The Immortal Physician's Transmigration: Miraculous Rejuvenation

Ye Yuanchen and the others rushed back to the Three Realms without stopping. Along the way, the light emitted by the sacred artifact seemed to sense the impending crisis and shone even brighter. However, as they approached the Three Realms, a dense aura of darkness swept over them. Looking into the distance, they saw that the sky above the Three Realms was shrouded in a black haze, with eerie lights flashing intermittently in the darkness, as if the dark forces were having a wild party.

"The situation is worse than we imagined. The dark forces seem to have already ravaged the Three Realms on a large scale." Ye Yuanchen's expression was solemn, and his eyes revealed deep worry. He gripped the Spirit Void Holy Sword in his hand, increased his flying speed, and was anxious to arrive as soon as possible.

Looking at the dark sky, Mu Wanyue was filled with worry: "I wonder how the beings of the Three Realms are doing now. We must act as soon as possible." The Spirit Whip in her hand trembled slightly, as if it too was eager for the upcoming battle.

As Lu Zixuan flew, he took out various detection magic treasures from his storage magic treasure, trying to understand the specific situation in the Three Realms: "Judging from the detection results of these magic treasures, the distribution of dark power is extremely uneven. Some sects and holy sites in the cultivation world have been completely occupied by dark power, some spiritual veins in the spirit world have also been eroded by dark aura, and the mortal world has fallen into chaos, with war, plague and famine following one after another."

Bai Youruo played the Lingxu Lingyin Flute. The flute's sound was somewhat weak in the dark environment, but it still resolutely spread towards the Three Realms, trying to bring a glimmer of hope and courage to those creatures struggling in the darkness: "We cannot let the dark forces continue to run rampant. We must find the core of the dark forces as soon as possible and completely destroy them."

The moment they stepped into the Three Realms, the scene before them filled them with anguish. The once bustling towns of the cultivation world were now dilapidated, the streets permeated with the stench of death, littered with the corpses of cultivators and monsters transformed by the corrupting forces of darkness. Some sects' buildings had been destroyed by dark magic, leaving only ruins; their magical treasures and secret manuals had been looted by the forces of darkness. The once beautiful mountains were now barren, their spiritual plants devoured by the dark aura, their springs dried up, leaving only desolation.

The situation in the Spirit Realm was far from optimistic. A somber atmosphere permeated the cities of the Spirit Race; many of their people had lost their homes, weeping and struggling amidst the ruins. Dark clouds obscured the sky, preventing sunlight from penetrating and hindering the growth of spiritual plants. Some weaker Spirit Race members teetered on the brink of death due to lack of food and spiritual energy. The disruption of the spiritual veins also prevented Spirit Race cultivators from training properly, significantly weakening their abilities and leaving them powerless against the encroaching forces of darkness.

The mortal realm was a scene of utter devastation. Cities and villages were ravaged by war, and people fled in all directions, becoming homeless and displaced. Crops withered in the fields, livestock died, and famine spread. Plague ravaged the population, and the sick groaned in agony, with no one able to offer help. Dark forces also created many terrifying monsters in the mortal realm, which attacked villages and towns, slaughtering innocent people and plunging the mortal world into endless fear.

Seeing all this, Ye Yuanchen and the others were filled with anger and self-reproach. They knew they bore the heavy responsibility of saving the Three Realms and could not afford to be negligent in the slightest.

"We must first find the core of the dark power. Only by destroying the core can we completely resolve this crisis," Ye Yuanchen said calmly, suppressing his grief.

They explored the Three Realms, relying on the power of the sacred artifacts and their own senses to gradually approach the core area of ​​the dark power. Along the way, they encountered countless attacks from dark creatures, but they repelled them all. These dark creatures, nourished by the dark power, had become exceptionally powerful, and their attack methods had become more diverse and bizarre. Some dark creatures could spew black venom, which was extremely corrosive and would rapidly corrode the body once it came into contact with it; some dark creatures could unleash dark magic, distorting the surrounding space and plunging people into endless illusions; and still others were enormous and incredibly strong, wielding huge weapons and launching fierce attacks on Ye Yuanchen and his companions.

