The ancient war god Xuancheng was framed by the Heavenly Emperor. His beloved Lingxi pierced his heart with her own hands and pushed him from the Executioner's Terrace. His remaining soul fell into demonic darkness and became a brutal Demon Sovereign, carrying a thousand years of hatred as he searched for her reincarnation.
In the human realm, the physician Lingxi has forgotten her past. A single act of kindness leads her to save him when he is gravely wounded, and she is imprisoned in his demon palace and tormented without end. He hates her to the bone, yet cannot bear to let her go, torn between love and hatred. She is innocent and softhearted, inexplicably aching for his loneliness. Only when her memories begin to return does she learn that neither of them had a choice back then.
Fate is rewritten, and love becomes a calamity. Healing and destruction exist side by side, misunderstandings cling to the bone, and love and hatred offer no easy redemption. In the end, he defies heaven with a love so fierce that his soul is about to scatter, while she sacrifices herself to secure his peace. A thousand years of devoted love culminate in a tragic song of fate, one that can never find fulfillment, even in death.
