Eternal Sacred King

As though it sensed the auras of the thousands of Grotto-heavens outside, there seemed to be a mysterious power flowing on the surface of the Netherworld Treasure Mirror, gradually forming a gray vortex.

Immediately after, a powerful devouring power burst forth from the Netherworld Treasure Mirror!

The Grotto-heaven powers that the Essence Martial Grotto-heaven could not digest immediately were devoured by the Netherworld Treasure Mirror and the pressure on the Martial Dao Prime Body decreased.

That change happened in the Essence Martial Grotto-heaven.

The spirit consciousnesses of Ming Feng and the other Nether King and Hell King experts could not enter the Essence Martial Grotto-heaven that was deep and dark, so they naturally did not know what happened.

Initially, the Essence Martial Grotto-heaven of the Martial Dao Prime Body had already gradually stopped spinning.

At that moment, the Essence Martial Grotto-heaven circulated once more and the devouring power that erupted was even more ferocious and powerful than before!

The range of the Essence Martial Grotto-heaven suddenly expanded!

The expressions of Ming Feng and the ten Territorial Lords changed starkly. They reacted extremely quickly and retreated in a hurry.

However, the group of Hell King experts behind them could not dodge in time and were devoured by the Essence Martial Grotto-heaven. They disappeared before they could even scream!

Because of the eruption of the Netherworld Treasure Mirror, the Essence Martial Grotto-heaven did not just devour the surrounding Grotto-heavens—it even devoured more than a hundred Hell King experts!

That scene caused panic in the eyes of the Hell King experts.

Not only did the dark Grotto-heaven that they surrounded not shatter, it even devoured more than a hundred Hell King experts along with their Grotto-heavens!

Who wouldn't be afraid of such a strange and terrifying scene?

The Martial Dao Prime Body was also observing the commotion here.

His Essence Martial Grotto-heaven had yet to reach that level.

The one who released such might was not the Essence Martial Grotto-heaven, but the Netherworld Treasure Mirror in the depths of it!

The Essence Martial Grotto-heaven could clearly sense that the Netherworld Treasure Mirror had a strong desire to devour the Grotto-heavens and even the flesh of the Hell King experts outside.

The Netherworld Treasure Mirror devoured the power of the Grotto-heavens in large mouthfuls like an extremely hungry ferocious beast.

This feeling was a little similar to the Hell Suppression Tripod back then. In order to repair itself, it devoured and refined many divine weapons and Dharmic treasures.

The Hell King experts did not die after entering the Essence Martial Grotto-heaven. They released their Grotto-heavens and endured with all their might!

Their Essence Spirits, flesh and blood existed and their Grotto-heavens not only contained their Dharmic Daos, but also their powerful wills.

Although the Essence Martial Grotto-heaven had devoured them, it was impossible to refine more than a hundred Hell Kings in a short period of time.

"As long as we hold on and join forces with the Hell King experts outside, we'll definitely be able to destroy his Grotto-heaven!"

"That's right!"

The Hell King experts communicated and tried their best to persevere in the Essence Martial Grotto-heaven.

Right then, an ancient mirror gradually appeared in the depths of the Essence Martial Grotto-heaven.

There was a faint blood glow on the gray mirror.

In the depths of the Essence Martial Grotto-heaven, it was like a single eye that shone with a sanguine light. It was sinister and abnormally terrifying!

The hundred-odd Hell King experts did not dare to move at all after being targeted by that single eye and felt their blood run cold!

An indescribable fear surged into their hearts.

That fear seemed to come from the depths of their souls and bloodlines.

It was as though they should have been afraid of this single eye since they were born!

Initially, under their persistence, they could still maintain their Grotto-heavens by channeling their Essence Spirits continuously.

However, when targeted by that single eye, the hundred-odd Grotto-heavens began to sway and show signs of collapse!

Suddenly!

The ancient mirror transformed into a gray light and streaked around them.

Boom! Boom! Boom!

More than a hundred Grotto-heavens collapsed!

The bodies of the Hell King experts were sliced into two by the gray light as well and fresh blood flowed, forming a blood fog that dyed a large area of the Essence Martial Grotto-heaven red.

As for the Netherworld Treasure Mirror, it seemed to be extremely excited by that scene and charged into the blood fog!

The Netherworld Treasure Mirror was like an ancient behemoth that devoured the surrounding Grotto-heavens in large mouthfuls. In fact, it even devoured the flesh of more than a hundred Hell Kings!

In just a few breaths, there was no longer any blood in the Essence Martial Grotto-heaven.

Just like that, more than a hundred Hell King experts were devoured by the Netherworld Treasure Mirror without a corpse left. There were only a hundred-odd storage bags left floating in the Grotto-heaven.

The Martial Dao Prime Body was secretly alarmed.

This Netherworld Treasure Mirror was way too evil and ferocious.

It had been dormant in Greater Avici for countless years and had awakened after devouring the Grotto-heavens of the various Hell Kings. Now, it was recovering as well.

The power it wanted to absorb in order to recover did not only come from major and minor Grotto-heavens, but also the flesh and blood of Hell Kings!

The Martial Dao Prime Body could clearly sense a powerful and terrifying power gradually awakening in the Netherworld Treasure Mirror.

Of course, even though it had just absorbed the power of many Grotto-heavens and devoured the flesh of more than a hundred Hell King experts, it was far from enough!

On the battlefield.

Ming Feng and the others naturally did not know what happened in the Essence Martial Grotto-heaven in the few breaths earlier on.

However, they could all sense that the dark Grotto-heaven in the center of the battlefield had become even more terrifying, as though a frightening existence was awakening in the depths of the Grotto-heaven!

The devouring range of the Essence Martial Grotto-heaven spread continuously and the devouring power became stronger!

This was the process of a trade-off.

Thousands of Hell King experts summoned Grotto-heavens of various sizes, wanting to suppress the Martial Dao Prime Body.

But now, not only was the Martial Dao Prime Body not dead, the Essence Martial Grotto-heaven obtained the help of the Netherworld Treasure Mirror and devoured more and more, becoming stronger!

Initially, both parties could still maintain a stalemate.

However, as time passed, the power in the Netherworld Treasure Mirror became stronger and stronger. The Essence Martial Grotto-heaven grew gradually as well and the Grotto-heaven power of the thousands of Hell King experts drained rapidly.

Some ordinary Hell Kings with minor Grotto-heavens could no longer hold on.

The Grotto-heavens shattered and even the Grotto-heaven fragments were devoured by the Essence Martial Grotto-heaven. Hundreds of thousands of years of cultivation were destroyed in a single day!

Without the Grotto-heavens, the Hell King experts would lose their greatest reliance and would only have their flesh and Essence Spirits left.

This was no longer devouring—it was plundering wildly!

Right in front of countless living beings of Hell, figures fell from midair one after another.

Many living beings of Hell were shocked!

These falling figures were all Hell King experts who dominated a region and were almost at the peak of the combat strength of the Hell World!

But now, as though they were severely injured, the Grotto-heavens behind them shattered and their Essence Qis were greatly damaged. They fell into the ruins below with weak auras.

Ming Feng's face was pale and fear finally appeared in his eyes.

What kind of monster was this cultivator from the Heavenly World?

Even with thousands of Hell King experts joining forces, they could not suppress him!
