The Silenced Sister's Revenge

My sister and I were both poisoned and rendered mute. One antidote. My sister snatched it. She became Crown Princess. I married a general, becoming First-Rank Imperial Dame. My sister locked me in a beast cage, where I met my demise. I open my eyes again. Before me lies an antidote. My sister pushes the pillbox to my lips. I calmly pick up the pill. In this life, I can finally speak for myself. It's a pity for my sister. She chose to break down the gates of hell.
