In order to avoid an underground river that almost blocked all the way ahead, Qu Wuming had to fly over an extremely large swamp, and after killing many fearless and strange creatures, he finally came to a seemingly desolate area.

As far as the eye can see, there are low sand dunes and craggy rocks everywhere. The sand dunes were all made of black-gray gravel, and under the dim sunlight, there seemed to be a faint black smoke rising up, which was very strange. And on those sand dunes, you can see some strange shapes, strange shapes of black boulders everywhere, like a statue towering in the black sand sea, at a glance you know that they have already experienced countless years of wind and sand baptism, this is what they are today.

This sea of sand is the last barrier between Qu Nameless and Ghost Mingyuan.

Qu Wuming stopped at the edge of this sea of sand and looked into the distance, but he was blocked by the black smoke rising from his vision, and he couldn't see too far away.

"Mingshayuan, it is said that every three days, there will be a Xunfeng wind, rolling the black sand, like a knife like a blade." Qu Wuming remembered that Luo Xingchen had mentioned this to him before, and he already knew in his heart what he might have to face here.

If there were no earth treasures such as the "Falling Star" orb, this would be a very dangerous place, because the wind would make almost the entire sand plain whining sound, like a continuous thunder, hence the name of this sea of sand.

However, at the beginning of the Xunfeng period, ordinary cultivators can barely fly forward in the wind and sand, but if they can't dive deep enough underground within the time of half a burnt incense, or find a suitable place to hide in the rocks, then what awaits him will be nearly ten days of Xunfeng period - in the Xunfeng period, it seems that the black gravel of the entire Mingsha Plain will be swept up by the Xunfeng, whistling and sweeping every inch of space here, down to the bottom of more than ten zhang of the ground, up to a thousand zhang high in the air, no matter where you hide, there will be black sand rolled wildly with the wind everywhere!

Moreover, the most bizarre thing is that the black sand of this Narusha Plains will not be blown away by the Sunwind to other places, as if there is a huge, invisible cylindrical barrier enveloping the Narusha Plain, no matter how high the wind rolls up the black sand, not a single grain of sand will fly outside this barrier.

At the end of the Xunfeng period, all the black sand will slowly fall again with the wind, restoring the appearance of a sea of sand and wasteland at this time, until three days later, the Xunfeng wind rises again and enters the next cycle.

And those craggy and strange rocks in the sea of sand are not as simple as they seem—they look like stones, but they are something that looks like gold and not gold, jade and not jade, and no one knows what they are made of, only that these things look no different from the weathered stones in ordinary deserts, but they are actually extremely hard—even the powerful magic weapons of cultivators in the refining period may not be able to crush them easily.

It is said that cultivators with earth attributes once probed down to a depth of tens of zhang, where they had been piled up to the point where it was almost impossible to walk an inch from the soil.

At present, there are two options in front of Qu Wuming.

One is to cross the Mingsha Plain, and after the Mingsha Plain, it seems that it is not far from the Ghost Mingyuan.

The second is to bypass the Singing Sand Plain, follow the outer boundary of the Singing Sand Plain, find the River Styx and continue to grope upstream, it will take some more time to reach the Ghost Plain.

And the swamp that Qu Wuming crossed before coming here seems to belong to another branch of the River Styx upstream of its current, and if you go back and look for it, you will definitely be able to find the main river of the River Styx.

Qu Wuming looked at it for a moment, calculated the time he had spent in the underworld, couldn't help but sigh secretly, and said to himself in his heart: "It seems that the most secure choice for a detour, but in fact, there is no way to choose at all. Time is limited, how can there be so much time to detour...... If only I could have slapped the map of the underworld in my hand, I wouldn't have known only about the place where Oni Ming Yuan produced soul cultivation crystals. ”

Thinking of this, Qu Wuming sacrificed the "Falling Star" orb and turned into a yellow and clear enchantment to protect himself, and then turned into a ray of light, flew directly in the air, and flew straight towards the depths of the Mingsha Plain.

A moment later, Qu Wuming passed by the vicinity of a strange stone, and on a whim, he suddenly sacrificed a seventh-order immortal sword, and with a little urge, he went straight to the strange stone.

I only heard a crisp sound on the ground, and the fairy sword was like a kitchen knife pierced on the iron plate, sparking a spark, and then stabbing into the black sand with a pop.

Looking at the strange stone again, there was not even a single scratch left.

Qu Wuming couldn't help but gasp, you know, although this immortal sword grade is not the best, but under his own urging, how can Fang Cai's stab be comparable to the casual blow of a cultivator at the peak of the late stage of the Transformation of the Gods or even the Transformation of the Gods, but the strange stone is unscathed!

Qu Wuming couldn't help but be curious, suddenly lowered the light, raised his hand to pick up the fairy sword, looked carefully at the tip of the sword, and found that there was already a small curl on the tip of the sword, and couldn't help but smack his tongue again at the hardness of the strange stone.

"I'd like to see how hard you are!" Qu Wuming's curiosity rose, he came to the strange stone with the hilt of the sword in his hand, and used all his strength to aim at a slender position on the strange stone and suddenly swung a sword.

This sword, without any blessing of mana, is purely the power of Qu Wuming's physical body.

