Once the Demon Emperor undergoes demonization, empowered by the strength of the ancestral Heavenly Demon, his physical form becomes incredibly resilient.
Even Chu Fengmian's Sword Edge cannot pierce the Demon Emperor's body.
However, this is only when the Demon Emperor is focusing all his efforts on defense.
As soon as he shows a flaw, his body will no longer possess such strength, and that's Chu Fengmian's chance to strike him down.
Right now, Chu Fengmian intentionally unleashed the Pure Yang Heavenly Fire precisely to force the Demon Emperor to reveal a flaw.
As he retreats, it presents the perfect opportunity for Chu Fengmian.
"Sword Break!"
Behind the Pure Yang Heavenly Fire, Chu Fengmian's Sword Qi suddenly burst forth, a colossal Sword Qi slashing toward the Demon Emperor.
"Chii Chii Chii!"
The massive Sword Qi arrived instantaneously before the Demon Emperor, without hesitation, slashing at the Demon Emperor's chest.
"Not good!"
