Chapter 1077 : Supreme-Grade Lifebound Sword

Watching 6 Stars Immortal depart, Eldrin did not delay. He immediately began secluded cultivation to refine and elevate the Celestial Departure Twin Swords.

To advance to a top-grade Lifebound Immortal Treasure, 1 must resolve 3 fundamental challenges.

First, the master's cultivation must reach the Late-stage Ascendant Realm; otherwise, insufficient cultivation would naturally prevent the nurturing of the immortal sword.

Second, 1's mastery of formations must reach the Immortal-tier Upper Grade. Only an array master of this caliber could transform the laws of heaven and earth into formation patterns and deduce the innate formation patterns of an upper-grade immortal treasure.

Third, it requires a massive amount of 5 Elements essence. Without sufficient 5 Elements essence, the Immortal Sword Transformation would be unable to complete its final metamorphosis.

Among these 3 conditions, the first 1 has already been met by Eldrin (Person Name).

Although his cultivation base was insufficient, he had long since used the Primordial Purple Qi to remove the shackles from the Sky-Severing Twin Swords, allowing him to naturally transcend this barrier.

The second condition was truly arduous, for top-tier Immortal Array Masters were exceedingly rare. Without exceptional talent in the art of formations, even ordinary immortals might fail to reach such heights after hundreds of thousands of years of dedicated study.

Eldrin, blessed with extraordinary comprehension and guided by the handwritten notes left by the Mystic Heart Earth Immortal, had already transcended this step. He successfully deduced the method to elevate the Li Fire Sword of the Returning Abyss.

All that remains now is to continuously nurture and refine it, infusing it with the essence of the 5 Elements.

Now that the 5 Elements' essence has been gathered, what remains is merely a matter of meticulous refinement—a process that demands nothing but time.

Eldrin (Person Name) thus settled his mind and began devoting himself day and night to refining his Lifebound Immortal Treasure (Magic Treasure).

Immortals heed not the passage of years, and in the blink of an eye, several centuries had slipped by unnoticed.

That day, 2 streaks of sword light intertwined and soared from Verdant Chariot Mountain (Location), their razor-sharp gleam ascending like celestial dragons roaming the heavens. They circled in the sky for a long while before finally descending.

"What a fine immortal sword."

Gazing upon the Li Fire Sword of the Returning Abyss, a faint smile graced Eldrin's lips.

The Sky Severing Twin Swords truly lived up to their reputation as peerless immortal blades of unparalleled slaughter. Having ascended to the upper-grade immortal rank, their might had increased by an extraordinary degree.

Eldrin had a growing sense that if he were to unleash the combined power of the twin swords, their offensive force might surpass even the ninth level of Ascendant Immortal.

As for whether it could rival the Half-Step Earth Immortal realm, Eldrin still harbored some uncertainty—after all, he had never witnessed a Half-Step Earth Immortal in action.

"Perhaps he could already rival Elder Canyangzi and be mentioned in the same breath as the Azure Firmament Divine Maiden."

Suddenly, Eldrin recalled those peerless immortals he had once encountered in the Crimson Sun Blessed Realm.

In those days, the Azure Firmament Goddess, the Crimson Sunset Sage, and the third individual were all supreme immortals at the peak of the Ninth Ascension to Immortality.

Their bloodlines were extraordinary and their powers immense. In their hands, they wielded supreme immortal treasures like the Azure Sky Divine Thunder Mirror and the 10-1000-Mile Setting Sun Pearl. The combat prowess they unleashed could truly be described as earth-shattering.

"Now it seems..."

Eldrin murmured inwardly, then shook his head a moment later.

The combined might of the Sky-Severing Twin Swords still fell slightly short compared to the others. This was not due to any lack of power in the swords’ union, but rather because Eldrin’s (Person Name) cultivation base remained insufficient.

Eldrin (Person Name) currently possessed a cultivation base of only the Fourth Heavenly Ascension Realm. Though his immortal essence far surpassed others of the same rank, it still fell short compared to the profound depths wielded by those individuals from bygone eras.

This was not only a matter of the depth of immortal essence, but more importantly, its quality. After all, Eldrin had only recently broken through to the middle stage of Ascension with the aid of elixirs, and his immortal essence had not yet been sufficiently refined.

"However, now that the immortal sword has ascended, refining immortal essence won't be slow anymore."

