The sparkling waves on the surface of the sea caused two behemoths to stir up high waves, causing some creatures to flee one after another, and the black mist bareen whales were swimming happily with jets of water from their backs.

At this time, Irandall looked up along the water column and noticed something unusual.

Having spent so much time in the ocean of inverted errors that it was easy to confuse what was really below, so when Elandall saw the gray world above him, he didn't come back to his senses.

But Rosen soon discovered that it was not a canopy, but a solid earth.

"Let's go now. ”

Fina said, and jumped straight to her feet.

Relying on the inertia of the black mist barbelen whale to float, Fina quickly left the whale's barrier and flew towards the "sky".

Then, amazingly, she didn't fall, but fell straight towards the gray-white sky.

Lawson immediately understood the mystery and flew into the sky with Randall.

Not long after breaking away from the barrier on the back of the Black Mist Barbel Whale, Lawson felt the direction of gravity change abruptly, from facing the sea to facing the sky.

The speed of the fall was getting faster and faster, but Fina was not panicked in the slightest.

Just when the three of them were about to land, they seemed to have hit a large soft net, and their landing speed suddenly decreased, and by the time they flipped their bodies and fell to the ground, they were no different from ordinary flat jumps.

"This is the security measure that the first explorers set up here, allowing the later explorers to enter this level faster. ”

Fina said, looking up at the space on the previous floor.

It was a sea of water that spread all over the sky, and the waves were magnificent, and a faint light shone through the sea, illuminating the entire space where they were.

It was only then that Elandall could see what the main body of the gray-white sky he had seen before was.

It's bones.

Looking around, this plain was all covered with mountains of white bones, these bones were of different shapes, some had long been weathered, and some of them seemed relatively new, and these white bones were obviously not the same creature, or even necessarily from the same place.

Irandall saw a huge whale skeleton, which appeared to be the remains of a black mist baleen whale, and inside this skeleton, there were the bones of some four-legged creatures, and she even saw the skull of a human.

The whole plain was silent, only the bones piled up.

"Is this the fourth floor......

Irandall felt that the scenery around him was a little creepy, like the world of the dead.

"Well, it should be right, this is the fourth layer of the Endless Abyss, the Desert of Death. ”

Fina nodded, and was a little jealous of the white bones around her.

Lawson didn't have anything, but had a feeling of returning home, although the plains were full of white bones, but unlike the skeletons in the ashes, there was no sign of magic attached to these bones, only a faint chaotic aura lingered, which should be caused by years of sedimentation.

The three of them were still observing their surroundings when they heard the sound of water splashing in the sky.

I saw that in the inverted sea, there were a large number of white bones, which fell like raindrops, and smashed on the other bones, raising a huge amount of dust.

The rain of bones continued for a long time, and eventually, the dust of the last bone settled, and the strange rain came to an end.

"Are there any creatures on this level?"

It occurred to Rosen that he had just done a cursory scan of the surroundings, but he didn't find any other creatures.

Bones abound, bone storms that fall from time to time, and desolate deserts don't look like they will have a complex ecosystem.

"As you have just seen, that storm of bones could have occurred in almost any corner of the plains, and most creatures would not survive in such a disaster. ”

Fina replied, looking at the hill of bones that had just been baptized by the storm and formed a new landscape.

"All those bones are from the ocean of inverted things?"

Irandall looked at the mess with trepidation.

According to the explorers, the remains of the dead creatures in the first three layers of the Endless Abyss were devoured layer by layer, and finally only bones remained, and they fell here, in other words, this is the cemetery that has been deposited for thousands of years. ”

Fina then explained that Fina had begun to walk through the desert, the ground was a fine white gravel, but now it seemed that these might have been weathered bones from decades or hundreds of years ago.

"But there are creatures in this level, and as I said, almost any corner can be hit by a bone storm, but there are also places that have not been invaded for many years, and such places have been turned into oases in the desert by explorers. ”

The three of them crossed a hill and saw an open wilderness, and among the hills of bones, there was a place that stood out from the rest.

It was a white fortress.

The mottled walls, the quaint shapes, look airtight, only a few towers drill out.

There is a lighthouse in the fortress that is shining on the surrounding land, and it is clearly inhabited.

"Most of the creatures grow in the oasis, and because of the unique environment here, the creatures are also very unique, and then, many years ago, the explorers built this observation post on one of the largest oases, which is also the deepest outpost in the endless abyss. ”

Looking at the fortress, Fina said slowly.

"There are many explorers who have stayed on this level for various reasons, and even left their children, and after many years of operation and construction, this place is no less than a small city. ”

The city in the middle of the endless abyss sounds unbelievable, but there is no doubt that the city is right in front of them at this moment.

"There are also some descendants of explorers, who have successfully broken through the load of the endless abyss after their own strength has improved, and have risen to the first level and seen the sun, most of these children of the abyss have also become famous explorers, but most of them still live here forever and will never see the sun in their lifetime. ”

A little embarrassed, Fina knew that she might have faced such a situation back then, but her parents still insisted on taking her to the ground, even if her life would be threatened.

"We'd better get out of here, no one knows when the Storm of Bones will come. ”

Fina retracted her thoughts and continued.

"The name of that fortress is Abyss, and it is also known as the Abyssal City. ”
