【Mysterious Miaojiang, ten thousand Gu devour the heavens. When blood-red Gu markings crawl across a boy's back, is it the descent of the Witch God, or the end of humanity?】
During the Wanli reign of the Ming dynasty, Miaojiang in Guizhou is battered by the erosion of Han culture and oppression by the authorities. Ajiu, a boy from the Mashan Miao village, is forced onto the path of Gu cultivation after his father dies protecting the Miao ancestral witch's secret treasure. A finger severed as an offering, hundreds of insects entering his body, a blood centipede acknowledging him as its master... Through the twin agony of Han Chinese massacres and the backlash of Gu arts, he gradually uncovers the thousand-year-old secret of the ancient Chiyou tribe's symbiosis with the blood centipede. The so-called “raising Gu” was, in truth, a defiant spark planted in the Miao people's blood by their ancestral witch, to fight back against the oppression of Heaven's law.
