The emotion of fear permeates the hearts of everyone, and this invisible crisis is the crisis that makes people really afraid. With a slight sound of the wind, a human head quietly fell to the ground, what kind of thing is this?

The four sect masters and Yi Yunfei, including everyone, had a solemn expression, they had already imagined countless scenes before entering here, and had expected all kinds of hidden weapons and formation prohibitions, but the only thing they didn't expect was this situation.

"What is this? Is it a prohibition?"

"What kind of prohibition is so powerful, and can take people's lives without a word?"

Many people whispered, and at this time, another gust of majestic wind blew, and several timid disciples felt a trace of coolness on their faces, and screamed loudly in fright, their hands grabbing indiscriminately in the place where the wind was blowing, and their eyes were full of despair.

No one died, it was just an ordinary wind. But at this moment, the grass and trees were already soldiers, and those disciples were not injured by this breeze, but were scratched by their own hands on their faces and bodies.

I can't see it, I can't touch it, but it's like a moat, blocking everyone's eyes and pressing on everyone's hearts.

Yi Yunfei thought for a moment, took out a robe, walked to the front of the line, shook his hand, and threw it over the corpse of the disciple who had died. After the robe was thrown, it was stirred up by the energy, spread out in the air, and flew over with a spin.

Everyone's eyes lit up, and they immediately understood Yi Yunfei's intentions, and looked at the robe flying in the air with some admiration.

There was still no sound, even the four sect masters, the divine thoughts were released without reservation, and they only felt a slight sound, and the robe turned into two in the air, and then floated back and forth, shaking and slowly falling.

"It seems that this is the only place that has it!" Wang Jingnan seemed to breathe a sigh of relief and said slowly.

But before his words fell, the truncated robe seemed to be picked up by a breeze at the moment when it was about to hit the ground, drifting a distance of about a foot forward, and then something happened that made everyone's scalps tingle.

The fluttering two sections of robes, as if they were being cut indiscriminately by some angry little girl with scissors, were shattered in disbelief by everyone, broken into silk, into wisps, into pieces.

......

......

The silence, the silence that was suppressed to the extreme, the light of the torches swaying, making everyone's faces look uncertain, everyone looked at each other, and even their breathing became much lighter unconsciously. It was as if in the darkness that could devour everything, there was a bloodthirsty devil who made everyone dare not be alarmed.

Yi Yunfei's face turned a little pale, but he was not afraid, but took out a few shirts from the ring again, his hands kept shaking, and threw them forward, countless clothes were like figures, flying towards the top of the abyss one after another.

This time, it was no longer silent, but finally there were some sounds, these sounds were those that were unexpectedly torn, dense, crisp, as if a long time had passed, but it was only a blink of an eye, and the clothes had not accidentally turned into fragments, as if they were colorful snow, drifting and falling, reflecting the coldness of everyone's hearts.

Yi Yunfei didn't continue, but slowly closed his eyes, and his divine thoughts slowly advanced forward, as if he was moving forward in the mire, and the speed of his divine thoughts was very slow. The divine thoughts were scattered slightly, floating in the Dark Sect, searching.

I saw it, I finally saw it, those winds that couldn't be seen by the naked eye, under the observation of the gods, seemed to be a snowy light, dazzling, so dazzling that people didn't dare to look at it directly. Sharp, decisive, a trace of divine thought was cut by this light, and then cut, as if there were countless blades scraping in his mind, and the severe pain made Yi Yunfei's face pale.

But his expression was a little excited, he felt it, it was a sword, countless knives. These swords wandered in the dark, lonely and resolute, fierce and indifferent. Yes, the sword is the sword, how can there be so many emotions? But Yi Yunfei can clearly feel that these swords no longer seem to be lifeless rays, but vivid and cold lives, they are telling, roaring, and attacking.

Chopping, piercing, wrapping, wrapping, every knife looks so clear, so slow, so distinct, but the movement of the divine mind is still impossible to dodge. It's as if a huge mountain is coming down towards you, very slowly, very clearly, and you still can't dodge, no matter how hard you try to escape, and if you go deep into your arms to block it, it will not help.

"What kind of sword technique is this? Can actually let this aura exist here for tens of thousands of years, and still have such power? When this knife was just cut down, how amazing was its power?"

"Sect Master Yi, what have you discovered?" Sima Hong looked at Yi Yunfei with concern and asked softly.

"It's a knife, the countless swords left behind after a peerless powerhouse slashed it down, and it won't be dispersed for thousands of years!" Yi Yunfei exhaled lightly and said slowly.

Although everyone couldn't believe it, they didn't raise any questions, after all, except for the explanation proposed by Yi Yunfei, no one else had been able to find anything! However, after hearing Yi Yunfei's explanation, many people had already retreated, and the danger of this trip had exceeded their expectations, although only one disciple had lost his life for the time being, but everyone knew that even if more people died, they would not be able to crack the level in front of them, which was beyond their understanding.

The weapon in the hand uses the Xuan power to release the invisible aura, which is a compulsory course at the beginning of entering the Xuan realm, of course, not everyone can do it, and it depends on the characteristics of the exercises practiced. The sword cultivator's advantage in this regard may be more obvious. These sword qi and sword qi are not absolutely formless and colorless, and the divine mind can still sense that aura when cultivating to a certain extent. However, once these breaths are released, no matter whether the result can hurt people or not, the final result will still dissipate in the vast world, and the time of existence is very short.

But Yi Yunfei said at this moment that the wind flowing away from this dark moat was a knife wielded by a strong man ten thousand years ago, after such a long period of erosion, it could still have such power, how could they break it?

"Let's take a closer look around, maybe I'm wrong, I hope it's a ban or something, and there's a little hope of cracking it. If my prediction is correct, I'm afraid I'm really going to return in vain this time!" Yi Yunfei sighed and shook his head gently. This time when I entered the underground space, there was always a strange aura in everyone's hearts, although nothing earth-shattering happened, just the death of a disciple of the Famous Sword Sect, but everyone felt that this trip was very dangerous.

"Okay, that's the only way!" Wang Jingnan also sighed deeply and arranged for his disciples to disperse and explore. And the line not far in front of him, although invisible, is the most deadly, and no one dares to approach it in the slightest.

Yi Yunfei worked hard to recover his divine thoughts, he always felt that the countless scattered swords seemed to have an inexplicable connection with himself, although every time he cut off his divine thoughts, he would be struck by lightning, and his mind would turn over. But every time he was cut off, he felt that his divine thoughts seemed to have established some kind of connection with those swords.

"There's another hole here!" A surprised voice came from the Dark Sect not far away, and a disciple of the Quyang Sect was standing at the entrance of a person who had just passed through with a look of surprise and waving his arms towards everyone.

Almost everyone quickly ran towards the entrance of the cave, after all, the range of the torch lighting is limited, and the range released by most people's divine thoughts is not large, so they can only focus their attention as much as possible on exploring the road ahead, who would have expected that at this moment, under the exploration, a new entrance was found on the side?

Everyone had a sense of brightness, and their faces were full of joy. However, Yi Yunfei didn't move, he still sat cross-legged in front of the abyss like a giant mouth, thoughtful!
