Noble Lady Fucha Wants a Promotion and a Raise

This is not a wish-fulfillment novel! The protagonist has no special skills or golden finger. She's an ordinary person whose only advantage is knowing the story. The novel is told from the protagonist's first-person perspective. It does not vilify Zhen Huan or Shen Meizhuang, nor does she befriend them. Zhang Rong, a 30-year-old career woman from the 21st century, transmigrates into Empresses in the Palace as Noble Lady Fucha. If Zhen Huan earns favor, so be it. If An Lingrong harms others, she'll reap what she sows. Zhang Rong says nothing and only wants a promotion and a raise.
