The female lead transmigrates into the body of a princess whose kingdom has just fallen. While they’re fleeing, her maid, who seems to be the original female lead and have a wood spirit root, steals the jade pendant that would let her enter an immortal sect. The female lead has light-and-dark spirit roots and a weak heart, with a divine sword inside it. They say someone with light-and-dark spirit roots appears only once every hundred years.
