While Xuanjing and the others were talking, Lu Xuan had already come to the bottom of the sinkhole.

Looking up here, a ring of the sky is like washing, and the surrounding waterfalls are pouring like the Milky Way, roaring. And under his feet is the black water vapor, close at hand, this water vapor is five or six miles in a radius, black clouds are churning, thunder flashing, as if there is a dragon churning in the clouds. Between this small world, there was an inexplicable coercion that enveloped Lu Xuan, as if the dragon in the dark clouds could rise into the air at any time, enveloped in thousands of thunders, destroying the world and destroying the world.

Xuanjing said that this black cloud is Xuanfu, and it is also the open source of Xuanfu Mountain. Is it just such a spectacular scenery that is actually a rune array?

Lu Xuan looked at it carefully for a long time, except for feeling that his heart was shaking, he couldn't see anything peculiar.

I had no choice but to continue down the slope, and after passing through the clouds, I really came to the bottom of the sinkhole.

Black clouds overhead and a real lake below. The distance between the surface of Genting Lake is only about ten zhang, but the radius is several miles, forming a wonderful narrow space. Although the black clouds completely blocked the sunlight, there was no sense of darkness between the heavens and the earth.

From the black clouds, hundreds of thunderbolts fell alternately, and although they were radiant, they were silent. The thunder fell on the surface of the lake, and shook the surface of the lake, and turned the lake into clouds, and when the clouds rose into the black clouds, they became part of the black clouds like a river entering the sea.

The river water comes from the outside world, accumulates into a lake, and the black cloud replenishes itself with the lake water, this is actually a small world with its own system, and I am afraid that it is precisely because of this that the black cloud has never diminished after thousands of years.

Lu Xuan couldn't help but admire, if this black cloud was man-made, then the predecessors who shaped this small world in the first place were really ingenious and the Tao was all over the world.

After being obsessed for a moment, Lu Xuan remembered where he came from, looked up at the black cloud, but still didn't find any clues after a while. This is also expected by him, thinking that in the past two thousand years, Xuanfu Mountain does not know how many predecessors have come here to comprehend the mysteries, but they have all returned, and they have only come for a moment or three of a moment, if they can see what is mysterious, it is a fool's dream. He simply put his mind down for a moment and looked around, but he saw many strange things at this glance.

On the pitch-black stone walls and the edge of the lake, there are traces left by predecessors everywhere.

Not far from Lu Xuan's side, there was a black and steep rock, and there was a dent on the rock, which was obviously the trace left by someone meditating cross-legged for a long time. Lu Xuanxin walked over, but saw that the sitting mark was half an inch deep, and in front of the trace, there was some messy handwriting.

"It's useless to look at the clouds, it's useless to look at the water, it's useless to visualize, it's useless for twenty-four years. ”

"Xuanfu, is it a hoax?"

"That's it, I can enter this place, the white horse has passed through the gap, it has been thirty-six years, and the black clouds are still there, in vain. I should go and never pursue this nothingness again. ”

In the end, this person left his name, which was the four big characters of Yixin Taoist.

This turned out to be where Lu Wangshan practiced back then, and Lu Xuan's heart couldn't help but throb a little.

From these words, Lu Xuan could almost understand Lu Wangshan's despair and unwillingness, with his kind of cultivation, after spending decades of time and still not being able to realize the slightest thing from this forbidden land, what could he do? Lu Xuan's heart was a little gloomy, but it was only fleeting. For him, there is nothing difficult in the world, but he is afraid that there are people who have a heart, and he has not made any progress in ten years of practice, and in the end, he has not been forced to find a way?

As I continued to look, there was still a relatively new line of writing on the rock.

"Master, why bother your apprentices? Do you want your disciples to investigate something that you haven't explored for 36 years? ”

"Three years have come, I'm going!"

This handwriting is flying and jumping, don't think about it, it must be left by the mirror. It turned out that he had also practiced here for three years, or three years. Lu Xuan looked at these two lines of words and was a little funny, with the temperament of Xuanjing, he had been practicing hard here for three years, I was afraid that he was going to hold back his troubles.

Leaving this rock, Lu Xuan walked around the bottom of the sinkhole.

The relics of the ancestors can be seen everywhere, and some people have left a lot of experience, but they all look down, but they are all just some speculations, and there are absolutely no clues for reference. Interestingly, after many messages, there are also descendants who have commented and speculated, this circle has gone down, Lu Xuan seems to have witnessed the collision of ideas of many outstanding disciples of Xuanfu Mountain over the past two thousand years, although it did not bring much help to Lu Xuan in the end, but it gave him a deeper understanding of the art of charms, which can be regarded as a great benefit.

He found a flat place at random, sat down cross-legged, and carried the Purifying Heart Mantra.

In the blink of an eye, the Lingtai was clear.

With the experience of many predecessors, Lu Xuan knew that if he wanted to crack the mystery of this Xuanfu forbidden land, he must not be reckless, otherwise it would just be a waste of time. So many Xuanfu Mountain seniors who were proficient in the art of spells returned empty-handed, and with Lu Xuan's qualifications, there was almost no hope. But Lu Xuan has never been the kind of person who retreats in the face of difficulties, and the thoughts in his mind are spinning, thinking quickly.

