460: Upgrade the Soul-Devouring True Spirit Sword

With a slight thought,

that Medicinal Pill, flowing with nine-colored starlight and appearing like a condensed crystal of the galaxy, moved out from the Primordial Spirit space.

It hovered before him, the nine spiritual patterns on its surface flowing like living creatures!

Without hesitation, he inhaled, and the dragon-eye-sized treasure pill transformed into a warm stream of light that vanished down his throat.

Boom!

An unprecedented warm current exploded throughout his limbs and bones!

This warm current was not as violent as solar flames, but was extremely mellow, like the first breath of the Universe nourishing all things.

Carrying strands of cool, clear invisible energy, it ignored the barriers of the Meridians and surged directly toward the Dantian sea!

Soft ripples instantly spread across the surface of the newborn Primordial Spirit, like a thirsty divine sprout touching heavenly rain.

It vibrated slightly involuntarily, spontaneously absorbing this power of Origin nourishment!

"Still not enough!" A divine light flashed in Yao Delong's eyes.

A small bottle, translucent like a flawless teardrop, appeared in his palm—a gift from the Moyan Sect, ten drops of Ten-Thousand-Year Spiritual Pith!

The moment he uncorked it, a vast and pure aura originating from an ancient Spiritual Vein filled the entire Secret Chamber.

From the mouth of the bottle, a drop of milky-white nectar, like a liquid star with endless runes appearing and disappearing within, slid out.

Yao Delong sent it into his mouth without hesitation.

The Ten-Thousand-Year Spiritual Fluid entered his throat!

Like the Nine Heavens' Milky Way bursting its banks, an unimaginably vast and pure spiritual power, carrying fragments of world-opening dao rhyme,

forcefully injected into the warm current previously formed by the pill's power!

In an instant, the Dantian turned into a towering wave! The warm current became a stellar furnace refining star remains!

Endless energy, mixed with pure medicinal properties, washed over and tempered the newborn Primordial Spirit in a manner both crude and miraculous!

"Using the spiritual pith as a guide, I draw forth the medicinal properties of the Nine Tribulations Divine Fortune to forge the divine Foundation of my Primordial Spirit!"

Yao Delong gritted his teeth and shouted low, the Nine Yang Heaven Burning Art circulating frantically.

The Dantian sea transformed into a furnace, with the crimson-gold Primordial Spirit suspended at its core, receiving this dual baptism of violence and nourishment.

The sea of the Primordial Spirit began to rotate and condense at a visible rate, the crimson-gold light within becoming increasingly pure and dazzling!

The extremely subtle energy patterns on the surface of the Primordial Spirit, unavoidable due to its new birth,

were being slowly smoothed and closed under the washing of the medicinal and spiritual pith's power, the Foundation being hammered into something indestructible!

Every time the medicinal power showed signs of weakening, Yao Delong swallowed another drop of Ten-Thousand-Year Spiritual Pith without blinking!

He did not seek an instantaneous surge, but only to extract every single bit of the Nine Tribulations Divine Fortune Pill's medicinal properties and integrate them into the deepest part of his Primordial Spirit!

As days and nights passed, even the light of the crimson crystals seemed to dim slightly, absorbed during this refining process.

A full half-month passed in silent suffering and transformation.

Finally!

"Buzz—!"

A clear, resonant hum that could only be heard on the level of the Primordial Spirit echoed from deep within Yao Delong's Dantian!

He suddenly opened his eyes!

Two streaks of crimson-gold divine light, nearly solidified and shooting out more than three feet, erupted from his pupils!

Wherever the divine light passed, the free-floating fire element essence in the Void Realm was instantly ignited, turning into two scorching, wildly dancing fire snakes!

The ancient rune Formations carved on the inner walls of the Secret Chamber sensed this surging Divine Soul power and instantly lit up like the rising sun!

Within the Primordial Spirit space, that crimson-gold ocean had already become several times deeper and more vast!

The Primordial Spirit itself, seated at the center, had not grown much in size, but its light had evolved from "dazzling" to "divine"!

A perfect glow, like cast divine gold, flowed over its surface, and the Primordial Spirit's features became increasingly clear and vivid,

carrying a mysterious majesty that overlooked the heavens and earth and controlled the Laws.

