**Severing the Three Corpses (斩三尸)**: In Daoist cultivation lore, the "Three Corpses" (or Three Worms) are malevolent entities that live inside the human body, craving decay and tempting the cultivator toward death. A common xianxia trope involves "severing" them as a step toward immortality. Here, Danyangzi twists this concept into a parasitic cohabitation, using it to justify his continued existence inside Li Huowang. It’s a brilliant corruption of a respectable cultivation concept into a body-horror nightmare.