For today's plan, only think about what others have not thought of, find another way, and maybe there is a glimmer of possibility.

Can the golden needle help him? Lu Xuan carefully realized that the golden needle had not moved at all, and there was no movement.

Lu Xuan had no choice but to give up and find another solution.

This is the simplest and most direct guess, and the vast majority of predecessors did firmly believe in this, but facts have proved that the predecessors who wanted to comprehend the cloud talisman from the black clouds have all failed without exception, and it seems that this road is not working.

Could it be that this Xuanfu was really just a hoax? But for Lu Xuan, there was absolutely no doubt. The golden needle reacted, which proved that there must be a mystery in this forbidden place, but no one has realized it so far.

So where is the mystery?

Talisman...... Black...... Symbol......

I don't know how long it took, and a spiritual light suddenly flashed in Lu Xuan's mind.

Is the Xuanfu character really as Xuanjing said, just plain black?

The black cloud is the black rune, and the black rune is the Xuanfu, which sounds right, but as the open source of the ten thousand laws of Xuanfu Mountain, and it is also the origin of the name of Xuanfu Mountain, is it too hasty to name it just by color?

Lu Xuan's mind was running rapidly, he almost destroyed the 10,000 volumes of books in the library pavilion, with splendid hearts and ideas, only for a moment, four words suddenly came to mind.

Heaven and earth!

The heavens, the mysteries, are lofty and unfathomable, the so-called mysteries and mysteries, the door of all wonders.

Could it be that this mystery refers to the sky?

Lu Xuan subconsciously looked up, but his vision was obscured by the black clouds, but his mind was clear, even if it was invisible to the naked eye, his mind had already flown out of the clouds. Although it was just a flash of inspiration, it made Lu Xuan feel as if he had pryed into something indestructible, and his heart was surging for a while.

One law is universal, ten thousand laws are universal, with this line of aura, the more Lu Xuan thinks about it, the more reliable it is.

When I was just outside, I saw this huge sinkhole, shaped like a huge bowl embedded in the earth, with a wide opening and a slightly smaller bottom. However, if you think about it carefully, doesn't this sinkhole look like a huge eye, looking intently into the void?

Lu Xuanhuo stood up, pacing back and forth, thinking carefully about the messages of those predecessors in his heart, and no one had ever thought about the problem from this angle. This made him itch, and he looked at the middle of the lake in the distance, thinking that if this Xuanzi really represented the sky, and this sinkhole was an eye, then the place in the center was probably the key to looking at the sky.

So Lu Xuan came to the lake in a few steps.

For him, it is not difficult to climb the water, but it is not so simple to dodge those elusive thunder and lightning. He cautiously lifted his steps and stepped on the surface of the lake, took a few tentative steps forward, and was immediately surprised to find that those seemingly terrifying thunderbolts seemed to be hiding from him, and within two feet of his body, everything was calm.

Lu Xuan breathed a sigh of relief, rushed away boldly, and soon came to the middle of the lake.

Lu Xuan looked down and saw that less than half a foot below the surface of the water was a rough rock, with a radius of three or five zhang, and on top of this rock, it was densely covered with traces of meditation by predecessors. It seems that many people have sat and watched here, and Lu Xuan is inevitably a little nervous in his heart, but he doesn't know if his predecessors have tried his conjecture.

Sitting down cross-legged and taking a deep breath, Lu Xuan didn't look at the rolling black clouds overhead, but slowly closed his eyes.

He should be the first person in 2,000 years to be under the black clouds, but he doesn't even look at the black clouds. If those predecessors of Xuanfu Mountain saw this scene, I am afraid that they would inevitably shout that the children cannot be taught, and the rotten wood cannot be carved.

But Lu Xuan had already planned, and as soon as he sat down, he calmed down and looked at the Tianling Acupoint with the method of internal vision.

Since he opened up the Heavenly Spirit Cave several times, every time he stared at the Heavenly Spirit Cave, there would always be a wonderful feeling of connecting with the sky, as if the fugue was too empty, and the unity of heaven and man was indescribable. However, this time it encountered obstacles, and the black clouds above his head seemed to be a swamp, devouring Lu Xuan's divine consciousness and cutting off Lu Xuan's ethereal feeling.

Lu Xuan was not surprised, but blindly meditated and tried to stimulate his divine sense.

A wisp of divine consciousness walked hard through the black clouds, ignoring the inexplicable force in the black clouds, although slowly but firmly drilled upward, like a candle flame fluttering in the wind, burning weakly but persistently. Originally, with the cultivation of a monk in the foundation building period, his divine sense should be weak, but Lu Xuan was born with half a catty of immortal bones, and his divine sense was much beyond ordinary people, and after the golden needle entered the body, after opening up the Heavenly Spirit Acupoint, and after the vicious battle turned into an external demon, his divine sense has made great progress, which can barely persist to this day.

I don't know how long it took, just when Lu Xuan was almost powerless, he suddenly felt that the thick black cloud was finally about to be broken through by himself......
