Can you recommend a novel with only one female protagonist, a cold and ruthless protagonist, and a story that includes elements such as cultivation, supernatural powers, and the underworld?

I recommend "God's Immortal Cultivation Journey." This book is a supernatural novel. The protagonist, the unscrupulous demon, suddenly became an omnipotent God. What kind of wonderful story will happen? However, it was important to note that there was no female protagonist in this book. The protagonist was cold and ruthless, and he killed decisively. Those who liked this type of book could click on it. I hope you like this fairy's recommendation. Muah ~😗
