The Immortal Physician's Transmigration: Miraculous Rejuvenation

Ye Yuanchen stared at the surging dark guards ahead, his eyes showing no fear, only unwavering determination. "Everyone, today is the battle that will decide the fate of the Spirit Realm. We must give it our all!" His voice echoed like a bell in the dark hall, inspiring his companions.

Mu Wanyue nodded gently, flicking her spirit whip, which instantly emitted a soft pink light, contrasting sharply with the surrounding darkness. "Yuan Chen, don't worry, we will fight alongside you until death."

Lu Zixuan swiftly set up a complex array beneath everyone's feet. The array shimmered with light, counteracting the dark aura emanating from the Dark Guardians. "This array is called the 'Spirit Realm Guardian Demon-Slaying Array.' It can enhance our attack and defense while weakening the enemy's strength. Everyone, fight within the array and cooperate with each other."

Bai Youruo took a deep breath, placed the Spirit Flute to her lips, and played a stirring tune. The flute's sound transformed into sharp sonic blades, weaving through the ranks of the Dark Guardians and disrupting their movements.

The Dark Guardians roared and brandished their dark longswords as they charged towards Ye Yuanchen and his companions. Their attacks flashed through the air like black lightning, carrying a dense aura of darkness, tearing the very fabric of space apart wherever they went.

Ye Yuanchen took the lead in meeting the enemy, unleashing an upgraded version of the "Spirit Realm Radiant Sun Soul-Breaking Technique"—the "Spirit Realm Holy Radiance Demon-Breaking Technique." His entire body was enveloped in golden light, and his immortal sword danced, creating a series of dazzling sword shadows. Each sword shadow contained powerful light and purifying energy, colliding with the dark guard's dark longsword and producing a deafening roar.

Mu Wanyue nimbly wielded her spirit whip, unleashing a magical technique called "Spirit Dance Illusion Whip Technique." In her hands, the spirit whip moved like a nimble sprite, sometimes transforming into a pink dragon that coiled around the limbs of the dark guards, restricting their movements; at other times, it split into countless tiny whip shadows, lashing at the dark guards like raindrops, making them impossible to defend against.

Lu Zixuan continuously adjusted the spiritual energy output of the formation, infusing his soul power into it to make its attacks even more ferocious. From time to time, beams of spiritual energy containing soul-piercing impacts shot out from the formation. These beams, upon striking the Dark Guardians, not only damaged their bodies but also directly impacted their souls, plunging them into brief confusion.

Bai Youruo's flute music grew increasingly soaring as she played the "Soul-Shattering Melody." The sonic blades within the flute music became even sharper, capable of piercing directly through the dark armor of the Dark Guardians and severing their souls. Under the influence of the flute music, some of the weaker Dark Guardians began to painfully cover their ears, their souls feeling as if they were being scorched by flames.

However, the Dark Guardians were not without a fight. They gradually adapted to the rhythm of Ye Yuanchen and his group's attacks and began to adjust their tactics. One group of Dark Guardians formed a dark sword formation, their dark longswords connecting to create a black energy barrier that blocked Ye Yuanchen's sword shadow attacks. Another group of Dark Guardians cast a dark spell, summoning a swarm of dark ghosts. These ghosts were ethereal and could move freely in the darkness; they pounced on Mu Wanyue and her group, attempting to break through their defenses.

Seeing this, Ye Yuanchen immediately changed tactics. He concentrated his light power at the tip of his sword and then unleashed an enhanced version of "Spiritual Light Shield-Breaking Thrust"—"Spiritual Saint Demon-Slaying Thrust." A thick golden beam of light shot from his hand, like a giant spear of light, piercing straight towards the sword formation of the Dark Guardians. This beam of light contained powerful penetrating force, instantly shattering the Dark Guardians' energy barrier and sending them flying from the sword formation.

