The Entire Shen Family Died for the Country, and Nineteen Orphan Girls Guarded Yanmen Pass.

Official Novel, Single Female Protagonist, No Ambiguity

I would like to read a book similar to "Re-taking the official path and rising higher step by step (The official path is blazing)". We don't want multiple ambiguous heroines, we have to rely on the heroine to take the lead throughout the whole process.
