Underneath the water, a long "waterway" swept through.

This waterway is like a tunnel under the sea, twisting and tumbling, white throughout, very conspicuous.

Before he could get closer, he noticed a strange aura coming from the tunnel, which made his mind tremble.

"There's something strange about this Black Sea!"

It was not the first time that Mo Nan had come to this Black Sea, he had been here when he was an emperor, but at that time, he was a powerful person who was above the heavens and the earth, and he came directly from the Void, and he didn't care much about this Black Sea.

The current Mo Nan can only rely on the strength of the ancient dragon body to forcibly swim through the water.

With his current strength, even if he was suppressed by the powerful coercive force, he could shuttle through the water, and he had already gone from the waterway with just one flick.

When he rushed directly into the waterway, he immediately found that the pressure in it was several times less, which allowed him to catch his breath for a while.

"Is this Reiki?"

Mo Nan's eyebrows raised, he actually felt a surging diffuse aura in it, but unfortunately, he couldn't absorb these aura at all now, so he could only rush forward directly.

"It's ...... Water Cave?"

Mo Nan's eyes widened suddenly, and although his pupils were not fully recovered, they were enough for him to see what was in the water.

That's a huge palace!

It's like the legendary Dragon Palace in mythology!

In front of them were two huge ancient gates, which were only blocked, and wisps of aura emanated from the gates. And what emanates is that incomparably rich aura.

"This is the Water Immortal Mansion...... Which immortal left the Immortal Mansion behind?"

Mo Nan's gaze swept away, and he couldn't finish reading all the immortal mansions, and this immortal mansion was inevitably too big.

Boom!!

At this time, in front of the gate of the Immortal Mansion, a blackened old figure suddenly appeared out of thin air. This figure seems to have been hiding in the water early in the morning, waiting for the prey to appear.

Judging from the long black hair, it was obviously an elderly woman.

As soon as her figure appeared, she grabbed Mo Nan's body violently.

Rumble!

Suddenly, the sea water on the entire sea surface seemed to freeze at this moment, as if she had grabbed it with one hand.

Hmmm-

Mo Nan was shocked, this kind of terrifying power was absolutely impossible for him to resist. He didn't have time to defend at all, and the whole person was grabbed by the long-haired old woman with one hand.

Moreover, it still grabbed his throat straight!

At such a close distance, Mo Nan also saw the appearance of this long-haired old woman clearly at once, and she didn't know what it was on her face, which looked extremely ugly, as if she had goosebumps, and her eyes were also full of indifferent killing intent.

"Little baby, how did you know about this?!" the long-haired old woman's voice was hoarse and ugly.

Mo Nan was experienced in a hundred battles, and he immediately knew what the long-haired old woman wanted to do, and he immediately shouted vigorously: "I was thrown into the sea! I don't know how I ended up in the territory of my predecessors!"

According to Mo Nan's temperament on weekdays, it is impossible for him to say these words, but he doesn't want to die at the hands of this innocent old woman for no reason.

The long-haired old woman glanced at Mo Nan from top to bottom, then threw it, pushed Mo Nan a few meters away, and said hoarsely:

"You didn't even cultivate...... Hmph, then I'll spare your life. ”

Mo Nan was a little crying and laughing, blessings and misfortunes depended on each other, he lost his cultivation and even saved his life.

"Since this is the Immortal Mansion of the seniors, then the juniors will leave!"

"Stop, who allowed you to go?" The long-haired old woman stretched out her hand and took out a piece of snow-white ice, which immediately made the surrounding sea water freeze into pieces.

This terrifying power of the ice path made Mo Nan's blood almost freeze.

"God treats me well, and even sent you such a suitable person...... If you obediently do something for me, I will let you go, otherwise, you will fall again like them!"

Mo Nan followed the long-haired old woman's point, he looked at the water above, and was surprised to find that there were more than a dozen skeletons floating there, and he didn't know how long he had been dead.

"What do you want me to do?" Mo Nan forcibly resisted the cold aura that invaded the bones around him.

The long-haired old woman pointed to the huge gate of the Immortal Mansion, where there was a faint red light, as if it was where the lava was.

