One Spiraling Sphere of Yin Power and one Spiraling Sphere of Yang Power.
After experimenting for some time, Qin Shaofeng had discovered that if he separated the Yin Yang Power and threw the two forces out to collide, they could unleash even greater power.
Although Yin Yang Power could be fused together, the two forces also repelled each other intensely.
Otherwise, Qin Shaofeng's cultivation in the Realm King Realm wouldn't have involved raising all six thousand layers of his domain one by one to saturation and perfection.
Nor would his six thousand layers of domain inside his body have begun to fuse Yin and Yang after he had three thousand saturated and perfected layers.
The fusion of Yin Yang Power could unleash even greater strength, and its repulsion could likewise unleash terrifying power.
The Blade Demon Clan ancestor naturally knew nothing about this.
So when he faced two Spiraling Spheres hurtling toward him, one Yin and one Yang, he didn't pay them much heed.
In his eyes, the two Spiraling Spheres weren't powerful enough to threaten him.
But the moment the Black Blade in his hand cleaved one of the Spiraling Spheres apart, his expression changed.
Qin Shaofeng had sent the two Spiraling Spheres crashing toward the Blade Demon Clan ancestor one after the other. The distance between them, however, wasn't very great.
As the Blade Demon Clan ancestor cleaved apart the first Spiraling Sphere, the second one appeared behind it.
And the moment the first Spiraling Sphere was cleaved apart, it exploded with a boom.
At that moment, the second Spiraling Sphere appeared, and Yin Yang Power surged forth. With Qin Shaofeng deliberately bolstering it, the Yin and Yang forces began to repel each other violently.
Then a terrifying force instantly gathered, setting off an even more fearsome explosion.
