Ren Feifan added a trace of True Qi to his words as he spoke, the overwhelmingly dominant Nine Yang True Qi from within his body instantly surged into the other person's body!
Moreover, Ren Feifan had already restricted the other's cultivation power with a Formation, leaving Zhou Lingyao utterly without the means to resist.
"Ren Feifan, what are you going to do to me? Do you know who I am? Offending me will undoubtedly lead to your death!"
Zhou Lingyao's hoarse voice screamed, echoing throughout the cave.
However, there was not a trace of emotion on Ren Feifan's face as he took out another silver needle and inserted it.
In an instant, a deep pain swept out.
Zhou Lingyao's face drastically changed. She wanted to break through the Formation's restrictions with all her might and kill Ren Feifan, but it was no longer possible for her now.
Her mouth, due to exerting too much effort internally, leaked a trace of fresh blood.
