The Immortal Physician's Transmigration: Miraculous Rejuvenation

After the remnant soul of the Chaos Demon God was sealed in the Spirit Void Sealing Tower, the space inside the crystal ball temporarily returned to calm, but Ye Yuanchen and the others knew that the crisis was not over. The crystal ball still emitted a ghostly blue light, the spiritual energy patterns inside were chaotic, and the powerful, corrupted energy was still surging faintly, like a time bomb that could explode again at any moment.

"We must purify this crystal ball as soon as possible, otherwise the consequences will be unimaginable once the remnant soul of the Chaos Demon God breaks through the seal." Ye Yuanchen said solemnly, his eyes revealing a firm determination. He gripped the Spirit Void Holy Sword tightly in his hand, constantly vigilant for any possible changes around him.

Mu Wanyue nodded gently, the Spirit Whip in her hand trembling slightly, as if responding to the unstable spiritual energy within the crystal ball. "But the power within this crystal ball is so strong and complex, how can we purify it? Although we temporarily stabilized it using the power of the Five Elements, it is clearly not enough."

Lu Zixuan lowered his head and pondered for a moment, then raised his head and said, "I once saw an ancient purification method in ancient books. It requires the use of pure spiritual energy from heaven and earth to guide it into a crystal ball in order to purify the evil power within. However, this method is extremely dangerous and requires a very high level of control over spiritual energy from the practitioner."

Bai Youruo played a soothing, ethereal flute melody, trying to ease everyone's tension. "No matter how dangerous it is, we must try. For the safety of the Three Realms, we cannot back down."

Having reached a consensus, the group began preparations for the purification ritual. Ye Yuanchen used the Spirit Void Holy Sword to draw complex runes around the crystal ball. These runes connected to form a massive spiritual energy guiding array, designed to attract pure spiritual energy from heaven and earth. Mu Wanyue assisted Ye Yuanchen, using the Spirit Void Whip to smooth the lines of spiritual energy in the array, ensuring unobstructed transmission. Lu Zixuan placed special spirit crystals at key points in the array, enhancing its ability to gather and guide spiritual energy. He also prepared spare sealing artifacts in case the remnant soul of the Chaos Demon God broke through the seal again. Bai Youruo played the Spirit Sound Flute, the music transforming into a gentle force that permeated the entire space, calming the chaotic spiritual energy and creating a relatively stable environment for the purification ceremony.

As the array was activated, the surrounding space began to change. Brilliant beams of light appeared in the sky, converging on the crystal ball like flowing ribbons. However, during this convergence, the corrupted power within the crystal ball seemed to be stimulated and began to violently resist. The remnant soul of the Chaos Demon God also continuously attacked the seal within the sealing tower, attempting to prevent the purification process.

"Everyone, hold on! Increase your spiritual power output, don't let it disrupt the purification ritual!" Ye Yuanchen shouted loudly. He poured all his spiritual power into the formation without reservation, his forehead covered with sweat, but his eyes became more and more determined.

Mu Wanyue, Lu Zixuan, and Bai Youruo also gritted their teeth and channeled their spiritual power to support Ye Yuanchen. Mu Wanyue's Spirit Whip emitted a dazzling pink light as she continuously transmitted her spiritual power into the formation. Lu Zixuan manipulated the various nodes of the formation, constantly adjusting the flow and intensity of spiritual power to ensure its stable operation. Bai Youruo's flute playing grew increasingly high-pitched and passionate as she infused her soul power into the music, enhancing its calming and guiding effect on the spiritual power.

With everyone's concerted efforts, pure spiritual energy finally began to slowly flow into the crystal ball. At first, the black aura within the crystal ball collided and intertwined with the pure spiritual energy, producing a hissing sound, and the entire crystal ball trembled violently, as if it might shatter at any moment. However, as the pure spiritual energy continued to flow in, the black aura was gradually suppressed, and the trembling of the crystal ball gradually subsided.

