Fish belly city is the place where the merman clan lives, and when he heard the name, he knew that there would be no exit to the outside world, Xu Yan skipped the fish belly city and directly asked Xiao Xi to take him to see the demon king elder.

If even the Demon King Elder doesn't know how to get out, I'm afraid he really won't be able to get out, and if he wants to leave, he can only wait until after October.

Through the gauze-like passage, the two walked to the depths of the fish's belly, and finally arrived at a place that Xu Yan couldn't help but be shocked.

Molten Pool, a strange place in the country of sharks.

The molten pool was a wide pool, and there was a strange green water gushing in the pool, and when he reached the vicinity of the molten pool, Xu Yan could feel a corrosive breath coming to his face.

"You can't get any closer, let alone fall in, you'll die!" Xiao Xi was terrified of the molten pool she almost fell into back then, and kept reminding Xu Yan to be careful.

The molten pool is not known how deep it is, and it is located in the stomach of the sea-swallowing whale, which is used to digest all kinds of food swallowed by the sea-swallowing whale.

In the molten pool, which should be a vast ocean, there are strange white boulders, which look like cliffs, connected to the edge of the molten pool, and the top is quite smooth like a stone platform, and there are a lot of hard sand and corals piled up on the stone platform, and some mermaid women are carefully going back and forth to the stone platform, transporting sand and gravel and other sundries.

"This is Longyan, a wind pillar will be formed on Longyan once a year, as long as you stand in the wind pillar, you can leave the sea swallowing whale from the valve with those very hard sea sand. ”

Xiao Xi pointed to the chip-like black sea sand stacked by the merman woman on the rock and said: "This kind of sea sand is the hardest, even the molten pool can't melt, it will form a blockage in the molten pool, and those golden corals are the most hated things of the sea swallowing whales, and the task of our merman clan is to clean up the black sea sand and golden corals, and pile up these things that the molten pool can't melt on the dragon rock, and when the sea swallowing whale opens the valve once a year, it will be sprayed out together." ”

Before coming to the molten pool, Xu Yan could imagine that the task of the merman clan was to clean up some sea sand and the like, but when he saw what the merman clan had cleaned up, Xu Yan was shocked.

"Away from the Golden Coral!"

Looking at the strange black sand and golden coral on the dragon rock, Xu Yan exclaimed, these two kinds of miscellaneous things in the eyes of the mermaids, the garbage that the sea swallowing whale could not digest, have become the famous and best refining materials in the human race immortal cultivation world, and they have no price!

From the golden coral and dragon scale sand, it is the material for refining the best magic weapon, as long as the quantity is enough, it can be refined spirit treasure, which is rare to see in the major markets, but it is regarded as a useless thing in the shark country, and it must be cleaned up every year.

The existence of the golden coral and the dragon scale sand only shocked Xu Yan for a moment, and when Xu Yan's eyes looked at the so-called dragon rock, suddenly the black dragon soul under his eyes let out a violent dragon roar!

The dim black dragon soul has been stuck in his left eye, Xu Yan was afraid that Xiao Hei's dragon soul would dissipate, so he easily did not use the dragon soul in his eyes.

The dragon soul suddenly woke up, Xu Yan didn't expect it, and he didn't know why Xiao Hei was irritable, so he hurriedly calmed it with his heart.

Divine thoughts communicate with the dragon soul, Xu Yan originally wanted to check Xiao Hei's strange appearance, but he didn't expect that once he communicated with the dragon soul divine thoughts, he immediately sensed an indescribable anger surging in Xiao Hei's dragon soul.

Just like encountering a great enemy of life and death, and encountering a thousand-year-old enemy, the anger and hatred surging in the soul of the little black god directly affected Xu Yan.

A bloodshot welled up in his left eye, and Xu Yan's throat let out a low roar, and his eyes were fixed on the lifeless huge rock, as if facing a great enemy.

"What's wrong with you, donkey?" Xiaoxi wanted to pull Xu Yan away, but Xu Yan threw him away and flew up directly.

Gaba Gaba!

Xu Yan clenched his hands, making a crisp sound, and his whole body burst into the breath of the peak of the Yuan Infant, the scarlet left eye was like a fierce dragon awakening, and the surprise of the right eye was full of shock and incomprehension.

Feeling the wrath of the dragon soul, this familiar feeling is like standing in Lingshui City back then, facing the world-destroying river jellyfish.

In that dragon rock, is there a demon clan?

Doubts only floated, Xu Yan didn't have time to think about it, and immediately mobilized the power of the Yuan Infant to suppress the left-eyed dragon soul, if he didn't suppress it, Xiao Hei would control Xu Yan's body and rush out.

The weak dragon soul was enraged by a stone, and such a vision made Xu Yan cry and laugh, but fortunately, Xiao Hei's dragon soul was very weak, and he mobilized the power of the Yuan Infant and gradually suppressed it.

The scarlet in his left eye slowly disappeared, and Xu Yan took a few steps back away from the so-called Dragon Rock.

"Xu Yan, Xu Yan, what's wrong with you?"

The merman princess ran over from a distance, although she had no legs and feet, the speed of the fishtail gliding was not slow, and she quickly came to Xu Yan's side and asked anxiously.

"It's okay, it's okay. Xu Yan waved his hand to indicate that he was fine.

"Was it hit by the copper head? That guy is the most hateful, he knows how to bully others!" Xiao Xi looked indignant, and thought that Xu Yan's hidden illness was related to the first warrior copper head.

"Does the princess know the origin of that piece of dragon rock?"

Suppressing the dragon soul in his left eye, Xu Yan asked uncertainly, Xiao Hei's restlessness was definitely related to Longyan, but he didn't know if it was the relationship between the golden coral and the dragon scale sand accumulated on Longyan, or Longyan itself.

"Legend has it that the dragon rock is sealed with the real dragon god, and the dragon god is immortal, so even the molten pool cannot be melted. ”

Xiao Xi looked at the rocks standing in the molten pool in the distance, and said: "If you want me to see, Longyan must be full of golden coral and black sea sand, otherwise how can it not melt in the molten pool for thousands of years, Longyan is very large, and it is the place where the sea swallowing whale forms an air column every year, I have seen the formation of air pillars many times, just like a flying dragon soaring into the sky, I think this is also the origin of the name Longyan." ”

Xiaoxi has heard a lot of legends of the mermaid clan, but she doesn't know much about Longyan, but every time she comes to Longyan and sees Longyan, she has a very happy feeling and wants to go to Longyan to play.

Princess Merman did often play on Longyan when she was a child, but after almost falling into the molten pool that time, Xiaoxi was too scared to approach the molten pool.

Crunch.

On the shore not far from Longyan, the door of a thatched hut was pushed open, and the old demon king walked out slowly.

"Longyan, it's a very strange place, I remember it was a thousand years ago, this huge stone was swallowed by a sea swallowing whale and finally fell into a molten pool. ”

The old demon king came to Xu Yan and Xiaoxi with his hands behind his back, and also looked at the boulder in the molten pool, recalling: "At that time, I saw the big stone fall in, this stone is very peculiar, not a piece, but coiled into the shape of a long dragon, I thought it would gradually melt in the molten pool, but I didn't expect it to be unmoved for so many years, and then it was called Longyan." ”

"The horse turned out to be a strong man in the human race, and he was clumsy, so he didn't see it for a while, and he was sluggish. The old demon king said, his cloudy old eyes became a little clearer, and the demon king's breath surged, enveloping Xu Yan.
