Each aperture is different in color, and the scenery inside is different.

There are green and vibrant; There are huge waves, a vast ocean; There are blazing flames and monstrous seas of fire; There is a golden iron horse, and the intention of killing is agitated; There are towering mountains, and they are extremely thick.

It was Qin Ziling's Five Cave Heavens.

The essence of human immortal cultivation is the ontology, and the most powerful nature is also the ontology.

Therefore, the strongest attack of the Cave Heaven Realm Immortal is his Cave Heaven.

It's just that the Yipin Cave Heaven is still very unstable, the virtual and the real are uncertain, once it is displayed and is broken, it is the foundation that is destroyed, and years of hard work have been in vain.

And it takes time for the cave to be unleashed.

Therefore, under normal circumstances, human immortals would not perform the Cave Heaven Secret Technique.

But today is different.

Qin Ziling insisted on killing Elder Yan!

And Elder Yan was trapped in the sword formation, and was suppressed by the thunder, so he chose to be on the defensive and did not take the initiative to attack, which gave Qin Ziling the opportunity to accumulate the power of the Cave Heaven.

The five cave heavens slowly rose one after another, exuding a terrifying aura of power.

"Five Cave Heavens!"

Seeing this, Elder Yan's face changed slightly, and his eyes showed shock, but he did not change his strategy.

Although the power aura of the five caves was powerful and the number was terrifying, it did not pose a great threat to him.

His first biggest threat was from the Printing and Dyeing Moon, followed by the Jiuding Fire Raven Sword Formation.

One is the strongest attack, and the other is the strongest block.

But the five cave heavens are still much worse, and the power of each one is only equivalent to a relatively powerful four-rank true immortal.

And he is a six-rank true immortal.

If it weren't for the fact that he was now trapped in the sword formation and suppressed by the thunder, he would be able to break them one by one at will.

But soon, Elder Yan's face changed again.

Because the five caves are together, not only that, but there are scenes projected in distant places in the caves.

There were mighty rivers, towering mountains, and vast plains.

The scenery gradually became clear from the blur in the distance, and finally completely merged with Qin Ziling's cave sky, and it was not clear which were Qin Ziling's original scenery and which were the scenes projected in.

As Qin Ziling's cave sky and the projected scene gradually and completely merged, a heavy sense of coercion emanated from the cave sky behind Qin Ziling's head.

This coercive aura continued to rise, and soon broke through to the fifth-grade true immortal level, and then continued to climb, but soon stopped climbing, and finally stopped at the fifth-grade true immortal level, unable to break through to the sixth-grade true immortal level.

Seeing this, Elder Yan secretly breathed a sigh of relief.

But at this moment, Qin Ziling's eyes showed a touch of ruthlessness.

Then, Elder Yan saw that the mighty rivers in the Cave Heaven World were gradually drying up, and the towering mountains were collapsing down, and there was blood light rising to the sky in the west, and the blood color filled the west side of the Cave Heaven......

With these changes, the majestic and heavy aura of the cave sky seemed to suddenly break free from its shackles, and suddenly climbed to the level of a six-rank true immortal, and it was even climbing.

Elder Yan's face changed drastically.

"Boom!"

But at this moment, the Cave Heaven World that Qin Ziling had manifested had already crushed the void and fell towards the black knife curtain.

Almost at the same time, under the urging of the immortal power, the Wind Thunder Mountain Seal also rumbled towards the black knife curtain.

There were also fire crows that suicidally slammed into the black knife curtain.

"Boom!"

The black knife curtain collapsed, revealing the Black Hell Demon Knife.

"Boom!"

A thick thunderbolt slashed through the air the moment the black knife curtain collapsed.

The white bone claws put their five fingers together, and blocked the thunder with their vertical palms.

At this time, Qin Ziling's cave heaven fell swiftly towards Elder Yan.

The repulsed Black Hell Demon Knife made a sharp sound, and suddenly turned into a black light and rushed over, trying to slash Qin Ziling's Cave Heaven.

However, Qin Ziling had already calculated this.

The Wind Thunder Mountain Seal fell, blocking the Black Hell Demon Knife.

The Wind Thunder Mountain Seal was Qin Ziling's sacrifice with the power of the Immortal Family, and it stands to reason that he can't block the blow of the Six-Rank True Immortal.

However, this Black Prison Demon Knife had been severely injured just now, and now it was hastily transferred back to the Protector, its power was limited, and it was forcibly blocked by the majestic Wind and Thunder Mountain Seal.

Elder Yan was helpless, and the immortal power frantically penetrated into the Python Immortal Clothes on his body.

The fairy clothes agitated, and the runes shone.

The black python coiling around Elder Yan continued to expand, appearing larger and more vicious.

"Bang!"

The cave sky fell.

The black python was smashed all of a sudden, turned into a little ghostly light, retracted into fairy clothes, and solidified into runes.

The rune glows dimly.

"Poof!"

Elder Yan burst out with a mouthful of blood, and his entire aura suddenly withered and weakened.

He's hurt again!

However, Qin Ziling and Yin Dye Yue would not relax just because Elder Yan was injured, and slowed down their attacks.

On the contrary, they knew that Elder Yan was powerful, and it was easy to defeat and trap him, but it was extremely difficult to kill him in a short period of time.

Therefore, it is necessary to take advantage of his illness to kill him!

"Boom!"

One after another, thick thunderbolts kept falling.

The white bone claws continued to resist, and they retreated, and cracks appeared on it.

"Boom! Rumble! ”

"When! While! ”

Qin Ziling's Cave Heaven and Mountain Seal also continued to attack Elder Yan, but they were blocked by the Black Prison Demon Knife.

