Everyone revealed looks of shock. The Yin-Yang Aurora Sword was Yin-Yang Ancestor's famed supreme treasure.
The sword's core was a piece of extraterrestrial iron. Yin-Yang Ancestor had obtained it by chance, forged it into a sword embryo, then gathered the auroras of Sky-Pillar Immortal Domain's northern and southern poles and refined them into the blade.
It was said that once this sword had been forged, not only was its edge unmatched beneath heaven, but when activated, it could unleash Yin-Yang aurora power capable of cleaving all things apart. It was an absolute masterpiece even among top-grade immortal treasures.
At that moment, the Yin-Yang Aurora Sword suddenly flared. In an instant, it released resplendent Yin-Yang auroras and cleaved straight toward the crowd, cutting the old monk cleanly in two at the waist in a single exchange.
Clang—
At the same time, Chen Nianzhi's Heavenly Separation Twin-Sword Fusion finally slew Immortal Qingshu.
He turned back and saw that the old monk's fate was unknown. Without delay, he sent the Heavenly Separation Twin Swords streaking forth as rainbows, slashing at Yin-Yang Ancestor.
"Hmph, a mayfly trying to shake a tree."
Facing Chen Nianzhi's Heavenly Separation Twin Swords, Yin-Yang Ancestor's expression remained as calm as ever.
Yin-Yang energies intertwined behind him, while the Yin-Yang Two-Poles Pearls transformed into a circular Yin-Yang polar shield around his body. He feared not the attacks of the Heavenly Separation Twin Swords in the slightest.
After blocking the attacks of the group, Yin-Yang Ancestor swept his gaze around, sizing up the three of them in a single thought.
Not only was Yin-Yang Ancestor astonishingly powerful, his combat experience was exceptionally seasoned. In an instant, he had made his decision.
He activated the Yin-Yang Aurora Sword once more, turning it into a dazzling immortal radiance that slashed toward Flower Fairy.
