Supreme Queen

I never thought that I would become a queen, because I was born with the destined throne; but I never thought that I would govern a powerful empire, just because he made me his queen after he unified the world; I never thought that my posthumous title after death would be "Supreme", because he is this Emperor Gaozu of the dynasty, then I should also be nicknamed "Gao", but before I died, I saw a testament left by my grandson, the third generation king of this empire, who presented to me. I could not see clearly a large row of words praising virtues, but in the blur, I saw those four words: "Supreme Queen". Conception:
