Chen Mu was regarded as a madman by the world until his mother crawled out of the coffin and called him 'son'. She was intact, with a gentle smile, but she whispered 'it's time to change' every night. His twin brother Chen Huai returned, his eyes dull, but he recognized that the body was not his mother's. The mute woman in the funeral parlor carved the coffin to send a message, the Feng Shui master Zhao Jin laid seven layers of Yin locks, and the witch Lin Sangu in the mountain lit seven copper coffins - it turns out that what the Chen family has been worshiping for generations is not the ancestors, but the sleeping mother goddess of the earth. When his mother begins to eat the shadows of those close to her, Chen Mu must tear apart the curse of his bloodline with his own hands between saving her and destroying the entire city.
