I recommend the two novels,"My Cold Host" and "Blood Sea Sky", to you."My Cold Host" is a sci-fi space-time travel novel. The protagonist became cold in the early stage due to his childhood experiences, but he became gentle and kind in the later stage."Blood Sea Sky" is a Xianxia-cultivation civilization novel. The protagonist is an immortal cultivator who is unscrupulous, sinister, cunning, cold, cruel, and has no female protagonist. I hope you like my recommendation. Muah ~
