Near the end of the Shang dynasty, King Zhou becomes obsessed with his concubine Daji, who is actually a vixen spirit in disguise as a woman.
King Zhou is a ruthless and bloodthirsty tyrant who uses cruel means to torture and kill those who oppose him, including his own ministers who dared to speak up to him.
Huang Feihu is furious when he learns the truth and he defects to Xiqi (西岐; the precursor to the Zhou dynasty), a vassal state under Shang, bringing along his family and loyal followers.
At the end of the novel, Jiang Ziya grants Huang Feihu the post of "Dongyue Taishan Tianqi Rensheng Dadi" (東嶽泰山天齊仁聖大帝), the leader of the rulers of the Five Sacred Mountains.
