😋I recommend to you the novel "Rebirth of the God", a fantasy novel from another world. Although she wasn't the male protagonist's sister, the female protagonist was Dongfang Qingxuan. It was a story about the rebirth of a dark god of destruction who had been destroyed by the gods. She had a pair of Soul Leaving Eyes that could see through the seven emotions and six desires. In a world where the strong were respected, she could do whatever she wanted. I hope you like this fairy's recommendation. Muah ~😗
