A Spiral Sphere of Yin Power and a Spiral Sphere of Yang Power.
After experimenting for some time, Qin Shaofeng discovered that if he separated the Yin-Yang Power and hurled them out to collide in an attack, they could unleash even greater force.
Although Yin-Yang Power could merge, Yin Power and Yang Power also possessed an extremely intense mutual repulsion.
Otherwise, Qin Shaofeng's cultivation in the World King Realm would not have involved raising all six thousand layers of his domains, one by one, to saturation and perfection.
Nor would his six thousand layers of domains have begun showing signs of Yin-Yang fusion after he possessed three thousand saturated and perfected domains.
When Yin-Yang Power merged, it could unleash greater strength. Likewise, when it repelled itself, it could erupt with terrifying power.
Naturally, the Blade Demon Clan's ancestor knew nothing of this.
Thus, when he faced the two Spiral Spheres—one Yin and one Yang—howling toward him, he paid them little heed.
In his eyes, the power of those two Spiral Spheres was not enough to threaten him.
Yet the instant the Black Blade in his hand slashed one of the Spiral Spheres apart, his expression changed drastically.
Under Qin Shaofeng's control, the two Spiral Spheres had blasted toward the Blade Demon Clan's ancestor one after the other, though the distance between them was not particularly great.
The moment the Blade Demon Clan's ancestor destroyed the first Spiral Sphere, the second one appeared.
And when the first Spiral Sphere was cut apart, it exploded with a boom.
At that moment, the second Spiral Sphere appeared. Then Yin-Yang Power emerged, and under Qin Shaofeng's deliberate reinforcement, the Yin and Yang forces instantly began repelling each other madly.
Then, an incomparably terrifying force swiftly brewed, followed by an even more dreadful explosion.
Boom!
