Chaos gave birth to all things, and all things have their causes and consequences. Cause and effect goes in cycles. Yet it is an exception in this world. It is a wisp of consciousness, without a body, a name, or memories, and it has wandered the world for a very, very long time. After passing through changes in time and space, from the modern era to ancient times, and seeing the warmth and coldness of human nature, it eventually drifted to Yufeng Mountain. Once a lonely spirit between heaven and earth, it was reborn as a human by a twist of fate, only to suddenly discover itself caught in a raging storm. A mystery of ten years is finally solved, but how can an imperial legacy spanning a hundred generations continue? The mastermind behind it all is her beloved. What will she choose...?
