The Immortal Physician's Transmigration: Miraculous Rejuvenation

While Ye Yuanchen and others were actively spreading the secrets of the spirit world and promoting cooperation between the cultivation world and the mortal world to jointly guard against dark forces, a new dark shadow was quietly spreading.

In a remote borderland, a peaceful little village lived a tranquil life. The villagers worked at sunrise and rested at sunset, while cultivators diligently practiced their arts in the nearby mountains, coexisting peacefully with the villagers. However, one night, the sky was suddenly shrouded by an eerie dark cloud, within which flickered eerie purple lightning. Then, a dark aura swept in like a tidal wave.

The villagers awoke with a start, horrified to find that some familiar faces had become twisted and grotesque, their eyes gleaming with malevolence. These villagers, corrupted by dark forces, began to attack their relatives and neighbors in a frenzy, emitting strange, hissing cries.

Upon noticing the anomaly, nearby cultivators rushed to their aid. However, they were astonished to discover that the villagers, corrupted by darkness, possessed physical strength far exceeding that of ordinary people; ordinary magical attacks could only cause minor harm. Furthermore, during the battle, dark energy continuously surged from the villagers' bodies, forming black tentacles that entangled the cultivators' weapons and bodies, weakening their spiritual power.

A young cultivator attempted to trap a corrupted villager using his magic. He cast a spirit rope spell, which transformed into a beam of light and flew towards the villager. However, the moment the rope touched the villager, a dark aura rapidly spread along it, instantly corroding it completely. The young cultivator was terrified and, before he could react, the villager pounced on him, his sharp claws slashing a deep wound on his arm.

On the other side of the village, an experienced elder cultivator sensed the unusual nature of this dark power. He used his spiritual sense to investigate and discovered that the dark aura contained a familiar evil force—the aura of the Dark Night Demon Lord. However, this aura was different from before, seemingly having undergone some kind of mutation and enhancement.

"Could it be that the Dark Night Demon Lord did not completely disappear, but was reborn in some way?" An ominous premonition welled up in the elder's heart.

Knowing the gravity of the situation, he immediately summoned nearby cultivators to form a defensive line in an attempt to stop the spread of the dark forces. The cultivators cooperated with each other, unleashing various immortal techniques. Some released powerful spiritual energy shields, while others launched offensive immortal techniques, trying to separate the corrupted villagers from the uncorrupted ones.

However, the attacks of the dark forces grew increasingly fierce. The dark energy gradually converged, forming a massive dark vortex. Within the vortex, a blurry figure gradually emerged—the reborn body of the Night Demon Lord. His body radiated an even more intense dark light, his eyes filled with hatred and greed.

"Do you think you can easily destroy me? I have drawn even greater power from the abyss of darkness, and now, this world will once again be my domain!" The Night Demon Lord let out a maniacal laugh, his voice echoing throughout the entire village.

After his rebirth, the Dark Night Demon Lord's power increased dramatically. With a wave of his hand, countless black energy beams shot out from the dark vortex. These energy beams struck the cultivators' shields like black lightning, causing the shields to tremble under the impact. Some cultivators could not withstand the powerful impact and were blasted away by the energy beams, suffering serious injuries.

At this critical moment, Ye Yuanchen and the others learned of the crisis in the border village. They immediately put aside their work and rushed to the scene. When they arrived, the sight before them shocked them greatly.

Seeing the reborn body of the Dark Night Demon Lord, Ye Yuanchen was filled with anger and regret. "I never thought that our previous efforts would still fail to completely eliminate him. This time, we must not let him succeed again!"

Without hesitation, he unleashed the "Spirit Realm Holy Radiance Demon-Slaying Technique," his entire body enveloped in golden light as he charged towards the Dark Night Demon Lord. Mu Wanyue, Lu Zixuan, and Bai Youruo quickly joined the battle. Mu Wanyue wielded her spirit whip, which spun like a pink dragon, weaving through the dark energy beams in an attempt to disrupt the Dark Night Demon Lord's attacks. Lu Zixuan swiftly set up a soul array on the battlefield; once complete, beams of spiritual energy imbued with soul power shot towards the Dark Night Demon Lord. Bai Youruo played her spirit flute, the notes transforming into sonic blades that sliced ​​through the dark aura surrounding the Dark Night Demon Lord, weakening his defenses.

