In an instant, Lei Dong plunged into the familiar Unrivaled state. Those demonic eyes, already brimming with irrational savagery, now appeared even more cold and infused with a savage aura. His muscles, already explosive, seemed to swell suddenly, every single fiber brimming with boundless power.

A stomp of his foot shattered the incredibly solid ground of the Crystal Ancient Clan, and like a demonic bomb cloaked in explosive air currents, he lunged towards the Queen of Pain, completely ignoring the myriad layers of whip shadows swirling around.

Crack-crack~ The Whips of Pain struck the enlarged demonic body like a relentless rain, sending ripples across its surface. The true power of the Whips of Pain lay not in their raw impact, but in the fundamental laws woven within them, capable of tormenting the body and soul, inducing extreme agony and intense desire.

However, Lei Dong's Unrivaled state plunged him into a near-uncontrollable surge of power, rendering him immune to any damage, pain, or other emotion. The only thing remaining was the instinct for attack and slaughter. The sensation of the Whips of Pain striking him was utterly erased by his berserk will; he felt practically nothing.

"How is this possible?" The Queen of Pain’s expression shifted. She hadn't expected the enemy to figure out how to nullify her Whips of Pain so quickly. Furthermore, under that savage secret art, the power erupting from the Demon King was terrifyingly immense.

Leveraging his profound mastery and acute sensitivity to the Laws of Space, Lei Dong flickered, darting directly through spatial fissures, displaying an agility ill-suited to his current massive form. He flashed before the Queen of Pain and brought his monstrous Demonic Greatsword down with overwhelming force.

Since the Whips of Pain had proven useless, the Queen of Pain, with a drastic change in expression, hastily swapped for a uniquely shaped demon sword and rushed forward to parry.

Boom~ The body of the Great Strength Demon King was fundamentally renowned for its might, and the Great Strength Demonic Art he practiced was etched into his very life-factor sequence, like a brand upon his essence. By absorbing the Great Strength Demon King’s life-factor sequence, Lei Dong was essentially indistinguishable from that Demon King at that time.

The reason was simple: as the Great Strength Demon King continually cultivated and advanced his realm, his life-factors were also constantly evolving and growing. Consequently, at intervals, the newest life-factor sequence within his soul would be replaced by the latest version.

A high-ranking Demon Clan member inherits only a unique life-factor sequence from their parents at birth; during their growth, these life-factors continuously change.

This was contrary to the misunderstanding that Lei Dong had merely acquired the life-factors of a high-ranking Demon Clan member.

To be precise, he had obtained the Great Strength Demon King’s essence when he was at the initial stage of integration and had cultivated the Great Strength Demonic Art to the Great Accomplishment stage.

Thus, when Lei Dong consumed and transformed using the Great Strength Demon King’s life-factor sequence, he inherited everything within those factors. For instance, the immensely powerful demonic body resulting from practicing the Great Strength Demonic Art. Furthermore, if Lei Dong wished, he could continue to refine the Demonic Art, continually tempering this demonic body and altering his life-factor sequence further.

However, the Demonic Art practiced by the Queen of Pain was not one famed for sheer power. She actually practiced a canonical Demon Clan technique called the Heavenly Demon Art, which, when mastered, allowed one to become the Demon of Demons. The Heavenly Demon Art was formidable, but generally balanced; although it offered a significant boost to power, it simply couldn't compete with the raw strength granted by the Great Strength Demonic Art.

Incidentally, the Heavenly Demon Mu Yanmei practiced the Great Heavenly Demon Method, which was the genuine, high-ranking Demon Clan technique—however, it was not the original version practiced by the Queen of Pain. It was an evolved cultivation method, refined over hundreds of millions of years by mighty beings among humans, making it more suitable for the human physique.

Otherwise, given the vast difference between human and high-ranking Demon Clan physiologies, humans attempting to cultivate the original Heavenly Demon Art would face an extremely high probability of death or qi deviation.

Although the Queen of Pain was already at the mid-stage of integration, in terms of pure strength, she was slightly inferior to the rampaging Lei Dong. Her hasty block sent her slender, graceful body flying backward. With a muffled groan, a trace of blood appeared at the corner of her mouth; she was clearly injured by the tremendous force.

Lei Dong, showing no mercy, pressed his advantage and brought the Demonic Greatsword down again.

Yet, while the Heavenly Demon Art was not focused on brute force, it was still a supremely potent and orthodox demonic art. Its true strength lay in fostering comprehensive balance in the demonic body, and in terms of recovery, it was unparalleled among all demonic arts.

Faced with Lei Dong's relentless assault and her own injury, the Queen of Pain was thoroughly provoked and ignited. Rich demonic energy erupted around her, and with a roar akin to a fierce beast, she shrieked, "Did you really think I was raised on stale bread?" She seized her greatsword and countered his attack.

