I Transmigrated into a Tragic Romance as a Useless Concubine, but I Cultivate Immortality and Go Off the Rails

Looking for a Badass Female Lead and a Totally Satisfying Story

Something like "Miss Su, Your Husband Has Fallen" and "Reborn: This System's Style Is All Wrong". It doesn't have to be realistic.

Are There No Decent Female-Oriented Novels Without Romance? Looking for Strong Logic and Good Writing

Looking for books like All Men Are Beneath My Skirts; Without Men, I Become a God. No characters getting stupid, no illogical plot, no melodrama, and please spare me the awkward jokes and comedy. I don't want the protagonist to have so many golden fingers.

The Female Lead Is the Only Cultivator After Being Reborn in Ancient Times

No CP, the Heroine Is the Only One with Magic and the Ability to Cultivate Immortality. Nobody Else Has Powers, so Please Don't Recommend Those.

Similar to Green River stories such as I Rely on an Agricultural System to Become the Imperial Preceptor, I Rely on a Beloved Consort System to Become Qin Shi Huang's Imperial Preceptor, and The Fairy Persona Must Not Collapse. Basically, the female lead pretends to be an immortal and is worshipped as one, or she is genuinely cultivating immortality, and she is the only one who can use magic.
