Chapter 588: Immortal-Demon Duel, Mutual Destruction

Accompanied by the sound of his shrill incantations, the entire Blood Sacrifice Array began to undergo a terrifying transformation. The black vortex at the center of the array suddenly ceased its rotation, replaced by a profound silence, as if even time had stopped flowing at this very moment.

Immediately following, an aura a thousand times more terrifying than all previous evils combined began to rise slowly from the depths of the array. This aura was ancient and evil, filled with hatred for life and contempt for order; merely sensing a trace of it made everyone present feel fear from the depths of their souls.

"Th-this... what is this thing?" Taixuan Laozu asked with a trembling voice; he had cultivated for hundreds of years and had never felt such a terrifying pressure.

Xinghe Laozu's expression became unprecedentedly grave: "The will of the Hun Dun Demon God... it is finally about to awaken!"

The sky began to undergo violent changes; the originally blood-red clouds instantly turned a deep black, as if countless hideous faces were rolling and roaring within the clouds. The earth began to tremble violently, and countless bottomless cracks appeared on the surface of Qinglong Peak; what surged from the cracks was not magma, but pure Hun Dun Power.

Even more terrifying was that space itself began to distort. Around the array, originally straight lines became curved, originally clear scenes became blurred, and even the flow of time became unstable.

"Hehehe... a thousand years... a full thousand years..." A malicious voice began to resound in everyone's hearts; this voice was like a whisper from the depths of hell, and every word made one's heart and gallbladder split, "Finally, someone has awakened this god... very good... very good..."

A massive Yinying began to appear in the center of the array. This Yinying had no fixed shape; at times it looked like a mass of black mist, at times like giant tentacles, and at other times like a hideous demonic face. It constantly changed its form, as if it contained all the possibilities of evil in the world.

"Hun Dun Demon God!" Xiao Yuan looked at the terrifying entity taking shape, a tremendous pressure surging in her heart. Even though her Primordial World-Purifying Technique had reached Great Completion, she still felt inadequate when facing an enemy of this caliber.

The awakening of the Demon God caused the situation of the entire battlefield to reverse instantly. Those Demon soldiers who had originally been suppressed by Xiao Yuan's divine light regained their strength, becoming even more powerful than before. The Demon General Baloke laughed wildly and said: "Hahaha! The great Hun Dun Demon God has awakened! You lowly humans, prepare to accept judgment!"

"Xiao Yuan, this enemy is too powerful; we must find a way!" Lin Xuan gripped Xiao Yuan's hand tightly, feeling the trembling of her body. He knew that even the power of the Primordial World-Purifying Technique appeared insignificant when facing a true Hun Dun Demon God.

Suddenly, Lin Xuan thought of a possibility: "Xiao Yuan, do you remember the core philosophy of the Taiji Evolution Technique? Yin and Yang complement each other, and hardness and softness assist one another. Your Primordial World-Purifying Technique represents ultimate purity, while my Taiji Evolution Technique contains the transformation of Yin and Yang. If we join forces, perhaps we can create an even more powerful force!"

Xiao Yuan's eyes lit up: "You mean... the Union of Yin and Yang?"

"Exactly!" Lin Xuan nodded firmly, "Although we have never tried it, there is no other choice now. Are you willing to trust me?"

"Of course!" Xiao Yuan nodded without hesitation, "From the moment we met until now, I have always trusted you!"

The two looked into each other's eyes, both able to see the firmness and trust in the other's gaze. They held each other's hands tightly and began to circulate their respective techniques simultaneously.

The pure power of the Primordial World-Purifying Technique and the Yin-Yang Qi of the Taiji Evolution Technique began to flow between the two; these two distinct powers produced a wondrous chemical reaction the moment they touched. The pure platinum light and the profound Taiji Rune merged, gradually forming a perfect Taiji Pattern.

"Th-this... what is this?" Xinghe Laozu saw the changes occurring in Lin Xuan and Xiao Yuan, a flash of shock appearing in his eyes, "The Union of Yin and Yang... could it be that they are going to execute the legendary Taiji Yin-Yang Great Perfection?"

The Taiji Pattern rotated slowly behind the two, emitting a light that was both sacred and profound. This light was different from Xiao Yuan's previous divine light; it not only contained the power to purify evil but also embodied the ultimate mysteries of creation and destruction, life and death, and Yin and Yang.

"Impossible! How could mere humans master such a profound method!" The Hun Dun Demon God felt the threat of this power and let out an angry roar.

However, the combined attack of Lin Xuan and Xiao Yuan continued to strengthen. The consciousnesses of the two began to gradually merge; they could feel each other's heartbeats, feel each other's thoughts, and even feel the light in the depths of each other's souls.

Just at this moment, Xinghe Laozu also made a decision. He took a deep breath and began to burn his thousand years of cultivation: "Since the juniors have such resolve, then this old man cannot fall behind! Ancient Sealing Technique—Ten Thousand Stars Return to Origin!"

Countless starlight descended from the sky, forming a massive sealing Dharma Array under the control of Xinghe Laozu. This array used stars as nodes and starlight as links, emitting a power capable of sealing all evil.

"This old man is willing to pay the price of a thousand years of cultivation to seal this demon once again!" Xinghe Laozu's body began to become illusory, clearly overdrawing his own life force.

Facing the siege of three powerful forces, the Hun Dun Demon God finally felt the threat. It waved its tentacles frantically, attempting to eliminate these threats before it fully awakened.

However, at this critical moment, bursts of Immortal music suddenly came from above the Nine Heavens. A brilliant Immortal light descended from the clouds, shining directly onto the center of the battlefield.

"The Human Realm faces a great catastrophe; how could the Immortal Realm sit idly by?" A majestic and compassionate voice resounded through heaven and earth, "Hun Dun Demon God, your era has ended!"

The moment the Immortal light descended, the entire battlefield was enveloped by sacred power. This was direct intervention from the Immortal Realm, representing the fact that the highest-level power in the Three Realms had officially participated in this decisive battle.

Seeing the Immortal light descend, the Hun Dun Demon God let out a desperate and angry howl: "Immortal Realm! It is the Immortal Realm again! Why must you always obstruct this god's revenge!"

Within the brilliant Immortal light, a woman dressed in white Immortal robes descended slowly. Her appearance was stunningly beautiful, and she was surrounded by white lotus flowers, each petal emitting pure Immortal spiritual energy. This was the Immortal specifically responsible for purifying evil in the Immortal Realm—Cihang Xianzi.

"Amitabha, how benevolent, how benevolent." Cihang Xianzi chanted the Buddha Sect name softly; her voice was as pleasant as heavenly music, yet it contained supreme majesty, "Hun Dun Demon God, your evil has already threatened the balance of the Three Realms; today, this humble practitioner shall act on behalf of the heavens to purify your evil existence."

The appearance of Cihang Xianzi made Xiao Yuan feel an unprecedented resonance.
