her, "That's the Nine Dragons Lock Bead Technique, which locks the leylines here tightly, and the aura can't leak out, and it can't be hovered here, the living water changes into stagnant water, and the aura turns into dead air, which is used to nourish tens of thousands of bones. ”

She was indeed extremely surprised in her heart, different from the demon gate methods she saw when she was in the dungeon, the formation layout here, although terrifying, was a real Taoist technique, there must be a person who knew everything about formation and alchemy, to be able to make such an arrangement. Whether it is the use of the surrounding terrain, the understanding of the spiritual veins, or the control of the way of the formation, this person's level is better than Gu Yan, Gu Yan has been in Cangwu for a long time, and it is the first time he has seen such a talent. Sure enough, as soon as he arrived in the Central Plains, he hid the dragon and crouching tiger!

Lan Xiang suddenly pulled Gu Yan with his hand and exclaimed, "Look! ”

The place where they were standing was not too far from the pit where the bones were buried, just in the middle of the nine giant trees, at this time, from the underground, I don't know when, a layer of white gas had already surged, floating from the ground, about a few inches above the ground, rolling up against the ground, and everywhere they went, all the wild grass spreading on the ground died, and suddenly turned scorched yellow. This white gas came from all sides and was close to the ground, and in a blink of an eye, the two people were surrounded in the center. At the same time, around the city, there were sharp whistling sounds, and in all parts of the river valley, there were sky-high fires, and Lan Xiang whispered: "Our whereabouts seem to have been discovered!" ”

Gu Yan was still quite calm at this time, and she said in a low voice: "Probably not!" This dead qi should be at the peak of the Taiyin every time, and the Nine Dragons lock bead should be released through a hole to vent half of the yin qi, otherwise the yin qi will be too strong. It is easy to regurgitate the spirit vein itself. But we're going to find a place to hide right away! ”

Lan Xiang didn't study the way of formation, so naturally everything was under Gu Yan's orders. Sure enough, after the firelight rose into the sky, it seemed that there was no movement around it. There were just a few pillars of fire hanging high in the air, like a signal, signaling the coming of the child time.

But that dead breath has spread rapidly to the earth. About to surround them, Gu Yan whispered, "Where we stand." Just as the center of the Nine Dragons Lock Bead, the dead qi zuihou will all gather here, and then it will be dissolved through the power of the Taiyin Yuehua, let's go first! With a wave of her hand, she raised her vermilion mirror, and the twelve beast heads roared, spewing out thick green gas. The sky around them suddenly darkened.

The brilliance on the Zhuyan mirror is constantly changing, the dark clouds and green trees in the sky, the scenes flash quickly on the mirror, the mirror is as smooth as water, Gu Yan's five fingers are like a smart butterfly, and the aura around them is constantly changing.

Cold sweat soaked slightly on Gu Yan's forehead, and he didn't have time to wipe it, Lan Xiang raised his head. I only saw the five flag gates floating in the air that had been following them, and with Gu Yan's movements, they were also constantly changing their directions. The dead aura of the outside world was also changing violently at this time, and Lan Xiang had a feeling in his heart that these two completely different breaths, like a lock that had been broken in half, were exchanging with each other, trying to find a way to fit together.

Suddenly, Gu Yan stopped his hand and let out a long breath, all the aura around him was gathered by Zhu Yanjing at the same time, and the formation of the five flag gates quickly narrowed inward, and the two of them also brushed it and disappeared from the flat ground. When he reappeared, Lan Xiang only felt that his feet had stepped on the top of a giant tree. Now they are dozens of feet above the ground, observing the situation here.

Gu Yanchang took a breath and shook off the tired look on his face, "The people who set up the formation, the technique is really bold!" Nine Dragons Lock Bead, he actually left the exit at the door of death, and the two dead gases collided, and he was not afraid that he would backfire on himself because of this! Under the attack of the two dead airs, Gu Yan used the method of dying and surviving, and finally got out of the door of death and reincarnation, but it also made her break out in a cold sweat, she has entered countless formations in her life, and the ancient formation diagram has also experienced more than once, in comparison, the technique of this array person can really be said to be one of the best.

Lan Xiang pulled her and said, "You can see it again!" She pointed to the air with her hand, Gu Yan looked up, she hadn't bothered to observe the situation above her head just now, and when she looked at it again, she couldn't help but be surprised.

The two people raised their heads and looked, at this time there was a thick layer of fog in the air, behind the fog, it seemed that there was an incomparably huge demon beast hidden, under the cover of the endless fog, only the faint figure could be seen, its body was dozens of zhang long, stretched at both ends, at a glance could not see the edge at all, on the huge and slender body, there seemed to be countless tentacles, wriggling, behind the clouds, there was a blood basin mouth open, those bones in the pit, It was sucked into the mouth by the blood basin.

