I recommend a novel with a female protagonist who has traveled through time.

The female protagonist transmigrated into a novel she had read before and became a dragon (at first, she thought it was a duck). She came to help the male protagonist. There was also a system that had been teaching her. Later, she became a white-haired girl who was very beautiful and could change her appearance.

Answer 1

The novel " Parachute Female Lead: Cold Male Lead, Please Surrender " might meet your needs. The female lead transmigrated into the book and became the vicious female supporting character in the novel of the same name. However, when she met the paranoid male lead, she wanted to retreat and stay away from the main character circle. In the story, the female protagonist was cute and cute in the early stages, but later on, she became independent and self-reliant. The male protagonist was overbearing and stubborn, and finally, his heart belonged to the female protagonist. I hope you like my recommendation.
