After My Fiancé Exchanged My Life with His Little Childhood Sweetheart, He Regretted It and Went Crazy

I am an evil being who can conquer heaven and earth, but my destiny can make the cursed Xie family safe for the rest of their lives, as long as the Xie family marries me before the age of 25. Xie Guanlan fell in love with me at first sight and took great care of me. After learning that my grandma was sick, she was sent to a private hospital. But one month before we got married, he brought Xiao Qingmei to me and asked me to change her life. "Wen Yao, I can forgive you for the lies you told to marry into the Xie family, as long as you change your life for Wanting." "Don't worry, after I change my life, I will marry you as promised. However, Wanting has been in poor health since she was a child. I don't worry about her being alone outside." He didn't even care about my life or death and carved 108 magic circles on my body. But he doesn't know that not everyone can change my life.