When Dongtian continued to collide with the Black Hell Demon Knife, in the Dongtian World, at this time, there was already a landslide and the earth was cracking, and the magma of the earth spring was gushing, as if the end of the world was coming.

The river is drying up, and the blood in the blood pool to the west is dwindling.

Only at the head of the Longyuan River, the area of Qianlong Mountain is guarded by an invisible force, and it is still calm and full of vitality.

This was Qin Ziling forcibly absorbing the energy in the Cave Heaven World to fuel his Cave Heaven, causing his Cave Heaven power to skyrocket to the level of a sixth-grade True Immortal all of a sudden.

Of course, this comes at a great cost!

The cave world is shattered and shrunk!

However, at this time, Qin Ziling couldn't take care of these things, otherwise, once Elder Yan left, not only would his previous achievements be wasted, but he would also have endless troubles.

Elder Yan miscalculated one after another, he had already suffered two heavy blows, and now he was equivalent to facing the two sixth-grade true immortals alone, and he was also trapped in the sword array, and he needed to be on guard against the attacks launched by the sword array at all times, and the situation became more and more dangerous.

His hair was scattered, his eyes were blood-red, and the python fairy clothes were stained with blood.

The immortal power penetrated into the white bone claw and the black prison demon knife like no money, constantly attacking towards Yin Dye Yue and Qin Ziling, and the immortal power around him rotated sharply, changing into various whirlpools and blades to resist the flame attacks launched by the sword array.

Attack is the best defense.

Now, it was no longer possible for Elder Yan to hold on and delay time as before.

He could only resist the enemy's tough attacks with a tough attack, and it was possible to delay until the Fire Abyss Forbidden Land was closed.

Otherwise, if he blindly defends and is beaten, he will definitely die.

The fighting between the two sides became more and more intense.

Qin Ziling's cave sky continued to smash down, and a trace of cracks faintly appeared, and the scene of the cave world became more and more broken, but it also smashed the black prison demon knife again and again, the sword was scattered, and Elder Yan was even more churning, and the immortal babies in the immortal mansion trembled all over, and kept shrinking.

The Purple Sky Thunder Staff has turned into an Optimus Pillar, standing between heaven and earth.

Yin Dye Moon stood on top of the giant pillar, the whole person was full of lightning, and the lightning symbol in the center of the eyebrows shone more and more, like the god of thunder coming to the world.

She kept pinching the spell with her hand, and one after another purple electric dragons rushed out of the Optimus Pillar and killed Elder Yan, causing cracks to appear on the white bone claws, and the electric sparks in the cracks crackled and flashed.

The power of the thunder and lightning was transmitted to Elder Yan along the white bone claws, causing electric snakes to swim around from time to time, and the hair that had been scattered rose to the sky from time to time, looking extremely embarrassing and ridiculous.

Half a day passed in a tragic battle.

Elder Yan's face was as pale as paper, and his immortal clothes were covered in blood and tattered.

The Black Prison Demon Knife was dim, and the white bone claws were full of cracks, as if they were about to collapse at any moment.

"Click!"

Another bolt of lightning struck down, and a white bone claw snapped.

"Poof!"

The magic weapon was hit hard, and Elder Yan felt like someone had been hit hard in the heart, and he couldn't help but grab another mouthful of blood, and the immortal babies in the immortal mansion trembled all over their bodies and kept shrinking.

At this time, Qin Ziling's cave sky fell like a star again, smashing on top of the Black Hell Demon Knife.

"Dang!"

The Black Prison Demon Knife fell sharply.

Elder Yan burst out of his mouth with another mouthful of blood, and his whole person became more and more depressed.

Seeing this, Qin Ziling and Yin Dye Yue were overjoyed and launched a more fierce attack.

They knew that Elder Yan wouldn't be able to support it for long.

Elder Yan's eyes radiated a desperate and frantic gaze.

"Haha, if you want to kill me, you will all have to pay a heavy price!" Elder Yan laughed wildly, his face hideous and terrifying.

Then his plump body continued to shrink and shriveled, and his skin, which was still round and smooth, became dry and old, crawling with wrinkles and age spots.

Years and vitality were passing by on him at a speed visible to the naked eye.

As the years and vitality passed, a black and gloomy aura of death poured out from Elder Yan's body, turning into a black python coiling around Elder Yan, the neck of the black python poked out from behind Elder Yan, and the huge python head overlooked the four directions.

The python's eyes were lifeless, and when he looked down, it was as if death was looking down on all living beings mercilessly.

The python's mouth suddenly opened.

When this mouth opened, it was like a void suddenly opening the gates of hell, and inside it was endless darkness and death.

The overwhelming fire crows rushed in, and all at once they were reduced to nothingness and darkness, and there was no movement at all.

The thunderbolt struck in, and it was only like a match in the darkness, and it was quickly extinguished.

Streams of invisible death power were released from the "Gates of Hell", constantly devouring and ingesting the life around them.

"Be careful, this is the Netherworld Mansion's Hell Devouring Secret Technique, which can devour all life, Brother Ziling, quickly withdraw from the sword formation!" Lei Xiao suddenly spoke, and then the Optimus Pillar disappeared, turning into a purple electric dragon that coiled the dyeing moon tightly.

Thunder and lightning flickered around him, trying to isolate death from it.

"Haha! This technique has been performed, how can I let you escape? Elder Yan laughed maniacally.

The Black Prison Demon Knife had already sealed Qin Ziling's retreat, while the White Bone Claw had locked on to the Printing and Dyeing Moon, preventing her from supporting Qin Ziling.

Thank you for the shore of the heart, the divine light of autumn, and the waiting of ten thousand years for the reward of book friends.
