Transmigrate + reborn (and both of them are reborn): One body, two souls. One is a princess reborn to seek revenge. In her past life, she was hopelessly lovesick; in this one, she vows to make him fall in love with her, then dump him. The other is a modern woman who transmigrated into the past and just wants to slack off. In her previous life, she earned a measly 1,800 yuan a month and worked herself to the bone, only to have her soul mistakenly seized by the Black and White Impermanence. She visits the King of Hell's palace, discovers the mistake, and hurries back, only to find that her body has already been sent to the crematorium and turned to ashes and a wisp of smoke. Then she arrives in an unknown dynasty and starts slacking off. But now there's another problem: it turns out I'm a stand-in in someone else's scheme to make a killer do their dirty work...
Ah! Why? Heaven gave me the identity of a princess, not so I could slack off, but so I could fight palace intrigues and clean up after that princess...
