Eerie Descent: From the Start, I Marry a Ghost Bride

【First-person POV + no System + no female lead + not an invincible protagonist story + reborn and transmigrate】 My name is Lin Xi. After I transmigrated to this bizarre world, my parents disappeared. They had been gone for ten years, and I had spent those same ten years wasting away. With nothing to do all day, I could only pass the time writing mystery novels. Of course, my older cousin, Murong Xue, was there to look after me. Then today, for the first time, I was chosen by the bizarre world. As soon as I arrived, I discovered that I was about to get married, and to a ghost bride with SSS-rank power, no less. To stay alive, I played my part in the ceremony. The next day, after the ghost bride told me some hard-to-understand news, I realized that someone seemed to be pulling the strings behind all of this! And that brought a tiny glimmer of light to my drab, colorless world!
