Transmigrating into Empresses in the Palace as An Lingrong

When I wake up, I've become An Changzai, the least favored concubine in Empresses in the Palace. What am I supposed to do? I saw with my own eyes the punishment Hua Fei inflicted on Xia Changzai, and I know that now I'm here, I have to survive. My power and status are tied to my life. If I don't fight for anything, I'll suffer and remain out of favor. So let me live An Lingrong's life well in her place.
