I highly recommend the novel,"The World's Favorite: Ghost Doctor's Fourth Miss." Although the male lead's cultivation had all dissipated and his dantian had been destroyed, he was determined to protect the female lead. Every time, he would protect her at the expense of his own body. As a result, he often fell sick and was injured. Although the female lead had a cheat and great luck, she was a little afraid of the other world. The story of this weak couple living a lively life in this world was really super touching. I hope you like this fairy's recommendation. Muah ~😗