Facing the attacks of the dark phantoms, Mu Wanyue remained calm and composed. She unleashed a magical technique called "Spiritual Illusion Whip Shadow Array," wielding her spirit whip with impenetrable force, forming a pink whip shadow array. Within the array, the spirit whips were like sharp blades, slicing down the attacking dark phantoms one by one. The dark phantoms let out shrill screams and vanished into wisps of black smoke.

Lu Zixuan increased the infusion of his soul power into the formation, shifting its focus to the Dark Guardians who were casting dark magic. The spiritual energy arrows fired from the formation became denser, and each arrow carried a powerful soul-binding force. Upon striking the Dark Guardians, these arrows instantly bound their souls, slowed their bodies, and rendered them unable to cast dark magic.

Bai Youruo's flute playing suddenly shifted, changing from the stirring "Spiritual Melody of Soul Destruction" to the soothing "Spiritual Melody of Soul Calming." The sound waves from the flute transformed into a gentle power, enveloping everyone and calming their souls while restoring their spiritual energy. At the same time, this sound wave also weakened the Dark Guardians' fighting spirit, rendering their attacks feeble.

With the combined efforts of Ye Yuanchen and the others, the Dark Guardians gradually found themselves at a disadvantage. But just as they were about to be completely defeated, the Dark Crystal Ball suddenly erupted with a powerful dark force, which swept towards Ye Yuanchen and the others like a black tsunami.

Ye Yuanchen sensed the terrifying power of this dark force; he knew it was the final struggle of the source of darkness. He took a deep breath, fusing all his light power, soul power, and immortal medical skills together, unleashing his strongest move—the "Spirit Realm Light Saint Healer's Source-Breaking Technique." He gripped his immortal sword with both hands, raised it high, and then slashed fiercely down at the dark force. A massive golden blade of light shot out from his hands, containing the breath of life, the hope of light, and unwavering faith.

Mu Wanyue, Lu Zixuan, and Bai Youruo also unleashed their strongest powers, converging them on Ye Yuanchen to amplify his attack. With their combined strength, the dark power was temporarily repelled.

However, the dark crystal ball did not stop releasing dark power; instead, it continuously unleashed even more powerful dark energy, attempting to completely engulf Ye Yuanchen and the others. Ye Yuanchen and his companions were caught in a fierce battle; their spiritual energy was constantly being depleted, and their bodies were gradually becoming exhausted.

In this critical moment, Ye Yuanchen suddenly recalled the vision of the origin of the Spirit Realm he had seen in the Heavenly Palace of the Spirit Realm. He realized that the existence of the Source of Darkness violated the natural order of the Spirit Realm, and only by using the power of the Spirit Realm's origin could it be completely destroyed.

He closed his eyes, calmed his mind, and used his spiritual sense to explore the primal power of the spirit world. After some effort, he finally sensed the existence of the primal power of the spirit world. He connected his soul with the primal power of the spirit world and then guided the primal power towards the dark crystal ball.

Mu Wanyue, Lu Zixuan, and Bai Youruo also sensed Ye Yuanchen's intentions. They all connected their souls with Ye Yuanchen's, jointly guiding the power of the spirit realm's origin. Under the powerful impact of the spirit realm's origin power, the dark crystal ball began to crack.

As the cracks widened, the dark crystal ball finally shattered with a deafening roar. The source of darkness was completely destroyed, and the dark aura within the dark hall dissipated. Ye Yuanchen and the others had successfully saved the Spirit Realm, and their names would forever be remembered by all the races of the Spirit Realm.

After the source of darkness was destroyed, Ye Yuanchen and his companions stayed in the Spirit Realm for a period of time, helping the various races of the Spirit Realm rebuild their homes destroyed by the dark forces. They shared their experiences and insights gained in battle with the younger generation of the Spirit Realm, hoping that they could better protect the Spirit Realm.

After a period of rest, Ye Yuanchen and the others decided to return to the cultivation world and the mortal world. Carrying the friendship and blessings of the spirit world, they passed through the gates of the spirit world and returned to their familiar world. They knew that in the days to come, they would continue to shoulder the mission of protecting world peace and justice, and embrace new challenges and opportunities.
