Young Lin Yan enters Netherworld Valley with a shard of blood jade, only to be drawn into a thousand-year feud between the Tianyan Sect and the Wu Clan as he searches for the truth behind his parents' deaths. When his Ice Soul Spirit Physique resonates with the blood jade, the two sides of the Reverseworld Seal gradually come to light. He is not only a blood jade medium, but also bears the fate of unraveling the mystery of the spirit within the mechanical puppet and confronting the Blood Fiend Sect, which controls the Mask of Impermanence. As memory fragments in Wangchuan Tower shatter, the truth of his origins intertwines with the World-Rending Blood Curse. Between the black iron coffin and the rifts in the cycle of reincarnation, he must uncover the ultimate secret of "defying the world is not defying the Dao" and stop an apocalyptic conspiracy that uses the Myriad Demons Cavern as its furnace.
