The Wild Consort Throws Her Weight Around

A top assassin transmigrated, transforming a timid woman into someone brimming with confidence and unmatched intelligence. She takes on her wicked elder sister and her stepmother, only to be presented with a rooster to stand in for the groom on her wedding day. That was more than she could tolerate. She killed the rooster with her own hands, splattering blood across the wedding hall, then cooked it into soup and sent it over.
