Chen Mu didn't know that the corpse of Chi Jiao he abandoned was divided up by some grandmasters one after another, even if he knew, he wouldn't care too much, for him, only Chi Jiao's hard work was worth taking, and the others didn't have to be taken in inconvenient circumstances.

He continued to explore the fourth floor, and a few days passed in a flash.

"The leylines are so changing that they can't be found."

Chen Mu is still following the records on the demon skin map, but there is still no harvest for the time being.

It is not necessarily true to say that there are no clues at all, in fact, on this demon skin map, there are some special areas marked as marks, and Chen Mu also found one or two of these special areas.

For example, the ground fissure and magma area that I passed through before is one of the markers.

But the problem is that only that mark is found, and if you continue to explore according to that mark, there are no other clues all of a sudden, and the leylines have changed over time, sinking or floating, and some directions may become opposite.

But.

Just when Chen Mu felt that the clues were slim.

“…… Well? ”

His gaze suddenly moved slightly, a slight discoloration flashed in his eyes, and he cast his gaze in a certain direction in the distance.

Then he walked quickly, and in the blink of an eye, he ran for more than ten miles, and soon came to that place, but he saw a sharp peak on the lonely wasteland, and it was a little inappropriate to say that it was a peak, because it was about five or six zhang high, and the whole body was in the shape of bluestone.

"Allite."

Chen Mu identified this kind of stone, the hardness is extremely high, and it is resistant to moisture and drought, it cannot be corroded by wind and sun, and it often remains unchanged for thousands of years, if it is on the ground, it is one of the minerals worth mining, and it can build a strong city, but it is not a rare thing in the abyss, and it is useless for an existence like him.

It's just that on the demon skin map, the closest marker to the area it depicts is a mountain bluestone forest.

Chen Mu ran back and forth, just looking for the mountain bluestone forest, but he never found it.

“……”

At this time, Chen Mu retracted his gaze and looked behind the raised mountain bluestone, but as far as his sight could see, on the vast wasteland, he couldn't see the second piece of mountain bluestone, as if there was only such a piece here.

"No matter how big the change of the leylines is, it is impossible to strip a piece of mountain bluestone and send it thousands of miles away, since there is a piece here, the mountain bluestone forest should be near here, not very far."

A thought flashed in Chen Mu's heart.

He immediately followed the bluestone center of the mountain, and explored the past piece by piece in the distance, and finally saw a scattered bluestone protrusion in the distance in the south, which was about 20 miles away.

The mountain bluestone forest marked on the demon skin map should be a towering stone forest, but now that more than a hundred years have passed, the earth's leylines have changed, and this mountain bluestone forest has almost been buried underground, with only a few tips exposed.

"The mountain blue stone forest is here, and the location of the map guide should be in the ......"

Chen Mu landed on top of a raised mountain bluestone, looked around, and then closed his eyes slightly, carefully perceiving the nearby heaven and earth environment, and quickly took a deep breath.

Got it!

Here it is!

The mountain blue stone forest marked on the demon skin map grows on a 'stone vein', and the final area recorded on the map is in the stone vein, and when he finds the mountain blue stone forest, he naturally finds the stone vein, which is on the side of the mountain blue stone forest.

"Let me see what is recorded on this map."

Chen Mu set his eyes on the back of the mountain blue stone forest, and then walked a few steps forward, and soon came to the edge of the mountain blue stone forest, and also arrived at the location of the underground stone vein.

It is said to be a stone vein, but it is actually a mountain, a rocky mountain buried underground.

Wow.

Chen Mu raised his foot and stepped on it, and in an instant, the soil surged, and the power of heaven and earth on the soles of his feet was turbulent, and the earth and stone suddenly split to both sides, and the whole person also dived into the ground.

In the fourth layer of this abyss, even he can't calmly escape to the ground, affected by the environment of heaven and earth, he can't easily turn the tangible into the invisible as he does on the ground, and directly escape into the mud and stone as if it were nothing, but to mobilize the power of heaven and earth to open the way.

Soon.

Chen Mu came to an area about seven or eight feet underground.

If it is on the ground, let alone seven or eight zhang, even seventy or eighty zhang is nothing to him, but in the fourth layer of this abyss, just seven or eight zhang underground, the pressure he bears is far from being comparable to two or three hundred zhang on the ground.

