Lu Menglin suppressed the qi and blood all over his body, his pores were tightly closed, and suddenly a layer of dense goosebumps appeared all over his body, which was a reaction that spread all over his body.

Immediately afterwards, Lu Menglin's left arm turned blue and black again, the green tendons burst out, the skin membrane tightened, and turned into a half-cut ghost arm, blocking his chest.

Even if he can't resist that troll, he will never be restrained! Lu Menglin had already burst out with all his physical strength in an instant, his right hand held his waist, and with a slight touch, he pinched the Tai Sui Myelin Mother in his hand, continuously replenishing his physical strength.

The giant monster in front of him was fierce, but it didn't pounce.

Lu Menglin didn't dare to be careless, and still maintained a state of full combat power explosion, his eyes staring at the giant monster.

Finally, he realized that something was wrong.

The troll didn't seem to be a living thing, and although it was lifelike, it didn't move, and it hadn't changed at all from before to now.

Lu Menglin came to his senses, and when Dingqing saw it, he couldn't help but almost scold his mother.

"Who is so lacking in morality! Putting such a large piece of crystal ore fossil here will make people almost scared to pee!" Lu Menglin was a little annoyed and angry, and said to himself.

The crystal ore fossil in front of him is not so much a fossil as a fossil mountain, because this huge crystal ore with a height of more than 30 meters can really be described as a small mountain.

If you hadn't seen it with your own eyes, it would have been hard to imagine how such an incredible thing could have happened.

Sealed in the crystal mine is a megalodon, the overlord of the ancient seas, which only existed tens of thousands of years ago, when humans were not really born.

Looking at the behemoth in front of him, Lu Menglin was not only amazed, but also fell into a long period of contemplation.

When he saw the fossilized head of the dire cat before, Lu Menglin thought it was some kind of accident, so that the unlucky dire cat was sealed in the crystal ore and accidentally preserved the form.

This amberstone-like state is not uncommon in the evolution of the earth over millions of years.

But the crystal mine in front of him made Lu Menglin overturn his previous thoughts.

This megalodon can't be so unlucky to be sealed in such a large piece of crystal ore!

Moreover, the composition of this crystal ore is extremely rare, and it can preserve the breath of living beings to the greatest extent, and even the protein cell components, Lu Menglin does not believe that this big guy is sealed in the crystal ore, which is also some kind of coincidence.

It seems that there is a big secret in this place! Lu Menglin couldn't help but exclaim in his heart.

He took his eyes off the megalodon and began to survey his surroundings.

The surroundings were empty, the space was huge, and it constantly emitted a soft light source, sparkling and shining.

Lu Menglin was shocked when he saw this.

Because all of these surroundings are composed of crystal ore, if the upper layer is the composition of the rock containing crystal ore, then this layer is constructed with this crystal ore as the main body.

When the amount of this crystal ore reached a certain level, Lu Menglin discovered that they emitted another characteristic of light, that is, they would emit a pale yellow light, and these rays would coalesce together to form a light film that could block seawater.

Lu Menglin has never heard of this kind of material, even if he is a reborn person and has experienced the era of information explosion on the mobile Internet, he still has never heard of this kind of thing.

And Lu Menglin was also surprised to find that in addition to the huge megalodon shark around, there were also some potholes of different depths on the crystal rock wall.

At first, Lu Menglin didn't know what these pits represented, and he was worried that it would be some kind of creature's lair, but

When he got closer and looked closer, it dawned on him.

The holes in the rock walls of these crystals are clearly something that has been sealed off in the past, but they have just been dug up.

At first glance, those holes are not naturally formed, but have been dug by someone with sharp weapons, and there are traces of excavation.

Lu Menglin closed his eyes, thinking of this island, especially the various experiences after entering the mining area, and finally made a bold guess.

This crystal ore is one of the materials used by Hainuo Lab to make secret medicines, so the upper layers are for those warriors to desperately mine and excavate, and use them in exchange for resources.

And the more you go to the lower mining area, the difficulty of entering increases exponentially, and only powerful people can enter, and the number of these powerful people is a minority after all, so they can only dig up those smaller crystal ore fossils.

The ore that has sealed the living creatures in the crystal ore is obviously much more valuable than the ordinary crystal ore.

The Hainuo laboratory is willing to pay a lot of money for this crystalline fossil. And the big guy in front of him, it is estimated that those strong people can't get out, so they dug up all those who can dig it out, so they have to leave this big guy here.

The more Lu Menglin thought about it, the more he felt that this speculation was very reasonable, but he didn't know how big this mining area was and how many crystal ore fossils existed.

"Something is wrong! Although the crystal ore fossils close to the light film have been dug up, there must still be some in them, but why is there so little crystal ore fossil production in the mining area?" Lu Menglin couldn't help but look around after thinking of this question.

There was a faint sense of crisis in his heart, and he always felt that this place was weird, and it didn't seem to be so simple.

