Then Li Mo suddenly stopped walking, and three feet in front of him, the sharp stones on the top of the cave collapsed one after another, and the speed was amazing.

The group of sharp stones smashed down, and the stratum cracked and collapsed in an instant, revealing the quicksand layer below, and the black sand and gravel swallowed the stratum and the sharp stones like a river.

Li Mo walked to the edge of the collapse and bent over to touch the rolling quicksand.

"I see. ”

He realized that this layer of quicksand was very similar to the entrance of the Dragon Yin Heavenly River, and the sand and gravel formed a vortex-like property between high-speed rolling, and had an extremely powerful suction, once it was rolled up, it would immediately pull into its depths.

And the depth of the quicksand layer is that even if Li Mo has ten zhang of eyesight, it is difficult to see the end.

After figuring out the structure of the quicksand layer, Li Mo got up, tiptoed slightly, and lightly crossed the collapse, landed in front of him, and continued to move forward.

Xiao Hei flapped his wings to keep up, and he was not in a hurry.

As we go deeper, things quickly get complicated.

Along the way, there are large areas of sharp rocks collapsing, which have no warning from the appearance, and cover a range of more than ten zhang.

If it weren't for Li Mo's discerning eyes that he could spy on the signs of detachment inside the sharp stone, it would have been difficult to completely dodge.

But you can imagine what a terrifying scene the treasure hunters experienced back then, seeing their companions being hit by a group of sharp rocks and falling into a layer of quicksand, that kind of scene will never be forgotten for the rest of their lives.

For Li Mo, no matter how frequent the collapse is, it will not cause danger, and the real complicating factor lies in the structure of the entire cave.

When you first enter the cave, you can still distinguish between the main road and the fork road. But now, there are more and more forks in the road, and it is getting wider and wider, and the path he has been taking has become a small road in comparison.

It has been half a day since I entered the cave, and this cave seems to have no end, and it is as complicated as an anthill.

"It's not a ...... way to go on like this"

Li Mo paused and pondered.

In the record of the falling grotto, there was once a strong man of the Heavenly Dome Realm who led 300 disciples to go deep into the cave, ambitious to find the treasures of the sect buried here, but after turning around in it for three months, not only did he not gain anything, but none of the 300 disciples survived.

This means that it is absolutely wrong to go aimlessly like this, and you must find the right path to the depths.

Since the quicksand layer swallows up a qiē substance, if there is a zài treasure here, it must be in the lowest layer of quicksand.

That's right, quicksand!

Li Mo suddenly had a flash of inspiration, and the memories of the time flashed through his mind.

He was well-eyed throughout the whole process, so the direction of the quicksand layer under his feet was also clear, and now when he recalls it, he has drawn a map of the flow of the quicksand layer in his mind.

However, the map of the quicksand layer of this road alone is not enough to determine the direction of the entire quicksand layer.

Therefore, Li Mo immediately turned around and walked towards another fork in the road.

He has a super memory that is difficult for ordinary people to reach, plus he has a good eye, so he doesn't have to worry about getting lost.

Moreover, he walked faster and faster, and the group of sharp stones fell faster and faster.

However, Li Mo's speed did not slow down, and after witnessing the falling of the sharp stones dozens of times, he had an extremely accurate grasp of the speed of its fall.

In this way, Li Mo traveled at high speed in the cave, passing by the sharp rocks again and again, and the stratum behind him was constantly collapsing.

In this way, it took three days, and Li Mo finally drew a map of the movement of the quicksand layer.

The layer of quicksand underneath the ground is like a spider's web, staggered in layers, and the flow direction is sometimes high and sometimes low, but it is enough for Li Mo to deduce the center of the quicksand layer.

This is impossible for others to do, and if you want to analyze the way out from the strata, let alone three months, even three years, you can't do it.

Knowing the end point, Li Mo immediately adjusted his direction.

As the road continues to move through the forks, the frequency of falling sharp stones becomes more and more dense, and there seems to be a hidden force preventing outsiders from approaching the end.

Moreover, the range of falling stones has also been greatly enhanced, and sometimes the area of dozens of zhang is a few tens of zhang when it falls, and the black quicksand like a river roars through the ground, swallowing a qiē substance in the process.

Not only the sharp stones in front of you fall, but sometimes the sharp stones suddenly fall from behind, and when the ground collapses, it spreads forward at a very fast speed, covering a hundred zhang long in an instant.

If someone else is replaced, even if it is a Heavenly Dome Realm Xuan Master, it will be difficult to escape the result of being trapped in the quicksand layer.

But Li Mo is different, when he encounters this situation, he jumps directly on Xiao Hei's back, and the defense layer is one, and he only needs to block the falling sharp stones, and he doesn't need to worry about the quicksand below.

It took another day, and on the fourth day of going deep into the cave, Li Mo finally reached the bottom of the cave.

This is a huge cave hall, hundreds of zhang long and wide, and in the cave hall is a quicksand pool.

The black sand swept in like a tide of Lang, conveying a restless aura and a strong suction.

But Li Mo was not afraid at all, but smiled slightly: "I finally found it." ”

Then he said to Xiao Hei, "You wait for me here." ”

After the words fell, he jumped into the pool without hesitation.

