On the seventh day of March in the third year of Zhenghe, it rained heavily. In the drainage channel outside Bianjing's Nanxun Gate, three male corpses were washed ashore. Five-power magic spells were carved on their chests, and their faces were as ulcerated as toad sloughs. The watchman identified one of them as Nancheng drug dealer Chen Dayan, claiming that he saw a "human-faced Gu baby" crawling through his house last night, and the baby's cry was as shrill as a knife scraping a pottery urn.
