Su Jiuli, an heir to a family of poison doctors in the 21st century, transmigrates one day into the Great Yan Dynasty as the good-for-nothing illegitimate daughter of the Duke of Zhenguo, someone everyone can bully. Her birth mother died horribly, and her stepmother and sisters plotted to frame her, making her the culprit in the old madam’s poisoning and leaving her on the brink of death. But would she ever let others dictate her fate?
A mysterious power entered her body as she transmigrated, and she merged with the remnant soul of the Nine Netherworld Phoenix, a being capable of controlling life and death. Her medical skills are extraordinary, and her mastery of poison is even more astounding. She fights back against the people at the Duke of Zhenguo’s estate who framed her, giving them a taste of their own medicine and making those with ill intentions pay dearly.
The Crown Prince, Xiao Chenye, is of noble birth, yet he has been caught in the whirlpool of the imperial power struggle. He wields the long-lost Netherworld Flame and is both sinister and formidable. By chance, he saves Su Jiuli from a group of pursuers, and the two strike a deal. Su Jiuli helps him eliminate his political enemies, while he helps her take revenge.
In this world where power struggles intertwine with supernatural might, they join forces to face the schemes of the Third Prince, Xiao Chenjue, and the machinations of the Southern Frontier shamaness. The Duke of Zhenguo’s household is secretly allied with the Southern Frontier Shaman Cult, plotting to use living people to refine Gu and control the power of the Nine Netherworld Phoenix in order to overthrow the Great Yan Dynasty. Su Jiuli and Xiao Chenye venture deep into danger to uncover the truth, only to discover an even greater secret behind it all, one involving imperial secrets, ancient powers, and the fate of all the people under heaven.
From the schemes at the Duke of Zhenguo’s estate to the exploration of a mysterious ice cavern and deadly battles in the imperial palace dungeon, danger awaits at every turn. Can they break through their many crises and solve every mystery? Can Su Jiuli avenge herself, rewrite her and Xiao Chenye’s fates, and protect peace throughout the land?