Lan Xiang exclaimed and said, "These bones were originally fed to this monster!" ”

It was about half an hour before the castration of the bones flying into the air began to slowly stop, and the giant beast seemed to have eaten and drunk enough, and its body began to fall, slowly falling into the valley mouth. And looking at the big pit on the ground, it has gone to a shallow layer.

The white bones piled up in that big pit were probably only more than half of the pit, Lan Xiang said with palpitations: "No wonder this pit is not full, it seems that the upper half has been fed to the belly of that demon beast in the past few years!" ”

Gu Yan was also shocked by this great discovery, she had traveled north and south, she had experienced so many places, and she had even seen the bones of the divine dragon, but such a huge and ferocious demon beast was still unseen. She frowned and said, "These demon beasts should have all been swept from the Tianji Mountain Range to make a meal for that giant beast. When we first entered the valley, the fog poisonous insects we saw should be used to devour the corpse of the demon beast, devouring all the flesh and blood on the corpse, leaving only the bones, and the Yuan Dan contained in the body of the demon beast. But what exactly do those demon insects you saw at the beginning do? ”

As soon as they entered the valley, they saw the strange insects that covered the low bushes, which were killed at night, leaving white eggs that reborn as adults at dawn. This life is repeated over and over again every day. It must have something to do with this giant beast.

Lan Xiang's face was worried, "It doesn't matter if these are true, but again." Do we want to go on or not? What Lan Xiang raised was a very real question. Gu Yan and her are only passers-by of Danxia Mountain. It's only because he has a personal friendship with Bi Zhenzhen that he will come to help with this. Go here to find the demon insect that injured her, and see if there is a way to heal her injuries, but neither of them will have a grudge against the Danyang faction because of this. After all, the two of them are the value of the elders of the Bixia Sect, and once it is revealed, it is very likely to cause the confrontation between the two sects, which is something that they can't ignore as the elders of the Bixia Sect.

And the complexity of this river valley is far beyond their expectations. Here, they have already encountered unknown demon insects, countless fog poisonous insects, endless demon beast bones, and a huge demon beast of unknown origin, coupled with these esoteric formations, the mysterious figure behind them is really not something that can be shaken by the identity of the two of them. So Lan Xiang was a little upset. This is not because he is greedy for life and afraid of things, but because of his worries as a sect elder.

Gu Yan has always been a loner, and he takes less care of these things. Since the beginning of her cultivation, she has provoked a lot of enemies, and she has come to this point safely, in essence. Although Lan Xiang is flying on the outside, he is still a little more stable in his heart. But what Gu Yan is thinking about now is what secrets are hidden in this river valley?

Obviously, the person who set up the formation, using the method of making shapes according to the place, created the momentum of "Locking the Dragon Hidden Hill", and laid the formation of the "Nine Dragons Lock Beads" here, just to gather all the leylines and spiritual energy here, so it was mostly used to nourish this demon beast. Those unknown demon insects, although they don't know the purpose, are inseparable from this demon beast.

Seeing that Lan Xiang had already retreated, Gu Yan smiled bitterly: "If you want to get out now, I'm afraid it's too late, since this is the trend of locking the dragon hidden hill, then at the peak of the Taiyin Qi at night, we can't get out of here, otherwise the Nine Dragons Lock Bead here will firmly lock us here, and trap the two of us with the essence of Taiyin, until the turn of the second time, and then the Yin Qi will trap us, and the two dead gases will fight each other, and we will be trapped in the ground forever until we are eroded by these dead gases, until it becomes a bone. ”

Lan Xiang stuck out his tongue, "So powerful!" She heard the meaning of Gu Yan's words and said, "So, is it only at dawn that we have a way to get out of here?" ”

Gu Yan said: "Yes, at noon, when the yang energy is at its peak, I have a way to break through the yin energy here, so that the momentum of the Nine Dragons Lock Bead will fail, and then I can get out." It's just ......," a playful look appeared on her face, "Come to this river valley, do you really plan to go home empty-handed?" ”

Lan Xiang couldn't help laughing, Gu Yan's expression made her feel relatable, speaking of which, she was more lively than Gu Yan, but as an elder of a faction, she had to think more about things, but from the heart, when she was young, she was also a character who was afraid that the world would not be chaotic, and now that she knew that it would take at least six hours to get out, she no longer mentioned leaving, but consulted with Gu Yan.

Rao is temperament is flying, but she was still taken aback by Gu Yan's thoughts, according to Gu Yan's thoughts, she wanted to go to that valley to explore!

