I haven't figured out how to write an introduction yet, but in short, it's a story about an orphan girl who gradually becomes a powerful female prime minister, and how she goes through ups and downs in the midst of revenge and struggle for imperial power.
You can avoid lightning first:
1. The heroine in the main text has no love line
2. There are male and female protagonists and a single-arrow female protagonist.
3. The heroine is not a pure good person, and some plots conflict with Confucianism.
Intention: Self-reliance and self-reliance
