The Immortal Physician's Transmigration: Miraculous Rejuvenation

Ye Yuanchen stared intently at the gradually clearing dark figure within the magic array, sensing a destructive dark power surging forth from it. The dark figure was surrounded by black mist, within which countless twisted faces struggled and howled, like vengeful spirits from hell.

Ye Yuanchen knew that there was no time to hesitate. He raised the Spirit Void Holy Sword high and released his spiritual power and the power of the sacred artifact without reservation. "Spirit Realm Chaos Suppressing God Technique!" Ye Yuanchen shouted, and a dazzling golden sword aura, carrying immense purifying power, shot towards the dark figure like a golden meteor.

The sword energy struck the dark figure, unleashing a burst of intense light. The dark figure let out a shrill roar, and the dark mist around it instantly surged and churned. However, this attack did not inflict fatal damage on the dark figure. It quickly regained its footing, its blood-red eyes glaring fiercely at Ye Yuanchen.

The dark figure swung its arm, formed from dark power, and a black energy wave swept towards Ye Yuanchen. Ye Yuanchen quickly used his movement technique to dodge, but the energy wave grazed his body and struck the cave wall, instantly corroding a huge hole in it.

Taking advantage of a lull in the dark figure's attack, Ye Yuanchen launched another assault. His movements were lightning-fast, weaving through the cave, unleashing golden sword energy from various directions towards the dark figure. Although powerful, the dark figure was overwhelmed by Ye Yuanchen's relentless and fierce attacks, leaving it momentarily unable to defend itself.

Meanwhile, before the mysterious ruins of the spirit realm, Bai Youruo was straining to decipher the runes on the gate. Fine beads of sweat covered her forehead, but her eyes remained incredibly focused. After much effort, Bai Youruo finally found the way to break the runes. She channeled her spiritual power into the runes in a specific order, and the gate to the ruins slowly opened, releasing an ancient and mysterious aura.

Bai Youruo took a deep breath, gripped the Spirit Void Flute tightly, and cautiously stepped into the ruins. The interior was dimly lit, with strange lights shimmering on the walls. Bai Youruo followed the passage, discovering that the walls on both sides were covered with various ancient patterns and characters. These patterns seemed to tell an ancient story, about a dark catastrophe that once struck the spirit realm, and how a group of valiant spirits sealed away the dark forces.

Bai Youruo continued deeper into the ruins, and suddenly, a huge stone chamber appeared ahead. In the center of the chamber was a stone platform, on which rested a black crystal that emitted a ghostly light. Bai Youruo approached the platform and examined the crystal closely, discovering that it was extremely similar to the black crystal she had found in the Spirit Valley before, but the dark power it contained was far stronger.

Just as Bai Youruo was about to further study the crystal, a low roar suddenly echoed in the stone chamber. A gigantic dark beast slowly emerged from the darkness, its body resembling a small mountain, covered in sharp bone spikes, and its eyes gleaming with an eerie green light.

The dark beast opened its blood-red maw and roared at Bai Youruo, unleashing a powerful surge of dark spiritual energy that spread outwards. Bai Youruo swiftly played the Spirit Void Flute, its notes transforming into golden sound waves that countered the surge of dark spiritual energy.

"I cannot back down. There must be an important secret of the dark forces hidden here." Bai Youruo was determined as she played her flute and searched for the weakness of the dark beast.

In the frigid depths of the Spirit Realm, Lu Zixuan trudged onward. Here, the land was covered in ice and snow, the wind howling, each gust feeling like a sharp blade cutting into his face. Lu Zixuan circulated his spiritual energy, forming a shield to resist the biting cold.

According to ancient records, the "Spirit Heart Grass" grows in an ice cave in an extremely cold region. Lu Zixuan searched for traces of the ice cave amidst the vast expanse of ice and snow. Suddenly, he heard a deep roar, and a huge ice bear leaped out of the snowdrift, blocking his path.

The ice bear was enormous, radiating a chilling aura. Its eyes gleamed with ferocity as it opened its gaping maw at Lu Zixuan. Lu Zixuan knew that this ice bear was the guardian beast of the "Spirit Heart Grass," and that he had to defeat it to obtain it.

Lu Zixuan quickly set up a spiritual energy array, from which beams of spiritual energy shot out towards the ice bear. The ice bear swung its massive paws, scattering the beams of spiritual energy, and then charged towards Lu Zixuan.

Lu Zixuan skillfully dodged the ice bear's attacks while constantly searching for its weaknesses. He discovered that the ice bear's abdomen was relatively weak, so he concentrated his efforts on attacking the bear's belly.

Inside a cave in the abandoned mine, Ye Yuanchen's battle with the dark figure reached its climax. The dark figure's power seemed to be constantly increasing, while Ye Yuanchen's attacks were causing it less and less damage. Ye Yuanchen knew in his heart that if this continued, he would eventually be defeated by the dark figure.

"Is there really no way out?" Ye Yuanchen was extremely anxious. Just then, he suddenly remembered that he had used the power of the "Spirit Phoenix Guardian Pendant" when fighting against the dark forces. "Perhaps I can use its power again." With a thought, Ye Yuanchen immediately activated the power of the "Spirit Phoenix Guardian Pendant".

A golden light emanated from Ye Yuanchen, within which the faint phantom of a phoenix appeared. Using the power of the "Spirit Phoenix Guardian Pendant," Ye Yuanchen unleashed an even more powerful attack. "Spirit Realm Chaos Suppressing God Technique – Phoenix Dance of the Nine Heavens!" Ye Yuanchen roared, unleashing a golden sword aura imbued with the power of the phoenix towards the dark figure.

The dark figure sensed a tremendous threat and tried to dodge, but the sword energy followed relentlessly. The sword energy struck the dark figure, which let out a painful roar, and the dark mist surrounding it began to dissipate.

Within the mysterious ruins, Bai Youruo's battle with the dark beast reached a crucial moment. Bai Youruo discovered that the dark beast was extremely sensitive to sound, so she played an even sharper flute melody to disrupt its movements. The dark beast's movements became sluggish under the interference of the flute music.

Bai Youruo seized the opportunity and channeled her spiritual power into the Spirit Void Sound Flute. A powerful golden sound wave shot out from the flute, striking the dark beast in the head. The dark beast let out a miserable cry and collapsed to the ground.

Taking advantage of the moment, Bai Youruo walked to the stone platform and picked up the black crystal. The instant she picked it up, a surge of dark power erupted from it, attempting to invade her body. Bai Youruo quickly circulated her spiritual energy to resist, while simultaneously examining the crystal closely, discovering that it seemed to contain the outline of a map.

In the frigid realm of the spirit world, after a fierce battle, Lu Zixuan finally found the ice bear's weakness. He unleashed a spiritual spell, successfully striking the ice bear in the abdomen. The ice bear roared in anger and collapsed to the ground.

Lu Zixuan, disregarding the need for rest, continued his search for the ice cave. Finally, beneath a steep ice wall, he discovered a hidden ice cave. Lu Zixuan entered the cave, where a strange light permeated the air. Deep within the cave, he saw a celestial herb emitting a pale purple glow—the very "Spirit Heart Herb" he had been searching for.

Will Ye Yuanchen be able to completely defeat the dark figure? What secrets does the map outline Bai Youruo discovered in the black crystal hold? Will Lu Zixuan be able to return in time with the "Spirit Heart Grass" and break the "Heart-Eating Curse"? Everything is full of unknowns. The battle for Ye Yuanchen and the others to protect the Three Realms continues, and they will face even more severe tests.
