I recommend the following novel to you: "Rebirth 97: Return to the Peak". Although it wasn't a prehistoric theme, the story of the protagonist being reborn in 1997 and pursuing the peak of life was very attractive. At the same time, the background of the novel was very close to the modern era, so there were many novel elements. Most importantly, the protagonist had successfully returned to his peak and had a happy family. It was very heartwarming. I hope you like my recommendation. Muah ~
