After Transmigrating into the Ancient Villain’s Ex-Wife, I Turned My Life Around with Intel

I transmigrated into the villain’s ex-wife, and from the start I was facing a divorce decree and a warning that his whole family would be executed! Armed with modern intelligence analysis, I sat in teahouses listening to gossip and intercepted secret letters at courier stations. I even knew exactly how many bowls of rice the villain had eaten the night before. When he raised his sword and demanded, “How did you know my plan?” I pulled out my notebook. “My lord, the military tally your concubine hid is on page three.” I survive by gathering intelligence, and along the way I turn the villain’s schemes upside down. Who says an ex-wife can only be written off? I’m going to become the intelligence chief he can never figure out!
