Princess Agent's Cultivation Guide

I was a top-notch agent in my last life and a member of the Chinese Dragon Group. I chose to destroy my enemies all by myself despite the cost being my own life. After rebirth, I found myself already married to someone, some handsome prince who was said to have turned into a demon!

But wait! I have NEVER dated anyone neither in my last life, nor this life, how could I become a married women so soon?! My new body is fragile and weak, yet I won't allow it to be a problem on my way of cultivation. Most importantly, where is my husband?

...Anyway, in this fantasy world, I will live this life the way I like!
