Ten days later, in the sea of ​​willows, three streams of light quickly jumped into the void and walked towards the northern part of the outer demon star, which was the territory of the Old Ancestor Dust Bone.

According to the sword demon and Bi Liu, the ancestor of the Dust Bone practiced the "White Bone Demon Thunder" and would go out to find spiritual bones to practice every time. This was the last time for them to ambush. If they missed this opportunity, they would probably only be able to find him when the Dust Bone Ancestor was promoted to the fourth level of the Immortal Thunder, and at that time, everything would be too late.

The world is vast, and the land in the north of the outer demon star is bitter and cold, the earth is withered, the forest is sparse, and large wastelands are continuous and endless, and there is no end to see. This is a dead land and a forbidden area for life. Even demon cultivators in the Thunder Infant Stage rarely come here.

However, such a place has no problem with the three ancestors of the External Demon Star. Although it is desolate, it is full of infinite magic. Occasionally, when a breeze blows, a sound of ghosts will sound. It seems that this place gathers all the dead lives on the External Demon Star here, making it an alternative hell.

It is rumored that this place was caused by the formation arranged by the Heavenly Demon Sect, gathering thousands of yin energy to form a place of Yin death. However, as the Heavenly Demon Sect gave up the external demon star, the formations here were constantly declining, and the yin energy here was also getting smaller and smaller. If hundreds or thousands of years were spent, this place would definitely return to normal.

But these were a bit too early for the three ancestors to consider. In such a hell land, the three ancestors were like fish in water, absorbing the yin attribute thunder power in it, strengthening themselves, and eventually dominating one side, causing the external demon star to form a three-legged situation.

Of course, the cultivation of the three ancestors is high and low, the highest of which is the Old Bone Ancestor. His cave is far away from the White Bone Cave in the north. This White Bone Cave is extremely north and is only hundreds of miles away from the extreme north. There is a roar of Yin Feng and is protected by terrifying Yin Spirits all year round, which is difficult for ordinary people to enter.

In the White Bone Cave, there are countless white bones, including some powerful cultivators and the spiritual bones of thunder beasts. The Bone Ancestor Killer Bone grabbed the spirituality from these Bones, taking the bones as the root, and finally made the reputation of the Bone Ancestor Killer Bone.

The sword demon and Bi Liu's cultivation is slightly inferior. Their cave is farther away from the extreme north and will not easily step into the extreme north in normal times, because it is the territory of the old ancestor of the dry bones. If they step into it, it may trigger a war.

The Demon Cave is a dangerous place in the northern part of the Demon Star. It is rumored that extremely powerful creatures were buried here, and strange changes have occurred. A ghost tide will appear every ten days and half a month. At that time, infinite ghosts surge out of the Demon Cave, like a tide, red and black everywhere, which is particularly terrifying.

In this ghost tide, there are many powerful ghosts. They were all cultivators with strong cultivation during their lifetime, thunder beasts. Even if they lose their spiritual intelligence after death and turn into ghosts, their instincts are still there, and coupled with the infinite Yin power they possess, even cultivators in the thunder infancy stage may fall.

Therefore, on the external demon star, whenever when talking about the demon cave, every demon cultivator will change color. This shows that the terrifyingness of the demon cave is, even if it is a fierce demon cultivator, it is extremely afraid.

But although this demon cave is terrifying, sometimes surprises will occur. When the ghost tide occurs, the demon cave not only releases endless ghosts, but also may spew out some thunder soldiers, spiritual bones and other things.

These are all cultivators buried in the demon cave, left by the thunder beast. After thousands of years of experience, you can imagine what powerful things these are. Therefore, even though you know that the ghost tide is very dangerous, every time the ghost tide bursts, many cultivators with strong self-cultivation and cultivation will arrive in the demon cave, waiting for the ghost tide to arrive, hoping to get some treasures.

The Ancestor of the Killer Bone is a frequent visitor. Because the spiritual bones required to practice the "White Bone Demon Thunder" are very large, and the quality requirements for spiritual bones are very high when practicing to the depths. Therefore, the Ancestor of the Killer Bone made his mind into the demon cave. Basically, every time the ghost tide bursts, there is a shadow of the Ancestor of the Killer Bone, which is also the biggest basis for the Sword Demon, Bi Liu is sure that the Ancestor of the Killer Bone is here.

"Brother Yu, there is a demon cave ahead. The environment here is dangerous and the wind is rolling. You have to be careful when you are here for the first time." In the void, the sword demon reminded carefully that dozens of miles ahead of him, a cave with a radius of hundreds of feet was presented in front of Lei Yu.

This cave is dark, gloomy, terrifying, and can't see clearly. Even if the divine mind radiates out, it will be swallowed up. It seems that there is something strange in this cave that can block the divine mind's visit.

