The ten-year-old noble girl Fei Ocean was forced to leave her home on the border and enter the royal capital to receive a "lady's education." However, she soon discovered that she was involved in a mysterious conspiracy that spanned thousands of years. The underground secret room of the Winston family, the imprisoned "vessel" girl, and the strange abilities gradually awakening in her body all point to a forgotten truth-she is the reincarnation of the ancient guardian of balance.
In this world where light and darkness are in sharp opposition, Fei gradually masters the "power of balance" to control two opposing forces at the same time. She made acquaintance with the secret allies of the Silver Sail Chamber of Commerce, and also encountered the deadly pursuit of the Shadow Order. But the greater threat comes from the ancient existence lurking in the shadows of history - the "Messenger of Nothingness", a terrifying force that attempts to destroy everything and return to nothingness.
When the night of the double moon comes, Fei must uncover the ultimate secret of her life amidst royal suspicion, betrayal of allies, and surrounding powerful enemies. She will face a cruel choice: become a weapon for the God of Order to destroy Chaos, or a pawn for the God of Chaos to subvert order? Or... Find a third way, become a true "messenger of balance", and bring new hope to the world in the torrent of fate intertwined by light and darkness?