However, the Dark Night Demon Lord seemed to have anticipated their attack. A black shield appeared around his body, which not only blocked the attacks from Ye Yuanchen and the others, but also absorbed some of the attack energy and converted it into his own power.

"Your attacks are too weak. Before my newly acquired power, you are nothing but ants!" the Dark Night Demon Lord said mockingly.

Ye Yuanchen knew that he had to find the Dark Night Demon Lord's weakness to defeat him. While fighting, he used his spiritual sense to carefully examine the Dark Night Demon Lord's body. In the midst of the fierce battle, he discovered that although the Dark Night Demon Lord's reborn body was powerful, his soul seemed not to have fully merged with his new body, leaving some subtle gaps.

"Everyone, focus your attacks on the gap in his soul!" Ye Yuanchen shouted.

Upon hearing this, Mu Wanyue, Lu Zixuan, and Bai Youruo immediately adjusted their attack strategy. Mu Wanyue unleashed a celestial technique that enhanced soul attacks, shifting the focus of her spirit whip's attacks towards the Dark Night Demon Lord's soul rifts. Lu Zixuan added special soul-targeting attack runes to his soul array, allowing his spiritual energy arrows to more accurately strike the Dark Night Demon Lord's soul weaknesses. Bai Youruo played an enhanced version of the "Spiritual Sound Soul-Shattering Melody," the sonic blades within her flute music becoming even sharper, piercing directly towards the Dark Night Demon Lord's soul rifts.

With everyone's combined efforts, the Dark Lord's soul was severely damaged. He let out a painful roar, and cracks began to appear in the dark shield surrounding his body. But he did not back down; instead, he became even more frenzied.

The Dark Lord unleashed a forbidden dark magic, merging his body with a dark vortex to transform into a colossal dark monster. This monster possessed countless tentacles, each capable of releasing powerful dark energy. It opened its blood-red maw and lunged at Ye Yuanchen and the others, as if to devour them whole.

Ye Yuanchen and his companions faced unprecedented pressure. Although their attacks could damage the Dark Night Demon Lord, the monster possessed extremely strong regenerative abilities, rapidly recovering from each injury. Moreover, the monster's attack range was vast, making it difficult for them to find effective opportunities to counterattack while dodging its attacks.

At a crucial moment in the battle, Ye Yuanchen suddenly recalled his experience exploring the Source of Darkness in the Spirit Realm. He realized that the rebirth of the Dark Night Demon Lord might be connected to the Source of Darkness. He decided to take the risk and reconnected his soul power with the primordial power of the Spirit Realm, attempting to channel this power into his attack on the Dark Night Demon Lord.

Mu Wanyue, Lu Zixuan, and Bai Youruo sensed Ye Yuanchen's intentions. They all connected their soul power with Ye Yuanchen, jointly gathering the power of the Spirit Realm's origin. Ye Yuanchen transformed this powerful force, which combined the soul power of everyone and the power of the Spirit Realm's origin, into a giant golden blade of light, and slashed down towards the dark monster body of the Dark Night Demon Lord.

In a blinding flash of light and a surge of intense energy, the Dark Lord's monstrous dark form was struck. This time, he suffered a fatal blow, his body beginning to dissipate. The Dark Lord let out a desperate roar as his soul began to crumble under the impact of this powerful force.

Finally, the Dark Night Demon Lord vanished completely, along with the dark aura. The border villages returned to peace, but Ye Yuanchen and the others knew this was only temporary. They had to delve deeper into the reasons for the Dark Night Demon Lord's rebirth and how to prevent similar dark forces from rising again to ensure world peace and tranquility.

After resolving the crisis in the border village, Ye Yuanchen and his companions began searching the world for clues related to the rebirth of the Dark Night Demon Lord. They discovered mysterious runes and formations within ancient ruins corrupted by dark forces, runes and formations that seemed connected to the Dark Night Demon Lord's rebirth ritual. They decided to delve into these ruins, uncover their secrets, and lay the foundation for completely eliminating the threat of dark forces.
