The passage to the Uncharted Realm cannot be opened.

In other words, the previously envisaged retreat has now failed.

This is obviously not good news for Zhou Fan today.

As the saying goes, blessings are incomparable, and disasters are not singular.

Just as Zhou Fan frowned and secretly thought about a solution, he found that the "Purple Mist Cloud Sea" below suddenly began to surge violently, as if something was about to appear!

The next moment.

I saw a purple-winged demon beast several meters in size, inciting its wings to rush out of the poisonous fog quickly!

The purple-winged demon beast resembles a bat, and due to the long-term erosion of venom, its body is covered with pus, and a large amount of purple pus oozes from it, looking very disgusting.

For Zhou Fan, who was standing at the entrance of the cave, this purple-winged demon beast didn't pay attention to it at all, his purple pupils were a little flustered, and he desperately fled upwards against the "poisonous rain" in the sky.

"What's going on?"

Just when Zhou Fan was puzzled, he realized that this was just the beginning.

As if lighting the fuse, I saw that the purple mist below was constantly surging, and dense poisons quickly drilled out of it, including poisonous pythons the size of buckets, toads the size of grinding discs, and purple-backed centipedes dozens of meters long......

Who would have thought.

Even in such a grim environment, there are still so many poisons alive at this time.

These guys don't know what to live on, it's just unbelievable.

But now is not the time to think about that.

It looks as if they are being chased by something, completely oblivious to their own existence, and they are just fleeing frantically along the mountain wall.

Although I don't understand what the situation is.

But when things go wrong, there must be demons, Zhou Fan's eyes were staring at the purple mist sea below that had returned to calm, and a touch of crisis suddenly appeared in his mind, the spiritual power in his body was no longer retained, and the light of the domineering divine armor instantly brightened to the extreme.

Just as he prepares, the entire cave... No, it should be said that the entire underground world suddenly began to shake!

The next second.

"Aang!"

A majestic and ancient dragon roar suddenly came from the depths of the earth!

The moment the sound sounded, the space seemed to freeze, and the poisonous rain dripping from the sky was still in the air, and the poisonous substances that had no time to escape were all frozen in place!

Zhou Fan, who was hiding in the cave, also did not escape, covering his head with a painful expression, only to feel as if his mind was being stirred by an invisible big hand, and blood was oozing out of his mouth, nose, eyes and ears!

【Ding! Attack from the "Nine Mysterious Dragons", EXP +1000]

This roar seems to be only aimed at the divine soul, the defense of the domineering divine armor, and it has almost no effect!

I don't know how long it has been.

The dragon's roar finally dissipated.

When the first drops of poisonous rain fell again, the solidified space gradually returned to normal.

But the poison is unlucky.

Before they could regain their mobility, they fell from above and smashed straight into the stone wall and turned into a puddle of foul-smelling flesh.

"Nine Shadows Dragon?"

Shaking his somewhat dizzy head, Zhou Fan glanced at the prompt that popped up in the system, recalling what happened just now, and there was still a trace of palpitations in his eyes.

Could it be that at the bottom of this Dan Prison, there is still a real dragon imprisoned!

With just one roar can have such power, although I don't know what kind of terrifying existence the other party's true body should be, but it is conceivable that it is definitely not the current self that can resist!

No wonder that Tianba guy repeatedly told him not to go to the bottom.

If there really is such a monster down there, as long as the brain is not broken, I am afraid that it will not be easy to set foot in it.

The dragon's roar came suddenly, and it disappeared very suddenly.

When he was almost recovered, Zhou Fan looked at the poisonous corpses that had accumulated again at the entrance of the cave, and suddenly shook his head helplessly, and swept them all down with a palm wind.

I don't know how Danfeng's group of guys did it, they actually let such a terrifying creature survive here, aren't they afraid that the other party will forcibly break out of Dan Prison?

However, no matter what the above people think, it is not their turn to be a small Open Pulse Realm cultivator.

After waiting silently for a moment, making sure that the dragon's roar should not sound again for the time being, Zhou Fan withdrew his solemn gaze.

Turn around and return to the stone cave and try to enter the Taixuan Realm again.

Not surprisingly, it still ended in failure.

Although I am a little depressed about this, it is useless to complain about it.

Although I don't know if the secret realm passage is affected by the "Nine Mysterious Dragons" below, it has never been able to open.

But with his strength right now, even if he knows the truth, it is estimated that there is no way to solve it.