"See, I want you to go down and suppress the Holy Heaven Burning Fire below, and when I open the gate of this Immortal Mansion and be able to hold on, you will be able to live." If you can't hold on, you don't need me to kill you, then the Holy Heaven Burning Fire will be able to burn you. ”

Mo Nan's eyes narrowed suddenly, he couldn't imagine that it was the Holy Heaven Burning Fire below, it seems that this Immortal Mansion does not belong to the old woman, she just came to look for an opportunity, but once she opens the door, the Holy Heaven Burning Fire below must be the Burning Sky, and she will be burned to death before she enters it.

"Holy Heaven Burning Fire...... Then how can you just give me a piece of Nine Xuan Ice? You must at least give me Yunlang Sha again, or the Purple Wind Level 8 Defensive Formation Banner!" Mo Nan said suddenly.

As soon as these words came out, the long-haired old woman was stunned.

She glanced at Mo Nan from above, and she was surprised: "Boy, you know a lot! But if I have those things, do I need you to come?

Mo Nan was not in a hurry, he was not afraid that the old woman would kill him now, because she needed to enter the Immortal Mansion, if a person could go in, he would have already gone in, and now that he has come, there is finally a little hope, it is impossible for her to kill.

Mo Nan said with a smile: "It's just Jiuxuan Ice, not only will I fall, but you will definitely be difficult to live alone, even if you save your life, this Holy Heaven Burning Fire will start to burn the sky and boil the sea, and it will definitely attract the powerful people of other great clans...... Hehe, why don't you show me your ring, there is something I can use, so that it can help you. ”

The long-haired old woman seemed to be shocked, it had not been a year or two since she had paid attention to this immortal mansion, and she had met a lot of cultivators, but when there was a cultivator as calm as Mo Nan, it was a kind of calm from the bottom of her heart, not pretentious.

At the very least, none of the people she caught dared to bargain with her for anything else to defend herself against.

This young man knew his situation, he did not plan to escape, nor did he resist, but discussed with her how to crack it, and at the same time, what he said was indeed able to crack the Holy Heaven Burning Fire!

This teenager is anything but simple!

There is no one who has not cultivated to be able to live in this Black Sea!

"Okay-" The long-haired old woman actually agreed, took off a ring hidden in her finger, erased the confinement of the ring, and then threw it to Mo Nan, she has strong self-confidence, Mo Nan will never be able to run away.

Mo Nan didn't hesitate after taking it, and swept it lightly with his divine sense, and found that there were not many things in the ring, but there were a lot of Jiuxuan ice cubes, and there were also some divine weapons, spirit grass, and some pink and bewitching women's clothes......

Flipping through it, Mo Nan found a huge bronze mirror inside.

He knew that this was definitely not an ordinary bronze mirror, and he took it out to take a look, only to find that it was an immortal weapon! There was a faint shadow in this mirror, it was a slender female cultivator, and the previous owner should have been a female cultivator.

"You should be able to try it with this!" Mo Nan nodded with the huge bronze mirror, and then his palm shook down, and the bronze mirror suddenly changed to a size of ten meters, if it weren't for Mo Nan's divine power, he wouldn't even be able to hold it.

"Hurry up!" The long-haired old woman's face sank, and she didn't know what the ugly thing on her face came from, and she looked a little hideous.

Mo Nan grabbed one end of the bronze mirror with one hand, and held the Nine Xuan Ice with the other, and suddenly the entire copper mirror was covered with ice.

He slammed down, and rushed straight down into the flames of the Holy Heaven.

After this sinking, Mo Nan knew that it was bad, this Holy Heaven Burning Fire was several times more powerful than he imagined, and the ice cubes on his body were melted in an instant, and a powerful scorching aura rushed towards his body.

He threw the Nine Xuan Ice in front of him, using the huge bronze mirror to block it.

Bang!

There was a loud roaring sound in Mo Nan's ears, and he was furious in his heart, and he was not ready at all, the long-haired old woman actually began to open the gate of the Immortal Mansion.

The Holy Heaven Incineration Flame below seemed to have been touched by some prohibition, and a huge flame burst out.

A huge heat wave burned the strange waters around it.

All of a sudden, all the surrounding sea water burned into flames!

Mo Nan's body was too small in the huge flames, and he could only shake the bronze mirror again, making him grow up again, stretching into a hundred meters in size.

Buzz –

The rolling flames were suddenly blocked by the bronze mirror, reflecting the surging flames in another direction.

And at this moment, the gate of the huge immortal mansion was suddenly opened......
