A Nightmare Journey That Started from Movies and TV Series

Lu Xun never expected that after a nightmare, he would have the ability to travel through various worlds while sleeping, but these worlds were not normal. Why do prosecutors in Korean dramas have to work part-time to manage the environment? Why do you have to work part-time as an undercover agent in a Hong Kong movie to catch ghosts? Why are there monsters in Jinyiwei's world? Lu Xun was about to cry but had no tears, feeling that he was walking further and further down a road of no return... Ps: This book is also called "A Nightmare Journey Starting from a Food Drama" and "Why Am I Cold Again"
