Chapter 353: The True Two Yin-Yang Sword Qi!!

The massive fist imprint carved into the black rock wall seemed merely the result of pure force unleashed—simple and brutal.

But when Chen Mu, in his state of "Five Qi Converging at the Source," with exquisitely acute spiritual perception, carefully sensed it, he caught a subtle aura utterly different from ordinary fierce fist intent.

It was the true essence of yin and yang intermingling, hardness and softness harmonized, contradiction unified!

At the center of the imprint, it was as if a singularity had perfectly compressed and condensed the extreme "yin" and extreme "yang"—two utterly opposing forces—into a single point, releasing devastating power only at the moment of explosion.

This was not mere physical destruction; it embodied the fundamental law of yin-yang generation and restraint, opposition and unity.

"This feeling…"

Chen Mu's heart stirred, "It perfectly matches the Two Yin-Yang Sword Qi!"

The Two Yin-Yang Sword Qi had only unlocked the power of the "Yin Sword"; the "Yang Sword" remained unknown, let alone the ultimate state of yin-yang unity.

Chen Mu had long sought to complete it but lacked the right opportunity or catalyst.

This fist imprint, imbued with the true essence of yin and yang, was clearly tailor-made for his enlightenment!

Chen Mu glanced around; everyone in the cave was lost in their own insights, none noticing his corner.

He immediately sat cross-legged, facing the fist imprint.

He split half his spirit to maintain basic vigilance over the outside world, while the other half focused intensely, his powerful spiritual force extending like the finest tendrils, slowly probing toward the fist imprint on the rock wall.

Hum~

The instant his spiritual tendrils touched the residual will on the imprint's surface, a powerful suction pulled him in.

Chen Mu offered no resistance; he let the suction draw that portion of his spirit away.

The scene before him abruptly shifted!

No longer the cave's interior, but a void resembling primordial chaos.

In the center of the void, a slowly rotating, starkly black-and-white "Yin-Yang Fish" pattern floated silently, brimming with infinite profundity.

This was the spiritual Illusion Realm forged from the yin-yang law essence left by the Wu Zun within the fist imprint!

"As I suspected…"

Chen Mu secretly rejoiced, fully sinking his spirit into the slowly rotating Yin-Yang Fish pattern.

He stopped analyzing specific fist techniques and instead directly perceived the fundamental truth: the flow, mutual dependence, and transformation of yin and yang qi.

These insights flowed like gentle streams, continuously merging into his understanding of the Two Yin-Yang Sword Qi.

Chen Mu attempted to integrate this yin-yang essence into his own sword path, building upon his existing "Yin Sword," reverse-engineering and constructing its opposite, radically different "Yang Sword."

The profound principles of yin-yang law slowly circulated, collided, and fused within him.

Time seemed to lose meaning.

One hour, two hours…

One day slipped away silently.

The cave remained still, save for occasional soft breaths or qi fluctuations from those who had gained insight.

The aura around Chen Mu, seated before the fist imprint, suddenly underwent a subtle change.

His previously restrained and calm aura now carried a blazing, radiant intensity, like the first rays of the rising sun.

His closed eyes snapped open—

Hiss!

A razor-sharp, crimson-gold sword qi, its edges flickering with faint flames of heat, erupted without warning, striking the empty cave wall far ahead and leaving a faint scorch mark, radiating intense heat.

"Achieved!"

Chen Mu whispered inwardly, a satisfied smile appearing on his face.

The "Yang Sword" of the Two Yin-Yang Sword Qi had been successfully completed!

Now, the Yin Sword was elusive and sharp, the Yang Sword radiant and majestic—each possessing its own unique brilliance.

After slightly calming his spirit, slightly depleted by the deduction, Chen Mu did not stop.

His gaze returned to the slowly rotating Yin-Yang Fish in the spiritual Illusion Realm.

"Though the Yin Sword and Yang Sword are each powerful, the true essence and ultimate power of the Two Yin-Yang Sword Qi lies in their unification—the 'Yin-Yang Unification Sword Qi'!"

Chen Mu's mind awakened; he immersed himself once more.

This time, he sought to fuse the newly comprehended essence of the "Yang Sword" with the long-mastered essence of the "Yin Sword," uniting these two opposing yet origin-sharing sword intents at a higher level to evolve the ultimate "Yin-Yang Unification" sword.

This process was far more difficult and perilous than completing the "Yang Sword."

Yin and yang qi possessed opposite natures; forcibly merging them risked violent conflict—or even backlash against himself.

Chen Mu proceeded with extreme caution, repeatedly simulating, deducing, and testing within the spiritual Illusion Realm.

Another day and night passed.

Deep in the cave, Chen Mu's aura alternated between icy cold and blazing heat, shifting back and forth, yet never perfectly blending, let alone merging into one.

His brow furrowed slightly—he had hit a bottleneck.

"The Wu Zun Vault opens for only three days…"

Chen Mu calculated the time in his mind.

According to past records, the vault's entrance opened for only three days; after that, the seals reactivated, trapping anyone still inside until the next opening a century later.

He had no intention of being trapped in this cave for a hundred years!

Time was running out; conventional enlightenment would likely fail to break through the bottleneck within the remaining hours.

Chen Mu's eyes hardened; he no longer hesitated, pulling out the Battle Card he had preserved all along for emergencies!

"Now…"

He silently willed it—and the Battle Card activated instantly.

A cool, profound force surged into Chen Mu's mind-sea, perfectly merging with his spiritual will.

In an instant, his thought speed, deduction ability, and depth of understanding of martial truths all surged more than several-fold!

The magical power of the Practice Card resonated wondrously with the yin-yang fish's martial truth contained in the fist imprint, producing a stunning effect where one plus one exceeded two.

The previously sluggish and obstructed key node of yin-yang fusion, under the Practice Card's enhancement, was gently stirred by an invisible hand, suddenly clearing open!

Countless subtle truths regarding yin-yang transformation, mutual dependence, balance, and unity surged into Chen Mu's heart like a tide.

In the mental Illusion Realm, the rotation of the yin-yang fish seemed to quicken slightly; the black and white hues no longer stood sharply opposed, but began to interpenetrate and merge, each within the other, ultimately dissolving into a gray halo—chaotic yet brimming with boundless vitality…

Time slipped away, second by second.

When only half an hour remained before the three-day deadline, the alternating cold and scorching qi surrounding Chen Mu, who sat before the fist imprint, suddenly retracted and calmed simultaneously.

A strange sword intent—unnameable, as if embracing all things, yet capable of dividing yin and yang—slowly rose from within Chen Mu; though it flashed and vanished in an instant, it was profoundly mysterious and profound.

Done!

The Yin-Yang Unification Sword Qi has been successfully comprehended!

Though he had only barely grasped its true meaning and method of operation, and still had far to go before true mastery, the most critical threshold had now been crossed.

At that very moment, a muffled voice came from nearby.

"Brother Chen! Time's almost up—we need to go!"
