Can you recommend a novel that tells the story of the female protagonist who was originally a princess, but later traveled around the world and became the best in the world?

I've read it a long time ago, so I can't remember the name or the main character's name, but I can roughly remember the plot. I hope that those who have read this novel can tell me the name of the book ~
The heroine was a princess, and her mother was a queen. Her mother wanted to have another son, but she didn't like her mother to have another son. The main reason was that she thought she could do what the man could do.
Later, her father sent her to other countries as a guest, but the real purpose was to stir up disputes between countries.
The female lead was very, very smart, and she was also very, very beautiful.
When she was a few years old, she killed someone to protect her mother. In short, a very powerful princess...
In the end, the female lead and the king of another country informed these countries that the female lead had taken the elixir of immortality, but the man did not. The man later died.
That's about it ~~~

Answer 1

I recommend "The Princess Is a Powerful Official" to you. This is an ancient romance novel. It tells the story of a female protagonist who resolutely decides to avenge her past humiliation and transmigrate to the ancient world. In a chaotic world, she stirred up the wind and clouds step by step and finally dominated the world. The story was filled with time-travel struggles and love plots. The female protagonist was witty and humorous, while the male protagonist was a loyal dog man who protected his shortcomings. If you like ancient dramas and love stories, this novel will not disappoint you. I hope you like my recommendation, Mwah ~😗
