Rong Ruo was dead, yet one could say she was still alive.
In fact, Rong Ruo was from the Soul Spirit Race. In addition, Rong Ruo had a dual soul, her main soul being female and the secondary one being male. According to the normal growth process, when she reached maturity, her secondary soul should have disappeared. The problem occurred the day Rong Ruo's home was attacked.
At that time, Rong Ruo was still very young and had both souls in her body. Witnessing the sheer carnage and bloodshed on that day was a huge shock to her system. As a result of this shock, her main soul took a backseat and became a bit fragile and her secondary soul had to take control of her body in order to preserve and protect it.
Jun Wu Xie and the others usually saw Rong Ruo as a female because her main soul was female and her body had settled. But in times of great stress, her main soul would retreat and the secondary, male soul could take control of her body.