After feeling that strong heaviness and oppression, Chen Mu did not forcibly retreat, but closed his eyes slightly, took a few steps forward, and carefully sensed the situation ahead.

Although it is underground, his vision is temporarily useless, but with his perception, he can still perceive the huge stone veins on that side, and its whole body is an underground stone mountain, but the material is chaotic, and almost all kinds of stones are presented.

Among them, there are mountain bluestone and the like.

Even.

Chen Mu roughly perceived that he could feel from it that many jade mines such as 'cold jade' and 'hot jade' were also embedded in it, intricately intertwined, not so much a stone mountain, but more like some kind of abnormal leyline movement, piling up all kinds of stone minerals together, forcibly squeezing them in one place to form an underground stone vein.

Chen Mu quickly approached the stone vein, stretched out his hand to cover the surface of the stone vein, and the tentacle was a cold gold and iron texture, it was a piece of exposed rock iron ore, and it was glowing with a cold feeling, it seemed to be a cold jade ore inside, and it could be judged by a rough perception, and the shape was not small.

However, for Chen Mu today, whether it is rock iron ore or cold jade mine, it is not something he cares about.

"The place marked on the map is inside this stone vein, there should be a cave, but if this stone vein is squeezed and piled up by the power of the leyline, why is there a hole inside?"

The scene of the demon skin map once again appeared in Chen Mu's mind.

But soon he shook his head slightly, there were already a lot of abnormalities between heaven and earth, not to mention that it was in the leyline, and if he finally found the cave hidden in this stone vein, he would know what was inside.

Chen Mu began to explore the past in detail piece by piece along the stone veins.

If it was on the ground, he could forcibly break the stone vein and get through all the way in, but he couldn't do it here, on the one hand, although this stone vein was condensed by various chaotic minerals, it also formed a whole, and the power of the internal leyline was extremely majestic and heavy, and on the other hand, because it was located underneath the abyss, the environment here was even more difficult to shake.

Fortunately.

This stone vein is not extremely large, and the underground part stretches for more than ten miles.

Chen Mu carefully explored the past everywhere, and it took about half a day to finally find an unclosed passage in a certain place, leading to the interior of the stone vein.

"This should be it."

Standing at the entrance of the cave, Chen Mu stared at the inside of the stone vein, and after a cursory perception, he frowned slightly.

With his current perception ability, it is difficult to discern the situation inside this cave, and the distance of perception is no more than ten zhang at most, and then it comes to an abrupt end, and there is no clear perception.

But.

Today's Chen Mu is also a master of art and bold.

No matter what was in this cave, he was not so afraid now, even if he bumped into a ninth-order heavenly demon, with his current strength, it was enough to fight with it, and there were very few situations that could threaten him after all.

Trample.

After Chen Mu took a step forward, he stepped into the cave.

As soon as Fang entered the cave, he immediately felt something different.

If the oppression from the abyss covering him outside the cave, on the outside of this stone vein, was very strong, then when he stepped into the cave, the oppression from the abyss immediately weakened.

This also surprised Chen Mu slightly.

Because since he came to the abyss, he had never felt this way, and the oppression from the abyss always became stronger as he went deeper, and it never diminished anywhere, but this place was completely different.

"No wonder this place is so weird, and the oppression from the leylines is so strong, that it has never destroyed this cave and squeezed the stone veins into a substantial piece...... What is in this cave that can resist the oppression of the abyss? ”

Chen Mu stared into the depths of the cave.

As far as his eyes could see, it was pitch black, and he couldn't see any light, and he couldn't tell what was inside.

After a short period of silence, Chen Mu continued to go deeper into the cave, and as he went deeper, the sense of oppression from the abyss that shrouded him became weaker, until after twenty or thirty zhang deep into the cave, the oppression disappeared completely!

It was as if he was no longer in the abyss, but had returned to the earth.

So.

Chen Mu took a few more steps inside, but the world in front of him suddenly opened up.

But when I saw the top, I don't know when it was no longer the rock wall of the stone vein, but a dark and unknown nothingness, and there seemed to be countless fine white marks at the end, in all directions, as far as the eye could see, it was also a void scene.

