Si Jin was burdened with a bone-corroding curse and was trapped in severe pain all her life. However, she met Ci Ji, who was as gentle as jade in the cold abyss. She fell in love with her at a glance and poured out all her affection.
But destiny is ruthless, and Ciji encounters the ninth heavenly calamity, which is a calamity of certain death. There is no cure within the three realms. Only the art of sacrificing the ancient soul can give him immortality and peace in his life at the cost of all her soul.
Without hesitation, she stepped into the sacrificial circle and saw that he was safe and sound, but her soul was gone, leaving only a trace of her soul wandering in the world.
But she didn't know that the sacrifice had backlash. Although Ciji survived, he was stripped of all emotions and desires, and became an empty shell with no love or hatred, with dead eyes, forgetting all love and the woman who laid down her life for him.
The remnant soul stared at him for thousands of years, watching him live alone and numb. Everyone lamented that she was infatuated and wronged her, but she was filled with regret and just wanted to help him regain his feelings.
She once again awakened his memory and affection at the cost of the annihilation of his remaining soul, but what she got in exchange was for him to go against the will of heaven to find his soul and follow him through life and death.
A sacrifice in the name of love, a sadomasochism that spans life and death, from soul-death to eternal separation, from defying fate and changing fate to fateful entanglement, they have given everything they have. In the end, are they going to exchange half a lifetime of suffering for a belated stay together, or are they unable to escape the fate of eternal loneliness?
