Xu Ding was stunned by the underwater world and looked around curiously.

As far as the eye can see, I see schools of fish swimming around, some of which are common local fish species that I know, some of which are just familiar and do not know the name, and some of which I have never even seen.

These fish have an obvious characteristic, that is, they are large, even ordinary crucian carp, there are more than half a meter long, and there are not a few fish that are more than one meter long.

Seeing such an underwater ecology, Xu Ding secretly sighed that it was no wonder that the lizard dragon could live here, and there was no mountain disaster.

There's enough food here to eat it.

Dive into the depths, the dragon swings its tail and swims nimbly through the water.

Everywhere it passed, all the fish fled like an emperor.

However, Xu Ding also found that in the underwater world, there were also a few strange fish that were not weaker than the lizard dragon, and they were not frightened by the lizard dragon, although they were also swimming in the distance, they did not escape.

"Sooner or later, I'll eat you all."

Xu Ding suddenly sensed a malicious thought from the lizard dragon.

After being stunned for a moment, Xu Ding smiled dumbly, this product is really domineering.

However, such an underwater world, Xu Ding is also very excited when he sees it, it is hidden, huge, and there are rich fish species inside, and it will inevitably be able to be turned into a backyard pond in the future, with many functions.

As he pondered, suddenly the figure of the dragon swung and swam towards a dark water.

Just approaching the dark waters, Xu Ding changed color in vain.

He felt a looming coercion, a terrifying aura that was inadvertently emitted by a powerful being, and in the face of such an aura, any animal that he sensed would flee far away.

Xu Ding was also a little hesitant, but his mind communicated with the lizard dragon, but the lizard dragon passed on a thought that it was okay, and it seemed that he was very accustomed to the coercion here.

Xu Ding didn't interfere anymore.

He was also curious.

In such an era of the end of the law, how could there still be such a powerful existence between heaven and earth? Even if it hid, it couldn't avoid the general trend, and eventually died in various accidents.

In addition, the coercion he perceived, although powerful, floated, unlike that emanating from a living being. It is possible that the remains of the powerful zài were left behind.

After all, a truly terrifying person, even a corpse, is enough to deter countless low-level species, and people dare not desecrate their bodies.

When he was young, the dragon burrowed into the dark waters, and when he entered here, Xu Ding realized that the dark waters were actually a mountain in the water, and the mountain walls were pitch black, so it seemed that the waters in this area were bleak.

However, the dragon swung its tail and slammed into a mountain wall with its skillful body. Drilled into a hole in the water.

After seven turns and eight turns, his eyes suddenly opened up, and a faint blue light appeared in front of Xu Ding.

Without waiting for Xu Ding to ask, the dragon rushed up quickly, and with a poof, the dragon rushed out of the water and entered an underground water hole.

Xu Ding rode on the back of the dragon and looked around curiously.

This water cave is not big, only five or six meters in radius, and on the edge of the water cave, it is a karst cave.

There are many caves, the size of several football fields, the caves are more than ten meters high, and the stalactites that emit blue light are hanging down.

Illuminated by the blue light, the cave was bright.

Suddenly, Xu Ding's eyes froze.

He saw something magical.

It is a signboard that hangs between two stalactites on the top of the cave.

This signboard is shining with golden light, and there are four immortal characters on it.

Xu Ding studied Xianwen carefully and recognized the meaning of these four words at a glance.

Bilongtan House.

Sure enough, there is a master in this underwater world, and the master is also a terrifying predecessor of his fellow practitioners.

Xu Ding jumped from the lizard dragon to the shore and said to the lizard dragon: "You brought me here, do you want me to visit the seniors here?" ”

The dragon nodded, and then climbed ashore as well, and entered the cave through the road under the plaque of the Bilongtan Mansion.

Xu Ding groaned for a moment and followed.

Along the way, looking at it all the way, Xu Ding's expression became more and more strange.

The arrangement in this cave is very peculiar, rockery coral, jewelry, fine dust, it looks very luxurious.

After turning a few corners, a building suddenly appeared in front of Xu Ding's eyes.

This is a splendid hall, left and right are pavilions, eaves and paintings.

But what is surprising is that there is such a magical and huge building, but it is quiet and uninhabited.

Xu Ding walked in quickly, and when he arrived in front of the main hall, his eyes were raised, and his expression was instantly dull.

Above the main hall, there are also three Xianwen door plaques, which are written, Bilong Palace.

Ryugu! Ryugu! Under this waterhole, there is actually a dragon palace!

The shock in Xu Ding's heart was indescribable.

In fact, I should have thought of it a long time ago, such an underwater world, such an underwater cave, and the immortal inscriptions used on the door plaque all pointed to the Dragon Palace.

It's just that Xu Ding didn't see it with his own eyes, so he didn't dare to be completely sure.

Shocked for a long time, Xu Ding calmed down and looked at the hall with a solemn gaze.

The faint coercion he felt emanated from this hall. If nothing else, it must be the Blue Dragon King who exudes this kind of coercion.

Dragons? I didn't expect to have an insightful day.

Xu Ding was afraid, but more curious and excited.

Being able to see a real dragon with their own eyes is something that many mortals dream of.

But to be honest, there is still a gap between what you want to see and what you really see, this is Ye Gong is a good dragon, he is not afraid of dead things, but when he sees a living thing, how can mortals not be afraid.

Xu Ding restrained his feelings and walked into the main hall with his feet raised.

Entering here, Xu Ding's eyes suddenly froze.

He saw a mess all over the ground, a place full of bones, and there was a fight here?

was surprised, and suddenly Xu Ding's eyes widened.

In the depths of the main hall, a huge skeleton was wrapped around the golden pillar, its head raised high, as if it was letting out an unyielding roar, as if asking something.

But it's dead, and all that's left is a body full of bones, like steel, mighty and unyielding.

This skeleton is exactly ...... Joist!

Xu Ding looked at the dragon bone blankly, he had already guessed that the dragon king of the underwater cave might not be alive, but when he saw it with his own eyes, he was still silent. The heart is even more mixed, and there are no words to say.

Just as he was losing his mind, Xu Ding suddenly heard Angang's cry, which contained sadness and sadness, and Xu Ding came back to his senses in shock.

After a closer look, Xu Ding found that it was the dragon calling, lying in front of a miserable white corpse that resembled it, rubbing gently, and tears the size of bird's eggs in its blue eyes continued to flow.

Seeing this, Xu Ding suddenly understood something. Silently walked over, stretched out his hand and touched the dragon's head, and his eyes were much gentler.

After a while, the dragon stopped crying, and Xu Ding also took the opportunity to look around.

In the main hall, the keel is coiled around a golden pillar, and around the keel, there are bones of other species all over the ground.

Xu Ding carefully distinguished, and found turtles, lobsters, crabs, and big fish.

But these are all turned into white bones, and the turtle is only left with the shell, the lobster and crab are only left with large tongs, and the big fish is only left with fish bones.

Seeing the desolation, Xu Ding couldn't help but feel sad in his heart.

The dragon king is dead, the turtle prime minister is dead, and the shrimp soldiers and crab generals are also dead.

What kind of terrible catastrophe is it, it is so ferocious, and it is exterminated.

Ask for collections, ask for recommendations, ask for rewards.