"No matter, even if you can't enter the secret realm, you have to take the risk and give it a try!"

After a slight hesitation, Zhou Fan looked at the Ning Yuan Dan in his hand, and his eyes gradually became firm.

The successive accidents have made him feel a little uneasy in his heart.

Now that you are in danger, you must improve your strength as soon as possible.

The only thing to be thankful for is that although he was imprisoned here, he was not like the death row prisoners of the White Bone Venerable, at least the storage ring was not forcibly collected.

Consciousness entered the Qianyuan ring on the thumb and came to a large pile of "sundries".

These are all the results of his killing of enemies, and there are all kinds of things in it, and because he is too lazy to distinguish them, they are simply piled up here.

After "rummaging" for a moment, he quickly took out several delicate array disks from them.

Although I don't remember who made it, just looking at the intricate patterns engraved on the array plate, it is obvious that the grade will not be too low.

Stuffing the immortal jade into the array plate, several light curtains soon lit up one after another, firmly sealing the position of the cave entrance.

However, under the erosion of erysipelas, these light curtains were soon dyed with a layer of purple, and even a slight crack appeared on the array disk, which must be unable to support it and will be scrapped soon.

Zhou Fan saw this, but he didn't care.

Anyway, these things are free, and it doesn't hurt to use them at all now.

He took out hundreds of high-grade immortal jade at random and spread them on the ground of the stone cave.

The next cultivation will inevitably require the consumption of a large amount of spiritual energy.

However, the aura in this place has been contaminated with erysipelas, and it must not be absorbed and used, so it can only find another way.

At this time, as a large amount of immortal jade was taken out, a rich aura emanated out, and the remaining erysipelas in the space were immediately dispersed, and the originally cold stone cave also inexplicably added a trace of warmth, and for a while even made him have the illusion that he had escaped from the Dan Prison and was now in the outside world.

If someone else sees this scene, they will definitely scold him for being a loser.

After all, the top-grade immortal jade is so precious that it is reluctant to use it in ordinary times, let alone use it for cultivation!

However, the current situation is special, and there is no other way, anyway, with his current net worth, he can afford to waste a little.

After making sufficient preparations, Zhou Fan sat directly on top of the immortal jade, and without hesitation, he directly took out a three-pattern Ning Yuan Dan and swallowed it on his neck!

Rumble!

The spiritual power in the dantian rioted instantly!

The violent medicinal power was like a rushing wave, carrying him towards a higher level of life!

Meanwhile.

The surrounding poisons seemed to be attracted by some kind of attraction, and they all opened their scarlet eyes and gathered around the direction of the stone cave.

Fortunately, the formation exuded bursts of coercion, causing them to only dare to linger outside the cave, and the scale armor scraped against the ground, making bursts of scalp-numbing "rustling" sounds.

However, as the poison accumulated, the fear of the formation gradually began to weaken.

One of the crimson scorpions moved forward tentatively with a giant scissor-like pincer.

However, just as he approached the range covered by the formation, a sword blade composed of spiritual energy broke through the air!

The seemingly sturdy carapace has no effect, just like a piece of paper being easily pierced and nailed to the ground!

But the crimson scorpion didn't die, and let out a painful roar from its mouth.

As it struggled, the foul blood splattered out, making the poisons around it even more agitated.

Finally at a certain point. The desire for flesh and blood completely overwhelms the instinctive fear.

Countless poisons couldn't be suppressed, and they rushed madly in the direction of the stone cave!

Rumble! Rumble! Rumble!

The formation laid down by Zhou Fan was instantly activated.

For a moment, the sword light and sword shadow, the fire and thunder, countless attacks were merciless, blasting towards any poison that stepped into the attack range!

In just one round of attacks, the hundreds of poisons that ran at the forefront were cleared, and after dropping large pieces of broken and charred corpses, the poison group was temporarily repelled by the formation.

But they didn't give up, seeing that the strong attack couldn't work, they immediately opened their hideous mouthparts, standing in the distance and spewing out Dao venom, obviously they also have a certain amount of wisdom!

Zizi!

The venom fell on the light curtain, and suddenly made a violent corrosive sound, and the originally stable light curtain began to dim.

However, if it continues like this, it will still take a long time to break through the formation.

Just as the two sides were at a stalemate, those powerful poisons in the distance began to gradually arrive.

"Hiss ......"

