After Binding to a System, I Led My Nation on the Path to Immortality

System + The Protagonist Doesn’t Develop It Themselves + Turns It Over to the Nation +

Strong Female Lead, Male-Oriented Xuanhuan, Conquering the Path to Immortality and Becoming a Great Emperor with an Immortal or Sacred Physique

Looking for books similar to "Want Me to Sign-In Like a Slacker? Sorry, I Prefer to Grind." I want stories with broken-engagement plots, System plots, useless-protagonist System plots, invincible protagonists, master-disciple plots, Heavenly Dao Pavilions, and family-centered plots. Authors, could you write these kinds of stories for female-oriented fiction? I want to see a female lead conquer the path to immortality.

Any Novels About a Female Lead Focused on Making Her Country Stronger, With No CP or a CP With Her Country?

Something like "For the Rise of the Motherland, I Transmigrated into a Book". "Sorry, My Beloved Is the Motherland" recently got me hooked on this kind of story, but there aren't many of them, and I'm a bit picky. I hope lots of fellow readers can recommend some!
