Although no one was able to notice what just happened, the tiny fluctuation of soul force was unable to hide from the powerful perceptive senses of the Blue Skirt Lady.
She looked at Ye Xiao in surprise as she never thought Ye Xiao to be able to use a Soul type of martial arts skill to attack the soul of Laohu Qiong.
Yes, what Ye Xiao used to kill Laohu Qiong was not his spear but his Soul Ability: Soul Destruction.
The Blue Skirt Lady was surprised not because Ye Xiao was able to use a Soul-type martial arts skill but because a Soul-type martial arts skill can only be used by people who have awakened the Divine Sense by evolving their Sea of Consciousness into Divine Sea.
Ye Xiao was able to use his Soul Force to kill Laohu Qiong, it could only mean that Ye Xiao was a person with Divine Sea.
