Arthas, seeing this, was equally unwilling to be outdone, his undead fire in his skull burning intensely.
His entire being transformed into a monster, slightly smaller than Liu Haotian, with twelve arms, a tail, and sharp claws.
Both monsters, originating from the dark abyss, possessed colossal bodies spanning tens of thousands of miles…
Even the slightest movement from them was enough to cause cataclysms in hell, capable of devouring millions of lives. Every action was as terrifying as a natural disaster.
Let alone the destructive power of the aftershocks when both went all out, unleashing various world-defying skills.
The death rate of the billions of demons and trillions of undead fighting each other was less than the number of beings shaken to death by the aftershocks of the battle between these two monsters, Liu Haotian and Arthas.
In the eyes of the billions of demons and trillions of undead, these two monsters from the dark abyss were like the embodiment of death.
At this moment, as far as the eye could see, the entire world seemed to be covered by the colossal bodies of these two monsters, even dimming the sun.
Liu Haotian, controlling his true demon king form, unleashed his devouring domain to its fullest, wielding the thousand-mile-long Hrognir's Sword, and slashed towards Arthas.
Facing this world-ending sword, Arthas, arriving later but striking first, unleashed his domain of the undead and met the attack head-on with Frostmourne.
With a resounding "clang," Liu Haotian was pushed back a step, while Arthas retreated three steps!
The point where Hrognir's Sword and Frostmourne collided, due to the shattering of the spatial barrier, created a colossal black hole.
Such a super-massive black hole was capable of devouring an entire star, and even a legendary-level or higher expert nearby would be utterly consumed.
However, in the eyes of Liu Haotian and Arthas, this super-massive black hole was merely insignificant.
It was akin to a normal person casually stepping on a shallow pit, flattening it with a single stomp.
"Rumble!!!!"
As the battle raged on, Liu Haotian and Arthas grew increasingly enraged, and the entire hell convulsed with their fury.
The Styx River, stretching for billions of miles, and the boundless sea of lava, churned with towering waves, altering the very course of mountains and rivers.
When they raged, the heavens and earth raged with them – this was the terrifying might of hell's strongest beings.
"Calamity…"
"Monster…"
"Source of Darkness…"
Among the observers of the ten great races – Human, Elf, Giant, Vampire, Beast, Insect, Dragon, Angel, Mermaid, and Dwarf – those of legendary or higher caliber, witnessing this scene, murmured in unison.
Indeed, apart from words like calamity, monster, and source of darkness, they could no longer find any other terms to describe these two terrifying monstrosities.
Their very existence seemed to be the embodiment of destruction, curses, disaster, and death – natural calamities that left no room for defiance.
Many who had once considered themselves fearless warriors, ready to strike down any who dared challenge their race, now, upon witnessing the destructive power of these two monsters, truly understood what strength, what fear, and what unease truly meant…
Roar! Roar! Roar! Roar…
The two dark-infused monsters battled with increasing ferocity, turning hell into a realm split between pitch blackness and a somber grey.
"Clang!"
Hrognir's Sword and Frostmourne clashed once more, unleashing waves of energy and gale-force winds that churned the surroundings. The majestic heavenly might seemed to overturn the heavens and earth, twisting space and time.
Liu Haotian and Arthas, like monsters, unleashed the terrifying power within their bodies without restraint.
…
Undead energy surged within Arthas, evolving into a sea of death capable of consuming all the world.
Waves of vengeful spirits, stretching for tens of thousands of miles, surged forth, like the world's end descending, ready to engulf all existence.
Sheet after sheet of vengeful spirit waves spread, and wherever they passed, the cries of phantoms and vengeful ghosts echoed, leaving nothing but desolation.
…
Behind Liu Haotian, a dark sun, thousands of miles in size, manifested, straddling heaven and earth.
It appeared as real as the sun itself, exuding an aura of burning everything.
Liu Haotian raised his right hand, and the dark sun behind him flashed, unleashing a torrent of demonic flames that consumed all.
Holding the dark sun, Liu Haotian stood like a titan, a creator god in control of life and death.
In an instant, a cataclysmic roar erupted from the point where the sea of death and the dark sun met…
Liu Haotian roared to the heavens, fully activating his "War God" skill. His black hair fluttered in the wind, and clad in his black, demonic-patterned armor, he was a majestic sight.
