Ten days later, in the middle of the willow sea, three streamers quickly jumped into the void and walked towards the northern land of the Outer Demon Star, where the territory of the Dry Bone Ancestor was located.

According to what the Sword Demon and Bi Liu said, the Dry Bone Ancestor cultivates the "White Bone Demon Thunder", and every time it comes, he will go out to find the spirit bone to cultivate, and this time is also the most difficult time for them to ambush, if he misses this opportunity, I am afraid that he can only be found by the Dry Bone Ancestor who is promoted to the fourth order of the Immortal Thunder, and at that time, everything will be too late.

The world is vast, the land in the north of the Outer Demon Star is bitterly cold, the earth is withered, the forests are sparse, and the large wasteland is continuous, there is no end in sight, this is a dead land, it is a forbidden area of life, even the demon cultivators of the Thunder Infancy rarely come here.

However, such a place is not the slightest problem for the three ancestors of the Outer Demon Star, although this place is desolate, but it is full of infinite demonic nature, occasionally, when a breeze blows, there will be a burst of ghostly roaring sounds, as if this place has gathered all the dead lives on the Outer Demon Star here, making it a different kind of hell.

It is rumored that this place was caused by the formation arranged by the Heavenly Demon Sect, gathering thousands of yin qi to form a place of yin death. However, with the Heavenly Demon Sect giving up on the Outer Demon Star, the formation in this place is also constantly decaying, and the yin qi in this place is becoming less and less, if it is hundreds of thousands of years later, this place will definitely return to normal.

But these are a little early for the three ancestors, in such a hellish place, the three ancestors are like fish in water, absorbing the yin attribute thunder power in it, strengthening their own bodies, and finally being able to dominate one side, making the outer demon star form a three-legged situation.

Of course, the cultivation of the three ancestors is high and low, the highest of which is the dry bone ancestor, his cave is far away in the white bone cave in the north, this white bone cave is extremely north, only a few hundred miles away from the extreme north, where the yin wind roars, and there are terrifying yin spirits guarding it all year round, and it is difficult for ordinary people to enter it.

In the White Bone Cave, there are countless white bones inside, and there is no shortage of spiritual bones of some powerful cultivators and thunder beasts. And the Dry Bone Ancestor grabbed the spirituality from these dry bones, using the bone as the root, and finally achieved the prestige of the Dry Bone Ancestor.

The cultivation of Sword Demon and Biliu is slightly inferior, and their cave mansion is even farther away from the Far North, and they will not easily set foot in the Far North Land in normal times, because it is the territory of the Dry Bone Ancestor, and if they set foot in it, it may cause a big war.

Demon Cave, here is a dangerous place in the northern land of the Outer Demon Star, it is rumored that there were extremely powerful creatures buried in it, and there have been strange changes, there will be a ghost tide every ten days and half a month, and then infinite ghosts will pour out of the Demon Cave, like a tide, red and black all over the ground, especially terrifying.

In this ghost tide, there are many powerful ghost creatures, they are all some cultivators and thunder beasts who have cultivated to be strong in their lifetimes, even if they lose their spiritual wisdom and turn into ghosts after death, but their instincts are still there, coupled with the infinite yin power they possess, even the cultivators of the thunder infancy stage have the possibility of falling.

Therefore, on the Outer Demon Star, whenever the Demon Cave is talked about, every Demon Cultivator will change color, which shows that the Demon Cave is terrifying, even if it is as fierce as the Demon Cultivator, it is also extremely terrifying.

But although this demon cave is terrifying, sometimes there will be surprises, when the ghost tide occurs, the demon cave is not only releasing endless ghost things, but also may spew out some thunder soldiers, spirit bones and other things.

These are all buried in the demon cave of cultivators, thunder beasts left, after thousands of years of experience still exist, you can imagine what kind of powerful things these are, so, even though the ghost tide of the Dao is very dangerous, but every time the ghost tide breaks out, there are still many self-sustaining cultivators who rush to the demon cave, waiting for the ghost tide to arrive, hoping to get some treasures.

The Dry Bone Ancestor is even more of a frequent visitor, because the spirit bones required to cultivate the "White Bone Demon Thunder" are very large, and the cultivation to the depths is also very high. Therefore, the Dry Bone Ancestor hit the idea into the demon cave, basically every time the ghost tide broke out, there was the shadow of the Dry Bone Ancestor, and this was also the biggest basis for the Sword Demon and Bi Liu to be sure that the Dry Bone Ancestor was here.

"Brother Yu, there is the Demon Cave ahead, the environment here is treacherous, the wind is rolling, you are here for the first time, but you have to be careful. In the void, the Sword Demon cautiously reminded that dozens of miles in front of him, a cave with a radius of hundreds of zhang was presented in front of Lei Yu.

This cave is dark and gloomy, eerie and terrifying, it is not clear at all, even if the divine thoughts radiate out, they will be swallowed up, as if there is some strange existence in this cave, which can block the visit of the divine thoughts.

"Whew!" the yin wind blew, coming out of the cave, this cave was like a passage to the Nine Hells, eerie, and there were some miserable voices of ghosts screaming, floating in the sky, even in the daytime, it still felt that people's bodies trembled.