In the thick purple mist, a pair of huge pupils like lanterns lit up, and I saw a poisonous python with a fleshy horn on its head winding out of it, and the poking out head alone was the size of a truck, exuding the aura of a demon beast that belonged to the Ning Yuan Realm!

Everywhere they went, the nearby poisons retreated.

If you don't have time to dodge, you will be crushed into pulp on the spot by its huge size!

"Hiss ......"

The unicorn python spat out a snake letter several meters long, and its diamond-shaped pupils stared at the cave, and was about to attack, but its body suddenly stopped, and the huge snake head looked in another direction.

"Chirp!"

With a roar.

I saw that under the cliff, a monster with a scorpion body and eagle head slowly crawled out, covered with purple-black scale armor, and its huge body was not inferior to the one-horned python, and its sharp long beak quickly poked out, and a poisonous scorpion several meters in size next to it had no time to react, and the whole head had been bitten and swallowed by it!

Judging from the powerful aura it exuded, it was another poisonous beast of the Ning Yuan Realm!

And that's not all.

There was another rapid flutter of wings in the air, and an ice cicada with a blue body flew out of it.

Compared with the unicorn python and the eagle-headed monster bird, the size of the ice cicada is no more than the size of a basin, but the aura it emits is not weak at all.

Everywhere I went, even the poisonous rain in the air was condensed into ice particles!

All the poisons that were close to each other had no room for resistance, and they were frozen into ice sculptures one after another!

At this time, the three beasts gathered outside the cave, scattered in three directions, looking at each other, and seemed to be quite jealous of each other.

That's when it happened.

A strong aura fluctuation erupted in the stone cave again!

The three beasts turned their gaze at the same time, staring at the stone cave shrouded in the formation, their eyes revealing a humanized desire.

After a short pause.

The strongest unicorn python took the lead in attacking, and its huge body rampage, like a speeding train, shook the mountains everywhere it went, and crashed straight into the direction of the cave!

It seems that he obviously wants to rely on his body type to break into it!

However, it somewhat underestimated the strength of the formation.

Although it was just a random selection, the formations laid out by Zhou Fan were not low-level!

At this time, it was subjected to the full impact of the unicorn python, and it only stabilized after shaking violently.

At the same time, two giant swords condensed out and shot towards the unicorn python that had no time to dodge!

Burst!

In the face of the power of the formation, even the unicorn poisonous python that had reached the Ning Yuan Realm was unable to resist, and the two blades pierced deeply into the snake's body, bringing up a wisp of purple blood!

"Shhh

When the injured unicorn python was in pain, not only did it not flee, but it was completely aroused to be ferocious!

I saw it entrenched in its body, and when it opened its mouth, it spewed out a foul-smelling venom!

A few drops of venom fell to the ground, and even the hard stones were corroded out of a pothole the size of a basin, which was enough to imagine the poison!

Under the erosion of the venom, the formation suddenly began to flicker violently, and the aura contained in it was being rapidly consumed.

Seeing this, the other two beasts were not to be outdone, and joined the battlefield one after another.

The ice cicada shook its wings, and several ice cubes shot out, and the cold raged, freezing the entire stone cave and even the formation!

The Hippogriff opened its mouth and let out a scream, and an invisible sound wave spread out!

However, this move is not bad against living things, and it is obviously a little unwise to use it in an attack formation.

The powerful sound wave not only did not have any effect on the formation, but instead shook the unicorn python and the ice cicada to the ground, and the attacks they sent out were also crooked to the side!

"Shhh

"Squeak!"

Under the angry gaze of the two beasts, the eagle-headed beast hurriedly closed its mouth, and had no choice but to step forward on the scorpion leg in person, and resist the attack of the formation, and the long beak pecked the light curtain!

The thick carapace defense was extremely strong, and neither the sword nor the lightning strike could hurt it in the slightest!

In the face of their coordinated attacks, the most layered formation was quickly broken!

Seeing this scene, the eyes of the three beasts suddenly showed a look of joy, and the attack they sent out became more and more fierce!

Inside the cave.

I saw Zhou Fan still sitting in place with his eyes closed.

There was an empty jade bottle scattered around him, and the second bottle of Ning Yuan Dan was placed aside, and half of the pill in it had also been used!

This is already the thirteenth attempt to break through the bottleneck!

He was naturally aware of the movement coming from outside, but now it was a critical moment for a breakthrough, and he didn't pay attention to it at all.

"Break it for me!"

There was a burst of shouts in his heart, and the bottleneck that had been loosened finally couldn't hold on and shattered!
