A young man who grew up in Huaiyin Town, his parents died young, and he lives with his grandfather Chen Laogeng. He has a simple personality, a little timid, but values friendship. Working as an apprentice in a carpenter's shop in the town, he knew very little about his family's past (especially his grandfather's early years). In order to save him, his grandfather Chen Laogeng used wood from an ancient coffin (Yin coffin) of unknown origin, causing the Chen family to owe a "Yin coffin debt." As a result, my grandfather became seriously ill and was haunted by unknown evil spirits. Chen Mandun's goal is to find out the truth about the "Yin Coffin Debt", find a way to resolve it, and save his grandfather and himself.
