Hao Ren was about to put on his shirt when he heard the washroom door behind him slide to the side. Instinctively he turned around and was stunned. Before him stood Han Lingshi, cloaked in the flickering cloak of water vapors. He beauty was on exhibition for Hao Ren to see.

The lady smiled enchantingly and replied, "So, what if I burn? Are you forgetting that I have the providence of a phoenix? It is sort of my talent to rise from the ashes after burning in my own flames."
