The moment the blood mist was touched by the Annihilation attribute, it utterly perished. This was precisely why the Blood Boy Demon looked so utterly panicked upon witnessing the Finger of Immortal Slaying. Back then, the Blood River Ancestor, whose cultivation was heaven-defying, could not withstand the Law of Annihilation for even a moment. This speaks volumes about the terror of the Annihilation Law.

Of course, Lei Dong knew virtually nothing about the Law of Annihilation. The sliver of Annihilation Law contained within the Finger of Immortal Slaying was transmitted to Lei Dong by the Demon Emperor through a peculiar form of inheritance, much like how many monstrous beasts inherit techniques and wondrous arts through their bloodlines. It became an instinctive technique—Lei Dong could execute it as if by instinct, without truly grasping its nature, similar to how he once utilized the Spatial Law found in the Asura Wings.

Naturally, the power displayed could not compare to that of the Demon Emperor in his prime; it was less than one-hundredth of the original might. However, the Blood Boy Demon before him was currently only a Nascent Soul stage avatar.

In the very instant the blood mist that formed the Blood Boy Demon was annihilated, in some distant, unknown space, a terrifying, scarlet river of blood, stretching across the heavens and reeking of unbearable stench, suddenly let out a roar of agony for no discernible reason. The already surging river thrashed violently, and countless waves hundreds of feet high condensed into a vague human face, bellowing furiously, "Who, who annihilated this venerable one's avatar?" Throughout the sky, lightning flashed and thunder roared, the crisscrossing bolts of electricity bearing a distinct crimson hue.

After three such roars, the Blood Boy Demon seemed to be in extreme rage and pain. To vent his fury, he summoned vast, bloody waves across the heavens.

Within the blood sea, countless recorded blood-colored demonic beasts and blood spirits were utterly terrified. Yet, held captive by the Blood Boy Demon's terrifying majesty, they dared not even flee. One by one, they prostrated themselves on the river's surface, only to be shredded and swallowed by the surging waves, paying with their lives for the wrath of the Blood Boy Demon’s true form.

Life, at times, is so fragile and cheap. Without strength, one possesses neither dignity nor even the right to struggle on. Life and death rest entirely upon the mere whim of the powerful.

Setting aside the turmoil wreaked by the Blood Boy Demon's true form, let us turn to Lei Dong. After effortlessly eliminating the Blood Boy Demon, one object remained un-annihilated within the dissolving remnants of the blood mist. It was a blood-colored, semi-transparent bead, no larger than a fingernail. As Lei Dong pondered what this object might be, Xie Feng let out a whoop of delight: "It's a Blood Spirit Orb! This avatar of the Blood Boy Demon actually managed to bring a Blood Spirit Orb down to the lower realm. No wonder, no wonder he could conjure so many Blood Puppets instantly. Lei Dong, quickly secure it." After all, the creature originated from an ancient lineage, meaning such arcane secrets and forgotten histories were within Xie Feng’s purview.

However, this was hardly the time to investigate the orb's properties. Lei Dong casually extended a claw, manifesting a shadowy appendage several yards long, capturing the object named the Blood Spirit Orb and tucking it into his storage ring. His expression immediately turned unfriendly as he fixed his gaze upon the Crimson Refining Divine Serpent. The Crimson Refining Divine Serpent possessed formidable divine abilities, and even fighting two Nascent Soul level puppets simultaneously, it still held the upper hand, driving both avatars into a continuous retreat with no means of striking back.

Yet, the Seductive Serpent showed no trace of excitement. Having just witnessed the shocking scene of the Blood Boy Demon being instantly killed in a single move, she, in her true serpentine form, was utterly dismayed. Though she never expected this avatar to return alive from the mission, how it died was a matter of considerable importance.

If the mission were completed and she self-terminated to return, she could bring back the majority of her spirit and all her memories, thereby minimizing the loss to her true body. Furthermore, her Master would bestow considerable rewards, more than enough to cover the losses and even yield great benefits.

But if she were utterly destroyed here, soul and spirit annihilated, it would be disastrous. Not only would her true form suffer immense damage from zero spirit retention, but she would have absolutely no knowledge of what transpired after descending to the lower realm. Most critically, she would face punishment from her Master—the consequences of which were enough to send a chill down her spine just contemplating them.

After seizing the Blood Spirit Orb, Lei Dong shifted his malevolent gaze toward the Seductive Serpent, causing her to feel a chilling sensation for the first time since descending. She hastily transformed from a giant serpent hundreds of yards long back into the form of a stunning young woman. Utilizing movement techniques, she entangled herself fiercely with the two puppets, panting lightly as she called out remotely to Lei Dong, "Little Brother, I know you have no ties to this Netherworld Hall. Why not stand aside? If you would grant me this great favor, I, Seductive Serpent, am willing to offer generous gifts that will surely satisfy you—even if you demand I pledge myself to you, it would be no issue."

"Hmph! Shameless, slutty snake," Xie Feng spat out in a sudden surge of shame and anger upon hearing the Serpent shamelessly attempting to seduce Lei Dong.

Unexpectedly, Lei Dong showed no reaction whatsoever. Instead, he quickly formed a hand seal, reining in his scattered Ghost Soldiers. The surviving ten thousand suicidal ghosts rearranged themselves into a battle formation, and the Belly Cannon Ghosts, having exhausted their Nether Qi, had seemingly recharged in the interim. One by one, they bared their ferocious fangs and aimed them at the Seductive Serpent, as Lei Dong calmly transmitted a message to Xie Feng: "Senior Xie Feng, if your condition is stable, let us eliminate this Crimson Refining Divine Serpent first."

