Traveling Across the Heavens, the Heroine Belongs to Me, and the Hero Carries Me Away

Invincible Writing, Multiple Female Protagonists, Not Too Showy, Not Aggrieved, More Everyday.

I want to read a book similar to "Conan: When Fuheishir Travels Through the World of Science". It can be fan fiction, comics, or various categories, but don't just do it for the sake of success. It's best if the emotional drama is gradual and logical. Not a humanoid succubus. Recommendations from book friends are welcome