If it is changed to normal, with the strength of Qu Wuming's now strong body, even if this sword is used by an ordinary martial artist, it is enough to cut gold and jade, let alone cut a stone.

However, at this time, the sword was swung out, Qu Wuming only felt a huge shock in his hand, and at the same time that he heard a crisp sound in the ear chakra, the tiger's mouth and wrist suddenly became numb, and before Qu Wuming could take a closer look, the long sword had been broken into several pieces with a bang!

"Huh?!" Qu Wuming couldn't help but shake his hand, threw the broken fairy sword on the ground, and then looked at his tiger's mouth, it had been shattered by two big openings, and blood suddenly flowed out.

Looking at the location where the strange stone was cut, it seemed that there was only a shallow white mark less than an inch long. Qu Wuming squinted his eyes and looked at it carefully, and couldn't help but raise his hand to touch it, and the white mark was easily erased by Qu Wuming - this white mark didn't seem to be a scar on a strange stone at all, but from that sword!

"What a hard stone!" Qu Wuming's mind moved, and a stream of heat gushed out from the dantian, surging along the meridians to the crack of the tiger's mouth, and in a short time, the cracked wound was automatically kneaded together, and the blood suddenly stopped.

Qu Wuming raised his other palm and gently pressed it on the boulder, wanting to take it up with the art of imperial objects, but was surprised to find that this strange stone seemed to have no reaction to his mana and the power of his divine consciousness - if it was an ordinary stone, he could cast a spell after injecting mana to take it up, but this strange stone, it seemed that no matter how much mana he injected, it was like a mud cow entering the sea, and disappeared without a trace.

Suddenly, a black flame rose from Qu Wuming's palm, which was the strongest spell attack that Qu Wuming was currently controlling in his natural state, except for the cormorant's natal flame, the Hongmeng Thunder Fire.

I saw that the Hongmeng Dark Thunder Fire was accompanied by a slight arc, roaring towards the strange stone, and with Qu Wuming's deliberate blessing, the flame slammed into the strange stone with the scorching high temperature, and even the surrounding air was instantly scorched and distorted.

However, after a few breaths of burning, there was no change on the strange rock.

If it was an ordinary piece of bluestone, I am afraid that it would have been burned to ashes by the Hongmeng Thunder Fire at this time!

Qu Wuming was unwilling, and silently recited the magic in his heart, and a gust of wind suddenly appeared beside Qu Wuming, and the wind helped the fire, blowing the Hongmeng Thunder Fire like a jet of fire, and the temperature in the middle of the fireworks suddenly rose several times again.

However, the place where the flames were scorched remained unchanged.

Qu Wuming collected the flames, tentatively reached out and touched the location that had been burned for a long time, and was surprised to find that the tentacles in that place were cold—exactly the same as when he touched it before, as if he had never been burned by the flames.

At this time, Qu Wuming's interest in these strange stone materials had risen to a very strong level, and he even forgot for a moment that the legendary terrifying Xunfeng might blow here at any time.

I saw Qu Wuming take half a step forward, reached out with both arms and hugged the strange stone in his arms, and suddenly tried to pull it out to see, but it didn't matter if he used this force, his feet suddenly stepped into the black sand, but the strange stone did not move at all.

Qu Wuming probed the power of divine consciousness downward, and only then did he find that there was actually a long section under this strange stone, and the further down it became, the thicker it became, and the power of divine consciousness extended to two or three zhang underground, and it was difficult to go deeper, but even if it reached that depth, it still did not find out where the foundation of this strange stone was.

Qu Wuming urged the "Falling Star" Orb and turned into a yellow light cluster to dive down, and was surprised to find that the detection power of the "Falling Star" Orb was also limited in the surrounding black gravel - the effective detection range seemed to be extremely compressed, and it could only barely detect an area of about two or three zhang nearby.

Cautiously went down more than seventy zhang, until the huge stone of the same material below had almost blocked the way to dive, and when it was difficult to go deeper, Qu Wuming found that the foundation of the strange stone was still in the gap of those boulders, and he didn't know how deep it would extend.

Qu Wuming urged the "Falling Star" orb to stick to the stone bed below that seemed to be the bottom of the Mingsha Plain and wandered around for a while, and found more than ten thick stone pillars rising from the underground stone bed like trees, extending straight up, the closer to the ground, the more the surface of the stone pillars will become pitted, strange shapes, and below twenty or thirty zhang from the ground, the surface of these stone pillars is almost flat and smooth.

It seems that the range of the black sand swept by the Xunfeng is at most more than 20 zhang underground. With the "Falling Star" orb in hand, it shouldn't be difficult to avoid the terrifying Xunfeng.

Qu Wuming's heart was a little calm, he couldn't help but rush out of the ground again, flew forward in the sky, flew for about half an hour, and finally saw an expected stone pillar in the distance, and hurriedly flew towards the stone pillar......

It was a stone pillar that had been polished by the Sunwind to a strange shape.

The top of the pillar resembles a mushroom head, about the size of a millstone, and the bottom of the mushroom head gradually becomes slender, thinking that it is a thick wooden stick with a slightly less straight shape. The middle part of the whole stone pillar is the most slender, about the thickness of the mouth of the cup, and then it begins to become thick again, and from a distance, it looks like a conical stone pillar with a huge mallet about a foot long......
