In a future world full of relics of the old gods and genetic modification techniques, Jing Ye carries the secret of the "Poison-eating Curse" and embarks on a journey to break the conspiracy of the Five Poison Sect with his contract partner Xuan Li. He not only has to fight against enemies who can rewrite the gene chain, but also faces the heartbreaking pain of relatives and friends being controlled by parasites: some become murderers for their loved ones, some have hidden dangers in the genes of the old gods, some become altars as experimental subjects, and so on.
From the swords and shadows in Zuixian Tower to the puzzle of the altar in the mental hospital, Jing Ye, side by side with Zhuge Xing and other partners, shuttled between the Cthulhu-style weirdness and the joy of martial arts. When the purple smoke of the old god's resurrection rises, he must choose between the price of the contract and the redemption of humanity, uncovering the ultimate connection between the family tragedy twenty years ago and the Five Poison Sect.
