The core of an Undying Undead was the Soul Flame.
If the Soul Flame was extracted, no matter how powerful the undead was, it would fall, utterly becoming a cold corpse. Often, even if an undead's body was destroyed, as long as the Soul Flame remained, it could rely on its undying traits to rapidly regenerate and rejoin the battlefield.
Though it appeared that large swaths of undead were being slaughtered, in truth, only around half of them were truly perishing.
But now, after Yi Tianxing's intervention—even those undead lying on the ground, not yet dead, lost their Soul Flames. Once extracted, they became lifeless corpses. Upon being devoured and refined, they naturally perished.
In a single harvest, 729 Soul Flames were seized—meaning more than seven hundred undead had truly fallen.
This was a massacre, like reaping wheat.
The Yin-Yang Rings flew out, extracted the Soul Flames, then returned, and flew out again. The whole cycle took no more than a few breaths.
Soul Flames were being harvested in massive batches. Each breath brought an indescribable pleasure.
One could clearly feel that above the Innate Yin-Yang Divine Diagram, several source entities formed by Yin-Yang divine abilities began to emit brilliant spiritual light, with divine rhythm flowing endlessly. They were becoming stronger in the process.
Waves of Yin-Yang essence settled into the Divine Diagram.
Refining the Soul Flames produced Soul Essence, which was divided into three parts. Roughly 30% was absorbed by the Innate Yin-Yang Divine Diagram as nourishment for its growth. Another 30% was stored within the diagram. The remaining 40% was distributed across various Yin-Yang Divine Diagrams, tempering their source and enhancing their spiritual nature.
These three parts served three functions:
Strengthening the Yin-Yang space—the very foundation of the Yin-Yang Life Orifice.
Storing essence—to nurture new Life Orifice divine abilities.
Tempering existing divine abilities, enhancing their power and quality, allowing them to evolve and become protective forces of the Dao.
This was the very instinct of a Life Orifice.
"Such a domineering divine ability—it's as if it was born to counter undead," Jiang Ni muttered, eyes sharp.
Even broken into individual Yin-Yang Rings, this technique remained formidable, suppressing all undead beneath the Life Orifice realm, and even those within it. One ring might not suffice, but two or three could. It was a divine ability made for hunting souls, akin to the legendary Soul-Hooking Chains of netherworld envoys.
And most crucially—it exuded a natural innate spiritual charm.
"So powerful... So this is what a true expert looks like." Song Yuting was shaken as she gazed at Yi Tianxing.
She realized that even while standing still, he could slaughter undead as easily as mowing grass. His image burned itself into her heart with a sense of awe—and even an instinctual realization: this was not someone she could ever afford to become enemies with.
"Those strange rings can actually extract Soul Flames. Once taken, the undead die for real—no resurrection. This divine ability naturally counters the Undying lineage. As long as he's alive, he's a terrifying threat to all undead," thought the high priest of the undead, who had taken notice of Yi Tianxing's actions despite the arrow rain and chaos.
A flicker of murderous intent was born in the priest's heart.
Someone like this must be killed.
However, with the Wind-Flower-Snow-Moon Formation still intact, even the undead army couldn't cross the barrier. They could only bombard the formation with attacks and divine spells.
Though many undead fell, the formation's light visibly dimmed—maintaining it was consuming tremendous energy.
It wouldn't last much longer.
Thus, the current goal was to use the formation to slaughter as many undead as possible—and Yi Tianxing wouldn't waste such an opportunity.
Every second counted.
Clang! Clang! Clang!
The Yin-Yang Rings shot out again and again, bringing back armfuls of Soul Flames. Corpses piled up visibly all around.
Whoosh!
From Yi Tianxing's body, a stream of invisible light burrowed underground—instantly appearing outside the formation, deep in the battlefield.
It was the Hongmeng Heavenly Emperor Tower.
Without hesitation, it unleashed a powerful devouring force, rapidly absorbing the corpses of completely dead undead.
These undead, while their core was the Soul Flame, had bodies tempered by it, making their physical forms even sturdier—comparable to metal. Excellent materials for refining bone crystals, bone arrows, or simply raw energy to feed the Hongmeng Tower.
Yi Tianxing chose the latter: refine them into Chaos Qi to strengthen the tower.
As the tower absorbed the corpses, they disappeared silently, as if a massive invisible mouth was devouring them from below.
"Something's devouring the bodies," Jiang Ni noticed immediately, though he couldn't say what exactly was happening. But something was clearly at work underground.
Clang! Clang! Clang!
The Yin-Yang Rings continued suppressing and harvesting Soul Flames. The number had surpassed hundreds, thousands—even tens of thousands.
Thanks to the Wind-Flower-Snow-Moon Formation, the number of undead deaths was staggering. Many had nothing left but their Soul Flames, making the rings' job easier. Sometimes, a single ring could trap two Soul Flames at once.
With tens of thousands of flames refined—
The Innate Yin-Yang Divine Diagram swirled with black and white divine light, interweaving in miraculous transformations.
Its three Yin-Yang divine abilities were bathed in thick spiritual radiance, overflowing with Daoist laws.
Whoosh!
A flash of divine light, and the stored Soul Essence began to evolve under the influence of Yin-Yang laws.
It was a profound and natural transformation.
Countless runes danced, countless laws flowed—
Until they all merged, forming a new divine source that coalesced into a bizarre treasure vase—red and blue, split into yin and yang halves.
The vase was jade-like, glowing softly, pleasing to the eye like a flawless work of art.
Look closely, and one could see mysterious rays flickering from its mouth—mystical and terrifying in its depth.
Life Orifice Divine Ability – Yin-Yang Treasure Vase!!
The moment this divine ability was born, its complete knowledge rushed into Yi Tianxing's mind.
It was a supreme ability named Yin-Yang Treasure Vase. Though born as a Yellow-tier divine ability, it quickly absorbed the remaining Soul Essence and—relying on the deep foundation of the Yin-Yang Life Orifice—evolved into a Profound-tier divine ability.
✨ Yin-Yang Treasure Vase:
A treasure birthed by Yin and Yang Qi. Within it lies the Seven Treasures, Eight Trigrams, and Twenty-Four Qi.It can trap living beings. If one remains silent, the interior is cool and still. But if they speak—fire ignites, and within a short time, the target is refined into nothingness.The vase then condenses a Yin-Yang Treasure Pill.
This pill is not an ordinary elixir. It is created by refining every aspect of the captured being—flesh, soul, essence. There are nine grades, with one-turn as the lowest, and nine-turn as the highest.
These pills can:
Boost cultivation, infuse Yin-Yang Qi, temper the body, and advance one's body refinement path.
Heal even those on death's door, preserving life at the brink.
At nine-turn, they can revive the dead, regrow flesh from bone, even restore a wandering ghost to full life—truly priceless treasures.
Such a divine ability was heaven-defying in its power.
Provided, of course, that one could capture and refine powerful beings—otherwise, it remained only potential.
But its very nature was utterly extraordinary.
