Unparalleled War Emperor

The chilling aura was like a burst of cold demonic current. Not to mention the young demon who was closer, even Yun Yi outside the valley couldn't help but tremble.

"It seems to be the breath of the formation."

Yun Yi's eyes sparkled, and he stared at the sudden appearance of the cave without blinking. He had practiced the Heavenly Book of the Yuan Formation and had an extraordinary perception of the formation. The sudden killing aura was accompanied by a strong formation. According to Yun Yi's thinking, if nothing unexpected happens, the source of the killing aura may be a life-threatening formation.

"These demons came well prepared. It can be seen that they already knew that there was a treasure here, so they found it immediately after arriving from the abyss world."

Black Wind said.

"I don't know what kind of treasure it is. I'm really looking forward to it."

Yun Yi had a smile on his face. The treasure that could attract the demon masters from the abyss world must not be ordinary, and if nothing unexpected happened, the treasure inside must be related to the demon clan.

The young demon put away the millstone in his hand, and a black magic shield appeared on his body. With a wave of his hand, he led the five demons towards the entrance of the cave, facing the murderous aura.

Seeing this, Yun Yi couldn't stay any longer. There must be treasures in this cave. There is no doubt about this. Now that Yun Yi is here, he can't watch here in vain. If all the treasures inside are taken by the devil, If you leave, wouldn't it be a big loss?

"Heifeng, do you still remember the invisibility technique you used last time?"

Yun Yi asked.

"Well, I'll use it now, but it can't last too long."

Heifeng nodded and immediately used the invisibility technique. Yun Yi and Heifeng quickly flew towards the entrance of the cave under the invisibility technique.

Yun Yi has the free-traveling movement technique, coupled with the powerful soul power, he can not show any breath. Now with the help of Hei Feng's invisibility technique, he can be foolproof even when facing the masters of the eighth layer of the sky.

More importantly, it was impossible for the young demon to think that someone would appear here and dare to enter the cave.

When Yun Yi arrived at the entrance of the cave, the fierce killing aura was like cold sharp blades. The cut skin was painful. That is to say, for a pervert like Yun Yi, if he were replaced by other spiritual cultivators from the first line of heaven, the first level of heaven, and the second level of heaven, Here, I'm afraid I can't even resist the murderous aura, let alone enter the cave.

"Let's go in and take a look."

Yun Yi braved the murderous atmosphere and entered the cave.

The scene inside the cave changed drastically. It was a completely different world, with a space of a hundred feet in radius. There were dim airflows everywhere, and a chilling air permeated every corner.

Several demons stood in front, looking at the center of the cave with horrified eyes.

There is a two-foot-tall black altar here. The altar is terrifying and gloomy. It is actually an altar made of countless corpses piled up.

Among the bones, there were huge skulls, long arm bones, and human bones.

The entire altar is filled with the aura of death, evil spirit, dead energy, resentment, and all kinds of negative energy that fills the entire cave, giving people a creepy feeling.

But what is really attractive is not this eerie altar, but the rows of strange black swords on top of the altar.

Look at those battle swords. They are as black as ink. There are ninety-nine and eighty-one in total. Each battle sword exudes endless demonic energy, and the evil energy reaches the sky.

Eighty-one war swords are exactly the same, as if they were carved from the same mold. Even every rune on them is the same, and their auras are connected. When so many war swords are fused together, they can exert unparalleled power.

"Oh my God, the level of each of these war swords is not lower than that of Niyan Xuanqi. They have all reached the peak of Yuan level and are second only to king-level warriors."

Yun Yi almost didn't scream out in surprise. 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 have been left by a master of the demon clan. No wonder it attracts people from the demon clan."

Hei Feng's eyes were bright, and his gaze fell on the altar without blinking.

"Do you know this sword formation?"

Yun Yi asked, after all, it was only a short time since he obtained the Heavenly Book of Yuan Formation, and his knowledge of the various formations in the world was far inferior to that of Black Wind, especially such a demonic formation.

"This is the Demon Clan's Nine-Nine Asura Sword Formation, which is made up of ninety-nine and eighty-one swords of the same origin. This sword formation makes use of the mystery of the Nine-Nine Return to One, and is divided into nine directions. Each direction is divided into nine directions. The nine war swords complement each other and can change positions. The sword array in front of you is supported by a terrifying altar, making the Nine-Nine Asura Sword Array even more murderous and powerful. The combined power of these swords , has surpassed the King's Soldier, and to put it bluntly, if a master at the top of the line can perfectly release the power of the Nine-Nine Asura Sword Formation, it is enough to trap a master of the Spirit King to death. "

Hei Feng's eyes shone brightly, and he said word by word: "Boy, if you can put away this sword array and understand it, it will add an unimaginable powerful trump card. The levels of these swords are all Yuan level. It is at its peak, and has great room for improvement. It is possible to be promoted to the King's Arms in the future. Just imagine how terrifying the Nine-Nine Asura Sword Formation formed by the ninety-nine and eighty-one King's Arms will be."

Heifeng's words made Yun Yi's heart become even more agitated. This was simply a huge treasure. Yun Yi's hands felt itchy just looking at it. The power of this sword formation was really terrifying. If he got it in his hands, then It will be an unimaginably powerful trump card.

However, Yun Yi also knows that it is not easy to collect the Jiujiu Asura Sword Formation. Not to mention the difficulty of collecting the sword formation itself, it is impossible for Yun Yi to use the sword with these powerful demons in front of him. Take away the array.

"Look, these demons are ready to take action. If the sword array is taken away by them, wouldn't our happiness be in vain?"

Yun Yi saw the young demon starting to make some moves, and his heart immediately became uneasy.

"Don't worry, it's impossible for them to collect this sword array. If the masters of the Demon King of the Demon Clan come, there may be no problem. This is what I don't understand. Since the abyss world is a gathering place for demons, there should be There are masters of the Demon King, and the Nine-Nine Asura Sword Array is still very important to the Demon Clan, and it is worthy of the Demon King's action. Why would he only let these few come? "

Heifeng was a little puzzled, but he was not worried that the young demon would take away the sword formation, because he knew the sword formation extremely well, and if he wanted to take the sword formation away, he must have the strength to break the formation.

"I heard that in ancient times, the demons were defeated and were driven to the edge of the Western Region. They were suppressed by the Buddhists in the Western Region. Why are there demons in the Eastern Wasteland? What's going on in this abyss world?"

Yun Yi was puzzled, but this was not a problem he was thinking about. He knew that since the abyss world is under the East Barren, even if there is a demon clan here, it must not be too powerful. Otherwise, the East Barren would have been destroyed long ago. Peace.

Yun Yi's current thoughts are all on this sword formation. 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.
