Heaven's Mandate: The Phoenix's Dream of Perching in the Wutong Tree

A historical romance aimed at female readers, with an imaginative premise, a System, and a spatial golden finger. It should be written in several volumes. First, I need to pin down what the user wants. She may be looking for a clearly structured outline divided into volumes, with each one having its own main storyline and foreshadowing, while combining the System and spatial elements.

A System is relatively uncommon in historical fiction, so it needs to be integrated plausibly. It could take the form of a mysterious object or inner power, such as a jade pendant or ancient book, to better suit the setting. The spatial golden finger could be a portable space where she can grow plants and make pills, or a secret realm with special abilities. Either could help the heroine survive and drive the plot forward.

Next comes the imaginative premise. Romance for female readers needs a love story, but since the user mentions an unusual concept, it might also include fantasy or sci-fi elements such as a time loop, soul swapping, or future technology. The key is making these elements fit a historical setting. For instance, the System might have been left behind by people from the future, or the space could be a gateway to another world.