Hearing Lei Dong’s mental resonance, Xie Feng felt as if she had heard an immortal's melody; she had long disliked this Crimson Refining Divine Serpent. Immediately, she unleashed Phoenix Dance of the Nine Heavens, her tail plumes—intermingled with Xie Feng's resentment—slashing fiercely toward the Seductive Serpent. In addition, the slightly recovered Dark Serpent also began to snarl, its hatred for the Seductive Serpent now bone-deep, and joined the fray.

Even in her true form, the Seductive Serpent could only barely fend off two puppets. How could she possibly fight against the combined assault of four Nascent Soul stage entities? Lei Dong’s cold indifference provoked her vicious nature. She immediately reverted to her colossal Crimson Refining Serpent form, whipping her tail in mid-air, seemingly leaping out of space directly before Lei Dong. Coiled, she struck swiftly, intending to swallow Lei Dong whole in one gulp.

Facing this giant serpent hundreds of yards long, Lei Dong, in his human height, wouldn't even qualify as a piece of grit between her teeth. Even more terrifying was that her method of devouring was no simple attack; it contained sinister and immense divine powers. Setting aside the spatial law woven into her strike that made evasion impossible, she could also pre-solidify the space around her prey, preventing instant translocation.

Having anticipated that the infuriated Seductive Serpent might target him, Lei Dong remained utterly composed.

Swish, swish—two Profound Yin Fingers shot forth, their pale, ghostly light streaking toward the serpent's maw like meteors. The Seductive Serpent, having just witnessed the slaughter of the Blood Boy Demon, who was demonstrably a cut above her in strength, turned pale with fright. She dared not swallow him now and frantically dodged left and right.

Little did she know that Lei Dong's previous two strikes were merely feints. Lei Dong’s Finger of Immortal Slaying was developed from the foundation of the Profound Yin Finger; the two shared a ninety percent visual similarity. However, the true essence consumed by each technique was vastly different. Given his current cultivation, unleashing the Finger of Immortal Slaying was already a stretch. The strike that killed the Blood Boy Demon was his absolute limit, having already drained a massive amount of his true essence, making it impossible to unleash two more fingers in rapid succession.

Alas, the Seductive Serpent was completely unaware of this. Deceived by Lei Dong’s calm exterior, she missed the optimal opportunity to slay him. Taking advantage of her evasive maneuvers, Lei Dong executed Ghost Shadow Evasion, retreating at extreme speed.

"Vile woman, how dare you!" Xie Feng cried out in alarm, having nearly been ambushed by the Seductive Serpent’s surprise attack due to her momentary carelessness. She shrieked in fury, spreading her wings and flashing forward, extending her sharp talons like a fierce raptor, aiming directly for the serpent’s head. If that blow had landed solidly, the Crimson Refining Divine Serpent would have been maimed, if not killed outright.

But the Seductive Serpent was no pushover. Seeing that she could no longer kill Lei Dong, she retracted her head, re-coiling into a defensive circle, then lunged at Xie Feng with lightning speed, snapping her jaws. The phoenix and the serpent immediately engaged in a life-or-death battle in mid-air. However, the Seductive Serpent’s true body was a Integration stage existence, possessing exceptionally rich combat experience and awareness. Within mere moments, Xie Feng fell into a disadvantage.

Yet, Xie Feng was not fighting alone. The two puppets and the Dark Serpent surged forward, unleashing various techniques upon the Seductive Serpent in turns. No matter how formidable the Seductive Serpent was, her current combat strength was only at the Nascent Soul level. Faced with such an overwhelming force, numbering several times her own, she soon found herself struggling. Her massive serpentine body quickly accumulated wounds, and despite several attempts to break through, she was forcefully driven back.

The Ancient War Giant managed to force back the two puppets with a single move, intending to rescue the Seductive Serpent, but it was blasted back by a continuous barrage of Nether Fire cannonballs fired by Lei Dong, who waited nearby. Even for a powerful entity like the Ancient Giant, with its current mere Nascent Soul strength, it could not ignore the massive artillery fire. It was subsequently entangled by the two puppets.

The Seductive Serpent, seeing her breakthrough hopes dashed and her injuries worsening under the siege of the four Nascent Soul entities, realized that unless something changed, she would likely be ground to death by these lower-realm powerhouses. Being highly intelligent, she discerned that the Infant Soul boy seemed to be the hidden leader among these Nascent Soul cultivators. Out of options, she spoke again, begging, "Little Brother, I, Seductive Serpent, am willing to become your maid from this day forward, loyal without question. I only beg you to spare me this once." Her words flowed with undulating power, causing a profound disorientation in the listener, clearly employing some kind of charm spell.

But the answer she received was a coordinated barrage from Lei Dong’s Belly Cannon Ghosts. Lei Dong was hardly a fool; there was no way he would blindly trust the words of this Crimson Refining Divine Serpent. She was merely an avatar; even its loss would not jeopardize her true form's life. How could an Integration stage powerhouse deign to offer service to a human Nascent Soul cultivator for the sake of losing an avatar?

As for the charm technique, Lei Dong didn't know why, but his resistance to such arts was exceedingly strong. Furthermore, the Seductive Serpent did not specialize in charm magic; how could she possibly affect Lei Dong? By this time, Lei Dong had already activated the Grand Nether Art; the sky was filled with drifting black mist, and he himself was utilizing Ghost Shadow Evasion, virtually merging with the Nether Qi. Now that the battle was decided, all that remained was to slowly grind her down to death.