According to Bi Zhenzhen, the valley where the giant beast was hiding was the place where she had been attacked. A few years ago, there should not have been that big pit here, and there were not so many arrangements in the valley, all of which were built in just three years. Although Gu Yan had no way to immediately break through the surrounding Nine Dragon Lock Bead terrain, she was still somewhat sure of quietly going to the valley to explore without alarming those Danyang Sect disciples here.

Lan Xiang thought about it, but she couldn't help but be tempted by Gu Yan's thoughts, and she also wanted to know what kind of monster that giant beast hidden in the deep valley was. She whispered: "Taniguchi is deeply locked by clouds and mist all year round, probably not ordinary fog, are you sure?" ”

Gu Yan also replied in a low voice: "That should be the breath spit out by this demon beast, the yin qi that has accumulated for many years, with the terrain here, has evolved into dead qi, it is a natural valley mouth barrier, ordinary people can't get through, but I also have a way." She raised her head and looked at the stars in the sky, "There is still a pillar of incense left, and the Tianxuan star position will fall here, and then the yin qi will be weakened to a small extent, so we will take this opportunity to enter!" ”

The time of a pillar of incense passed in the blink of an eye, and the two of them were ready, Lan Xiang took the two talisman magic weapons in his hands, and prepared to release them when he encountered an accident for a while, Gu Yan also held Zhu Yanjing in his hand, and then both of them were on Gu Yan's Jinyun disk, she had already converged the treasure light of the Jinyun disk at this time, and looked at it from a distance, it was just a gray ball of green energy, and then quietly floated to the top of the valley mouth.

When they got to the top, they could see the terrain below more clearly, this valley was a gourd-shaped narrow land, the valley mouth was very small, but the terrain below was extremely deep, and the valley mouth was shrouded in clouds and mist all year round, so they couldn't see the situation below at all. As soon as I approached the clouds and mist at the mouth of the valley, I felt a heavy fishy smell rushing to my nose. Gu Yan patted Xiao Jiang who was standing on his shoulder, "Break it!" ”

Xiao Jiang whined twice, and without saying much, he stood on Gu Yan's shoulder, shook his head, and the purple gold electric light shot out from the two purple pupils, like the scorching sun melting snow, there was no sound, and the clouds and mist below were silently broken, Gu Yan pulled Lan Xiang's hand, and the two of them quickly sank into the clouds, and then the clouds and mist closed silently, in the eyes of outsiders, as if no one had ever entered.

The clouds are several zhang thick, but fortunately, Xiao Jiang's purple eyes are even more powerful after being promoted, and the purple light shoots forward, no matter how thick the clouds are, they pass through, and the two of them quickly passed through the clouds and saw the situation below.

On the ground, there are thick layers of fallen leaves, and under the fallen leaves, there is a fine white sand, and it is impossible to see how thick the sand layer is. Gu Yan said in a low voice: "It's the corpses of those demon insects!" ”

Lan Xiang also saw these scenes, she couldn't help frowning, these fine sand accumulations are at least a few zhang thick, those demon insects will die hundreds of millions of times a day, and the corpses are accumulated, almost as vast as a sea of smoke, just thinking of being in the same place with the corpses of countless insects, she unconsciously felt a burst of discomfort on her body.

Looking at the surrounding terrain, Lan Xiang said a little strangely: "There seems to be no other secret passage here, where did that demon beast go?" "All around are hard mountain walls, straight as knives stand on all sides, and the ground is thick with fallen leaves and insect corpses. I can't even see a cave, and naturally there won't be any secret passages.

Gu Yan and Lan Xiang had the same feeling, although she could ruthlessly kill no matter how vicious the demon beast she was facing, but it still felt a little strange to be in the same place with so many unknown demon insect corpses. She shook her head, discarding this strange feeling, and said, "The demon beast should be hidden deep in the belly of the earth, but there is no ......passage here," she said in a deep voice, "Could it be that this demon beast knows the method of five escapes?" ”

Lan Xiang was a little surprised and said, "How is it possible!" Although it is said that there is an earth spirit beast that is inherently proficient in the Five Elements Escape Method, but the size of this demon beast is so huge, how can it be so psychic? "Generally speaking, if the volume of a demon beast is larger, then the tougher it will be, but in the same way, with the strength of the beast, its intelligence will be even lower, which is also the reason why the general large monsters are hidden in the deep mountains or the bottom of the sea, and it often takes thousands of years for them to cultivate spiritual wisdom. Unlike those small beasts the size of cats and dogs, they are born psychic.

Gu Yan groaned and said: "It's not impossible, this is related to the bloodline of the spirit beast, if this spirit beast has the bloodline of the ancient spirit seed......" She said this, and suddenly hit her forehead, "I remember, what is that demon beast!" (To be continued)
