I recommend "The Primeval Underworld Emperor". In this Xianxia, mythical, and cultivation novel written by the author, Pale Snow Flying Tooth, the main character is a cold and ruthless character. He called himself the Eternal Underworld Emperor and was decisive in killing. He regarded the world as nothing and all living beings as ants. Those who disobeyed him would be killed! Those who were an eyesore would be killed! I don't need a reason to kill you! The plot was tight and thrilling. I hope you like this fairy's recommendation. Muah ~😗