"Whoo!" The dark wind blew and came out of the cave. The cave looked like a passage to the Nine Nether Hell, gloomy, and some miserable sounds of ghosts screaming, floating in the sky. Even during the day, it still made people feel trembling.

This is the demon cave, a place with demons that is strange and unfelt. With the demon cave as the center, it is pitch black within a radius of thousands of miles, as if this land was cursed by something, and there is no other color except black.

The mountains and rivers are vast, but they are withered and have no vitality. The demon cave seems to be absorbing the vitality within a radius of thousands of miles, making all life disappear here and become a barren land.

Lei Yu frowned slightly, and a sense of awe-inspiring feeling rose in his heart. Logically speaking, this place is a dark place, which is like a fish in water for him who is practicing the "Nine Nether Yellow Spring Thunder", but now he feels like he is stared at by a beast, and his every move falls into the other person's eyes, and perhaps it will become the other person's mouth food in the next moment.

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

"Thank you, Brother Shi, for your reminder!" Lei Yu said, pressing down on his uneasiness. After ten days of getting along, he and the sword demon and Bi Liu are no longer unfamiliar with each other, and have changed a lot in their names.

"Haha, this is the first time Brother Yu has come to this demon cave and doesn't know much about everything here. In this way, you will follow Shi and you will never suffer any loss." The sword demon laughed, paused in the void, and immediately headed towards a mountain below.

Naturally, Lei Yu did not doubt it and turned into a stream of light and left. The same was true for the Biliu, and soon settled on the top of a mountain.

"Brother Yu, as you can see, this huge cave in front of you is the Demon Cave. It is rumored that an extremely powerful creature was buried here, which led to such a change. Usually, the Demon Cave is not very irritable. Only when the ghost tide is reached will the Demon Cave be truly opened. At that time, this Demon Cave will be like the Nether Gate, and endless ghosts will gush out of the Demon Cave."

"At this time, the old ancestor of the dry bones will definitely come. We just need to wait for the rabbit. Even if we can't kill him, it will be enough to severely damage him."

A trace of hostility appeared in the sword demon's eyes. It was obvious that he had already thought of getting rid of the old ancestor of the dry bones, and he had already inquired about everything about the old ancestor of the dry bones.

"Brother Yu, this time, killing the Old Ancestor Dust Bone is mainly based on fellow Daoist Shi and I. You only need to assist me, and you don't need to take too much risk. I set up the "Bi Liu Formation" around half a year ago. Although this formation does not have any attack power, it is extremely hiding. Even the Old Ancestor Dust Bone may not be able to discover it in a short period of time."

"At that time, you just need to hide in the 'Bi Liu Formation', listen to my orders, and with the strength of the three of us, you will definitely succeed."

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

"Thank you fairy!" Lei Yu said with peace of mind, as if he was relieved. Lei Yu's actions fell into the sword demon, Bi Liu's eyes. The two of them looked at each other, and they both saw a smile in each other's eyes.

Although this "Bi Liu Formation" can be hidden, it is also a trap. If the two lose to the Old Ancestor of the Bone, they can expose Lei Yu and buy time for the two to retreat, and even push everything on Lei Yu to make him a scapegoat.

"Hmph, if you want to plot against me, it depends on whether you have the ability!" Lei Yu snorted coldly, pretending not to see the movements of the two of them, and entered the "Bi Liu Formation" alone. He is a "trump card" and needs to be used at the most critical moment.

The earth is vast and dark, and it is impossible to distinguish between the day and the night. A bright moon slowly rises into the sky, appearing faintly in the thick clouds and mist. The pale moonlight shines down, and a cool light appears on the black earth, which looks very strange.

The sound of ghosts kept ringing, and the night here was more like a ghost realm. The cold evening breeze blew, stirring a piece of black smoke and dust, which even spread the sounds further away, so that the territory within a radius of thousands of miles centered on the demon cave was shrouded in a terrifying atmosphere.

The demon cave is still dark and sweet, and I don’t know where it leads, as if it is really connected to the Nine Nether Hell. Occasionally, one or two ghosts spewed out of the demon cave, walked on the black earth, with a confused expression and no intelligence, and then turned into a piece of dust and dissipated into smoke and dust.

This is the Demon Cave, which has been like this for thousands of years. Although it is terrifying, it also contains a hint of tenderness. As long as you don’t touch it, there will be no major harm.

It was dark and I couldn't see my five fingers. In the demon cave, there were waves of cloudy and miserable sounds, "Gaga" kept shouting, very similar to the sound of a broken bone. It was extremely crisp in this night and even more terrifying.

Two red lights appeared in the demon cave. The red light was like a flame, extremely cold and constantly jumping, as if observing everything outside. Gradually, the red light stopped jumping and stabilized.

But at this moment, the demon cave suddenly became bright, and the red light filled the entire demon cave, making the demon cave a bright existence in an instant. But if you look closely, you can find that the red light was not caused by some light, but a little red light. At first glance, you can't see the head at all.
