However, these lifeless black mist ghost soldiers could not sense the terrifying power contained within the Raging Sea Heavenly Nether Holy Sword, nor could they feel fear.

They continued to take lifeless strides, closing in on Alex and launching a fierce attack.

"Myriad Waves Thousand Army Breaker!"

Alex was expressionless as he unhurriedly swept his sword outwards. Centering on himself, he summoned streaks of monstrous, sky-high waves that swept out in all directions.

Within these massive waves, not only was there majestic water elemental power, but they were also mixed with a terrifying sword intent.

The instant they touched the crashing waves, the black mist ghost soldiers were directly evaporated, lacking the slightest power to resist.

"Such a powerful water technique!" Facing these monstrous flood waves that carried the momentum to sweep aside a thousand armies, the Nether Earth Ghost King and Bright Candle Ghost King revealed looks of terror.

Not daring to resist, they directly teleported backward to dodge.

However, the Heavenly Fiend Ghost King had just been controlling the black mist ghost soldiers, making his movements a fraction slower.

In just that split second of hesitation, dozens of massive waves had already swept right before him, like giant beasts opening their bloody maws, intending to swallow him whole.

Unable to dodge in time, he had no choice but to summon a semi-circular black mist shield to defend.

But this tiny shield, in front of the myriad high waves, could not even be considered an umbrella.

"Ah!" As the giant waves crashed down, the Heavenly Fiend Ghost King instantly felt the oppressive force of millions of tons and let out a miserable, shrill scream.

From his eye sockets, nasal cavity, and ears, pitch-black blood continuously seeped out.

This proved that under the terrifying pressure of the massive waves, the ghost heart and meridians within his body had all been forcefully crushed until they ruptured.

Having presided over the Hundred Ghost Mountain Range for thousands of years, the Heavenly Fiend Ghost King had tortured and killed so many mortals and slaughtered so many villages that even he could no longer remember.

Someone once asked him how much mortal blood essence he had devoured in total since his birth.

The Heavenly Fiend Ghost King merely waved his hand and smiled cheerfully. "Do you remember how many pieces of bread you have eaten?"

When he was cheerfully dropping that line back then, the Heavenly Fiend Ghost King never imagined that one day he would actually be like an ant in a pouring rainstorm, fundamentally unable to withstand the sky full of raindrops, completely despairing and powerless.

And moreover, this despair came from a human, the very race he despised the most.

"Tsk tsk, how exhausting." Alex smiled with interest.

"Forget it, I will just lend you a helping hand."

With that, Alex unhurriedly raised his hand, lifting the Raging Sea Heavenly Nether Holy Sword above his head.

The myriad giant waves devastating the Heavenly Fiend Ghost King seemed to instantly receive an order.

They released the prey in their mouths one after another, uniformly converging in midair.

Freed from the confinement, the Heavenly Fiend Ghost King was powerless to flee, lying paralyzed on the ground at his last breath. He struggled to raise his head and focused his gaze, instantly becoming dumbfounded.

The giant waves converged in midair, condensing into a myriad long water dragon.

The sword intent permeating its body actually transformed into dragon might, causing all living creations to tremble before it.

The Heavenly Fiend Ghost King swore that this was the most spectacular water technique divine ability he had witnessed in his tens of thousands of years.

So much so that, facing the approach of death, he could not even feel fear, only letting out continuous, relieved, miserable laughs.

"Sea God Tyrant’s Judgment!" Alex let out a booming shout, swinging his sword to point at the Heavenly Fiend Ghost King.

It was exactly identical to the action the Heavenly Fiend Ghost King had used when pointing at him and controlling the ghost soldiers to attack.

It was just that the oppressive feeling of this tyrant water dragon that blotted out the sky and sun was far stronger than those few minor ghosts materialized from black mist.

With Alex’s command, the water dragon crashed down with a boom. It directly opened its bloody maw and swallowed the Heavenly Fiend Ghost King whole.

A deafening dragon roar echoed through every corner of the world.

"Tsk, truly worthy of being the treasured sword that could cleave a Saint-level bloodthirsty Demonic Flood Dragon into two segments with a single strike." Alex examined the holy blade in his hand, smiling in satisfaction and nodding.

"Not bad, this weapon is even handier than the Vault of Divine World-Destroying Sword. Furthermore, before every use, there is no need to waste spiritual energy to execute the Six Paths Wheel of Destruction Technique."

Standing on a nearby cliff to take shelter, the Nether Earth Ghost King and Bright Candle Ghost King could not help but shiver in panic.

"Old Man Nether Earth, tell me the truth..." The Bright Candle Ghost King said with a complicated expression.

"Do you think we Four Great Ghost Kings have lived too long, so you deliberately brought us here to die? If not, why were you so stubborn, insisting on making an enemy of this kind of monster?"

Facing the Bright Candle Ghost King’s questioning, the Nether Earth Ghost King remained silent.

Watching the Heavenly Fiend Ghost King be obliterated into ash, leaving only a wisp of yin qi remnant soul that Alex unhurriedly stored into a jade slip, he could not help but gulp down saliva, saying hoarsely.

"It is not that this old man wanted you to die. It is heaven’s decree. The destiny of our Four Great Ghost Kings has come to an end..."

"Oh?" Alex seemed to have heard the Nether Earth Ghost King’s words, he unhurriedly turned his head to look in their direction, a meaningful smile curling at his mouth.

"To actually call me destiny? The Nether Earth Ghost King flatters me too much."

The next second, Alex’s figure vanished from his spot.

The two Great Ghost Kings froze slightly, sensing a chilling astral wind.

The next second, Alex directly, without any warning, appeared behind them!
