Chapter 421: Imperial‑grade Yin Vein Yin Spring Spirit

In the boundless desert, countless crisscrossing thousand-zhang deep abysses lie; atop those winding, dragon-like abysses stand numerous eerie seven-story bronze ancient towers emitting strange light.

Waves of murderous talisman symbols burst forth, emitting a chilling, bone‑piercing dark sound, as if striking the soul‑requiem of all living beings; countless Huanyu cultivators who came here for treasure feel their scalps go numb.

The Pu Mo Tree Killing Calamity has just ended, yet now Yin‑ming armored soldiers appear to seize lives; many cultivators dare not clash, fleeing in panic to preserve their lives.

Across the boundless desert, severed limbs and broken bodies are everywhere, visibly melting away at a speed discernible to the naked eye.

Those Yin‑ming great armies clad in armor are riddled with countless wounds, as if they have endured countless battles; now, like puppets, they fix their gaze on Huanyu cultivators, follow the scent of vitality, and move to seize the cultivators' lives.

Those bronze ancient towers are downright sinister.

Left and right, batches after batches of eerie vicious soldiers keep pouring out like desert army ants, turning everything they pass into withered bones.

A formidable Huanyu cultivator protected his companions with thunder‑like means, hastily clashing palms with a Yin‑ming vicious soldier; the cultivator was flung backward, his vitality rapidly fading, even his fists turning to pulp.

"This is extremely bad!

"The deathly aura on these soldiers is too thick; we simply cannot defeat them.

"Retreat quickly!"

The Huanyu cultivators were all stunned.

It's gotten this bad—too terrifying.

We merely penetrated the fringe of the Ancient Great Sect's ruins, never entering the central Haotian Palace, yet wave after wave of cultivators have had their lives reaped.

"Hiss!"

The Dadi Ewei Xi smashed through layer upon layer of sand‑waterfalls, encountering the Yin‑ming vicious soldiers; a strange scene unfolded as the thick deathly aura devoured the beast's vigorous life force, and its earth‑spirit armor on the Dadi Ewei Xi collapsed piece by piece.

The protective shield, corrupted by the deathly aura, trembled violently, showing signs of imminent collapse; the cultivators aboard the Dadi Ewei Xi panicked, desperately pouring Spiritual Power into the shield.

Longling gazed at the Yin‑ming armored soldiers, his heart surging with turmoil.

I never imagined these deathly war‑troops could be so terrifying; Huanyu cultivators standing before them cannot resist at all and are crushed outright.

"What do we do!

"There is no solution; we will likewise age and die miserably like the cultivators ahead.

"These soldiers are great omens; they feed on living beings, cannot be eradicated by killing, and only grow more numerous!"

Even Qin Cang's expression changed drastically at this point, and he spoke up.

Heiyao's face showed a tormented expression, until finally he clenched his teeth tightly.

She took out a purple talisman; as Spiritual Power was poured into it, the talisman blazed with purple light, and the winding sigils on it instantly came to life.

Zila‑la…

Ripples of the purple talisman spread terrifying electric patterns in all directions; every cultivator launched their treasures with powerful attacks to assist, causing the front of the Dadi Ewei Xi to clatter loudly as a new path of life was forcibly opened.

Countless Huanyu cultivators' eyes flashed with brilliance; they followed the path opened by everyone, trailing behind the Dadi Ewei Xi, and surged into the desert's depths.

This directly provoked the wrath of the Yin‑ming vicious soldiers; countless of them flashed menacing red in their eyes and surrounded the Dadi Ewei Xi carrying Heiyao and others, nearly making Heiyao and company explode with anger.

Chilianqi's face flushed red, and he almost wanted to stomp his foot.

She looked around; it seemed they had become the core of the Yin‑ming vicious soldiers' encirclement. Although the Three Light Divine Fire can restrain the Yin‑ming vicious soldiers, the soldiers are too many; the terrifying Yin‑ming lethal qi gathered together, reaching ultimate yin and cold, so dense that the power of the Three Light Divine Fire began to wane.

