Woman's Heart

After a caravan slaughter, Fang Yuan summons Woman’s Heart. It floats up, emits reddish purple light, pulls women’s hearts from corpses, turns them into inky purple light lumps, and absorbs them as food while screeching. ^{ch. 694} He later finishes feeding it until it is full at Zhou Xi oasis, then returns it to his immortal aperture without pushing further refinement. Past fullness, more women’s hearts would enter a refinement stage that strengthens the poison further, but he refuses that investment without the Immortal Gu recipe, because a consumable Immortal Gu is gone after one use no matter how strong it becomes. ^{ch. 695}

Using the light of wisdom, Fang Yuan fuses details of poison breath and harboring malicious heart into an incomplete immortal move he names poison spit, with Immortal Gu Woman’s Heart as the core. Each activation leaves large amounts of poison in the body, so the move is incomplete. ^{ch. 745} By the Northern Plains auction, Woman’s Heart sits in the right part of his chest like a baby’s fist, purple-black and linked to his zombie bloodstream, while assisting mortal Gu run reverse refinement that extracts its strength for repeated use instead of one-time expenditure. He keeps the Gu off the auction list for that reason. ^{ch. 748}

In a Gu formation cored on the light of wisdom, Fang Yuan combines Mo Yao’s fake will, Woman’s Heart, and the wisdom path Immortal Gu Unravel Mystery to refine Bo Qing’s Immortal Gu. ^{ch. 997}

A later inventory of Fang Yuan’s Immortal Gu lists Woman’s Heart among his rank six Immortal Gu. ^{ch. 1082}
