The god and demon powerhouse left a breath and asked Ling Yun to follow him.

Ling Yun didn't slack off, and along the way, he also communicated with the ancestral dragon in the ancestral dragon hall.

But it's still any news from Zulong.

It's as if the ancestral dragon didn't exist at all.

This couldn't help but make Ling Yun miss Lao Yan a little.

Although Lao Yan is a little unreliable.

But almost on call.

It's just that I don't know where Lao Yan took Xiao Jiu to, so nothing should happen.

After a little muttering, after a while, Ling Yun followed the aura of the mysterious powerhouse to the sky above a sea area.

The topography of this sea is very special.

It's like a basin.

The surrounding waters are much higher.

And the further you go to the center, the lower the water.

And in this sea basin, there are several vortices.

Those vortices are huge.

It's as if a drill can go to the bottom of the sea.

Just looking at it from a distance gives people a sense of horror.

Even those sea beasts that came here before, I am afraid that they would never dare to approach those whirlpools.

Once swept down by the vortex, there may be no bones left.

"Little one, do you see those swirls?"

The voice of the god and demon powerhouse rang out.

"See. ”

Ling Yun nodded.

He wasn't blind, so how could he not see those few fierce whirlpools.

"It's the Dragon's Cave. The Dragon Slayer Balls are under those swirls. You choose one to jump into. If you don't dare, leave the Sea of Dragons as soon as possible. ”

The mysterious powerhouse is very straightforward.

"Senior, the kid is not afraid. It's just that the kid has never seen the Dragon Slaying Ball, if I wait for me to go down, how can I be sure of the existence of the Dragon Slaying Ball?"

Ling Yun asked suspiciously.

Figure it out, and you won't be confused when you go down.

"You little guy is very thoughtful. But you don't have to think about it so much at all, because the old man has only heard of the Dragon Killing Ball, and he doesn't know what the Dragon Killing Ball looks like. ”

"So if you dare to go down, go down and find it yourself. ”

"Good luck. ”

The mysterious powerhouse replied.

This answer made Ling Yun a little embarrassed.

You don't know what Dragon Killer Ball looks like?

Then what else are you taking me to find the Dragon Killing Ball?

Don't you even dare to go down?

Also, how did you know that the Dragon Killing Ball was very useful for entering the Dragon Palace?

Questions came to Ling Yun's mind at once.

But.

This mysterious powerhouse saved his life, and there must be no need to go to such great lengths to deceive himself.

"Good. ”

Ling Yun nodded, didn't ask anything more, and as soon as his heart sank, he jumped directly towards a whirlpool.

And when he jumped down, the voice of the mysterious powerhouse sounded in his ears: "The old man will only wait for you here for half a day, if you can't find the Dragon Killing Ball within half a day, and you don't come out of the dragon cave, then the old man won't care about you anymore." ”

"Life or death is up to you. ”

Really...... It's a little ruthless.

However, Ling Yun didn't think much of it.

Half a day?

You will definitely be able to find the Dragon Slayer Ball and come out of this so-called Dragon Cave.

Jumping into the whirlpool, with the flow of water, Ling Yun's body continued to fall down, and the whole person was dizzy.

However, Ling Yun struggled to keep himself awake.

Try to keep your body in a steady descent.

But these efforts.

It quickly turned into a bubble.

Because the vortex momentum is too big.

It's so big that Lingyun doesn't have an ego at all.

I can't control my body at all.

To be on the safe side.

Ling Yun had no choice but to light up the battle dragon body.

In the case of the battle dragon body, Ling Yun became much better.

At least.

The eyes are no longer dazzled, and the waist is no longer painful.

I didn't feel much when I fell dozens of meters in one breath.

That's it.

After a period of falling, Ling Yun's body slammed into the bottom of the vortex, smashing the entire ground into turmoil.

Ling Yun turned into a human form, because he had just slammed down, although he was not seriously injured, but it also made his qi and blood very disordered.

Therefore, Ling Yun spent a little time and used the recovery technique of all things to breathe.

After the pranayama was finished, Ling Yun looked around.

only to find that this place is really a cave.

It was obviously in the deep sea, but Lingyun's location was indeed a cave, and there was a water curtain above this cave, and that water curtain was actually isolated from the sea water outside.

Even the whirlpool of water washed down did not shake the curtain of water for half a minute.

But.

Ling Yun also found a lot of white bones around.

Many of these white bones are actually ...... Joist.

It's just that the owner of those dragon bones seems to have been dead for a long time, so those dragon bones no longer have any essence and fluctuations.

Even if Ling Yun just moved, attracting the air circulation around him, just a little movement, and some of the white bones around him directly turned into ashes.

But that's not the main thing.

What's more, at the end of the depths of this cave, Ling Yun found a huge stone door.

The stone gate exudes an ancient and decaying atmosphere.

It seems to have gone through the vicissitudes of the sea and the baptism of countless years.

At this time, the stone door was halfway open.

Faintly, you can see that behind the stone gate, there are dragon skeletons.

"This is the Dragon Cave? Could it be the burial place of the dragons?"

Ling Yun was shocked in his heart.

But judging by the way this place looks, this place must be a long time ago, right?

Could it be the Dragon Cave of the Ancestral Dragon Period?

But it doesn't matter.

Ling Yun had better find a way to find the so-called Dragon Killing Ball first.

Otherwise, once half a day passes, that mysterious powerhouse will really leave, and even if Ling Yun has the Dragon Killing Ball, he won't know where to find the Dragon Palace.

Dragon Killer Ball, as the name suggests, is a kind of bead, right?

So Ling Yundang searched for it even in this cave.

And when Ling Yun searched the entire cave mansion, he didn't find anything related to beads.

Not only was there nothing related to beads, but Ling Yun didn't find anything strange at all.

This shows that the so-called Dragon Slayer Ball is not in this cave.

So Ling Yun immediately set his eyes behind the stone gate.

Only that is the most likely Dragon Slayer Ball.

Ling Yun didn't waste time, and walked directly behind the stone gate.

It's just that when there was still some distance from the stone gate, Ling Yun suddenly stopped.

Even his brow tightened a little.

Then Ling Yun barely stopped, and his body retreated as fast as he could.

It was at the moment when he retreated.

A wave of light suddenly shrouded through the stone door.

All of a sudden, the stone gate was enveloped in it.

And that light wave was exactly the same as the light wave that Ling Yun had seen on that small island when Ling Yun had obtained the Eternal Fruit.