Bang bang bang.

Under a massive infusion of spiritual essence, the purple talisman unleashed divine thunder's wrath, devastating all directions; countless Yin‑ming vicious soldiers turned to dust, leaving only empty armor scattered on the ground.

Those soldiers appear to be fallen disciples of the Ancient Great Sect; their corpses, polluted by lethal qi over countless ages, have become puppets.

They have no consciousness, only a blood‑thirsty instinct.

"What on earth happened to the Ancient Great Sect.

"That it caused countless sect disciples to be burned to ashes, and the lineage collapsed in the river of history."

Heifeng's whole body was shrouded in black mist, emitting an utterly shocking sound.

From the bodies of those Yin‑ming vicious soldiers one can see mysterious Dao patterns intertwining; many of their corpses, having endured endless ages without decaying, remain crystal‑clear like jade, giving an impression of great dignity.

In life they must have been terrifying beings; otherwise they would not emanate the aura of a high‑ranking authority all over.

"Dong dong dong"

Just then, a heaven‑shaking howl rang out, shaking the space.

Everyone saw streams of green mist pouring into those Yin‑ming vicious soldiers, causing their vast inner power to surge out like a flood released from a sluice, pouring forth violently.

The whole world trembled violently; a massive abyss surged forth from the desert's depths, abruptly spreading. Eighteen blobs of green light flickered within the abyss; a Huanyu cultivator who merely glanced at them felt his scalp go numb from the extreme yin lethal qi emanating from those light clusters.

"What the hell is this?

"How can there be such terrifying Yin‑ming power—it could scare someone to death.

"Could it be that after the Ancient Great Sect collapsed, a tomb‑guarding feral beast still survives?"

Qin Cang's wood‑attribute Spiritual Power surged throughout his body, continuously infusing everyone to restore their depleted Spiritual Power.

"That… that seems to be the legendary Yin Spring Spirit."

At this moment, among the traveling companions, the white‑clothed cultivator carrying an ancient coffin exclaimed excitedly.

Upon hearing this, everyone present was startled.

"Did Guinyin Shi missee?

"How could the Universe Cultivation World possibly truly contain such a thing; the Yin Spring Spirit is only said to exist in legend.

"Even in the history of the Universe Cultivation World, tens of thousands of years have passed without any record of the Yin Spring Spirit's trace." Heifeng's scalp tightened in shock as he blurted out in astonishment.

"Yin Spring Spirit—what is this thing.

"Why are you all so afraid of him?" Longling, hearing the crowd's words and seeing everyone act as if facing a great enemy, asked curiously.

"The Yin Spring Spirit is an ultimate supreme evil entity.

"It is said that if it exists in the world, once the Yin Spring Spirit reaches completion, even an immortal descending personally would be powerless against it."

Bibo Xianzi gazed at the endless desert depths, where the eighteen massive light clusters kept rolling; her exquisite face turned deathly pale, and her breathing grew hurried.

"The Yin Spring Spirit is recorded in the Universe Cultivation World's classics, but even if traces can be followed, they are merely a few scattered lines."

"It's also normal that Fellow Daoist Longling hasn't heard of it."

Guinyin Shi bore a massive coffin, gazing at the eighteen gloomy light clusters that resembled eighteen eyes surveying the boundless expanse.

Oh!

Upon hearing that, Longling's face showed a hint of interest.

Heiyao pondered briefly, glanced at the purple sigil floating above the Dadi Ewei Xi's head, and then explained.

The Grand Dao blends together, yin and yang separate, and all things and beings contain the mechanism of the five phases' yin and yang.

The earth has spirit veins, divided into yin and yang veins; these spirit veins were classified by the ancient supreme sovereign of the Huanyu into nine grades and ultimate grades.

Spirit veins are the foundation of all sects; above the nine grades and ultimate grades lies the legendary imperial-grade spirit vein.

