"Disciple of the Underworld King through generations?" The Pain Queen was equally shocked. A figure as mighty as the Underworld King, though dead for millions of years, his legend still echoed across eons and was sung by one generation after another of powerhouses. As Medhi had said earlier, even a remnant disciple from such bloodline would be an extraordinary presence.

If this identity spread out, it would certainly stir up massive ripples throughout the Three Realms. Naturally, the tides would most likely lead to eradication campaigns against disciples of the Underworld King. The three realms' Supreme Beings who had long withdrawn from worldly affairs might even be disturbed. After all, no one wanted another Underworld King or Demon Emperor rising in this world.

"How? You doubt me?" Medhi giggled. "If our master wasn't a descendant through generations of the Underworld King, how could I, a Chaos Supreme Treasure, submit so completely to him? Master, why don't you let her witness what annihilation laws truly are."

"Hmph." Though Leedong was displeased with Medhi's initiative, after scoffing he decided cooperation might be beneficial. If they could subdue the Pain Queen without spilling blood, it wouldn't necessarily be bad either - not only did she possess remarkable strength herself, but as a useful asset she could easily accomplish tasks that the Great Demon King couldn't undertake directly.

At once Leedong unleashed his authentic Divine Annihilation Finger without any alterations. A golden radiance pierced through the air with destructive intent vibrating in every fiber of its being.

"Divine Annihilation Finger!" The Pain Queen's face paled as she screamed, hastily dodging away from that annihilation-laced strike. The fingerbeam crashed into distant walls, boring a bottomless hole effortlessly.

For a moment the Pain Queen regarded Leedong with trepidation. Millions of years ago the Demon Emperor had stirred up terrifying bloodshed across the Three Realms. Fortunately at that time she'd been stationed in the wilderness battling savages and hadn't witnessed first-hand his Divine Annihilation Finger's might. Yet even from her borderlands, she'd heard countless times about this annihilation-based technique until it became a cliché.

Back then dozens of Consolidation Realm experts perished under its blows. Among them was the infamous Blood River Patriarch of the Spirit Beast Realm - having reigned for almost ten thousand years he practiced a variant of the Blood Sutra similar to Demon Clan's techniques. Through this forbidden art he'd nearly reached perfection, capable of manifesting countless copies. As long as one body endured, he would never truly perish.

Though no direct confrontation had ever occurred between him and the Ten Great Masters, if the Blood River Patriarch claimed second place in power, none would dare claim first.

Yet such a formidable existence was pierced through by the Demon Emperor's single finger, his countless copies obliterated. Though annihilation laws inherently countered his technique, it still demonstrated just how terrifying this annihilation-based Divine Annihilation Finger really was - for even the Three Supreme Beings had never mastered these laws.

It was said only four beings had ever grasped annihilation: the Hell God, Underworld King, Demon Emperor, and the Savage Clan's Ancestral Deity. The latter was also exceptionally powerful though due to information suppression most in the Three Realms knew little about him. Even he now faced collapse under the combined might of the three realms' expeditionary forces, his life seemingly reaching its end.

From her perception Leedong's Divine Annihilation Finger still fell short of the Demon Emperor's level but was indeed authentic. Yet she harbored some questions: "Aren't you supposed to be a disciple of the Demon Emperor? Why would an Underworld King descendant be your master?"

"Stupid little demon, that legendary Demon Emperor is actually my master's distant relative through generations. As for Leedong - he's another one of our master's descendants." Medhi boasted loudly, "Though our master hasn't trained long enough yet to reach Supreme level, his potential is limitless! If you submit now, Little Demon Queen, there will be great rewards. Perhaps even help from him to push your cultivation past Consolidation Peak, joining the Ten Great Masters."

"So it's like that," The Pain Queen bellowed with maniacal laughter, "Well since you're an Underworld King descendant, killing you might just grant me his inheritance and this Underworld Banner - what a bargain!"

The sudden shift in her demeanor stunned Medhi: "Little Demon Queen are you crazy? Knowing who our master really is now, do you dare attack?"

"Ahahahaha! If your master were already at Supreme level," the Pain Queen's laugh sent flowers scattering as she licked her lips seductively, eyes gleaming with greedy desire. "Not only would I willingly kneel before him and play his flute - I'd even lick his boots!" Though her words seemed playful, they carried lethal intent: "Unfortunately you admitted yourself he hasn't reached Supreme yet. If he can't beat me how could I possibly submit? Hand over your techniques and this Underworld Banner or else..."

"Brash little demon! Don't you fear me summoning a few Hell Demon Kings to end you?" Medhi roared as her master's life was threatened, "What about my master's Yin Heaven Thunderbolts?"

"Foolish artifact spirit," the Pain Queen sneered. "If you had any Hell Demon Kings ready you would've unleashed them already. As for the Yin Thunderbolts - yes I fear them. But during our conversation here I've layered countless defenses! Though taking a direct hit would still injure me, death won't be guaranteed while your master will definitely perish. Trading my injuries to kill an Underworld King descendant? The math works perfectly." She licked her lips greedily as she stared at Leedong with lustful eyes: "Come here and let the old queen..."

"Hmph." She had miscalculated the state of Leedong's peerless madness. With a cold growl he hurled Yin Thunderbolts directly toward her.

"You're crazy!" The Pain Queen's pupils contracted as she screamed, "You'll die for this!" Though she claimed multiple defense shields would protect her, she now frantically recoiled in panic - only having seventy percent confidence the Yin Thunderbolts wouldn't kill her outright.

The thunderbolts moved deceptively slow yet struck like leeches through space, inexorably pursuing their target. The explosion shattered everything around them into dust. Fortunately this battle had already drifted far from any valuable treasures, sparing those priceless artifacts destruction.

Yet within the blast's core, the Pain Queen fared worse than expected. Her so-called defenses shattered like paper under the shockwave of annihilation.

The explosion was instantaneous - as she claimed she survived, but only by half a body. Below her waist everything had been obliterated in that apocalyptic detonation.

Ten percent of the grand temple crumbled into ruins.

Such was the power of an elite demon king - even with such catastrophic injuries she still roared in fury: "Boy you're dead meat! Even if you don't die from this, I'll flay your skin and bones and stew you for soup!" As her monstrous body began regenerating piece by piece, one could witness the terrifying power of demonic rebirth. Any lost limbs would reform as long as her soul retained enough energy.

Unfortunately she lacked Leedong's absorption abilities to store such reserves within - after recovery her strength had temporarily fallen back to Consolidation Realm novice level.

As she howled threats toward Leedong, suddenly her eyes widened in shock. There he stood emerging from the smoke unscathed, clad in an arrogant black battle armor.

This armor was forged through countless trials with refined Chaos Black Iron - not only could it self-repair but also adapted seamlessly to its wearer's body shape. After all, at certain cultivation levels fighters might grow massive during combat, requiring armor that could scale accordingly without compromising protection.

Though Leedong had been pushed to madness by his peerless state, he retained enough control through years of practice. Before launching the Yin Thunderbolts, how could he be so careless?

He had shrunk his form before donning the self-adaptive Black Emperor Armor and layered additional protection from authentic Demon Emperor techniques - an indestructible Golden Flesh armor. Still unsatisfied, Leedong instantly summoned back the Underworld Banner to wrap around him most intimately. Though Medhi screamed in protest during that instant, could she truly resist his sheer dominance?