And Chen Mu's whole person stood at the edge of a huge stone layer that stretched for about several miles at this time.

Look down.

I saw that this huge rock that stretched for several miles, and there was also a void below it, and it was all floating in mid-air!

Looking further ahead, you can see that in the pitch-black void, there are a large number of stones floating in the air, and the large chunks of them stretch for miles, like a small island floating in the sky.

"This is ......"

A hint of emotion finally appeared on Chen Mu's face.

Although he entered this place through the passage of the underground stone vein, he could be sure that this place was no longer in the stone vein, not even in the abyss, so he would be completely isolated from the oppression from the abyss.

Cave sky!

It's a small cave!

Although it exists in the center of the underground stone vein, it is actually another space, and although the radius is not very large, it at least stretches for dozens of miles, much larger than the stone vein outside.

Regarding this kind of cave world, Chen Mu had also seen a description in the classics, but there was only one sentence.

- Dongtian, rare in the world.

"Cave Heaven, it turns out that what was recorded on the demon skin map is a cave land."

A glimmer of light flashed in Chen Mu's eyes.

A stone vein that is only more than ten miles in circumference, but the interior can accommodate dozens of miles of space, he completely let go of his own perception, carefully perceiving the situation inside this cave, and for a while he only felt that there were mysteries everywhere.

Turn Sumeru into mustard seeds, and contain heaven and earth in square inches.

The artistic conception of Qiankun that he has cultivated, in charge of the eight phases of heaven and earth, is almost impossible, but it can't affect the essence of the void, even if he goes all out, and fights hard with Qin Mengjun like Qin Mengjun, he can only make a few cracks.

"Speaking of which, most of those Cave Heaven Spirit Treasures, such as the Qiankun Pot, are similar to this place."

Chen Mu sensed the environment of this cave, and couldn't help but think of the treasure Qiankun pot recorded on the genealogy of the Great Xuanling Army, which was claimed to contain Qiankun in the pot, but this was obviously an exaggeration.

Staring at the emptiness around him, the first thought that came to Chen Mu's mind was whether he could get a piece of his own, like the 'Qiankun Pot', which he had long been eager to see.

But this cave is also very problematic.

If this square stone vein is regarded as a 'Qiankun pot', then this 'Dongtian Spirit Soldier' is a little too big!

No matter how small the internal space of the Qiankun pot is, its body is very small after all, and this square stone vein stretches for more than ten miles, it is impossible to carry it out as a cave spirit soldier to use, it is meaningless.

"Speaking of which, all spirit soldiers have a process of 'refining', but the Qiankun pot has never heard of how to refine, could it be that this refining process is ......"

Chen Mu carefully looked at this square cave sky, revealing a look of contemplation.

He suddenly became suspicious.

Was the Qiankun pot once such a huge stone vein, and then through continuous refining and condensation, its body became smaller and smaller, until it was finally refined into a 'Qiankun pot'?

If this is the case, it is obviously not good for him, not to mention that he does not know much about the method of refining, even if he understands it very well, if he wants to slowly refine this square stone vein, it is by no means a day's work, and it is obviously not something that can be done in a short period of time.

But that's normal.

If it can be easily refined, there will not be only one Qiankun pot in this world, and that Qiankun pot may even be repeated by several generations before it is finally refined.

Because he had never come into contact with the cave heaven and had never seen the Qiankun pot with his own eyes, Chen Mu only knew a little about it, and after frowning and thinking for a moment, he temporarily put aside the distracting thoughts, planning to carefully explore this cave heaven first.

This Fang Dongtian is not small, but it is not big.

There were only seven or eight large 'small islands' floating in the air in a radius of about dozens of miles, and Chen Mu only took a moment to walk around these places, but there was nothing else to gain.

Compared to the abyss, this cave is too narrow, and it is normal that it can't breed any rare spiritual objects, not to mention that even if there are really rare spiritual objects accompanying it, it has already been taken away by the person who refined the demon skin map, and it is impossible to leave it here.

Only this cave itself, the other party can't take it away.

Perhaps because of this, the other party refined a demon skin map, recorded this prescription bit, and left it for other purposes in the future, but I don't know what happened, so that this demon skin map went through several tosses and turns, and finally fell into his hands.
