Yes, it appeared in the two books, Demon King Du's Primordial Plan and the Plan to Save the Dark Ancestor. In "Demon Lord Ji Du of the Primordial World," Jiu Yao was one of the Nine Star Lords, and in "Plan to Save the Dark Ancestor," Jiu Yao was one of the male leads. If you are interested in Nine Planet Divine Lord, you can try reading these two novels. I hope you like this fairy's recommendation. Muah ~😗