Faced with these powerful enemies, Ye Yuanchen and his companions cooperated, unleashing their respective ultimate techniques. Ye Yuanchen's Spirit Void Holy Sword, empowered by the sacred artifact, could slay large swarms of dark creatures with each strike. He unleashed an upgraded version of the "Spirit Realm Chaos Suppressing God Technique," making his swordplay even more ferocious and powerful, capable of instantly shattering the enemy's defenses. Mu Wanyue's Spirit Void Whip moved like a nimble dragon, weaving freely among the dark creatures. Wherever the whip's shadow, interwoven with pink and seven-colored light, dark creatures were whipped away. She also unleashed an enhanced version of the "Spirit Dance Illusion Whip Void Break," which, while attacking the enemy, infused their bodies with the purifying power of the sacred artifact, disintegrating their dark power from within. Lu Zixuan skillfully arranged an array during the battle, infusing the power of the sacred artifact into it to create a new "Spirit Void Sacred Array." This array not only trapped enemies but also continuously attacked and purified them. The spiritual energy arrows emitted from the array contained the powerful force of the sacred artifact, easily penetrating the bodies of the dark creatures and annihilating them. Bai Youruo played the Spirit Void Spirit Sound Flute, the sound transforming into tangible golden sound waves that surged towards the dark creatures like a raging tide. Wherever the sound waves reached, the dark aura melted away as quickly as ice and snow meeting the blazing sun. She perfectly fused her own soul power with the power of the sacred artifact, giving the flute sound the powerful ability to penetrate souls and dispel darkness, directly targeting the core of the dark creatures' souls, plunging them into chaos and pain, and rendering them unable to fight.

In their relentless battles, they gradually approached the heart of the dark forces—a colossal dark castle. This castle hovered above dark clouds, exuding a suffocating aura of darkness. Its walls were etched with various sinister runes and patterns, their eerie light shimmering as if recounting the dark forces' wicked history. A powerful dark shield surrounded the castle, crackling with black lightning that struck any creature that approached, instantly obliterating it.

"This is the lair of the dark forces. We must be careful." Ye Yuanchen gazed at the dark castle, his eyes revealing a firm resolve.

They cautiously observed the area around the castle, trying to find a way to break through the shield. After careful study, Lu Zixuan discovered that the runes on the shield would show a brief vulnerability every now and then, but this vulnerability would only last for a very short time, just a moment.

"We must seize this opportunity and launch a full-scale attack when the opening appears, breaking through the shield in one fell swoop," Lu Zixuan said.

Everyone nodded, adjusting their state to prepare for the crucial battle to come. Ye Yuanchen concentrated all the power of the sacred artifact into the Spirit Void Sacred Sword, causing it to shine brightly like a dazzling sun. Mu Wanyue gripped the Spirit Void Whip tightly, pink and seven-colored light flowing across its surface, her gaze focused and resolute. Lu Zixuan set up the "Spirit Void Sacred Array" beneath his feet, the spiritual energy lines within the array shimmering with the light of the sacred artifact, ready to be activated at the critical moment. Bai Youruo played the Spirit Void Spiritual Sound Flute, the rhythm of the music gradually quickening, golden sound waves swirling around her, brimming with power.

They waited silently for the shield to break through, each second feeling incredibly long. Finally, the runes on the shield flickered a few times, revealing a tiny opening.

"Now!" Ye Yuanchen shouted, charging towards the shield first. He unleashed the "Spirit Realm Holy Light Demon-Slaying Style," the Spirit Void Holy Sword transforming into a golden lightning bolt, piercing towards the shield's weakness.

Mu Wanyue, Lu Zixuan, and Bai Youruo launched their attacks simultaneously. Mu Wanyue's Spirit Whip, like a pink meteor, lashed out at the opening. Lu Zixuan manipulated the "Spirit Void Sacred Array," unleashing a massive arrow of spiritual energy, imbued with the powerful force of a sacred artifact, which shot towards the opening. Bai Youruo played her Spirit Flute, the notes transforming into a powerful golden sound wave that surged towards the opening.

Four powerful forces struck the shield's weaknesses simultaneously, unleashing a deafening roar. Under the impact of these powerful forces, cracks appeared in the dark shield before it shattered completely.

As the shield shattered, a swarm of dark creatures and dark mages poured out of the Dark Castle. They launched a frenzied attack on Ye Yuanchen and his companions, attempting to prevent them from entering the castle.

Undeterred, Ye Yuanchen and his companions engaged in fierce close combat with their enemies. Ye Yuanchen's Spirit Void Holy Sword lashed out among the dark creatures, each strike claiming the lives of countless foes. Mu Wanyue's Spirit Void Whip danced in the air, lashing away any approaching enemies. Lu Zixuan constantly adjusted the formation during the battle, using its power to trap the enemy before launching his own attacks. Bai Youruo played her Spirit Sound Flute, the music disrupting the enemy's movements and rendering their attacks chaotic and disordered.

In the fierce battle, Ye Yuanchen and his companions gradually ventured deeper into the castle. They discovered that the dark power within the castle was even more concentrated, and every step they took was fraught with immense pressure. However, their belief remained unwavering: they were determined to find the source of the dark power, completely destroy it, and save the Three Realms from their dire straits.
