Yue Qingqing revealed her ability in front of Jun Feifei for her own reasons.
For one thing, Jun Feifei was a stubborn girl. If she left the girl to wander the streets alone, who knew what dangers she might encounter, so she had no choice but to bring her along.
Secondly, the other party was just a girl of a little over six years old. Even if she did blab something, everyone would just laugh it off as a child's nonsense and would never believe Jun Feifei's words.
Time was also of the essence. In ten more minutes, the nurse would come in again.
For the moment, Yue Qingqing couldn't think of a better strategy and had to resolve the situation quickly.
Finally, when all the energy gathered at her chest, Yue Qingqing successfully forced the true form of this thing out with her Spiritual Energy.
A mass of black muck appeared on Qu Ruorui's chest, from which one could faintly hear bloodthirsty howls.
