The Lord Is Enchanting

From a noble lady who lives a leisurely life to a decisive and killing lord, sometimes all she needs is an opportunity. She can rule the world with her hands and enchant the world with her hands behind her back. Even though she lives her life wantonly, what Chen Rao wanted at the beginning was just to live the rest of her life in peace. (PS: 360-degree rolling and cuteness, please collect it~~~~~~~~~~~~~~~) (Also PS: No novice, no rebirth, no system. The protagonist relies on his brains and... The protagonist's halo, ahem.)
