On the bluestone road on a rainy night, Orion Wang Erzhu opened the door of the old medicine shop holding a bloody cloth bag. A seven-inch snow-capped mountain white spirit snake with a silver hairpin slipped out of the cloth. The snake scales were glowing with cold light, and the tooth marks on his ankles were covered with green and black Gu patterns - this was a rare mother-in-law Gu that could not be seen in a century, and its throat was sealed with blood.