Internally, the Primordial Spirit's structure was condensed to the extreme; as the Divine Thought circulated, Great Dao runes seemed to flicker in and out of existence!

"The Primordial Spirit Origin... has likely increased by more than fifty percent!"

Yao Delong was shaken and delighted. With a slight movement of his Divine Thought, instantly!

Within a hundred miles, the heaven and earth Origin Qi surged joyfully, gathering toward the Immortal Cave like a river flowing backward!

The vastness of the world power he could mobilize, compared to when he first achieved Soul Transformation, was truly the difference between a trickling stream and a surging river!

The resonance of the Laws induced by his every move was several times clearer and more profound!

This was not just an increase in power, but a leap in insight into the essence of the world's operation!

His gaze swept over the "star clusters" floating within the Primordial Spirit space,

and his sharp vision landed on that most piercing and eye-catching "cold light"—the Innate Taibai Gengjin Essence!

"Into which sword should I fuse it?" A small dilemma emerged in his heart.

The chixiao sword had accompanied him through breaking demon remains and braving the Lightning Tribulation; their minds were already long connected,

and it was even imprinted with the Haoyang Sword Intent of his Nine Transformations of the Vast Sun.

But the soul devouring true spirit sword... was of a higher rank, more powerful, and more sinister!

This supreme grade heavenly artifact demon sword was pitch black all over, with a hideous skull embedded in the hilt and blue-gray Death Qi wandering along the blade!

"Chixiao is fierce and violent, like a blazing sun burning the sky! Soul Devouring is ferocious and treacherous, like the Nine Netherworlds devouring Souls!"

Yao Delong's gaze was deep, his mind racing.

"Now that I have condensed the wonders of the Thousand Mechanisms Formless Art's source core and my Primordial Spirit has greatly advanced, wielding this supreme grade heavenly artifact is no longer difficult!

Its specialized ability to slay and destroy Souls is a perfect match for my Heart Sword Power!"

"Moreover, the world's Evil Qi is also a derivative of the Great Dao.

In the Soul Transformation realm, it is not impossible to peer into the mysteries of the Dao of Evil!

My, Yao Delong's, Dao is never defined by others!"

Once his mind was made up, there was no more hesitation.

With a wave of his hand, a longsword with an ancient design yet exuding a Soul-penetrating evil aura appeared.

It was indeed the soul devouring true spirit sword!

The sword body was as black as ink; as soon as it appeared, the temperature in the Secret Chamber plummeted,

even the scorching aura within the room weakened a bit, and the air filled with invisible resentment and the power to pull at Souls.

Especially the hollow-eyed skull at the hilt, which emitted a chilling Death Qi that could freeze one's Soul.

"Today, I shall use the peerless purity of Gengjin to forge your true fangs!"

Yao Delong flicked his finger, and that grain of Innate Taibai Gengjin Essence, which possessed such sharp edges that it even made the Primordial Spirit feel a stinging pain,

transformed into an indescribable wisp of bright silver light and landed with pinpoint accuracy into the pitch-black eye sockets of the skull!

Buzz—!!!

It was not the sound of metal clashing, but a deep and eerie Soul ripple that suddenly rippled out!

The hollow eye sockets of the skull erupted with terrifying, blazing white light!

In an instant, the light swallowed the Gengjin essence within the eye sockets!

The entire demon sword trembled violently, emitting a sharp and unpleasant buzzing,

as if a peerless malevolent object that had slept for billions of years had been infused with a new Soul!

The Death Qi flowing on the sword body instantly intertwined and coiled fiercely with that blazing white Gengjin light!

The pitch-black Death Qi, like a living creature, greedily wrapped around, devoured, and fused with the all-destroying sharp attributes of the Gengjin essence!

Inside the sword body, countless runes seemed to be collapsing and reorganizing, born anew amidst destruction!

Visibly, the patterns on the surface of the hilt's skull seemed to come alive,

twisting to firmly "swallow" and imprint that patch of blazing white!

The black of the entire sword body became deeper and more restrained, and at the edges of the flowing blue-gray Death Qi,

a layer of cold, sharp, and barely perceptible silver edging was quietly infused!