The imperial-grade spirit vein aligns with the grand trend of mountains and rivers, secretly harboring the ultimate principle of heaven and earth, the profound mystery of the Grand Dao.

The spirit of the Yin Spring is precisely the legendary supreme imperial-grade spirit vein, a true spirit forged over millions of years, and is the essence of the netherworld.

"It can command all netherworld evil spirits for use; it is said that if it can grow, it can slay immortals and destroy gods." Heiyao gazed into the endless depths of the desert, his tone full of apprehension.

"What Fellow Daoist Heiyao said is correct."

That Yin Spring spirit possesses heaven‑destroying, earth‑annihilating means, and is also the supreme treasure for cultivators of yin evil.

The Yin Spring spirit is a true spirit formed from the legendary imperial‑grade yin vein; its primal netherworld power not only increases the cultivation speed of yin‑evil practitioners.

When facing enemies, it can continually replenish spiritual power, allowing one to innately occupy an invincible position.

Guinyin Shi's face showed regret as he spoke.

It is obvious that the Yin Spring spirit hidden deep in the desert has already become a formidable force; it is certainly beyond his current realm to conquer.

No wonder so many terrifying netherworld yin soldiers appear in the desert; it turns out a legendary imperial‑grade yin vein lies hidden deep in the desert.

That imperial‑grade yin vein even gave birth to the Yin Spring spirit, explaining everything.

Imperial‑grade yin veins are legendary; if placed in the Huanyu Cultivation World, they would be fought over even at the cost of broken heads and bloodshed, and even the hidden ancient and primordial vast forces would be moved to emerge and seize them by force.

Longling listened to everyone's words and pondered in his heart.

Earth cultivators refine the Myriad Soul Banner; if they could obtain the aid of the Yin Spring spirit in this boundless desert, the spirit's primal netherworld power would surely be a potent nourishment for the soul puppets within the banner, enabling them to quickly develop consciousness.

"Quick look, that Yin Spring spirit seems to have been staring at us all along."

Just then, Heifeng discovered that the eighteen mysterious light clusters deep in the desert were changing; those light clusters actually swayed incessantly as the Dadi Ewei Xi shifted its position while charging through the desert.

The eighteen light clusters resembled eighteen gloomy eyes staring at their every move, continuously swaying.

"Heifeng, don't talk nonsense."

"It would scare someone to death!" Upon hearing that, Guinyin Shi involuntarily shuddered, beads of sweat the size of a fist formed on his forehead, and he felt both legs begin to tremble.

"Everyone, don't rush."

The Yin Spring spirit should be sealed by some kind of restriction.

Otherwise, how could it possibly stay so quietly in the depths of the desert, gazing at us, given its legendary heaven‑shaking might? Longling heard this, his face showing a calm, carefree expression, and he spoke.

Everyone thought that made sense.

Observing the aura emanating from the Yin Spring spirit, even without achieving it, one could contend against a sect leader‑level mighty expert of the Supreme Great Teaching; such a terrifying existence would hardly allow a swarm of ants to crawl wildly before it.

Bang.

Just then, a heaven‑shaking, earth‑moving sound arose, and the entire boundless desert shook violently once more.

As the Dadi Ewei Xi ventured deeper into the desert, the people saw a supreme netherworld fiendish soldier burst forth from the desert, stepping on a sword and flying toward them.

The ancient bronze long sword was covered in runes, with supreme array patterns forged into it, emitting a fierce cold light that tore through the Huanyu's might, shocking the heart.

The cultivators on the Dadi Ewei Xi began to feel uneasy.

This netherworld fiendish soldier must be a dreadful sword cultivator, his body entwined with sword intent; even after myriad ages, three thousand sword spirits still swirl around him, giving him an aura of invincibility under heaven and earth; his emergence now is like an unsheathed sharp blade ready to overturn the eight directions and cleanse the world.

Whoosh.

The netherworld sword cultivator landed in the void; his sword intent spread like a spark becoming a prairie fire, and a rain of swords fell like a torrential downpour, instantly causing countless casualties among the cultivators who entered this place.