At this moment, Lu Menglin made a new discovery.

He saw that there was something black on the tail of the megalodon, not a part of the megalodon.

Lu Menglin's body moved, and he crossed thirty meters in two steps and came to the black thing.

After taking a closer look, Lu Menglin suddenly gasped.

Because that swarthy thing is a boundary monument, and there are only three big characters on it, "The Fifth Prison".

On the back of the boundary monument, there was a black skeleton, the skin and flesh had been shriveled and withered, and only the skeleton was still not scattered.

"Fifth Prison, isn't this the fourth layer of the mining area?" Lu Menglin muttered to himself.

"Could it be that the sea area that I dived down just now is also a first-layer mining area?" Lu Menglin only came to such a conclusion.

"This name is quite imposing, much more domineering than the word mining area. Lu Menglin smiled bitterly.

He leaned down and took a closer look at the skeleton holding the boundary marker.

This man's bones are very thick, and although he is dead to the point of being reduced to only a skeleton, he still has the momentum of a tiger that will not fall.

Just the action before he died, holding the boundary monument, seemed to want to jump up, and there was the rhyme of a tiger jumping into the stream.

And this person's boxing skills are estimated to be much more clever than Ba Shengrong, and the posture of the last leap is full of a sense of power, almost flawless, and he can't find any weaknesses.

The more Lu Menglin looked, the more he felt a little frightened, this dead man could die here, and nine times out of ten he was also a great master who had trained Gang Jin, just being able to hold his breath and sneak in, it was no longer just an ordinary Gang Jin martial artist.

But he died here quietly! What is the danger here? Even such a great master is dead.

If this danger arises, will I be able to resist it?

As soon as Lu Menglin thought of this, he almost immediately wanted to turn around and leave.

However, as long as you think that there are as many as nine floors in this mining area, this layer is only the fifth prison

That's it, Lu Menglin immediately calmed down again.

A person like Tu Xiaoxiao is estimated to have been here and returned alive, maybe with his ability, he can continue to go down to the back floors.

Thinking of this, Lu Menglin was not so panicked, since he had come, he had to see this place clearly.

Just when Lu Menglin hesitated, the ground under his feet suddenly made a strange sound.

It's like the gurgling sound of a bubble coming out of the bottom of the water.

Immediately after, Lu Menglin saw a drop of water.

That's right, a drop of water came out of the black boundary monument and floated into the air.

People go to high places, and water flows to low places, which should be common sense, but it was broken by this scene in front of him.

A drop of water floated into the air, and Lu Menglin's eyes suddenly focused on this drop of water.

After a while, only the sound of rushing water was heard, and then more and more droplets of water were seen emerging from the boundary monument.

Lu Menglin swept the corner of his eyes, turned around in shock, and found a small fish swimming in the air.

It is a small fish with a glittering body that looks beautiful, and it has the feeling of a glowing firefly flying in the night sky.

Immediately afterwards, more and more small fish appeared in all directions, and they swam happily in the air in groups, very smart.

At this moment, Lu Menglin had the illusion that he was actually in the water.

He couldn't help but take a deep breath, clearly feeling the presence of air, still able to breathe, what was going on in front of him?

Is it an illusion? Or is it something else?

Lu Menglin was amazed, stretched out his fingertips, and gently flicked towards a small fish swimming past him.

The fingertips intertwined with the body of the small fish, which did not affect the swimming of the small fish, and Lu Menglin did not feel that he touched the small fish.

Between the two, it seems to exist in parallel space at the same time, Lu Menglin's eyes can see, but his body can't touch it.

There are more and more small fish in the air, forming a huge school of fish, giving people a feeling of covering the sky and the sun.

At this time, the school of fish suddenly dispersed, and a large hole was exposed in the middle of the formation.

It turned out that a tiger shark broke up the fish, this tiger shark is not small, nearly seven or eight meters in length, in mid-air like a battleship rampage, so not majestic.

Immediately after, more and more sea creatures appeared in this strange space.

Lu Menglin knows dozens of them alone.

The giant turtle slowly swam overhead, the Australian lobster held a large pair of pincers, and the body flicked forward in mid-air, and the two huge manta rays fanned their bodies, darkening the light above their heads, until they left, and then re-revealed their light.

Several dolphins swam around Lu Menglin playfully, as if they had spirituality, they looked cheerful and lively.

There are also many marine species that Lu Menglin doesn't know, some are huge, and some are in groups, swimming in the air one after another.

And these creatures all have a common characteristic, that is, they are stained with a thin layer of fluorescent color, sometimes dim, sometimes flickering.

Lu Menglin knew that this layer of light was probably the key to making them reappear here, and he didn't know what kind of condition these sea creatures existed in front of him.

However, he only knew that this scene was very beautiful, simply beautiful.

It's a magnificent scenery of nature, a unique beauty that marine species are born with, and it's fascinating and intoxicating.
