Lu Yao's spiritual heart had been badly damaged multiple times, which would have normally dissipated several times over, yet he continued to bounce back with vigor.
Xu Fu's smile had faded from the corner of his mouth as he subtly moved his hand behind his back to hide his trembling fingers.
After all, he wasn't at his prime, and the ten "Primordial Magnetic Divine Thunders" had taken a significant toll on him.
At the same time, Xu Fu was puzzled—by a rough estimate, his opponent must have exhausted over a hundred million units of prayer power.
The abundance could be explained, but since prayer power was toxic, repeatedly calling upon such a vast amount should have driven the person mad!
Yet Lu Yao was far from insane. Instead, he taunted, "Didn't you have your meal? Keep it coming."
Xu Fu could never have imagined the existence of "Yan Huang prayer power," a type of spiritual power with no side effects.
