Facing the two dragons as they plunged toward him, Liu Wuxie remained perfectly calm. The two divine bows shifted simultaneously, locking onto the old man and the young man. Raising the Bloodthirst Blade, he moved it in a measured rhythm, releasing faint ripples that resonated with the surrounding air.

"Let Heaven and Earth be the composition, and the constellations its rhythm!" Liu Wuxie declared.

The old man's expression changed dramatically the instant those words rang out. Fear filled his eyes. He had transformed his soul into a melody and his body into rhythm, but that was merely an inferior path.

Only now did he understand what kind of monster stood before him. Liu Wuxie could actually use the laws of heaven and earth themselves to inscribe music.

Countless musical notes danced through the air before sinking into the depths of the divine bows. Though musical notes could also qualify as a type of talisman, they differed from ordinary talismans because they possessed no formidable offensive power. Instead, they amplified the strength of the music itself.

Artifacts possessed artifact runes, and pills possessed pill runes. Music, naturally, had its own musical notes as well.

Unable to endure the overwhelming pressure radiating from the divine bows, the descending dragons rapidly cracked apart. Countless fractures spread across their bodies. Liu Wuxie had no intention of prolonging this battle any further.

The surrounding cultivators stood frozen in astonishment, completely unable to comprehend what Liu Wuxie was doing.

Deep within the underground fight club stood a domed chamber that overlooked the entire arena. Several elderly men sat within it, each having reached the Origin Immortal Realm and possessing terrifying cultivation.

Compared to them, the Yin-Yang Elders could only be considered ordinary members of the underground fight club. They did not even qualify to stand with their true upper echelon.

"This brat is far from ordinary. He actually comprehended the musical notes of heaven and earth," remarked one Origin Immortal elder.

"Should we kill him?" another elder asked. If Liu Wuxie successfully cleared the challenge, the underground fight club would suffer tremendous losses. Yet even killing him would not recover what they had already lost.

"Leave him alone for now. He's a mentor of the Azure Flame Dao Hall and also Ye Linghan's assistant. If we kill him, Ye Linghan will undoubtedly direct her anger at us. Although we don't fear her, her father, Ye Guhai, is another matter entirely," said a white-haired elder.

As an asset of the Eastern Emperor Pavilion, the underground fight club naturally had no reason to fear Ye Guhai. However, creating unnecessary conflict served no purpose.

Although Liu Wuxie had inflicted significant losses upon the underground fight club, the ten battles had also brought them enormous profits. More than ten thousand cultivators had gathered to watch, and over eighty percent had wagered on the underground fight club's victory. Very few had believed Liu Wuxie could prevail.

The underground fight club had paid the price in blood, losing many of its fighters. Yet the staggering amount of immortal stones it earned was more than enough to offset the loss.

Within only a few hours, the underground fight club had already investigated everything concerning Liu Wuxie and Ye Linghan.

"But if the pavilion master pursues this matter, we won't be able to bear the consequences. Since when has the underground fight club ever tolerated such provocation?" Regardless of the outcome, Liu Wuxie's slaughter of so many fighters would inevitably damage the underground fight club's reputation.

"Choosing not to kill him now doesn't mean we'll simply let this matter pass. We can eliminate him another way while avoiding direct conflict with Ye Guhai," the white-haired elder replied, a cold glint flashing through his eyes.

Killing Liu Wuxie openly would tarnish their reputation, and Ye Linghan would certainly intervene. The most effective solution was to remove him quietly while staying out of Ye Linghan's sight.

As the two divine bows stretched to their limits, they resembled a pair of crescent moons suspended in the sky. The instant the bowstrings released, two arrows burst forth, producing explosive sonic booms that tore through the air.

The bone arrows lacked physical substance, yet they undeniably existed, formed entirely of soul energy.

Liu Wuxie had integrated methods from the Soul Forge Art into the arrows, granting them the terrifying ability to pierce directly into soul seas.

By now, the two musicians had exhausted the majority of their soul energy, and the Lament of the Nameless had nearly reached its conclusion. As the final note faded away, the bone arrows pierced through space itself and entered their soul seas before disappearing without a trace.

