Pearls on Brocade

In his previous life, Xie Moyan was branded with the curse of having killed his mother. Morally blackmailed all his life, he saw hardship as redemption and endurance as a virtue, only to be poisoned and buried alive by the person who shared his bed. Given another chance at life, Xie Moyan is as cold and hard as a blade. He humiliates scumbags, beats up his stepmother, and tears into his sanctimonious relatives. If I have no morals, you can't use them to blackmail me!
