Chapter 329. Advancing to the Refining Devil Immortal Sword

He selected a low-grade, fourth-tier defensive magic treasure and handed it to Elder Qingci, then asked casually, "By the way, have you kept in touch with Miss Yu over the years?"

"She had been away from Ji Province for many years and had yet to return."

Qingci Sanren shook his head, then stole a discreet glance at Eldrin (Person Name).

As early as 1 100 years ago, Yu Qingyan had already reached the False Core Realm. Later, within the ruins of The Vast Sea (Location), she reaped substantial gains and obtained her share of the spoils.

After that battle, Yu Qingyan acquired a Jiejin Treasure and, leveraging her unique spiritual root constitution, broke through to the Golden Core Realm.

After her breakthrough, Eldrin (Person Name) had invited Yu Qingyan to join the Chen Family, but she ultimately declined.

Others were unaware of the specific reasons, but Elder Qingci roughly understood that Yu Qingyan most likely wished to avoid facing Eldrin (Person Name) and Lyra (Person Name).

Such a man of peerless elegance already had a Dao Companion. Meeting him would only unsettle the heart—better to admire the moon reflected in water than to seek its source.

After breaking through to the Golden Core realm, Yu Qingyan had already departed from Ji Province. From that moment onward, she never set foot in the Chu Kingdom again.

"May her journey across the lands be smooth and fortunate." Eldrin sighed softly, then let his thoughts drift away.

After Qingci Sanren and his daughter departed, Eldrin once again focused his mind on deducing the secrets of the spiritual treasure.

Thus time flew by, and in the blink of an eye, over a year had passed. Suddenly, the sky darkened with thick clouds, as rolling tribulation clouds swept across the horizon.

"It's the Demon-Smiting Heavenly Tribulation!"

Eldrin was jolted from his cultivation, gazing at the tribulation clouds gathering in the sky as an irrepressible delight dawned upon his face.

At the same time, within that secluded cultivation chamber, a dazzling white sword radiance soared into the heavens, piercing through the clouds above.

Lyra then emerged from the seclusion chamber, her expression grave as she watched the crisscrossing sword auras dancing across the sky.

"It should be fine."

Lyra's expression was tense, tinged with a hint of gravity.

Unlike the Glazed Armor of the 3 Treasures (Magic Treasure), although it is a spiritual treasure, it is not a life-bound spiritual treasure. Its potential is limited and it cannot receive the Enlightenment Lightning Tribulation from the will of heaven and earth.

The Heaven-Sundering Immortal-Slaying Sword was his Natal Spirit Treasure. A demon-refining immortal sword of this caliber faced a truly terrifying heavenly tribulation, 1 so powerful that it could potentially shatter a Natal Spirit Treasure with slightly inferior materials.

It was precisely for this reason that Lyra sought to integrate the Star Fragment, enhancing the material composition of the Celestial Ruins Immortal-Slaying Sword.

Seeing Lyra’s concern, Eldrin took her hand and reassured her, “Do not worry. Since this sword has been fused with the Star Fragment, its material alone is enough to withstand the heavenly tribulation.”

"Hmm."

Lyra nodded. She truly had ample confidence, though it was only natural to feel somewhat nervous when the moment was at hand.

After all, should this sword shatter, it would mean her centuries of arduous refinement would come to naught, and along with it, the invaluable Star Fragment (Spiritual Object) would be destroyed.

Boom—

In that very instant, a thunderous tribulation cracked across the sky, descending with unparalleled force as if intent on shattering the Demon-Slaying Immortal Sword in 2.

The Heaven-Void Immortal-Slaying Sword, however, showed no fear. With a resonant clang, it erupted in a dazzling blaze of sword radiance, cleaving directly toward the heavenly tribulation. Astonishingly, it severed the thunderous calamity into nothingness.

Not only that, the unparalleled sword radiance of this Heavenly Ruins Immortal-Slaying Blade cleaved through the void, leaving a sword scar stretching nearly a 1000 miles, and forcibly split the vast tribulation clouds in 2.

After completing all this, it bathed in the sea of lightning and soared upward, actually flying into the thunderous ocean of the tribulation clouds, enduring the baptism of countless heavenly bolts.

The scene unfolding before them was so astonishing that every cultivator in Yu County witnessed the resplendent immortal sword blazing across the heavens.

"Excellent!"

Lyra (Person Name) exclaimed in admiration, "With a single sword strike that cleaves through a 1000 miles of void and splits the majestic mountains and rivers—this is the true essence of the Demon-Slaying Immortal Sword!"

The heavenly tribulation of thunder raged for a full 3 days. Finally, from the boundless sea of lightning, a brilliant sword radiance descended, transforming into a 3-foot immortal blade that landed before Lyra (Person Name).