However, just as the purification was about to be completed, an unexpected event occurred. The remnant soul of the Chaos Demon God suddenly erupted with a powerful force, breaking through part of the seal of the Spirit Void Sealing Tower. A black energy pillar surged out from within the sealing tower, rushing towards Ye Yuanchen and the others who were performing the purification ritual.

"Watch out!" Ye Yuanchen exclaimed. He quickly used the "Spirit Realm Chaos Suppressing God Technique" to gather spiritual power in front of him, forming a shield in an attempt to block the impact of the black energy pillar.

Mu Wanyue, Lu Zixuan, and Bai Youruo also unleashed their respective special skills to jointly resist the sudden attack. Mu Wanyue wielded the Spirit Void Whip, using the immortal technique "Spirit Dance Illusion Whip Void Break," the whip transforming into a pink light that intertwined with the black energy pillar, attempting to weaken its power. Lu Zixuan quickly set up a defensive sub-array within the formation, guiding some of the black energy pillar's power underground to reduce the pressure of the direct impact. Bai Youruo played the Spirit Void Sound Flute, the flute's notes transforming into sonic blades that cut through the surface of the black energy pillar, dispersing its energy.

Despite everyone's best efforts to resist, the power of the black energy pillar was simply too great, and they gradually found themselves in a predicament. Ye Yuanchen's shield began to crack, Mu Wanyue's spirit whip was also struggling to hold on, Lu Zixuan's formation was on the verge of collapse under the powerful impact, and Bai Youruo's hands, which were playing the flute, began to tremble.

"Have we failed like this?" A sense of despair welled up in Mu Wanyue's heart, but her eyes still revealed an indomitable light.

At this critical moment, Ye Yuanchen suddenly remembered the mysterious power within him—the power of chaos from the spirit realm. He had obtained this power by chance, and had rarely used it because it was too powerful and difficult to control. But now, in order to save the Three Realms, he decided to risk it and give it a try.

Ye Yuanchen closed his eyes, concentrated his mind, and began to guide the chaotic power of the spiritual realm within his body. As he guided it, a powerful and mysterious force surged forth from his body, merging with his spiritual energy. A layer of golden light emanated from his body, containing boundless chaotic energy.

"Everyone, transfer your power to me!" Ye Yuanchen shouted.

Mu Wanyue, Lu Zixuan, and Bai Youruo unhesitatingly transferred their power to Ye Yuanchen. With the combined power of the group, Ye Yuanchen's strength reached an unprecedented level. He suddenly opened his eyes, which flashed with golden chaotic light, and then fiercely swung his sword at the black energy pillar.

This sword strike contained the chaotic power of the spirit realm, the spiritual power of everyone present, and Ye Yuanchen's unwavering belief; its power was earth-shattering. A massive golden blade of light flew out from the Spirit Void Holy Sword, colliding with the black energy pillar. With a deafening roar, the black energy pillar was cleaved in two by the blade of light, then gradually dissipated into the air.

Having successfully averted this crisis, Ye Yuanchen and the others dared not slacken their efforts and continued to purify the crystal ball with all their might. With the continuous infusion of pure spiritual energy, the black aura within the crystal ball was finally completely purified, the eerie blue light became clear and bright, and the disordered spiritual energy patterns returned to normal order.

As the crystal ball completed its purification, the entire ruins began to tremble violently. The runes on the walls flashed with dazzling light, the cracks in the ground gradually healed, and the originally dark and damp environment became bright and refreshing.

"We succeeded!" Ye Yuanchen and the others cheered excitedly. They knew that the Three Realms had once again escaped a catastrophic disaster.

Before leaving the ruins, Ye Yuanchen and the others carefully placed the crystal ball, setting up powerful seals and defensive formations to ensure its power would not be used by evil forces again. Then, weary but relieved, they embarked on their return journey, ready to bring this good news back to the Three Realms and share this hard-won peace and tranquility with all living beings.
