According to the information provided, I recommend the novel, Hegemon of the Heavens, to you. The main character of this novel was the reincarnation of a Great Emperor. He had the soul of his previous life in his body. His innate advantage, coupled with his perfect body, had fused with his soul. After going through hardships, he stepped onto the highest peak of this world step by step. Although it was not mentioned that the protagonist was a little fairy before reincarnation, the name of the protagonist in this novel was Chang Sheng. I hope you like this fairy's recommendation.