Clang, clang, clang~ The two Demon Kings exchanged dozens of blows in mere breaths. With the Heavenly Demon Qi ignited, the Queen of Pain's overall power increased, and in terms of pure agility, she even surpassed Lei Dong.

The astonishing destructive power unleashed by Demon Kings in the integration stage was more than the meticulously crafted Sacred Temple of the Crystal Ancient Clan could withstand; corridors, murals, secret chambers—all exploded under their furious back-and-forth struggle. A woman driven to ferocity is terrifying, but a female Demon King driven to fury is a truly dreadful spectacle. Lei Dong, relying on his demonic body and the Unrivaled state, was being pressed back and beaten by her.

It was only thanks to Lei Dong's ingrained command over the Laws of Space that he could barely sustain the continuous skirmish through the potent Spatial Ghost Shadow Evasion technique. Under normal circumstances, the Unrivaled state was unsustainable for long periods. However, his demonic body was inherently brimming with immense power for him to expend. Moreover, having just devoured the Bloodthirsty Demon King, Pussius, and converted his integration-level nascent spirit into pure Chaos Spiritual Qi, these energies were stored in his demonic body's sea of qi, ready for immediate deployment.

Because of this, Lei Dong, though fighting clumsily, could persist. Furthermore, in his Unrivaled state, he feared nothing; every strike and maneuver was executed as if staking his very life. The Queen of Pain, clearly uninterested in a mutual annihilation, fought cautiously.

"Master, you are so mighty. Keep going, kill that she-demon, and then toy with her body and ravage her soul." Ming Ji, restless within Lei Dong’s soul, began to incite him again, spitting out a stream of lewd words.

She failed to realize that Lei Dong was currently trapped in the savage frenzy of the Unrivaled state, not his usual rational self. In this condition, any means were permissible as long as they led to the enemy’s demise. Hearing Ming Ji’s words, the berserk Lei Dong vaguely remembered that he possessed such a Chaos Supreme Treasure.

Without hesitation, he commanded it mentally. The Hades Banner obediently spiraled out from his soul, growing rapidly against the wind until it became a formidable, inky-black banner radiating imposing authority.

"No, Master!" Ming Ji shrieked. "This servant is merely an auxiliary spiritual treasure; without a Ghost Army formed, I have no combat capability whatsoever."

"No combat capability? Then what use are you?" Lei Dong transmitted his frustration and anger via mental waves. "If that's the case, go self-destruct and take her with you."

Ming Ji was stunned. She had always held herself in high regard. Though she feigned obedience out of fear of being devoured by Lei Dong, she was deeply proud at her core. She certainly had grounds for pride; among all Chaos Spiritual Treasures in the Three Realms, the Hades Banner ranked at least in the top ten, and this ranking would soar once she accumulated enough integration-level souls.

Therefore, she was certain of her value, believing that no matter who obtained her, they would treat her as a priceless treasure, let alone use her to self-destruct. Using the Hades Banner to explode against an enemy was an utterly insane notion—as foolish as Lei Dong, in a previous life's fight, taking a priceless, limited-edition antique and throwing it to smash someone's head.

Unfortunately, Lei Dong was currently in the flawed Unrivaled state; logic was useless against him. Through his mind-link, continuous commands ordering her to self-destruct flooded her awareness.

Had she not been soul-refined by Lei Dong, Ming Ji would have simply ignored such orders. But now, she had been refined by his soul, and recently, the refinement process had deepened considerably. Both the artifact spirit, Ming Ji, and the Hades Banner itself were bound to absolute obedience to the Master’s commands.

This left Ming Ji in agony. The aura within the Hades Banner became violently chaotic, ancient and mysterious formations spun wildly, and in the blink of an eye, it neared the brink of detonation.

"Oh, no, Master, please, don't self-destruct! This servant submits, I won't dare again! You can ask me to play the flute, and I will..." The immense tearing force caused Ming Ji to cry out in terror and pain. "Wait, Master, you have a Grand Yin Heavenly Thunder! That's what you use for blowing things up! This servant is an auxiliary treasure, not a damn atomic bomb, boo-hoo..." The poor Ming Ji finally experienced what true madness and power felt like, suffering terrible abuse.

Fortunately, Ming Ji's final reminder did indeed make the frenzied Lei Dong recall the existence of that item, a treasure seized from Pussius.

Immediately, he stopped forcing the Hades Banner toward self-destruction. He endured a sword strike from the Queen of Pain, allowing his arm to be severed, and then retrieved the Grand Yin Heavenly Thunder.

"Grand Yin Heavenly Thunder? Holy crap, no way!" The Queen of Pain, having lived for nearly ten million years, was widely experienced; few things in the Three Realms could escape her notice. When the Grand Yin Heavenly Thunder appeared in Lei Dong's hand, she froze. The dense Grand Yin energy allowed her to instantly recognize the object.
