- **Protagonist**: Chen Huai (19), an orphan from a mountain village with an innate “Yin Fiend Constitution” that attracts ghosts and monsters but makes him impossible to kill. He makes a living carving wood from scraps salvaged from coffins.
- **Golden finger**: Half of the ancestral "Lu Ban Book: Fragment". Objects he carves can temporarily “seal spirits,” activated with his blood.
- **Setting**: “Burial Dragon Village,” a modern parallel world where a living person must be sacrificed to the mountain god every hundred years, or disaster will befall the entire village.
