The killing aura was like a cold demon flow, not to mention the young demon who was closer, and even Yun Yi outside the valley couldn't help but tremble."
It seems to be the breath of the formation."
Yun Yi's eyes were shining, and he looked at the cave that suddenly appeared without blinking, he who had cultivated the Yuan Array Heavenly Book, he had an extraordinary perception of the formation, the sudden appearance of the killing aura, with a strong formation aura, according to Yun Yi's thoughts, if nothing else, the source of the killing qi may be a life-killing formation."
These demons came prepared, so it can be seen that they already knew that there were treasures here, so after coming from the abyss world, they immediately found this place."
Black Wind said."
I don't know what kind of baby it is, I'm really looking forward to it."
Yun Yi smiled on his face, the treasure that can attract the demon masters of the abyss world must not be ordinary, and if nothing else, the treasure in this must be related to the demon race.The young demon put away the grinding disc in his hand, and a layer of black magic power appeared on his body, and with a wave of his hand, he led the five demons towards the entrance of the cave with a fierce aura.Seeing this, Yun Yi couldn't stay any longer, there must be treasures in this cave, there is no doubt about this, since Yun Yi is here, it is naturally impossible to watch here in vain, if the treasures inside are taken away by the devil, wouldn't it be a big loss."
Black Wind, do you remember the last time you cast your invisibility technique?"
Yunyi asked."
Well, I'll do it now, but it can't last too long."
Hei Feng nodded, and immediately cast the invisibility technique, Yun Yi and Hei Feng quickly swept towards the entrance of the cave under the invisibility technique.Yun Yi has the method of wandering freely, coupled with the strong power of the soul, he can not show any breath, and now with the help of Black Wind's stealth technique, even in the face of the master of the Eight Heavens of the First Line, he can be foolproof.What's more, it was impossible for the young demon to have imagined that someone would appear here and dare to enter the cave.Yun Yi arrived near the entrance of the cave, the fierce killing aura, like a cold blade, cut the skin painfully, that is, a pervert like Yun Yi, if he was replaced by other spiritual cultivators of the first line of heaven and one heaven and two heavens to come here, I am afraid that he would not even be able to resist this killing aura, let alone enter the cave inside."
Let's go, go in and have a look."
Yun Yi withstood the murderous aura and entered the cave.The scene in the cave has changed drastically, this is a completely different world, there is a space the size of a hundred zhang, and there are dim air currents everywhere, and the aura of slaughter permeates every corner.Several demons stood in front of them, looking at the center of the cave with terrified eyes.There was a black altar two feet high, and the altar was terrifying and gloomy, and it was actually an altar made of countless bones.Among those bones were huge skulls, long arm bones, and human bones.The whole altar is filled with the breath of death, evil energy, death energy, resentment, all kinds of negative qi filling the entire cave, giving people a creepy feeling.And what really attracts people is not the eerie altar, but the rows of strange black swords on the altar.Look at those war swords, they are as black as ink, there are a total of ninety-nine eighty-one, and each war sword exudes endless demonic energy, and the evil aura is soaring to the sky.Eighty-one war swords, exactly the same, as if carved out of a mold, even each rune on it is the same, the breath is connected, so many war swords are fused together, and they can exert an incomparably imaginary power."
My God, these battle swords, each of them is not lower than the Reverse Flame Xuanqi, and they have all reached the peak of the Yuan level, second only to the existence of king-level soldiers."
Yun Yi almost didn't exclaim, the value of these eighty-one swords was simply unimaginable."
It's amazing, I didn't expect that there is a peerless sword formation hidden here, it must be left by the master of the demon clan, no wonder it will attract people from the demon clan."
Black Wind's eyes lit up, and his gaze fell on the altar without blinking."
Do you know this sword formation?"
Yun Yi asked, after all, he had only been able to obtain the Yuan Array Heavenly Book for a short time, and his knowledge of the various great arrays between heaven and earth was far inferior to that of Black Wind, especially such a demon array."
This is the demon clan's ninety-nine Asura sword array, with ninety-nine eighty-one swords of the same root and origin, this sword array uses the mystery of ninety-nine to one, divided into nine directions, each direction of nine swords, complement each other, can be transposed, this sword array in front of you is supported by a terrifying altar, making the ninety-nine Asura sword array more murderous, more powerful, these swords together to exert a power, has surpassed the king's soldiers, unceremoniously said, If a first-line heaven peak master could perfectly unleash the power of the Nine-Nine Asura Sword Formation, it would be enough to trap a Spirit King master. ”The black wind's eyes were shining, and he said word by word: "Boy, if you can put away this sword formation and comprehend it, it will add an unimaginable strong hole card, the level of these swords is the peak of the yuan level, and there is a strong room for progress, there is hope to promote the existence of the king's soldiers in the future, you just imagine, the ninety-nine asura sword formation formed by the ninety-nine eighty-one king's soldiers, how terrifying will it be." ”Black Wind's words made Yun Yi's heart even more restless, this is simply a great treasure, Yun Yi's hands are itching when he sees it, the power of this sword array is really terrifying, if he gets it in his hand, it will be an unimaginably strong hole card.However, Yun Yi also knew that it was by no means easy to collect the Ninety-Nine Asura Sword Formation, not to mention the difficulty of collecting the Sword Array itself, it was impossible for Yun Yi to take the Sword Formation away with these powerful demons in front of him alone."
Look, these demons are ready to make a move, if the sword array lets them take it away, won't we be happy in vain."
Yun Yi saw that the young demon began to move, and his heart immediately became unsettled."
Don't worry, just with them, it is impossible to collect this sword formation, if it is the demon king master of the demon clan, maybe there is no problem, this is also what I don't understand, since the abyss world is a gathering place for demons, there should be a demon king master, the ninety-nine Asura sword formation is still very important for the demon clan, it is enough to be worthy of the demon king's shot, how can only these few come."
Hei Feng was a little puzzled, but he was not worried that the young demon would take the sword formation away, because he knew the sword formation extremely well, and if he wanted to take the sword formation away, he had to have the strength to break the formation."
I heard that in the ancient period, the demon race was defeated, and was driven to the edge of the Western Regions, suppressed by the Buddhist sect in the Western Regions, how come there are also demons in the Eastern Wilderness, this abyss world, I don't know what's going on?"
Yun Yi was puzzled, but this was not a question for him to think about, he knew that since the abyss world was under the Eastern Wilderness, even if there was a demon clan here, it would definitely not be too powerful, otherwise, the Eastern Wilderness would have been at peace for a long time.Yun Yi's current mind is on this sword array, as for the existence of the abyss world, it is a good thing for him, at least it gives him a good opportunity to practice.
