The Road to the Back Room

People have always thought that the back room is just an urban legend, but it has always existed, and the dangers in the back room threaten homeless people all the time. Even the protagonist Zhang Lu will almost die sometimes. The author is new to this and doesn't know much about some parts of the back room, so don't comment if you don't like it. Make up the word count. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