Time seemed to stop.

Everything fell silent.

Around the cage, the crowd unconsciously held their breath, not daring to disturb the stillness that had descended.

Most of the immortal energy within the desolate world had been exhausted, and the final battle had been the most demanding fight he had faced so far.

Without delay, he threw over ten thousand immortal stones into the Sky Devouring Divine Cauldron. The stones dissolved into liquid energy and poured into the desolate world. He had to keep his immortal energy replenished at all times in case unforeseen dangers arose.

As the energy flooded in, the immortal energy within the desolate world rapidly recovered to nearly seventy percent.

When Liu Wuxie got back to his feet, only a faint pallor remained on his face. Otherwise, he appeared largely unharmed.

"What a fine piece!" said the young man with great difficulty before collapsing to the ground. His body gradually withered until only a layer of skin remained.

"One song, and the heart shatters. I never imagined I would encounter a kindred soul in my final moments. Now I can die without regret. Young lad, this zither is yours," the old man said before death claimed him. No fear appeared on his face. Instead, relief filled his expression.

At the end of his life, he had heard a truly heavenly composition and, through it, comprehended a higher realm within the art of music. That enlightenment had allowed his soul to transcend.

As his final words faded, the old man tossed the six-stringed zither toward Liu Wuxie, hoping it would not disappear into obscurity.

Liu Wuxie reached out and caught it. By then, every trace of blood upon the instrument had vanished, completely absorbed into the zither itself.

Shock flickered across Liu Wuxie's face as he looked at the three engraved characters upon the instrument, "The Heavenly Severance Zither!"

Although the attack had pierced his soul sea, the old man did not die immediately. At most, he still had a dozen breaths remaining.

Liu Wuxie had never expected the long-lost Heavenly Severance Zither to end up in the possession of a mere True Immortal. The discovery left him genuinely stunned. While the Heavenly Severance Zither itself was not a heaven-defying artifact, its creator had been the Heavenly Severance Elder, an Immortal Venerable Realm expert.

Longevity Wood, an incomparably rare material, formed the body of the zither. Across the entire celestial realm, one would not find even one or two Longevity Trees. Using such wood to forge a zither was extravagance beyond measure.

The value of the zither's body alone was immeasurable, let alone the fact that an Immortal Venerable had personally forged it.

"You know my ancestor?" the old man asked, astonishment filling his face. His ancestor, the Heavenly Severance Elder, had indeed forged the Heavenly Severance Zither.

Following the disappearance of the Heavenly Severance Elder, the zither remained within his bloodline and was passed down from generation to generation. Sadly, his descendants grew progressively weaker over time, and none possessed the ability to return the Heavenly Severance Zither to its former splendor.

At the mention of his ancestor, guilt surfaced across the old man's face.

"Heavenly Severance was without attachment, while longevity stretched on eternally," Liu Wuxie murmured as his fingers gently brushed across the Heavenly Severance Zither.

In the eyes of any zither master, it was a flawless work of art. Every inch of its body had been crafted with unparalleled precision.

Clearly, the Heavenly Severance Elder had poured immense effort into creating this masterpiece. Calling him the greatest zither master was hardly an exaggeration.

"Let me use a Song of Longevity to send you on your way," Liu Wuxie said.

He sat down, placed the Heavenly Severance Zither across his lap, and began to play.

The Song of Longevity expressed a yearning for eternal life, yet how many in this world could truly attain longevity? Its melody flowed like the song of the sea, the chirping of birds, the swaying of trees, and drifting clouds beneath an endless sky.

The cultivators gathered around them all entered a strange state. Some burst into tears, some wept silently, some laughed, while others sank into grief.

Two streams of tears slid down Ye Linghan's cheeks as thoughts of her mother surfaced in her mind.

Even the elders seated within the domed chamber looked shocked. The Song of Longevity possessed no offensive power whatsoever, yet it could draw forth the goodness hidden within a person's heart and wash away the darkness lingering inside them. Those who cried had done so because they witnessed the darkness within themselves.

