I feel that the novel 'First-grade Crown Princess' meets your needs. The main character, Baby Leng, had shown great talent since she was three years old, but people couldn't see her true strength. Instead, they thought she was a calm and composed loser. In this ancient romance novel, Leng Baowa showed amazing talent and strength in the battle of kidnapping the bride. She had unique means and did not lose her wisdom. I hope you will like this novel with a strong and unassuming protagonist.
