If you like novels where the male protagonist is cold and likes to kill, then I recommend "The Great God Is Like Jade, The Cheap Like Rainbow", a game competition-online romance novel. The male lead was a god-level player who liked to kill and was very good at it. However, due to his cold personality and killing habits, many girls were rejected by him. In addition, there was also the female protagonist Xia Wan's resistance and confrontation in the novel. The plot was very compact and exciting. I hope you like my recommendation. Muah ~
