It was too late, but it was soon! Lu Menglin suppressed the energy and blood all over his body, his pores were tightly closed, and suddenly a layer of dense goose bumps appeared all over his body. This was a reaction to the strong energy spreading throughout his body.

Immediately afterwards, Lu Menglin's left arm turned blue and black again, the veins popped out, and the skin tightened, turning into half a ghost arm, blocking his chest.

Even if he couldn't resist the giant monster, he would never sit back and wait for death! Lu Menglin had exploded all his physical energy in an instant. He put his right hand on his waist and pinched the Tai Sui Marrow Mother in his hand with a gentle touch, continuously replenishing his physical strength.

Although the giant monster directly in front showed its fierce look, it did not pounce on it.

Lu Menglin did not dare to be careless, and still maintained his full combat power, staring closely at the giant monster.

Finally, he discovered something was wrong.

The giant monster didn't seem to be a living thing. Although it was lifelike, it didn't move. It didn't change at all from before to now.

Lu Menglin regained consciousness, and when Dingqing saw it, he almost cursed her.

"Who is so wicked! Putting such a large crystal mineral fossil here will scare people to the point of peeing!" Lu Menglin became a little angry and said to himself.

The crystal mineral fossil in front of us is not so much a fossil as a fossil mountain, because this huge crystal mineral with a height of more than thirty meters can really be described as a hill.

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

What was sealed away in the crystal mine was a megalodon. This kind of ancient overlord of the ocean only existed tens of thousands of years ago, a barbaric era before human beings were truly born.

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

When he saw the skull fossil of the dire cat before, Lu Menglin thought it was some kind of accident that caused the unlucky dire cat to be sealed into the crystal ore, accidentally preserving its form.

This amber stone-like state is not uncommon during the millions of years of evolution of the earth.

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

This megalodon couldn't possibly be so unlucky to be trapped in such a large piece of crystal ore!

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

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

He finally moved his eyes away from the megalodon and began to look at the surrounding environment.

The surroundings were empty, the space was huge, and soft light sources were constantly emitting, shining brightly.

When Lu Menglin saw this, he was immediately shocked.

Because the surrounding areas are all composed of crystal ore, if the previous layer contains crystal ore in the rock, then this layer is mainly constructed with this crystal ore.

When the quantity of this kind of crystal ore reached a certain level, Lu Menglin discovered another characteristic of them, which was that they emitted a light yellow light, and these lights gathered together to form a light film that could block seawater.

Lu Menglin had never heard of this kind of material. Even though he was a reborn person and had experienced the era of information explosion on the mobile Internet, he still had not heard of this kind of thing.

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

At first, Lu Menglin didn't know what these potholes represented, and was worried that they might be the nests of some kind of creatures. However,

When he got closer and took a closer look, he suddenly realized.

The holes in the rock walls of these crystal mines were clearly where something had been sealed off, but they had just been dug away.

At first glance, those potholes were not formed naturally, but were dug out by someone with sharp tools, and there were traces of excavation.

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

This kind of crystal ore is one of the materials used by Hainuo Laboratory to make secret medicine, so the warriors on the upper floors are working hard to mine and use it in exchange for resources.

As you get to the lower mining area, the difficulty of entering increases exponentially. Only powerful people can enter, and the number of these powerful people is only a small number after all, so they can only dig out the smaller crystal mineral fossils.

The ore in which living things are sealed in the crystal mine is obviously much more valuable than the ordinary crystal mine.

Hainuo Laboratory is willing to spend a lot of money for this kind of crystal mineral fossil. As for the big guy in front of us, it is estimated that the strong ones can't get it out, so they dug out all the ones that could be dug out, so they had to dig out this big guy.

Stay 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 the mining area was and how many crystal mineral fossils existed.

"Something's wrong! Although the crystal mineral fossils near the light film have been dug away, there must still be some inside. But why is the output of crystal mineral fossils in the mining area so small?" After Lu Menglin thought of this problem, he couldn't help but look around.

There was an indescribable sense of crisis in his heart, and he always felt that this place was weird, and it didn't seem that simple.

