The Purple Flame Demon Saber slashed at Lu Yu's arm, barely breaking the skin, but not cutting deeply into the flesh before being stopped by the muscles. However, the purple-black flames on the saber caused Lu Yu considerable pain.
The pain was so intense that he couldn't control the muscles in his arm, and the muscles that clamped the Demon Saber lost strength. The saber sliced through the tough muscles like special rubber, stopping only when it hit bone.
The Purple Flame Demon Fire was burning Lu Yu's soul, and the pain of a burning soul is unbearable for humans.
Lu Yu had cultivated the Dou Shen Art, so his spiritual power was much stronger than that of an ordinary Martial Cultivator. His soul was also much more resilient, allowing him to withstand the agony of soul-burning without immediately losing all combat ability.
Liu Feng had never before pushed the Purple Flame Demon Fire to such extremes.
