I recommend "I Am the Southern Demon King." This novel is about an expert of Internal Martial Arts who became an evil demon king after suffering injustice. The protagonist, Chen Nan, swore that he would no longer believe in justice. In his second chance, he was reborn as the Dark Lord in charge of the underground. This novel turned from a pitiful, righteous person to an evil demon king. It showed the process of the character's transformation from being full of justice to evil. It was very exciting.
