"Hmm?" Ye Feng was stunned. His Qi Sea was so vast, accumulated so much power, twice that of Huangfu Zhan, a mid-Middle Divine Realm expert. Ye Feng used this immense power to attack the bottleneck, yet it remained unmoved. Furrowing his brows, Ye Feng refused to give up and continued to assault his own bottleneck.
"Boom~~~" Immediately after, Ye Feng operated his True Essence again, using his accumulated strength, slammed into his bottleneck. His body emitted another dull sound, air currents surged.
"Hmm?" Ye Feng was somewhat surprised. Despite exerting even more effort on the second strike compared to the previous one, his bottleneck still showed no sign of movement or any indication of a breakthrough.
Clearly, Ye Feng was absolutely unwilling to give up so easily, continuing to assault his own bottleneck.
In the blink of an eye, three days passed, during which Ye Feng repeatedly attacked his bottleneck hundreds of times, yet it showed no signs of loosening.
