The Immortal Physician's Transmigration: Miraculous Rejuvenation

As that powerful, malevolent aura descended, a colossal figure gradually became clear in the void—the ruler of the Void Shadows. Its form was as imposing as a mountain, its entire body covered in a layer of black armor, the armor shimmering with eerie blood-red runes and radiating an intense aura of darkness. Its head resembled a massive black hole, from which two beams of blood-red light shot forth, seemingly capable of discerning the weaknesses of all things in the world.

"Is this the ruler of the Void Shadows? It looks extremely powerful." Ye Yuanchen's expression was solemn. Holding the Spirit Void Holy Sword, he raised his spiritual power to the limit and watched the behemoth in front of him warily.

Mu Wanyue tightened her grip on the Spirit Void Whip, a resolute glint in her eyes. "No matter how powerful it is, we must defeat it today, or the Three Realms will never know peace."

Lu Zixuan quickly set up a "Spirit Void Chaos Demon-Slaying Array" around everyone, combining defense and offense. This was created by him based on his previous research on the shadows of the void and the characteristics of the Spirit Void Sacred Artifact. After the array was set up, Spirit Void runes flickered within it, forming a powerful spiritual energy shield, while the offensive runes within the array were also poised to be unleashed.

Bai Youruo played the Lingxu Lingyin Flute, and the flute's notes transformed into countless sonic blades that flew towards the Shadow Overlord. As these sonic blades approached the Shadow Overlord, although they were blocked by the dark aura emanating from it, they successfully attracted some of its attention.

The Shadow Overlord unleashed a deafening roar, the sound waves materializing into a black storm that swept towards Ye Yuanchen and the others. Wherever the storm passed, space was torn apart, and dark energy spread rampantly.

Ye Yuanchen unleashed the fusion technique of the "Spirit Realm Chaos Suppressing God Technique" and the Spirit Void Holy Sword, slashing fiercely at the black storm. A golden blade of spiritual energy collided with the storm, producing a deafening roar. Light and darkness intertwined, temporarily offsetting some of the storm's power.

Mu Wanyue then wielded the Spirit Whip, unleashing the immortal technique "Spirit Dance Illusion Whip Void Break." The whip transformed into a pink streak of light, weaving through the gaps in the black storm and lashing towards the Shadow Lord. The whip struck the Shadow Lord's armor, failing to inflict any substantial damage, but it did make the Shadow Lord feel a sense of threat.

Lu Zixuan continuously adjusted the formation's power, infusing more spiritual energy into the attack runes. Spiritual energy arrows rained down on the Shadow Overlord, their penetrating power amplified by the Spirit Void Sacred Artifact, striking the Shadow Overlord's body one after another. However, the Shadow Overlord's body seemed to be protected by a powerful energy shield; the arrows only caused ripples upon impact, failing to penetrate it.

Bai Youruo's flute playing grew increasingly high-pitched and passionate as she unleashed the strongest sonic attack of her "Spiritual Chaos Demon-Slaying Melody." The sonic blades within the flute music continuously sliced ​​through the dark aura surrounding the Shadow Lord, attempting to weaken its defensive power.

Under the onslaught of the group, the Shadow Overlord seemed to be enraged. It suddenly raised a massive arm, and the black armor on the arm began to transform, turning into a huge dark energy cannon. Intense dark energy gathered at the muzzle, flashing with light, foreshadowing an impending powerful attack.

"Everyone be careful, quickly hide in the formation!" Ye Yuanchen shouted, knowing full well that the power of this attack was extraordinary.

Everyone quickly took cover in the "Spirit Void Chaos Demon Extermination Array" set up by Lu Zixuan. The array's spiritual energy shield instantly thickened, and they did their best to resist the impending attack.

The Dark Energy Cannon fired by the Shadow Overlord unleashed a black beam of energy that shot towards the formation where Ye Yuanchen and the others were located, like a black meteor. The energy beam collided with the formation's spiritual energy shield, producing a deafening explosion. The entire formation trembled violently, the spiritual energy runes flickered erratically, and some runes even began to shatter under the immense impact.

"Hold on!" Lu Zixuan shouted, pouring all his soul power and spiritual energy into the formation in an attempt to repair the damaged runes and maintain its stability.

Ye Yuanchen, Mu Wanyue, and Bai Youruo also transferred their power to Lu Zixuan, working together to support the formation. With everyone's concerted efforts, the formation finally stabilized, but it was already teetering on the brink of collapse.

“This won’t do. We must find its weakness in order to have a chance to defeat it,” Ye Yuanchen said, a hint of anxiety in his eyes.

In the midst of the fierce battle, Ye Yuanchen carefully observed the Shadow Overlord's every move. He discovered that whenever the Shadow Overlord launched an attack, a faint light would flicker within the black hole on its head, seemingly the core convergence point of its energy.

"Everyone, focus your attacks on the black hole in its head; that might be its weak point!" Ye Yuanchen shouted.

Upon hearing this, everyone turned their attacks towards the black hole in the head of the Shadow Overlord. Ye Yuanchen unleashed the combined power of the "Spirit Realm Holy Healer's Demon-Slaying Divine Technique" and the Spirit Void Holy Sword, unleashing a massive blade of light containing the power of life, the power of light, and the power of soul purification towards the head of the Shadow Overlord.

Mu Wanyue wielded the Spirit Void Whip, the tip of which split into countless tiny branches, each containing powerful spiritual energy, which coiled around the head of the Shadow Overlord in an attempt to disrupt its energy convergence.

Lu Zixuan manipulated the formation within the array, concentrating all the attack power at one point and firing a powerful beam of spiritual energy towards the head of the Shadow Overlord.

Bai Youruo played the Lingxu Lingyin Flute, and the flute music transformed into a powerful soul impact force that surged toward the black hole at the head of the Shadow Overlord, attempting to disrupt its soul core.

Under the combined attack of everyone, the black hole at the head of the Shadow Overlord was somewhat impacted. The light within the black hole flickered erratically, and its attacks became slower.

"It works! Let's continue the attack!" Ye Yuanchen shouted excitedly.

However, the Shadow Overlord was not so easily defeated. Sensing the threat to the black hole in its head, it immediately changed its attack method. It plunged its hands into the void and then pulled sharply, creating a massive spatial rift before everyone. Countless shadow creatures of the void surged out of the rift, swarming towards Ye Yuanchen and the others in greater numbers and with greater strength than before.

"Damn it! It's trying to drain our strength," Mu Wanyue said, frowning.

Ye Yuanchen and the others were forced to divert their attention once again to deal with the endless stream of Void Shadow creatures. However, they knew in their hearts that they could not be held back by these creatures. They had to find an opportunity as soon as possible to launch a fatal blow against the Shadow Overlord's weakness. Otherwise, the battle would fall into an endless stalemate, and the Three Realms would face annihilation.
