An Xingning was now using a secret technique that forcefully enhanced his strength in an instant.
This secret technique could provide a temporary boost, but it came with great harm to the body, causing severe internal injury and leaving one weak and powerless for months after each use.
An Xingning's previous loss of strength and increasingly severe internal injuries, even to the point of life-threatening, were because of his excessive use of this secret technique years ago.
At this point, he could no longer afford to care about the consequences. If he could defeat Zhang Tao, even if he sustained a massive drain on his Inner Qi, it wouldn't matter; after all, there was no chance of him advancing further in his cultivation in this lifetime.
With a muffled roar, An Xingning raised his hand and struck.
Though this time he was slightly slower than before, his fist brought a whirlwind around him, like Tai Mountain collapsing. The power of the blow was unimaginable.
