Bai Ye curiously glanced at Fang Yuxin, but there was nothing particularly revealing on her face, so he had to refocus his attention on Feng Yue while releasing his Spiritual Sense to carefully perceive.
Upon this perception, he discovered the issue.
The energy in Feng Yue's body was exceptionally pure, a rarity among ordinary superpower users unless they were particularly outstanding. However, it was too farfetched to conclude that Feng Yue had used an Elemental Crystal solely based on this phenomenon.
After all, Bai Ye was not a Wood Element Superpower User and his perception of life force was not as acute as Fang Yuxin's. Fang Yuxin was certain that Feng Yue had used an Elemental Crystal because his life force was much more vigorous than that of other superpower users of the same rank. Moreover, his body's enhancement was also much stronger. All these indicated that he was no ordinary superpower user!
