Old Madam Mo was fuming right now as she said "You unfilial child, you will be a nothing without your royal surname. You will not have this easy life anymore. I'm sure you will live a life of a beggar if you return everything that we have given to you. Without us, you are a nothing."
After saying this, she immediately regretted it. She never wanted to say these hurtful things to her precious granddaughter but she was enraged by her words. In an attempt to scare her, she blurted those words. But seems like, matters have gone worse.