At this moment, Lu Menglin made a new discovery.

He saw what seemed to be a dark thing at the tail of the Megalodon, which did not look like a part of the Megalodon's body.

Lu Menglin moved and crossed thirty meters in two steps, arriving in front of the black thing.

After taking a closer look, Lu Menglin suddenly took a breath of cold air.

Because that dark thing is a boundary monument, with only three big characters flying like dragons and phoenixes on it, "Fifth Prison".

On the back of the boundary monument, there is a black skeleton. The skin and flesh have shriveled and fallen apart, but only the skeleton is still intact.

"The fifth prison? Isn't this the fourth level mining area?" Lu Menglin said to himself.

"Could it be that the sea area where we dived just now can be considered a first-level mining area?" Lu Menglin could only come to this conclusion.

"This name is quite majestic, much more domineering than the word "mining area." Lu Menglin said with a bitter smile.

He leaned down and looked carefully at the corpse holding the boundary monument.

This man's bones were very strong. Even though he was dead and only a skeleton was left, he still had the aura of a tiger that would never fall down.

Just the movement he made before he died, holding the boundary monument as if he wanted to jump on it, had the meaning of a tiger leaping into a stream.

Moreover, this man's boxing skills are probably much better than Ba ​​Shengrong's. The final leap was full of power and almost flawless, with no weaknesses to be found.

The more Lu Menglin looked at it, the more he felt frightened. For this dead man to die here was most likely a master who had mastered Gang Jin. Just by being able to hold his breath and sneak in, he was no longer just an ordinary Gang Jin warrior.

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

If this danger arises, can I withstand it?

When Lu Menglin thought about this, he almost immediately wanted to turn around and leave.

However, once you think about the fact that this mining area actually has nine floors, this floor is only the fifth prison.

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

Someone like Tu Gongchun has probably been here before and returned alive. Maybe with his ability, he can continue to go down to the later floors.

Thinking of this, Lu Menglin was not so panicked. Since he had already come here, he had to see this place clearly before talking about it.

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

It's like the sound of bubbles rising from the bottom of the water.

Immediately afterwards, Lu Menglin saw a drop of water.

That's right, it was a drop of water that emerged from the black boundary monument and floated into the air.

When people go to higher places, water flows to lower places. This should be common sense, but it was broken by the scene in front of us.

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

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

Lu Menglin glanced out of the corner of his eye and turned around in shock, only to find a small fish swimming in mid-air.

This is a small fish whose whole body is shining with light. It looks very beautiful, and it feels like a firefly flying in the night sky.

Immediately afterwards, more and more small fish appeared in all directions. They were in groups and swimming happily in the air, very agile.

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

He couldn't help but take a deep breath. He could clearly feel the presence of air and was still able to breathe. What was going on with all this?

Is it an illusion? Or something else?

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

The fingertips crossed the small fish's body, but it did not affect the swimming of the small fish, and Lu Menglin did not feel that the small fish was touched.

The two seemed to exist in parallel spaces at the same time. Lu Menglin could see them with his eyes, but couldn't touch them with his body.

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

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

It turned out that a tiger shark dispersed the fish school. This tiger shark was quite big, nearly seven or eight meters in length. It was like a battleship in mid-air, so majestic.

Immediately afterwards, more and more marine creatures appeared in this strange space.

Lu Menglin knew dozens of them alone.

A huge sea turtle slowly swam over the head, an Australian lobster held up its big claws and bounced forward in mid-air. Two huge manta rays flapped their bodies, darkening the light above their heads.

Dark, until they left, the light was revealed again.

Several dolphins were swimming around Lu Menglin playfully. They seemed to be spiritual, cheerful and lively.

There were also many marine species that Lu Menglin didn't know. Some were huge, and some were swimming in groups in the air.

These creatures all have a common characteristic, which is that they are covered with a thin layer of fluorescent color, which is sometimes dim and sometimes flashes.

Lu Menglin knew that this layer of glimmering light was probably the key to making them reappear here, and he didn't know what condition these marine creatures were in before his eyes.

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