I was reading a uread ad on Facebook, downloaded the app and it didn't take me to the book. Of what I remember the web story has a guy with a name of zong who got bit by a snake. For some reason wex was was the cure, and the lead female, Lin something, was that cure. She was paid by his girlfriend is bai something. The money was to save her mother and brother, but the brother died. Her father who shipped off 8 years prior came back to get her, so she could get married. As he favored his youngest daughter, and didn't want her marrying a guy in a chair. (But it was a ruse to try and call the wedding off). The leads speak, and agree to be married for a month then get divorced. She is going through the marriage to get what belongs to her mother back, and he can't not marry her as it was agreed upon by their mother's. On the morning following the wedding he founds out she is pregnant. And that is where the ad ended. Any help would be great. Including where to read it for free.
