The Prince of Lieyang's residence was wiped out overnight, leaving a bloody massacre of a hundred lives. The hidden hand behind the carnage was fighting over a mysterious “key.”
Yun Xining is a mysterious young woman with the power to purify black energy. Entrusted with a ward by an old friend, she becomes the teacher of Yan Chang'an, grandson of the Prince of Lieyang.

“Those with blood on their hands cannot be allowed to live.”
Yun Xining's green lotus blooms and the demonic energy disperses, yet even she cannot overcome the treachery of the human heart.
