On a rainy night when the alchemy furnace exploded, Chen Changsheng, an abandoned disciple of Wudang, used his blood as a catalyst to forge the forbidden Daoist scripture, Blood Dragon Devours the Heavens Art. When the Nine-Turn Blood Pill seared through his palm, he glimpsed an even more horrifying secret: the Taotie demon markings beneath his master Xuan Zhenzi’s Daoist robe shared the same origin as the Kangjin Dragon shadow in his own bloodline. As the Seven-Star Soul-Devouring Nails pierced the clouds and the White Bone Claw of the Demon Abyss tore through the earth’s veins, the master and disciple, who had fought each other for ten years, finally realized that the Heart-Devouring Gu sealed their dantians, the Heaven-Mixing Instrument suppressed with gouged-out bones, and the rusted Sword of Peace were all parts of a karmic loop in which each was the other’s sacrifice.
