This creature ...... It's really made of bones.

This was Lynn's first thought after decomposing the rib centipede, and the carapace of its whole body was similar to that of a creature, although the carapace of the general arthropod also had some bone components in it, but there were still many differences.

But the rib centipede is different, it just has bones outside the body, and Lynn found that its internal structure is not like arthropods, but like a reptile, with organs such as lungs, muscles similar to vertebrates, and no hydraulic system.

This creature is not supposed to be an arthropod, but a creature that grows bones out of its body like a turtle, but this creature is also so strange that it is exactly like a rib, and the 'spine' of it is its body. The ribs are limbs, and there are six pairs of limbs in total, and the overall shape is quite similar to that of a centipede, but in fact it has only three pairs of limbs, and the other three pairs of limbs in the upper body are formed by knuckles, and its fingers have been specialized into the same structure as the limbs, but the residual structural form of the fingers can still be seen in the body.

It's a bit like a pterosaur, and the wing membrane is also stretched open by fingers.

This creature looks like a centipede, but it is a vertebrate, and it feels quite strange, and the most amazing thing is that there are small holes arranged in the three pairs of limbs of its upper body, which can be used to discharge a special substance.

Lin thought that it was collected from various corpse bones, these substances were very flammable, and when they came into contact with the air, they would burn a blue-green fire, so there was the same flame phenomenon as before, and then the ribbed centipede blew through small holes to push the flames to attack.

This one is really funny, it is estimated that the rib centipede turned out to be a scavenging creature. They live in piles of corpses for a long time and evolve. Its body also became skeleton-like. It is quite good for camouflage, not only does it look like a bone, but it also tastes like a bone, but there are still some bone-crushing creatures with a strong bite that may attack it, so they must also be defensive, and unlike those slow turtles, they are very agile in their movements, and the teeth in their mouths have become insect-like structures. It is suitable for shaving bones and removing meat.

They also have special vocal cords and can make a scream of "ah-" that Lynn finds even more interesting than the fact that they can set fires.

But what puzzled Lin was, why did they get mixed up with the scorpions? There should be no mutual benefit between the two creatures, but the ribbed centipede does lie on the scorpion......

Lin remembered the plague fungus, only after being infected by them, different types of creatures would mix, but this centipede was very normal, its brain was not affected in any way, and there should be no problem with its judgment ability. The same goes for scorpions, which Lynn has seen before.

It's certain that they've come to some kind of relationship. But how? Because scorpions are also scavengers? So they should be a little more competitive.

Leviathan placed the centipede on the ground, and Susumi immediately jumped down and grabbed it and began to eat, it grabbed the bone and tried to bite a few times, but it was too hard to bite.

Leviathan grabbed Susumi back onto his back and continued to fly deeper into the cavern.

There must be a secret to centipedes and scorpions......

There were quite a few bones on the cave floor, and Lynn felt like they had all been collected from the outside, but how did they drag such large bones so far?

Ahead, the cave became narrower, and although the Leviathan could still pass guò, Lin felt that it might get narrower and narrower, and it was not convenient to be too big.

However, after entering the depths, the previous feeling of 'cold' outside has subsided, and it seems that it has not affected this place.

The surroundings grew darker and darker, and the Leviathan lit up, and Lynn saw that the whole cave seemed to be covered with bones, and there were many ribbed centipedes lurking in it, and now Lynn could identify them very well.

This is......

Lin noticed that the cave in front of her suddenly became wider again, and reached the end, and the cave wall at the end was a completely flat wall, which seemed very suspicious at first glance.

Leviathan approached the cave wall and reached out to knock on it, which was made entirely of dirt and seemed to be soft.

"Gah!" Susumi suddenly screamed, and there was a 'boom' sound above the cave wall, and countless cracks appeared in the entire cave wall, and then it instantly cracked and disintegrated, turning into a pile of dirt and falling to the ground.

How fragile is this structure?

After the collapse of the smoke cleared, the Leviathan's light shone on the cavern behind the cave wall, and the sight before me was...... A swath of flying creatures!

Countless blackened flying creatures creaked towards the Leviathan, what appeared to be a small pterosaur, and instead of attacking, they all flew away towards the exit of the cave.

It wasn't until they flew away that Lynn really got to see the structure of the cave.

This is...... Water?

Behind the cave wall is a huge underground lake nearly 100 meters wide, and the water of the lake occasionally glows with wonderful brilliance, probably because of the presence of luminescent microorganisms.

