Strong Favor: the Imperial Concubine Descended from Heaven

I'm dizzy, I've traveled through time, and I'm being treated as a treasure and pampered every night, I'm a little confused. Okay, I'll bear with it, because it's so strange here, and I'm lucky to have a prince as my backer! What, for a princess? OK, upgrading is a good thing. Yeah, it's so fun to be a princess. Walking around and bumping into the prince and the girl having sex, I feel so sad that I quit and run away! Unfortunately, she failed repeatedly and was caught, and was tortured even more miserably, leaving her unable to walk for several days. Suddenly, she had an idea and seduced the Ninth Prince to abscond with her. I didn't want to cause the secret guards from other countries to attack and plot, and I almost lost my life. The target was actually her, a beauty sent from the sky. How dizzy! What kind of virtues and abilities does the heroine have? Whose family will she fall into in the end? Whose princess is she?