A smile appeared on the old man's face as he slowly collapsed to the ground.

He died without regret.

When the final note faded away, Liu Wuxie exhaled deeply. He had never expected the Heavenly Severance Zither to possess the ability to refine his soul. The discovery left him deeply surprised. It meant he could use the zither in the future to further evolve his primordial spirit.

A beautiful melody truly had the power to transform a person's soul.

With a wave of his hand, Liu Wuxie stored the old man's corpse away. He chose not to refine it. Instead, he intended to find a quiet place and bury him properly. He also placed the Heavenly Severance Zither into his interspatial ring.

The world only knew that the Heavenly Severance Elder had forged the Heavenly Severance Zither. Few realized that he had poured his entire life's effort into it. That fact suggested the instrument likely concealed a great secret. With so many people watching, Liu Wuxie had no intention of investigating it immediately.

The Heavenly Severance Elder had not only stood unrivaled in the art of the zither; he had also been a supreme expert in the blade.

"Can I leave with them now?" Liu Wuxie asked.

The iron gate never reopened, signifying that he had successfully passed the life gate challenge.

The Yin-Yang Elders remained silent.

Their silence was answer enough.

When the iron gate nearest to Liu Wuxie slowly opened, he stepped out at an unhurried pace. The moment he emerged, Ye Linghan rushed forward, ready to guard against any possible sneak attack.

Meanwhile, Diao Jiuzhi, Liang Han, and Ren Fanfan were so overwhelmed with joy that tears streamed down their faces. They grasped Liu Wuxie's arm tightly, gratitude filling their expressions. Without him, all of them would have died there today.

"Don't speak. Let's return immediately," Liu Wuxie said.

He led them swiftly through the crowd toward the surface.

By the time they emerged, dawn had already illuminated the eastern horizon. Without realizing it, they had spent an entire night underground.

Despite that, the underground fight club remained crowded and lively. Everywhere, people discussed the challenge they had just witnessed, especially the Song of Longevity. The memory of that melody lingered in their minds, leaving them deeply awestruck.

After reaching the surface, Liu Wuxie suddenly accelerated his pace. As he passed through an alleyway, he spat out a mouthful of blood.

Although he had defeated the two musicians in the final battle, the clash had still inflicted a slight shock upon his soul sea. The injury was not serious, but a pill that could nourish the primordial spirit would greatly help.

"The Lament of the Nameless truly lives up to its reputation," Liu Wuxie murmured.

After expelling the clotted blood, his complexion visibly improved.

"Wuxie, how are you?" Ye Linghan asked anxiously as she hurried over to inspect him.

After examining him carefully, she discovered no major injuries. Even the wounds he had previously suffered had already healed completely.

"I'm fine. My soul suffered a little impact, so I need to buy the Soul Healing Pill," Liu Wuxie said.

As long as he refrained from excessive use of soul energy, the injury would not affect him significantly.

"The Soul Healing Pill is a fourth-grade immortal pill, and it's extremely rare on the market," Ye Linghan said. Though she was not an alchemist herself, she had studied extensive alchemical knowledge since childhood. The Soul Healing Pill was a fourth-grade immortal pill comparable to the Spirit Immortal Realm, and only a handful of individuals within the Azure Flame Dao Hall possessed the qualifications to refine it.

Furthermore, the formula for the Soul Healing Pill had vanished since ancient times. Without the formula, even a willing alchemist could not produce it.

Although the Soul Healing Pill was only a fourth-grade immortal pill, its refinement was actually more difficult than many fifth-grade immortal pills capable of healing soul injuries. Most alchemists disliked refining it because its effects were highly specialized, while the process itself remained exceptionally complicated. It was no wonder Ye Linghan looked so troubled.

Fortunately, the damage to Liu Wuxie's soul sea was relatively minor. With the Heavenly Dao Book's assistance, he could fully recover within a month. Because of that, he felt no urgency. If he failed to purchase a Soul Healing Pill, he could refine one himself. And if that proved impossible as well, he would merely wait a month for a complete recovery.
