"Linjiang Immortal" tells the story of Hua Ruyue and Bai Jiusi, who were transformed by the essence of Hongmeng. They coexisted with each other but turned against each other due to misunderstanding. After Hua Ruyue lost her son in the calamity, she was reincarnated as Li Qingyue, a disciple of the Jingyun Sect. She married and divorced three times, and had a love-hate relationship with Bai Jiusi, who regarded her as a substitute. In the midst of revenge and suspicion, the two gradually uncovered a larger conspiracy behind it - the villain Xiao Jingshan wanted to destroy the Wuliang Monument and disrupt the three realms for revenge. In the end, the two put aside their grudges and fought side by side to defeat Xiao Jingshan. After Bai Jiusi died, Hua Ruyue borrowed a magic weapon to go back in time and space to resolve past misunderstandings, reunited with Bai Jiusi, and agreed not to separate again.
