The book that I recommend to you is "The Life of the Reaper". It is a fantasy romance novel. The main character, Ye Zhenzhen, became a Reaper due to an accident. Then, she met a willful demon king. The interaction between the two of them was very funny. There were also many cute little ghosts and the funny King of Hell. If you like novels about useless Taoist priests and ghosts, this book will not disappoint you. It's also a first-person novel! I hope you like my recommendation, Mwah ~😗