Master!

The Immortal Sword has a spirit, and a clear, cold voice echoed from within.

Eldrin watched silently, a flicker of astonishment flashing deep within his pupils.

Before him, this immortal sword measured a mere 3 feet, yet the power it contained was sufficient to cleave a primordial mountain towering thousands of miles high with a single strike.

Such a peerless Slaughter Immortal Sword, upon awakening of its own accord, unleashed a devastating might capable of annihilating all in its path—even posing a threat to a Nascent Soul True Monarch whose aura could overshadow mountains and rivers.

Most crucially, as the sword's master, Lyra (Person Name) could unleash the Li Fire Sword of the Returning Abyss (Magic Treasure)'s full power with her Golden Core cultivation.

Moreover, even if the sword's power were to be depleted, Lyra (Person Name) could replenish its full might by nurturing it with her spiritual energy.

Compared to treasures like the Glazed Armor of the 3 Treasures (Magic Treasure) that could only be barely activated once every 60 years, or the Mirror of the Vast Heaven (Magic Treasure) which required a full century to regain its combat efficacy after a single use, their deterrent power simply existed on an entirely different level.

After all, although the Glazed Armor of the 3 Treasures (Magic Treasure) and the Mirror of the Vast Heaven (Magic Treasure) were formidable, without a Nascent Soul cultivator nourishing them with Nascent Soul Qi (Spiritual Root), the cost of each battle became too great. If excessively depleted, they would inevitably fall into deep slumber.

"This time, you have advanced to the Refining Demonic Immortal Sword, and from now on, when you slay demons and vanquish evil, you will undoubtedly be unstoppable."

Lyra took the Heaven-Sundering Immortal-Slaying Sword and caressed its blade with delight, saying, "With you guarding my path, my cultivation journey ahead shall be somewhat smoother."

The Immortal Sword remained silent, offering no further words.

Although this kind of artifact spirit possessed intelligence no different from ordinary humans, its nature remained inherently more aloof and detached.

Putting away the Heavenly Ruins Immortal-Slaying Sword, Lyra quietly sensed for a moment before opening her eyes and remarking, "This Demon-Refining Immortal Sword possesses remarkable efficacy in tempering spiritual power."

"Oh?"

Eldrin's eyes flickered slightly, revealing a questioning expression.

Lyra nodded and said, "With the refinement from the Demon-Slaying Immortal Sword, my magical power can be further purified. It should make my spiritual energy significantly more refined."

Listening to her account, Eldrin’s face lit up with astonishment and delight.

Lyra had forged the Innate Great Luo Golden Core, and the purity of her magical power was already approaching 60 to 70 percent of a True Monarch's Nascent Soul.

Now, having undergone the tempering of the Refining Demon Immortal Sword once more, wouldn't the purity of her magical power rival that of a true Earthly Infant Nascent Soul?

Lyra shook her head and continued, "True Monarchs also temper their Natal Spirit Treasures. Moreover, an Earth-Flavor Nascent Soul likely possesses more than 1 Natal Spirit Treasure. My magical power probably still cannot compare to that of an Earth-Flavor Nascent Soul."

"Even if it cannot compare to a true Earth Path Nascent Soul, once the tempering is complete, it should be no weaker than a Human Path Nascent Soul."

Eldrin's eyes flickered slightly. Even so, this was already quite astonishing.

The reason why Nascent Soul True Lords can utilize 1 unit of magic power as if it were 2 lies in the fact that their magic power is far more refined and profoundly mysterious.

Channeling the supreme art 'Divine Light of the 5 Void Tribulations (Cultivation Art)' at full power, a Nascent Soul cultivator would expend merely 20 percent of their spiritual energy, whereas Lyra (Person Name) required a full 50 percent.

However, after being refined and tempered by the backlash from the Demon-Subduing Immortal Sword, Lyra's (Person Name) magical power would become so pure and profound that it would rival that of a Nascent Soul True Monarch. By then, activating the Divine Light of the 5 Void Tribulations (Cultivation Art) would only require 20 percent of her energy.

Such pure and profound spiritual power was bound to greatly enhance Lyra's strength, making her no less formidable than a Nascent Soul True Monarch.

By then, the only differences between her combat prowess and that of a Nascent Soul True Monarch would lie in the True Monarch's integration of their Innate Great Supernatural Power and the profound mysteries of Nascent Soul Qi (Spiritual Root).

However, with the support of the Ren Shui Qing Lotus Platform and the compensation from the 2 Demon-Subduing Supreme Treasures, it is likely that by the time she breaks through to the ninth level of the Golden Core Realm, Lyra (Person Name) will be comparable to a Human Path Nascent Soul True Lord, with the potential to not only contend against 1 but even emerge victorious in battle.
