Nangong Ling has known since childhood that she carries a great mission.
She holds the key to travel between two worlds, yet belongs to neither.
While gathering immortal herbs one day, she nearly turned the Ghost Lord into a eunuch, making an enemy of him ever since.
Through him, she gradually learns the secret of her origins and begins to uncover the purpose of her existence in this world.
But she never expected that this insufferable man would mistakenly think she had taken his yang essence and demand that she take responsibility.
On a dark and windy night, the man comes to her door again. "Share my bed tonight, and I'll spare your life."
"Han Luoyan, aren't you afraid your happiness for the rest of your life will be ruined?"
She can handle both righteous and demonic paths, and slay those of Buddhist and demonic schools alike. Why should she fear a mere Ghost Lord?
Unfortunately, in this world, evil ghosts run rampant, and the Ghost Lord is hard to shake off.
After he blocks her from completing her mission yet again, she finally snaps.
"I've told you eight hundred times: You still have your yang essence. I never slept with you. Can you stop pestering me?"
Han Luoyan smugly pulls her into his arms. "I know your secret. If you want to roam this world freely, my yang essence is just what you need. And I need a woman I don't dislike to keep all kinds of people from bothering me. How about a deal?"