Arthas, equally undeterred, his skeletal fire burning fiercely in his skull, took a step forward and unhesitatingly charged towards Liu Haotian.
They were determined to settle the score of victory and life or death today!
…
After a day and a night of battle, Arthas's skeletal body, as grand as a mountain range and obscuring the heavens, was torn to pieces by Liu Haotian.
Liu Haotian, too, was not unscathed.
His demon king true form, several times larger than the mountain range, was covered in countless bloodstains the size of valleys, like a wounded sky weeping blood.
…
Arthas lowered his head, looking at his remaining four arms, and then at his kinsmen still fighting desperately. He asked himself,
"Did I make a mistake this time?"
"No, I did not. This is the only chance for our undead race!"
"The demon race has suppressed us for far too long… Now that we finally have an opportunity, how can I not seize it?"
"Are we going to lose…"
Gazing at the relentlessly powerful Liu Haotian before him, who sought to devour him whole, Arthas's eyes flashed with ruthlessness. He activated his self-detonation mode, intending to take Liu Haotian down with him.
Meanwhile.
Seeing that Arthas had lost his ability to resist, Liu Haotian, with a greedy, gluttonous maw, opened his thousand-mile-wide mouth and lunged forward with all his might, swallowing Arthas whole.
After swallowing Arthas, Liu Haotian stretched his body freely, completely disregarding the lives of the billions of demons and trillions of undead below.
Then, Liu Haotian opened his massive mouth, bared his fangs, and flicked his tongue, as if mocking Arthas's foolishness.
However, in the next second, his joy turned to sorrow.
With a "boom," his voice boomed like thunder, yet it was insufficient to describe the terrifying event. Instantly, centered on the stomach of Liu Haotian's true demon king form, it seemed to collapse, contracting sharply.
The stomach did not collapse on its own; it was merely an illusion created by infinite power converging at a single point.
A contraction, an expansion, and a roar that shook heaven and earth!
"Boom" "Boom" "Boom"
The terrifying roars, like the dawn of creation, instantly stunned everyone. Those who heard them lost their ability to think, watching it all unfold with vacant eyes.
Suddenly, the immense power erupting from Liu Haotian's belly, vaster than the ocean, seemed capable of tearing his entire body apart.
The terrifying explosion annihilated everything. The immense power spread, forming a colossal mushroom cloud that soared into the sky.
In a trance-like state, one could almost see the sky high above parting a gap to allow this terrifying mushroom cloud to ascend.
It was as if it pierced the heavens and the earth, as if it carved up the world, as if it destroyed all existence. Nothing could describe the power unleashed at this moment.
From this mushroom cloud, invisible ripples spread outward, not dense, not clear, yet containing infinite power.
Black, inauspicious blood flowed incessantly from wounds as large as valleys…
From the scale of a small black river, it grew into a small lake, then a great river. Dark energy swirled, and with roars, it eventually became a vast sea of blood…
The boundless sea of blood poured into the depths of hell, and a continuous rain of black blood began to fall from the sky.
"Pain, pain, pain, pain, pain, pain, pain, pain!!!!"
At this very moment, Liu Haotian's mind was wracked with an indescribable, excruciating pain that tore at his sanity, fueling his growing rage.
His eyes, black as night and vast as an abyss, became ferocious and terrifying.
As Liu Haotian's rage intensified, even all of hell seemed to sense the boundless fury of its master, and the surrounding environment suddenly darkened.
"ROAR!!!!!!!!!!!!!"
Liu Haotian raised his mountain-like head and let out a furious roar that echoed throughout the entire crystalline wall world.
The pitch of his cry caused the surrounding lava sea to churn with countless fiery waves, and the Styx River, which had already changed its course, boiled incessantly.
"Rumble!!!"
Even the eternally unchanging, vast sky of hell trembled and shook under the force of Liu Haotian's furious roar.
Tiny fragments of debris, falling from the subtly cracking fissures in the sky, turned into fiery meteors and plunged to the ground.
During this process, Liu Haotian raised his hands and frantically pounded the ground, venting his pain.
The billions of demons and trillions of undead nearby were truly unlucky, suffering countless casualties.
Fortunately, Liu Haotian ultimately endured and survived.
…
He endured. He actually endured. For the power-hungry factions harboring ulterior motives, this was the most terrifying event in existence.
In that instant, all observers, both overt and covert, who were watching this great battle, felt as if time had stopped, their heartbeats slowing by a beat.