Leviathan reached out and created something like a transparent hood and put it on Susumi's face, which Lynn called the 'Filterer', with a set of small organs at the bottom that filtered the air in the water for Susumi to breathe.

"Gah? What is it? Susumi fiddled with the hood on her head curiously.

"Don't get it, you can get air in the water."

As Lynn spoke, the filterer inhaled the air and swelled instantly, and the Leviathan entered the water with it.

"Water! Water! Susumi shouted excitedly from the hood, while Lin observed her surroundings, and through the light radiating from Guò Leviathan, Lin saw that the surface of the lake was covered in dense crystals, occasionally protruding from a large crystal column.

There are still many scorpions active on the crystals at the bottom of the lake, and they are completely amphibious creatures.

There were also a lot of fish, some small fish swam around the Leviathan, and Susumi kept trying to catch them on the Leviathan's back, not knowing if the fish had swam in from the outside or had been brought in by other creatures.

If you swim in...... There may be some passages leading to the outside.

Beneath the lake, Leviathan had seen a number of caves, they were of various sizes, and they were full of crystals, some fish were hiding in them, and most of these fish had no crystals on their bodies, and Lynn thought that there must be some cave that could lead to the river and other places outside......

…… It's ......

Lin suddenly noticed something ahead, Leviathan immediately turned off the light, and the surroundings fell into darkness for a moment, and at this time, in the lake, there were a lot of fluorescents, and they floated in the water, and now Lin could see that they were tiny creatures.

About ten meters in front of the Leviathan, there was a place where fluorescent clusters, and it was not a tiny creature, but a ...... that was nearly two meters long Arthropods?

The body of this arthropod is fluorescent, and its body is somewhat like a scorpion, its front limbs are relatively slender, and the bottom limb is very thick, which looks like a ...... Leg? Does it move on its legs?

The creature was lying on the crystals of the bottom of the lake, with eight eyes on its head, all closed, as if it were sleeping at the bottom of the lake.

Does this arthropod have eyelid-like structures that allow the eyes to close? This is the first time I've seen it, or maybe it's not an arthropod, but a vertebrate creature with bones growing outwards like a ribbed centipede?

However, the creature has scorpion's pincers and hooked tail, and it does look like a scorpion-like creature......

As the Leviathan slowly approached, the creature suddenly opened its eyes, and it was startled the moment it saw the Leviathan's massive body with its own fluorescence! It swayed in a panic and fled from the Leviathan.

This creature swims mainly by swinging its arthropods, and looks very clumsy, and the Leviathan can easily catch up with it, this may be a land creature that doesn't know how to run into the water...... Go to bed?

When the creature realized that the Leviathan was about to catch up with it, it immediately turned around and burrowed into a cave at the bottom of a lake......

The cave was too narrow for the Leviathan to enter, and Lynn watched as the fluorescent glow slowly faded away through the cave, which seemed to be a long passage......

"Got in, escaped!" Susumi looked inside the entrance of the cave, it seemed to want to catch up, its body was completely in, Lin suddenly thought of a way, and then said to Susumi: "Go in, track the target, don't disturb the target,"

As he spoke, Leviathan glued two eyeballs to Susumi's hood, which looked like a hat with eyes.

Speaking of which, the 'hat' refers to something that is worn on the head, right? That sounds like a strange word......

"Quack...... Susumi was puzzled for a moment, and then swung his body and swam into the cave, which contained fluorescent creatures that allowed Susumi to see his surroundings clearly......

The jade dragon's swimming skills were not bad, at least faster than that creature, and the creature's fluorescent body soon appeared in front of Lin's eyes, and Susumi kept her distance and followed it, swimming slowly without being detected.

The passage is very long, and there are many creatures here, such as fish and various arthropods, shellfish, etc., and the underground structure is quite complicated.

After swimming for tens of meters, Susumi followed the creature out of the cave and into another lake.

The lake was small, and the creature swam to the shore and climbed up, and Susumi also stuck his head out of the water to observe......

The moment Susumi surfaced, the first thing Lynn saw was a large pile of ...... The bones of living beings.

The creature walked on top of the pile of bones, and it moved with two pairs of knuckles on its lower body, while its upper body moved upright, but what made Lynn see the strange was the environment and the creatures.

It's a biological population, but it's a little different...... (To be continued......)
