Chapter 274 Immortal Sword Unleashes Fury, Siege on Demon Cave Lord

In contrast, the Zifu-stage demonic cultivators, having secluded themselves in the Demon's Lair Cave for years, failed to recognize the newcomer at first glance.

Of course, this was also related to the significantly enhanced power of the Li Fire Sword of the Returning Abyss (Magic Treasure) after its advancement to the fourth rank.

Fourth-tier immortal swords were exceedingly rare, and advancing their rank was an immensely arduous process. Merely a few months had passed since this sword’s ascension, and the news had yet to reach the demonic cultivators, leaving them momentarily unable to recognize the identity of the newcomer.

"A 100 years ago, when I first saw him, he was merely at the first level of Foundation Establishment, yet he defeated 2 Foundation Establishment cultivators working in tandem, slaying both Zhang (Person Name) and Zuo Zhouqi (Person Name)."

Now, after barely a century had passed, this Eldrin had undergone a profound metamorphosis. Even an ordinary Golden Core cultivator would likely find it difficult to subdue him.

"You seek death? Then go and meet your fate."

Hong Laomo let out a cold sneer and stealthily fled into the distance while no 1 was paying attention.

At this moment, Eldrin merged with his sword, unleashing brilliant azure sword radiance that swept through the battlefield. He stood utterly fearless against 7 or 8 Zifu-stage cultivators.

The Li Fire Sword of the Returning Abyss (Magic Treasure) revealed its keen edge with unstoppable momentum. Wherever it passed, demons and monsters were instantly suppressed, severing 7 or 8 third-tier demonic treasures in succession.

"Insolent."

Witnessing Eldrin unleashing his formidable power, the old demon of the Purple Palace, Late Stage (Cultivation Realm) summoned his life-bound demonic treasure, the Black Blood Canopy, casting it forth to envelop his foe.

Eldrin's gaze turned icy as he recognized the origin of this treasure. The Black Blood Sack was an exceptionally vile demonic artifact.

The method of forging this treasure is excessively cruel. To refine it to the peak of Grade 3, 1 must capture 3,300,000 mortals and inflict them with plague magic, causing them to perish from disease.

They took strands of hair to weave into a demonic artifact, then consecrated it day and night with plague-tainted black blood to complete its forging.

Once refined, the artifact's power proved exceptionally sinister, as it specialized in corrupting spiritual tools and true essence.

Even a cultivator at Foundation Establishment, Late Stage (Cultivation Realm), if caught directly beneath its descent, would find both their true essence and magical treasures corrupted, ultimately dissolving into putrid blood.

Back in the day, the Elder Fiend Hong had also forged this treasure, yet it ultimately met its destruction at the hands of the Old Patriarch’s Li Fire Sword of the Returning Abyss.

At the sight of the Purple Palace, Late Stage old demon still daring to wreak havoc with this treasure, Eldrin swept his sword radiance in a swift arc. With a resounding clang, the Black Blood Shroud was cleaved in 2, while Li Fire surged along the blade’s path, reducing it to ashes in an instant.

"Ah—!" The old demon cried out in agony, spitting a mouthful of blood. "My demonic treasure!"

Seeing the fierce edge of Eldrin’s immortal sword, a group of Violet Mansion old demons began to waver, their thoughts turning to retreat. While driving the Foundation Establishment demonic cultivators to swarm the attack, they sought an opportunity to slip away and save their own lives.

But just then, the group had already cut through the demonic cultivators, and several False Core cultivators closed in on them.

The old clan leader swept a glance over the battle situation and raised his hand to summon the Great White Star Pearls. Within the 7 stellar treasures, the dual energies of Yin and Yang rotated, transforming into Yin-Yang Annihilation Vapor (Cultivation Art) that cascaded downward like a waterfall.

The might of this single strike was already comparable to a False Core cultivator going all out, and it was an area-of-effect divine ability with boundless power.

For a moment, the opposing forces of Yin and Yang annihilated everything in their path. Countless Qi Refining and Foundation Establishment demonic cultivators burst apart as their physical forms exploded, while even the Zifu-stage demonic cultivators were suppressed, forced to devote their full strength to resistance.

Seizing this golden opportunity, Eldrin summoned several immortal swords including the Celestial Separation Twin Blades and the Formless Sword, launching a fierce assault against the powerful foe. In that brief moment, he successively struck down several Zifu-stage demonic cultivators.

Especially the Li Fire Sword of the Returning Abyss (Magic Treasure), truly worthy of being a Pure Yang Immortal Sword, slaughtered those suppressed early and mid-stage Zifu demonic cultivators as effortlessly as cutting through melons and vegetables.

Facing 6 False Core combatants, even a Purple Mansion demonic cultivator could not defy the heavens. The party slew over a dozen Purple Mansion demonic cultivators, sending the demonic forces into complete rout.