Countless Huanyu cultivators began to flee in disarray; that sword cultivator's overwhelming strength was simply unstoppable, and none dared to oppose him.

Between heaven and earth, the sword intent's prairie fire stirred the winds in all directions; winds rose, clouds surged, angry sand rolled, and the surrounding yin winds gusted, as if heralding an apocalyptic calamity.

"Pfft."

The Dadi Ewei Xi swiftly dodged the violent sword intent, while the Huanyu cultivators following behind had no time to evade; they instantly blew apart, turning to smoke and dissipating in heaven and earth, causing a thick blood‑red mist to spread in all directions, making the fortunate surviving Huanyu cultivators curse behind them.

"Damn thing is too awful."

"When dodging, they didn't even give a warning, nearly getting us killed."

Some Huanyu cultivators were furious.

She steadied her stance, turned around and ran; without the Dadi Ewei Xi clearing the way, she dared not venture deeper into the desert's interior.

That netherworld sword cultivator, with a single sword, opened the heavens; his supreme sword intent slaughtered in all directions, his invincible might vast; even a sect leader‑level mighty expert would be bloodied, and they are nothing—if they tried to fight their way through, death would be certain.

They lack the mysterious divine beast that the Dadi Ewei Xi possesses, which can roam freely within restrictions and look down on all directions.

"Hurry up!"

Heiyao's face was extremely tense, frantically controlling the purple sigil atop the Dadi Ewei Xi's head to counter the netherworld sword cultivator.

The destructive surge charged the ox palace, the Dadi Ewei Xi's earth‑yellow light blazed to the extreme, breaking through the layers of shackles ahead, and it fled at extreme speed.

"No."

"We can't keep up with the Dadi Ewei Xi's speed; hurry and flee!"

The surviving Huanyu cultivators behind the Dadi Ewei Xi saw the distance to Longling and the others widening, their faces turned pale, and they scattered in all directions, fleeing.

The netherworld sword cultivator is too strong; without Longling's party clearing the way ahead in the desert, even if they united and pressed forward, death would be certain.

The vast desert saw the scattered fleeing cultivators also meet disaster, being surrounded and intercepted by the mysterious netherworld fiendish soldiers; many cultivators unable to replenish their spiritual power, exhausted, were encircled by the netherworld fiendish soldiers and devoured clean.

Huanyu cultivators gazed at the scattered remnants of clothing and bloody crimson stains on the desert, all terrified out of their wits.

Some who hesitated about whether to make one last charge into the desert immediately decided to retreat without looking back.

「It's no good.

That Netherworld Sword Cultivator kept staring.

If we don't stop it, once the power of the purple talisman is completely exhausted, everyone will be in mortal danger. »

Heiyao watched as the ancient sword in the Netherworld Sword Cultivator's hand rang out, and he could no longer suppress the fear in his heart.

That Netherworld Sword Cultivator gave her a sense of deadly threat; even though he possessed myriad methods, facing that Netherworld Sword Cultivator now made him feel utterly powerless.

Bang bang bang.

Three thousand sword spirits, carrying netherworld killing aura, fell upon the protective light shield of the Dadi Ewei Xi, unleashing thunderous explosions; even Qin Cang turned deathly pale, the great formation controlling spiritual power shook violently, his body trembled violently, and he had reached the limit of supplying everyone's recovery of spiritual power.

«Everyone, whatever methods you have, don't hide them. »

«Now we are cultivators on the same boat; if the boat capsizes, we all die. »

Qin Cang said with a deathly pale face.

That Netherworld Sword Cultivator possesses a supreme might of 'if not me, who?'; the desert's power aids him; the killing intent is endless; these cultivators simply cannot withstand it.

Once spiritual power is completely exhausted, they will surely be swarmed by the Netherworld fiendish troops; at that moment there will be no way to heaven or earth.

«Let this seat give it a try! »

At that moment, Longling stepped out from the cultivators maintaining the defensive formation and said, his icy eyes flashing with a fierce light.
