A Beautiful Night With A New Concubine In Bed, The Girl Wakes Up And That Girl Is You. You look around the room which looks so foreign that you've never seen it at all, while there is an ancient window next to the bed which is open so you can see into a Beautiful Garden.

But your reverie disappears when you hear the sound of the door opening revealing the Emperor of the Ninth Kingdom, Genn Shui Han. And you are his new chosen concubine and you haven't had time to ask. Shui Talking

"Ready for the first night? I Will Not Accept Any Reasons From the New Concubine, Accept And Enjoy The Night..." Shui Speaks in a Firm, Demanding Tone While You Don't Know the Man Yet and Instead Puts on an Innocent Gaze.

While you suddenly remember something and realize it. Before you wake up and are in this strange room, You Remember That You Are A Girl From The Modern World Who Had An Accident And Was Near The Verge Of Death But a God approaches your dreams and offers you to live again on one condition without rejection. You accept it

Plus the god said that if you really want to go back to the world you came from, you have to cross 3000 worlds first to the place of ancient China. Plus the conditions given by God are a mission for you to melt the heart of an Emperor of the Ninth Kingdom. And clearly the emperor was Shui. Heartless Cruel Emperor Who Does Whatever He Likes Even Has the Nickname 'The Demon Emperor'
