A child born from a forbidden union between a mortal woman and an immortal general is cursed at birth. To save her life, her mother makes a desperate contract with a demon lord: he will keep the child alive for three years, but afterward, the mother belongs to him. Years later, the girl accidentally absorbs part of the demon’s power during a deadly encounter, binding their souls together. Hunted by immortals, feared by demons, and rejected by humans, she slowly discovers the truth: She is not merely human. In her past life, she was the lost Phoenix Sovereign of the Spirit Realm — a being whose death once shattered the balance between the three worlds. Now fragments of her former memories are awakening, and if she fully regains her power, she could either save the realms… or burn them all.
