Li Mubai and the four of them hurried quickly towards the place where the abyss was, and a few hours later, they had already rushed all the way to the fourth layer of the abyss.

At this time, the wounds on their bodies have formed blood scabs and are recovering.

When they came here, they saw the huge stone pillar that stood on the fourth floor of this abyss!

His dragon source was found on this stone pillar, and the second time he saw it, this stone pillar was still so majestic and magnificent!

All the way down the stone pillar to the bottom of the abyss, this stone pillar actually went deep into the earth I don't know how long.

Moving on, they didn't find a single abyssal beast at the bottom of this abyss full of crises, as if they had been completely swept away!

This Frog King and Tiger Shark King are really powerful, they can even sweep away the four layers of the abyss, it seems that they have really put a lot of effort into it!

The area of the fourth layer of this abyss is extremely vast, and after Li Mubai and the four of them advanced for dozens of miles, they found that the Sea Clan Evolutionaries of the Frog Jiao Palace and the Tiger Shark Gate were transporting huge stones from the huge rock walls on both sides!

Most of these evolutionaries are second-order, with the majority of them being crustacean sea tribes.

And this place is very different from the rest of the abyss, there is a light source here!

There are many ores that emit faint fluorescence among the rocks at the bottom, and although the light is still dim, the evolved sea tribes can see here without obstacles.

"What's on those rock walls, caves?"

As soon as the old turtle said, Li Mubai and the others all looked at it, and on the stone walls in the distance, there were huge and dark caves, what is this!

Moreover, the sea clans of the two major forces are all in and out of those caves, carrying out quaint boulders, and they seem to be cleaning the passages!

Li Mubai opened his eyes half-open, his eyesight expanded dramatically, it was like an all-round detector, and all the sea clans within five kilometers of the surrounding area fell into his eyes.

After observing around, Li Mubai said: "The strongest here are a few fourth-order evolutionaries, there is no threat to us for the time being, those huge caves were not dug by them, and those quaint aura on them should have existed since ancient times." ”

"This should be the ancient ruins of the shark five words!"

"Let's go in and have a look!"

After saying that, the four of them immediately gathered the breath on their bodies and quickly touched into the nearest cave, and under the control of their energy, the surrounding sea water did not emit huge fluctuations.

With the improvement of the level of evolution, Li Mubai found that the old turtle's turtle breath technique was becoming more and more effective, and it was able to completely cover its own breath.

This can play an important role in both lurking and escaping!

And the knife and the skin shrimp have also recently learned the turtle breath technique, which can bind the energy in their bodies.

Touching into that cave, Li Mubai immediately stunned a second-order sea clan without making a sound, and then everyone walked all the way along this cave.

The caves were so large that they didn't feel crowded even when they entered them, and they were carved into the rock faces.

The pattern is a humanoid creature with a human upper body and a fish's tail on the lower body, and these are mermaids, or mermaids?

The inscriptions depict the war and hunting of the mermaids, and the object of their hunt is a huge underwater beast.

"Did these things happen in ancient times? Do mermaids really exist?"

"That's right, now the world has become so magical, all kinds of demons and monsters have appeared, and it's normal to have mermaids!"

After turning around, Li Mubai and the others found that they had been moving down, and Li Mubai had stunned many sea clans along the way.

Finally, ten minutes later, Li Mubai and the others walked down for thousands of meters in the passage, and finally came to the end of the passage, but this place collapsed!

Ahead were boulders blocking the way.

In desperation, several people could only carefully move away from those boulders one by one and continue to move forward.

Suddenly, after Li Mubai opened a boulder of dozens of meters, a bright ray of light in front of him radiated from the crack in the stone, which was extremely dazzling in this dim environment!

The appearance of this ray of light shocked the four of them!

Quickly moved away the remaining boulders, and a huge light curtain appeared in front of several people's eyes, and behind that light curtain, a huge and magnificent hall appeared!

The hall is resplendent with beautiful patterns carved on the walls, and in the center of the hall there are nine huge pillars carved with mysterious runes leading to the dome of the palace, supporting the huge palace.

In the palace, there are rockeries, colorful coral jungles, and even nine hundreds of meters of huge snow-white back shells dotted in the palace.

In those back shells, the huge snow-white pearls exude a white brilliance, each of which is larger than a person, illuminating this hall very brightly!

"Such a huge shell, such a big pearl, how many steps do those sea shells have to evolve to?" Including Li Mubai, the four of them were all stunned by the scene in front of them!

Li Mubai and the others were in the passage at the bottom of the hall at this time, and from a distance, this should be one of the side doors of the hall.

Because at the main entrance, there are two 100-meter-high merman statues guarding both sides with steel forks.

The stone statues of the mermaids are carved vividly, and even their serious expressions can be seen clearly!

"These stone caves finally lead to this palace, it seems that the Frog Jiao Palace and the Tiger Shark Gate have not yet discovered here, we may have encountered treasures!"

At this time, the old turtle's eyes lit up, staring at the golden palace road above.

"These ancient palaces are guarded by formations, we can't let our guard down, we must be careful. ”

Li Mubai raised his fin and touched the light curtain in front of him, and his fin penetrated easily as if it had touched the surface of the water, almost no resistance, and no attack occurred.

And the palace was also dry, and all the sea water was isolated!

"Is this curtain of light just blocking the sea?"

Li Mubai's entire body passed through the light curtain and officially stepped into the palace, such a glorious palace, only when you step into it can you feel its majesty!

Seeing that Li Mubai stepped in, the three of them also quickly passed through the light curtain and entered the palace, and what was even more peculiar was that the water traces on their bodies through the light curtain dried directly, as if they were instantly evaporated by some force.

On both sides of the palace were many fruit trees planted and bearing many fruits, but they were dried up and had no energy.

And it turns to ashes at the touch, and it's so quiet that there's no sign of life.

After some observation from the periphery, several people made their way along the central avenue to the depths of the palace.
