He is not human, but the son of man and demon. The king of Beiyue Kingdom! Immortal beauty, supreme power, thousand-year magic! Just when he was ambitious to unify the world, he failed to cultivate the law, his fate was reversed, he became a woman, and lost all his magic power! Is it fate, or is it inevitable? The sworn enemy in the past turned out to be his (her) man, who was destined to be cruel and ruthless, yet he was as gentle as water to him (her), deeply affectionate and loving in every possible way! A hero for a lifetime, but his relationship is so sad! ... It is destined to be an unparalleled sadomasochism for the ages! "The flower of the other shore blooms for a thousand years and falls for a thousand years. The flowers and leaves will never see each other. Love is not cause and effect, fate is destined to life and death."