Eldrin murmured inwardly, and in that instant, the Twin Celestial Parting Swords transformed into streaks of light that vanished into the brow-seal between his eyebrows.

The immortal sword followed the immortal trace into his body, continuously drawing upon the power of immortal essence. With its own supremely refined sword energy, it began to temper the immortal essence.

Eldrin lowered his gaze to sense the process, finding that although it was slow, it was far faster than refining it himself by relying on his Celestial Embryo.

Proceeding in this manner, within a 1000 years, the refinement of his Immortal Essence could reach the Middle Stage of Ascension.

Not only that, but the Sky-Severing Twin Swords were of the highest Immortal Sword grade, their quality no less than that of late-stage Ascension.

As long as he continued to refine it ceaselessly, with the feedback from the Sky-Severing Twin Swords, his immortal essence would become as pure as that of a late-stage Ascension Realm cultivator in less than 10 1000 years.

"By that time, it should be just about right."

Eldrin (Person Name) murmured inwardly before finally withdrawing his gaze.

The child of Qing Ji and Lyra (Person Name) would still take a few more years to be born, so Eldrin (Person Name) once again immersed himself in refining his spiritual power.

In his leisure time, he used the Primordial Magnetic Immortal Gold as a foundation to elevate the Yin-Yang Void Realm to the Immortal rank.

After advancing to the Yin-Yang Void Realm, Eldrin gained more means to restrain his opponents' immortal treasures. Yet, these were merely secondary applications of the mirror's void-manipulating and treasure-sealing abilities.

Eldrin shook his head. The spatial fabric of the immortal realm was far more resilient than the mortal world. Unless aided by extraordinary immortal artifacts, only Earth Immortals could carve out spatial domains, while Celestial Immortals possessed the power to tear through the void for distant travel.

With the power of the Immortal-Grade Yin Yang Void Mirror, it couldn't even tear through the void, let alone capture immortal treasures.

Unless 1 could obtain a Void Gem (Spiritual Object) of immortal rank, yet such Void Gems (Spiritual Object) were exceedingly rare. Even the lowest grade among them was considered a supreme immortal treasure—a priceless rarity that even immortals could only encounter by chance, not by pursuit.

"Very well, a single piece of Yuanci Immortal Artifact shall suffice."

"If we can find a Void Gem (Spiritual Object) in the future, we can simply fuse it within."

Eldrin thought to himself, yet vaguely sensed that once he obtained the Void Gem, this Yin-Yang Void Realm would possess the potential to evolve into a world-forging treasure.

Not long after he had advanced to the Yin-Yang Void Realm, Aoki-hime approached the moment of childbirth.

That day, Eldrin waited anxiously outside the cave abode. Only after a long while, when the cry of an infant echoed from within, did he finally step inside, his heart swelling with exhilaration.

Eldrin and Qing Ji welcomed a daughter, an infant with lotus blossoms gracing her brows—a child of jade-like bone structure and celestial elegance.

"This child is actually..."

Eldrin held the child in his arms, his heart trembling faintly as a complex expression flickered across his face.

The reason he made such an expression was not because the child lacked talent, but because her Heart Aperture was exceptionally rare.

This heart aperture was known as the 'Childlike Unyielding Heart,' a truly superior type. Cultivators possessing such a heart aperture could be considered among the most elite on the path of cultivation.

However, it possessed a flaw that caused endless headaches, for the so-called "stubborn heart" was also known as the heart of foolish obstinacy.

Cultivators endowed with such a heart aperture are invariably mischievous to the core, often courting calamity through their playful antics—so much so that they might very well pay with their lives.

The Childlike Heart of Tenacity is considered a supreme grade among all Hearts of Tenacity, for it not only possesses unyielding resolve but also retains a pure, childlike innocence.

Cultivators who possess the Childlike Heart are often pure and straightforward in nature, brimming with untainted sincerity. Their character is marked by unwavering perseverance, making them individuals of noble and lofty disposition.

When a pure heart merges with an unyielding spirit, though it bestows incomparably astonishing talent, it also brings greater peril.

They possessed the innocence and forthrightness of a childlike heart, yet also harbored the mischief and stubbornness of a playful spirit. While more prone to stirring up trouble, they would often attract calamities precisely because of the guileless purity of their childlike heart.

Childlike Tenacity of Heart!

"Now I understand why she is incompatible with the 7-Orifice Lyra (Person Name) Jade."

Qing Ji murmured softly, a faint, bitter smile gracing her lips.
