Can you recommend a few novels with cold and heartless protagonists?

😋I recommend the following novels with cold-blooded protagonists: " The Glory of Netherill "-An epic fantasy novel written by Dawn C. The pure mage protagonist has no female protagonist throughout the whole process and moves forward steadily. " The Strongest Forbidden Zone Covering the Sky "-A novel written by a general from a different world. The main character is a cold-blooded and ruthless egoist. There is no female protagonist in the entire novel. " The Female Primogenitor is Not to Be Trifled With "-a transmigration novel written by Lucky H. The main character is a cold-blooded and ruthless killer who falls from the altar to hell and rises again. " The Cold King's Unique Favorite: The Defiant Secret Agent Concubine "-A novel written by Ye Manting Zhou. The main character was a peerless killer who later became the Great Xuan's good-for-nothing missy, but she was still cold and heartless. I hope you like my recommendation.