If anyone saw this scene, they would be shocked, and they told Li Mo to kill himself, this quicksand pool was able to kill all the powerhouses of the Heavenly Dome Realm.

But even though thousands of people are afraid, Li Mo is still full of confidence.

Since he was able to break through the Dragon Yin Heavenly River, how could he be afraid of this quicksand pool?

As soon as he entered the quicksand pool, he suddenly entered the vortex of the entrance to the Longyin Heavenly River, and the sand and gravel generated a force like crushing and squeezed towards him.

"Man of Steel!"

Li Mo secretly snorted, his whole body was as hard as King Kong, and coupled with the thirty percent defense added to the beast seal Storm Bear Armor, he steadily withstood this wave of impact.

Then there was a heavy suction force from below, and Li Mo followed the suction downward.

Each time you go down to the square, the impact force is doubled.

At this moment, Li Mo was not afraid, not worried, but immersed in a feeling of cultivation.

The blue water and red flame trick was transported, and the strands of blue water dragon qi and flame true qi were intertwined, floating on the surface of the body, and being tempered under the impact of the sand and gravel again and again.

With the help of upgrading to the first level, the martial arts of the two systems have also been upgraded to the triple realm and entered the stage of small success.

But Li Mo would never be satisfied with this mere achievement, he needed to cultivate tenfold and hundredfold to raise the two martial arts to the peak realm as soon as possible.

In the high-speed sinking, it reached a depth of 300 zhang in a short time.

At this time, a huge swirl appeared in the depths of the quicksand pool, trying to suck Li Mo in.

Li Mo was already ready to go, and at this time, his whole body was full of luck, and the whole person was shuttling down like a sharp arrow.

There was a heavy thrust from below, and the swirl sent out strands of suction, but none of them could stop Li Mo who was going all out.

The blue water dragon qi and the flame true qi were entangled around his body, and at this moment, Li Mo was like a double dragon protector, heading towards the depths of the quicksand pool.

After continuing to go deep for a full three hundred feet, Li Mo finally stepped on the ground.

Lingtong is now surrounded by black sand and gravel, and there is no way to find the treasures that may be hidden here, so he can only grope here step by step.

As we walked forward, we saw that there was gravel, and the quicksand at the bottom of the stratum was also in a flowing state, and there was nothing larger than gravel in my field of vision.

"Shouldn't it be like a hundred miles of black pool......

Li Mo muttered.

The Baili Black Pool was also formed by the explosion of the sect's formation, which almost destroyed the material in the Treasure Pavilion. In this way, all this sand and gravel may have been made from those destroyed spiritual treasures.

Although the spiritual treasures of Baili Heitan are broken, most of them are still stored in the form of fragments, but the destruction here has reached the size of gravel, which is enough to imagine how terrifying the explosion reached that year.

All the way through, nothing was found, except for sand and gravel.

This inevitably made Li Mo a little disappointed, could it be that this was really a veritable place of ruins.

It took almost five days, but there was no gain at all.

As he thought so, his eyes suddenly lit up, only because a wall appeared on the edge of the ten zhang in front of him.

He walked over quickly and saw that it was not a wall, but a stone storehouse!

The ten-zhang high stone vault is made of countless hexagonal stones, which shimmer with a faint blue luster.

"Kyanite!"

Li Mo recognized this thing at a glance and couldn't help but sigh.

Azurite is a rare type of seventh-grade ore, and although it is extremely hard, it is too independent to be cast into one. To refine this ten-zhang high kyanite library, it definitely took a lot of effort.

Look at the surface of the stone library there are still dense lines, fine carving, like a natural thing on the stone, that is the defensive array.

"This is the Nine Rings Defense Array!"

Li Mo's eyes flashed.

The Nine Ring Defensive Array, as the name suggests, is a nine-chain defensive array, which is very difficult to manufacture, but its defensive power has reached a point where it can be comparable to an eighth-rank magic array.

From the speckled marks and broken formations on the stone bank, it can be inferred that the Nine Rings Circle has been completely destroyed, but with the supreme hardness of the azurite, it can stand here.

Azurite ore coupled with the Nine Rings Array, it is destined that the things hidden in this stone vault must be good.

And the destruction of the magic circle also saved Li Mo's effort, and he pushed open the stone door with one hand and walked in.

This glance swept over, and he immediately sighed.

The stone library was a mess, and all kinds of broken spirit treasures and treasure boxes were scattered into piles.

It can be seen that the explosive power of the year still had the residual power to impact the inside of the stone vault after damaging the Nine Rings Defense Array, so that the treasures were destroyed.

But Li Mo didn't give up, after all, not all spirit treasures were too fragile to be vulnerable.

After searching through the ruins for a while, Li Mo really found a bunch of things, including three groups of seventh-rank formation pillars, four high-grade earth tools, and thirty-two kinds of materials.

Unfortunately, except for the materials, they are all things that are not used.

He is now cultivating the two systems of water and fire**, and he can use the formations of the water system and the fire system, but the three groups of formations are all from other systems.

As for the four high-grade ground tools, they are all axes and guns, and they are not useful.

At this point, the rubble pile was about to bottom out, and there was basically no hope.

But at this time, a long box was revealed underneath, and Li Mo was shocked when he touched it.
