Featuring the mythological and fictional version of the popular Chinese figure Jiang Ziya, the plot is loosely based on the novel Investiture of the Gods by Xu Zhonglin.

Unwilling to accept that the girl was supposedly an illusion created by the fox spirit, Jiang Ziya is stripped of his powers and banished to the North Sea until he can correct his mind.

Jiang spends ten years on earth despondent with his friend Shen Gongbao and his pet, Si Bu Xiang.

After a scuffle over a map, Jiang Ziya decides to accompany her to Youdu Mountain, where she believes her father is waiting for her, trailed by Shen Gongbao.

At Youdu mountain, Xiao Jiu encounters the King of Zhou, who explains that she is tied to the original fox spirit and must be killed in order to fully defeat the former.

Jiang Ziya along with Shen Gongbao manage to fight off the fox spirit together, at the cost of the death of Si Bu Xiang.

As the fox spirit regains her power, she explains to Jiang Ziya that originally, she had been promised Godhood but had instead been turned into a scapegoat to fight against to unite the three realms.

Jiang Ziya realises his true powers come from his self-confidence and not the will of heaven, and manages to seemingly save the girl, only for her to be killed by the guillotine.

The film tells the story of the mythological and fictional literary version of Jiang Ziya from the Investiture of the Gods, a gargantuan Ming-dynasty (1368–1644) shenmo novel that is traditionally attributed to Xu Zhonglin, and incorporates various existing myths into a wider narrative.