This is the Demon Cave, a place of demons, strange and unfathomable. With the Demon Cave as the center, it was pitch black within a radius of thousands of miles, as if the land had been cursed by something, and there was no other color except black.

The mountains and rivers are reckless, but they are withered, without the slightest vitality, and the demon cave seems to be absorbing the vitality within a radius of thousands of miles, making all life extinct here, becoming a barren land.

Lei Yu frowned slightly, and a sense of awe couldn't help but rise in his heart. It stands to reason that this place is a yin land, and it can be said that he is like a fish in water for him who cultivates the "Nine Shadows Yellow Spring Thunder", but now he feels that he is being targeted by a fierce beast, and his every move falls into the eyes of the other party, and maybe the next moment it will become the food in the other party's mouth.

Lei Yu didn't like this feeling, he didn't like to give the initiative to the other party, especially after he was promoted to the Immortal Thunder Period.

"Thank you Brother Shi for reminding me!" Lei Yu said, pressing the uneasiness in his heart, after ten days of getting along, he and the Sword Demon and Bi Liu are no longer strangers, and they have changed a lot in terms of title.

"Ha Luha, Brother Yu is coming to this demon cave for the first time, and he doesn't know much about everything here. In this way, you will follow Shi, and you will never be at a loss. The Sword Demon Ha Luha smiled, paused in the void, and immediately headed towards a mountain peak below.

Naturally, Lei Yu was not suspicious, and turned into a streamer of light. And the same is true of Biliu, who soon settled on the top of a mountain.

"Brother Yu, as you can see, this huge cave in front of you is a demon cave, and it is rumored that a powerful creature was once buried here, which led to such a change. At ordinary times, the demon cave is not very irritable, only when the ghost tide comes, the demon cave will really open, and when the time comes, this demon cave will be like the underworld, and endless ghosts will gush out of the demon cave. ”

"And at this time, the Dry Bone Ancestor will definitely come, we just need to wait for the rabbit, and even if we can't kill him at that time, it will be enough to severely damage him. ”

A hint of anger appeared in the Sword Demon's eyes, obviously he had already had the intention of getting rid of the Dry Bone Ancestor in his heart, and he would inquire about everything about the Dry Bone Ancestor.

"Brother Yu, this time to kill the Dry Bone Ancestor, mainly Shi Daoyou and concubines, you only need to assist us and others, and it doesn't take much risk. As early as half a year ago, the concubine body had arranged the 'Biliu Great Array' around it, although this array did not have any attack power, but the concealment aspect was extremely strong, even if the dry bone ancestor could not be found in a short time. ”

"When the time comes, you only need to hide in the 'Biliu Great Array', listen to my orders, and combine the strength of the three of us, and you will definitely be able to succeed. ”

Green Willow's beautiful face was full of smiles, but her tone was extremely cold, like a poisonous scorpion, although beautiful, but full of danger.

"Thank you, fairy!" Lei Yu said with "peace of mind", looking like he was relieved. And Lei Yu's movements fell in the eyes of Sword Demon and Bi Liu, and the two glanced at each other, and they both saw a hint of a smile in each other's eyes.

Although this "Biliu Great Array" can be hidden, it is also a trap. If the time comes, the two of them are defeated by the Dry Bone Ancestor, they can expose Lei Yu, buy time for the two to retreat, and even push everything on Lei Yu's body and make him a scapegoat.

"Hmph, if you want to plot against me, you have to see if you have that ability!" Lei Yu snorted coldly, pretending not to see the movements of the two, and entered the "Biliu Great Array" alone, he is a "killer weapon", and he will use it at the most critical time.

The land is vast and dark, and it is impossible to distinguish between day and night. A bright moon slowly rose into the sky, looming in the thick clouds, the miserable white moonlight shone down, and there was a trace of cold light on the black earth, which looked very weird.

The neighing of ghosts continued to sound, and the night here was more like a ghost domain, and the cold evening breeze blew, kicking up a cloud of black smoke and dust, and these neighing sounds were transmitted farther away, so that the territory within a radius of thousands of miles with the demon cave as the center was shrouded in a terrifying atmosphere.

The demon cave is still dark, dark and secluded, and it is not known where the road leads, as if it is really connected to the Nine Hells. Occasionally, one or two ghosts would spit out of the cave, walking on the black earth, dazed and unsane, and then turned into a cloud of dust and dissipated into smoke and dust.

This is the Demon Cave, it has been like this for thousands of years, although it is terrifying, but it also contains a trace of tenderness, as long as you don't touch it, there will be no great harm.

The sky was dark, and I couldn't see my fingers, and in the demon cave, a burst of gloomy and miserable sounds sounded, and the screams of "quack" were non-stop, very similar to the sound of broken bones, and it was very crisp in this night, and it was even more terrifying.

Two points of red light appeared in the demon cave, this red light was like a flame, extremely cold, constantly beating, as if observing everything in the outside world. Gradually, the red light stopped beating and stabilized.

But at this moment, the magic cave was suddenly bright, that is, the red light covered the entire demon cave, making the magic cave at this moment become a bright existence in an instant, but if you look carefully, you can find that the red brightness is not caused by any light, but a little red light, at a glance, you can't see the head at all.

That's the red eyes of thousands!