Seeing the demonic cultivator fleeing in defeat, the Cave Master of the Demon Abyss’s expression twisted with madness. Yet, true to a Golden Core, Late Stage demonic cultivator, the fiend proved formidable.

Even in the face of such dire circumstances, he refused to flee. Instead, he summoned several demonic artifacts and launched relentless assaults against the crowd, striving to buy more time.

Especially that Blood-Transmuting Demon Blade (Magic Treasure), whose ferocious might dominated the world, actually made it difficult for Lyra (Person Name) and the others to defeat him even when joining forces.

Seeing that they could delay no longer, Eldrin exchanged glances with the several False Core-level combatants and reminded them in a low voice.

"We shall lend our aid, but exercise caution. Intervene from a distance using our magical treasures, and do not rashly approach."

"Very well."

Everyone nodded repeatedly and immediately charged forward to besiege the Lord of the Demonic Abyss.

To ensure victory in this battle, Lyra lent everyone several unused lower-fourth-grade magic treasures.

Elara summoned the Mo Xue Immortal Sword, Xavier unleashed the Qingyang Demon-Repealing Shuttle, Patriarch Fang brought forth the Qiankun Void Wyrm Seal, while Fairy Mujin of the Ziyuan Sect arrived wielding the Golden Sun Incinerating Lantern.

Coupled with Eldrin's Li Fire Sword of the Returning Abyss and the Crimson Sun Void-Immolating Crucible, the Demon Cave Lord found himself momentarily overwhelmed by the relentless assault.

The 2 sides battled for half an hour. Though the Cave Lord of the Demon Abyss repeatedly attempted to slay those pesky False Core cultivators, each of his strikes was thwarted by Lyra (Person Name).

Faced with such a situation, he finally fell into a disadvantageous position. Once a cultivator is at a disadvantage in a magical duel, turning the tables becomes exceedingly difficult—a single misstep could lead to grave injury or even life-threatening peril.

The Lord of the Demonic Cave continued to exchange several dozen more moves with her, but fearing that Lyra (Person Name) would seize an opportunity to unleash the Mirror of the Vast Heaven (Magic Treasure) and strike him dead in 1 blow, he ultimately began to retreat.

He deployed his defensive demonic treasure, the Nether Demon Pagoda, and swept the Blood-Transmuting Demon Blade horizontally to strike the crowd, ultimately tearing open a gap to make his escape.

"Trying to flee?"

In that very instant, Lyra's eyes narrowed sharply as she instantly summoned the Divine Light of the 5 Void Tribulations.

This supreme offensive divine power, unparalleled in might, struck towards the Cave Lord of the Demon Abyss across the boundless void. At this critical juncture of life and death, the Cave Lord of the Demon Abyss desperately raised the Nether Demon Tower, only to have his defensive demon treasure shattered in an instant.

At the critical moment, the fiend evaded the lethal blow, yet his left hand was utterly obliterated into drifting ash by the Divine Light of the 5 Void Tribulations (Cultivation Art).

Though grievously wounded, the Cave Lord of the Demon Abyss, with his formidable power, transformed into a crimson blade aura and shot deep into the demonic cavern.

"What a pity."

"I actually failed to slay this beast."

Lyra's face was somewhat pale as she spoke with a hint of regret.

The Divine Light of the 5 Void Tribulations (Cultivation Art) was a supreme offensive divine ability. With her magical power driving it, it could slay demons and monsters at the Golden Core, Late Stage (Cultivation Realm).

Unfortunately, the environment of the Devil's Cave was peculiar, and coupled with the old fiend's astonishing speed, he barely managed to evade this strike.

"No matter. This fiend has suffered grave injuries, and its strength will diminish by 10 to 20 percent. The battles to come shall be considerably easier."

Eldrin approached and handed her a pill for restoring spiritual power.

After consuming the elixir and recovering some of her mana, Lyra (Person Name) wasted no time, leading the group as they fought their way deep into the Demonic Abyss Cavern.

This time, without any high-level demonic cultivators standing in their way, their progress was remarkably swift. They reached the core of the Demonic Spring in just half a month's effort.

The demonic spring was located within an immeasuraly vast subterranean cavern—a space so expansive it resembled an entire underground world.

As soon as Eldrin (Person Name) entered, he discovered that this subterranean world was profoundly vast, spanning at least several 1000 li in magnitude.

"Hymn—"

Just then, a sword's keen cry echoed from the depths of the Devil's Cave.

Their gazes swept over, only to find that Elder Zhang had already beaten them to it, carving a path through the Demon Cavern's passage.

At this moment, Elder Zhang was single-handedly engaged in a fierce battle against 2 Golden Core demonic cultivators: the Abyssal Cavern Lord and the Venomous Old Fiend.

"Perfect timing."

Seeing reinforcements arriving, Elder Zhang let out a hearty laugh and declared, "Fellow Daoist Jiang, swiftly escort the Mirror of the Vast Heaven (Magic Treasure) to suppress the demonic spring."
