Intangible cultural heritage embroidery x sacrificial Celestial Master ability. The heroine possesses the ancestral "life-embroidering technique" - she can use silk thread to sew up wounds, and she can also use silk thread to sew up the souls of dying people. But the cost of this craft is the transfer of one's own lifespan. The male protagonist finds her not to save himself, but to save his father who died in the war thirty years ago - he wants the female protagonist to embroider a "dead man's skin" so that his father can come back to life and sit on the position of warlord. The heroine herself is trapped in the moral deadlock of "should I save the person who killed my mother, or should I kill him myself?"
